Embodiment Construction

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The method for updating the wireless capability provided by the embodiment of the present invention mainly includes: when the GERAN / UTRAN capability of the UE in the connected state changes, the UE uses the NAS (None Access Stratum Non-Access Stratum) procedure, such as the TAU (Tracking Area Update (location update) process, or ServiceRequest (service request) process to notify the MME that its GERAN / UTRAN capabilities have changed. In the interface message between the eNB and the MME, add the instruction information sent by the MME to the eNB, and notify the eNB to initiate UE wireless capabilities. The inquiry process reports the inquiry result to the MME. The indication information may be implemented by using p...

Abstract

The embodiment of the invention discloses a method for updating a wireless capability, which comprises the following steps of: informing a mobile management entity (MME) that the GERAN / UTRAN capability of user equipment (UE) changes according to a non access layer (NAS) message sent by the UE which is in a connection state, initiating a process for inquiring the wireless capability of the UE according to an instruction for inquiring a user capability sent by the MME, and forwarding a wireless capability message sent by the UE to the MME so that the UE which is in the connection state can timely inform the MME to acquire a new wireless capability of the UE when the GERAN / UTRAN capability of the UE which is in the connection state changes and avoid a failure for Inter-RAT switching. The invention also provides a device for updating the wireless capability.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a wireless capability update technology. Background technique [0002] LTE (Long Term Evolved, long-term evolution network) is a mobile communication network actively researched by various manufacturers in the 3GPP (Third Generation Partnership Project) organization. It is a UMTS (Universal Mobile Telecommunication System) Evolved network. The purpose of LTE is to provide a low-cost network that can reduce delay, increase user data rate, increase system capacity and coverage, use packet domain services, and carry IP data packets. [0003] In the prior art, when the wireless capability of the UE (User Equipment) in the LTE network changes, the method for the UE to notify the MME (Mobility Management Entity) to update the wireless capability includes: [0004] If the UE is in the idle state, when the UE's GERAN (Global System for Mobilecommunications / Enhanced Data rate...
