Embodiment 1

[0096] This embodiment provides a method for releasing the user equipment context on the home base station gateway. This embodiment is based on the application scenario of the home base station. The method in this embodiment includes the following process:

[0097] Step S1102: After receiving the message with the first information element sent by the gateway of the target HNB, the target base station sends a message with the second information element to the source HNB;

[0098] Step S1104: After receiving the target Femtocell's message with the second information element, the source Femtocell triggers the source Femtocell gateway to release the user equipment context message based on the second information element;

[0099] Step S1106: The source Femtocell gateway releases the user equipment context.

[0100] Preferably, the first information element may be a new information element added to an existing message of the system and / or a changed information element on the basis o...

Embodiment 2

[0119] This embodiment provides a method for releasing the user equipment context, which is based on figure 2 In the scenario where the X2 handover operation is performed between HeNB1 and HeNB3, in this embodiment, the following method is proposed for releasing the user equipment context by the home base station gateway HeNBGW1 connected to HeNB1, and the method includes the following process:

[0120] Step S1202: the system performs the X2-based handover operation of the UE according to the existing operation procedure.

[0121] Step S1204: HeNB3 sends a path switching request to the MME.

[0122] Step S1206: User plane data path conversion update.

[0123] Step S1208: the MME sends a path switching request confirmation to the HeNB3, wherein the confirmation message carries the first information element. It should be noted that since HeNB3 is directly connected to MME, the PATH SWITCH REQUESTACK message sent by MME does not carry the first information element, that is, it...

Embodiment 3

[0128] This embodiment provides a solution for releasing the UE context by the home base station gateway HeNB GW1 connected to HeNB1. figure 2 In the scene where the X2 handover operation is performed between HeNB1 and HeNB4, the method includes the following steps:

[0129] Step S1302: the system performs the X2-based handover operation of the UE according to the existing operation procedure.

[0130] Step S1304: HeNB4 sends a path switching request to HeNB GW2.

[0131] It should be noted that since HeNB4 is connected to the home base station gateway HeNB GW2, HeNB GW2 can receive the Path Switch Request message sent by HeNB4, and needs to perform a judgment operation. In order to make this embodiment more clearly describe the entire operation process, here A determination operation that can be applied to HeNB GW2 is given, but it should be understood that the determination operation described here is only used to explain this embodiment, and is not used to limit this embo...

Abstract

The present invention discloses a method, device and system for processing user equipment context. The method includes: a target home base station receiving a message carrying a first information element sent from a peer network element connected to the target home base station, wherein the first information element is The element carries information about whether the source home base station corresponding to the target home base station triggers the peer network element connected to the source home base station to release the user equipment context or whether the source home base station and the target home base station are connected to the same peer network element; the target home base station According to the information, a message carrying the second information element is sent to the source home base station to indicate whether the source home base station triggers the peer network element connected to the source home base station to release the user equipment context. Through the present invention, the accuracy of user equipment context release is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a processing method, device and system for user equipment context. Background technique [0002] A home base station (Home eNB, HeNB for short) is a small, low-power base station deployed in indoor places such as homes and offices. The main role of the home base station is to provide users with higher service rates and reduce the cost of using high-rate services, and at the same time, to make up for the lack of coverage of existing distributed cellular wireless communication systems. The advantages of femtocells are affordable, convenient, low power output, plug and play, etc. [0003] The Femtocell network architecture in the advanced Long Term Evolution (LTE) system launched by the Third Generation Partnership Projects (Third Generation Partnership Projects, 3GPP for short) is as follows: figure 1 As shown, the HeNB completes the connection with the core network element bas...
