A capability synchronization method, device and communication system

Abstract

Provided are a capability synchronization method and device and a communication system, which relate to the field of communications and can solve the problems that capability synchronization cannot be conducted between a network device and a user terminal. The method comprises: a user terminal packeting the supported capability information to obtain packet capability information, the packet capability information comprising first packet capability information and second packet capability information; the user terminal reporting a resource request message to a network device, the resource request message comprising the packet capability information, so that the network device selects a service resource according to the packet capability information; the user terminal receiving a first service resource selected according to the first packet capability information which is allocated by the network device; and when the network state changes, the user terminal receiving a second service resource selected according to the second packet capability information which is allocated by the network device. The embodiments of the present invention are used for conducting capability synchronization between the network device and the user terminal.

Description

technical field [0001] The present invention relates to the communication field, in particular to a capability synchronization method, device and communication system. Background technique [0002] With the continuous advancement of mobile communication technology, the mobile communication system has experienced from GSM (global system for mobile communications, Global System for Mobile Communications) to GPRS (general packet radio service, general packet radio service) / EDGE (enhanced data rate for GSM evolution , enhanced data rate GSM evolution technology), and then to the rapid development of UMTS (universal mobile telecommunications system) / LTE (long term evolution, long-term evolution), the development of mobile communication systems also requires the continuous development of user terminals progress. In practical applications, the capabilities supported by different user terminals may be different under various standards. The capabilities supported by the terminal may...
