Abstract

The invention is applicable to the technical field of communication and provides an LTE (long term evolution) single-card dual-standby multimode terminal and a PS (packet switching) service switching method thereof. The method comprises the following steps that: the LTE single-card dual-standby multimode terminal reports to a switch source system that the single-card dual-standby ability is available through a measurement report in a switch preparation stage; before a downlink channel between the LTE single-card dual-standby multimode terminal and a switch target system is established, the LTE single-card dual-standby multimode terminal receives downlink data from a base station of the switch source system; after the downlink channel between the LTE single-card dual-standby multimode terminal and the switch target system is established and the original data path of the switch source system is removed, the LTE single-card dual-standby multimode terminal finishes the PS service switch between an LTE system and a 2G/3G system; and the LTE single-card dual-standby multimode terminal closes a service channel of the switch source system and receives a downlink data stream from the switch target system. Through the invention, the switch delay of data service is reduced, and the switch interruption of the data service is avoided; and moreover, a network element does not need to establish a transfer channel when in switching, thus the efficiency of network resources is improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to an LTE single-card dual-standby multi-mode terminal and a PS service switching method thereof. Background technique [0002] Long Term Evolution (LTE) is the largest new technology research and development project launched by the 3rd Generation Partnership Project (3GPP) in the past two years. It can be regarded as a "quasi-4G" technology. It improves and Enhanced 3G air access technology, using Orthogonal Frequency Division Multiplexing (OFDM) and multi-user equipment Multiple Input Multiple Output (MIMO) as the basic technology for its wireless network evolution. [0003] LTE single-card dual-standby multi-mode terminals, such as LTE+2G / 3G single-card dual-standby multi-mode terminals reside in two communication subsystems at the same time: circuit switched domain (Circuit Switched Domain, CS domain) resides in 2G / 3G In the system, the packet switched domain ...
