Problems solved by technology

[0065] The present invention provides a method, network and device for processing a late forwarding service, which is used to solve the problem that after the late forwarding service occurs, if the VCC service control entity does not need to be kept in the session path, it cannot be released from the session path. Or if the VCC service control entity needs to remain in the session path, it will not be able to obtain service notifications, resulting in the failure to update the user's call status

example 1

[0169] Method Example 1: The VCC service control entity is co-established with the GMSC (the GMSC is the incoming GMSC in the IMS domain) to complete the processing of the late forwarding service. see Figure 14 shown, including the following specific steps:

[0170] 1. The call has been routed to the IMS domain, and the CSCF triggers the call to the VCC service control entity through service triggering.

[0171] 2. When the VCC service control entity decides to connect the user in the CS domain, it will send an SRI message as the GMSC to the HLR to query the location of the user. The SRI message carries a routing optimization indication indicating that the late forwarding needs to be initiated by the GMSC, and at the same time carries the GMSC's Address (that is, the address of the VCC service control entity) and call reference number.

[0172] 3. The HLR sends a PRN to the VMSC where the user resides to request a roaming number, and the PRN message contains a routing optim...

example 2

[0183] Method Example 2: The VCC service control entity and the GMSC are set separately (here the GMSC is the incoming GMSC of the IMS domain), and intelligent triggering is adopted to complete the processing of the late forwarding service. see Figure 15 shown, including the following specific steps:

[0184] 1. GMSC1 receives the call connection signaling.

[0185] 2. The GMSC1 applies for user data from the HLR.

[0186] 3. The HLR downloads the called smart trigger to the GMSC1.

[0187] 4. GMSC1 triggers to the VCC service control entity (routing redirection entity) according to the trigger, and the call reference number 1 of this call and the address of GMSC1 are carried in the message.

[0188] 5. The VCC service control entity (routing redirection entity) records the call reference number 1 and the address of GMSC1, and returns an IMRN (IMS Routing Number) to GMSC1 to instruct GMSC1 to route the call to the IMS domain.

[0189] 6. GMSC1 routes the call to the IMS d...

[0207] Method Example 3: The VCC service control entity and the GMSC are set separately (here the GMSC is the incoming GMSC of the IMS domain), and the processing of the late forwarding service is completed by intercepting signaling. see Figure 16 shown, including the following specific steps:

[0208] 1. The call arrives from the CS domain to the GMSC1 of the home network to which the called party belongs.

[0209] 2. The GMSC1 sends an SRI message to the HLR to obtain the user location information, and the message contains the SOR operation supported by the GMSC1 and the call reference number 1 and the address of the GMSC1.

[0210] 3. The VCC signaling interception entity intercepts the SRI message and processes it. When the decision needs to pass the call through the IMS domain, the route redirection entity of the VCC service control entity (set together with the signaling interception entity) saves the call reference number 1 and address of GMSC1, and then returns the ...

Abstract

The method is used for solving the issue that is if the VCC service control entity has no need to be reserved in session path, it can't be released from the session path after a later forwarding server occurs. The method comprises: a) after VCC service control entity gets the information of later forwarding server, when said VCC service control entity makes interaction with the visited place to the a roaming number, said later forwarding information is informed to the visited place; b) when originating a later forwarding service, according to said later forwarding information, the visited place indicates the incoming GMSC to optimize the route; c) said incoming GMSC executes the later forwarding service optimizing operation.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, network and device for processing late forwarding services. Background technique [0002] During the evolution of the wireless network from the 2G network to the 3G network, the 3G network and the 2G network will coexist for a long period of time. topic. [0003] The network needs to be aware of the user's registration status on the two networks, so that when a call needs to be connected to the user, it can select the appropriate network for connection. The network also needs to anchor all of the user's calls so that the user can exercise secondary control when switching between the two networks. [0004] In order to solve the above problems, both 3GPP and 3GPP2 standards organizations have proposed an entity based on the IMS domain, which can perform anchor control, respectively detect the user's registration and session status in the two networks, and perform user ...
