Problems solved by technology

[0048] However, in the network deployment mode where the user plane and the control plane are separated, there is currently no signaling process that can support bearer switching on the user plane and part of the control plane bearer switching, and it is difficult to realize the corresponding bearer switching. In addition, there is no The eNB bearer management process under the network deployment mode separated from the control plane

Embodiment 1

[0092] Such as Figure 12 As shown, the bearer management method provided by the embodiment of the present invention includes:

[0093] Step S1201, when the macro base station determines that the user plane bearer needs to be switched to the small base station, it sends a user plane bearer transfer request to the small base station, and the user plane bearer transfer request carries information about the user plane bearer to be transferred by the user and the user's current status. The underlying configuration information in the macro base station;

[0094] Step S1202, the small base station and the macro base station transfer the user plane bearer according to the user plane bearer transfer request.

[0095] Usually, when it is determined that the user enters the area covered by the macro base station and the small base station, the macro base station can determine that the user plane bearer of the user needs to be handed over to the small base station.

[0096] In step S12...

Embodiment 2

[0148] When the small base station bears the user plane bearer of all or part of the users, if the core network needs to modify the service, such as adding, modifying or deleting the E-RAB bearer, as follows: Figure 14 As shown, follow the steps below:

[0149] Step S1401, the macro base station receives a message from the core network for adding, modifying or deleting an E-RAB bearer;

[0150] Step S1402, the macro base station sends a bearer addition request message, a bearer modification request message or a bearer deletion request message to the small base station, so that the small base station performs user plane bearer update according to the bearer addition request message, bearer modification request message or bearer deletion request message.

[0151] Wherein, the small base station performs user plane bearer update according to the bearer addition request message, bearer modification request message or bearer deletion request message, specifically including:

[01...

Embodiment 3

[0174]When the user leaves the area covered by the macro base station and the small base station, usually the user plane bearer of the user needs to be handed over from the small base station to the macro base station. Figure 16 As shown, the bearer management method provided by the embodiment of the present invention further includes the following steps to switch the user plane bearer needs from the small base station to the macro base station:

[0175] Step S1601, when the macro base station determines that the user plane bearer of the user needs to be handed over from the small base station to itself, accept the user plane bearer of the user;

[0176] Step S1602, the macro base station notifies the small base station to terminate user plane data transmission and delete the SRB;

[0177] Step S1603, the macro base station sends a user plane handover signaling to the user, and receives a user plane handover completion message returned after the user performs the user plane h...

Abstract

The invention discloses a load managing method, device and system and relates to the communication technology. When a macro base station determines that user plane load of a user needs to be switched to a small base station, the macro base station transmits a user plane load transfer request carrying the information of the user plane load requiring transfer and the bottom configuration information of the user in the macro base station, the macro base station and the small base station can partially transfer the user plane load according to the user plane load transfer request, and accordingly load switching under the network deployment with the user plane being separated from a control plane.

Description

technical field [0001] The present invention relates to communication technology, in particular to a bearer management method, device and system. Background technique [0002] The network architecture of E-UTRAN (Evolved Universal Terrestrial Radio Access Network, Evolved Universal Terrestrial Radio Access Network) is as follows: figure 1 As shown, E-UTRAN consists of eNBs (base stations). The MME (Mobility Management Entity, mobility management entity) is connected to the eNB through the S1-MME interface; the eNB completes the access network function, and communicates with the UE (User Equipment, user equipment) through the air interface. For each UE attached to the network, there is an MME providing services for it, and the MME is called the serving MME of the UE. The S1-MME interface provides control plane services for the UE, including mobility management and bearer management functions. S-GW (Serving Gateway, Serving Gateway) is connected to the eNB through the S1-U ...
