Problems solved by technology

Usually SeNB is a small base station, which has a small coverage area and is densely deployed in hotspot areas. In the scenario where UE moves in such a large number of densely deployed areas of small base stations, if each SeNB addition / change process requires the participation of core network elements Interaction will lead to a large core network signaling load and cause delays in the SeNB management process
[0019] For the above problems, no effective solution has been proposed

Embodiment 1

[0088] The applicable scenario of this preferred embodiment is that the MeNB adds the first SeNB for the UE. Figure 8 It is a schematic diagram of a scenario where a MeNB adds a first SeNB to a UE according to a preferred embodiment of the present invention. Such as Figure 8 As shown, the SeNB can be connected to the MeNB through the Mobility Anchor, wherein the X2-C interface is connected to the MeNB through the Mobility Anchor, and the X2-U is optionally terminated at the Mobility Anchor. The SeNB is connected to the EPC through the mobility anchor point, specifically, S1-U goes to the S-GW through the mobility anchor point. Figure 9 It is a flow chart of adding the first SeNB for UE by MeNB according to preferred embodiment 1 of the present invention. Such as Figure 9 As shown, the process may include the following processing steps:

[0089]Step S902: During the moving process of the UE, if the UE moves within the range of the SeNB and detects a cell of the SeNB, it...

Embodiment 2

[0097] The applicable scenario of this preferred embodiment is that the MeNB adds the first SeNB for the UE. As above Figure 8 As shown, the SeNB can be connected to the MeNB through the Mobility Anchor, wherein the X2-C interface is connected to the MeNB through the Mobility Anchor, and the X2-U is optionally terminated at the Mobility Anchor. The SeNB is connected to the EPC through the mobility anchor point, specifically, S1-U goes to the S-GW through the mobility anchor point. Figure 10 It is a flow chart of adding the first SeNB for the UE by the MeNB according to the second preferred embodiment of the present invention. Such as Figure 10 As shown, the process may include the following processing steps:

[0098] Step S1002: During the moving process of the UE, if the UE moves within the range of the SeNB and detects a cell of the SeNB, it reports a measurement report to the MeNB, and the MeNB may determine to perform a SeNB addition procedure for the UE according to...

Embodiment 3

[0110] The applicable scenario of this preferred embodiment is that the UE's MeNB remains unchanged and the UE moves between SeNBs. Figure 11 is a schematic diagram of a scenario where the MeNB of the UE remains unchanged and the UE moves between SeNBs according to a preferred embodiment of the present invention. Such as Figure 11 As shown, the UE moves from the coverage area of ​​the source SeNB1 to the coverage area of ​​the target SeNB2. The source SeNB1 can be connected to the MeNB through the mobility anchor, wherein the X2-C interface is connected to the MeNB through the mobility anchor, and the X2-U is optionally terminated at the mobility anchor. The source SeNB1 is connected to the EPC through the mobility anchor point, specifically, S1-U goes to the S-GW through the mobility anchor point. The target SeNB2 can be connected to the MeNB through the mobility anchor, wherein the X2-C interface is connected to the MeNB through the mobility anchor, and X2-U is optionall...

Abstract

The invention discloses a transmission processing method, device and system for user data. The method comprises the steps that: a mobile anchor point sends first GPRS (General Packet Radio Service) tunneling protocol information to an auxiliary base station, wherein the first GPRS tunneling protocol information is GPRS tunneling protocol information which is allocated for the auxiliary base station by the mobile anchor point and is transmitted and borne by an S1; and / or, the mobile anchor point sends second GPRS tunneling protocol information to a main base station, wherein the second GPRS tunneling protocol information is GPRS tunneling protocol information which is allocated for a service gateway by the mobile anchor point and is transmitted and borne by the S1. The transmission processing method, device and system disclosed by the invention solve the technical problems of a signaling load of a core network and a large time delay in the SeNB management process in a dual-link architecture adopted in the prior art.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a user data transmission processing method, device and system. Background technique [0002] With the rapid development of wireless multimedia services, people's demand for high data rate and user experience is increasing, which puts higher requirements on the system capacity and coverage of traditional cellular networks. In a traditional Long Term Evolution (LTE for short) cellular network, a macro base station serves as the only access-side network element to provide access services for user equipment (User Equipment, UE for short). In order to meet users' demands for higher data rates and improve the spectral efficiency of cellular networks, the 3rd Generation Partnership Project (3GPP for short) introduced a low power node (Low power Node, LPN for short) as a macro base station. The supplement provides access services for the UE. LPN has the characteristics of low cost, l...
