Description
Technical field
The present invention relates to mobile communication technology, in particular, the present invention relates to a kind of overloading and between floating radio network controller and service wireless network controller, realize the mutual method of terminal carrier frequency information by the Iur interface in the TD-SCDMA mobile communication system frequently.
Background technology
TD-SCDMA is one of three main standard of the 3G (Third Generation) Moblie that develops rapidly at present, this is a kind ofly to have adopted time division duplex and guaranteed that at up direction all terminal signalings arrive the mobile communication system based on code division multiple access of base station synchronously, are called mobile communication system of time division synchronization code division multiple access again.The TD-SCDMA system carries out standardization by third generation partner program (3GPP) tissue, can be referring to related standards and the technical report of 3GPP to the detailed description of this system.
Fig. 1 has provided the network configuration of TD-SCDMA system.System is made up of user equipment (UE), wireless access network (UTRAN) part and core net (CN) part.Wherein wireless access network by 1 or a plurality of RNS (RNS) form, each RNS comprises that a radio network controller (RNC) and one or more base station (Node B) form.Interface between RNC and the core net is the Iu interface, and the interface between Node B and the RNC is an Iub interface, and the interface that communicates between the RNC is the Iur interface, and the agreement of communicating by letter between above-mentioned interface and the interface thereof all defines in the 3GPP related specifications.
