Embodiment 1

[0126] The base station can obtain the MA information in the S1 interface common signaling exchanged with the MA.

[0127] The aforementioned S1 interface public signaling may include but is not limited to one of the following:

[0128] (1) S1 setup response (S1SETUPRESPONSE) message;

[0129] (2) MME configuration update (MMECONFIGURATIONUPDATE) message.

[0130] In this preferred embodiment, the base station obtains the MA information of the MA through the S1 establishment response message when establishing an S1 connection with the MA.

[0131] Figure 5 It is a flowchart of obtaining MA information of the MA through the S1 establishment response message when the base station establishes an S1 connection with the MA according to a preferred embodiment of the present invention. Such as Figure 5 As shown, the process can include the following processing steps:

[0132] Step S502: When the base station establishes an S1 connection with the MA, the MA informs the base station of its own...

Embodiment 2

[0139] The base station can obtain the MA information in the S1 interface dedicated signaling exchanged with the MA.

[0140] The S1 interface dedicated signaling can include but is not limited to one of the following:

[0141] (1) Initial context request (INITIALCONTEXTSETUPREQUEST) message;

[0142] (2) Downlink NAS transmission (DOWNLINKNASTRANSPORT) message;

[0143] (3) S1 handover request (S1HANDOVERREQUEST) message.

[0144] In this preferred embodiment, the base station mainly obtains the MA information of the MA through the initial context request message.

[0146] Step S602: After the SCTP connection for the S1 connection between the base station and the MA is established, the base station sends a...

Embodiment 3

[0154] The base station may obtain the MA information of the MA connected to the opposite base station in the X2 interface public signaling exchanged with the base station.

[0155] The aforementioned X2 interface public signaling may include but is not limited to one of the following:

[0156] (1) X2 Setup Request (X2SETUPREQUEST) message;

[0157] (2) X2 Setup Response (X2SETUPRESPONSE) message;

[0158] (3) eNB configuration update (eNBCONFIGURATIONUPDATE) message;

[0159] (4) eNB configuration update confirmation (eNBCONFIGURATIONUPDATEACKNOWLEDGE) message.

[0160] In this preferred embodiment, when the X2 connection between the base stations is established, the MA information of the MAs connected to each other can be exchanged in the X2 establishment request message and / or the X2 establishment response message.

[0161] Figure 7 It is a flowchart of exchanging the MA information of the MAs connected to each other in the X2 establishment request message and / or the X2 establishment ...

Abstract

The invention discloses an identical anchor point switching determining method and device. The method comprises the steps that a source bases station obtains the MA information of an MA (moving anchor) connected with the source base station and the MA information of an MA connected with a target base station; and the source base station judges whether the switching is X2 switching at the same MA or not according to the MA information of the MA (moving anchor) connected with the source base station and the MA information of the MA connected with the target base station. According to the technical scheme of the invention, the method achieves the judgment of X2 switching at the same MA from the base station side, and enables the subsequent processing to the feasible and flexible.

Description

Technical field [0001] The present invention relates to the field of communication, and in particular to a method and device for judging handover at the same anchor point. Background technique [0002] With the continuous evolution of wireless communication technologies and standards, mobile packet services have undergone tremendous development, and the data throughput capacity of a single terminal has been continuously improved. Taking the Long Term Evolution (LTE) system as an example, it can support data transmission with a maximum downlink rate of 100 Mbps within a 20M bandwidth. In the subsequent enhanced LTE (LTE Advanced) network, the data transmission rate will be further increased, even Reach 1Gbps. [0003] In order to meet the growing demand for data traffic and the geographical unevenness of the business, operators are also adding low-power nodes (LowPowerNode, LPN) or so called in the process of deploying a new generation of communication networks (such as LTE) Small...
