Problems solved by technology

[0028] The present invention provides a control method and equipment for lossless handover of a mobile station in a WiMAX system, so as to solve the problem in the prior art process that when the handover request or the handover instruction is not sent successfully, the remaining data cannot be transferred from the pre-handover service device to the post-handover service device transmission, resulting in data loss during the switching process

Embodiment Construction

[0072] Since the air interface connection between the mobile station and the network side is susceptible to external interference, the mobile station does not completely send the handover request or handover instruction due to interference or its own reasons, or when the handover request or handover instruction does not reach the current serving device, the current serving device does not know how to move. The target service device of the station cannot send a switch confirmation and a data channel establishment request to the current service device, so that the remaining data cannot be transferred from the pre-switch service device to the post-switch service device, resulting in data loss during the switch process.

[0073] In order to avoid data loss caused by failure to send a handover request or a handover instruction, the present invention optimizes the existing handover process. After the handover of the mobile station is completed, the target service equipment sends a han...

Abstract

The invention is designed for use in solving the issue, existed in current-used technology, that is when the switch request or switch indication is not successfully transmitted, the residual data cannot be transmitted between the service device before switching and the service device after switching so as to cause the loss of data. The invention optimizes the currently-used switch process, and after the destination service device is successfully switched in the mobile station, it sends a switch confirmation to the current service device to trigger the data channel establishing request of current service device in order to ensure the returning process of residual data. The switch control module of the communication device provided by the invention comprises: a sub-module for storing the switch information, a sub-module for confirming the successful switch and a sub-module for triggering the switch confirmation message.

Description

technical field [0001] The invention relates to a WiMAX system, in particular to a control method and equipment for lossless switching of a mobile station in the WiMAX system. Background technique [0002] WiMAX (Worldwide Interoperability for Microwave Access) is an emerging wireless communication technology that can provide high-speed Internet-oriented connections. Currently, there are two structural models for the access-level equipment of the WiMAX system. [0003] As shown in Figure 1, the first architecture of access-level communication equipment in a WiMAX system includes a base station and a gateway. The base station and the mobile station are connected wirelessly through the air interface, and the base station and the gateway, and between the gateway and the gateway are wired connections. The gateway is connected to the data service network, and the mobile station accesses the data network through the base station and the gateway. The gateway directly connected to ...
