RRC connection establishment process is used for setting up RRC and connects, and makes subscriber equipment (User Equipment, UE) connect (RRC_CONNECTED) state from RRC free time (RRC_IDLE) state transitions to RRC, starts high-level signaling or data transmission procedure.This process relates generally to the foundation of Signaling Radio Bearer (SignalRadio Bearer, SRB) 1.
When UE is in RRC_IDLE state, and when high level requests sets up a RRC connection, UE initiates this process.The interacting message of RRC connection establishment process as depicted in figs. 1 and 2.
Initiate RRC connection establishment process time, UE according in system information block (System InformationBlock, SIB) 2 based on the blockage parameter of access grade (AC) and the state of associated timer, determine whether allow access current persistent district.If current area allows access, then UE adopts the configuration indicated in the default configuration and broadcast message that it is stipulated in the agreement that, open T300 timer (maximum time for the response of control UE wait-receiving mode network side), and send RRC connection request (RRC ConnectionRequest) message; Otherwise the rrc layer of UE to the failure of high level instruction RRC connection establishment, and is opened corresponding timer and realized keeping out of the way, guarantee no longer to indicate at timer open period high level to set up RRC and connect.
RRC connection establishment reason unit (RRCconnection establishment cause IE) is carried, the reason that instruction connection establishment is initiated in RRC Connection Request message.The particular content of RRC ConnectionRequest message has definition in 36.331 agreements.
In sum, according to existing protocol, when network congestion, the speech business of connected state UE cannot be realized, high-priority service, urgency traffic have precedence over the object that other business carry out dispatching or accessing.

Provide the concrete example explanation of the embodiment of the present invention below.
Embodiment 1: network side utilizes broadcast or dedicated signaling to indicate this UE to carry out the control information of service access can be such as the current behavior of network current congestion state or indicating user.
Network side judge current or be about to be in network congestion condition time, base station informs to UE by network congestion condition information or to the behavior of user instruction.The mode that network side notice UE carries out the control information of service access can have following several:
Mode one: reuse version 8(R8) system message update process.
At system information block (System Information Block, SIB) 2 or new (new) SIB in introduce the network congestion instruction of 1bit or UE behavior limits instruction, the i.e. only partial service instruction that can access, the concrete business allowing access can be that network notifies further, also can be that default configuration is good.This 1bit IE is optional (optional).
Network side judge current or be about to be in congestion state time, eNB is by page notification UE, then start to transmit in first radio frames in next one amendment cycle and carry congested relevant instruction, amended system information, namely in SIB2 or other SIB, utilize this 1bit information indication network jam state information or the restriction to UE behavior.After UE receives beep-page message, the system information starting to read the renewal of carrying congested relevant instruction in cycle can be revised at the next one, and determine follow-up UE behavior according to this instruction.
Mode two: reuse R10 earthquake and tsunami warning system (Earthquake and Tsunami WarningSystem, ETWS) notification procedure.
In SIB2 or new SIB, introduce 1bit network congestion instruction or UE behavior limit instruction, i.e. the only partial service instruction that can access, and the concrete business allowing access can be that network notifies further, also can be that default configuration is good.This 1bit IE is optional.
Network side judge current or be about to be in network congestion condition time, by paging (Paging), first eNB notifies that UE network congestion condition or UE behavior limit and changes, then UE limits instruction configuration by the network congestion instruction or UE behavior of reading 1bit newly-increased in SIB2 or new SIB, obtains network state or the concrete restriction to UE behavior.
Mode three: dedicated signaling mode.
Can be specifically be used to indicate to the UE transmission being in connection status the control information that this UE carries out service access by RRC signaling, MAC signaling or PDCCH signaling.
Network side utilizes dedicated signaling, notice UE network is current or be about to be in congestion state, or network under congestion state to the restriction of UE behavior, i.e. the only partial service instruction that can access, the concrete business allowing access can be that network notifies further, also can be that default configuration is good.
Further, base station is when notifying UE network congestion instruction, can simultaneously informing business or QoS access or dispatching priority, the priority instruction numbering etc. between the business that allows access or do not allow the type of service that accesses or QoS information, permission access or scheduling can be comprised.Further, base station can notify that UE allows access or do not allow the access control parameter of business or the QoS value accessed simultaneously, such as, access ratio, access barred duration etc.UE accesses or does not allow type of service or the QoS information of access according to the permission that network side notifies, determines whether new business is initiated or request scheduling.
Further, the duration that this congestion state continues can be estimated in base station, base station can duration of informing network congestion state simultaneously when notifying UE network congestion instruction, the timestamp of such as congested beginning and end, or stamp of congested time started and congestion sustains condition timer etc.The congestion state duration that UE notifies according to network side, according to network instruction or default configuration within this duration, determine whether new business is initiated or request scheduling.Or after network judges relieve congestion, eNB notifies that UE gets back to proper network access state, does not access behavior limit UE.
Embodiment 2: under network congestion condition, the initiation of UE business or the method for continuation transmission.
After UE receives the congestion state instruction of network advertisement or UE behavior limits instruction (1bit), this indication information is informed to the application layer of UE by UE rrc layer, judges whether uplink service initiates or whether continue transmission by the application layer of UE according to network advertisement.If network does not notify the type of service allowing to initiate or the type of service not allowing initiation simultaneously, according to default configuration, UE determines whether uplink service initiates or whether continue to transmit, and this default configuration can be that agreement provides.In addition, network side can notify the access parameter (similar MMTEL-voice, MMTEL-video parameter) of different business simultaneously, and by the access parameter of UE application layer according to this different business, whether decision business gets clogged (bar), by ratio that bar falls etc.
Such as, eNB notifies UE network congestion, notify simultaneously UE only voice (voice) business, urgent (emergency) business, high-priority service can access network or continue scheduled transmission, after UE RRC receives this network congestion indication information, this network congestion indication information is given alternately the application layer of UE, the application layer of UE, according to this mutual network congestion indication information, determines follow-up only voice business, emergency business can continue initiation or scheduling.When this network congestion indication information is effective, if there is the triggering demand of new business, first application layer judges type of service, the non-voice business of the type of service if desired initiated, emergency business, then application layer is suspended or stopped the initiation of this new business; If desired the type of service initiated is voice business, emergency business, then application layer specifies according to existing protocol, and the carrying continuing to initiate this new business is set up and transmission.When this network congestion indication information is effective, if the business upstream data of built vertical carrying arrives, first application layer judges type of service, if the non-voice business of type of service, emergency business, then application layer is suspended or stopped issuing of these new business data.
Embodiment 3: under network congestion condition, the initiation of UE business or the method for continuation transmission.
The method is substantially the same manner as Example 2, and difference is: notified to judge whether uplink service initiates or whether continue transmission according to network side by UE rrc layer.
Be specially: UE application layer is when there being service bearer to set up demand, corresponding Non-Access Stratum (NAS) message and type of service message are informed to UE rrc layer simultaneously, UE rrc layer indicates according to network congestion condition, judges whether this business continues to initiate to set up or transmission; Or, when UE RRC receives network congestion instruction, to the congested instruction relevant information of the UE application layer Internet or the network congestion of notice application layer, after UE application layer receives the network congestion relevant information that Access Layer (AS) notifies, follow-up have service bearer to set up demand time, the NAS message of correspondence and type of service message are informed to UE rrc layer simultaneously, and then UERRC layer is according to network congestion condition information, judges whether this business continues to initiate to set up or transmission.
Embodiment 4: under network congestion condition, the sending method of D-SR.
UE application layer, when business is initiated, notifies the traffic type information that UE rrc layer is concrete while sending NAS message.The rrc layer of UE preserves the corresponding relation of each type of service and carrying or the corresponding relation of type of service and logic channel.After UE receives the congestion state instruction of network advertisement or UE behavior limits instruction relevant information, UE rrc layer is by network congestion condition information, whether such as network congested, allow or do not allow to access or transmission type of service or service quality (QoS) information, allow the priority instruction numbering between the business of access or scheduling, access allows the information such as scale parameter, and the corresponding relation of the type of service of preserving and carrying, or the corresponding relation of type of service and logic channel, mutual to UEMAC layer.When UE has up (UL) business to arrive and needs to trigger D-SR, first UE checks network congestion condition information, and according to the type of service of preservation and the corresponding relation of carrying, or the corresponding relation of type of service and logic channel, and the information such as the access priority of data to be transmitted, determine whether continue to report D-SR, request uplink transmission resource.If the service bearer non-network congestion state that the business triggering BSR particularly triggers conventional BSR allows the type of service of transmission or the service priority grade of corresponding non-permitted access, then UE MAC layer cancels BSR and D-SR triggered; If the service bearer that the business triggering BSR particularly triggers conventional BSR is that network congestion condition allows the type of service (such as speech business) of transmission or the corresponding service priority grade allowing access, then UE MAC layer reports D-SR.After network congestion condition is removed, UE MAC carries out the triggering of BSR and D-SR according to Current protocol again and reports, and prerequisite is that UE RRC needs notice UE MAC network congestion condition to remove.
Embodiment 5: under network congestion condition, the sending method of D-SR.
