Technical field

本发明涉及通讯领域，尤其涉及一种数据本地交换方法、装置和***。 The present invention relates to the field of communications, and in particular, to a data local exchange method, apparatus, and system.

背景技术 Background technique

随着通讯技术的发展，人们越来越多的使用通信网络进行信息的交换。通常的通信业务的交换都要经过核心网来完成，若通信双方终端处于同一个基站下，业务数据仍经由核心网转发，不仅浪费传输成本，还带来不必要的延时，因此提出了本地交换技术。 With the development of communication technologies, people are increasingly using communication networks for information exchange. The exchange of the usual communication services is performed through the core network. If the terminals of the communication terminals are under the same base station, the service data is still forwarded through the core network, which not only wastes transmission costs but also introduces unnecessary delays. Exchange technology.

现有的本地交换技术中，基站对每个上行数据包都进行解析，得到每个数据包的源 IP ( Internet Protocol 互联网协议 )地址、目的 IP地址和业务类型，然后基站根据业务类型判断该业务是否支持本地交换，并根据源 IP地址和目的 IP地址判断双方终端是否在本基站下，如果两次判断都符合本地交换的要求，则基站执行本地交换。 In the existing local switching technology, the base station parses each uplink data packet to obtain a source IP (Internet Protocol Internet Protocol) address, a destination IP address, and a service type of each data packet, and then the base station determines the service according to the service type. Whether the local exchange is supported, and whether the two terminals are under the base station according to the source IP address and the destination IP address, if the two judgments meet the requirements of the local exchange, the base station performs local exchange.

现有本地交换技术中，基站收到上行数据时，必须通过检测该上行数据对应的 IP地址判断该数据的发送端与接收端是否处于该基站下，因此，基站需要对每个上行数据包解析，同时，还要判断该数据对应的业务类型是否支持本地交换，由此增大了基站的工作量，有效性不高。 In the existing local switching technology, when receiving the uplink data, the base station must determine whether the transmitting end and the receiving end of the data are under the base station by detecting the IP address corresponding to the uplink data. Therefore, the base station needs to parse each uplink data packet. At the same time, it is also necessary to determine whether the service type corresponding to the data supports local exchange, thereby increasing the workload of the base station, and the effectiveness is not high.

图 2示出了本发明一种数据本地交换方法的实施例一的流程图，包括：步骤 201，网络侧在同请求端建立承载过程中，获取第一地址信息，并将该第一地址信息发送至请求端所属的基站或网关；以及，在同接收端建立承载过程中，获取第二地址信息，并将该第二地址信息发送至接收端所属的基站或网关； FIG. 2 is a flowchart of Embodiment 1 of a data local exchange method according to the present invention, including: Step 201: A network side acquires first address information, and obtains the first address information in a bearer process with a requesting end. Sending to the base station or the gateway to which the requesting end belongs; and, in the process of establishing a bearer with the receiving end, acquiring the second address information, and transmitting the second address information to the base station or gateway to which the receiving end belongs;

在步骤 201中，该地址信息可以为请求端和接收端的 IP地址和端口号。其中，若请求端或接收端承载上的业务支持本地交换，网络侧设备移动管理实体 MME同请求端建立承载，获取第一地址信息包括网络侧设备移动管理实体 MME在同请求端建立承载过程中获取请求端 IP地址、请求端端口号和接收端 IP地址、接收端端口号，并将获取的地址信息发送至请求端所属的基站或网关；获取第二地址信息包括，网络侧设备移动管理实体 MME在同接收端建立承载过程中获取接收端 IP地址、接收端端口号和请求端 IP地址、请求端端口号，并将获取的地址信息发送至接收端所属的基站或网关。 In step 201, the address information may be an IP address and a port number of the requesting end and the receiving end. The network side device mobility management entity MME establishes a bearer with the requesting end, and the network side device mobility management entity MME establishes a bearer relationship with the requesting end, if the service on the requesting end or the receiving end carries the local switching. Obtaining the requesting end IP address, the requesting port number, the receiving end IP address, and the receiving port number, and sending the obtained address information to the base station or gateway to which the requesting end belongs; obtaining the second address information includes: the network side device mobility management entity The MME obtains the receiving end IP address, the receiving port number, the requesting end IP address, and the requesting port number in the process of establishing the bearer with the receiving end, and sends the obtained address information to the base station or gateway to which the receiving end belongs.

步骤 201 中，获取第一地址信息包括，接入网设备基站或网关在同请求端建立承载过程中，从非接入层消息中获取请求端 IP地址、请求端端口号和接收端 IP地址、接收端端口号；获取第二地址信息包括，接入网设备基站或网关在同接收端建立承载过程中，从非接入层消息中获取请求端 IP地址、请求端端口号和接收端 IP地址、接收端端口号。 In step 201, the obtaining the first address information includes: when the base station or the gateway of the access network device establishes a bearer with the requesting end, acquiring the requesting end IP address, the requesting port number, and the receiving end IP address from the non-access stratum message, The receiving port number; obtaining the second address information includes: the access network device base station or the gateway acquires the requesting end IP address, the requesting port number, and the receiving end IP address from the non-access stratum message during the establishment of the bearer with the receiving end , the receiving port number.

步骤 202，当该第一地址信息和该第二地址信息相同时，将请求端和接收端绑定； Step 202: When the first address information and the second address information are the same, the requesting end and the receiving end End binding

具体包括将请求端 IP地址及端口号、接收端 IP地址及端口号、请求端承载 ID ( Identity 身份标识）、接收端承载 ID绑定；即将请求端承载 ID同接收端承载 ID绑定，请求端承载 ID是请求端的 IP地址上的端口号以及该端口号上对应业务所建立的承载 ID, 接收端承载 ID是接收端的 IP地址上的端口号以及该端口号上对应业务所建立的承载 ID。 Specifically, the IP address and port number of the requesting end, the IP address and port number of the receiving end, the bearer ID (identity identifier) of the requesting end, and the bearer ID of the receiving end are bound; the bearer ID of the requesting end is bound to the bearer ID of the receiving end, and the request is The port bearer ID is the port number on the IP address of the requesting end and the bearer ID established by the corresponding service on the port number. The bearer ID of the receiving end is the port number on the IP address of the receiving end and the bearer ID established by the corresponding service on the port number. .

当请求端承载 ID与一个接收端承载 ID绑定时，网络侧的基站或网关直接在该接收端承载上转发请求端承载上的上行数据包； When the bearer ID of the requesting end is bound to the bearer ID of the receiving end, the base station or the gateway on the network side forwards the uplink data packet on the bearer of the requesting end directly on the bearer of the receiving end;

或者当接收端承载 ID与一个请求端承载 ID绑定时，网络侧的基站或网关直接在该请求端承载上转发接收端承载上的上行数据包。 Or when the bearer ID of the receiving end is bound to a bearer ID of the requesting end, the base station or the gateway of the network side forwards the uplink data packet on the bearer of the receiving end directly on the bearer of the requesting end.

步骤 203，对绑定的请求端或接收端在绑定承载上发送的数据执行本地交换。 Step 203: Perform local exchange on the data sent by the bound requesting end or the receiving end on the binding bearer.

当请求端承载 ID与多个接收端承载 ID绑定时，网络侧的基站或网关解析请求端承载上的上行数据包，获得该数据包的接收端 IP地址、接收端端口号和对应的接收端承载 ID后，在接收端承载上转发该上行数据包； When the bearer ID of the requesting end is bound to the bearer ID of multiple receiving ends, the base station or the gateway on the network side parses the uplink data packet on the bearer of the requesting end, and obtains the IP address of the receiving end of the data packet, the port number of the receiving end, and the corresponding receiving. After the bearer carries the ID, the uplink data packet is forwarded on the bearer of the receiving end;

当接收端承载 ID与多个请求端承载 ID绑定时，网络侧的基站或网关解析接收端承载上的上行数据包，获得该数据包的请求端 IP地址、请求端端口号和对应的请求端承载 ID后，在请求端承载上转发该上行数据包。 When the bearer ID of the receiving end is bound to the bearer ID of multiple requesting ends, the base station or the gateway on the network side parses the uplink data packet on the bearer of the receiving end, and obtains the IP address of the requesting end, the port number of the requesting end, and the corresponding request of the data packet. After the bearer carries the ID, the uplink data packet is forwarded on the requesting end bearer.

在实施步骤 201 时，获取该第一、第二地址信息的工作可以由网络侧设备移动管理实体 MME、基站或网关来完成，该地址信息可以包括请求端和接收端的 IP地址和端口号，若基站或网关接收的第一地址信息与第二地址信息相同，则请求端和接收端属于同一个基站或网关，将请求端和接收端绑定后，对请求端或接收端在承载上发送的数据执行本地交换，这样基站就不需要对每个上行数据包进行解析来获得数据包包含的地址信息，减少了基站对数据包本地交换进行匹配的次数，提高了有效性，减少了基站的工作量。图 3 示出的本发明方法的具体实施例二中，获取地址信息的工作由网络侧设备移动管理实体 MME完成，执行本地交换的工作由基站来完成，包括： When the step 201 is implemented, the operation of acquiring the first and second address information may be performed by the network side device mobility management entity MME, the base station, or the gateway, where the address information may include an IP address and a port number of the requesting end and the receiving end, if The first address information received by the base station or the gateway is the same as the second address information, and the requesting end and the receiving end belong to the same base station or gateway, and after the requesting end and the receiving end are bound, the requesting end or the receiving end sends the bearer on the bearer. The data performs local exchange, so that the base station does not need to parse each uplink data packet to obtain address information contained in the data packet, which reduces the number of times the base station matches the local exchange of the data packet, improves the effectiveness, and reduces the work of the base station. the amount. In the second embodiment of the method of the present invention, the operation of obtaining the address information is performed by the network side device mobility management entity MME, and the local exchange is performed by the base station, including:

步骤 301，网络侧设备移动管理实体 MME在同请求端建立承载过程中获取地址信息； Step 301: The network side device mobility management entity obtains address information in the process of establishing a bearer with the requesting end.

该获取的地址信息具体可以是请求端 IP地址、请求端端口号和接收端 IP 地址、接收端端口号，并将获取的地址信息发送至请求端所属的基站。 The obtained address information may specifically be a requesting end IP address, a requesting port number, and a receiving end IP. The address, the receiving port number, and the obtained address information is sent to the base station to which the requesting end belongs.

在 MME同请求端建立承载之前，还包括 MME预处理的步骤 3011 ; 步骤 3011 中， MME向核心网查询该承载上的业务是否支持本地交换，若承载上的业务能支持本地交换，则 MME在承载建立过程中获取请求端的 IP地址和端口号，同时获取接收端的 IP地址和端口号，这里获取的接收端的 IP地址和端口号可能有多个。 Before the MME establishes a bearer with the requesting end, the method further includes a step 3011 of the MME pre-processing; in step 3011, the MME queries the core network whether the service on the bearer supports the local exchange, and if the service on the bearer can support the local exchange, the MME is The IP address and port number of the requesting end are obtained during the bearer establishment process, and the IP address and port number of the receiving end are obtained. The IP address and port number of the receiving end obtained here may be multiple.

步骤 302，基站判断是否执行本地交换； Step 302: The base station determines whether to perform local exchange.

MME将获取的请求端的 IP地址和端口号，以及接收端的 IP地址和端口号发送给请求端所属的基站，基站将这些地址信息保存，当基站再次收到 MME发送的接收端 IP地址和端口号，以及请求端的 IP地址和端口号信息，基站判断新收到的 IP地址和端口号等信息是否已经保存，如果已经保存，则说明通信双方终端接入同一个基站，则支持本地交换，如果不支持本地交换，则按照现有技术中通过核心网转发通信业务，具体流程不再赘述。 The MME sends the obtained IP address and port number of the requesting end, and the IP address and port number of the receiving end to the base station to which the requesting end belongs. The base station saves the address information, and when the base station receives the receiving end IP address and port number sent by the MME again. And the IP address and the port number information of the requesting end, the base station determines whether the newly received IP address and the port number have been saved, and if it has been saved, the terminal of the communication terminal accesses the same base station, and supports local exchange, if not If the local exchange is supported, the communication service is forwarded through the core network according to the prior art, and the specific process is not described here.

在实施步骤 302时，基站再次收到的 MME发送的信息是 MME同接收端建立承载的过程中获取的，当接收端是同上述请求端进行通信时，并且请求端和接收端在同一个基站下，那么基站再次收到的信息同步骤 301 中 MME 获取并发给基站的信息相同；当接收端不是同上述请求端进行通信，但接收端同请求端在同一个基站下，那么基站再次收到的信息同步骤 301 中 MME 获取并发给基站的信息就不相同； When the step 302 is performed, the information sent by the MME received by the eNB is obtained in the process of establishing a bearer between the MME and the receiving end. When the receiving end communicates with the requesting end, the requesting end and the receiving end are in the same base station. Then, the information received by the base station is the same as the information obtained by the MME in step 301 to be sent to the base station. When the receiving end does not communicate with the requesting end, but the receiving end is in the same base station as the requesting end, the base station receives the same again. The information is different from the information obtained by the MME in step 301 and sent to the base station;

步骤 303，基站将支持本地交换的通信双方终端绑定； Step 303: The base station binds the terminal of the communication terminal that supports the local exchange;

具体包括将下述的参数进行绑定（请求端 IP地址及端口号，接收端 IP地址及端口号，请求端承载 ID, 接收端承载 ID ), 通常情况下一个终端对应一个 IP地址，一个终端可以有多个端口号，每个端口号对应一个业务，而且每个终端可以根据业务需求建立多个承载，每个承载有唯一的承载 ID; 所以在绑定通信终端的时候，要将请求端的 IP地址和端口号以及该端口号上对应业务所建立的承载 ID同接收端的 IP地址和端口号以及该端口号上对应业务所建立的承载 ID对应绑定。在具体设置时，可以将请求端承载 ID上业务的转发地址设为接收端 IP地址和接收端端口号；将接收端承载 ID上业务的转发地址设为请求端 IP地址和请求端端口号。其中绑定的承载 ID可以是终端和基站间的无线承载 ID。由于请求端的某一个承载上的业务转发地址可以是多个接收端各自的 IP地址和端口号，因此请求端的一个承载 ID可能与多个接收端的承载 ID绑定。 Specifically, the following parameters are bound (requesting end IP address and port number, receiving end IP address and port number, requesting end bearer ID, receiving end carrying ID), usually one terminal corresponds to one IP address, one terminal There may be multiple port numbers, each port number corresponding to one service, and each terminal may establish multiple bearers according to service requirements, each bearer having a unique bearer ID; therefore, when binding the communication terminal, the requester end The IP address and port number and the bearer ID established by the corresponding service on the port number are bound to the IP address and port number of the receiving end and the bearer ID established by the corresponding service on the port number. In a specific setting, the forwarding address of the service on the bearer ID of the requesting end may be set as the receiving end IP address and the receiving port number; and the forwarding address of the service on the receiving end bearer ID is set as the requesting end IP address and the requesting port number. The bearer ID to be bound may be a radio bearer ID between the terminal and the base station. Because the service forwarding address on a certain bearer of the requesting end can be more Each receiving end has its own IP address and port number, so a bearer ID of the requesting end may be bound to the bearer ID of multiple receiving ends.

步骤 304，基站执行本地交换。 Step 304: The base station performs local exchange.

请求端通过请求端承载 ID将数据包发送给基站，基站识别到该数据包是来自绑定的承载 ID上的，于是基站将请求端承载 ID同绑定信息匹配，如果请求端承载 ID只与一个接收端承载 ID绑定，则基站直接在该接收端承载上向接收端转发该数据包；若请求端承载 ID与多个接收端承载 ID绑定，则基站解析收到的数据包，获得该数据包的目的 IP地址及端口号，通过获得的目的 IP地址及端口号判断数据包的转发地址（即接收端承载 ID )并转发到对应的接收端。 The requesting end sends the data packet to the base station by using the bearer ID of the requesting end, and the base station recognizes that the data packet is from the bearer ID of the binding, and the base station matches the bearer ID of the requesting end with the binding information, if the requesting end carries the ID only A receiving end carries an ID binding, and the base station directly forwards the data packet to the receiving end on the receiving end bearer; if the requesting end bearer ID is bound to multiple receiving end bearer IDs, the base station parses the received data packet, and obtains The destination IP address and port number of the data packet, the destination IP address and the port number of the obtained packet are used to determine the forwarding address of the data packet (ie, the receiving end bearer ID) and forwarded to the corresponding receiving end.

在执行步骤 304时，如果接收端通过接收端承载 ID将数据包发送给基站，基站识别到该数据包是来自绑定的承载 ID上的，基站将接收端承载 ID同绑定信息匹配，如果接收端承载 ID只与一个请求端承载 ID绑定，则基站直接在该请求端承载上向请求端转发该数据包。当接收端承载 ID与多个请求端承载 ID绑定时，基站或网关解析接收端承载上的上行数据包，得到该数据包的请求端 IP地址、请求端端口号和对应的请求端承载 ID, 在请求端承载上转发该上行数据包。 When performing step 304, if the receiving end sends the data packet to the base station by using the bearer ID of the receiving end, the base station recognizes that the data packet is from the bearer ID of the binding, and the base station matches the bearer ID of the receiving end with the binding information, if The bearer ID of the receiving end is only bound to one bearer ID of the requesting end, and the base station directly forwards the data packet to the requesting end on the bearer of the requesting end. When the bearer ID of the receiving end is bound to the bearer ID of multiple requesting ends, the base station or the gateway parses the uplink data packet on the bearer of the receiving end, and obtains the IP address of the requesting end, the port number of the requesting end, and the corresponding requesting end bearer ID of the data packet. Forwarding the upstream data packet on the requesting side bearer.

在上述具体方案实施的过程中，也包括有通信双方终端同 MME建立承载的过程，基站收到 MME发送的建立承载请求后同请求端建立无线承载，请求端响应该建立承载请求，基站将承载建立响应信息发送给 MME, 请求端的承载建立完成。同样的， MME将建立承载请求发给接收端所属的基站，该基站同接收端建立无线承载，接收端响应该建立承载请求，基站将承载建立响应信息发送给 MME, 接收端的承载建立完成。 In the process of implementing the foregoing specific solution, the process includes the process of establishing a bearer between the terminal of the communication terminal and the MME. After receiving the bearer request sent by the MME, the base station establishes a radio bearer with the requesting end, and the requesting end responds to the setup bearer request, and the base station carries the bearer. The establishment response information is sent to the MME, and the bearer establishment of the requesting end is completed. Similarly, the MME sends a bearer request to the base station to which the receiving end belongs, and the base station establishes a radio bearer with the receiving end, and the receiving end responds to the setup bearer request, and the base station sends the bearer setup response information to the MME, and the bearer establishment of the receiving end is completed.

MME完成获取地址信息的工作并发送给基站，这样，基站只需要对收到的地址信息进行匹配就可以判断通信双方终端是否可以执行本地交换，减轻了基站的工作量； MME在同通信终端建立承载的过程中获取地址信息，而不是盲目的对所有上行数据包进行检测，提高了本地交换匹配的有效性。 The MME completes the work of obtaining the address information and sends it to the base station. In this way, the base station only needs to match the received address information to determine whether the communication terminal can perform local exchange, thereby reducing the workload of the base station; the MME establishes with the communication terminal. The address information is obtained in the process of bearer, instead of blindly detecting all uplink data packets, which improves the effectiveness of local exchange matching.

上面的实施例中，基站对通信双方终端是否支持本地交换进行判断，若通信双方终端支持本地交换，基站对通信双方终端进行绑定后执行本地交换；，通信双方终端也可以接入同一个网关，下面给出的本发明方法的实施例三是针对同一个网关下接入不同的终端之间业务的本地交换的情况，如图 4 所示，该实施例具体包括： In the above embodiment, the base station determines whether the communication terminal supports the local exchange. If the communication terminal supports local exchange, the base station performs binding on the communication terminal and performs local exchange; the communication terminal can also access the same gateway. , an embodiment of the method of the invention given below The third embodiment is directed to the local exchange of services between different terminals in the same gateway. As shown in FIG. 4, the embodiment specifically includes:

步骤 401，网络侧设备移动管理实体 MME在同请求端建立承载过程中获取请求端与接收端的地址信息，并将获取的该地址信息发送至请求端所属的网关； Step 401: The network side device mobility management entity obtains the address information of the requesting end and the receiving end in the process of establishing a bearer with the requesting end, and sends the obtained address information to the gateway to which the requesting end belongs;

该地址信息可以包括请求端的 IP地址、请求端端口号和接收端 IP地址、接收端端口号，网关将建立承载请求发给请求端所属的基站，然后由基站将建立无线承载请求转发给请求端，请求端响应该建立无线承载请求，基站将承载建立响应信息发送给网关，由网关将该承载建立响应信息转发给 MME, 请求端的承载建立完成；同样的，网关将建立承载请求发给接收端所属的基站，该基站将建立无线承载请求转发给接收端，接收端响应该建立无线承载请求，基站将承载建立响应信息发送给网关，网关将该承载建立响应信息转发给 MME，接收端的承载建立完成。 The address information may include an IP address of the requesting end, a requesting port number, a receiving end IP address, and a receiving end port number. The gateway sends a bearer request to the base station to which the requesting end belongs, and then the base station forwards the establishing radio bearer request to the requesting end. The requesting end responds to the establishment of the radio bearer request, and the base station sends the bearer setup response information to the gateway, and the gateway forwards the bearer setup response information to the MME, and the bearer of the requesting end is established. Similarly, the gateway sends a bearer request to the receiving end. The base station, the base station forwards the radio bearer request to the receiving end, and the receiving end responds to the establishing the radio bearer request, and the base station sends the bearer setup response information to the gateway, and the gateway forwards the bearer setup response information to the MME, and the bearer of the receiving end is established. carry out.

在 MME请求建立承载之前，还包括步骤 4011 : MME预处理；具体包括 MME向核心网查询该承载上的业务是否支持本地交换，若承载上的业务能支持本地交换，则 MME在承载建立过程中获取请求端与接收端的地址信息，包括请求端的 IP地址和端口号，接收端的 IP地址和端口号，这里获取的接收端的 IP地址和端口号可能有多个。 Before the MME requests to establish a bearer, the method further includes: Step 4011: MME pre-processing; specifically, the MME queries the core network whether the service on the bearer supports local exchange, and if the service on the bearer can support local exchange, the MME is in the bearer establishment process. Obtain the address information of the requesting end and the receiving end, including the IP address and port number of the requesting end, the IP address and port number of the receiving end, and the IP address and port number of the receiving end obtained here may be multiple.

步骤 402，网关判断是否能进行本地交换； Step 402: The gateway determines whether local switching can be performed.

MME将获取的请求端的地址信息发送给请求端所属的网关后，网关保存该地址信息，当网关再次收到 MME发送的接收端与请求端的地址信息时，该地址信息包括接收端 IP地址和端口号以及请求端 IP地址和端口号，网关判断新收到的 IP地址和端口号是否已经保存，如果已经保存，则说明通信双方终端接入同一个网关，即支持本地交换，如果不支持本地交换，则按照现有技术中通过核心网转发通信业务，具体流程不再赘述。 After the MME sends the obtained address information of the requesting end to the gateway to which the requesting end belongs, the gateway saves the address information. When the gateway receives the address information of the receiving end and the requesting end sent by the MME again, the address information includes the receiving end IP address and the port. The number and the IP address and port number of the requesting end. The gateway determines whether the newly received IP address and port number have been saved. If it has been saved, the terminal of the communication terminal accesses the same gateway, that is, supports local switching, if local switching is not supported. Then, the communication service is forwarded through the core network according to the prior art, and the specific process is not described again.

步骤 403，网关将判断得到的支持本地交换的通信双方终端绑定；具体指将请求端 IP地址及端口号和接收端 IP地址及端口号绑定，请求端承载 ID，和接收端承载 ID绑定，其中绑定的承载 ID指基站和网关间的承载 ID。由于请求端的某一个承载上可能向多个接收端发起业务，因此请求端的一个承载 ID可能与多个接收端的承载 ID绑定。步骤 404，网关执行本地交换。 In step 403, the gateway binds the terminal of the communication terminal that supports the local exchange; specifically, the IP address and port number of the requesting end are bound to the IP address and port number of the receiving end, and the bearer ID of the requesting end is bound to the bearer ID of the receiving end. The bearer ID of the binding refers to the bearer ID between the base station and the gateway. Since a certain bearer of the requesting end may initiate a service to multiple receiving ends, a bearer ID of the requesting end may be bound to a bearer ID of multiple receiving ends. In step 404, the gateway performs local exchange.

请求端通过请求端承载 ID将上行数据包发送到网关，网关收到该上行数据包后，识别该数据包是绑定的承载 ID上发送的，于是网关将请求端承载 ID 同绑定信息匹配，如果请求端承载 ID只与一个接收端承载 ID绑定，则网关直接在接收端承载上向接收端转发该数据包；若请求端承载 ID与多个接收端承载 ID绑定，则网关解析收到的数据包，获得该数据包的目的 IP地址及端口号，通过获得的目的 IP地址及端口号判断数据包的转发地址，即接收端承载 ID, 并转发到对应的接收端。在上述第三个具体实施例中， MME完成获取地址信息的工作并发送给网关，由网关来判断通信双方终端是否可以执行本地交换，并且由网关来执行地址交换，大大减轻了基站的工作量。 The requesting end sends the uplink data packet to the gateway by using the bearer ID of the requesting end. After receiving the uplink data packet, the gateway identifies that the data packet is sent on the bearer ID of the binding, and the gateway matches the bearer ID of the requesting end with the binding information. If the requesting end bearer ID is only bound to one receiving end bearer ID, the gateway directly forwards the data packet to the receiving end on the receiving end bearer; if the requesting end bearer ID is bound to multiple receiving end bearer IDs, the gateway parses The received data packet obtains the destination IP address and port number of the data packet, and determines the forwarding address of the data packet by using the obtained destination IP address and port number, that is, the receiving end carries the ID, and forwards it to the corresponding receiving end. In the foregoing third specific embodiment, the MME completes the work of acquiring the address information and sends the information to the gateway, and the gateway determines whether the communication terminal can perform the local exchange, and the gateway performs the address exchange, thereby greatly reducing the workload of the base station. .

上面的实施例中由网关对通信双方终端是否支持本地交换进行判断，并由网关对通行双方终端进行绑定，并执行本地交换。网关的作用可以是起到转发的功能，具体实施方式可以参见图 5示出的本发明方法的实施例四，包括： In the above embodiment, the gateway determines whether the communication terminal supports the local exchange, and the gateway binds the two terminals to each other and performs local exchange. The function of the gateway may be a function of forwarding. For a specific implementation, refer to Embodiment 4 of the method of the present invention shown in FIG. 5, including:

步骤 501，网络侧设备移动管理实体 MME在同请求端建立承载过程中获取请求端与接收端的地址信息，并将获取的该地址信息发送至请求端所属的基站； Step 501: The network side device mobility management entity MME obtains the address information of the requesting end and the receiving end in the process of establishing a bearer with the requesting end, and sends the obtained address information to the base station to which the requesting end belongs;

该地址信息包括请求端 IP地址、请求端端口号和接收端 IP地址、接收端端口号， MME向网关发送建立承载请求，网关将建立承载请求转发给请求端所属的基站，然后基站将建立无线承载请求转发给请求端，请求端响应该建立无线承载请求，基站将承载建立响应信息发送给网关，网关再将该承载建立响应信息转发给 MME, 请求端的承载建立完成；同样的，网关将建立承载请求发给接收端所属的基站，该基站将建立无线承载请求发送给接收端，接收端响应该建立无线承载请求，基站将承载建立响应信息发送给网关，网关再将该承载建立响应信息转发给 MME, 接收端的承载建立完成。 The address information includes a requesting end IP address, a requesting port number, a receiving end IP address, and a receiving end port number. The MME sends a bearer setup request to the gateway, and the gateway forwards the bearer request to the base station to which the requesting end belongs, and then the base station establishes a wireless. The bearer request is forwarded to the requesting end, and the requesting end responds to the establishing the radio bearer request, and the base station sends the bearer setup response information to the gateway, and the gateway forwards the bearer setup response information to the MME, and the bearer of the requesting end is established. Similarly, the gateway will be established. The bearer request is sent to the base station to which the receiving end belongs, and the base station sends a radio bearer request to the receiving end, and the receiving end responds to the establishing the radio bearer request, and the base station sends the bearer setup response information to the gateway, and the gateway forwards the bearer setup response information. To the MME, the bearer establishment of the receiving end is completed.

在 MME请求建立承载之前，还包括 MME预处理的步骤 5011， MME向核心网查询该承载上的业务是否支持本地交换，若承载上的业务能支持本地交换，则 MME在承载建立过程中获取请求端与接收端接的地址信息，该地址信息包括请求端的 IP地址和端口号，与接收端的 IP地址和端口号，这里获取的接收端的 IP地址和端口号可能有多个。步骤 502，基站判断是否执行本地交换； Before the MME requests to establish a bearer, the method further includes a step 5011 of the MME pre-processing, and the MME queries the core network whether the service on the bearer supports the local exchange. If the service on the bearer can support the local exchange, the MME obtains the request in the bearer establishment process. The address information of the terminal and the receiving end, the address information includes the IP address and port number of the requesting end, and the IP address and port number of the receiving end. There may be multiple IP addresses and port numbers of the receiving end obtained here. Step 502: The base station determines whether to perform local exchange.

MME将获取的请求端与接收端的地址信息发送给接收端所属的网关后，网关将接收到的该地址信息转发给请求端所属的基站，基站保存该地址信息，当基站再次收到网关发送的地址信息，包括终端 IP地址和端口号以及通信对端的 IP地址和端口号时，基站判断新收到的地址信息是否已经保存，如果已经保存，则说明通信双方终端接入同一个基站下，即支持本地交换，如果不支持本地交换，则按照现有技术通过核心网转发通信业务，具体流程不再赘述。 After the MME sends the obtained address information of the requesting end and the receiving end to the gateway to which the receiving end belongs, the gateway forwards the received address information to the base station to which the requesting end belongs, and the base station saves the address information, and the base station receives the gateway information again. When the address information includes the terminal IP address and port number and the IP address and port number of the communication peer, the base station determines whether the newly received address information has been saved. If it has been saved, the terminal of the communication terminal accesses the same base station, that is, The local exchange is supported. If the local exchange is not supported, the communication service is forwarded through the core network according to the existing technology. The specific process is not described here.

步骤 503，基站将判断得到的支持本地交换的通信双方终端绑定；具体指将请求端 IP地址及端口号与接收端 IP地址及端口号绑定，请求端承载 ID与接收端承载 ID绑定，其中绑定的承载 ID指终端和基站间的无线承载 ID。由于请求端的某一个承载上可能向多个接收端发起业务，因此请求端的一个承载 ID可能与多个接收端的承载 ID绑定。 Step 503: The base station binds the determined communication terminal that supports the local exchange; specifically, binding the IP address and port number of the requesting end to the IP address and port number of the receiving end, and binding the bearer ID of the requesting end to the bearer ID of the receiving end. The bearer ID of the binding refers to the radio bearer ID between the terminal and the base station. A bearer ID of a requesting end may be bound to a bearer ID of multiple receiving ends because a certain bearer on the requesting end may initiate a service to multiple receiving ends.

步骤 504，基站执行本地交换。 Step 504: The base station performs local exchange.

请求端通过请求端承载 ID将数据包发送给基站，基站识别到该数据包是来自绑定的承载 ID上的，于是基站将请求端承载 ID同绑定信息匹配，如果请求端承载 ID只与一个接收端承载 ID绑定，则基站直接在该接收端承载上向接收端转发该数据包；若请求端承载 ID与多个接收端承载 ID绑定，则基站解析收到的数据包，获得该数据包的目的 IP地址及端口号，通过获得地址信息中的目的 IP地址及端口号判断数据包的转发地址（即接收端承载 ID )并转发到对应的接收端。 The requesting end sends the data packet to the base station by using the bearer ID of the requesting end, and the base station recognizes that the data packet is from the bearer ID of the binding, and the base station matches the bearer ID of the requesting end with the binding information, if the requesting end carries the ID only A receiving end carries an ID binding, and the base station directly forwards the data packet to the receiving end on the receiving end bearer; if the requesting end bearer ID is bound to multiple receiving end bearer IDs, the base station parses the received data packet, and obtains The destination IP address and port number of the data packet are determined by obtaining the destination IP address and port number in the address information, and determining the forwarding address of the data packet (that is, the receiving end bearer ID) and forwarding it to the corresponding receiving end.

在上述实施例四中， MME 完成获取地址信息的工作并发送给基站，这样，基站只需要对收到的地址信息进行匹配就可以判断通信双方终端是否可以执行本地交换，减轻了基站的工作量； MME在同通信终端建立承载的过程中获取地址信息，而不是盲目的对所有上行数据包进行检测，提高了本地交换匹配的有效性。 In the fourth embodiment, the MME completes the work of obtaining the address information and sends the information to the base station. In this way, the base station only needs to match the received address information to determine whether the communication terminal can perform local exchange, thereby reducing the workload of the base station. The MME obtains the address information in the process of establishing the bearer with the communication terminal, instead of blindly detecting all the uplink data packets, thereby improving the effectiveness of the local exchange matching.

上述的实施例中，通过 MME获取通信双方终端的地址信息，也可以不通过 MME获取通信双方终端的地址信息，而是通过基站或网关本身识别并获取通信双方终端的地址信息，这时基站或网关具备识别 S1AP ( S1 Application Protocol ) 消息中非接入层消息的功能，下面举个基站获取通行双方终端地址信息并执行本地交换的实施例，包括： In the foregoing embodiment, the MME obtains the address information of the terminal of the communication terminal, and may acquire the address information of the terminal of the communication terminal without using the MME, but identify and acquire the address information of the terminal of the communication terminal by the base station or the gateway itself, at this time, the base station or The gateway has the function of identifying the non-access stratum message in the S1AP (S1 Application Protocol) message, and the following base station obtains the terminal address of both the transit terminals. Examples of information and performing local exchanges, including:

在网络侧发起的承载建立请求的非接入层消息中，加入通信双方终端的 In the non-access stratum message of the bearer setup request initiated by the network side, the terminal of the communication terminal is added.

IP地址及端口号； IP address and port number;

基站收到网络侧为请求端建立承载请求后，识别并获取该请求信息中的地址信息，该地址信息包含的请求端 IP地址、请求端端口号和接收端 IP地址、接收端端口号，基站将获取的该地址信息保存。同时基站将建立无线承载请求发给请求端，请求端响应该建立无线承载请求，基站将承载建立响应信息发送给 MME，请求端的承载建立完成；同样的，基站将建立无线承载请求发给接收端，接收端响应该建立无线承载请求，基站将承载建立响应信息发送给 MME, 接收端的 7 载建立完成。 After receiving the bearer request for the requesting end, the base station identifies and obtains the address information in the request information, where the address information includes the requesting end IP address, the requesting port number, the receiving end IP address, the receiving port number, and the base station. Save the obtained address information. At the same time, the base station sends a radio bearer request to the requesting end, and the requesting end responds to the establishment of the radio bearer request, and the base station sends the bearer setup response information to the MME, and the bearer of the requesting end is established. Similarly, the base station sends a radio bearer request to the receiving end. The receiving end responds to the establishment of the radio bearer request, and the base station sends the bearer setup response information to the MME, and the 7-carrier establishment of the receiving end is completed.

与接收端建立承载过程中，基站获取到接收端 IP地址、接收端端口号和请求端 IP地址、请求端端口号，基站判断所获取的地址信息是否已经保存，如果已经保存，则说明通信双方终端接入同一个基站，即支持本地交换。 During the establishment of the bearer with the receiving end, the base station obtains the IP address of the receiving end, the port number of the receiving end, the IP address of the requesting end, and the port number of the requesting end. The base station determines whether the obtained address information has been saved. If it has been saved, the two parties indicate that the communicating party The terminal accesses the same base station, that is, supports local exchange.

基站将判断得到的支持本地交换的通信双方终端绑定，具体指将请求端 IP地址及端口号与接收端 IP地址及端口号绑定，请求端承载 ID与接收端承载 ID绑定，其中绑定的承载 ID指终端和基站间的无线承载 ID。由于请求端的某一个承载上可能向多个接收端发起业务，因此请求端的一个承载 ID可能与多个接收端的承载 ID绑定。 The base station binds the terminal of the communication terminal that supports the local exchange, and specifically binds the IP address and port number of the requesting end to the IP address and port number of the receiving end, and binds the bearer ID of the requesting end to the bearer ID of the receiving end, where the binding is performed. The fixed bearer ID refers to the radio bearer ID between the terminal and the base station. A bearer ID of a requesting end may be bound to a bearer ID of multiple receiving ends because a certain bearer on the requesting end may initiate a service to multiple receiving ends.

基站执行本地交换。请求端通过请求端承载 ID将数据包发送给基站，基站识别到该数据包是来自绑定的承载 ID上的，于是基站将请求端承载 ID同绑定信息匹配，如果请求端承载 ID只与一个接收端承载 ID绑定，则基站直接在该接收端承载上向接收端转发该数据包；若请求端承载 ID与多个接收端承载 ID绑定，则基站解析收到的数据包，获得该数据包的目的 IP地址及端口号，通过获得的目的 IP地址及端口号判断数据包的转发地址（即接收端承载 ID )并转发到对应的接收端。 The base station performs local switching. The requesting end sends the data packet to the base station by using the bearer ID of the requesting end, and the base station recognizes that the data packet is from the bearer ID of the binding, and the base station matches the bearer ID of the requesting end with the binding information, if the requesting end carries the ID only A receiving end carries an ID binding, and the base station directly forwards the data packet to the receiving end on the receiving end bearer; if the requesting end bearer ID is bound to multiple receiving end bearer IDs, the base station parses the received data packet, and obtains The destination IP address and port number of the data packet, the destination IP address and the port number of the obtained packet are used to determine the forwarding address of the data packet (ie, the receiving end bearer ID) and forwarded to the corresponding receiving end.

网关获取通行双方终端地址信息并执行本地交换的具体实现方式同基站获取通行双方终端地址信息并执行本地交换的实施例相同，在基站或网关识别 S1AP消息中的非接入层消息从而获取地址信息的实施例中，基站或网关不需要对每个上行数据包盲目的进行检测，提高了本地交换匹配的有效性。 The specific implementation manner in which the gateway obtains the terminal address information of the two parties and performs local exchange is the same as the embodiment in which the base station obtains the terminal address information of the two parties and performs local exchange, and the base station or the gateway identifies the non-access stratum message in the S1AP message to obtain the address information. In an embodiment, the base station or the gateway does not need to detect each uplink data packet blindly, which improves the effectiveness of the local exchange matching.
