The technical scheme that the above-mentioned implementing procedure instance of the present invention is disclosed because MS need not the switching command that reception sources network control network element sends, has been avoided the handoff failure that causes owing to cell-of-origin wireless environment rapid deterioration, has improved quality of service.
Below in conjunction with concrete application implementation example and accompanying drawing, said method, system and device are further explained.
Application implementation example one:
Should use among the embodiment, be GAN in order to avoid authorize Access Network, and exempting from the authorization control network element is GANC, and wireless access network is GERAN, and the controlled in wireless network element is that the situation of BSS is an example, and handoff procedure is an example with the situation of SGSN intra.
In the GAN network, general access IP network provides WAP, and portable terminal is connected to GANC through general access IP network (Generic Access IP Network).
Referring to Fig. 7, the method flow diagram of Fig. 7 for switching between network in the application implementation example one.As shown in Figure 7, this flow process comprises the steps:
Step 701 when MS carries out measurement report in the GERAN sub-district, finds that the GAN mode service exists.
In this step, when the MS with one or more movable packet sessions in the GERAN sub-district, MS can use adjacent area cell list information to carry out measurement report, thereby finds the existence of GAN mode service.
Step 702～step 703, MS completes successfully the GAN registration, and when satisfying report condition, the BSS in GERAN sends the measurement report of GAN sub-district.
Wherein, When MS completes successfully the GAN registration; Can obtain absolute wireless frequency point number (ARFCN, Absolute Radio Frequency Channel Number)/base station transceiver identification code (BSIC, Base transceiver Station Identity Code) from the GANC of its registration; If the ARFCN of this GANC is included in the Lin Qu tabulation of this GERAN sub-district, MS can select a measurement report that sends the GAN sub-district opportunity.
MS for GAN preferential (GAN-preferred) after MS completes successfully registration, can send above-mentioned measurement report immediately; And for the MS of GERAN preferential (GERAN-preferred), MS can just send above-mentioned measurement report when the GERAN cell quality is reduced to a certain degree.
Wherein, when MS sends the measurement report of GAN sub-district to BSS, can the reception priority class of traffic (RxLev, Received signallevel) of this GAN sub-district be set to highest 63.
Step 704, BSS when decision is initiated to the grouping switching of GAN, sends grouping handoff request (PS Handover Required) or redirect request (Relocation Required) to SGSN according to the measurement report from MS.
Wherein, can carry switch reasons value, cell-of-origin sign in grouping handoff request or the redirect request, Target Cell Identifier and BSS are to the transmission container of GANC.For the switching in the SGSN, include only the information of Access Network part in this transmission container.
Step 705, SGSN sends grouping handoff request (PS Handover Request) according to grouping handoff request or redirect request from BSS to GANC.
Wherein, Whether SGSN discerns the route district through Target Cell Identifier and changes after receiving the grouping handoff request or redirect request from BSS, if the route district does not change; When then SGSN sends the grouping handoff request; Carry original packet TMSI (P-TMSI, Packet Temporary Mobile Subscriber Identity) and logic circuit sign (TLLI, Temporary Logical Link Identifier) in this grouping handoff request; If the route district changes, then SGSN is before sending the grouping handoff request, and SGSN is that MS distributes new P-TMSI, and obtains new TLLI based on this P-TMSI, and new P-TMSI and TLLI are carried in the grouping handoff request that sends to GANC.
In addition, in order to realize the seamless switching of Business Stream, no matter whether the packet flow context of all MS (PFC, Packet Flow Context) be movable, all is included in this message.
Step 706 after GANC receives the grouping handoff request from SGSN, is that MS distributes GAN (GA-PSR) transmission channel that divides into groups, and authorizes the Access Network packet transmission channel to notify exempting from of being distributed to MS.
Based on total quality of service configuration (ABQP, Aggregate BSS QoS Profile) of each PFC, whether target GANC decision activates GAN grouping (GA-PSR) transmission channel.If distributed a GA-PSR transmission channel, this channel is used to support the packet data streams needs of all requested PFC.
Step 707, MS confirms to send upstream data to GANC according to the GA-PSR of GANC notice.
In this step, can further include: MS stops to send upstream data to BSS.
Step 708 after GANC confirms the GA-PSR that is distributed successfully is notified to MS, is sent grouping to SGSN and is switched and accomplish (PS Handover Complete) message, and notice SGSN grouping is switched and accomplished.
Wherein, carry TLLI in the grouping handoff completion message, P-IMSI and Target Cell Identifier etc.GANC confirms the method that the GA-PSR that is distributed successfully is notified to MS can be had multiple, as comprising following two kinds at least:
Method one:
In the step 707, MS to GANC echo reply response message, after GANC receives this response message in the step 708, confirms that the GA-PSR that will distribute successfully is notified to MS after receiving the GA-PSR that GANC notice distributed.Wherein, response message can be the GA-PSR handoff completion message, also can be the resource allocation response message.
Method two: in the step 707, MS receives GANC and notifies the GA-PSR and the decision-making that are distributed in the GAN Access Network, behind the transmission upstream data, to send upstream data to GANC; After GANC receives this upstream data in the step 708, confirm the GA-PSR that distributes is successfully notified to MS.
In addition, for the backwards compatibility of guarantee agreement,, between step 707 to step 708, carry out following steps with reference to existing procedure:
Step 107b, GANC sends grouping switching request response or redirect request response to SGSN.
After step 108b, SGSN receive the grouping switching request response from GANC, send the grouping handoff response to BSS.
After step 109b, BSS receive the grouping handoff response, send the grouping switching command to MS, notice MS divides into groups to switch.
Just MS no longer handles this switching command in the embodiment of the invention.
Step 709 after SGSN receives the grouping handoff completion message, is notified the BSS finishing switching, can discharge the resource of original distribution.
So far, switching flow finishes.
More than internetwork changing method in the application implementation of the present invention example one is described in detail, more internetwork switched system in the application implementation example one of the present invention is described in detail below.
