Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] Such as figure 1 as shown, figure 1 It is a system architecture diagram of a specific application scenario of the embodiment of the present invention; the SGW and the S4 SGSN transmit data for end users through the established user plane bearer A. In the prior art, if a terminal UE activates ISR and establishes a non-DT (Direct Tunnel, direct user plane tunnel) user plane bearer A, when the terminal UE enters the idle state, the connection between the S4SGS...

Abstract

The embodiment of the invention discloses a method, a system and a service gateway for data transmission, which are used for solving the problems of low switching efficiency and speed between a terminal and a network in the prior art. The method, the system and the service gateway for data transmission disclosed in the embodiment of the invention are suitable for a terminal which activates ISR (Idle-mode Signaling Reduction) and is located in the control range of an S4SGSN (S4 Serving GPRS Support Node). When the terminal receives downlink data sent to the terminal, the downlink data transmission can be quickly realized by utilizing the retained user interface loading, therefore, the time delay caused by reestablishment of the user interface loading in the prior art is avoided; the efficiency and the speed of the downlink data transmission are enhanced; and further the user experience is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a data transmission method, system and service gateway. Background technique [0002] When the EPS (Evolved Packet System, Evolved Packet System) network and the G / U (GPRS / UMTS, General Packet Radio Service / Universal MobileTelecommunication System, General Packet Radio Service / Universal MobileTelecommunication System) network are co-constructed, terminals in different RAT (Radio Access Technology, wireless access technology) down and back migration generates a lot of signaling. In order to reduce the resource occupation of the wireless side and the signaling load of the network side as much as possible, the prior art implements signaling saving through ISR (Idle-mode Signaling Reduction, signaling saving in idle state). [0003] After the terminal activates the ISR between the LTE (Long Time Evolution, long-term evolution) network and the G / U network, the user plane in idle mode termin...
