Embodiment
Basic thought of the present invention is: the MSS of NCS request gravity treatment is that described UTS creates connection; MSS is to the IP address information of SA transmission for described UTS.
For making purpose of the present invention, technical scheme and advantage are clearer, and by the following examples and with reference to accompanying drawing, the present invention is described in more detail.
Fig. 2 is the flow chart that the packet switching Mobile Access Network of the embodiment of the invention one triggers the method for routing optimality, as shown in Figure 2, this example has been described when UTS carries out exchange of media class business, initiate the situation of routing optimality operation, wherein RNS1 is source radio node system, NCS1 is the source network control system, MSS1 is the source media exchange system, RNS2 is the Target Wireless node system, NCS2 is the objective network control system, MSS2 is the target medium switching system, and the method for the packet switching Mobile Access Network routing optimality of this example mainly may further comprise the steps:
Step 200, before UTS initiates business or in the execution business procedure, NCS1 obtains the UTS contextual information, such as the IP information (can be the forms such as IPv4 address, IPv6 address or IPv6 prefix, may exist a plurality of) for UTS, and/or International Mobile Subscriber Identity (IMSI), the address information that also can comprise the SA of the business use on the UTS, such as the domain name of SA, or the IP address of SA, the link information of UTS etc. also can be comprised.
The UTS contextual information also can (receive the inquiry of NCS) passively or directly or indirectly (be transmitted by other network elements by one of UTS, SA and MSS or combination on one's own initiative, pass to NCS such as UTS through MSS, or SA passes to NCS by PDS and MSS) offer NCS, as passing to NCS by one or more signaling messages.
If there is not the routing update set-up procedure, then NCS1 may need some parameter of static configuration, such as the address information of SA.
Step 200 is optional step.
Step 201, UTS sends measurement report to RNS1, such as send Measurement Report message to RNS1, comprises the information such as signal strength signal intensity of the peripheral cell that UTS measures in the message;
Step 202, RNS1 determines to carry out according to measurement report information and switches, then send hand off signaling to NCS1, such as sending Handover Required message;
Step 203, if NCS1 has selected new NCS2 that network control is provided, then NCS1 initiates to switch the forward operation to NCS2, such as sending Forward Relocation message, this message is carried the UTS contextual information, the UTS contextual information (can be the IPv4 address such as the IP information for UTS, the IPv6 address, or the form such as IPv6 prefix, may exist a plurality of) and/or International Mobile Subscriber Identity (IMSI, International Mobile Subscriber Identification Number), the address information that also can comprise the SA that the business on the UTS is used, such as the domain name of SA, or the IP address of SA, also can comprise the link information of UTS etc.;
Step 204, if carried out step 203, then controlled entity is NCS2, otherwise controlled entity is NCS1, and controlled entity (present embodiment is NCS2) is selected new MSS2 and sent the establishment connection message to MSS2, such as sending Create Session Request message, this message can be received by the IGW of MSS2, if the PS Access Network has been disposed PDS, then this message also can be received by the PDEA of MSS2, and this message is carried the UTS contextual information;
Here, controlled entity selects new MSS2 to accuse the new IGW of entity selection processed, also can select new TGW.Among the present invention, select new MSS to be, reselect the IGW among the MSS, or reselect IGW and part TGW, or reselect IGW and whole TGW.The new MSS of the selection of following embodiment also is identical implication, no longer one by one explanation.
Step 205, MSS2 initiates the routing update notification procedure according to the UTS contextual information of receiving and upgrades with the professional route needs of notice SA, specifically can use Fig. 5 and any mode shown in Figure 6 to notify the professional route of SA to need to upgrade, SA can obtain new IP information etc. by the routing update notification procedure, such as new IPv4 address, IPv6 address or IPv6 prefix etc., thus the route of renewable business;
Step 206, SA initiates the far-end renewal process according to the new IP information that obtains in service network;
Concrete far-end renewal process is decided according to service network, if service network is IP Multimedia System IMS (IP Multimedia Sub-system) network, then the far-end renewal process can be to send reINVITE (heavily inviting) message, and new address information can carry to notify far-end by Contact (contact person) header field and the message body of message.
Step 207, after step 204, or after step 205, MSS2 returns the establishment success message, such as sending Create Session Response message, one or more link informations of carrying MSS2 are such as the IP address, also can comprise port numbers and/or connection identifier information, can not adopt pre-configured port numbers when not containing port numbers in the link information;
Step 208, controlled entity NCS2 receives the establishment success message, then notifies RNS2 to prepare to switch, such as sending Handover Request message, one or more link informations of carrying MSS2;
Step 209, RNS2 prepares resource, comprises and the wireless connections resource of UTS, after being ready to complete, then notifies controlled entity NCS2 to be ready to complete, and such as sending Handover Request Acknowledge message, message is carried the link information of RNS2;
Step 210, if carried out step 203, then NCS2 sends the forward response to NCS1, such as sending Forward Relocation Response message;
Step 211, NCS1 receives the message that is ready to complete of the forward response message of step 210 or step 209, NCS1 sends to RNS1 and agrees to switch message, such as sending Handover Command message;
Step 212, RSN1 sends switching notice to UTS, such as sending Handover Command message;
Step 213 after UTS is modulated to Target cell, sends handoff completion message to RNS2, such as sending Handover Complete message;
Step 214, RNS2 is sent completely notification message to controlled entity NCS2;
Step 215, controlled entity NCS2 sends to MSS2 and confirms success message, and such as sending Modify Bearer Request message, message is carried the link information of RNS2;
So far, new media connect 3 to be set up, and these media connect and also comprise UTS to the wireless connections of RNS2.
Step 216, SA has received from the renewal of service network and has finished message, thereby business datum is routed on the new IP information, also be on the IP information that provides of step 205, this IP information be so that business datum can be routed to MSS2, and the time point that SA receives this message may be the random time point after the step 206;
Concrete far-end upgrades complete process to be decided according to concrete service network, if service network is IP Multimedia System IMS network, then far-end renewal complete process can be to receive 200OK message.
So far, new media connect 4 to be set up, and UTS can connect 3 media path and the far-ends that are connected 4 formations with media by media and proceed business.Because the establishment mode of media connection 4 is prior art, repeats no more the concrete mode of its establishment.
