Description

Method for acquiring capability information and i equipment

The present application claims priority to Chinese Patent Application No. 201110231529.0, entitled "Method and Apparatus for Capability Information Acquisition", filed on August 12, 2011, the entire contents of which is incorporated herein by reference. . Technical field

Embodiments of the present invention relate to the field of wireless communications and, more particularly, to methods and apparatus for acquiring capability information. Background technique

In the wireless communication system, the number of UEs in the smart grid and other machine-to-machine applications is the same and the types of UEs are the same, so the capability information of the UEs is consistent. The capability information includes wireless capability information and network capability information. Most of the M2M UEs are single-mode UEs with a single function.

Taking the Long Term Evolution (LTE) communication system as an example, UE radio capability information and network capability information need to be radio resource control (Radio Resource Control, RRC) signaling and non-connection when the UE accesses. The Non-Access Stratum (NAS) signaling is transmitted to the evolved base station (eNB, evolved NodeBase) and the Mobility Management Entity (MME). The UE radio capability information is used when the eNB establishes a data radio bearer (Data Radio Bearer) and performs related radio side configuration. The UE network capability information stores NAS encryption and integrity protection parameters supported by the UE and the core network ( Core Network, the cartridge is called CN) related capability information. Currently, the UE wireless capability information is greater than 50 bytes, and the network capability information is currently 7 bytes.

Normally, after the UE registers in the network, its capability information is stored in the MME, in the ECM-IDLE (Evolved Packet Switching Connection Management-Idle) state to ECM-CONNECTED ( During the transition of the evolved packet connection management-connection state, the MME carries the capability information of the UE to the eNB in an INITIAL CONTEXT SETUP REQUEST message. When the MME does not carry the UE in the INITIAL CONTEXT SETUP REQUEST message For the line capability information, the eNB needs to trigger RRC signaling to query the UE. When the MME is in the Attach or when the UE's wireless capability information stored on the MME is marked as invalid, for example, the Track Area Update (TAU) of the Random Access Techonology (RAT) , will not carry this parameter.

The network capability information of the UE is delivered to the MME through an Attach Request or a TAU Request. When the UEi contends for the RAT of the RAT, the UE network capability information needs to be updated.

When a large number of UEs of the same service M2M access the network at the same time, in particular, the eNB needs to repeatedly perform the UE capability information query, and the MME also repeatedly obtains the network capability information of the UE of the same type from the NAS message, resulting in waste of air interface signaling resources. .

In addition, each UE's wireless capability information is greater than 50 bytes, which also occupies a certain air interface signaling resource.

Summary of the invention
