Detailed ways

Fig. 1 is a flowchart of an embodiment of the data direct processing method of the present invention. As shown in Fig. 1, the method includes:

Step 100, the gateway between the first communication system and the second communication system receives the source user terminal request from the source base station to which the source user terminal belongs in the first communication system, and the target user terminal in the second communication system A service request message for a user terminal to communicate and interact, wherein the service request message includes: a source base station identifier and a target user terminal identifier;

The first communication system and the second communication system involved in the embodiment of the present invention are two different communication systems, and the first communication system and the second communication system are connected through a gateway. When the source user terminal in the first communication system wants to perform service interaction with the target user terminal in the second communication system, the source user terminal first sends a service request message including the target user terminal identifier to the source base station to which it belongs, and the source base station passes The gateway of the core network of the first communication system sends a service request message to the gateway between the first communication system and the second communication system, the service request message includes: the source base station identifier and the target user terminal identifier, so that the first communication system and the second communication system The gateway between the second communication systems receives a service request message from the source base station to which the source user terminal belongs in the first communication system, in which the source user terminal requests communication interaction with the target user terminal in the second communication system.

Step 101, the gateway determines whether the source base station and the target base station to which the target user terminal belongs have the ability to provide direct data for the communication interaction, and if so, instructs the source base station and the target base station to adopt The inter-base station interface establishes a data direct channel, so that the source user terminal and the target user terminal use the data direct channel to perform the communication interaction.

The gateway parses the service request message sent by the source base station to obtain the source base station identifier and the target user terminal identifier, and then determines whether the source base station and the target base station to which the target user terminal belongs have the ability to provide data direct connection for communication interaction. It should be noted that the determination of whether the source base station and the target base station to which the target user terminal belongs has the capability of providing data direct connection for communication interaction is based on factors such as the communication distance between base stations meeting the direct connection requirements. Among them, the data direct communication capability between the source base station and the target base station specifically includes: first, both the source base station and the target base station have inter-base station equipment interfaces for direct data transmission between base station equipment; second, the base station of the source base station Both the interface between devices and the user plane protocol stack of the interface between base station devices of the target base station support the processing of data direct services, where Figure 2 shows the user plane protocol stack for service data interaction between the source base station and the target base station through the interface between base station devices. As shown in Figure 2, the user plane protocol stack of the interface between base station equipment mainly includes: physical layer, data link layer, IP layer, User Datagram Protocol (User Datagram Protocol; UDP for short) layer, general data transmission layer and Business data layer. Therefore, if the gateway between the first communication system and the second communication system determines that both the source base station in the first communication system and the target base station in the second communication system have the capability of providing direct The source base station and the target base station send an indication message, instructing the source base station and the target base station to establish a direct data channel by using an interface between base station devices. When the gateway determines that a data direct channel has been established between the source base station and the target base station, it instructs the source base station to use the data direct channel to transmit to the target base station the service data uploaded by the source user terminal and to be sent to the target user terminal, and then the target The base station sends the service data to the target user terminal, so that the service data transmission path between the source user terminal and the target user terminal no longer passes through the core network of the first communication system and the second communication system, but only passes through the connection between the base station in the access network. The direct route between them can be completed.

In the data direct processing method provided in this embodiment, the gateway between the first communication system and the second communication system receives the request from the source user terminal sent by the source base station to which the source user terminal belongs in the first communication system and communicates with the second communication system. After the target user terminal in the communication interaction service request message, when it is determined that the source base station and the target base station have the ability to provide direct data for the communication interaction, the source base station and the target base station are instructed to use the interface between base station equipment to establish Data pass-through channel, so that the source user terminal and the target user terminal use the data pass-through channel to communicate and interact, thereby saving data processing time, greatly reducing communication delay, and reducing the transmission line of the core network, central node equipment and backbone network burden.

Fig. 3 is a flow chart of another embodiment of the data direct processing method of the present invention. As shown in Fig. 3, the method includes:

Step 200, the gateway between the first communication system and the second communication system receives the source user terminal request from the source base station to which the source user terminal belongs in the first communication system and the target user terminal in the second communication system A service request message for a user terminal to communicate and interact, wherein the service request message includes: a source base station identifier, a target user terminal identifier, service type information, and service requirement information corresponding to the service type information;

When the source user terminal in the first communication system wants to perform service interaction with the target user terminal in the second communication system, the source base station analyzes the service request message sent by the source user terminal to obtain the target user terminal identifier, service type information, The service requirement information corresponding to the service type information, and then determine whether the target user terminal belongs to itself, and the source base station sends the service to the gateway between the first communication system and the second communication system through the gateway of the core network of the first communication system A request message, the service request message includes: source base station identifier, target user terminal identifier, service type information, and service requirement information corresponding to the service type information, so that the gateway between the first communication system and the second communication system receives the first communication A service request message sent by the source base station to which the source user terminal belongs in the system, in which the source user terminal requests communication interaction with the target user terminal in the second communication system.

Step 201, the gateway determines whether the communication interaction can be completed by using the data direct channel according to the service requirement information corresponding to the service type information, if not, execute step 202, and if yes, execute step 203;

The gateway between the first communication system and the second communication system parses the service request message sent by the source base station and obtains the source base station identifier, target user terminal identifier, service type information, and service requirement information corresponding to the service type information, the gateway First, according to the business requirement information corresponding to the business type information, it is determined whether the business requirement can use the data direct channel to complete the communication interaction. It should be noted that the business requirement information includes the transmission traffic and transmission speed corresponding to the business type information. In some In the application scenario, the direct data transmission channel between the source base station and the target base station can meet the limited business requirements. Therefore, the gateway needs to judge whether the data direct channel between the base stations can be used to complete the communication interaction according to the business demand information. If yes, go to step 203, otherwise go to step 202.

Step 202, the gateway completes the communication interaction between the source base station and the target base station through the core network equipment.

If the gateway between the first communication system and the second communication system determines that the communication interaction between the source user terminal and the target user terminal cannot be completed using the data direct channel according to the service requirement information corresponding to the service type information, the gateway indicates The source base station uses the traditional data transmission mode to communicate with the target base station, that is, the source base station transmits the service data requested for transmission to the core network equipment of the first communication system through the central control node and the backbone network line, and the first communication system The core network equipment of the system transmits the service data to the gateway between the first communication system and the second communication system, and transmits the service data to the core network equipment of the second communication system supported by the target user terminal through the gateway, so that the The core network equipment of the second communication system transmits the service data to the target base station, and the target base station transmits the service data to the target user.

Step 203, the gateway sends a target base station query message including the target user terminal identifier to the core network device in the second communication system that stores terminal location information, and receives a query message including the target base station identifier returned by the core network device response message;

If the gateway between the first communication system and the second communication system determines that the communication interaction between the source user terminal and the target user terminal can be completed through a data direct channel according to the service requirement information corresponding to the service type information, then the gateway needs to determine the target The target base station to which the user terminal belongs, therefore, the gateway sends a target base station query message including the target user terminal identifier to the core network device storing terminal location information in the second communication system, and receives the target base station identifier returned by the core network device The response message, so that the gateway obtains the identity of the target base station according to the response message.

Step 204, the gateway queries the locally stored base station direct routing information represented by the base station identifier according to the source base station identifier and the target base station identifier, so as to determine whether there is a connection between the source base station and the target base station. If the above-mentioned communication interaction provides the capability of data pass-through, if so, perform step 205, otherwise, perform step 202;

The gateway queries locally deployed direct routing information. The direct routing information includes: the base station direct topology represented by the base station identifier, where the base station identifier can be the ID assigned to each base station by the system or the IP address of the base station. The gateway first determines whether there is a direct route corresponding to the source base station identifier and the target base station identifier according to the base station direct topology structure represented by the base station identifier. If there is no direct route, it determines that there is no communication interaction between the source base station and the target base station. If the capability of data pass-through is provided, step 202 is performed. If the pass-through route exists, it is determined that the source base station and the target base station have the capability of providing data pass-through for communication interaction, and step 205 is performed;

Step 205, the gateway instructs the source base station and the target base station to establish a direct data channel through an inter-base station interface, so that the source user terminal and the target user terminal perform the communication interaction through the data direct channel.

If the gateway determines that there is a direct data route between the source base station and the target base station for the service data of the communication interaction, the gateway sends an indication message to the source base station and the target base station, instructing the source base station and the target base station to establish a data direct channel through the interface between base station equipment . When the gateway determines that a data direct channel has been established between the source base station and the target base station, it instructs the source base station to use the data direct channel to transmit to the target base station the service data uploaded by the source user terminal and to be sent to the target user terminal, and then the target base station The service data is sent to the target user terminal, so that the service data transmission process between the source user terminal and the target user terminal does not pass through the core network, but can be completed only through the base station direct route in the access network.

In the data direct processing method provided in this embodiment, the gateway between the first communication system and the second communication system receives the request from the source user terminal sent by the source base station to which the source user terminal belongs in the first communication system and communicates with the second communication system. After the target user terminal in the communication interaction service request message, when it is determined that the source base station and the target base station have the ability to provide direct data for the communication interaction, the source base station and the target base station are instructed to use the interface between base station equipment to establish Data pass-through channel, so that the source user terminal and the target user terminal use the data pass-through channel to communicate and interact, thereby saving data processing time, greatly reducing communication delay, and reducing the transmission line of the core network, central node equipment and backbone network burden, and further improve the reliability of data transmission.

Fig. 4 is a flowchart of another embodiment of the data direct processing method of the present invention. As shown in Fig. 4, the method includes:

Step 300, the source base station to which the source user terminal belongs in the first communication system sends the source user terminal request and the target user terminal in the second communication system to the gateway between the first communication system and the second communication system A service request message for communication interaction, where the service request message includes: a source base station identifier and a target user terminal identifier;

Step 301, the source base station receives the indication message including the identity of the target base station sent by the gateway after determining that the source base station and the target base station to which the target user terminal belongs has the capability of providing direct data for the communication interaction , and establish a direct data channel between the base station equipment interface and the target base station according to the indication message;
