Problems solved by technology

[0003] When user terminals support more and more frequency bands and carrier aggregation combinations, the sum of the above three types of information will inevitably exceed the standard limit of maxBandComb-r10 stipulated by 3GPP, and even exceed the standard limit of maxBandComb-r10+maxBandComb-r11
Carrier aggregation combinations that exceed the standard limit cannot be successfully reported, so some useful key frequency band combination information will be missed during the reporting process

Abstract

The present invention provides a carrier aggregation capability updating method, a carrier aggregation capability updating apparatus and a user terminal. The carrier aggregation capability updating method includes the following steps that: the carrier aggregation capacity pool of a user terminal is generated through the configuration file of the SIM card of the user terminal; the service cell information and neighboring cell information of a network where the user terminal is currently located are detected, so that the network band coverage information of the user terminal can be obtained; and the carrier aggregation capacity pool of the user terminal is updated according to the obtained network band coverage information. Thus, with the carrier aggregation capability updating method adopted, the dynamic maintenance of the carrier aggregation capacity pool of the user terminal is realized, a carrier aggregation combination corresponding to the local network coverage band is preferentially reported; the omission of key band combination information during a reporting process due to protocol and standard restrictions can be avoided, and the matching degree of the reported carrier aggregation capability information and the local network can be improved, and the use experience of the user terminal is optimized.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a carrier aggregation capability updating method, device and user terminal. Background technique [0002] UE (User Equipment, user terminal) is an important concept in mobile communication. After the UE successfully establishes an RRC (Radio Resource Control, radio resource control) connection, the UE will ) protocol stipulates that UECapabilityInformation is filled in the order of priority of "non-carrier aggregation combination information", "2DL+1UL CA (Carrier Aggregation, carrier aggregation) combination information of all frequency bands" and "other carrier aggregation combination information of all frequency bands", and Report to eNodeB (Evolved Node B, evolved Node B, the name of the base station in LTE). [0003] When user terminals support more and more frequency bands and carrier aggregation combinations, the sum of the above three types of infor...
