Abstract:
1. A method for a base station to obtain radio capability information of a User Equipment (UE) in a Long Term Evolution (LTE) system, comprising: determining, by the base station, whether an initial context setup request message from a Mobility Management Entity (MME) contains an Information Element (IE) of forbidden inter radio access technologies; when it determined that the IE of forbidden inter radio access technologies is contained, writing, by the base station, radio access technology types, which are not included in the IE of forbidden inter radio access technologies, into a query message of UE radio capability information according to the IE of forbidden inter radio access technologies; sending, by the base station, the query message of UE radio capability information to the UE; and sending, by the UE, UE radio capability information of radio access technologies supported by the UE itself to the base station according to the radio access technology types in the query message of UE radio capability information; wherein the query message includes radio access technology type (RAT-TYPE) field, and the writing radio access technology types, which are not included in the IE of forbidden inter radio access technologies, into a query message comprises: deleting the radio access technology types included in the IE of forbidden inter radio access technologies from the list of all radio access technologies supported by protocol to obtain a new radio access technology type list; and writing the radio access technology types in the obtained new radio access technology type list in the RAT-TYPE field of the query message.
