However, for GSM / CDMA dual-mode terminal users, CDMA users may roam to the GSM network, and GSM users may also roam to the CDMA network, so the ISDN (Integrated ServicesDigital Network, Integrated ServicesDigital Network) number of the destination user has been If the network where the user is currently located cannot be determined, it is usually necessary to determine the network to which the user currently belongs by querying the address attribute of the MSC (Mobile switching center) registered by the target user. In this case, the current CG signaling interworking The gateway cannot determine whether to convert the signaling according to the configured relationship between the destination user terminal number segment and the network

application example 1
[0055] Application example 1, when a CDMA user roams to a GSM network, such as Figure 5 As shown, the specific implementation steps of this application example are as follows:
[0056] Step 101, the short message service center (SC) judges that the ISDN number segment of the destination terminal user belongs to the CDMA network, and uses the CDMA signaling protocol to issue a call termination request message (MtToMscReq) to the CG signaling interworking gateway;
[0057] Step 102, the CG signaling interworking gateway sends a routing request message (SMS_REQUEST (REQ)) of the CDMA protocol to the CG integrated HLR to query routing information;
[0058] Step 103, the CG integrated HLR returns a routing request response message (sms_request(ACK)) to the CG signaling interworking gateway;
[0059] Wherein, after the CG integrated HLR receives the routing request query command, if the query finds that the terminal user is roaming (crossing from one network to another network), t...
application example 2
[0068] Application example 2, when a GSM user roams to a CDMA network, such as Figure 6 As shown, the concrete implementation steps of this method are as follows:
[0069] Step 201, the SC judges that the ISDN number segment of the destination terminal user belongs to the GSM network, and uses the GSM signaling protocol to issue a call termination request message (MT_Data_Req) to the CG signaling interworking gateway;
[0070] Step 202, the CG signaling interworking gateway sends a routing request message (Send_Route_Info_For_SM_Req) of the GSM protocol to the CG integrated HLR to query routing information;
[0071] Step 203, the CG integrated HLR sends a route request response message (Send_Route_Info_For_SM_Ack) to the CG signaling interworking gateway;
[0072] Wherein, after the CG integrated HLR receives the routing request query command, if the query finds that the terminal user is roaming, it will carry a special MSC number in the returned routing request response...

Abstract
The present invention is to provide a method and an apparatus for message handling. The method comprises: after receiving a termination message issued by a short message service center according to a signaling protocol of a home network of a destination user terminal number, issuing a routing request message to a home location register; and after receiving a routing request response message returned by the home location register, notifying the short message service center to alter the network signaling protocol for re-termination, if it is determined that the routing request response message carries a message identifying the destination user is not in the home network of the destination user terminal number. According to the present invention, automatic switch of signaling protocols for a message can be achieved based on the actual scene in the case of multi-network coexistence.
Description
technical field [0001] The present invention relates to CDMA (Code Division Multiple Access, Code Division Multiple Access) and GSM (Global System of Mobile communication, Global System for Mobile Communications) short message communication field, in No. 7 signaling network, realize the service of short message transmission, forwarding, In particular, it relates to a message processing method and device. Background technique [0002] CDMA and GSM are currently the most widely used communication networks. Both networks have a huge number of users. The intercommunication of short messages between CG (CDMA and GSM) networks is usually through the CG signaling interworking gateway (ie short message interworking gateway mobile Service Exchange Center, InterWorking Gateway MSC) realizes the conversion. Existing CG signaling interworking gateways are usually deployed at the network border. According to the configuration information of the home network of the target user terminal n...
