Abstract

The embodiment of the invention discloses an access control method and access control equipment, and relates to the technical field of wireless communication. The method and the equipment are used for solving the problem that a terminal cannot perform access control because access class barring (ACB) parameter configuration of a conventional type has no ACB parameter corresponding to a current radio resource control (RRC) connection establishing reason. In the method, when the terminal does not store the ACB parameter corresponding to the current RRC connection establishing reason, the terminal selects a type of the ACB parameter used for access control from the stored ACB parameters, or a network side transmits the ACB parameter of the conventional type or the ACB parameter of a newly defined type to the terminal; and the terminal performs the access control by using the ACB parameter of the newly defined type when the current RRC connection establishing reason does not belong to the RRC connection establishing reason corresponding to the ACB parameter of each existing type. By adopting the method, the problem can be solved.

Description

Connection control method and equipment

Technical field

The present invention relates to wireless communication field, relate in particular to a kind of connection control method and equipment.

Background technology

No matter be universal mobile telecommunications system (Universal Mobile Telecommunications System at present, UMTS) still be Long Term Evolution (LTE) system, wireless access network (RAN) side has all been introduced access control mechanism, when great amount of terminals inserts when causing not enough and the congested or network of RAN access-in resource to think need to forbid that some terminal inserts simultaneously, network will start that access control mechanism limits and the access of homogenizing distribution terminal.At present the access control scheme in UMTS and the LTE system all is based on the access grade of terminal (Access Class AC) forms, and is referred to as access grade and forbids (Access Class Barrinig, ACB) mechanism.

For terminal (UE), each terminal all can have an AC, and AC is the number in (0...9).This AC can be kept at terminal user identification module (SubscriberIdentity Module, SIM)/universal subscriber identity module (Universal Subscriber Identity Module, USIM) card in.In addition, some terminal also may have special AC (11...15).Terminal with special AC has higher priority in some applications.

For the UMTS system, the scheme of ACB is all can provide whether the be under an embargo indication of (barred) of this AC at each AC (0...15) in the ACB parameter, and is as shown in the table:

The ACB parameter of UMTS system is included in the system information block (SIB) 3, when network side monitor take place congested or other need forbid scene that some terminal inserts the time, network side can be broadcasted the ACB parameter in SIB3.After terminal read the ACB parameter of carrying among the SIB3, before initiating access at random, the AC that can be kept in the SIM/USIM card according to the content and the terminal of ACB parameter among the SIB3 judged whether to be allowed to insert by network.

For the LTE system, what be that the terminal of 0...9 uses for AC is identical access probability (ac-BarringFactor)+and identical mode of forbidding duration (ac-BarringTime), for AC be 11...15 the terminal use be the mode of bitmap (bitmap).As follows:

The ACB parameter of LTE system is included among the SIB2, when network side monitor take place congested or other need forbid scene that some terminal inserts the time, network side can be broadcasted the ACB parameter in SIB2.After terminal reads the ACB parameter of carrying among the SIB2, the terminal that for AC is 0...9 is before initiating to insert at random, at first generate a random number rand (span is 0≤rand＜1), if rand＜ac-BarringFactor, then terminal can be initiated to insert, otherwise starts timer Tbarring, the * ac-BarringTime of the duration of Tbarring=(0.7+0.6*rand), in the timer scope, the Radio Resource of terminal control (RRC) layer can not initiate to insert at random again.For AC is the terminal of 11...15, forbids peculiar one corresponding in (ac-BarringForSpecialAC) information of ratio when the access control of the special access control in the ACB parameter and is changed to 0, just can directly initiate to insert.Otherwise, terminal can generate a random number rand (span is 0≤rand＜1), if rand＜ac-BarringFactor, then terminal can be initiated to insert, otherwise start timer Tbarring, the * ac-BarringTime of the duration of Tbarring=(0.7+0.6*rand), in the timer scope, the rrc layer of terminal can not initiate to insert at random again.

For UMTS and LTE system, network can be broadcasted polytype ACB parameter in SIB, and every kind of ACB parameter and a kind of RRC connect that to set up reason corresponding.For the LTE system, the RRC connection is set up reason and is comprised caller data (MO-Data), caller signaling (MO-signaling) etc., and concrete ACB parameter is as follows:

For the UMTS system, concrete ACB parameter is as follows:

The RRC connection is set up former because the ACB parameter of caller:

The RRC connection is set up former because called ACB parameter:

The RRC connection is set up former because the ACB parameter that parameter (Location/Registration Parameters) put/registered to signaling bit:

The reason that the RRC that terminal specifically uses the ACB parameter of which kind of type to be based on the terminal initiation connects the request of foundation is that reason is set up in the RRC connection.RRC connects that to set up reason be that Non-Access Stratum (NAS) layer by terminal is notified to rrc layer, and rrc layer can connect to set up and carries this RRC in the request message and connect and set up reason at RRC.For example, for the LTE system, present RRC connects and sets up the RRC that carries in the request message and connect that to set up reason as follows:

EstablishmentCause::＝ ENUMERATED{

emergency，highPriorityAccess，mt-Access，mo-Signalling，

mo-Data，spare3，spare2，spare1}

For the UMTS system, present RRC connects and sets up the RRC that carries in the request message and connect that to set up reason as follows:

As mentioned above, for example, for the LTE system, when terminal connects when setting up request initiating RRC, if it is former in MO-Signalling that the RRC connection of NAS layer indication is set up, terminal will use the access control of the caller signaling of broadcasting among the SIB to forbid (ac-BarringForMO-Signalling) parameter so.For the UMTS system, when terminal connects when setting up request initiating RRC, set up former because Location/Registration is when upgrading if RRC connects, terminal will be used the Location/Registration parameter of broadcasting among the SIB so.Set up former because when called if RRC connects, terminal will use the paging of relevant access control to allow (Paging Permission with Access Control Parameters) parameter so.The reason of other type can be used regional special access limiting parameter (Domain Specific Access Restriction Parameters).

Machinery compartment (M2M, Machine-to-machine) communication is as a kind of novel communication theory, its objective is that the communication technology with number of different types organically combines, as: machine is to machine communication, machine control communication, man-machine interaction communication, mobile interconnected communication, thus the development of promotion social production and life style.The business of estimating following Human To Human's communication may only account for 1/3 of whole terminal market, and the communication of bigger quantity is machinery compartment (little bandwidth system) communication service.

Some characteristics that the current MTC communication of recognizing may exist have: and Machine Type communication (Machine Type Communication, MTC) number of devices is much larger than normal terminal quantity; MTC equipment has the low priority characteristic; The transfer of data that MTC equipment and network side carry out is less demanding to real-time, has the time tolerance that is:; The MTC plant capacity is limited, requires extremely low power consumption; Or the like.The MTC equipment of a reality can have above-mentioned one or more characteristics.

Think that at present it is congested to insert the RAN side that causes simultaneously for MTC equipment, need to use the access grade of expansion to forbid that (Extended Access Barring, EAB) parameter is provided with the access control parameter separately for MTC equipment exactly.While is commonly considered as low priority for the MTC equipment that uses the EAB parameter, it be time delay tolerance (delay tolerant) that the reason of asking is set up in initiation RRC connection.Consider the low priority characteristic of MTC equipment, when a large amount of MTC equipment insert when causing Access Network congested simultaneously, terminal judges whether to be allowed to access according to the EAB parameter earlier, if continue so to use the ACB parameter to judge whether to be access in.Have only after the dual judgement of having passed through EAB and ACB parameter, MTC equipment just is allowed access to network.

The NAS layer obtains the RRC connection according to certain rule mapping and sets up reason based on current type of call/NAS process.Such as, the type of call of terminal is signaling/data, but this terminal is again the low priority terminal, when terminal was initiated the RRC connection of the type, NAS will notify rrc layer: RRC to connect and set up reason was delay tolerant so.

In realizing process of the present invention, the inventor finds to exist in the prior art following technical problem:

The RRC connection that current MTC equipment is initiated is commonly considered as low priority and is inserted, and it is delay tolerant that reason is set up in the RRC connection.In the present system, the ACB parameter all is to be connected with RRC that to set up reason corresponding, so when the RRC of MTC equipment connects when setting up reason and being delay tolerant, set up former because the ACB parameter of delay tolerant correspondence owing to there is not RRC to connect in the present ACB parameter configuration, so terminal can't determine to use the ACB parameter of which kind of type, and then can't carry out access control.
