Technical field
The present invention relates to the resource management techniques of mobile communication system, particularly relate to the method for base station acquisition subscriber equipment (UE) ability information in wireless network Long Term Evolution LTE (the Long Term Evolution) network.
Background technology
The LTE network is the network of a flattening.Fig. 1 is the LTE network structure, and as shown in Figure 1, (Evolved Node Base, eNB) (Evolved Packet Core EPC) forms this network with the evolution packet switching center by E-UTRAN (Evolved UTRAN) base station.E-UTRAN comprises the set of the eNB that links to each other by the S1 interface with EPC, links to each other by X2 interface between the eNB, and each eNB comprises a plurality of sub-districts.
According to 36.300 agreements, the UE ability information is stored in MME.Set up in the request message at initial context, the UE ability is dealt into the base station from MME, if the base station needs more ability information, then the UE ability acquisition process by Radio Resource control (RRC) is from UE acquisition capability information.In this process, the base station is meeting specifies radio access technology (RAT) information in UE capability query (UECapabilityEnquiry) message that UE sends, in case receive UE ability information (UECapabilityInformation) message of UE, then the base station can send UE ability information indication (UE CAPABILITYINFO INDICATION) to mobile management entity (MME), up-to-date UE ability is passed to MME, and MME can keep these information up to the UE attachment removal or adhere to again.
According to existing protocol, under situation about not switching, the base station will seek out the UE ability, except the UE ability acquisition process that uses RRC, can only set up request message by the initial context that MME sends.
But, at some situation UE is that not need to create UE contextual when entering connected state, for example, under idle (IDLE) state, when UE carries out tracing section updating (TAU) process, if the UE indication does not need to create Data-carrying, do not need to set up the UE context yet, the thresholding that is " active flag " in the TAUrequest message that sends of UE is " false ", and in such cases, MME will can not set up the UE context.Like this, the base station can't obtain the UE ability from MME again.The schematic flow sheet of TAU process may further comprise the steps as shown in Figure 2 under the above-mentioned situation:
Step 1, UE initiate the RRC connection request.
Step 2, eNodeB send the RRC connection to UE and set up message.
Step 3, UE send the RRC connection setup complete message to eNodeB, wherein carry Non-Access Stratum (NAS) message (TAU Request), " Active the flag "=false in this TAU Request message.
" Active flag " in TAU Request message is false, illustrates that then MME need not set up contextual information and set up corresponding carrying for UE in subsequent process.
Step 4, eNodeB send initial UE message to MME, wherein carry NAS message (TAU Request).
Step 5, UE and MME can carry out authentication and security process if necessary.
Step 6, MME send descending Non-Access Stratum message transfer (DOWNLINK NAS TRANSPORT to eNodeB, wherein comprise TAU Accept), distribute global unique temporary identity (GUTI) if MME is UE, then will carry this whole world unique temporary identity information among this TAU Accept.
Step 7, eNodeB send descending NAS message (TAU Accept) to UE.
If comprise GUTI in the step 8 TAU Accept message, then UE sends up NAS message (TAU Complete) to eNodeB, and MME has received this GUTI with notice.
Step 9, eNodeB send up NAS message (TAU Complete) to MME.
If " Active the flag "=false in the step 10 TAU Request message, and TAU initiates under the IDLE state, and then MME can discharge the UE context.
Step 11, eNodeB send RRC to UE and connect release (RRCConnectionRelease) message.
Step 12, UE send UE context Release complete to eNodeB.
In said process, in order to carry out load balancing, connect when discharging at RRC, the base station need dispose alien frequencies/RAT dedicated priority under redirection information and the idle pulley for UE, otherwise, can't realize load balancing.Being specially collocation method is, redirected beared information (RedirectedCarrierInfo) in the RRC connection release message and idle pulley move control information (IdleModeMobilityControlInfo) and be respectively UE and indicated alien frequencies/RAT special priority information under redirected carrier information and the idle pulley.Correspondingly, UE will be redirected to the carrier wave of the indicated E-UTRA of RedirectedCarrierInfo or other access technologies, and use the carrier wave priority of IdleModeMobilityControlInfo indication under idle pulley.
And when being information aspect UE configuration is redirected in the base station, need carry out according to the ability information of UE in order to ensure the accuracy of configuration, otherwise can on eating dishes without rice or wine, transmit invalid control information, and UE need judging whether the carrier information that disposes is supported.
At present, can not obtain the UE ability information in the contextual TAU process of UE above-mentioned foundation in order to make the base station, the UE ability acquisition process of RRC need be triggered in the base station, so, will cause the waste of transfer resource of eating dishes without rice or wine, and increase processing delay.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of base station to obtain the method for UE ability information, and this method can be carried out TAU in the IDLE attitude at UE, and when not needing to set up the UE context among this TAU, the base station can obtain capability information of user facility by quick, and can save interface-free resources.
In order to achieve the above object, the technical scheme of the present invention's proposition is:
A kind of base station obtains the method for UE ability, may further comprise the steps:
Carry out in the process of tracing section updating TAU at the user equipment (UE) that is in Idle state, if mobile management entity MME does not need to set up context for this UE, then this MME utilizes this message that the ability information of this UE is notified to described base station when sending descending Non-Access Stratum message transfer to the base station.
