Abstract

The present invention provides a cell reselection method, comprising: generating cell reselection parameters corresponding to different moving speeds, and notifying a terminal of the cell reselection parameters, so that the terminal performs cell reselection by using the cell reselection parameter corresponding to the moving speed of the terminal, wherein the cell reselection parameters comprise at least one or any combination of prohibition information, a cell reselection priority set, a cell reselection frequency set, a cell reselection time set, and a reselection criterion threshold set. Correspondingly, the present invention also provides a base station, a terminal, and a system. By means of the technical solution of the present invention, terminals of different moving speeds can reselect most suitable cells, which prevents the terminals from performing unnecessary frequent reselection in an idle state, and also prevents the terminals from performing unnecessary handover after entering a connection state, thereby reducing unnecessary power consumption overheads of the terminals.

Description

小区重选方法、基站、终端和*** 技术领域 Cell reselection method, base station, terminal and system

本发明涉及无线通信技术领域，具体而言，涉及小区重选方法、基站、终端和***。背景技术 The present invention relates to the field of wireless communication technologies, and in particular, to a cell reselection method, a base station, a terminal, and a system. Background technique

在无线移动通信***中，终端的状态分为连接状态和空闲状态。在空闲状态下，终端需要从基站处接收广播信息，接受服务。由于终端的移动性，为了其能够正确接收基站发送的广播信息，终端需要及时地进行小区重选，选择能够提供给自己正确广播信息的小区。如果被选择的小区能够满足小区重选条件，终端就驻留在这个小区，直到重选到另外一个小区。 In a wireless mobile communication system, the state of the terminal is divided into a connected state and an idle state. In the idle state, the terminal needs to receive broadcast information from the base station and accept the service. Due to the mobility of the terminal, in order to correctly receive the broadcast information transmitted by the base station, the terminal needs to perform cell reselection in time, and select a cell that can provide correct broadcast information to itself. If the selected cell is able to satisfy the cell reselection condition, the terminal camps on the cell until it reselects to another cell.

移动终端在网络中运动时，在连接或空闲状态下都可以估计自己的运动状态。在空闲状态下，终端可以在配置的时间段内累计自己的有效小区重选次数，然后将计数结果与***配置的门限值比较，得到自己的运动状态。其中，运动状态可以分为三个类别：高速、中速或普通。在连接状态下，终端可以在配置的时间段内累计自己的有效切换次数，然后将计数结果与***配置的门限值比较，得到自己的运动状态。其中，运动状态也可以分为三个类别：高速、中速或普通。 When the mobile terminal moves in the network, it can estimate its own motion state in the connected or idle state. In the idle state, the terminal can accumulate its own number of valid cell reselections within the configured time period, and then compare the counting result with the system configured threshold to obtain its own motion state. Among them, the motion state can be divided into three categories: high speed, medium speed or normal. In the connected state, the terminal can accumulate its own effective number of switching times in the configured time period, and then compare the counting result with the system configured threshold to obtain its own motion state. Among them, the motion state can also be divided into three categories: high speed, medium speed or normal.

在现有的移动通信***中，随着业务的迅速发展，原有的宏基站服务能力有限，而且随着建筑等地貌的变化，会存在一些覆盖盲点。因此，运营商可以在热点区域或覆盖盲点区域布置小小区，提升***的服务能力和覆盖范围。一般来讲，小小区的半径较小（50 米左右），其基站相对宏小区基站较为筒单，布网更为灵活。小小区的覆盖范围可以是在宏基站的覆盖范围之内（主要用来增加***容量），也可以是在宏基站的覆盖范围之外（主要用来增强覆盖）。小小区所在的频率可以是独立于宏基站的频率，也可以是与宏基站共用频率。如图 1 所示，假设所有宏基站对应的宏小区 102组成宏小区层 1020 , 所有的小小区 104组成小小区层 1040。由于小小区 104的半径较小，如果某个处于空闲状态的终端在同时存在宏小区层 1020和小小区层 1040覆盖的地方高速运动，如果终端选择接受小小区层 1040 的服务，即驻留在小小区层 1040, 就需要频繁的执行小区重选，而重选过程中涉及小区搜索、测量、重选判决等步骤，而重选过程完成后又需要获取服务小区***信息等，这些都会增加终端的功耗。因此，这种频繁的小区重选应该尽量避免，也就是说高速终端应该尽量驻留在宏小区层 1020。同时，类似的，如果高速终端处于连接状态，为了避免频繁切换，它也应该尽量在宏小区层 1020 接受服务。而当终端由空闲状态到连接状态进行转换时，它首先要同空闲状态下的服务小区进行通信，接受其服务。如果高速终端在空闲状态下驻留在宏小区层 1020 , 转换为连接状态下就可以直接在宏小区层 1020 进行通信。而如果高速终端在空闲状态下驻留在小小区层 1040 , 在转换为连接状态时，首先在小小区层 1040进行通信，然后还要切换到宏小区层 1020, 增加了不必要的切换开销。 In the existing mobile communication systems, with the rapid development of services, the original macro base station has limited service capabilities, and there will be some coverage blind spots as the landscape changes such as buildings. Therefore, the operator can arrange small cells in the hotspot area or the coverage blind spot area to improve the service capability and coverage of the system. Generally speaking, the radius of the small cell is small (about 50 meters), and the base station is relatively simpler than the macro cell base station, and the network is more flexible. The coverage of the small cell may be within the coverage of the macro base station (mainly used to increase system capacity), or may be outside the coverage of the macro base station (mainly used to enhance coverage). The frequency at which the small cell is located may be a frequency independent of the macro base station, or may be shared with the macro base station. As shown in Figure 1, assume that all macro base stations correspond to macros. The cells 102 form a macro cell layer 1020, and all of the small cells 104 form a small cell layer 1040. Since the radius of the small cell 104 is small, if a terminal in an idle state moves at a high speed in the place where the macro cell layer 1020 and the small cell layer 1040 are simultaneously present, if the terminal chooses to accept the service of the small cell layer 1040, it resides in the terminal. The small cell layer 1040 needs to perform cell reselection frequently, and the reselection process involves steps such as cell search, measurement, and reselection decision, and the reselection process needs to acquire the service cell system information, etc., which will increase the terminal. Power consumption. Therefore, such frequent cell reselection should be avoided as much as possible, that is, the high speed terminal should reside as much as possible in the macro cell layer 1020. At the same time, similarly, if the high-speed terminal is in the connected state, it should also accept the service at the macro cell layer 1020 in order to avoid frequent handover. When the terminal is switched from the idle state to the connected state, it first needs to communicate with the serving cell in the idle state to accept its service. If the high speed terminal resides in the macro cell layer 1020 in the idle state, it can be directly communicated at the macro cell layer 1020 when converted to the connected state. If the high speed terminal resides in the small cell layer 1040 in the idle state, when it is switched to the connected state, communication is first performed at the small cell layer 1040, and then also switched to the macro cell layer 1020, which increases unnecessary switching overhead.

因此，基于上述提出的问题，需要一种新的用于终端进行小区重选的技术策略，可以使不同移动速度的终端重选至最适合的小区，避免终端在切换至连接状态后进行不必要的切换，从而降低终端不必要的功耗开销。发明内容 Therefore, based on the above-mentioned problems, a new technical strategy for the cell to perform cell reselection is needed, so that terminals of different mobile speeds can be reselected to the most suitable cell, and the terminal is prevented from being unnecessary after switching to the connected state. Switching, thereby reducing unnecessary power consumption overhead of the terminal. Summary of the invention

实施例一 Embodiment 1

图 2示出了根据本发明的一个实施例的终端根据小区重选参数进行小区重选的示意图。 2 is a diagram showing a cell performing cell reselection according to a cell reselection parameter according to an embodiment of the present invention.

如图 2所示，在根据本发明的一个实施例的终端根据小区重选参数进行小区重选的技术方案中，由基站 202生成对应于不同移动速度的终端的小区重选参数，比如根据移动速度将终端分为高速终端、中速终端和低速终端，则对于同一个小区重选参数，基站 202 将生成对应的高速终端参数、中速终端参数和 /或低速终端参数。而对于终端而言，假定终端 204A 为高速终端，则终端 204A 在接收到高速终端参数、中速终端参数和低速终端参数时，可以选用高速终端参数进行小区重选操作，而对中速终端参数和低速终端参数则可以不作响应；假定终端 204B 为低速终端，则终端 204B 可以选用低速终端参数进行小区重选操作，而对高速终端参数和中速终端参数则可以不作响应。类似地，对于中速终端则可以选用中速终端参数（图中未示出）。 As shown in FIG. 2, in a technical solution in which a terminal performs cell reselection according to a cell reselection parameter according to an embodiment of the present invention, a base station 202 generates cell reselection parameters of terminals corresponding to different moving speeds, for example, according to a mobile station. The speed divides the terminal into a high speed terminal, a medium speed terminal and a low speed terminal, and for the same cell reselection parameter, the base station 202 will generate corresponding high speed terminal parameters, medium speed terminal parameters and/or low speed terminal parameters. For the terminal, if the terminal 204A is a high-speed terminal, the terminal 204A can select the high-speed terminal parameter for the cell reselection operation and the medium-speed terminal parameter when receiving the high-speed terminal parameter, the medium-speed terminal parameter, and the low-speed terminal parameter. The low-speed terminal parameters may not respond; assuming that the terminal 204B is a low-speed terminal, the terminal 204B may select a low-speed terminal parameter for cell reselection operation, but may not respond to high-speed terminal parameters and medium-speed terminal parameters. Similarly, medium speed terminals can be selected for medium speed terminals (not shown).

当然，基站 202根据需要也仍然可以生成不区分终端运动状态的通用小区重选参数（也就是现有技术中的小区重选参数，图中未示出），可以被没有判断运动状态的终端采用；也可以被虽然判断了运动状态、但是基站 202 未生成其运动状态对应的小区重选参数的终端采用，比如当基站 202 仅生成低速终端参数时，假定终端 204A 为高速终端，则可以利用上述通用小区重选参数执行小区重选。 Certainly, the base station 202 can still generate a common cell reselection parameter (that is, a cell reselection parameter in the prior art, which is not shown in the figure) that does not distinguish the motion state of the terminal, and can be adopted by the terminal that does not determine the motion state. It may also be adopted by a terminal that determines the motion state but the base station 202 does not generate a cell reselection parameter corresponding to its motion state. For example, when the base station 202 only generates a low-speed terminal parameter, it is assumed that the terminal 204A is a high-speed terminal. The general cell reselection parameter performs cell reselection.

通过上述方式，则基站 202可以控制不同移动速度的终端的小区重选结果，比如对于高速终端，可以控制其尽可能地重选至宏小区，避免当重选至小小区时，在空闲状态下进行不必要的频繁重选，同时也避免在进入连接状态后需要进行的不必要切换，导致增加终端不必要的功耗开销。当然，基站 202 可以采用类似的方式对任意移动速度的终端进行小区重选的控制，但基站 202并不一定需要对所有移动速度的终端都进行控制，比如当基站 202 仅对高速终端进行控制时，则可以仅生成对应的高速终端参数，而对其他运动状态或没有判定状态的终端仍旧采用通用小区重选参数。或者，基站 202可以生成同时对应于多种移动速度的终端的参数，比如同时对应于高速终端和中速终端的参数，则高速终端和中速终端都可以对该参数做出响应，从而实现对这些终端的小区重选结果进行控制，而对其他运动状态或没有判定状态的终端仍旧采用通用小区重选参数。 In the above manner, the base station 202 can control the cell reselection result of the terminal of different moving speeds, for example, for the high speed terminal, it can be controlled to reselect to the macro cell as much as possible to avoid seriousness. When selecting to a small cell, unnecessary frequent reselection is performed in an idle state, and unnecessary switching that needs to be performed after entering the connection state is also avoided, resulting in an unnecessary power consumption overhead of the terminal. Certainly, the base station 202 can perform cell reselection control on the terminal of any moving speed in a similar manner, but the base station 202 does not necessarily need to control all the terminals of the moving speed, for example, when the base station 202 only controls the high speed terminal. Then, only the corresponding high-speed terminal parameters can be generated, and the common cell reselection parameters are still adopted for the terminals with other motion states or without decision states. Alternatively, the base station 202 can generate parameters of terminals corresponding to multiple moving speeds, for example, parameters corresponding to the high speed terminal and the medium speed terminal, and the high speed terminal and the medium speed terminal can respond to the parameter, thereby implementing the pair. The cell reselection results of these terminals are controlled, and the common cell reselection parameters are still used for terminals with other motion states or without decision states.

下面将结合图 3至图 7, 分别从基站 202和终端（包括终端 204A、终端 204B 以及其他移动速度的终端）两侧，结合小区重选参数的类型及具体的细节，对图 2所示的实施例进行更为详细的说明。 3 to 7, respectively, from the base station 202 and the terminal (including the terminal 204A, the terminal 204B and other mobile speed terminals), combined with the type and specific details of the cell reselection parameters, as shown in FIG. 2 The examples are described in more detail.

如图 3所示，对于基站而言，其生成小区重选参数以供终端进行小区重选的流程包括： As shown in FIG. 3, for a base station, a process for generating a cell reselection parameter for a terminal to perform cell reselection includes:

步骤 302 , 生成对应于不同移动速度的小区重选参数，并向终端通知所述小区重选参数，以由所述终端利用对应于自身移动速度的小区重选参数进行小区重选；其中，所述小区重选参数包括以下至少之一或其组合：禁止信息、小区重选优先级集合、小区重选频率集合、小区重选时间集合、重选准则门限值集合。在该技术方案中，通过采用本发明提出的小区重选参数中的任意一种或多种，并生成针对不同移动速度的小区重选参数，从而使终端能够利用与自身的移动速度相匹配的小区重选参数实现小区重选操作。由于终端的移动速度与小区重选参数相匹配，因而不同移动速度的终端重选到的小区类型也可能存在差异，比如使得高速终端尽可能重选至宏小区，从而减少终端的重选次数和避免进入连接状态后执行不必要的切换，降低终端的功耗开销。 Step 302: Generate cell reselection parameters corresponding to different moving speeds, and notify the terminal of the cell reselection parameters, so that the terminal performs cell reselection by using cell reselection parameters corresponding to the mobile speed of the mobile terminal; The cell reselection parameter includes at least one of the following or a combination thereof: a forbidden information, a cell reselection priority set, a cell reselection frequency set, a cell reselection time set, and a reselection criteria threshold set. In this technical solution, by using any one or more of the cell reselection parameters proposed by the present invention, and generating cell reselection parameters for different moving speeds, the terminal can utilize the matching speed of the mobile terminal. The cell reselection parameter implements a cell reselection operation. Since the moving speed of the terminal matches the cell reselection parameter, the cell type reselected by the terminal with different moving speeds may also be different, for example, the high speed terminal is reselected to the macro cell as much as possible, thereby reducing the number of reselection times of the terminal and Avoid unnecessary switching after entering the connection state, reducing the power consumption overhead of the terminal.

针对本发明中提出的上述五种小区重选参数，下面将分别进行详细说明： (一）禁止信息 The above five kinds of cell reselection parameters proposed in the present invention will be respectively described in detail below: (1) Prohibition information

小区需要满足一定条件后，才能被终端重选，其条件之一即该小区不能是被限制的。具体而言，比如，不能是被禁止的或者被运营商预留的。基站在***消息中会广播相关的限制参数，比如 "禁止" 参数（ cell Barred ) 和 "运营商预留 " 参数 (cell Reserved For Operator Use)。终端读取 ***消息中与 "限制" 的相关参数，如果这些参数表明当前基站是被限制重选的，比如被禁止或被运营商预留的，终端是不能重选到当前小区的。 The cell needs to meet certain conditions before it can be reselected by the terminal. One of the conditions is that the cell cannot be restricted. Specifically, for example, it cannot be forbidden or reserved by the operator. The base station broadcasts relevant restriction parameters in the system message, such as "cell barred" and "cell reserved for Operator Use". The terminal reads the relevant parameters in the system message and the "limit". If these parameters indicate that the current base station is restricted to reselect, such as being forbidden or reserved by the operator, the terminal cannot reselect to the current cell.

因此，基站可以通过广播特殊的 "禁止" 信息来禁止特定运动状态的终端驻留到本小区。比如，如果当前小区不希望高速终端驻留在此，基站可以广播针对高速移动终端的禁止信息，这样，高速终端在读到这个针对高速终端的禁止信息之后就不会驻留在当前小区了，而其他运动状态或没有判断运动状态的终端即便读取到这个消息也不会受到影响。 Therefore, the base station can prohibit the terminal of the specific motion state from camping on the own cell by broadcasting special "prohibited" information. For example, if the current cell does not want the high-speed terminal to camp here, the base station can broadcast the prohibition information for the high-speed mobile terminal, so that the high-speed terminal does not reside in the current cell after reading the forbidden information for the high-speed terminal. Terminals that are in other motion states or that do not have a motion state will not be affected even if this message is read.

具体来讲，在 LTE-A***里，基站可以在 SIB1 广播消息中加入针对高速终端的禁止信息（Cell Barred High ) 。这个禁止信息只针对高速终端，对其他运动状态或没有判断运动状态的终端不起作用。当然，对高速终端而言，是否禁止驻留在当前小区将同时参考 Cell Barred High和 /或其他的限制信息。 Specifically, in the LTE-A system, the base station can add a prohibition message for the high-speed terminal (Cell Barred High) to the SIB1 broadcast message. This prohibition message is only for the high-speed terminal and does not work for other motion states or terminals that do not have a motion state. Of course, for high-speed terminals, it is forbidden to camp on the current cell and refer to Cell Barred High and/or other restrictions.

相似的，如果当前小区不希望中速或低速终端驻留在当前小区，也可以广播针对于中速或低速终端的 "禁止" 信息。这样中速或低速终端在读到针对中速或低速终端的 "禁止" 信息后就可能（因为可能还需要参考其他信息）不会驻留在当前小区了，而其他运动状态或没有判断运动状态的终端即便读到这个 "禁止" 信息也不会受到任何影响。其具体通知过程与通知高速终端禁止信息的过程类似。 Similarly, if the current cell does not want the medium or low speed terminal to camp on the current cell, it can also broadcast "prohibited" information for the medium or low speed terminal. Such a medium or low speed terminal may be able to read the "prohibited" information for the medium or low speed terminal (because it may need to refer to other information), it will not reside in the current cell, and other motion states may not determine the motion state. The terminal will not be affected even if it reads this "prohibited" message. The specific notification process is similar to the process of notifying the high-speed terminal to prohibit information.

(二）小区重选优先级集合 (2) Cell reselection priority set

基站会向终端提供进行小区重选的频率列表，对于每个频率，可以提供其对应的重选优先级 (cell Reselection Priority)„ 终端可以在提供的频率上搜索相邻小区（包括高优先级频率上的相邻小区、同等优先级频率或同频小区、低优先级频率上的小区），并根据其频率的优先级来判断是否进行测量和应用相对应的小区重选准则。终端可以从广播消息或专用消息中得到频率列表及其优先级，也可以按照某些预设准则推断出其优先级，其中，广播消息中的优先级会发送至小区中的所有终端，而专用消息中的优先级则只会发送至特定的终端（并且这个优先级只在一定的时间段内有效）。 The base station provides the terminal with a frequency list for cell reselection. For each frequency, its corresponding reselection priority (cell Reselection Priority) can be provided. „ The terminal can search for neighboring cells on the provided frequency (including high priority frequencies). The neighboring cell, the same priority frequency or the same frequency cell, the cell on the low priority frequency, and judge whether to perform measurement and apply the corresponding cell reselection criterion according to the priority of the frequency. The terminal can broadcast from the broadcast. Message or private message Obtaining the frequency list and its priority, and inferring its priority according to some preset criteria, wherein the priority in the broadcast message is sent to all terminals in the cell, and the priority in the dedicated message is only sent To a specific terminal (and this priority is only valid for a certain period of time).

终端在根据频率列表对搜索到的相邻小区进行测量时，如果当前的服务小区信号质量足够好（即满足一定条件），可以不去测量同等优先级或低优先级频率上相邻小区。但是在任何情况下，终端必须要测量搜索到的高优先级频率上的相邻小区，因此，可以通过在小区重选优先级集合中指定小区的重选优先级，就可能控制终端的小区重选结果。 When the terminal measures the neighboring cell that is searched according to the frequency list, if the current serving cell signal quality is good enough (that is, a certain condition is met), the adjacent cell on the same priority or low priority frequency may not be measured. However, in any case, the terminal must measure the neighboring cell on the searched high priority frequency. Therefore, it is possible to control the cell weight of the terminal by specifying the cell reselection priority in the cell reselection priority set. Choose the result.

具体地，对同一个频率，基站可以向处于不同移动状态的终端通知不同的重选优先级。比如当前***中的宏小区层采用频率 F1 , 而小小区层采用频率 F2 , 为了达到让高速终端驻留在宏小区层的目的，可以这样设置：对于高速终端， F1 的重选优先级高于 F2 的重选优先级（比如，优先级的数字越大，级别越高）；同时，对于其他运动状态或没有判断运动状态的终端来讲， F1 的重选优先级低于 F2的重选优先级。这样，高速终端就更趋于重选并驻留在宏小区层，而其他运动装态或没有判断运动状态的终端就趋于重选并驻留在小小区层。 Specifically, for the same frequency, the base station can notify different terminals of different mobile states of different reselection priorities. For example, in the current system, the macro cell layer uses the frequency F1, and the small cell layer uses the frequency F2. In order to achieve the purpose of allowing the high-speed terminal to reside in the macro cell layer, it can be set as follows: For the high-speed terminal, the F1 reselection priority is higher than F2 reselection priority (for example, the higher the priority number, the higher the level); At the same time, for other sports states or terminals that do not judge the motion state, F1's reselection priority is lower than F2's reselection priority. level. In this way, the high-speed terminal tends to reselect and reside at the macro cell layer, while other mobile or non-determined motion states tend to reselect and reside in the small cell layer.

具体通知时，这个通知过程可以通过单播和 /或广播消息来实现，比如在 LTE-A***中，可以在 RRC Connection Release单播消息中，和 /或 SIB3 (用于广播同频小区的重选参数）和 SIB5 (用于广播异频小区的重选参数）广播消息中，通知所有终端某个频率对应的针对高速终端的 cell Reselection Priority High和针对其他运动状态和没有判断运动速度终端的 cell Reselection Priority。通过对不同频率设置 cell Reselection Priority High, 可以达到让 F1 的重选优先级高于 F2 的重选优先级的目的；而在 cell Reselection Priority中，可以设定 F1的重选优先级低于 F2的重选优先级。 For specific notification, this notification process can be implemented by unicast and/or broadcast messages, for example, in the LTE-A system, in the RRC Connection Release unicast message, and/or SIB3 (for broadcasting the same frequency cell) Selecting parameters) and SIB5 (reselection parameters for broadcasting inter-frequency cells) broadcast messages, notifying all terminals of a certain frequency corresponding to the high-speed terminal cell Reselection Priority High and for other motion states and cells without determining the motion speed terminal Reselection Priority. By setting the cell Reselection Priority High for different frequencies, the purpose of making the reselection priority of F1 higher than the reselection priority of F2 can be achieved; in the cell Reselection Priority, the reselection priority of F1 can be set lower than F2. Reselect priority.

相似的，如果为了达到让中速或低速终端驻留在小小区层的目的，基站可以通知终端：对于中速或氏速终端， F1 的重选优先级氏于 F2的重选优先级；同时，对于其他状态或没有判断运动状态的终端来讲， F1 的重选优先级高于 F2 的重选优先级。这样，就可以达到让中速或低速终端趋向于驻留在小小区、而其他状态终端或没有判断终端状态的终端驻留在宏小区层的目的。其具体通知过程与上文所述过程类似。 Similarly, if the purpose of allowing the medium or low speed terminal to camp on the small cell layer, the base station can notify the terminal: For the medium speed or fast speed terminal, the reselection priority of F1 is the reselection priority of F2; For other terminals or terminals that do not judge the motion state, the weight of F1 Select a reselection priority with a priority higher than F2. In this way, it is possible to achieve the purpose that the medium-speed or low-speed terminal tends to reside in the small cell, and the other state terminal or the terminal that does not judge the terminal state resides in the macro cell layer. The specific notification process is similar to the process described above.

(三）小区重选频率集合 (3) Cell reselection frequency set

小区重选频率集合中包含指定类型的小区所在的频率或所述指定类型的小区所不在的频率，从而由终端根据该小区重选频率集合确定小区重选的对象，并最终重选至所述指定类型的小区。 The frequency of the cell reselection frequency includes the frequency of the cell of the specified type or the frequency of the cell of the specified type, so that the terminal determines the object of cell reselection according to the cell reselection frequency set, and finally reselects to the A cell of the specified type.

第一种方式，即小区重选频率集合中包含指定类型的小区所在的频率，下面列举其中三种具体的实施方式： The first mode, that is, the frequency of the cell of the specified type is included in the cell reselection frequency set, and three specific implementation modes are listed below:

1 ) 、假定高速终端重选至宏小区层所在的频率，则基站给高速终端的小区重选集合中就不包括小小区层所在的频率。这个通知过程可以通过单播和 /或多播消息来实现。比如，宏小区层在频率 F1 , 而小小区层在频率 F2 , 那么基站在通知终端时，对于高速终端，其小区重选频率集合中包括 F1 而不包括 F2 , 而对于其他状态终端或者没有判断状态终端，其小区重选频率集合中则包括 F2。这样高速终端就不会将小小区作为重选对象，也就不会驻留在小小区层，而其他终端则可以重选驻留在小小区层。 1) Assuming that the high-speed terminal reselects to the frequency at which the macro cell layer is located, the base station does not include the frequency at which the small cell layer is located in the cell reselection set of the high-speed terminal. This notification process can be implemented by unicast and/or multicast messages. For example, if the macro cell layer is at the frequency F1 and the small cell layer is at the frequency F2, then when the base station notifies the terminal, for the high-speed terminal, the cell reselection frequency set includes F1 instead of F2, and the other state terminal does not have a judgment. The status terminal includes F2 in its cell reselection frequency set. In this way, the high-speed terminal does not use the small cell as the reselection object, and does not reside in the small cell layer, while other terminals can reselect to reside in the small cell layer.

具体通知时，比如在 LTE-A ***中，基站在通知终端时，可以在 RRC Connection Release 单播消息中通知终端针对高速状态时的小区重选集合（不包括 F2 ) 和针对其他状态和没有判断状态的小区重选频率集合 (包括 F2 ) 。除了单播消息，也可以采用广播消息，比如在宏小区的 SIB5 广播消息中，提供两个重选频率集合：针对高速终端的小区重选频率集合不包括 F2 , 而针对其他运动状态和没有判断运动状态的终端的小区重选频率集合中包括 F2。通过上述方案，则对于此时驻留在 F1 上但是其运动状态为高速的终端，重选时应该不再考虑 F2, 从而驻留到 F1 对应的宏小区层。 For specific notification, for example, in the LTE-A system, when the base station notifies the terminal, the base station can notify the terminal in the RRC Connection Release unicast message that the terminal reselects the set for the high-speed state (excluding F2) and does not judge for other states. The state of the cell reselection frequency set (including F2). In addition to the unicast message, a broadcast message may also be used, for example, in the SIB5 broadcast message of the macro cell, two reselection frequency sets are provided: the cell reselection frequency set for the high speed terminal does not include F2, and the other motion states are not judged. F2 is included in the cell reselection frequency set of the terminal in the motion state. With the above scheme, for a terminal that resides on F1 at this time but whose motion state is high speed, F2 should no longer be considered in reselection, thereby camping on the macro cell layer corresponding to F1.

相似的，如果***希望中速或低速终端驻留在小小区层，那么基站提供给中速或低速终端的小区重选频率集合中就不包括宏小区层所在的频率。具体通知时，仍以 LTE-A***为例，可以在 RRC Connection Release 单播消息中通知终端针对中速或低速终端的小区重选频率集合（不包括 Fl ) 和针对其他状态或没有判断状态的终端的小区重选频率集合（包括 F1 ) 。而对于广播的形式，可以在小小区的 SIB5 广播消息中，提供两个小区重选频率集合：针对中速或低速终端的小区重选频率集合（不包括 F1 ) 和针对其他运动状态或没有判断运动状态的小区重选频率集合中（包括 F1 ) 。通过上述方案，则对于此时驻留在 F2上但是其运动状态为中速或低速的终端，重选时应该不再考虑 Fl。 Similarly, if the system wants the medium-speed or low-speed terminal to camp on the small cell layer, the frequency of the cell reselection frequency set provided by the base station to the medium-speed or low-speed terminal does not include the frequency at which the macro cell layer is located. For the specific notification, the LTE-A system is still used as an example, and the terminal may be notified of the cell reselection frequency set for the medium or low speed terminal in the RRC Connection Release unicast message (excluding Fl) and a cell reselection frequency set (including F1) for terminals of other states or without judgment states. For the broadcast form, two cell reselection frequency sets may be provided in the SIB5 broadcast message of the small cell: a cell reselection frequency set for the medium or low speed terminal (excluding F1) and for other motion states or no judgment The cell reselection frequency set in the motion state (including F1). With the above scheme, for terminals that residing on F2 at this time but whose motion state is medium or low speed, Fl should no longer be considered in reselection.

2 ) 、基站给高速终端的小区重选集合中包括宏小区层和小小区层所在的频率，其中，在宏小区层对应的频率上添加有选择标识，这个标识可以通知高速终端可以选择标识对应的频率。这个通知过程可以通过单播和 /或多播消息来实现。比如，宏小区层在频率 F1 , 而小小区层在频率 F2 , 那么基站在通知终端时，对于高速终端，其小区重选频率集合中包括 F1 和 F2 , 但 F1 上存在选择标识，这个标识可以通知高速终端可以选择标识对应的频率；而对于其他状态终端，其小区重选频率集合中也包括 F1 和 F2 , 但 F2 上存在选择标识，这个标识可以通知其他状态终端可以选择标识对应的频率；而对于没有判断状态终端，其小区重选集合中则包括未添加标识的 F1和 F2。这样高速终端就可以选择具有选择标识的 Fl , 从而不会将小小区作为重选对象，也就不会驻留在小小区层，而其他终端则可以重选驻留在小小区层。 2), the cell reselection set of the high-speed terminal includes a frequency at which the macro cell layer and the small cell layer are located, where the selection identifier is added to the frequency corresponding to the macro cell layer, and the identifier can notify the high-speed terminal that the identifier can be selected. Frequency of. This notification process can be implemented by unicast and/or multicast messages. For example, if the macro cell layer is at the frequency F1 and the small cell layer is at the frequency F2, then when the base station informs the terminal, for the high-speed terminal, the cell reselection frequency set includes F1 and F2, but the F1 has a selection identifier, and the identifier may be The high-speed terminal can be configured to select the corresponding frequency; and for other state terminals, the cell reselection frequency set also includes F1 and F2, but there is a selection identifier on the F2, and the identifier can notify other state terminals to select the corresponding frequency; For the terminal without judgment status, the cell reselection set includes F1 and F2 with no added identifier. In this way, the high-speed terminal can select the F1 with the selected identifier, and the small cell is not used as the reselection object, and therefore does not reside in the small cell layer, and other terminals can be reselected to reside in the small cell layer.

相似的，如果***希望中速或低速终端驻留在小小区层，那么基站给中速或低速终端的小区重选集合中包括宏小区层和小小区层所在的频率，其中，在小小区层对应的频率上添加有选择标识。 Similarly, if the system wants the medium-speed or low-speed terminal to reside in the small cell layer, the base station selects the frequency of the macro cell layer and the small cell layer in the cell reselection set of the medium-speed or low-speed terminal, where the small cell layer A selection identifier is added to the corresponding frequency.

3 ) 、基站给高速终端的小区重选集合中包括宏小区层和小小区层所在的频率，还包括选择消息，以用于指示终端对于频率的选择操作。这个通知过程可以通过单播和 /或多播消息来实现。比如，宏小区层在频率 F1 , 而小小区层在频率 F2 , 那么基站在通知终端时，对于高速终端，其小区重选频率集合中包括 F1 和 F2 , 以及对 F1 的选择消息；而对于其他状态终端，其小区重选频率集合中也包括 F1 和 F2, 以及对 F2 的选择消息；而对于没有判断状态终端，其小区重选集合中则仅包括 F1 和 F2。这样高速终端就可以根据选择消息选中 F1 , 从而不会将小小区作为重选对象，也就不会驻留在小小区层，而其他终端则可以重选驻留在小小区层。具体通知时，比如在宏小区的 SIB3 广播消息中，提供相关的选择消息：对于正驻留在当前服务小区的高速终端，其在重选时需要考虑当前服务小区的频率 F1 ; 而对于其他运动状态和没有判断运动状态的终端，提供相关的忽略消息，提示其在重选时需要忽略当前服务小区的频率 Fl。这样，对于此时驻留在 F1 上且其运动状态为高速的终端，重选时应该考虑 Fl。再比如在小小区的 SIB3广播消息中，提供相关的选择消息：对于正驻留在当前服务小区的中速或低速终端，其在重选时需要考虑当前服务小区的频率 F2; 而对于其他运动状态和没有判断运动状态的终端，提供相关的忽略消息，提示其在重选时需要忽略当前服务小区的频率 F2。这样，对于此时驻留在 F2 上但是其运动状态为高速的终端，重选是应该也不再考虑 F2。 3) The frequency of the macro cell layer and the small cell layer in the cell reselection set of the high-speed terminal, and the selection message is further included to indicate the terminal selection operation for the frequency. This notification process can be implemented by unicast and/or multicast messages. For example, if the macro cell layer is at frequency F1 and the small cell layer is at frequency F2, then when the base station informs the terminal, for the high speed terminal, the cell reselection frequency set includes F1 and F2, and the selection message for F1; The status terminal also includes F1 and F2 in the cell reselection frequency set, and a selection message for F2. For the terminal without judgment status, only the F1 and F2 are included in the cell reselection set. In this way, the high-speed terminal can select F1 according to the selection message, so that the small cell is not used as the reselection pair. Like, it will not reside in the small cell layer, while other terminals can reselect to reside in the small cell layer. For specific notification, for example, in the SIB3 broadcast message of the macro cell, the relevant selection message is provided: For the high-speed terminal that is camping on the current serving cell, it needs to consider the frequency F1 of the current serving cell during reselection; The terminal and the terminal that does not judge the motion state provide related ignore messages, prompting them to ignore the frequency Fl of the current serving cell during reselection. Thus, for a terminal that resides on F1 at this time and whose motion state is high, Fl should be considered in reselection. For example, in the SIB3 broadcast message of the small cell, the related selection message is provided: For the medium-speed or low-speed terminal that is camping on the current serving cell, it needs to consider the frequency F2 of the current serving cell when reselecting; The terminal and the terminal that does not determine the motion state provide related ignore messages, prompting them to ignore the frequency F2 of the current serving cell during reselection. Thus, for a terminal that resides on F2 at this time but whose motion state is high, reselection should no longer consider F2.

相似的，如果***希望中速或低速终端驻留在小小区层，那么基站给中速或低速终端的小区重选集合中包括宏小区层和小小区层所在的频率，还包括针对小小区层的选择消息，以用于指示中速或低速终端选择小小区层。 Similarly, if the system wants the medium-speed or low-speed terminal to reside in the small cell layer, the base station includes the frequency of the macro cell layer and the small cell layer in the cell reselection set of the medium-speed or low-speed terminal, and includes the small cell layer. The selection message is used to indicate that the medium or low speed terminal selects the small cell layer.

第二种方式，即小区重选频率集合中包含指定类型的小区所不在的频率，则此时可以通过多种方式来指定 "所不在的频率" ，下面列举其中两种具体的实施方式： In the second method, that is, the frequency of the cell of the cell reselection includes the frequency of the cell of the specified type, the "frequency that is not present" can be specified in multiple manners. Two specific implementation modes are listed below:

1 ) 、基站给高速终端的小区重选集合中包括宏小区层和小小区层所在的频率，其中，在小小区层对应的频率上添加有忽略标识。这个通知过程可以通过单播和 /或多播消息来实现。比如，宏小区层在频率 F1 , 而小小区层在频率 F2 , 那么基站在通知终端时，对于高速终端，其小区重选频率集合中包括 F1 和 F2, 但 F2上存在适用于高速终端的忽略标识，而对于其他状态终端，其小区重选频率集合中也包括 F1 和 F2, 但 F1 上存在适用于其他状态终端的忽略标识，而对于没有判断状态终端，其小区重选集合中则包括未添加标识的 F1 和 F2。这样高速终端就可以忽略具有忽略标识的 F2 , 从而不会将小小区作为重选对象，也就不会驻留在小小区层，而其他终端则可以重选驻留在小小区层。相似的，如果***希望中速或低速终端驻留在小小区层，那么基站给中速或低速终端的小区重选集合中包括宏小区层和小小区层所在的频率，其中，在宏小区层对应的频率上添加有忽略标识。 1) The base station in the cell reselection set of the high-speed terminal includes a frequency at which the macro cell layer and the small cell layer are located, where the ignore identifier is added to the frequency corresponding to the small cell layer. This notification process can be implemented by unicast and/or multicast messages. For example, if the macro cell layer is at the frequency F1 and the small cell layer is at the frequency F2, then when the base station informs the terminal, for the high-speed terminal, the cell reselection frequency set includes F1 and F2, but there is an ignorance for the high-speed terminal on the F2. Identification, and for other state terminals, the cell reselection frequency set also includes F1 and F2, but there is an ignore identifier applicable to other state terminals on F1, and for the cell without re-determination status, the cell reselection set includes Add the identified F1 and F2. In this way, the high-speed terminal can ignore the F2 with the ignore flag, so that the small cell is not used as the reselection object, and therefore does not reside in the small cell layer, and other terminals can be reselected to reside in the small cell layer. Similarly, if the system wants the medium-speed or low-speed terminal to reside in the small cell layer, the base station selects the frequency of the macro cell layer and the small cell layer in the cell reselection set of the medium-speed or low-speed terminal, where the macro cell layer An ignore flag is added to the corresponding frequency.

2 ) 、基站给高速终端的小区重选集合中包括宏小区层和小小区层所在的频率，还包括忽略消息，以用于指示终端对于频率的忽略操作。这个通知过程可以通过单播和 /或多播消息来实现。比如，宏小区层在频率 F1 , 而小小区层在频率 F2 , 那么基站在通知终端时，对于高速终端，其小区重选频率集合中包括 F1 和 F2 , 以及对 F2 的忽略消息；而对于其他状态终端，其小区重选频率集合中也包括 F1 和 F2, 以及对 F1 的忽略消息；而对于没有判断状态终端，其小区重选集合中则仅包括 F1 和 F2。这样高速终端就可以根据忽略消息选中 F2 , 从而不会将小小区作为重选对象，也就不会驻留在小小区层，而其他终端则可以重选驻留在小小区层。 2) The frequency of the macro cell layer and the small cell layer included in the cell reselection set of the high-speed terminal by the base station, and the ignoring message is used to indicate that the terminal ignores the frequency. This notification process can be implemented by unicast and/or multicast messages. For example, if the macro cell layer is at frequency F1 and the small cell layer is at frequency F2, then when the base station informs the terminal, for the high speed terminal, the cell reselection frequency set includes F1 and F2, and the ignore message for F2; The status terminal also includes F1 and F2 in the cell reselection frequency set, and an ignoring message for F1. For the terminal without judgment status, only the F1 and F2 are included in the cell reselection set. Such a high-speed terminal can select F2 according to the ignore message, so that the small cell is not used as the reselected object, and therefore does not reside in the small cell layer, and other terminals can be reselected to reside in the small cell layer.

具体通知时，比如在小小区的 SIB3 广播消息中，提供相关的忽略消息：对于正驻留在当前服务小区的高速终端，提示其在重选时需要忽略当前服务小区的频率 F2 ; 而对于其他运动状态和没有判断运动状态的终端，提供相关的选择消息，其在重选时需要考虑当前服务小区的频率 F2。这样，对于此时驻留在 F2 上但是其运动状态为高速的终端，重选是应该也不再考虑 F2。再比如在宏小区的 SIB3 广播消息中，提供相关的忽略消息：对于正驻留在当前服务小区的中速或低速终端，提示其在重选时需要忽略当前服务小区的频率 F1 ; 而对于其他运动状态和没有判断运动状态的终端，提供相关的选择消息，其在重选时时需要考虑当前服务小区的频率 Fl。这样，对于此时驻留在 F2 上但是其运动状态为中速或低速的终端，重选是应该也不再考虑 Fl。 For specific notification, for example, in the SIB3 broadcast message of the small cell, the related ignore message is provided: For the high-speed terminal that is camping on the current serving cell, it is prompted to ignore the frequency F2 of the current serving cell during reselection; The motion state and the terminal that does not determine the motion state provide related selection messages, which need to consider the frequency F2 of the current serving cell when reselecting. Thus, for a terminal that resides on F2 at this time but whose motion state is high, reselection should no longer consider F2. For example, in the SIB3 broadcast message of the macro cell, the related ignore message is provided: For the medium or low speed terminal that is camping on the current serving cell, it is prompted to ignore the frequency F1 of the current serving cell during reselection; The motion state and the terminal that does not determine the motion state provide related selection messages, which need to consider the frequency F1 of the current serving cell when reselecting. Thus, for a terminal that resides on F2 at this time but whose motion state is medium or low, reselection should no longer consider Fl.

相似的，如果***希望中速或低速终端驻留在小小区层，那么基站给中速或低速终端的小区重选集合中包括宏小区层和小小区层所在的频率，还包括针对小小区层的选择消息和 /或针对宏小区层的忽略消息，以用于指示中速或低速终端选择小小区层和 /或忽略宏小区层。 Similarly, if the system wants the medium-speed or low-speed terminal to reside in the small cell layer, the base station includes the frequency of the macro cell layer and the small cell layer in the cell reselection set of the medium-speed or low-speed terminal, and includes the small cell layer. The selection message and/or the ignore message for the macro cell layer is used to indicate that the medium or low speed terminal selects the small cell layer and/or ignores the macro cell layer.

(四）小区重选时间集合 (iv) Cell reselection time collection

终端在重选至某个小区时，该小区的信号强度或质量必须强于预设的数值、并且能够连续保持预设的时间段，比如对于某个衡量信号好坏的变量为 r, 设定当 r大于或不小于 m的时间持续 n秒时，才允许终端重选至对应的小区，此时设定的 "n 秒" 即为小区重选时间 T_reselecti。_n。因此，当某个小区的小区重选时间较之其他小区更短时，相当于对该小区的重选要求更低，则终端相对而言更容易重选至该小区。 When the terminal is reselected to a certain cell, the signal strength or quality of the cell must be stronger than the preset The value is, and can be continuously maintained for a preset period of time, for example, for a variable that measures the quality of the signal is r, and the terminal is allowed to reselect to the corresponding cell when the time of r is greater than or not less than m for n seconds. The "n seconds" set at this time is the cell reselection time T _reselecti . _n . Therefore, when the cell reselection time of a certain cell is shorter than other cells, which is equivalent to lower reselection requirements for the cell, the terminal is relatively easier to reselect to the cell.

具体地，可以针对不同运动状态的终端，在执行小区重选时，对同一频率应用不同的小区重选时间。比如要避免高速终端驻留在小小区层，那么对高速终端来讲，其小小区所在频率对应的小区重选时间应该要长于其他运动状态或者没有判断运动状态的终端所应用的小区重选时间，且对于高速终端自身而言，小小区所在频率对应的小区重选时间应该长于宏小区所在频率对应的小区重选时间。基站可以通过单播或广播消息来通知终端不同状态所对应的不同小区重选时间。 Specifically, different cell reselection times may be applied to the same frequency when performing cell reselection for terminals of different motion states. For example, to avoid the high-speed terminal camping on the small cell layer, for the high-speed terminal, the cell reselection time corresponding to the frequency of the small cell should be longer than other mobile states or the cell reselection time applied by the terminal without determining the motion state. For the high-speed terminal itself, the cell reselection time corresponding to the frequency of the small cell should be longer than the cell reselection time corresponding to the frequency of the macro cell. The base station can notify the different cell reselection time corresponding to different states by using a unicast or broadcast message.

具体通知时，比如在 LTE-A ***中，支定宏小区层在频率 F1 , 而小小区层在频率 F2。那么，在宏小区的 SIB5 中，基站会广播两个针对 F2 的小区重选时间：针对高速终端的小区重选时间和其他终端的小区重选时间，前者要长于后者，并且对于高速终端而言，其针对 F1 的小区重选时间要小于针对 F2的小区重选时间；而在小小区的 SIB3中，基站会广播两个针对 F2 的小区重选时间：针对高速终端的小区重选时间和针对其他终端的小区重选时间，前者要长于后者，并且对于高速终端而言，其针对 F1 的小区重选时间要小于针对 F2的小区重选时间。通过这种方式，高速终端重选到小小区层的时间会更长，降低了重选到小小区层的概率，使高速终端尽可能重选至宏小区层。 For specific notification, for example, in the LTE-A system, the macro cell layer is at frequency F1 and the small cell layer is at frequency F2. Then, in the SIB5 of the macro cell, the base station broadcasts two cell reselection times for F2: the cell reselection time for the high speed terminal and the cell reselection time of other terminals, the former is longer than the latter, and for the high speed terminal In other words, the cell reselection time for F1 is smaller than the cell reselection time for F2; in SIB3 of the small cell, the base station broadcasts two cell reselection times for F2: cell reselection time for high speed terminal and For the cell reselection time of other terminals, the former is longer than the latter, and for high speed terminals, the cell reselection time for F1 is smaller than the cell reselection time for F2. In this way, the time for the high-speed terminal to reselect to the small cell layer is longer, the probability of reselection to the small cell layer is reduced, and the high-speed terminal is reselected to the macro cell layer as much as possible.

相似的，如果要避免中速或低速终端驻留在宏小区层，那么其处理方法与对高速终端的处理方法类似，即当宏小区层在频率 F1 , 而小小区层在频率 F2时，则针对中速或低速终端， F1对应的小区重选时间要长于 F2 对应的小区重选时间。 Similarly, if the medium-speed or low-speed terminal is to be camped on the macro cell layer, the processing method is similar to that of the high-speed terminal, that is, when the macro cell layer is at the frequency F1 and the small cell layer is at the frequency F2, For medium or low speed terminals, the cell reselection time corresponding to F1 is longer than the cell reselection time corresponding to F2.

(五）重选准则门限值集合 (5) Re-election criteria threshold set

如果相邻小区的测量结果满足一定小区重选准则，终端就可以重选到满足条件的相邻小区中优先级最高的那个小区。具体如下： 1、对于在较高优先级频率上的相邻小区，如果***配置了服务小区低质量门限（ Thresh_Serving, _L。_WQ ) , 那么，如果相邻小区的质量在其频率对应的小区重选时间内优于高优先级质量门限（Thresh_x, _HighQ ) , 并且终端已经在当前服务小区驻留时间超过 1秒，那么，终端就可以重选到这个小区；如果***没有配置服务小区低质量门限，那么，如果相邻小区的信号强度在其频率对应的小区重选时间内优于高优先级强度门限（ Thresh_x, HighP ) , 并且终端已经在当前服务小区驻留超过 1 秒，那么，终端就可以重选到这个小区。 If the measurement result of the neighboring cell satisfies a certain cell reselection criterion, the terminal can reselect the cell with the highest priority among the neighboring cells satisfying the condition. details as follows: 1. For a neighboring cell on a higher priority frequency, if the system configures a serving cell low quality threshold (Thesh _Serving , _L. _W Q ), then if the quality of the neighboring cell is reselected in the cell corresponding to its frequency The time is better than the high priority quality threshold (Thresh _x , _HighQ ), and the terminal has been in the current serving cell for more than 1 second, then the terminal can reselect to the cell; if the system does not configure the serving cell low quality threshold Then, if the signal strength of the neighboring cell is better than the high priority strength threshold (Thesh _x , HighP ) in the cell reselection time corresponding to the frequency, and the terminal has camped in the current serving cell for more than 1 second, then the terminal You can re-select to this community.

2、对于同等优先级频率上的或同频小区，如果在小区重选时间段内，相邻小区的测量结果按照排序准则优于服务小区，并且终端已经在当前服务小区驻留超过 1秒，那么，终端就可以重选到这个小区。 2. For the same priority frequency or the same frequency cell, if the measurement result of the neighboring cell is better than the serving cell according to the ranking criterion in the cell reselection time period, and the terminal has camped in the current serving cell for more than 1 second, Then, the terminal can reselect to this cell.

3、对于在较低优先级频率上的相邻小区，如果***配置了服务小区低质量门限，那么，在其频率对应的小区重选时间内，如果服务小区的质量低于服务小区低质量门限，同时，相邻小区测量出的质量优于低优先级质量门限（ Thresh_x, _L。_WQ ) , 并且终端已经在当前服务小区驻留超过 1 秒，那么，终端就可以重选到这个小区；如果***没有配置服务小区低质量门限，那么，在相邻小区所在频率对应的小区重选时间内，如果服务小区的信号强度低于服务小区强度门限（Thresh_Serving, _L。_wP ) , 同时，相邻小区测量出的信号强度优于低优先级强度门限（Thresh_x, _L。_wP ) , 并且终端已经在当前服务小区驻留超过 1秒，那么，终端就可以重选到这个小区。 3. For a neighboring cell on a lower priority frequency, if the system configures a low quality threshold of the serving cell, if the quality of the serving cell is lower than the low quality threshold of the serving cell in the cell reselection time corresponding to its frequency At the same time, the quality measured by the neighboring cell is better than the low priority quality threshold (Thesh _x , _L. _W Q ), and the terminal has camped in the current serving cell for more than 1 second, then the terminal can reselect to the cell. If the system does not configure the low-quality threshold of the serving cell, then, in the cell reselection time corresponding to the frequency of the neighboring cell, if the signal strength of the serving cell is lower than the serving cell strength threshold (Thresh _Serving , _L. _wP ), The measured signal strength of the neighboring cell is better than the low priority strength threshold (Thresh _x , _L . _wP ), and the terminal has camped in the current serving cell for more than 1 second, then the terminal can reselect to the cell.

4、如果多个小区满足上述重选准则，那么终端应该重选到其中具有最高优先级的小区。 4. If multiple cells meet the above reselection criteria, the terminal should reselect the cell with the highest priority among them.

由于存在上述重选准则，针对不同运动状态的终端，在执行重选与当前频率不同优先级频率上的小区时，可以采用不同的重选准则门限值。具体地，假设***中宏小区层在 F1 , 小小区层在 F2 , 有两种情况： Due to the above-mentioned reselection criteria, different reselection criteria threshold values may be used for terminals in different motion states when performing reselection of cells on different priority frequencies with current frequencies. Specifically, assuming that the macro cell layer in the system is at F1 and the small cell layer is at F2, there are two cases:

情况 1 : F1的优先级高于 F2的优先级。 Case 1: F1 has a higher priority than F2.

情况 2: F2的优先级高于 F1的优先级。 Case 2: F2 has a higher priority than F1.

如果***希望高速终端趋向于选择宏小区层，那么门限值的处理如下：在情况 1下：宏小区基站通知小区中的高速终端比其他终端更低的服务小区门限值（比如对于高速终端，其服务小区门限值低于某个预设的门限值，而对于其他终端，其服务小区门限值等于该预设门限值），同时，对应于低于服务频率优先级的频率（此处为 F2 ) , 通知高速终端比其他终端更高的低优先级测量门限（比如对于高速终端，其低优先级测量门限高于某个预设的门限值，而对于其他终端，其低优先级测量门限等于该预设门限值）；而在小小区里，对应于高于服务频率优先级的频率（此处为 F1 ) , 通知高速终端比其他终端更低的高优先级测量门限（比如对于高速终端，其高优先级测量门限低于某个预设的门限值，而对于其他终端，其高优先级测量门限等于该预设门限值）。具体来讲，在 LTE-A***中：If the system wants the high speed terminal to tend to select the macro cell layer, then the threshold is processed as follows: In case 1: the macro cell base station notifies the high-speed terminal in the cell that the serving cell threshold is lower than other terminals (for example, for the high-speed terminal, the serving cell threshold is lower than a preset threshold, but The other terminal, whose serving cell threshold is equal to the preset threshold), and corresponding to the frequency lower than the priority of the serving frequency (here, F2), notifies the high-speed terminal of higher priority measurement than other terminals. Threshold (for example, for a high-speed terminal, the low-priority measurement threshold is higher than a preset threshold, and for other terminals, the low-priority measurement threshold is equal to the preset threshold); and in a small cell, Corresponding to a frequency higher than the priority of the service frequency (here, F1), notifying the high-speed terminal of a lower priority measurement threshold than other terminals (for example, for a high-speed terminal, the high-priority measurement threshold is lower than a preset Threshold, and for other terminals, the high priority measurement threshold is equal to the preset threshold). Specifically, in the LTE-A system:

( a ) 如果***设置了服务小区低质量门限（ Thresh_Serving, L。_WQ ) , 那么在宏小区的 SIB3 中，应当设置两个服务小区低质量门限： Thresh_Serving, L。WQ, High和 Thresh_Serving, _L。_WQ , 分别提供给高速终端和其他终端，并且前者小于后者。在宏小区 SIB5中，应该在 F2对应的信息中，设置两个低优先级质量门限： Thresh_x, _L。_WQ, _High和 Thresh_x, _L。_WQ , 分别提供给高速终端和其他终端，并且前者大于后者。这样，在 F1 中的高速用户会更难重选到 F2 上。 (A) If the system is set low mass serving cell threshold _{_{(Thresh Serving, L. W Q)}} , then the macro cell SIB3, it will be provided two low quality threshold serving cell: Thresh _Serving, L. WQ, High and Thresh _Serving , _L. _W Q is provided to the high speed terminal and other terminals, respectively, and the former is smaller than the latter. In the macro cell SIB5, two low priority quality thresholds should be set in the information corresponding to F2: Thresh _x , _L . _W Q, _High and Thresh _x , _L . _W Q is provided to the high speed terminal and other terminals, respectively, and the former is larger than the latter. This way, high-speed users in F1 will be more difficult to re-select on F2.

此外，在小小区的 SIB5中，还可以在 F1对应的信息中，设置两个高优先级质量门限： Thresh_x HighQ. High和 Threshx m_ghQ , 分别提供给高速终端和其他终端，并且前者小于后者。这样，在 F2 中的高速用户就会更加容易重选到 F1 上。 In addition, in the SIB5 of the small cell, two high priority quality thresholds may be set in the information corresponding to F1: Thresh _x HighQ. High and Threshx m _g hQ , respectively, for the high speed terminal and other terminals, and the former is smaller than the latter. This way, high-speed users in F2 will be more likely to re-select to F1.

( b ) 如果***没有设置服务小区低质量门限，那么在宏小区的 SIB3 中，应当设置两个服务小区低强度门限： Thresh_Serving, _LowP , _ffigh 和(b) If the system does not set the low-quality threshold of the serving cell, then in the SIB3 of the macro cell, two low-intensity thresholds of the serving cell should be set: Thresh _Serving , _LowP , _ffigh and

Threshservina, LowP，分别提供给高速终端和其他终端，并且前者小于后者。在宏小区 SIB5中，应该在 F2对应的信息中，设置两个低优先级强度门限 Thresh_x, _LowP, _High和 Thresh_x, _LowP分别提供给高速终端和其他终端，并且前者大于后者。这样，在 F1 中的高速用户会更难重选到 F2 上。同时，在小小区的 SIB5中，应该在 F1对应的信息中，设置两个高优先级强度门限 Thresh_x, _HighP, _High和 Thresh_x, _ffighP分别提供给高速终端和其他终端，并且前者小于后者。这样，在 F2中的高速用户就会更加容易重选到 Fl上。 Threshservina, LowP, are provided to high-speed terminals and other terminals, respectively, and the former is smaller than the latter. In the macro cell SIB5, two low priority strength thresholds Thresh _x , _LowP , _High and Thresh _x , _{LowP should} be set to the high speed terminal and other terminals respectively in the information corresponding to F2, and the former is larger than the latter. This way, high-speed users in F1 will be more difficult to re-select on F2. At the same time, in SIB5 of the small cell, two high priority intensity thresholds Thresh _x , _HighP , _High and Thresh _x , _{ffighP should} be set to the high speed terminal and other terminals respectively in the information corresponding to F1. Less than the latter. In this way, high-speed users in F2 will be more likely to re-select to Fl.

在情况 2 下：在宏小区里，对应于高于服务频率优先级的频率（此处为 F2 ) , 通知高速终端比其他终端更高的高优先级测量门限（比如对于高速终端，其高优先级测量门限高于某个预设的门限值，而对于其他终端，其高优先级测量门限等于该预设门限值）。在小小区中应当通知小区中的高速终端比其他终端更高的服务小区门限值（比如对于高速终端，其服务小区门限值高于某个预设的门限值，而对于其他终端，其服务小区门限值等于该预设门限值），同时，对应于低于服务频率优先级的频率（此处为 F 1 ) , 通知高速终端比其他终端更低的低优先级测量门限（比如对于高速终端，其低优先级测量门限低于某个预设的门限值，而对于其他终端，其低优先级测量门限等于该预设门限值）。具体来讲，在 LTE-A 系统中： In case 2: In the macro cell, corresponding to a frequency higher than the priority of the service frequency (here, F2), the high-speed terminal is notified of a higher priority measurement threshold than other terminals (for example, for high-speed terminals, its high priority) The level measurement threshold is higher than a preset threshold, and for other terminals, the high priority measurement threshold is equal to the preset threshold). In the small cell, the high-speed terminal in the cell should be notified of a higher serving cell threshold than other terminals (for example, for a high-speed terminal, the serving cell threshold is higher than a preset threshold, and for other terminals, The serving cell threshold is equal to the preset threshold), and corresponding to the frequency below the priority of the serving frequency (here, F 1 ), notifying the high-speed terminal of a lower priority measurement threshold than other terminals ( For example, for a high-speed terminal, the low-priority measurement threshold is lower than a preset threshold, and for other terminals, the low-priority measurement threshold is equal to the preset threshold. Specifically, in the LTE-A system:

( a ) 如果***设置了服务小区低质量门限（ Thresh_Serving, L。_WQ ) , 那么在宏小区的 SIB5中，应该在 F2对应的信息中，设置两个高优先级质量门限： Thresh_x HighQ . High和 Threshx m_ghQ , 分别提供给高速终端和其他终端，并且前者大于后者。这样，在 F1 中的高速用户会更难重选到 F2 上。 ( a ) If the system sets the Thresh _Serving (L. _W Q ) threshold, then in the SIB5 of the macro cell, two high priority quality thresholds should be set in the information corresponding to F2: Thresh _x HighQ High and Threshx m _g hQ are provided to the high speed terminal and other terminals, respectively, and the former is larger than the latter. This way, high-speed users in F1 will be more difficult to re-select on F2.

此外，在小小区的 SIB3 中，还可以设置两个服务小区低质量门限： Thresh_Serving, _LowQ, _High和 Thresh_Serving, _L。_wQ, 分别提供给高速终端和其他终端，并且前者大于后者。在小小区的 SIB5中，应该在 F1对应的信息中，设置两个低优先级质量门限： Thresh_x, _L。_WQ, _ffigh和 Thresh_x, _L。_WQ , 分别提供给高速终端和其他终端，并且前者小于后者。这样，在 F2 中的高速用户就会更加容易重选到 F1上。 In addition, in the SIB3 of the small cell, two low-quality thresholds of the serving cell can be set: Thresh _Serving , _LowQ , _High and Thresh _Serving , _L. _{wQ is} provided to the high speed terminal and other terminals respectively, and the former is larger than the latter. In the SIB5 of the small cell, two low priority quality thresholds should be set in the information corresponding to F1: Thresh _x , _L . _W Q, _ffigh and Thresh _x , _L . _W Q is provided to the high speed terminal and other terminals, respectively, and the former is smaller than the latter. This way, high-speed users in F2 will be more likely to re-select to F1.

( b ) 如果***没有设置服务小区低质量门限，那么在宏小区 SIB5 中 F2 对应的信息中，设置两个高优先级强度门限： Thresh_x, _HighP, _High和 Thresh_x, _HighP , 分别提供给高速终端和其他终端，并且前者大于后者。这样，在 F1中的高速用户会更难重选到 F2 上。 (b) If the system does not set the low-quality threshold of the serving cell, then in the information corresponding to F2 in the macro cell SIB5, two high-priority strength thresholds are set: Thresh _x , _HighP , _High and Thresh _x , _HighP , respectively for high speed Terminals and other terminals, and the former is larger than the latter. In this way, high-speed users in F1 will be more difficult to re-select to F2.

此外，在小小区的 SIB3 中，还可以设置两个服务小区低强度门限： Thresh_Serving, _L。_wp , High和 Thresh_Serving, _L。_wP , 分别提供给高速终端和其他终端，并且前者大于后者。在小小区 SIB5中，应该在 F1对应的信息中，设置两个低优先级强度门限： Thresh_x, _L。_wP, _ffigh和 Thresh_x, _L。_wP, 分别提供给高速终端和其他终端，并且前者小于后者。这样，在 F2 中的高速用户就会更加容易重选到 F1上。 In addition, in the SIB3 of the small cell, two low-intensity thresholds of the serving cell can also be set: Thresh _Serving , _L. _w p , High and Thresh _Serving , _L . _wP , respectively for high-speed terminals and other terminals End, and the former is larger than the latter. In the small cell SIB5, two low priority strength thresholds should be set in the information corresponding to F1: Thresh _x , _L . _wP , _ffigh and Thresh _x , _L . _{wP is} provided to the high speed terminal and other terminals respectively, and the former is smaller than the latter. This way, high-speed users in F2 will be more likely to re-select to F1.

相似的，如果让低速或中速终端尽量驻留在某一个小区层，可以采取与上述方法类似的过程，此处不再赘述。 Similarly, if the low-speed or medium-speed terminal is allowed to reside in a certain cell layer as much as possible, a process similar to the above method may be adopted, and details are not described herein again.

对应于图 3 所示的执行步骤，则相应基站的构成如图 4 所示。基站 400 包括：数据生成模块 402 , 用于生成对应于不同移动速度的小区重选参数；通知模块 404, 用于向终端通知所述小区重选参数，以由所述终端利用对应于自身移动速度的小区重选参数进行小区重选；其中，所述小区重选参数包括以下至少之一或其组合：禁止信息、小区重选优先级集合、小区重选频率集合、小区重选时间集合、重选准则门限值集合。在该技术方案中，通过采用本发明提出的小区重选参数中的任意一种或多种，并生成针对不同移动速度的小区重选参数，从而使终端能够利用与自身的移动速度相匹配的小区重选参数实现小区重选操作。由于终端的移动速度与小区重选参数相匹配，因而不同移动速度的终端重选到的小区类型也可能存在差异，比如使得高速终端尽可能重选至宏小区，从而减少终端的重选次数和避免进入连接状态后执行不必要的切换，降低终端的功耗开销。 Corresponding to the execution steps shown in Figure 3, the corresponding base station is constructed as shown in Figure 4. The base station 400 includes: a data generating module 402, configured to generate a cell reselection parameter corresponding to different mobile speeds; and a notification module 404, configured to notify the terminal of the cell reselection parameter, to use, by the terminal, a speed corresponding to the mobile terminal The cell reselection parameter performs cell reselection; wherein, the cell reselection parameter includes at least one of the following or a combination thereof: forbidden information, cell reselection priority set, cell reselection frequency set, cell reselection time set, weight Select the criteria threshold set. In this technical solution, by using any one or more of the cell reselection parameters proposed by the present invention, and generating cell reselection parameters for different moving speeds, the terminal can utilize the matching speed of the mobile terminal. The cell reselection parameter implements a cell reselection operation. Since the moving speed of the terminal matches the cell reselection parameter, the cell type reselected by the terminal with different moving speeds may also be different, for example, the high speed terminal is reselected to the macro cell as much as possible, thereby reducing the number of reselection times of the terminal and Avoid unnecessary switching after entering the connection state, reducing the power consumption overhead of the terminal.

相对于图 3和图 4所示的基站侧的处理流程和基站构成，对于终端而言，如图 5所示，其根据获取的小区重选参数进行小区重选的流程包括：步骤 502 , 获取自身的移动速度。 With respect to the processing flow of the base station side and the base station configuration shown in FIG. 3 and FIG. 4, for the terminal, as shown in FIG. 5, the process of performing cell reselection according to the acquired cell reselection parameter includes: Step 502: Acquire The speed of its own movement.

步骤 504, 接收来自基站的对应于不同移动速度的小区重选参数，并利用对应于自身移动速度的小区重选参数进行小区重选；其中，所述小区重选参数包括以下至少之一或其组合：禁止信息、小区重选优先级集合、小区重选频率集合、小区重选时间集合、重选准则门限值集合。 Step 504: Receive cell reselection parameters corresponding to different mobile speeds from the base station, and perform cell reselection by using a cell reselection parameter corresponding to the mobile speed. The cell reselection parameter includes at least one of the following or Combination: Prohibition information, cell reselection priority set, cell reselection frequency set, cell reselection time set, reselection criteria threshold set.

在该技术方案中，通过采用本发明提出的小区重选参数中的任意一种或多种，并生成针对不同移动速度的小区重选参数，从而使终端能够利用与自身的移动速度相匹配的小区重选参数实现小区重选操作。由于终端的移动速度与小区重选参数相匹配，因而不同移动速度的终端重选到的小区类型也可能存在差异，比如使得高速终端尽可能重选至宏小区，从而减少终端的重选次数和避免进入连接状态后执行不必要的切换，降低终端的功耗开销。 In this technical solution, by using any one or more of the cell reselection parameters proposed by the present invention, and generating cell reselection parameters for different moving speeds, the terminal can utilize the matching speed of the mobile terminal. The cell reselection parameter implements a cell reselection operation.

图 7是图 2所示实施例的***的框图。 Figure 7 is a block diagram of the system of the embodiment of Figure 2.

如图 7所示，该实施例还提出了一种*** 700, 包括如图 4所示的基站 400 , 以及如图 6所示的终端 600。实施例二 As shown in FIG. 7, this embodiment also proposes a system 700 including a base station 400 as shown in FIG. 4 and a terminal 600 as shown in FIG. Embodiment 2

图 8示出了根据本发明的另一个实施例的终端根据小区重选参数进行小区重选的示意图。 FIG. 8 is a diagram showing a cell performing cell reselection according to a cell reselection parameter according to another embodiment of the present invention.

如图 8所示，在根据本发明的另一个实施例中，主要是针对小区重选参数为小区重选频率集合的情况。 As shown in Fig. 8, in another embodiment in accordance with the present invention, it is mainly for the case where the cell reselection parameter is a cell reselection frequency set.

具体地，在图 2所示的实施例一中，基站 202将针对不同移动速度的终端生成对应的多种小区重选参数（如高速终端参数、中速终端参数、低速终端参数等）；而在图 8所示的实施例二中，基站 802针对不同移动速度的终端，仅生成一个小区重选频率集合。 Specifically, in the first embodiment shown in FIG. 2, the base station 202 generates corresponding multiple cell reselection parameters (such as high speed terminal parameters, medium speed terminal parameters, low speed terminal parameters, etc.) for terminals of different moving speeds; In the second embodiment shown in FIG. 8, the base station 802 generates only one cell reselection frequency set for terminals of different moving speeds.

而对于终端而言，接收到该小区重选频率集合之后，从中选择对应于自身移动速度的小区重选频率，以执行小区重选操作。比如假定图中的终端 804A 为高速终端，则终端 804A在接收到小区重选频率集合时，可以从中选取宏小区频率进行小区重选操作，而对小小区频率则可以不作响应； 4艮定终端 804B 为氏速终端，则终端 804B 在接收到小区重选频率集合时，可以从中选取小小区频率进行小区重选操作，而对宏小区频率则可以不作响应。类似地，对于中速终端也可以仅从中选取某类小区的频率 (图中未示出）。 For the terminal, after receiving the cell reselection frequency set, the cell reselection frequency corresponding to the own moving speed is selected therefrom to perform a cell reselection operation. For example, if the terminal 804A in the figure is a high-speed terminal, the terminal 804A may select a macro cell frequency for cell reselection operation when receiving the cell reselection frequency set, and may not respond to the small cell frequency; When 804B is a fast-speed terminal, terminal 804B may select a small cell frequency for cell reselection operation when receiving the cell reselection frequency set, and may not respond to the macro cell frequency. Similarly, for a medium speed terminal, only the frequency of a certain type of cell (not shown) can be selected therefrom.

通过上述方式，则不同移动速度的终端可以重选到最适合的小区上，比如对于高速终端，可以尽可能地重选至宏小区，避免当重选至小小区时，在空闲状态下进行不必要的频繁重选，同时也避免在进入连接状态后需要进行不必要的切换，导致增加终端不必要的功耗开销。 In the above manner, terminals of different moving speeds can be reselected to the most suitable cell. For example, for a high-speed terminal, the macro cell can be reselected as much as possible, so as to avoid performing the idle state when reselecting to the small cell. Frequent frequent reselection, and also avoid unnecessary switching after entering the connection state, resulting in unnecessary power consumption overhead of the terminal.

具体地，为了让终端从接收到的小区重选频率集合选择适用的小区重选频率，可以为终端预先设置相应的选择规则，以使得终端具有相应的频率选择功能。可以由终端根据不同类型小区对应的频率本身的特征进行区分，比如小小区的频率一般处于较高频段，而宏小区的频率为较低频段。具体来讲，小小区的频率可能为 3.5G左右，而宏小区的频率则通常为 2G 左右。 Specifically, in order for the terminal to select an applicable cell reselection frequency from the received cell reselection frequency set, a corresponding selection rule may be preset for the terminal, so that the terminal has a corresponding frequency selection function. The terminal may be distinguished according to the characteristics of the frequency corresponding to different types of cells. For example, the frequency of the small cell is generally in a higher frequency band, and the frequency of the macro cell is a lower frequency band. Specifically, the frequency of the small cell may be about 3.5G, and the frequency of the macro cell is usually about 2G.

下面将结合图 9至图 13 , 分别从基站 802和终端（包括终端 804A、终端 804B以及其他移动速度的终端）两侧，对图 8所示的实施例进行更为详细的说明。 In the following, with reference to FIG. 9 to FIG. 13, the embodiment shown in FIG. 8 is further modified from the base station 802 and the terminal (including the terminal 804A, the terminal 804B, and other mobile speed terminals). For a detailed explanation.

步骤 902 , 生成小区重选频率集合，并向终端通知所述小区重选频率集合，以由所述终端从中选择对应于自身移动速度的小区重选频率进行小区重选。在该技术方案中，基站仅生成一个小区重选频率集合，其中包含了针对所有移动速度的终端的小区重选频率。同时，由终端根据自身的移动速度，从中选择适用的小区重选频率以执行小区重选操作。由于终端可以根据自身的移动速度对小区重选频率进行选择，使重选到的小区类型与自身的移动速度相匹配，比如使得高速终端尽可能重选至宏小区，从而减少终端的重选次数和避免进入连接状态后执行不必要的切换，降低终端的功耗开销。 Step 902: Generate a cell reselection frequency set, and notify the terminal of the cell reselection frequency set, so that the terminal selects a cell reselection frequency corresponding to the own moving speed to perform cell reselection. In this technical solution, the base station generates only one cell reselection frequency set, which includes the cell reselection frequency of the terminal for all mobile speeds. At the same time, the terminal selects an applicable cell reselection frequency according to its own moving speed to perform a cell reselection operation. The terminal can select the cell reselection frequency according to its own moving speed, so that the reselected cell type matches its own moving speed, for example, the high speed terminal is reselected to the macro cell as much as possible, thereby reducing the number of reselection of the terminal. And avoid unnecessary switching after entering the connection state, reducing the power consumption overhead of the terminal.

优选地，小区重选频率集合中包括任意类型的小区所在的频率。 Preferably, the cell reselection frequency set includes a frequency at which any type of cell is located.

The base station 1000 includes: a data generating module 1002, configured to generate a cell reselection frequency set; and a notification module 1004, configured to notify the terminal of the cell reselection frequency set, to select, by the terminal, a cell weight corresponding to the mobile speed of the terminal Select the frequency for cell reselection. In this technical solution, base station 1000 generates only one cell reselection frequency set containing the cell reselection frequency for the terminals of all mobile speeds. At the same time, the terminal selects an applicable cell reselection frequency according to its own moving speed to perform a cell reselection operation. The terminal can select the cell reselection frequency according to its own moving speed, so that the reselected cell type matches its own moving speed, for example, the high speed terminal is reselected to the macro cell as much as possible, thereby reducing the number of reselection of the terminal. And avoid unnecessary switching after entering the connection state, reducing the power consumption overhead of the terminal.

相对于图 9和图 10所示的基站侧的处理流程和基站构成，对于终端而言，如图 11 所示，其根据获取的小区重选频率集合进行小区重选的流程包括： With respect to the processing flow of the base station side and the base station configuration shown in FIG. 9 and FIG. 10, for the terminal, as shown in FIG. 11, the process of performing cell reselection according to the acquired cell reselection frequency set includes:

步骤 1102 , 获取自身的移动速度。 Step 1102: Obtain a moving speed of itself.

步骤 1 104 , 接收来自基站的小区重选频率集合，并从中选择对应于自身移动速度的小区重选频率，以进行小区重选。在该技术方案中，基站仅生成一个小区重选频率集合，其中包含了针对所有移动速度的终端的小区重选频率。同时，由终端根据自身的移动速度，从中选择适用的小区重选频率以执行小区重选操作。由于终端可以根据自身的移动速度对小区重选频率进行选择，使重选到的小区类型与自身的移动速度相匹配，比如使得高速终端尽可能重选至宏小区，从而减少终端的重选次数和避免进入连接状态后执行不必要的切换，降低终端的功耗开销。 Step 1104: Receive a cell reselection frequency set from the base station, and select a cell reselection frequency corresponding to the mobile speed of the base to perform cell reselection. In this technical solution, the base station generates only one cell reselection frequency set, which includes the cell reselection frequency of the terminal for all mobile speeds. At the same time, the terminal selects an applicable cell reselection frequency according to its own moving speed to perform a cell reselection operation. The terminal can select the cell reselection frequency according to its own moving speed, so that the reselected cell type matches its own moving speed, for example, the high speed terminal is reselected to the macro cell as much as possible, thereby reducing the number of reselection of the terminal. And avoid unnecessary switching after entering the connection state, reducing the power consumption overhead of the terminal.

对应于图 11所示的执行步骤，则相应终端的构成如图 12所示。终端 1200 包括：速度获取模块 1202 , 用于获取所述终端 1200 自身的移动速度；数据接收模块 1204 , 用于接收来自基站的小区重选频率集合；数据选择模块 1206 , 用于从接收到的小区重选频率集合中选择对应于自身移动速度的小区重选频率；重选处理模块 1208 , 用于利用选择的小区重选频率进行小区重选。在该技术方案中，基站仅生成一个小区重选频率集合，其中包含了针对所有移动速度的终端的小区重选频率。同时，由终端 1200 根据自身的移动速度，从中选择适用的小区重选频率以执行小区重选操作。由于终端 1200 可以根据自身的移动速度对小区重选频率进行选择，使重选到的小区类型与自身的移动速度相匹配，比如使得高速终端尽可能重选至宏小区，从而减少终端的重选次数和避免进入连接状态后执行不必要的切换，降低终端 1200的功耗开销。 Corresponding to the execution steps shown in Fig. 11, the configuration of the corresponding terminal is as shown in Fig. 12. The terminal 1200 includes: a speed obtaining module 1202, configured to acquire a moving speed of the terminal 1200 itself; a data receiving module 1204, configured to receive a cell reselection frequency set from the base station; and a data selecting module 1206, configured to receive the received cell The reselection frequency set selects a cell reselection frequency corresponding to its own moving speed; the reselection processing module 1208 is configured to perform cell reselection by using the selected cell reselection frequency. In this technical solution, the base station generates only one cell reselection frequency set, which includes the cell reselection frequency of the terminal for all mobile speeds. At the same time, the terminal 1200 selects an applicable cell reselection frequency according to its own moving speed to perform a cell reselection operation. The terminal 1200 can select the cell reselection frequency according to its own moving speed, so that the reselected cell type matches its own moving speed, for example, the high speed terminal is reselected to the macro cell as much as possible, thereby reducing the terminal reselection. The number of times and avoiding unnecessary switching after entering the connection state reduce the power consumption of the terminal 1200.

以上结合附图详细说明了本发明的技术方案，通过向终端发送小区重选参数，可以让不同速度状态且处于空闲状态的终端驻留在不同的小区层，减少不必要的小区重选开销。同时，如果终端在空闲状态处于合适的小区层，当终端由空闲状态转换为连接状态时，就可以避免为了在连接状态下处于合适的小区层而进行的切换操作。 The technical solution of the present invention is described in detail above with reference to the accompanying drawings. By transmitting a cell reselection parameter to a terminal, terminals in different speed states and in an idle state can be camped on different cell layers, thereby reducing unnecessary cell reselection overhead. At the same time, if the terminal is in the proper cell layer in the idle state, when the terminal is switched from the idle state to the connected state, the handover operation for the appropriate cell layer in the connected state can be avoided.

以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。 The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention.
