Problems solved by technology

[0011] After the telecommunication network evolves to the IMS network architecture, there will still be a large number of service demands of traditional ISDN terminal users, but at present, it is not possible to maintain call continuity (remain Business scenarios in call on invocation) mode

Embodiment 1

[0046] The embodiment of the present invention provides a method for implementing call diversion, such as figure 1 As shown, the method includes:

[0047] Step 101: receive the REFER message that multi-service access point (Multi-Service Access Node, MSAN) sends, and this REFER message is formed by the FACILITY message that multi-service access point will receive by the service party (ServedUser) and sends, and this The REFER message includes the number of the served party, the transfer target party (TransferTarget User) number, call diversion service indication information and call continuation information;

[0048] Step 102: judging whether the served party has call diversion service authority;

[0049] Step 103: If yes, trigger the call diversion business logic, and initiate a call to the transfer destination;

[0050] Step 104: Release the call from the transferred party to the served party when receiving the response from the transfer destination party.

[0051] Furthe...

Embodiment 2

[0055] The embodiment of the present invention provides a method for implementing call diversion, such as figure 2 As shown, the method includes:

[0056] In step 201, the transferred party (Transfee User) sends an INVITE message to the AS to initiate a call.

[0057] In step 202, the AS sends the INVITE message to the MSAN.

[0058] In step 203, the MSAN converts the INVITE message into a call establishment request message, and sends the call establishment request message to the served party (Server User).

[0059] Step 204, the served party receives the call progress message, executes the CD operation, and sends the call progress message to the MSAN.

[0060] In step 205, the MSAN receives the call setup confirmation message, converts the call progress message into a 183 response signaling, and sends the 183 response signaling to the AS.

[0061] In step 206, the AS sends a 183 response signaling to the transferred party.

[0062] The steps described in steps 201-206 ar...

Embodiment 3

[0097] The embodiment of the present invention provides an integrated service access point, such as image 3 shown, including:

[0098] The receiving module is used to receive the FACILITY message sent by the service party;

[0099] A mapping module, configured to map the FACILITY message into a REFER message, where the REFER message includes a served party number, a transfer destination party number and call continuation information;

[0100] A sending module, configured to send the REFER message to the application server.

[0101] The embodiment of the present invention provides an application server, such as Figure 4 shown, including:

[0102] The receiving module is used to receive the REFER message sent by the integrated service access point MSAN. The REFER message is formed by mapping the FACILITY message received by the integrated service access point from the service party. The REFER message includes the number of the service party, Transfer destination number and...

Abstract

The embodiment of the invention discloses a method, a device and a system for realizing a call forwarding service, which belong to the field of communication. The method comprises the following steps: receiving an REFER message sent by a multi-service access node (MSAN), wherein the REFER message is formed by mapping a received FACILITY message sent by a served party by the multi-service access node and comprises a number of the served party, the number of a forwarding target, call forwarding service indicating information and call duration information; judging whether the served party has the authority of the call forwarding service; if the served party has the authority of the call forwarding service, triggering the logic of the call forwarding service and initiating a call to the forwarding target; and when receiving a response to the forwarding target, releasing the call from a forwarded party to the served party. The method, the device, and the system of the embodiment of the invention realize a scene of the call forwarding service in a remain call on invocation mode on the basis of a conventional ISDN terminal under IMS architecture.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for realizing call diversion service. Background technique [0002] IP Multimedia Subsystem (IP Multimedia Subsystem, IMS) is a subsystem that provides IP-based multimedia session control in the next generation network, including all core network elements that provide multimedia service control such as audio, video, text, and instant messaging. The Session Initiation Protocol (SIP) protocol is used as an IMS control layer protocol to carry call control signaling and provide unified multimedia services and applications. In the field of fixed network, Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN) is developing the network architecture of Next Generation Network (NGN), IMS and public switching telephone switching network (Public Switched Telephone Network, PSTN) / Integrated Services Digital Network (Int...
