In 3GPP meeting, successfully relevant data communication congestion control mechanism is applied in project verification research, mainly comprises following research contents:
Analyze use-case and the potential demand of the special applications initiating communication of allow/restriction operator definition;
Analyzing existing access control mechanism can not make network indicating user terminal (User Equipment, UE) go the defect of allow/restriction special applications access;
Consider the backwards compatibility of existing access control mechanism.
At present, there is following several access control mechanism in Radio Access Network (Radio Access Network, RAN) side:
First, Long Term Evolution (Long Term Evolution, LTE) restriction of the access grade in version (Rel) 8 (Access Class Barring, ACB) mechanism, its operation principle is: base station broadcast limitation rate (Barring rate), at evolved universal terrestrial radio access network (Evolved Universal Terrestrial Radio Access Network, E-UTRAN) in, Barring rate is probability grade, at universal terrestrial access network (universal terrestrial access network, UTRAN) in, Barring rate is access grade (Access Class) and binding hours (barring time) etc., UE receives the barring rate in broadcast, judging whether according to barring rate can access network, concrete, and in E-UTRAN, UE oneself produces random number, the random number of generation and the probability grade of receiving are contrasted, and then determine whether can access, in UTRAN, UE compares the Access Class of oneself and the Access Class receiving, and then whether decision can access network.
The ACB mechanism for circuit domain rollback business (CSFB, CS fallback) (ACB for CSFB) in the second, R10, this mechanism is only applicable to the access for CSFB in E-UTRAN, is similar to ACB mechanism.
The 3rd, waiting timer (the extended wait timer) mechanism of the expansion in R10, its operation principle is: whether reason (RRC establishment cause) value is set up in the Radio Resource control of carrying when base station is accessed according to UE is time delay tolerance (Delay tolerant), determines whether refusing RRC connection foundation request or discharge RRC connecting.
The 4th, access limitation (Extended Access Barring, the EAB) mechanism of the expansion in R11, its operation principle is: base station broadcast EAB parameter, comprises EAB type (category) information (EABcategory information can be provided by core net); The UE that receives EAB parameter need to carry out EAB to Access Layer (AS) instruction to the access of application layer initiation and check, AS is according to public land mobile network mark (the Public Land Mobile Network ID at the current place of UE, PLMN ID), the information such as local public land mobile network mark (Home Public Land Mobile Network ID, HPLMN ID) and the EAB category that receives determines whether the access that application layer is initiated can be stoped by EAB mechanism.If access is not stoped by EAB mechanism, UE also will judge whether this access is stoped by ACB mechanism.
Existing 3GPP agreement has also proposed general Non-Access Stratum (Non-Access Straum, NAS) mobile management (Mobility Management) congestion control mechanism, propose under general network over loading condition, network can be refused any Mobility Management signaling request of UE, and in refuse information, carries mobile management rollback timer (Mobility Management back-off timer) information.
From prior art, the congestion mechanism such as the ACB of existing RAN side all can not be differentiated application layer message, therefore can not be for being used for carrying out access control.
