The connection control method of a kind of UE and equipment
Technical field
The present invention relates to communication technical field, particularly relate to connection control method and the equipment of a kind of UE.
Background technology
At LTE(LongTermEvolution, Long Term Evolution) in system, to UE(UserEquipment, subscriber equipment) access control be divided into initial access control and the call access control based on carrying.
One, initial access control.
The AC(AccessClasses of UE, access grade) there is AC0 ~ AC15, and all UE have been assigned with one among AC0 ~ AC9, some UE with specific high priority may be distributed one or more special access class (AC11 ~ AC15) in addition.When network occurs congested, network side is broadcasted AC-bar(access grade and is forbidden in system message) information, and by RRC(RadioResourceControl, wireless heterogeneous networks) introduce access probability to the access of control UE in connection establishment process; Such as, UE, when initiating RRC connection establishment request, according to AC-bar information and the AC rank of self, judges whether community is prohibited to access; Suppose the AC-barfactor(coefficient in AC-bar parameter) be that 0.3, UE does not belong to AC11 ~ AC15, and the random number produced is not less than 0.3, then think that this community is prohibited, UE does not send RRC connection establishment request message; Otherwise UE can send RRC connection establishment request message to network side.
Further, network side, after receiving the request of RRC connection establishment, may send RRC connection refused message, then causes connection establishment failure; Such as, when there is network congestion, network side is treated with a certain discrimination according to the connection establishment reason in RRC connection establishment request message, if emergency(emergency) or the access of highPriorityAccess(high priority) AC11 – 15, then network side allows it to access, and then refuses its access under other set up reason.
Two, based on the call access control of carrying.
Call access control is used for judging when receiving new radio bearer to allow access or refusal access; When carrying out acceptance judging, the QoS(QualityofService of the overall condition (comprising resource service condition and resources left situation) of radio resource state, ongoing session need be considered, service quality) information such as situation and the QoS demand of asking newly-built radio bearer.By call access control, can when Radio Resource be permitted, while the QoS ensureing access bearer, the carrying that access as much as possible is new, and the qos requirement ensureing access bearer, thus improve the capacity of system and the utilance of resource.
EPS(EvolvedPacketSystem, the grouping system of evolution) carrying is divided into default bearing and dedicated bearer; Default bearing meets the data of acquiescence QoS and user's carrying of signaling, for the carrying providing the IP that does one's best to connect, along with PDN(PacketDataNetwork, packet data network) establishment of connection and setting up, destroy, for user provides forever online IP transmission service along with the dismounting of the connection of PDN; Dedicated bearer is set up (default bearing cannot meet) to provide certain specific QoS to transmit demand.
Due to the restriction of Radio Resource, eNB(and base station) request of a certain default bearing may be refused; Core net receives default bearing when setting up failure response, local detach(attachment removal) this UE; DRB(DataRadiobearer corresponding to default bearing is set up because UE does not receive, Data Radio Bearer) message, the all EPS of local deexcitation carry context(context), carry out local detach(when only having a default bearing), then attach(attachment is initiated) process, until attach attempts the maximum reaching permission.
Realizing in process of the present invention, inventor finds at least there is following problem in prior art:
In existing LTE system, call access control realizes based on carrying, and call access control fine size, realizes more complicated; For some private network system, business is more single, does not need complicated admission control mechanism.
