Embodiment
General processing scheme is each after the NAS of UE layer initiation business now, and the AS layer calculates current access state according to Fig. 1 flow process, and is concrete:
Step 101, AS layer judge whether current UE exists Subscriber Identity Module;
In the embodiment of the invention, described Subscriber Identity Module is specially SIM card or usim card, below is that example describes with the usim card.
If have usim card in step 102 UE, then according to UE access grade information and the current resident network type stored in the card, judge in the current card which access grade actual available in the access grade is, judgment principle is: UE resides in home network (HPLMN, Home Public Land MobileNetwork) time, access grade 0-9 and 11-15 are effective, when the national code of residing network is identical with the HPLMN national code, access grade 0-9 and 12-14 are effective, and access grade 0-9 is effective during resident other network.
Step 103, determine the access grade that normal call can be used;
In this step, after getting access to the access grade that UE can use, corresponding one by one relatively with being done of system information broadcast by bar tabulation (being the access grade tabulation that network is forbidden), from the available access grade that step 102 is obtained, reject those access grades of being forbidden by network.
Further, determine the access state of UE to comprise the access state of normal call and the access state of urgent call, but access state is divided into access state and can not access state two kinds according to available access grade.If the tabulation of relatively later more available access grade is not empty, but thinks that then the access state of normal call is an access state, and the access grade of maximum remaining in the tabulation is preserved as best access grade, in the time of initial random access, use.
Step 104, determine the access grade that urgent call can be used;
According to the information of being tabulated of the system information of Web broadcast, do contrast again, whether limit the judgement of urgent call with available access grade in the usim card by bar.
If judge among the UE in step 105 step 101 and do not have usim card, think that then the access state of normal call is for can not access state, and according to the AC[10 that is tabulated by bar of the system information of Web broadcast] (the access grade tabulation in the system information comprises 0-15 totally 16 grades, wherein access grade 10 is called for short AC[10], be used as the sign position of restriction urgent call) whether limit urgent call when whether being judged no usim card by bar.
Step 106, metered call access state result;
Comprise the access state that writes down normal call and the access state of urgent call.
This processing method causes the generation of following two kinds of situations:
1, the NAS layer is not known AS layer access state, might insert the not permission stage to UE at the AS layer and repeat to initiate professional;
If what the NAS layer was initiated is general business, by AS layer refusal back NAS layer notice UE service fail, to not influence of flow process.But UE does not also know failure cause, might make repeated attempts to initiate business, and each NAS layer all can make a call to the AS layer, and the AS layer just need thresh the access control of repetition and calculate, and causes redundant the processing, and access control efficient is low.
2, when the access state of UE changes, the NAS layer can't be known this change, to some business can not in time be initiated;
The access state variation that may occur comprises two kinds: a. access state takes place by being linked into the variation that can not insert; B. access state is by being linked into the variation that can insert.For (a) this situation, the influence that causes is identical with (1) this situation.For (b) this situation, because the NAS layer is not known the variation of the access state of AS layer, some are owing to access is led to the failure by bar, but becoming in access needs the business initiated immediately after can inserting, can not initiate immediately, the traffic affecting instantaneity, access control efficient is low.
