Embodiment 3

[0141] The newly defined PDCP PDU used to encapsulate CS domain service data in Embodiment 3 and Embodiment 4 can be encapsulated and decapsulated by the PDCP entity in the existing Uu interface protocol stack, which affects the current function of the existing protocol stack smaller.

[0142] In the third and fourth embodiments above, the data frame encapsulating circuit domain service data is a newly defined PDCP PDU. The embodiment of the present invention proposes another data frame, which is called Circuit Service Convergence Protocol (CSCP, Circuit Service Convergence Protocol) data frame, and a new protocol entity can be added to the existing Uu interface, named CSCP entity, which is responsible for encapsulation and decapsulation of CSCP data frame. see Figure 16 , Figure 16 It is a schematic diagram of the position of the CSCP entity in the Uu interface proposed by the embodiment of the present invention. exist Figure 16 Among them, the control SAP (Service Acc...

Abstract

A method for bearing CS-domain service data over radio bearer is disclosed. The method includes: letting CS-domain service data be borne over a radio high-speed packet data access channel according to a channel mapping relation between CS-domain service data and the radio high-speed packet data access channel. An apparatus and a system are also provided herein.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method, device and system for wireless bearing of circuit domain service data. Background technique [0002] The existing wireless communication system network includes three parts: wireless terminal, access network and core network. Among them, the core network part includes two large functional domains, called circuit (CS) domain and packet (PS) domain, which are responsible for business logic processing, mobility management, authentication and encryption, and other functions. Wireless access processing. [0003] Taking the Universal Radio Telecommunications System (UMTS) system as an example, the UMTS Terrestrial Radio Access Network (UTRAN) is one of typical access network types, including a Radio Network Controller (RNC) and a Base Station (Node B). The UE is connected to the UTRAN through the Uu interface, and the UE interacts with network equipment through...
