Wireless mobile device, and wireless communication station, system and method

Abstract

A wireless communication system for improving the handoff of wireless mobile devices according to geographic information, including: a first station and a wireless mobile device transmitting first geographic information to the first station and receiving from the first station a first scanning-station period, a first threshold velocity, and a first threshold steering angle corresponding to the first geographic information. When the motion speed of the wireless mobile device is greater than the first threshold velocity or the angle at which the wireless mobile device changes its direction of motion is greater than the first threshold steering angle, the wireless mobile device transmits the second geographic information to the first station and receives from the first station a second scanning-station period, a second threshold velocity, and a second threshold steering angle corresponding to the second geographic information.

Description

technical field [0001] The present invention relates to a wireless mobile device, a wireless communication service station, a system and a method for improving the hand-off problem of a wireless mobile device, in particular to a wireless mobile device for improving the hand-off problem of a wireless mobile device based on geographical information, Wireless communication service platform, system and method. Background technique [0002] In the current wireless communication system, a wireless mobile device will scan the service stations in the area where the wireless mobile device is located according to a scanning station period (this is a fixed period) stored in the wireless mobile device in advance, and by scanning The reached service station registers with a system service provider server. For example, when the wireless mobile device scans a first service station, the wireless mobile device registers with the system service provider server through the first service statio...

Problems solved by technology

However, the wireless mobile device still has handover failures

For example, when the first service station cannot provide sufficient signal strength to the wireless mobile device, and the wireless mobile device has not yet registered (handover) to the second service station, handover failure will result

More specifically, since the wireless mobile device will scan the service station according to the scanning station cycle pre-stored in the wireless mobile device, when the wireless mobile device moves away from the first service station at a high speed, it will cause the The wireless mobile device cannot receive sufficient signal strength from the first service station, and because the wireless mobile device does not perform a scan action before the next scan, it has not registered with the second service station, resulting in handover failure

Other situations such as handover delay (when the wireless mobile device changes hands, it needs to register with the platform first, and this process takes time) or the service areas of the first service platform and the second service platform have little overlap, etc. will lead to handover. hand failure

[0005] In addition, since the scanning station period pre-stored in the wireless mobile device is a fixed period, no matter whether the wireless mobile device is close to the service station or whether the mobile device is moving, it will scan the service station at a fixed period, so Firstly, it will cause issues such as higher power consumption or handover failure.

[0006] Therefore, it is necessary to propose a new handover method and a wireless communication system using this method, so that when the wireless mobile device is close to the service station, the scanning period of the wireless mobile device to scan the station is longer or when the wireless mobile device is far away When serving the station, the wireless mobile device scans the station with a short cycle to solve problems such as high power consumption or handover failure
