[0037] like Figure 2 As shown, the business process of a specific embodiment of the method of the present invention is as follows: Step 1: System initialization, starting the relevant service modules of the communication capability open platform. The specific process is as follows: (1) Start the cache middleware (redis); start the capability distribution gateway and connect to the cache middleware (redis); start the signaling distribution gateway and connect to the cache middleware (redis); (2) The signaling distribution gateway calls the capability distribution gateway SC configuration manifest query interface to initialize the SC configuration manifest. The capability distribution gateway SC configuration manifest response is described below: { "returnCode": "000000", "description": "success", "data": [{ "scId": "100001", "abiSet": [{ "id": "100", "priority": "0" }, { "id": "200", "priority": "5" } ] } ] } returnCode represents a response value, a value of 000000 indicates success, and other values indicate failure; description represents an error message; data represents SC configuration information; data.n.scId represents the SC attribute in the signaling header field, which is one-to-one corresponding to IFC, and the application ID is planned to be used as the SC value; data.n.abiSet represents the capability center set information; data.n.abiSet.n.id represents the capability center ID; data.n.abiSet.n.priority represents the capability center priority, and the smaller the priority is, the higher the priority is.

[0038] (3) The signaling distribution gateway receives the SC configuration list response and stores it in the gateway global memory; the signaling distribution gateway calls the capability distribution gateway capability center set list query interface to initialize the capability center set list.

[0039] (4) The signaling distribution gateway receives the capability center set list response and stores it in the gateway global memory. Start all the capability center services in the capability center set. The capability center services can dynamically increase or decrease the number of started services according to the actual load condition, so as to control the business processing capacity of the communication capability opening platform.

[0040] Step 2, user A subscribes to the communication capability opening platform. User A subscribes to the communication capability opening platform through the third-party management platform. The third-party management platform synchronizes data to the capability distribution gateway.

[0041] Step 3, the capability distribution gateway updates the SC configuration and capability center set data of the signaling distribution gateway.

[0042] (1) The capability distribution gateway calls the signaling distribution gateway SC configuration update interface, and the specific interface description is as follows: { "id": "sc-xxxxxxxx", "jsonrpc": "2.0", "method": "shv_set", "params": { "name":"100001", "type":"str", "value":"1-2" } } Wherein, the id represents a request serial number, in the format of identification header-8-bit random code, the signaling distribution receives a message and processes, and then performs feedback asynchronously through a UDP protocol, the ability distribution gateway judges whether it is successful or processing timeout according to the request serial number, and the message needs to be retransmitted if it is unsuccessful. The Jsonrpc represents a JSON-RPC protocol version number, fixed 2.0; the method is fixed as shv_set; the params.name represents an SC value; the params.type represents a type of value parameter, and the fixed value is str; and the params.value represents IDs of all ability center sets, separated by a dash. For example, if 3 ability center sets are hung down, the ability center sets are in a priority order, and the IDs are 1, 5 and 3 respectively, then the value field is 1-5-3.

[0043] (2) The signaling distribution gateway receives SC configuration update information, and updates to a gateway global memory, the ability distribution gateway calls an ability center set update interface of the signaling distribution gateway, and the interface is specifically explained as follows: { "id": "abi-xxxxxxxx", "jsonrpc": "2.0", "method": "abilities_set", "params": { "setid": "1", "addr": ["sip:IP:PORT", "sip:IP:PORT", ……] } } Wherein, id represents request serial number. Format represents identification header-8-bit random code. The signaling distribution receives the message and processes, and then performs feedback asynchronously through the UDP protocol. The ability distribution gateway judges whether it is successful or processing timeout according to the request serial number, and the message needs to be retransmitted if it is unsuccessful. Jsonrpc represents the JSON-RPC protocol version number, which is fixed as 2.0. Method represents fixed as abilities_set. Params.setid represents the ability center cluster ID. Params.type represents the ability center cluster address list, and the single data format is sip: IP: PORT, such as ["sip: 192.168.21.123: 5080", "sip: 192.168.21.312: 5080"].

[0044] (3) The signaling distribution gateway receives the ability center cluster information and updates it to the gateway global memory.

[0045] Step 4, user A calls user B and triggers the call to the communication capability opening platform. The specific process is as follows: (1) User A dials user B, and the IMS detects that user A subscribes to the communication capability opening platform service. The IMS adds the sc=100001 field to the route header domain of the call signaling and sends it to the signaling distribution gateway. (2) The signaling distribution gateway receives the call signaling, parses the sc field in the route header domain to obtain the value 100001, and queries the corresponding ability center cluster configuration information of the SC in the global memory. The signaling distribution gateway generates a unique identifier X-Call-Id for this call and saves it to the cache server.

[0046] (3) The signaling distribution gateway queries the ability center cluster address list of the ability center cluster with ID 100 in the global memory. The signaling distribution gateway adds X-Call-Id, the current ability center cluster (ID=100), and SC identifier to the call signaling. The signaling distribution gateway sends the call to the ability center with the lowest load (ID=100).

[0047] (4) The ability center (ID=100) receives the call signaling, queries the service information from the ability distribution gateway according to the SC, returns the service query response, and processes the service response. The signaling distribution gateway queries the ability center cluster information of the current call from the cache server according to the X-Call-Id in the signaling returned by the ability center.

[0048] (5) The signaling distribution gateway sets the current triggered capability center set ID (100) as triggered, and acquires the next to be triggered capability center set (ID=200); (6) The signaling distribution gateway inquires the capability center set address list of the capability center set ID=200 in the global memory; the signaling distribution gateway adds X-Call-Id, the current capability center set (ID=200) and SC identification to the call signaling. The signaling distribution gateway sends the call to the capability center (ID=200) with the lowest load.

[0049] (7) The capability center (ID=200) receives the call signaling, inquires the service information from the capability distribution gateway according to the SC; the capability distribution gateway returns the service inquiry response; the capability center (ID=200) processes the service response and sends the call back to the signaling distribution gateway. The signaling distribution gateway inquires the current capability center set information of the call from the cache server according to X-Call-Id in the signaling sent back by the capability center.

[0050] (8) The signaling distribution gateway finds that the current call corresponding capability center set has been triggered completely. The signaling distribution gateway deletes all private signaling information used for internal communication and sends the call signaling to the IMS.

[0051] (9) The IMS receives the call signaling and sends it to user B; user B answers the phone; user A and user B talk; user A and user B end the call; the IMS sends the call end signaling to the signaling distribution gateway; (10) The signaling distribution gateway sends the call end signaling to the capability center corresponding to the current call in turn. The capability center (ID=100, ID=200) pushes the service result of the current call to the capability distribution gateway. The signaling distribution gateway clears the cache information related to the current call on the cache server.
