Be described below in conjunction with the IP terminal of the roaming state/non-roaming state that is in of accompanying drawing 1, accompanying drawing 2,3 pairs of WiMAX networks of accompanying drawing and the detailed process that the mobile network realizes short message service interworking.
Three processes that mainly comprise short message service interworking in Fig. 3 flow process, promptly the short message of the process that the IP terminal connects by BS, ASNGW and short message interconnecting gateway and IP terminal and short message interconnecting gateway are registered in the mobile network, the IP terminal beginning is exhaled the SMS terminal call process of process, IP terminal.
Fig. 3 connect and registration process in, the IP terminal in step 1-1, WiMAX network inserts the WiMAX network with authentication mode, the IP terminal obtains its IP address by DHCP (DHCP).
The authentication mode of IP terminal access WiMAX network can be EAP-SIM (Extension Authentication Protocol Subscriber Identity Module) authentication, EAP-UIM (Extension Authentication Protocol User Identity Module) authentication, EAP-AKA (Extension Authentication Protocol Authentication and key agreement) authentication etc. in this step.
From ASNGW, obtain the address that it presets the short message interconnecting gateway to step 1-2, IP terminal constructions domain name and according to the domain name of structure by domain name inquiry system.
The IP terminal can be according to NAI (addressness qualitative character language) form structure domain name in this step, as constructing domain name according to mobile network's identification information of IP terminal such as MSISDN/IMSI etc. with the network information of its IP access network, concrete form can be MSISDN/IMSI@Realm.If the IMSI of IP terminal is 8613912345678, and the IP terminal is in the WiMAX network, then the domain name of IP terminal constructions can for:
8613912345678@wimax.cmcc
The address information that presets short message interconnecting gateway Provisioning SM-IW to step 1-3, IP terminal according to its that obtains sends the request message that connects to Provisioning SM-IW.
Be to guarantee the fail safe of transmission of messages, the connected mode that can adopt that is connected of IP terminal and short message interconnecting gateway based on the tunnel.At this moment, the IP terminal should be Tunnel_Establish_Request (setting up tunnel connection request message) to the request message that connects that Provisioning SM-IW sends.
To step 1-4, Provisioning SM-IW receive set up tunnel connection request message after, AS in the WiMAX network (certificate server) sends Access-Request (inserting request) message, whether has authorized short message service and whether provides the service of short message service for this IP terminal by it to determine this IP terminal.
, need judge whether this IP terminal has opened short message service and whether Provisioning SM-IW is the short message interconnecting gateway of this IP terminal current service when the Access-Request message that the link block that receives Provisioning SM-IW is sent to step 1-5, AS.Because AS has set up the contextual information of this IP terminal in the verification process of IP terminal accessing IP network, so AS can realize above-mentioned deterministic process.
If AS determines this IP terminal and does not open short message service, then respond Access-Reject (admission reject) message to the link block of Provisioning SM-IW, and can in the Reply-Message of this message attribute, be with corresponding cause value, as do not open short message service etc.
If AS determines this IP terminal and has opened short message service, judge again then whether Provisioning SM-IW is the short message interconnecting gateway of this IP terminal current service, if Provisioning SM-IW is the short message interconnecting gateway of this IP terminal current service, then AS directly responds Access-Accept (allowing to insert) message to Provisioning SM-IW, if Provisioning SM-IW is not the short message interconnecting gateway of this IP terminal current service, AS responds Access-Reject message to Provisioning SM-IW, and carries the IP address of short message interconnecting gateway Serving (current service) SM-IW on the current roaming ground of this IP terminal correspondence in Access-Reject message.
Receive the Access-Reject message of the IP address information that carries Serving SM-IW that AS sends to step 1-6, Provisioning SM-IW after, determine can't help that it provides the short message service service for this IP terminal, respond Tunnel_Establish_Response (failure response is set up in the tunnel) message to the IP terminal, and in Tunnel_Establish_Request message, carry the IP address information of the Serving SM-IW of AS distribution.
After receiving Tunnel_Establish_Request message to step 1-7, IP terminal,, send Tunnel_Establish_Request message to Serving SM-IW according to the IP address information of the Serving SM-IW that carries in the message.After Serving SM-IW receives Tunnel_Establish_Request message, repeat the process of above-mentioned steps 1-4 and step 1-5, receive the Access-Accept message that AS responds up to Serving SM-IW.
After Serving SM-IW receives Access-Accept message, set up and being connected of IP terminal by BS, ASN GW, this connection can connect for tunnel as shown in Figure 2, and send to the IP terminal and to carry the Tunnel_Establish_Response message that successful information is set up in the tunnel, and to step 1-8.
At step 1-8, successfully setting up the tunnel in the IP terminal with Serving SM-IW is connected, the IP terminal receives and carries after the tunnel sets up the Tunnel_Establish_Response message of successful information, the IP terminal can be initiated register flow path by the HSS/HLR place of this tunnel in the mobile network, so that the IP terminal of mobile network's identification information of this IP terminal of sign such as MSISDN/ISDN correspondence is attached on the IP access network in HSS/HLR, simultaneously, the link block of Serving SM-IW also needs the IP address information of Serving SM-IW or mobile network's identification information is registered among the HSS/HLR, exhales route as the short message of the subsequent movement network beginning.
The IP terminal can adopt SIP (SIP) login mechanism to be initiated to the register flow path of HSS/HLR.
When this IP terminal is not in roaming state, the IP terminal is passed through BS, ASN GW and short message interconnecting gateway connect and IP terminal and short message interconnecting gateway are registered in the mobile network process such as above-mentioned step 1 are basic identical to the description of step 8, just in step 7, the IP terminal can not receive the Tunnel_Establish_Request message of the IP address information that carries the short message interconnecting gateway, so, when the IP terminal has been opened short message service, the short message interconnecting gateway that presets of this IP terminal passes through BS, ASN GW foundation is connected with the IP terminal, this connection can connect for tunnel as shown in Figure 1, carries the Tunnel_Establish_Response message that successful information is set up in the tunnel by presetting the short message interconnecting gateway to the transmission of IP terminal.Like this, in step 1-8, the short message interconnecting gateway that presets of IP terminal is registered to its IP address information or mobile network's identification information among the HSS/HLR, the route of exhaling as the subsequent movement network beginning.
Among Fig. 3, the short message beginning that is in the IP terminal under the roaming state in the IP terminal exhales flow process as follows:
Send short messages to Serving SM-IW in step 2-1, IP terminal by the tunnel that safety connects.
From its stored relation, obtain the mobile network's identification information such as the MSISDN/ISDN of this IP terminal according to the IP address in the short message to step 2-2, Serving SM-IW, then, ServingSM-IW is sent to the SMS-IWMSC among the mobile network with the mobile network's identification information and the short message encapsulation of this IP terminal.
In this step, mobile network's identification information of this IP terminal and short message can be packaged into SMPP packet or SS7 MAP packet and be sent to SMS-IWMSC among the mobile network.
To step 2-3, SMS-IWMSC the short message of its reception is continued to be forwarded to SMSC (Short Message Service Center) among the mobile network, and send Delivery Report (transmitting report) to Serving SM-IW simultaneously.
Receive Delivery Report to step 4, Serving SM-IW, and from its stored relation, obtain corresponding IP address, and Delivery Report is continued to be transmitted to the IP terminal according to this IP address according to the mobile network's identification information among the Delivery Report.
When the IP terminal is in non-roaming state, the short message of the IP terminal beginning exhales the process of flow process and above-mentioned steps 1 basic identical to the description process of step 4, and what just Serving SM-IW need be replaced with the IP terminal presets short message interconnecting gateway Provisioning SM-IW.
