Embodiment 1

[0248] Embodiment 1 (target system decision-making):

[0249] Step 100: Receive a terminal switching request sent by a source access network node;

[0250] Step 110: Estimate the rate value of the terminal after switching from the source cell to the target cell according to the terminal handover request;

[0251]Step 120: When it is determined that the estimated handover rate value satisfies the preset condition, send a terminal handover request response message to the source access network node, so that the source access network node handovers the terminal from the source cell to the target cell.

[0252] In the implementation of the present invention, the source access network node and the target access network node have various forms, for example, optionally, they may belong to any one or any combination of the following:

[0253] GSM, CDMA system, TDMA system, WCDMA system, Frequency FDMA system, Time Division Synchronized Code Division Multiple Access TD-SCDMA (Time Divi...

Embodiment 2

[0327] Embodiment 2 (target system decision-making):

[0328] Step 1000: Send a terminal switching request to the target access network node;

[0329] Step 1100: Receive the terminal handover request response message sent by the target access network node, and handover the terminal from the source cell to the target cell; wherein, the terminal handover request response message is determined by the target access network node according to the estimated terminal handover request from the terminal to the target cell. It is sent when the rate value after the source cell is handed over to the target cell meets the preset condition.

[0330] In the implementation of the present invention, the source access network node and the target access network node have various forms, for example, optionally, they may belong to any one or any combination of the following:

[0331] GSM, CDMA system, TDMA system, WCDMA system, FDMA system, TD-SCDMA system, LTE system.

[0332] In the implementat...

Embodiment 3

[0352] Embodiment 3 (source system decision-making):

[0353] Step 200: receiving the current load information of the target cell reported by the target access network node;

[0354] Step 210: According to the load information, estimate the rate value of the terminal after switching from the source cell to the target cell;

[0355] Step 220: When it is determined that the estimated rate value satisfies the preset condition, send a terminal switching request to the target access network node;

[0356] Step 230: Handover the terminal from the source cell to the target cell when receiving a terminal handover request response message sent by the target access network node according to the terminal handover request.

[0357] In the implementation of the present invention, the source access network node and the target access network node have various forms, for example, optionally, they may belong to any one or any combination of the following:

[0358] GSM, CDMA system, TDMA syst...

Abstract

The present invention relates to the field of wireless communication technology, and in particular to a switching method and an access network node. The method includes: receiving a terminal switching request (100) sent by a source access network node; and estimating that the terminal switches from the source cell to the terminal according to the terminal switching request. The rate value after the target cell (110); when it is determined that the estimated rate value after handover meets the preset conditions, a terminal handover request response message is sent to the source access network node, so that the source access network node removes the terminal from the source cell. Switch to target cell (120). Therefore, the solution provided by the embodiment of the present invention ensures that the rate value of the terminal meets the preset conditions after switching to the target system. Therefore, the impact on the service quality is avoided, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a switching method, an access network node, and a target access network node. Background technique [0002] At present, with the rapid development of communication technology, various new access technologies emerge in an endless stream. Since the networks corresponding to various access technologies usually have their own suitable coverage and application scenarios, heterogeneous system applications composed of systems using different access technologies emerge. [0003] Due to the characteristics of each system, for example, the LTE (Long Term Evolution, Long Term Evolution) system has the characteristics of high transmission rate and small coverage, and UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System) has the characteristics of low transmission rate and small coverage. Therefore, in practical applications, there a...
