Problems solved by technology

Currently, the application of the Femto system is to allocate independent LACs, which will introduce location update and handover requests generated by continuous cell reselection in the edge areas. If the Femto system does not support the pool function, it will greatly increase the signaling between MSCs. overhead
At the same time, it will also reduce the call success rate and paging success rate.

Embodiment 1

[0057] This embodiment describes the situation where the macro network moves to a Femto cell.

[0058] Step 101: the mobile phone enters the Femto cell from the macro network, and initiates a location update request;

[0059] Step 102: the Femto gateway receives the location update request and decodes it;

[0060] Step 103: Through decoding, it is found that the location update type is normal location update, and the Femto gateway judges that it is moving from the macro network cell to the Femto cell;

[0061] Step 104: Send to the NNSF module, perform LAC conversion on the location update message, perform the NNSF selection algorithm, and select the corresponding MSC to send;

[0062] Step 105: The Femto gateway saves the corresponding base station information and NRI information of the mobile phone.

Embodiment 2

[0064] This embodiment describes the situation where a Femto cell moves to a Femto cell.

[0065] Step 201: the mobile phone moves from the old Femto cell to the new Femto cell, and initiates a location update request;

[0066] Step 202: the Femto gateway receives the location update request and decodes it;

[0067] Step 203: Through decoding, it is found that the location update type is normal location update, and the Femto gateway judges that it is moving from the old Femto cell to the new Femto cell;

[0068] Step 204: Send a location update acceptance message to the mobile phone, and update the Femto base station information corresponding to the mobile phone, and update the core network node information corresponding to its NRI;

[0069] Step 205: Terminate the location update process of the mobile phone.

Embodiment 3

[0071] This embodiment describes other location update situations

[0072] Step 301: The mobile phone initiates a location update message;

[0073] Step 302: the Femto gateway receives the location update request and decodes it;

[0074] Step 303: Through decoding, it is found that the type of location update is not normal location update, but one of periodic location update or mobile phone power-on or mobile phone power-off;

[0075] Step 304: Send to the NNSF module for LAC conversion;

[0076] Step 305: The Femto gateway encodes the location update request message converted by the LAC and sends it to the core network corresponding to the NRI.

Abstract

The invention provides a method for enabling an Femto gateway to have access to a core network pool and a gateway. The method comprises the steps that location update messages are obtained, and decoding is performed on the location update messages; whether the location update messages need to be sent to a core network is judged according to the location update types; LAC switching is performed on the decoded location update messages needing to be sent to the core network; a corresponding MSC/SGSN in the core network is selected to be sent. The invention further provides a network framework. According to the method for enabling the Femto gateway to have access to the core network pool, the gateway and the network framework, a network level automatic real-time redundancy backup mechanism is supplied in network Pool application under an Femto framework.

Description

technical field [0001] The invention relates to a wireless communication network, in particular to a method for accessing a core network pool by a Femto gateway, a gateway and a network framework. Background technique [0002] In the traditional network architecture, the core network has a tree structure, and one BSC / RNC can only be controlled by one core network node. If the core network node fails, the BSC / RNC managed by it cannot work normally. With the advancement of technology, an MSC Pool technology has emerged in the industry. This technology introduces the concept of "Pool Area", where multiple core network nodes form an area pool. Different from the one-to-one control relationship between RNC / BSC and MSC in the past, each RNC / BSC in the MSC Pool can be controlled by all MSC nodes in the pool, and each MSC node equally serves all RNC / BSC in the pool area. In the area covered by the BSC, end users connected to the RNC / BSC can register with any MSC node in the pool. ...
