Description

Data transmission method, device and system

The present application claims priority to Chinese Patent Application No. 201510502432.7, entitled "A Data Transmission Method, Apparatus and System", filed on August 14, 2015, the entire contents of which is incorporated herein by reference. In the application.

Technical field

The present invention relates to the field of communications technologies, and in particular, to a data transmission method, device, and system.

Background technique

The Evolved Packet System (EPS) is a system that supports multiple access technologies and multiple inter-access mobility. In a multiple access scenario, the terminal may be under common coverage of multiple 3rd Generation Partnership Projects (3GPPs) and/or non-3GPP access networks. These access networks may use different access technologies, may belong to different operators, or may provide access to different core networks. The Universal Mobile Telecommunications System (UMTS)/Long Term Evolution (LTE) and Wireless Local Area Networks (WLAN) coexistence scenarios are shown in Figure 1. The UMTS/LTE base station (UMTS) Within the coverage of the Node B, eNB in LTE, there are multiple WLAN access points (Access Points, APs), wherein the coverage of the access point is smaller than the coverage of the base station.

Based on the network implementation of the existing WLAN, multiple APs are generally controlled by an Access Controller (AC). When LTE and WLAN are aggregated, the eNB may only have a physical interface (Xw) with the AC. When the terminal moves between APs under the same AC jurisdiction, based on the mobility of the current WLAN, the terminal may not interact with the network, that is, the mobility within the AC range is transparent to the eNB. When the terminal moves across the AC, it needs to report to the network, and the target AC is determined by the network. Further, for network implementation and configuration flexibility, the network may configure an AP group (AP group) to the terminal, and the terminal does not need to interact with the network when moving within the AP group.

A terminal that performs LTE-WLAN aggregation is generally indoors, that is, the terminal is in a static state or has a low moving speed. In this scenario, if all APs under a certain AC jurisdiction are configured as an AP group to the terminal, A number of APs are deployed on the AC in the cell. Some APs are useless for the terminal. If these APs are configured to the terminal through signaling, for example, by configuring the basic service set identifier (BSSID). ), the length of 48 bits (bits), will increase the system signaling overhead.
