Description

一种随机接入的方法、基站以及用户设备Random access method, base station and user equipment

技术领域Technical field

本申请涉及但不限于通信技术，尤指一种随机接入的方法、基站以及用户设备。The present application relates to, but is not limited to, communication technologies, and in particular, to a random access method, a base station, and a user equipment.

背景技术Background technique

集群通信***是为了满足行业用户指挥调度等需求而开发，其是面向特定行业应用的专用无线通信***。集群通信***区别于公众无线电移动通信***的主要特点为：除了可以提供移动电话的双向通话功能外，还可提供***内的群(组)呼、全呼，甚至建立通话优先级别，并可以进行优先等级呼叫、紧急呼叫等一般移动电话所不具备的通信；还可提供动态重组、***内虚拟专网等特殊功能。这些特点特别适合警察、国家***门专用通信以及机场、海关、公交运输、抢险救灾等指挥调度需要，所以，集群通信***在政府部门、公共安全、应急通信、电力、民航、石油化工、军队及企业等领域有着广泛的应用，是一种多用途、高效能的无线通信***，并在世界各地形成了独立于公众移动通信网之外的专用通信网。The trunking communication system is developed to meet the needs of industry users for command and dispatch, etc. It is a dedicated wireless communication system for specific industry applications. The main features of the trunking communication system different from the public radio mobile communication system are: in addition to providing the two-way calling function of the mobile phone, it can also provide group (group) calls, full calls, and even establish call priority levels in the system, and can perform Priority call, emergency call, etc., which are not available in general mobile phones; special functions such as dynamic reorganization and virtual private network in the system are also provided. These features are especially suitable for police, national security department-specific communications, and command and dispatch needs for airports, customs, public transportation, disaster relief, etc. Therefore, the trunking communication system is in government departments, public safety, emergency telecommunications, electric power, civil aviation, petrochemical, military and It has a wide range of applications in enterprises and other fields. It is a versatile and high-performance wireless communication system, and has formed a dedicated communication network independent of the public mobile communication network around the world.

然而，随着频谱资源日益紧缺，对公网集群的呼声越发高涨。公网集群是指在现有的公共移动通信网基础上展开特定的集群通信业务。为确保集群型用户设备在进行关键业务情况下能持续通话的能力，目前，标准化机构第三代伙伴组织计划(Third Generation Partnership Projects，3GPP)提出了对服务于公共安全的孤立的无线接入网模式(Isolated E-UTRAN Operation，IOPS)的需求，所谓IOPS网络模式是指当基站在回路中断或者回路出现故障而不能正常传输信令、数据的情况下，仍能为集群型用户设备提供一定级别的通信能力。IOPS网络模式要求该网络模式启动后，只对集群型用户设备提供服务，不允许普通型用户设备接入该网络模式。However, as spectrum resources become increasingly scarce, calls for public network clusters are growing. Public network cluster refers to the development of specific trunking communication services based on the existing public mobile communication network. In order to ensure the ability of clustered user equipment to continue to communicate under critical business conditions, the Third Generation Partnership Projects (3GPP) has proposed an isolated wireless access network for public safety. The requirement of the mode (Isolated E-UTRAN Operation, IOPS), the so-called IOPS network mode means that when the base station fails to transmit signaling and data normally in the event of a loop interruption or a loop failure, it can still provide a certain level for the cluster type user equipment. Communication capabilities. After the network mode is enabled, the IOPS network mode only provides services to the cluster-type user equipment, and does not allow ordinary user equipments to access the network mode.

目前，现有的技术方案中存在以下问题：当集群网络启动后，基站侧并不能确定请求接入的用户设备属于普通型用户设备还是集群型用户设备，从而无法做到仅对集群型用户设备的接入请求进行响应。 At present, the existing technical solutions have the following problems: after the cluster network is started, the base station side cannot determine whether the user equipment requested to be accessed belongs to a common type user equipment or a cluster type user equipment, and thus cannot be used only for the cluster type user equipment. The access request responds.

下文中将结合附图对本发明的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机***中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。 The steps illustrated in the flowchart of the figures may be executed in a computer system such as a set of computer executable instructions. Also, although logical sequences are shown in the flowcharts, in some cases the steps shown or described may be performed in a different order than the ones described herein.

在介绍本发明实施例提供的技术方案之前，先对相关的现有技术进行简要说明：Before introducing the technical solutions provided by the embodiments of the present invention, the related prior art is briefly described:

现有的长期演进***(Long Term Evolution，LTE)将一个小区的64条前导(Preamble)分成两类：基于竞争的随机接入前导和基于非竞争的随机接入前导。基于竞争的随机接入前导又可以被分为两组：组(Group)A和Group B，如图1所示，值得一提的是，Group A或Group B中包括的随机接入前导的个数为自然数，示例性的，根据现有LTE协议规定，Group A包括的随机接入前导的个数最小为4，Group B包括的随机接入前导的个数可以为0。用户设备(User Equipment，UE)根据自身需要来选择对应的Group。基站广播的***信息中包含有指示Group A和Group B的名称(其中，用1比特(bit)信息的一个值来指示)以及两个集合中各自包含的随机接入前导(例如，可以用6bit信息对应的值来表示随机接入前导的索引号，6bit信息可以指示64个前导)的信息。另外，目前LTE***的标准化协议中也支持对基于竞争的随机接入前导不进行分组的情况。The existing Long Term Evolution (LTE) classifies 64 preambles of a cell into two categories: a contention based random access preamble and a non-contention based random access preamble. The contention-based random access preamble can be further divided into two groups: Group A and Group B, as shown in Figure 1. It is worth mentioning that the random access preambles included in Group A or Group B are The number is a natural number. Illustratively, according to the existing LTE protocol, the number of random access preambles included in Group A is at least 4, and the number of random access preambles included in Group B may be 0. The user equipment (User Equipment, UE) selects the corresponding group according to its own needs. The system information broadcasted by the base station includes a name indicating Group A and Group B (indicated by a value of 1 bit of information) and a random access preamble included in each of the two sets (for example, 6 bits can be used) The value corresponding to the information indicates the index number of the random access preamble, and the 6-bit information indicates the information of 64 preambles. In addition, the current standardization protocol of the LTE system also supports the case where the contention-based random access preamble is not grouped.

在本发明实施例中，在对基于竞争的随机接入前导进行分组时，增加一个集合Group C且Group C为第一用户设备(如集群型用户设备等特定用户设备)专用，如图2所示。当网络启动后，基站将新扩展的Group C的相关参数发送给小区内的用户设备(包括第一用户设备和第二用户设备(如普通用户设备))，其中，第一用户设备使用Group C中的随机接入前导发送接入请求，基站响应第一用户设备的接入请求，对于第二用户设备，是无法使用Group C中的随机接入前导的，基站侧将会用Group C中的随机接入前导作为参考的随机接入前导对用户设备发送的随机接入前导进行检测，因此只会检测出第一用户设备发送的选自于Group C中的随机接入前导，只会对第一用户设备做出随机接入响应。In the embodiment of the present invention, when grouping the contention-based random access preamble, adding a set Group C and group C is dedicated to the first user equipment (such as a specific user equipment such as a cluster type user equipment), as shown in FIG. 2 Show. After the network is started, the base station sends the related parameters of the newly extended Group C to the user equipment (including the first user equipment and the second user equipment (such as a common user equipment)) in the cell, where the first user equipment uses the Group C. The random access preamble sends an access request, and the base station responds to the access request of the first user equipment. For the second user equipment, the random access preamble in the group C cannot be used, and the base station side uses the group C. The random access preamble with the random access preamble as a reference detects the random access preamble sent by the user equipment, and therefore only detects the random access preamble selected by the first user equipment and is selected from the group C, and only A user equipment makes a random access response.

于本实施例中，第一用户设备包括集群型用户设备，集群型用户设备是指支持当前集群网络并被当前集群网络期望接入的用户设备；第二用户设备包括不支持当前集群网络和/或当前集群网络不期望接入的用户设备。前述的用户设备具体可以是各种无线通信终端，本发明实施例提供的技术方案并不仅限于应用于IOPS网络模式，还可以适用于各种需要只对一部分特殊用户设备提供服务的通信场景。In this embodiment, the first user equipment includes a cluster type user equipment, and the cluster type user equipment refers to a user equipment that supports the current cluster network and is expected to be accessed by the current cluster network; the second user equipment includes the current cluster network and/or not supported. Or user equipment that the current cluster network does not expect to access. The foregoing user equipment may be specifically a variety of wireless communication terminals. The technical solution provided by the embodiments of the present invention is not limited to the application to the IOPS network mode, and may be applicable to various needs only for a part of special users. A communication scenario for providing services.

下面的实施例中以第一用户设备为集群型用户设备，第二用户设备为普通型用户设备为例进行说明。In the following embodiments, the first user equipment is a cluster type user equipment, and the second user equipment is a general type user equipment.

本发明实施例提供一种随机接入的方法，基于基站侧，如图3所示，该方法包括以下步骤：An embodiment of the present invention provides a method for random access. Based on the base station side, as shown in FIG. 3, the method includes the following steps:

In the embodiment of the present invention, the contention-based random access preamble is divided into two large sets: a first random access preamble set and a second random access preamble set, where the first random access preamble set The random access preamble is used for the random access of the cluster type user equipment, and the random access preamble in the second random access preamble set is used for random access of the common type user equipment; in the embodiment of the present invention, based on the competition A possible grouping method of the random access preamble may be to divide the contention-based random access preamble into Group A, Group B, and Group C. In the new grouping mode, the random connection in Group A and Group B The incoming preamble is still provided to the normal type user equipment for random access, and the random access preamble in the Group C is provided to the cluster type user equipment for random access; it can be understood that in the foregoing new Group mode, as described in the first random access preamble set of Group C, embodiments of the present invention the second random access preamble set of Group A and Group B and current embodiment of the present invention.

实施例一Embodiment 1

在本实施例中，集群网络以IOPS网络为例，集群型用户设备以IOPS UE(即支持IOPS网络的UE)为例，本实施例的应用场景为：用户设备初始接入发起的随机接入。如图5所示，本实施例包括以下步骤：In this embodiment, the cluster network is an IOPS network, and the cluster type user equipment is an IOPS UE (ie, a UE supporting the IOPS network). The application scenario in this embodiment is: random access initiated by the user equipment. . As shown in FIG. 5, the embodiment includes the following steps:

步骤一、IOPS网络启动，基站通过广播SIB2发送随机接入信道的配置信息，其中，配置信息中包括：组(Group)A、组(Group)B以及组(Group)C的信息。Step 1: The IOPS network is started, and the base station sends the configuration information of the random access channel by broadcasting the SIB2, where the configuration information includes: information of the group A, the group B, and the group C.

其中，对于与IOPS网络对应的Group C的门限信息，如果UE属于IOPSUE支持该IOPS网络，则该IOPS UE的预设标识信息(该UE的指示支持某个IOPS网络的值)与Group C的门限信息匹配，比如该IOPS网络为公安***或和其他某几个***专用，该IOPS网络就设置对应于前述几个***标识的门限信息，支持前述几个***的IOPS UE中设置有与前述门限信息匹配的预设标识信息，当两者匹配时该UE选择Group C。The threshold information of the Group C corresponding to the IOPS network, if the UE belongs to the IOPS UE and supports the IOPS network, the preset identifier information of the IOPS UE (the indication of the UE supports the value of an IOPS network) and the threshold of the Group C Information matching, for example, the IOPS network is dedicated to the public security system or to some other systems, and the IOPS network sets threshold information corresponding to the foregoing system identifiers, and supports the threshold information of the IOPS UEs of the foregoing systems. Matching preset identification information, the UE selects Group C when the two match.

步骤二、UE收到随机接入信道(Random Access Channel，RACH)的配置信息后进行判决，如果UE的预设标识信息与该IOPS网络对应的Group C的门限信息匹配，则确定需要使用Group C。Step 2: After receiving the configuration information of the random access channel (RACH), the UE performs the decision. If the preset identifier information of the UE matches the threshold information of the Group C corresponding to the IOPS network, it is determined that the group C needs to be used. .

关于Group C的参数设置可参考现有的LTE***中对Group A、Group B的设置，Group C的参数的发送优先级高于Group A、Group B的参数：For the setting of the parameters of Group C, refer to the settings of Group A and Group B in the existing LTE system. The sending priority of Group C parameters is higher than the parameters of Group A and Group B:

示例性的，现有的随机信道配置信息(RACH-ConfigCommon information element)包括：Exemplarily, the existing random channel configuration information (RACH-ConfigCommon information element) includes:

其中，numberOfRA-Preambles为基于竞争的随机接入前导的个数，sizeOfRA-PreamblesGroupA为Group A中随机接入前导的个数，其中，对于numberOfRA-Preambles，以n4为例，表示小区可分配的随机接入前导为4个，其余几个参数的含义参照理解；对于sizeOfRA-PreamblesGroupA，以n4为例，表示Group A中随机接入前导的个数为4个，其余几个参数的含义参照理解。The numberOfRA-Preambles is the number of contention-based random access preambles, and the sizeOfRA-PreamblesGroupA is the number of random access preambles in the group A. For the numberOfRA-Preambles, n4 is used as an example to indicate that the cells can be allocated randomly. The number of access preambles is four, and the meanings of the other parameters are understood. For sizeOfRA-PreamblesGroupA, n4 is used as an example to indicate that the number of random access preambles in Group A is four. The meanings of the other parameters are understood.

Group B中的随机接入前导由numberofRA-Preambles和sizeOfRA-preamblesGroupA计算得到：The random access preamble in Group B is calculated by numberofRA-Preambles and sizeOfRA-preamblesGroupA:

如果(numberofRA-Preambles)＝(sizeOfRA-PreamblesGroupA)，则Group B中的随机接入前导的个数为0，也即不存在，Group A中的随机接入前导的索引号从0～(sizeOfRA-preamblesGroupA－1)；If (numberofRA-Preambles)=(sizeOfRA-PreamblesGroupA), the number of random access preambles in Group B is 0, that is, there is no existence. The index number of the random access preamble in Group A is from 0 to (sizeOfRA- preamblesGroupA-1);

如果(numberofRA-Preambles)>(sizeOfRA-PreamblesGroupA)，则Group B存在，且Group A中的随机接入前导的索引号从If (numberofRA-Preambles)>(sizeOfRA-PreamblesGroupA), Group B exists, and the index number of the random access preamble in Group A is from

0～(sizeOfRA-PreamblesGroupA－1)，Group B中的随机接入前导的索引号从(sizeOfRA-PreamblesGroupA)～(numberofRA-Preambles－1)。0 to (sizeOfRA-PreamblesGroupA-1), the index number of the random access preamble in Group B is from (sizeOfRA-PreamblesGroupA) to (numberofRA-Preambles-1).

本发明实施例中，对于Group C中包含的随机接入前导的个数的描述，可以是在现有协议的基础上增加两个扩展参数：In the embodiment of the present invention, for the description of the number of random access preambles included in the Group C, two extended parameters may be added on the basis of the existing protocol:

参数1：sizeOfRA-PreamblesGroupC；Parameter 1: sizeOfRA-PreamblesGroupC;

参数2：sizeOfRA-PreamblesGroupCParameter 2: sizeOfRA-PreamblesGroupC

这样，Group B中的随机接入前导由(numberofRA-Preambles)和(sizeOfRA-PreamblesGroupA)以及(sizeOfRA-PreamblesGroupC)得到：Thus, the random access preamble in Group B is obtained by (numberofRA-Preambles) and (sizeOfRA-PreamblesGroupA) and (sizeOfRA-PreamblesGroupC):

如果(numberofRA-Preambles)＝(sizeOfRA-PreamblesGroupA)+(sizeOfRA-PreamblesGroupC)，则Group B中的随机接入前导的个数为0，也即不存在，Group A中的随机接入前导的索引号从If (numberofRA-Preambles)=(sizeOfRA-PreamblesGroupA)+(sizeOfRA-PreamblesGroupC), the number of random access preambles in Group B is 0, that is, there is no existence, and the index number of the random access preamble in Group A From

0～(sizeOfRA-PreamblesGroupA－1)；0~(sizeOfRA-PreamblesGroupA-1);

Group C中的随机接入前导的索引号从The index number of the random access preamble in Group C is from

(sizeOfRA-PreamblesGroupA)～(sizeOfRA-PreamblesGroupC－1)；(sizeOfRA-PreamblesGroupA)~(sizeOfRA-PreamblesGroupC-1);

如果(numberofRA-Preambles)>(sizeOfRA-preamblesGroupA)+(sizeOfRA-PreamblesGroupC)，则Group B存在，且Group A中的随机接入前导的索引号从If (numberofRA-Preambles)>(sizeOfRA-preamblesGroupA)+(sizeOfRA-PreamblesGroupC), then Group B exists, and the index number of the random access preamble in Group A is from

0～(sizeOfRA-PreamblesGroupA－1)，0~(sizeOfRA-PreamblesGroupA-1),

Group B中的随机接入前导的索引号从The index number of the random access preamble in Group B is from

(sizeOfRA-PreamblesGroupA)～((numberofRA-Preambles)－(sizeOfRA-PreamblesGroupC)－1)。(sizeOfRA-PreamblesGroupA)~((numberofRA-Preambles)-(sizeOfRA-PreamblesGroupC)-1).

(numberofRA-Preambles－sizeOfRA-PreamblesGroupC)～(numberofRA-Preambles－1)；(numberofRA-Preambles-sizeOfRA-PreamblesGroupC)~(numberofRA-Preambles-1);

在IOPS网络中，如果不需要普通UE接入，为尽量避免前导碰撞，GroupA中随机接入前导的个数的值设置地尽量小(例如可以选取为最小的4)，Group C中随机接入前导的个数的值尽量大(例如可以选取为上述新增参数2中最大的60)；In an IOPS network, if normal UE access is not required, in order to avoid preamble collision as much as possible, the value of the number of random access preambles in GroupA is set as small as possible (for example, can be selected as the smallest 4), and random access in Group C The value of the number of preambles is as large as possible (for example, it can be selected as the largest 60 of the above new parameters 2);
