A method for implementing priority access of PACA users includes: makes classification for users; when the resources of wireless channel or circuit are not enough, dismantles the link of low grade user, makes priority access to the released resource for the PACA calling or called user. The method can make the PACA user no need to queue in BSC, and can meet special user' requirement.
Description
Technical field
The present invention relates to wireless communication field, refer to the method for a kind of PACA of realization (Priority Access andChannel Assignment is preferential to be inserted and channel assignment) user priority connecting system especially.
Background technology
The cellphone subscriber decides, when called, need take radio channel resource and land circuit resource, wherein, the land circuit resource is distributed by moving exchanging center MSC, radio channel resource is distributed by base control BSC, if be not assigned to corresponding resource, calling can't be set up.
For some special users (as the higher-level user in the army net), need can guarantee also when resource is not enough that it gets through.
Realize that according to agreement user priority inserts in the prior art.
When mobile phone was done caller requirement access, base control (BSC) was checked resource status, structure CM service request (CM Service Req) message informing moving exchanging center MSC.Moving exchanging center MSC is checked message parameter, finds that radio channel resource is not enough, and the signatory PACA business of user, structure PACA Command message informing base control BSC, and MSC carries out mark (user ranks at BSC) to the user simultaneously.Base control BSC ranks to PACA user after receiving PACA Command message.BSC checks the radio channel resource situation, when available channel, finds out highest-ranking PACA user from formation, sends out the message informing mobile phone and initiates again to begin to call for to ask, and inserts.When base control BSC finds that the PACA Subscriber Queue changes, the mark that needs the cancellation of notice moving exchanging center MSC that the user is done.Find the user profile (state or position) of having done mark when moving exchanging center MSC variation has taken place, also want informing base station control system BSC that the user is deleted from formation.
PACA user initiate the beginning exhale, flow process as shown in Figure 1:
When service request is initiated in user's caller, base control BSC checks the radio channel resource situation, corresponding wireless environment and resource parameters (Radio Environment and Resources) are set, insert by CM business request information (CM Service Req) notice moving exchanging center MSC customer requirements;
Moving exchanging center MSC is checked wireless environment and resource parameters (Radio Environment andResources), discovery does not have available radio channel resource, and user's PACA business of contracting, sending out a PACACommand message informing base control BSC user is PACA user;
Base control BSC ranks to PACA user after receiving PACA Command message, then by PACA Command ACK message informing moving exchanging center MSC;
Moving exchanging center MSC is provided with sign after receiving PACA Command ACK message, and record PACA user ranks at base control BSC;
After base control BSC finds that idle radio channel resource is arranged, from formation, take out high level PACA user, notify the user to initiate again to begin to call for to ask, insert.
Base control BSC initiates user PACA state variation flow process as shown in Figure 2:
Change when base control BSC finds User Status (user stop the beginning exhales or BSC breaks down), base control BSC deletes the user from formation, send out PACA Update message informing moving exchanging center MSC;
After moving exchanging center MSC is received PACA Update message, the mark that cancellation is done the user.
Moving exchanging center MSC is initiated user PACA state variation flow process as shown in Figure 3:
The PACA information of finding to be the user of mark as MSC change (for example user's roaming, user again the PACA beginning exhale, MSC side fault etc.), he moving exchanging center MSC informing base station control system BSC makes amendment to user's PACA information;
After base control BSC receives message, the user is deleted from formation, return acknowledge message then.
The shortcoming of prior art one:
If 1 mobile subscriber who is conversing does not initiatively finish conversation, PACA user can't insert;
2, PACA user waits for that in base control BSC queuing other users finish conversation and discharge resource, and access speed is slow;
3, because the realization flow complexity does not have PACA to do called flow process in the agreement.
