(1) processing of BS side
The BS of the service when withdrawing from the Idle pattern and the BS that enters the idle pulley service are under the situation of same BS, and the BS of the service when withdrawing from the Idle pattern can inform in the HO Process Optimization parameter in returning RNG-RSP (ranging response) message of eating dishes without rice or wine that MS can omit SBC in the access procedure and consult (capability negotiation), REG and consult in (log-on consultation), the discrimination weight flow process at least one.
Simultaneously, because the BS of the service when withdrawing from the Idle pattern and the BS that enters the idle pulley service are same BS, the BS of the service when then withdrawing from the Idle pattern can not need once more to MS notification section ability parameter, to reach the purpose that reduces control RNG-RSP message size.
The BS of the service when for example, withdrawing from the Idle pattern in the RNG-RSP message that MS sends, do not carry following parameter one of at least: SBC TLV initiatively, the REG TLV of other parameters except that C ID undated parameter and SA ID undated parameter.
The BS of the service when withdrawing from the Idle pattern and the BS that enters the idle pulley service are under the situation of same BS, and it is mutual that the BS of the service when withdrawing from the Idle pattern can ignore the SBC that eats dishes without rice or wine, and can not carry the SBCTLV of negotiation in RNG-RSP.
Similarly, it is mutual that the BS of the service when withdrawing from the Idle pattern can ignore the REG that eats dishes without rice or wine, and can not carry the REGTLV of negotiation in RNG-RSP.
The handling process of BS side has been shown among Fig. 2.
As shown in Figure 2, the processing of BS side specifically may further comprise the steps:
Step S202:BS receives that MS asks to withdraw from the MS contextual information that the Idle mode message is preserved to the PC request, and PC returns the context message of this MS to BS by IM Exit MS State Change Rsp;
Step S204: withdraw from Serving BS (BS that reenters) that Idle reentries and compare according to the BS ID (Entry Idle BS ID) and the BS ID of oneself of the Idle pattern that enters of carrying in the message, if two BS ID unanimities, illustrate that MS enters the Idle pattern and withdraws from the Idle pattern on same BS, proceed to step S206, otherwise, jump to step S214;
Step S206: the follow-up SBC negotiation flow process of eating dishes without rice or wine is ignored in indication in the HO Process Optimization parameter of the BS of the service when withdrawing from the Idle pattern in giving the RNG-RSP message of MS;
Step S208: the follow-up REG negotiation flow process of eating dishes without rice or wine is ignored in indication in the HO Process Optimization parameter of the BS of the service when withdrawing from the Idle pattern in giving the RNG-RSP message of MS;
Step S210: the BS of the service when withdrawing from the Idle pattern can not carry SBCTLV initiatively in RNG-RSP;
Step S212: the BS of the service when withdrawing from the Idle pattern can not carry the REGTLV of other parameter except that CID undated parameter and SAID undated parameter in RNG-RSP;
Step S214: the BS of the service when withdrawing from the Idle pattern or not ignore the SBC that eats dishes without rice or wine mutual perhaps carries the SBCTLV of negotiation in RNG-RSP, both can not the whole province slightly.
Step S216: as the BS of the service when withdrawing from the Idle pattern or not ignore the REG that eats dishes without rice or wine mutual, perhaps in RNG-RSP, carry the REGTLV of negotiation, both can not the whole province slightly.
Step S218 sends IM Exit MS State Change Rsp message.
(2) processing of PC side
When the ID of the BS of the service of PC when the Idle pattern is withdrawed from judgement with enter idle pulley preserve the ID of serving BS broadcasts when identical, can in IM Exit MS State ChangeResponse message, not carry SBCRSP Context and REGRSP Context parameter, but need carry SBCREQ Context and REGREQ Context parameter.
And when the ID of the BS of the service of PC when the Idle pattern is withdrawed from judgement with enter idle pulley preserve the ID of serving BS broadcasts when inequality, the PC side still needs carry the MS contextual information of complete preservation in IM Exit MS StateChange Response message.
Show in detail the handling process of PC side among Fig. 3.
As shown in Figure 3, the processing of PC side specifically may further comprise the steps:
Step S302:PC receives the IM Exit MS State Change Request message of BS side, the ID of the BS of the service when carrying MS in the message and withdrawing from the Idle pattern, and this message is the contextual information of BS to PC request MS;
The ID of the BS of the ID of the BS that enters the Idle pattern that step S304:PC will before preserve (EntryIdle BS ID) and the service when withdrawing from the Idle pattern compares, if consistently carry out step S306, if the inconsistent step S308 that carries out;
Step S306: when the two was consistent, PC can not carry SBCRSP Context and REGRSP Context parameter in IM Exit MS State ChangeResponse message, but need carry SBCREQ Context and REGREQ Context parameter;
Step S308: when the two was inconsistent, PC need carry the contextual information of the MS of all preservations in IM Exit MS StateChange Response message; And
Step S310:PC sends the BS of the service of IM Exit MS State Change Response message when withdrawing from the Idle pattern.
By above technical scheme, the present invention has optimized the handling process of base station when entering the Idle pattern and withdrawing from the Idle pattern under same base station, receives by the parameter meter that carries in the minimizing message simultaneously and has lacked the bandwidth consumption of eating dishes without rice or wine with the R6 mouth.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
