Description

网络配置方法、装置和*** 技术领域 Network configuration method, device and system

本发明涉及通信领域，尤其涉及一种网络配置方法、装置和***。背景技术 The present invention relates to the field of communications, and in particular, to a network configuration method, apparatus, and system. Background technique

在 CA (Carrier Aggregation, 载波聚合） ***中，多个载波聚合在一起，可以同时与终端（UE， User Equipment, 用户设备，简称为用户或终端）进行通信，也就是说，终端会有多个服务小区。在这多个服务小区中，一个为主小区（Primary Cell), 其它为辅小区（Secondary Cell)。现有的 CA***中，聚合的小区都在同一个基站下，属于同基站的载波聚合***。 In a carrier aggregation (CA) system, multiple carriers are aggregated and can communicate with a terminal (UE, User Equipment, user equipment, or simply a user or a terminal). That is, multiple terminals exist. Service area. Among the multiple serving cells, one is a primary cell and the other is a secondary cell. In the existing CA system, the aggregated cells are all under the same base station and belong to the carrier aggregation system of the same base station.

在现有的 LTE-A (Long Term Evolution- Advanced,增强型长期演进） CA***中，终端会按照网络的指示，执行相应的切换流程。图 1所示是切换准备阶段流程。首先，网络会给终端进行测量配置，当终端侧的测量结果达到测量事件的要求时，触发测量报告。然后，网络侧参照终端的测量报告、相邻小区的负载等各种元素，判断终端是否需要进行切换，当需要进行切换时，进入切换准备阶段。这时，源基站会向目标基站发送切换请求（Handover Request) 消息。在切换请求消息中，会包括一个候选小区信息列表： candidateCellInfoList-rlO。在这个列表中，针对每个有测量结果的频率，会将测量结果最好的那个小区包含在内，包括这个小区的 PCI (Physical Cell ID, 物理小区标识）和下行频率，并且还可能包括这个小区的测量结果。源基站将这个列表提供给目标基站，以便于目标基站选择终端切换之后的辅小区。在目标基站选择了终端切换之后的辅小区之后，发送切换请求响应（Handover Request Ack) 消息给源基站，在切换请求响应消息中，配置有终端在切换之后的辅小区等信息。源基站接收到切换请求响应消息之后，将这个消息再发送给终端（切换请求响应消息从源基站发送给终端时，叫做连接重配消息（RRCConnectionReconfiguration))，终端就可以获知其在切换之后的辅小区配置。然后，终端和网络侧就可以进行切换的后续流程。切换的后续流程本文不再详述。 In the existing LTE-A (Long Term Evolution-Advanced) CA system, the terminal performs the corresponding handover procedure according to the indication of the network. Figure 1 shows the process of the switch preparation phase. First, the network will perform measurement configuration for the terminal. When the measurement result on the terminal side meets the requirements of the measurement event, the measurement report is triggered. Then, the network side refers to the measurement report of the terminal, the load of the neighboring cell, and the like, and determines whether the terminal needs to perform handover. When the handover is required, the handover preparation phase is entered. At this time, the source base station sends a Handover Request message to the target base station. In the handover request message, a candidate cell information list is included: candidateCellInfoList-rlO. In this list, for each frequency with a measurement result, the cell with the best measurement result is included, including the PCI (Physical Cell ID) and downlink frequency of the cell, and may also include this The measurement result of the cell. The source base station provides this list to the target base station, so that the target base station selects the secondary cell after the terminal handover. After the target base station selects the secondary cell after the terminal handover, a handover request response (Handover Request Ack) message is sent to the source base station, and in the handover request response message, information such as the secondary cell after the handover of the terminal is configured. After receiving the handover request response message, the source base station retransmits the message to the terminal. When the handover request response message is sent from the source base station to the terminal, it is called a connection reconfiguration message (RRCConnectionReconfiguration), and the terminal can learn its auxiliary after the handover. Cell configuration. Then, the terminal and the network side can perform the subsequent process of the handover. The subsequent process of switching is not detailed here.

在目前的 LTE-A***中，主要部署了宏小区。未来随着业务量的增加，可能要继续部署小小区。小小区的覆盖面积比较小，但是数量比较多。所以，如果只是简单进行小小区的部署，不进行控制和结构优化，就会造成移动的健壮性降低，控制信令负担增加等很多方面的问题。为了解决这些问题，同时为了提高单个用户流量，业界就提出了一种新型网络协议结构：双连接。在双连接结构下，终端可以与不同基站下的小区进行通信，可以与网络同时建立两个或多个连接：一个主连接（MConnectivity) 和一个或多个辅连接（SConnectivity)。主连接在终端与主基站（MeNB: Master eNB) 之间，辅连接在终端与辅基站（SeNB: Secondary eNB) 之间。一般来讲，相对于辅连接，主连接会承载更多的功能，比如，主连接可以承载寻呼业务和广播业务，但是辅连接可能不会承载这些业务。再比如，主连接可以承载信令和数据，而辅连接可能只承载数据或信令业务。 In the current LTE-A system, a macro cell is mainly deployed. In the future, as the volume of business increases, it may be necessary to continue to deploy small cells. The coverage area of small cells is relatively small, but the number is relatively large. So if it's just simple The deployment of small cells without control and structural optimization will result in many problems such as reduced mobility and increased control signaling burden. In order to solve these problems, and in order to increase the traffic of individual users, the industry has proposed a new network protocol structure: dual connectivity. In the dual connectivity structure, the terminal can communicate with cells under different base stations, and two or more connections can be established simultaneously with the network: one primary connection (MConnectivity) and one or more secondary connections (SConnectivity). The primary connection is between the terminal and the primary base station (MeNB: Master eNB), and the secondary connection is between the terminal and the secondary base station (SeNB: Secondary eNB). In general, the primary connection carries more functions than the secondary connection. For example, the primary connection can carry paging services and broadcast services, but the secondary connections may not carry these services. As another example, the primary connection can carry signaling and data, while the secondary connection may only carry data or signaling traffic.

在双连接结构中也存在主小区和辅小区，并且这些小区可以与一个终端进行通信。但是，这些小区可以属于不同的基站，比如，分别属于宏小区基站和小小区基站，或者属于不同的小小区基站。与现有的 CA***相比，双连接结构实际上属于异基站的载波聚合***。 There are also primary and secondary cells in the dual connectivity structure, and these cells can communicate with one terminal. However, these cells may belong to different base stations, for example, belong to a macro cell base station and a small cell base station, respectively, or belong to different small cell base stations. Compared with the existing CA system, the dual connectivity structure actually belongs to the carrier aggregation system of the different base station.

双连接结构有很多应用场景，图 2、 3分别为场景 1和场景 2。在场景 1中，宏小区和小小区在同一个频率上，通过非理想的中继连接。在这种场景下，双连接结构主要用来增强移动的健壮性和减少切换信令开销。在场景 1中，一般情况下， ***会选择宏基站下的小区为主小区。在场景 2中，宏小区和小小区在不同频率上，通过非理想的中继连接。在场景 2中，双连接结构可以用来提高单用户流以增强移动的健壮性和减少切换信令开销。在场景 2中，一般情况下， ***会选择宏基站下的小区为主小区。 There are many application scenarios for the dual connectivity structure. Figures 2 and 3 are scenario 1 and scenario 2, respectively. In scenario 1, the macro cell and the small cell are connected on the same frequency through a non-ideal relay. In this scenario, the dual connectivity structure is mainly used to enhance the robustness of the mobile and reduce the handover signaling overhead. In scenario 1, in general, the system selects the cell under the macro base station as the primary cell. In scenario 2, the macro cell and the small cell are connected at different frequencies through a non-ideal relay. In scenario 2, a dual connectivity structure can be used to enhance single-user flows to enhance mobility robustness and reduce handover signaling overhead. In scenario 2, in general, the system selects the cell under the macro base station as the primary cell.

发明人在实现本发明的过程中发现，在双连接结构下，终端也需要进行相关测量并在满足触发条件时触发测量报告。同时，在切换准备阶段，在切换请求消息中，源基站可以报告给目标基站一个候选小区信息列表，以便于目标基站选择辅小区。但是，如果切换发生在场景 1下，或者发生切换的网络中存在某个频率，在这个频率上既有宏小区在工作，又有小小区在工作，那么，就会出现如下问题。 In the process of implementing the present invention, the inventors found that under the dual connectivity structure, the terminal also needs to perform related measurements and trigger a measurement report when the trigger condition is met. Meanwhile, in the handover preparation phase, in the handover request message, the source base station may report to the target base station a candidate cell information list, so that the target base station selects the secondary cell. However, if the handover occurs in scenario 1, or there is a certain frequency in the network where the handover occurs, at this frequency, both the macro cell is working and the small cell is working, then the following problem occurs.

如图 4所示，终端在切换之前存在双连接，分别与宏基站下的小区 Ml和小小区基站下的小区 S1进行通信。如果在切换请求消息中的候选小区信息列表中仍然只报告一个最好的小区，那么在 fl上报告的最好小区可能是 M2。但是，在这种场景下，为了更好的利用双连接结构， M2更可能的是被网络侧配成主小区而非辅小区。那么，如果目标基站只得到 fl频率上 M2的信息，尽管 S4可能是最好的辅小区选择，网络仍可能作出下述错误配置： As shown in FIG. 4, the terminal has a dual connection before the handover, and communicates with the cell M1 under the macro base station and the cell S1 under the small cell base station, respectively. If only one of the best cells is still reported in the candidate cell information list in the handover request message, then the best cell reported on fl may be M2. However, in this scenario, in order to make better use of the dual connectivity structure, M2 is more likely to be configured as a primary cell rather than a secondary cell by the network side. Then, If the target base station only obtains M2 information on the fl frequency, although S4 may be the best secondary cell selection, the network may still make the following misconfiguration:

( 1 ) 选择错误的辅小区，比如 S5 ; (1) Select the wrong secondary cell, such as S5;

(2) 不配置双连接结构，只配置了宏基站下的小区作为服务小区； (2) The dual-connection structure is not configured, and only the cell under the macro base station is configured as the serving cell;

(3 ) 配置 S4作为主小区。 (3) Configure S4 as the primary cell.

在情况（1 ) 和（2) 下，终端在切换之后很快移动到 S2的覆盖范围之内，由于配置了错误辅小区或没有配置双连接结构，终端在 S2的覆盖范围之内就可能经受强干扰而掉话，移动鲁棒性明显降低，严重影响用户体验。如果在情况（3 ) 下，终端掉话的可能性与情况（1 )、（2) 比较下要低一些，但是，用户在移动出 S4覆盖范围之后还要作一次切换，比如，切换到 M2 下，这样就增加了切换的信令开销。 In cases (1) and (2), the terminal moves to the coverage of S2 very quickly after the handover. Due to the configuration of the error secondary cell or the configuration of the dual connection structure, the terminal may be subject to the coverage of S2. Strong interference and dropped calls, mobile robustness is significantly reduced, seriously affecting the user experience. If in case (3), the possibility of the terminal dropping is lower than the situation (1) and (2), but the user has to make a switch after moving out of the S4 coverage, for example, switching to M2. Next, this increases the signaling overhead of the handover.

However, it can be understood that the embodiment of the present invention is not limited to the foregoing scenario, and is applicable to other scenarios involving cell handover.

实施例 1 Example 1

本发明实施例提供了一种网络配置方法。图 5是该方法的流程图，请参照图 5，该方法包括： The embodiment of the invention provides a network configuration method. Figure 5 is a flow chart of the method. Referring to Figure 5, the method includes:

步骤 501 : 基站根据终端测量报告，从多个在既部署在宏小区基站又部署在小小区基站的频率上的小区中，选择预定数量的测量结果最好的小区，生成候选小区信息列表； Step 501: The base station selects a predetermined number of cells with the best measurement result from the plurality of cells deployed on the frequency of the macro cell base station and the small cell base station according to the terminal measurement report, and generates a candidate cell information list.

步骤 502: 所述基站将所述候选小区信息列表发送给目标基站，以便所述目标基站参考所述候选小区信息列表为所述终端选择切换后的辅小区。 Step 502: The base station sends the candidate cell information list to the target base station, so that the target base station selects the switched secondary cell for the terminal by referring to the candidate cell information list.

通过本实施例的方法，基站根据终端上报的测量结果（简称为终端测量报告），对于该测量结果中，从多个在既部署在宏小区基站中又部署在小小区基站中的频率上的小区中，选择预定数量的测量结果最好的小区，添加到候选小区信息列表中，从而生成候选小区信息列表，提供给目标基站。由此，相对于不考虑该频率是否是既部署在宏小区基站中又部署在小小区基站，而只上报一个测量结果最好的小区的情况，提高了小小区基站下的小区被包括进候选小区信息列表中的概率，增加了目标基站为终端配置最优双连接的概率。 According to the method of the embodiment, the base station, according to the measurement result reported by the terminal (referred to as the terminal measurement report for short), is used in the measurement result from a plurality of frequencies that are deployed in both the macro cell base station and the small cell base station. In the cell, a predetermined number of cells with the best measurement result are selected and added to the candidate cell information list, thereby generating a candidate cell information list and providing the target cell information list to the target base station. Therefore, the cell under the small cell base station is included in the candidate, regardless of whether the frequency is deployed in both the macro cell base station and the small cell base station, and only one cell with the best measurement result is reported. The probability in the cell information list increases the probability that the target base station configures the optimal dual connectivity for the terminal.

在本实施例中，基站可以首先获取其所在网络的频率部署信息，以确定在其所在的网络中，有哪些频率既部署在宏小区基站中也部署在小小区基站中，从而可以从终端测量报告中，从其多个部署在这些频率上的小区中选择预定数量的测量结果最好的小区，添加入候选小区信息列表。其中，该频率部署信息可以通过网管***配置，也可以通过基站之间的消息交互得到，例如相邻基站间可以交互自己所配置的频率，各基站由此可以确定其所在的网络的频率部署信息。以上只是举例说明，本实施例并不以此作为限制。 In this embodiment, the base station may first obtain the frequency deployment information of the network in which it is located to determine which frequencies are deployed in both the macro cell base station and the small cell base station in the network where the network is located, so that the base station can measure from the terminal. In the report, a predetermined number of cells with the best measurement results are selected from a plurality of cells deployed on the frequencies, and added to the candidate cell information list. The frequency deployment information may be configured by the network management system or by message interaction between the base stations. For example, the neighboring base stations may exchange their own configured frequencies, and each base station may determine the frequency deployment information of the network where the base station is located. . The above is only an example, and the embodiment is not limited thereto.

其中，如果有多个频率既部署在宏小区基站中也部署在小小区基站中，可以从其多个部署在这些频率上的小区中，选择上述预定数量的测量结果最好的小区，添加入候选小区信息列表。例如，频率 fl和 β都是既部署在宏小区基站中也部署在小小区基站中，针对测量报告中多个部署在 fl上的小区中，选择预定数量的测量结果最好的小区添加入候选小区信息列表，针对测量报告中多个部署在 β上的小区中，也选择预定数量的测量结果最好的小区添加入候选小区信息列表，从而生成包含上述针对 fl选择出的候选小区以及针对 β选择出的候选小区的候选小区信息列表。 If a plurality of frequencies are deployed in the macro cell base station and are also deployed in the small cell base station, the predetermined number of cells with the best measurement results may be selected from the plurality of cells deployed on the frequencies. Candidate cell information list. For example, the frequencies fl and β are both deployed in the macro cell base station and also in the small cell base station. For a plurality of cells deployed on the fl in the measurement report, the cell with the best number of measurement results is selected to be added to the candidate. For the cell information list, for a plurality of cells deployed in the measurement report, a cell with a predetermined number of measurement results is also added to the candidate cell information list, thereby generating a candidate cell including the foregoing selected for fl and for β. A candidate cell information list of candidate cells is selected.

在步骤 501的一个实施方式中，基站可以根据终端测量报告，从多个在既部署在宏小区基站又部署在小小区基站的频率上的小区中，选择两个测量结果最好的小区，生成候选小区信息列表。 In an implementation of step 501, the base station may select two cells with the best measurement result from the plurality of cells deployed on the frequency of the macro cell base station and the small cell base station according to the terminal measurement report. Candidate cell information list.

以图 4为例，频率 fl既部署在宏小区基站又部署在小小区基站，终端根据测量结果，上报了 Ml、 M2、 SI和 S4这四个小区的测量结果，其中， Ml、 M2为宏小区， S1和 S4为小小区，则针对该测量结果中的这四个部署在 fl上的小区，根据本实施方式的方法，基站从上述四个小区中选择两个测量结果最好的小区添加入候选小区信息列表。由此，提高了在小小区基站下的小区被包括进候选小区信息列表中的概率，并提高了目标基站为终端配置最优双连接的概率。 As shown in Figure 4, the frequency fl is deployed in both the macro cell base station and the small cell base station. The terminal reports the measurement results of the four cells M1, M2, SI, and S4 according to the measurement result, where Ml and M2 are macros. The cell, S1 and S4 are small cells, and for the four cells deployed on the fl in the measurement result, according to the method of the embodiment, the base station selects two cells with the best measurement result from the four cells. Enter the candidate cell information list. Thereby, the probability that the cell under the small cell base station is included in the candidate cell information list is improved, and the probability that the target base station configures the optimal dual connection for the terminal is improved.

在步骤 501的另一个实施方式中，基站可以获取终端测量报告中各个小区的种类 In another implementation of step 501, the base station may acquire the type of each cell in the terminal measurement report.

(比如，是宏小区还是小小区），然后从宏小区中选择一个测量结果最好的小区，从小小区中选择一个测量结果最好的小区，据此生成候选小区信息列表。 (For example, whether it is a macro cell or a small cell), then select a cell with the best measurement result from the macro cell, select a cell with the best measurement result from the small cell, and generate a candidate cell information list accordingly.

仍以图 4为例，根据本实施方式的方法，由于 Ml、 M2为宏小区， S1和 S4为小小区，基站可以从 Ml和 M2中选择一个测量结果最好的小区以及从 S1和 S4中选择一个测量结果更好的小区，添加入候选小区信息列表。由此，目标基站可以得到一个频率上最好的宏小区和小小区的信息，保证了目标基站在配置双连接结构时配置最好的小区。 Still taking FIG. 4 as an example, according to the method of the present embodiment, since M1 and M2 are macro cells, and S1 and S4 are small cells, the base station can select one cell with the best measurement result from M1 and M2 and from S1 and S4. Select a cell with better measurement result and add it to the candidate cell information list. Therefore, the target base station can obtain information of the best macro cell and small cell in the frequency, and ensures that the target base station configures the best cell when configuring the dual connectivity structure.

其中，终端测量报告中各小区的种类可以通过网管***配置获得，也可以通过基站之间的消息交互得到，本实施例并不以此作为限制。例如，如果基站通过相互之间的信息交互得到相邻基站下都有哪些小区（也即相邻基站小区的 PCI)，同时，也可以得到相邻基站的种类（也即是宏小区基站还是小小区基站），如果相邻基站同一频率上小区 PCI唯一，那么，基站就可以根据终端测量报告中的 PCI来得到被测量小区的种类。以上只是举例说明，本实施例并不以此作为限制。 The type of the cell in the terminal measurement report can be obtained through the configuration of the network management system, or can be obtained through message interaction between the base stations. This embodiment is not limited thereto. For example, if the base stations pass each other The information exchange obtains which cells are in the neighboring base station (that is, the PCI of the neighboring base station cell), and at the same time, the type of the neighboring base station (that is, the macro cell base station or the small cell base station) can also be obtained, if the adjacent base station The cell PCI is unique on the same frequency, and then the base station can obtain the type of the measured cell according to the PCI in the terminal measurement report. The above is only an example, and the embodiment is not limited thereto.

(是宏小区还是小小区），然后仅从小小区中选择一个测量结果最好的小区，据此生成候选小区信息列表。 (is it a macro cell or a small cell), and then selects only one cell with the best measurement result from the small cell, and generates a candidate cell information list accordingly.
