Service data transmission method and system, and device
First Claim
1. A service data transmission method, comprising:
- receiving, by a user terminal, a request message sent by an access network (AN) entity of a first network, wherein the request message is used to request the user terminal to establish a radio bearer with an AN entity of a second network corresponding to a target cell and wherein the request message comprises at least one of the following;
an identifier of the radio bearer, a quality of service parameter of the radio bearer, traffic flow template information, an indication message, and information about the target cell, the indication message being used for indicating that the radio bearer is to be established in the second network;
establishing, by the user terminal, the radio bearer with the AN entity of the second network; and
transmitting, by the user terminal, service data to the AN entity of the first network by using the AN entity of the second network, wherein the service data is data corresponding to a service identified by the traffic flow template information.

Abstract
Embodiments of the present invention disclose a service data transmission method. An AN entity of a first network sends a first request message to an AN entity of a second network corresponding to a target cell in which a UE is located, so as to request the AN entity of the second network to establish a radio bearer for the UE. The AN entity of the first network sends a second request message to the UE, so as to request the UE to establish the radio bearer with the AN entity of the second network. After the AN entity of the second network has established the radio bearer with the UE, the AN entity of the first network transmits service data to the UE by using the AN entity of the second network.

6. An access node (AN) entity comprising:
-
a processor; and a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions for; sending a first request message to an AN entity of a second network corresponding to a target cell in which a user terminal is to be located, so as to request the AN entity of the second network to establish a radio bearer for the user terminal, wherein the first request message comprises an identifier of the user terminal and a quality of service parameter of the radio bearer; sending a second request message to the user terminal, so as to request the user terminal to establish the radio bearer with the AN entity of the second network, wherein the second request message comprises at least one of the following;
an identifier of the radio bearer, the quality of service parameter of the radio bearer, traffic flow template information, an indication message, and information about the target cell, wherein the indication message is used for indicating that the radio bearer is to be established in the second network; andafter the AN entity of the second network has established the radio bearer with the user terminal, transmitting service data to the user terminal by using the AN entity of the second network, wherein the service data is data corresponding to a service identified by the traffic flow template information. - View Dependent Claims (7, 8, 9, 10, 11, 12)
