Problems solved by technology

[0005] In order to solve the problem of message service intercommunication between the IMS domain and the CS domain and the implementation of the message service under the condition of a shared number, the purpose of the present invention is to provide a method for the message intercommunication between the IMS domain and the CS domain, through the HSS in the IMS domain and the HLR in the CS domain Interaction, completing the query of user registration network and corresponding routing information between the two networks, realizing the intercommunication of message services and the message service under the condition of sharing numbers

Embodiment 1

[0046] Referring to Figure 1, the message service flow steps from the IMS domain to the CS domain are as follows:

[0047] Step 1a: The P-CSCF receives the SIP message sent by the first UE in the IMS domain, and forwards the SIP message to the S-CSCF,

[0048] P-CSCF is the first connection point from the access network to IMS, and is the proxy server in SIP, which is responsible for accepting requests or responses and forwarding them.

[0049]S-CSCF performs session control services, including registering and maintaining session status, and acts as a SIP server;

[0050] Step 1b: S-CSCF triggers to message server according to iFC,

[0051] iFC is the description of the user contract downloaded from the HSS when the user registers,

[0052] The message server can judge whether it is sent to the mobile terminal according to the receiving address of the message, and supports text messages, multimedia messages, file transfers, short messages, etc.;

[0053] Step 1c: The messag...

Embodiment 2

[0070] The difference from Embodiment 1 lies in step 1h. In this embodiment, the S-CSCF does not have the routing function directly to the message gateway, so the S-CSCF first returns the subscription information of the second UE to the message server, and the message server then Send the SIP message to the corresponding message gateway.

Embodiment 3

[0072] Referring to Figure 2, the message service flow steps from the CS domain to the IMS domain are as follows:

[0073] Step 3a: The MSC / VLR receives the SMPP message sent by the second UE in the CS domain, and forwards it to the SMSC;

[0074] Step 3b: The SMSC queries the HLR for the subscription information of the receiving party's first UE;

[0075] Step 3c: The HLR finds that the first UE is not a CS domain user, and queries the HSS of the IMS domain for the subscription information of the first UE;

[0076] Step 3d: The HSS returns the subscription information of the first UE to the HLR;

[0077] Step 3e: the HLR returns the subscription information of the first UE to the SMSC;

[0078] Step 3f: The SMSC sends the SMPP message to the corresponding message gateway according to the subscription information;

[0079] Step 3g: The message gateway performs protocol conversion, converts the SMPP message into a SIP message, and forwards the SIP message to the message serv...

Abstract

This invention relates to one method between IMS area bad CS area, which realizes IMS HSS and CS interacting and two networks information connecting and common codes information business and comprises the following steps: IMS area receives first UE SIP message and transferring SIP message to S-CSCF and then sending the contract message to relative message gate for agreement conversion; converting SIP message into SMPP through CS area to second UE.

Description

technical field [0001] The present invention relates to a method for message intercommunication, in particular to a method for communicating information through home subscriber server (Home Subscriber Server, hereinafter referred to as HSS) and circuit switching (Circuit-Switch, hereinafter referred to as A method for implementing message intercommunication between two networks through interaction of a Home Location Register (HLR) in a CS domain belongs to the technical field of communication. Background technique [0002] Under the existing network environment, the short message service has brought rich profits to operators with its high penetration rate and rich business methods. The current short message service realizes the storage and forwarding of short messages through the dedicated short message platform Short Message Service Center (Short Message Service Center, hereinafter referred to as SMSC), and realizes the sending and receiving of messages between different po...
