Method for reporting and obtaining user equipment multi-carrier frequency ability

Abstract

A method for reporting multicarrier frequency ability of user device includes expanding message content of user device ability and adding multicarrier frequency ability parameter of user device in said message , transmitting expanded ability message to radio network controller by user device , carrying user device multicarrier frequency ability in transmitted message . A method for obtaining multicarrier frequency ability of user device is also disclosed .

Description

technical field [0001] The present invention relates to code division multiple access communication technology, more specifically, the present invention relates to a kind of time division synchronous code division multiple access (TD-SCDMA, Time Division-Synchronization Code Division Multiple Access) multi-carrier frequency system reports, obtains user equipment Multi-carrier frequency capability and radio resource allocation method. Background technique [0002] At present, mobile communication has been developed to the third generation of mobile communication (3G, Third Generation). TD-SCDMA is one of the three main standards of the third generation mobile communication approved by the International Telecommunication Union (ITU, International Telecommunication Union) in May 2000 and by 3GPP in March 2001. As a 3G standard of time-division multiplexing, TD-SCDMA is regarded as a time-division multiplexing technical solution with a low chip rate (1.28MCps, 1.28 megachips / se...

Problems solved by technology

[0013] First of all, the UE capability message does not carry multi-carrier frequency capability information, and the network side cannot correctly allocate radio resources to the UE after receiving the message. For example, in the above technical solution, when the UE initially accesses, it sends The first message (RRC connection request message) does not indicate whether the UE supports multiple carrier frequencies, and the network side cannot judge whether the UE can be assigned to the auxiliary carrier frequency;

[0014] Secondly, there is no information indicating whether the UE supports multiple carrier frequencies in the subsequent UE capability information message, and the network side cannot judge whether the UE can support multiple carrier frequencies, which affects the radio resource allocation strategy during the handover process of the network side;

[0015] Thirdly, when a UE migrates across systems or across RNCs, there is no information indicating whether the UE supports multiple carrier frequencies in the Container from the SRNC to the TRNC, and the network side cannot judge whether the UE supports multiple carrier frequencies, which affects the network's focus on wireless resources during the positioning process. allocation strategy
