The method of this embodiment is particularly applicable to a base station direct architecture in which data transmission can be directly performed between base stations. For example, as shown in FIGS. 2A-2D , all of them are clustered network architectures in different forms, and a base station can directly perform data transmission with one or more other base stations. As shown in Figures 2A and 2B, the access network includes a management control center, cluster head base stations and sub base stations.

本发明各实施例的I-X2接口是一个开放性的接口，其主要功能是实现基站之间的信令与业务数据的交换。从逻辑角度来看，I-X2接口是基站之间的点到点接口。在本实施例中，该I-X2接口主要负责实现各个基站直通时的信令交互，完成各个基站的用户面传数据（即业务数据）的承载传输。图3A从I-X2接口的控制面协议栈角度示出了源基站和目标基站之间的信令交互的过程；图3B从I-X2接口的用户面协议栈角度示出了源基站和目标基站之间的业务数据交换的过程。如图3A所示，I-X2接口的控制面协议栈主要包括：物理层、数据链路层、IP层、流控制传输协议层和应用层。如图3B所示，I-X2接口的用户面协议栈主要包括：物理层、数据链路层、IP层、用户数据报协议（User Datagram Protocol；简称为：UDP）层、通用数据传输层和业务数据层。The I-X2 interface of each embodiment of the present invention is an open interface, and its main function is to realize the exchange of signaling and service data between base stations. From a logical point of view, the I-X2 interface is a point-to-point interface between base stations. In this embodiment, the I-X2 interface is mainly responsible for realizing the signaling interaction when each base station is directly connected, and completing the bearer transmission of user plane data (that is, service data) of each base station. Figure 3A shows the process of signaling interaction between the source base station and the target base station from the perspective of the control plane protocol stack of the I-X2 interface; Figure 3B shows the source base station and the target base station from the perspective of the user plane protocol stack of the I-X2 interface The process of exchanging service data between base stations.

上述建立数据直通通道的方式仅为举例说明，本实施例对如何建立数据直通通道不做限定。需要特别说明的是，上述网络架构中，各簇首基站中存储着归属于本簇首基站的所有基站的标识，即各簇首基站用于管理同一簇首内的所有基站。各簇首基站也具有类似于管理控制中心的能力，即建立其所管理的簇内的各基站之间的数据直通通道，这样可以减轻管理控制中心的负担，建立方法与上面所描述的相似，即由簇首基站下发连接信令和业务标识。各簇首基站之间的数据直通通道还是需要管理控制中心来建立。The foregoing manner of establishing a data direct channel is for illustration only, and this embodiment does not limit how to establish a data direct channel. It should be noted that in the above network architecture, each cluster head base station stores the identifiers of all base stations belonging to the cluster head base station, that is, each cluster head base station is used to manage all base stations in the same cluster head base station. Each cluster head base station also has the ability similar to the management control center, that is, to establish a direct data channel between the base stations in the cluster it manages, which can reduce the burden on the management control center. The establishment method is similar to that described above. That is, the cluster head base station issues connection signaling and service identifiers. The direct data channel between cluster head base stations still needs to be established by the management and control center.
需要指出的是，下面的“切换源基站”可以是发送方用户连接的基站，也可以是接收方用户连接的基站，相应的“切换目的基站”与切换源基站保持一致，可以是上述的源基站，也可以是上述的目标基站。具体来说，当切换源基站和切换目的基站均为源基站时，业务对端基站就是上述的目标基站，当切换源基站和切换目的基站均为目标基站时，业务对端基站就是上述的源基站。以下的“切换源基站标识”和“切换目的基站标识”均为特殊的标识，除了包含切换源基站和切换目的基站本身的标识之外，还可以添加特定的字符或字母以使各基站或管理控制中心识别该基站为切换源基站或者切换目的基站。It should be pointed out that the following "handover source base station" can be the base station connected by the sending user or the base station connected by the receiving user, and the corresponding "handover destination base station" is consistent with the handover source base station, which can be the above The base station may also be the aforementioned target base station. Specifically, when both the handover source base station and the handover destination base station are source base stations, the service peer base station is the above-mentioned target base station, and when the handover source base station and the handover destination base station are both target base stations, the service peer base station is the above-mentioned source base station. base station. The following "handover source base station identification" and "handover destination base station identification" are special identifications. In addition to including the identification of the handover source base station and the handover destination base station itself, specific characters or letters can also be added to make each base station or management The control center identifies the base station as a handover source base station or a handover target base station.
如图4所示，为根据本实施例的基站直通架构下的用户切换方法的流程示意图，包括：As shown in FIG. 4, it is a schematic flowchart of a user handover method under the base station direct architecture according to this embodiment, including:
步骤401，当切换源基站识别到用户需切换小区时，向对应的切换目的基站发起小区切换请求。Step 401, when the handover source base station recognizes that the user needs to switch cells, initiate a cell handover request to the corresponding handover target base station.
这里的切换源基站指的是用户当前正在连接的基站。切换源基站识别用户需切换小区的方法有很多种。例如，切换源基站接收用户上报的测量报告，根据测量报告中的信号功率和/或当前地理位置信息，判断用户是否需切换小区。当发现用户的信号功率较弱时，则很有可能该用户已经移动了位置到了另外一个基站的信号覆盖范围内，即对于另外一个基站其信号功率较强。此时，用户收集相邻基站的信号功率并形成测量报告，然后用户从各测量报告中选择一个信号功率值最大的基站作为切换目的基站，并将该切换目的基站的标识，即切换目的基站标识，发送给切换源基站；或者是用户收集相邻基站的信号功率并形成测量报告，并将包含能与该用户连接的各基站的信号功率的强度的测量报告发送给切换源基站，由切换源基站根据测量报告选择切换目的基站，或者是由切换源基站将用户上报的测量报告发送至管理控制中心，由管理控制中心根据测量报告选择切换目的基站。当然，切换源基站还可以直接检测用户的地理位置信息，或者接收用户每隔预设周期上报的地理位置信息，判断用户是否已需切换小区。切换源基站判断用户是否已经需切换小区的方法还有很多，本实施例中对此不做限定。Here, the handover source base station refers to the base station to which the user is currently connected. There are many methods for the handover source base station to identify that the user needs to handover the cell. For example, the handover source base station receives the measurement report reported by the user, and judges whether the user needs to handover the cell according to the signal power and/or current geographic location information in the measurement report. When the signal power of the user is found to be weak, it is likely that the user has moved to the signal coverage of another base station, that is, the signal power of the other base station is relatively strong. At this time, the user collects the signal power of adjacent base stations and forms a measurement report, and then the user selects a base station with the largest signal power value as the handover target base station from each measurement report, and records the handover target base station's identity, that is, the handover target base station identity , sent to the handover source base station; or the user collects the signal power of the adjacent base station and forms a measurement report, and sends the measurement report including the strength of the signal power of each base station that can be connected to the user to the handover source base station, and the handover source The base station selects the handover target base station according to the measurement report, or the handover source base station sends the measurement report reported by the user to the management control center, and the management control center selects the handover target base station according to the measurement report. Of course, the handover source base station can also directly detect the geographic location information of the user, or receive the geographic location information reported by the user every preset period, and determine whether the user needs to switch cells. There are many other methods for the handover source base station to determine whether the user needs to handover the cell, which is not limited in this embodiment.
小区切换请求可以包括用户的手机号码和IMEI（International MobileEquipment Identity，国际移动设备身份码），以使切换目的基站识别将要与哪个用户建立无线连接。The cell handover request may include the user's mobile phone number and IMEI (International Mobile Equipment Identity, International Mobile Equipment Identity), so that the handover destination base station identifies which user to establish a wireless connection with.
该步骤具体包括：This step specifically includes:
步骤401a，当切换源基站识别到用户需切换小区时，向切换源基站归属的切换源簇首基站发送切换目的基站标识，以使切换源簇首基站判断切换目的基站是否归属于切换源簇首基站。Step 401a, when the handover source base station recognizes that the user needs to switch cells, send the handover target base station identifier to the handover source cluster head base station to which the handover source base station belongs, so that the handover source cluster head base station judges whether the handover target base station belongs to the handover source cluster head base station.
由于各簇首基站中存储着其所管理的所有子基站的标识，因此，簇首基站能够根据所接收的切换目的基站标识判断切换目的基站是否归属于本簇首基站。还可以对切换目的基站标识添加特定的字符，以使簇首基站接收到切换目的基站标识时得知是要进行判断操作。具体方式现有技术中已经有很多，在此不再赘述。Since each cluster-head base station stores the identities of all sub-base stations it manages, the cluster-head base station can judge whether the handover-target base station belongs to its own cluster-head base station according to the received handover target base station ID. It is also possible to add specific characters to the handover target base station identifier, so that the cluster-head base station knows whether to perform a judgment operation when receiving the handover target base station identifier. There are already many specific manners in the prior art, which will not be repeated here.
步骤401b，当判断结果为切换目的基站归属于切换源簇首基站时，切换源基站直接向切换目的基站发送小区切换请求。Step 401b, when the judgment result is that the handover destination base station belongs to the handover source cluster-head base station, the handover source base station directly sends a cell handover request to the handover destination base station.
具体地，切换源基站和切换目的基站之间的如何建立数据直通通道以供发送小区切换请求可以根据步骤2011~2051所描述的过程建立，可以由切换源簇首基站直接下发连接信令以建立切换源基站和切换目的基站之间的数据直通通道，也可以由管理控制中心下发连接信令。该步骤中的“直接发送”意味着切换源基站向切换目的基站发送的小区切换请求不需要经过任何簇首基站。Specifically, how to establish a direct data channel between the handover source base station and the handover target base station for sending the cell handover request can be established according to the process described in steps 2011 to 2051, and the handover source cluster head base station can directly send connection signaling to To establish a direct data channel between the handover source base station and the handover destination base station, the management control center may also issue a connection signaling. "Directly sending" in this step means that the cell handover request sent by the handover source base station to the handover target base station does not need to go through any cluster head base station.
步骤401c，当判断结果为切换目的基站不归属于切换源簇首基站时，切换源基站通过切换源簇首基站向切换目的基站发送小区切换请求。Step 401c, when the judgment result is that the handover target base station does not belong to the handover source cluster head base station, the handover source base station sends a cell handover request to the handover target base station through the handover source cluster head base station.
该步骤具体可以为，当切换源簇首基站判断出切换目的基站并不归属于本簇首基站时，可以向管理控制中心发送查询请求，查询请求中包括业务标识、切换目的基站标识和切换源簇首基站标识，由管理控制中心根据预先存储的各基站标识判断该切换目的基站归属的切换目的簇首基站标识，并将该切换目的基站簇首标识返回给切换源簇首基站；或者是向管理控制中心发送查询请求后，由管理控制中心向该切换源簇首基站相邻的簇首基站转发该查询请求，当相邻的簇首基站确定自身为切换目的簇首基站时，即确定该切换目的基站归属于本簇首基站时，向管理控制中心返回查询响应，或者在建立了切换源簇首基站与切换目的簇首基站之间的数据直通通道的情况下直接向切换源簇首基站返回查询响应，查询响应中包括切换目的簇首基站标识和业务标识，以使切换源簇首基站获知切换目的基站归属于哪一个簇首基站。This step can specifically be that, when the handover source cluster head base station judges that the handover target base station does not belong to the cluster head base station, it can send a query request to the management control center, and the query request includes the service identification, the handover target base station identification and the handover source The cluster head base station identifier, the management control center judges the handover destination cluster head base station identifier of the handover destination base station according to the pre-stored identifiers of each base station, and returns the handover destination cluster head identifier to the handover source cluster head base station; or After the management control center sends the query request, the management control center forwards the query request to the cluster head base station adjacent to the handover source cluster head base station. When the adjacent cluster head base station determines that it is the handover destination cluster head base station, it will When the handover target base station belongs to the cluster head base station, it returns a query response to the management and control center, or directly sends the handover source cluster head base station to A query response is returned, and the query response includes the identity of the handover destination cluster head base station and the service identifier, so that the handover source cluster head base station knows which cluster head base station the handover destination base station belongs to.
步骤402，切换源基站接收切换目的基站返回的的小区切换响应，并转发给用户，以指示用户释放与切换源基站之间的无线连接，并建立与切换目的基站之间的无线连接。Step 402, the handover source base station receives the cell handover response returned by the handover target base station, and forwards it to the user, instructing the user to release the wireless connection with the handover source base station and establish a wireless connection with the handover target base station.
切换源基站如果接收到切换目的基站返回的小区切换响应之后，就说明切换目的基站已经做好相应的准备，即为用户预留出资源以与其建立无线连接。该小区切换响应可以包括切换目的基站的标识号。切换源基站将小区切换响应发送给用户，用户在接收到小区切换响应之后，释放与切换源基站之间的无线连接，接着，用户建立与切换目的基站之间的连接。If the handover source base station receives the cell handover response returned by the handover target base station, it indicates that the handover target base station has made corresponding preparations, that is, reserves resources for users to establish wireless connections with it. The cell handover response may include the identification number of the handover target base station. The handover source base station sends the cell handover response to the user, and after receiving the cell handover response, the user releases the wireless connection with the handover source base station, and then, the user establishes a connection with the handover target base station.
步骤403，当切换源基站接收到切换目的基站返回的小区切换成功响应时，向切换目的簇首基站发送第一判断信息，以使切换目的簇首基站根据第一判断信息中的业务对端基站标识判断业务对端基站是否归属于切换目的簇首基站，并根据判断结果触发切换目的基站和业务对端基站之间的当前数据直通通道建立流程，当前数据直通通道的两端分别为切换目的基站和业务对端基站。Step 403: When the handover source base station receives the cell handover success response returned by the handover target base station, it sends the first judgment information to the handover destination cluster head base station, so that the handover destination cluster head base station according to the service peer base station in the first judgment information Identify and judge whether the service peer base station belongs to the handover target cluster head base station, and trigger the current data direct channel establishment process between the handover target base station and the service peer base station according to the judgment result. The two ends of the current data direct channel are the handover target base stations respectively and business peer base stations.
切换源基站接收到切换目的基站返回的小区切换成功响应，即说明切换目的基站已经与用户建立无线连接。此时，可以向切换目的簇首基站发送第一判断信息，该第一判断信息中包括业务对端基站标识和切换目的基站标识，当然还可以包括业务标识，该业务标识可以存在于第一判断信息中，也可以在后续过程中由切换源基站向切换目的基站发送，具体可以按照实际需要进行设定。切换目的簇首基站接收到第一判断信息后，根据第一判断信息判断业务对端基站是否归属于本簇首基站内。并根据判断结果进行后续触发当前数据直通通道的建立流程。当前数据直通通道的两端分别为切换目的基站和业务对端基站，即切换目的基站接收发送方用户上传数据，且业务对端基站向接收方用户发送数据，或者业务对端基站接收发送方用户上传数据，且切换目的基站向接收方用户发送数据。The handover source base station receives the cell handover success response returned by the handover target base station, which means that the handover target base station has established a wireless connection with the user. At this time, the first judgment information may be sent to the handover target cluster head base station, and the first judgment information includes the service peer base station identifier and the handover destination base station identifier, and of course may also include a service identifier, which may exist in the first judgment The information may also be sent by the handover source base station to the handover target base station in a subsequent process, and may be specifically set according to actual needs. After receiving the first judgment information, the handover destination cluster head base station judges whether the service peer base station belongs to the cluster head base station according to the first judgment information. And according to the judgment result, the establishment process of the current data direct channel is subsequently triggered. The two ends of the current data direct channel are the handover target base station and the service peer base station respectively, that is, the handover target base station receives the data uploaded by the sender user, and the service peer base station sends data to the receiver user, or the service peer base station receives the sender user The data is uploaded, and the handover target base station sends the data to the receiving user.
切换目的基站与业务对端基站建立当前数据直通通道的过程与实施例一中源基站与目标基站建立数据直通通道的流程一致，在此不再赘述。The process of establishing the current data direct channel between the handover target base station and the service peer base station is the same as the process of establishing the data direct channel between the source base station and the target base station in Embodiment 1, and will not be repeated here.
需要特别指出的是，这里的切换目的基站与业务对端基站之间建立的当前数据直通通道很有可能与切换目的基站和业务对端基站之间建立的原有的数据直通通道有重复的部分，例如切换目的基站即为原有的数据直通通道中的一个中转基站，此时，可以选择重新建立切换目的基站与业务对端基站之间的当前数据直通通道，也可以选择根据原有的数据直通通道进行数据的传输，但是无论怎样，都属于本实施例的“建立”所包含的范围，因为本实施例中所建立的当前数据直通通道是以切换目的基站和业务对端基站为两端的。It should be pointed out that the current data direct channel established between the handover target base station and the service peer base station is likely to overlap with the original data direct channel established between the handover target base station and the service peer base station , for example, the handover target base station is a transit base station in the original data direct channel. At this time, you can choose to re-establish the current data direct channel between the handover target base station and the service peer base station, or you can choose to The direct channel is used for data transmission, but no matter what, it belongs to the scope of the "establishment" of this embodiment, because the current data direct channel established in this embodiment is based on the handover target base station and the service peer base station. .
根据本实施例的基站直通架构下的用户切换方法，使用户在切换小区时，通过基站之间直接进行切换路径的请求和操作，使得业务数据的传输路径及时地发生改变，不仅能够保证业务数据的正常传输，而且由于请求和业务数据的传输不用再经过核心网进行转发，一定程度上减小了用户进行基站切换所需要的时间。According to the user switching method under the base station direct connection architecture of this embodiment, when the user switches cells, the request and operation of the switching path are directly performed between the base stations, so that the transmission path of the service data is changed in time, which can not only ensure that the service data The normal transmission of requests and business data does not need to be forwarded through the core network, which reduces the time required for users to switch base stations to a certain extent.
实施例二Embodiment two
本实施例对实施例一的基站直通架构下的用户切换方法做进一步说明。This embodiment further describes the user switching method under the base station direct connection architecture of the first embodiment.
本实施例仅对步骤403中的切换目的簇首基站根据第一判断信息中的业务对端基站标识判断业务对端基站是否归属于切换目的簇首基站，并根据判断结果触发切换目的基站和业务对端基站之间的当前数据直通通道建立流程做进一步说明，其它步骤均与实施例一中的一致，在此不再赘述。In this embodiment, only for the handover destination cluster head base station in step 403, judge whether the service peer base station belongs to the handover destination cluster head base station according to the service peer base station identifier in the first judgment information, and trigger the handover destination base station and the service peer base station according to the judgment result. The flow of establishing the current direct data channel between the peer base stations will be further described, and other steps are consistent with those in Embodiment 1, and will not be repeated here.
具体地，切换目的簇首基站根据第一判断信息中的业务对端基站标识判断业务对端基站是否归属于切换目的簇首基站，并根据判断结果触发切换目的基站和业务对端基站之间的当前数据直通通道建立流程包括：Specifically, the handover target cluster head base station judges whether the service peer base station belongs to the handover target cluster head base station according to the service peer base station identifier in the first judgment information, and triggers the handover target base station and the service peer base station according to the judgment result. The current data direct channel establishment process includes:
步骤4031a，切换目的簇首基站接收第一判断信息，并根据第一判断信息中的业务对端基站标识判断业务对端基站是否归属于本簇首基站。Step 4031a, the handover target cluster head base station receives the first judgment information, and judges whether the service peer base station belongs to the cluster head base station according to the service peer base station identifier in the first judgment information.
第一判断信息中除了包括业务对端基站标识和切换目的基站标识之外，还可以包括业务标识和切换源基站标识。The first judgment information may include a service identifier and a handover source base station identifier in addition to the service peer base station identifier and the handover target base station identifier.
步骤4031b，当判断结果为是时，切换目的簇首基站直接建立切换目的基站和业务对端基站之间的当前数据直通通道。Step 4031b, when the judging result is yes, the handover target cluster-head base station directly establishes the current data direct channel between the handover target base station and the service peer base station.
由于第一判断信息中携带有业务对端基站标识和切换目的基站标识，因此切换目的簇首基站可以直接建立业务对端基站和切换目的基站之间的当前数据直通通道。该当前数据直通通道的具体建立流程可以与实施例一一致，所不同的是不再由管理控制中心下发连接信令，而是由切换目的簇首基站下发连接信令，这样可以减轻管理控制中心的负担。Since the first judgment information carries the identity of the service peer base station and the identity of the handover target base station, the handover target cluster-head base station can directly establish the current data direct channel between the service peer base station and the handover target base station. The specific establishment process of the current data direct channel can be consistent with the first embodiment, the difference is that the connection signaling is no longer issued by the management control center, but the connection signaling is issued by the handover target cluster head base station, which can reduce the The burden of managing the control center.
具体地，在4031b的当判断结果为是之后，即在切换目的簇首基站判断出业务对端基站归属于本簇首基站之后，且在切换目的簇首基站直接建立切换目的基站和业务对端基站之间的当前数据直通通道之前，还包括：Specifically, after the judging result in 4031b is yes, that is, after the handover target cluster head base station judges that the service peer base station belongs to its own cluster head base station, the handover target base station and the service peer base station are directly established at the handover target cluster head base station Before the current data pass-through channel between base stations, also include:
切换目的簇首基站根据第一判断信息中的切换源基站标识识别切换源基站是否归属于切换目的簇首基站；The handover target cluster head base station identifies whether the handover source base station belongs to the handover target cluster head base station according to the handover source base station identifier in the first judgment information;
当切换目的簇首基站识别到切换源基站归属于本簇首基站时，切换目的簇首基站获取切换源基站与业务对端基站之间的第一传输路径。When the handover destination cluster head base station recognizes that the handover source base station belongs to its own cluster head base station, the handover destination cluster head base station obtains the first transmission path between the handover source base station and the service peer base station.
此时，步骤4031b中的的切换目的簇首基站直接建立切换目的基站和业务对端基站之间的当前数据直通通道步骤具体包括：At this time, the handover target cluster head base station in step 4031b directly establishes the current data direct channel between the handover target base station and the service peer base station specifically includes:
步骤x1：切换目的簇首基站判断第一传输路径包含的基站数目是否大于切换目的基站与业务对端基站之间的第二传输路径所包含的基站数目；Step x1: the handover destination cluster head base station judges whether the number of base stations included in the first transmission path is greater than the number of base stations included in the second transmission path between the handover destination base station and the service peer base station;
步骤y1：当判断结果为是时，切换目的簇首基站根据第二传输路径执行直接建立切换目的基站和业务对端基站之间的当前数据直通通道。Step y1: When the judgment result is yes, the handover target cluster-head base station directly establishes the current data direct channel between the handover target base station and the service peer base station according to the second transmission path.
当切换源基站、切换目的基站和业务对端基站均归属于切换目的簇首基站时，即切换源簇首基站和切换目的簇首基站为同一个簇首基站时，切换目的簇首基站获取切换源基站与业务对端基站之间的第一传输路径，获取方式可以是先判断切换源基站与业务对端基站之间的数据直通通道是否由本切换目的簇首基站建立，如果判断结果为是，则从所存储的记录中获取第一传输路径，如果判断结果为否，可以向管理控制中心发送查询第一传输路径的消息，接收管理控制中心发送的第一传输路径；还可以是切换源基站根据第一判断信息中的切换源基站标识和业务对端基站标识就能够获取第一传输路径，这是由于，建立传输路径时并不是随机的，而是采取一定的策略，例如负载最轻原则、中转基站最少原则，因此，切换目的簇首基站可以根据切换源基站标识和业务对端基站标识从自身的路由表中直接获取第一传输路径。此外，切换目的基站根据自身的路由表，获取切换目的基站与业务对端基站之间的第二传输路径，然后再对比第一传输路径和第二传输路径。When the handover source base station, the handover destination base station and the service peer base station all belong to the handover destination cluster head base station, that is, when the handover source cluster head base station and the handover destination cluster head base station are the same cluster head base station, the handover destination cluster head base station obtains the handover The first transmission path between the source base station and the service peer base station may be obtained by first judging whether the data direct channel between the handover source base station and the service peer base station is established by the handover target cluster head base station, if the judgment result is yes, Then obtain the first transmission path from the stored records, if the judgment result is no, you can send a message to the management control center to inquire about the first transmission path, and receive the first transmission path sent by the management control center; it can also be the switching source base station The first transmission path can be obtained according to the identity of the handover source base station and the identity of the service peer base station in the first judgment information. This is because the establishment of the transmission path is not random, but a certain strategy is adopted, such as the principle of the lightest load , The minimum number of transit base stations, therefore, the handover destination cluster-head base station can directly obtain the first transmission path from its own routing table according to the handover source base station identifier and the service peer base station identifier. In addition, the handover target base station obtains the second transmission path between the handover target base station and the service peer base station according to its own routing table, and then compares the first transmission path with the second transmission path.
需要说明的是，切换源基站与业务对端基站之间建立起来的原有的数据直通通道可能需要经过0个、1个或多个子基站，按照先后顺序经过这些子基站所建立起来的路径即为第一传输路径。同样，切换目的基站与业务对端基站之间建立起来的当前数据直通通道可能需要经过0个、1个或多个子基站，按照先后顺序经过这些基站所建立起来的路径即为第二传输路径。当第一传输路径中所包含的基站数目大于第二传输路径中的基站数目时，就需要重新建立当前数据直通通道。如果当前数据直通通道中有部分与原有的数据直通通道有重叠的，可以采用原有的数据直通通道。例如，基站P与基站Q同属于第一传输路径和第二传输路径中相邻的两个基站，基站P与基站Q之间已经建立了与业务标识对应的数据直通通道，那么在建立当前数据直通通道时，可以采用基站P与基站Q之间原有的数据直通通道。在此之前，切换目的簇首基站可以选择是否向基站P和基站Q发送连接信令，当切换目的簇首基站向基站P和基站Q发送连接信令时，基站P和基站Q识别到已经建立了与该业务标识对应的数据直通通道时，可以选择不响应该连接信令；当切换目的簇首基站向基站P和基站Q不发送连接信令时，基站P或基站Q接收到与业务标识对应的业务数据时，基站P就通过原有的数据直通通道向基站Q发送或者由基站Q通过原有的数据直通通道向基站P进行发送。It should be noted that the original data direct channel established between the handover source base station and the service peer base station may need to pass through 0, 1 or more sub-base stations, and the path established through these sub-base stations in sequence is as the first transmission path. Similarly, the current data direct channel established between the handover target base station and the service peer base station may need to pass through 0, 1 or more sub-base stations, and the path established through these base stations in sequence is the second transmission path. When the number of base stations included in the first transmission path is greater than the number of base stations in the second transmission path, the current data direct channel needs to be re-established. If some of the current data direct channels overlap with the original data direct channels, the original data direct channels can be used. For example, base station P and base station Q belong to two adjacent base stations in the first transmission path and the second transmission path, and a data direct channel corresponding to the service identifier has been established between base station P and base station Q, then when establishing the current data For the direct channel, the original data direct channel between the base station P and the base station Q may be used. Before this, the handover target cluster head base station can choose whether to send connection signaling to base station P and base station Q. When the handover target cluster head base station sends connection signaling to base station P and base station Q, base station P and base station Q recognize that the When the data direct channel corresponding to the service identifier is selected, you can choose not to respond to the connection signaling; when the handover target cluster head base station does not send connection signaling to base station P and base station Q, base station P or base station Q receives the connection signaling corresponding to the service identifier. For corresponding service data, base station P sends to base station Q through the original data direct channel or base station Q sends to base station P through the original data direct channel.
另外，还需要指出的是，如果第一传输路径不大于第二传输路径时，就可以继续采用第一传输路径。具体为，业务对端基站接收发送方用户发送的业务数据，并通过与第一传输路径对应的数据直通通道发送至切换源基站，再由切换源基站通过与切换目的基站之间已经建立的切换数据直通通道发送至接收方用户，或者是切换目的基站接收发送方用户发送的业务数据并通过切换目的基站和切换源基站之间已经建立的切换数据直通通道向切换源基站发送，切换源基站接收到业务数据后，就通过与第一传输路径对应的数据直通通道发送至业务对端基站，再由业务对端基站发送至接收方用户。也就是说，第一传输路径对应的数据直通通道与切换数据直通通道合起来作为当前数据直通通道。In addition, it should be pointed out that if the first transmission path is not larger than the second transmission path, the first transmission path can continue to be used. Specifically, the service peer base station receives the service data sent by the sender user, and sends it to the handover source base station through the data direct channel corresponding to the first transmission path, and then the handover source base station passes the established handover data with the handover destination base station. The data direct channel is sent to the receiving user, or the handover destination base station receives the service data sent by the sending user and sends it to the handover source base station through the handover data direct channel established between the handover destination base station and the handover source base station, and the handover source base station receives After receiving the service data, it is sent to the service peer base station through the data direct channel corresponding to the first transmission path, and then sent to the receiving user by the service peer base station. That is to say, the data through channel corresponding to the first transmission path and the switched data through channel are combined as the current data through channel.
可选地，本实施例的方法在步骤y1之后还包括：Optionally, the method of this embodiment further includes after step y1:
切换目的簇首基站触发第一传输路径与第二传输路径中非重复部分的各基站之间的数据直通通道释放流程。The handover destination cluster-head base station triggers a data direct channel release procedure between base stations in the non-repetitive part of the first transmission path and the second transmission path.
具体举例来说，当第一传输路径从源基站到目标基站依次为：基站R1、基站R2、基站R3、基站R4，第二传输路径从源基站到目标基站依次为S1、R3、R4时，切换目的簇首基站通过对比第一传输路径和第二传输路径，能够识别到重复的部分为R3和R4，此时，向基站R1和基站R2发送数据直通通道释放信令，基站R1和基站R2接收到数据直通通道释放信令时，就向相邻的下一基站发送数据直通通道释放请求，当收到相邻的下一基站回复的数据直通通道释放响应时，就释放掉与业务标识对应的数据直通通道。例如，基站R1向基站R2发送数据直通通道释放请求，基站R2向基站R1返回数据直通通道释放响应，基站R1释放掉与基站R2之间的数据直通通道。For example, when the first transmission path from the source base station to the target base station is: base station R1, base station R2, base station R3, and base station R4, and the second transmission path from the source base station to the target base station is S1, R3, and R4, By comparing the first transmission path and the second transmission path, the handover destination cluster-head base station can identify the repeated parts as R3 and R4. At this time, it sends the data direct channel release signaling to the base station R1 and the base station R2, and the base station R1 and the base station R2 When receiving the data direct channel release signaling, it sends a data direct channel release request to the next adjacent base station, and when it receives the data direct channel release response replied by the adjacent next base station, it releases the data corresponding to the service identifier. data pass-through channel. For example, base station R1 sends a data direct channel release request to base station R2, base station R2 returns a data direct channel release response to base station R1, and base station R1 releases the data direct channel with base station R2.
当切换目的簇首基站通过对比第一传输路径和第二传输路径，如果识别到第一传输路径和第二传输路径中有非重复部分，可以向非重复部分中相应的基站发送数据直通通道释放信令，该数据直通通道释放信令可以包括第一传输路径中的相邻基站标识，以使相应的基站获知释放与哪个基站之间的数据直通通道。释放数据直通通道可以避免占用网络资源，进一步减轻了整个网络的负担。When the handover destination cluster head base station compares the first transmission path with the second transmission path, if it recognizes that there are non-repeated parts in the first transmission path and the second transmission path, it can send a data direct channel release to the corresponding base station in the non-repeated part Signaling, the data direct channel release signaling may include the identifier of the adjacent base station in the first transmission path, so that the corresponding base station knows which base station to release the data direct channel with. Releasing the data pass-through channel can avoid occupying network resources, further reducing the burden on the entire network.
步骤4031c，当判断结果为否时，切换目的簇首基站向管理控制中心发送第二判断信息，以触发管理控制中心执行当前数据直通通道建立流程，第二判断信息包括切换目的基站标识、切换源基站标识、业务对端基站标识和业务标识。Step 4031c, when the judgment result is no, the handover destination cluster-head base station sends second judgment information to the management control center to trigger the management control center to execute the current data direct channel establishment process, the second judgment information includes the handover destination base station identifier, the handover source Base station ID, service peer base station ID and service ID.
切换目的簇首基站所发送的第二判断信息中所包含的业务标识和切换源基站标识可以是包含在第一判断信息中的，也可以是在切换目的簇首基站识别到业务对端基站并不归属于本簇首基站时，向切换源基站返回相应的响应后再由切换源基站发送过来的，切换目的簇首基站接收到业务对端基站标识和切换源基站标识后添加到第一判断信息中形成第二判断信息。管理控制中心接收到该第二判断信息之后，可以先判断第一传输路径是否是由本管理控制中心建立的第一传输路径，如果是，可以从所存储的记录中直接获取第一传输路径，如果不是，则可以向切换源簇首基站发送查询第一传输路径的消息以接收切换源簇首基站发送的第一传输路径，或者根据第一判断信息中的切换源基站标识和业务对端基站标识就能够获取第一传输路径，这是由于，建立传输路径时并不是随机的，而是采取一定的策略，例如负载最轻原则、中转基站最少原则，因此，管理控制中心可以根据切换源基站标识和业务对端基站标识从自身的路由表中直接获取第一传输路径。The service identification and the handover source base station identification contained in the second judgment information sent by the handover destination cluster head base station may be included in the first judgment information, or it may be that the handover destination cluster head base station recognizes the service peer base station and When it does not belong to the cluster head base station, it returns the corresponding response to the handover source base station and then is sent by the handover source base station, and the handover destination cluster head base station receives the identity of the service peer base station and the identity of the handover source base station and adds it to the first judgment The second judgment information is formed in the information. After the management control center receives the second judgment information, it can first judge whether the first transmission path is the first transmission path established by the management control center, if yes, it can directly obtain the first transmission path from the stored records, if No, then a message to query the first transmission path can be sent to the handover source cluster head base station to receive the first transmission path sent by the handover source cluster head base station, or according to the handover source base station identifier and the service peer base station identifier in the first judgment information The first transmission path can be obtained. This is because the establishment of the transmission path is not random, but a certain strategy is adopted, such as the principle of the lightest load and the principle of the least transit base station. directly obtain the first transmission path from its own routing table with the identity of the service peer base station.
该步骤4031c中的管理控制中心执行当前数据直通通道建立流程具体包括：The management control center in step 4031c executes the current data direct channel establishment process specifically including:
步骤x2:管理控制中心获取获取切换源基站与业务对端基站之间的第一传输路径；Step x2: the management control center obtains the first transmission path between the handover source base station and the service peer base station;
步骤y2：管理控制中心判断第一传输路径包含的基站数目是否大于切换目的基站与业务对端基站之间的第二传输路径所包含的基站数目；管理控制中心根据切换目的基站标识与业务对端基站标识可以直接获取第二传输路径。Step y2: The management control center judges whether the number of base stations included in the first transmission path is greater than the number of base stations included in the second transmission path between the handover target base station and the service peer base station; The base station identifier can directly acquire the second transmission path.
步骤z2：当判断结果为是时，管理控制中心根据第二传输路径执行当前数据直通通道建立流程的操作。Step z2: When the judgment result is yes, the management control center executes the operation of the current data direct channel establishment process according to the second transmission path.
同样，本实施例的基站直通架构下的用户切换方法还包括：Similarly, the user switching method under the base station direct architecture of this embodiment also includes:
管理控制中心触发第一传输路径与第二传输路径中非重复部分的各基站之间的数据直通通道释放流程。The management control center triggers the data direct channel release procedure between the base stations in the non-duplicated part of the first transmission path and the second transmission path.
当管理控制中心通过对比第一传输路径和第二传输路径，如果识别到第一传输路径和第二传输路径中有非重复部分，可以向非重复部分中相应的基站发送数据直通通道释放信令，该数据直通通道释放信令可以包括第一传输路径中的相邻基站标识，以使相应的基站获知释放与哪个基站之间的数据直通通道。释放数据直通通道可以避免占用网络资源，进一步减轻了整个网络的负担。When the management control center compares the first transmission path with the second transmission path, if it recognizes that there is a non-repetitive part in the first transmission path and the second transmission path, it can send a data direct channel release signaling to the corresponding base station in the non-repetitive part , the data direct channel release signaling may include an identifier of an adjacent base station in the first transmission path, so that the corresponding base station knows which base station to release the data direct channel with. Releasing the data pass-through channel can avoid occupying network resources, further reducing the burden on the entire network.
根据本实施例的基站直通架构下的用户切换方法，通过判断切换源簇首基站与切换目的簇首基站是否为同一个簇首基站，当判断结果为是时，由切换目的簇首基站建立当前数据直通通道，能够减少管理控制中心的负担。According to the user handover method under the base station direct architecture of this embodiment, by judging whether the handover source cluster head base station and the handover destination cluster head base station are the same cluster head base station, when the judgment result is yes, the handover destination cluster head base station establishes the current The data direct channel can reduce the burden on the management control center.
实施例三Embodiment Three
本实施例对上述实施例的基站直通架构下的用户切换方法做进一步限定。This embodiment further limits the user handover method under the base station direct connection architecture of the foregoing embodiments.
本实施例中，对步骤401的当切换源基站识别到用户需切换小区时，向对应的切换目的基站发起小区切换请求的具体操作进行解释说明，其它步骤均与上述实施例中的一致，在此不再赘述。In this embodiment, the specific operation of initiating a cell switching request to the corresponding switching target base station when the switching source base station recognizes that the user needs to switch cells in step 401 is explained. Other steps are consistent with the above-mentioned embodiments. This will not be repeated here.
具体地，如下：Specifically, as follows:
步骤601、切换源基站向管理控制中心发送业务请求，业务请求中包括切换源基站标识、小区切换请求标识、切换目的基站标识和/或用户上传的测量报告，以使管理控制中心根据业务请求确定切换目的基站，并根据切换目标识的基站确定切换源基站和切换目的基站之间的第三传输路径。Step 601, the handover source base station sends a service request to the management control center, the service request includes the handover source base station identifier, the cell handover request identifier, the handover destination base station identifier and/or the measurement report uploaded by the user, so that the management control center can determine according to the service request The handover target base station, and determine the third transmission path between the handover source base station and the handover target base station according to the base station identified by the handover target.
切换源基站识别到用户需切换小区时，会通过与管理控制中心之间的接口向管理控制中心上报业务请求。该切换源基站可以为向发送方用户连接的基站或接收方用户连接的基站。When the switching source base station recognizes that the user needs to switch cells, it will report the service request to the management control center through the interface with the management control center. The handover source base station may be a base station connected to the sending user or a base station connected to the receiving user.
步骤602、切换源基站接收管理控制中心发送的连接建立信令，以使切换源基站和切换目的基站根据连接建立信令建立起数据直通通道，连接建立信令包括切换源基站地址、切换目的基站地址和第三传输路径。Step 602, the handover source base station receives the connection establishment signaling sent by the management control center, so that the handover source base station and the handover destination base station establish a data direct channel according to the connection establishment signaling, and the connection establishment signaling includes the handover source base station address, the handover destination base station address and third transmission path.
当确定出切换源基站和切换目的基站之后，管理控制中心根据预设选择策略为切换源基站和切换目的基站从多条路径中选择一条路径作为建立数据直通通道时使用的第三传输路径。其中，预设选择策略可以是根据最短路径原则进行选择的策略，也可以是根据路径负载最轻原则进行选择的策略等，在本实施例中不做限定。After the handover source base station and the handover destination base station are determined, the management control center selects a path from multiple paths for the handover source base station and the handover destination base station according to a preset selection strategy as the third transmission path used when establishing the direct data channel. Wherein, the preset selection policy may be a policy selected according to the principle of the shortest path, or a policy selected according to the principle of the lightest path load, etc., which is not limited in this embodiment.
当确定出切换源基站、切换目的基站以及第三传输路径后，管理控制中心分别向切换源基站和切换目的基站发送连接建立信令，并将切换源基站地址、切换目的基站地址和选择的第三传输路径携带在连接建立信令中，以使切换源基站和切换目的基站根据连接建立信令中的信息建立切换数据直通通道。After determining the handover source base station, the handover destination base station, and the third transmission path, the management control center sends connection establishment signaling to the handover source base station and the handover destination base station respectively, and sends the address of the handover source base station, the address of the handover destination base station, and the selected first The three transmission paths are carried in the connection establishment signaling, so that the handover source base station and the handover destination base station establish a handover data direct channel according to the information in the connection establishment signaling.
步骤603、切换源基站通过切换数据直通通道向切换目的基站发送小区切换请求。Step 603, the handover source base station sends a cell handover request to the handover target base station through the handover data direct channel.
当切换源基站和切换目的基站之间建立起数据直通通道后，切换源基站和切换目的基站之间的小区切换请求信息就可以通过数据直通通道进行传输，而无需由切换源基站或切换目的基站通过骨干传输网传送给核心网的中心控制节点，再由中心控制节点统一进行转发了。After the data direct channel is established between the handover source base station and the handover target base station, the cell handover request information between the handover source base station and the handover target base station can be transmitted through the data direct channel without the handover source base station or the handover target base station. It is transmitted to the central control node of the core network through the backbone transmission network, and then forwarded by the central control node in a unified manner.
