Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] figure 1 It is a flowchart of a method for judging whether to terminate communication between a mobile terminal and a base station in a CDMA system in a preferred embodiment of the present invention. This embodiment includes step S1, step S2 and step S3. Wherein, the mobile terminal includes but is not limited to any mobile terminal capable of accessing a base station, for example, a smart phone, a tablet computer, and the like. The base station includes a signal sending terminal and a signal processing unit; wherein, the signal sending terminal includes but not limited to an antenna, etc., and the signal processing unit includes but not limited to a device for signal processing in the base station, the signal processing unit It can be further divided into multiple devices, such as channel elements, processing devices, and so on.

[0027] It should ...

Abstract

The invention provides a method and a device for judging whether to terminate communication between a mobile terminal and a base station. The method comprises the following steps: acquiring a first time span which starts from the time when a signal processing unit in the base station sends a first signal to the mobile terminal and ends at the time when the signal processing unit in the base station receives a feedback signal fed back by the mobile terminal for the first signal, a second time span required for signal transmission between the signal processing unit and a signal transmission terminal and a third time span required to be delayed when the mobile terminal sends a signal; determining a fourth time span required for signal transmission between the signal transmission terminal and the mobile terminal according to the first time span, the second time span and the third time span; terminating communication between the mobile terminal and the base station when the mobile terminal is positioned in a service prohibition area is judged according to the fourth time span. According to the invention, whether the distance between the mobile terminal and the base station exceeds the allowed service provision range can be judged more accurately.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for judging whether to terminate the communication between a mobile terminal and a base station in a CDMA system. Background technique [0002] In some cases, precise control over the signal range of accessible base stations is required. For example, on some national borders, it is necessary to prevent mobile phones from other countries from accessing local server base stations, but the distance between the two countries may be very close. For example, the two countries divide the national border by a river, but the width of the river is only 100 meters, etc. [0003] In other countries, in order to prevent users from accessing their own base stations, other countries will broadcast a strong narrowband frequency to block their own communication systems. This congestion can also affect basic call access at national borders. [0004] In the prior art, t...
