[0086] Fig. 11 shows a flow chart of application server assignment when a user needs a third-party registration according to an embodiment of the present invention. As shown in Figure 11, when the user needs a third-party registration, the application server allocation includes the following steps:

[0087] In step S1102, a normal IMS network UE registration process is performed.

[0088] Step S1104, after the user registration is successful, the S-CSCF performs business logic control according to the initial filtering rules downloaded from the HSS and finds that third-party registration is required.

[0089] In step S1106, the initial filtering rule matched with the third-party registration records the SIP URLs of several application servers, and the S-CSCF selects an application server in the application server address list according to the configured policies or rules thereon. Among them, these policies and rules can be formulated by the operator, or they can be the person...

[0093] FIG. 12 shows a flow chart of implementing application server allocation for user origination services according to an embodiment of the present invention. As shown in Figure 12, the following steps are included:

[0094] In step S1202, the user sends an initial call request and sends a SIP Invite message to the P-CSCF to which it is connected.

[0095] In step S1204, the P-CSCF routes the SIP Invite message received from the user to the S-CSCF selected when the user registered. If the user is not registered but the user has signed an unregistered service, the existing The network selects an S-CSCF for the user to process the user's service request.

[0096] Step S1206, after receiving the SIP Invite message, the S-CSCF performs service logic control according to the initial filtering rules in the user subscription information saved therein, and searches for the initial filtering rules matching this service request.

[0102] Fig. 13 shows the process of implementing application server allocation for user termination service according to an embodiment of the present invention. As shown in Figure 13, the process of implementing application server allocation for the user terminal call service includes the following steps:

[0103] In step S1302, the opposite end initiates a service request to the user, and the SIP Invite message is routed to the S-CSCF providing the service for the user.

[0104]Step S1304, after the S-CSCF receives the SIP Invite message, it can know that the service request is an origination request according to the content of the header field of the message, and do it according to the initial filter rule in the user subscription information stored on it. Business logic control, looking for the initial filtering rules that match this business request.

[0105] Step S1306, when the S-CSCF finds a matching initial filtering rule, it finds several application server SIPURLs st...

Abstract

The present invention provides a distribution method and a device of an application server. The method comprises: a S902, a call session control function entity selects an application server from one or more than one application server(s) recorded in the initial filtering rules in the user contract information to serve the user; a S904, the call session control function entity transmits the service request message to the selected application server; a S906, the selected application server serves for the user after receiving the service request message. The device comprises a receiver module used for receiving the service request message; a selecting module used to select an application server from one or more than one application server(s) recorded in the initial filtering rules in the user contract information to serve the user; and a message transmission module used to transmit the service request message to the selected application server. By using the method and the device of the present invention, the distribution workload of network management is reduced, and the system efficiency is improved.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to an application server allocation method and an application server allocation device. Background technique [0002] IP Multimedia Subsystem (IP Multimedia Subsystem, referred to as IMS) is a subsystem superimposed on the existing packet switching domain in the WCDMA network added in the R5 stage of 3GPP (third-generation mobile communication standardization partner project). Domain is the bearer channel for upper-layer control signaling and media transmission. Session Initiation Protocol (SIP) is introduced as a service control protocol. Using the characteristics of SIP's simplicity, easy expansion, and convenient media combination, the service control and bearer Separation of control to provide rich multimedia services; the main functional entities in IMS include Call Session Control Function (Call Session Control Function, CSCF for short) that controls functions such a...
