Problems solved by technology

[0004] At present, it is generally possible to limit the mobile range of the user in the call state by adjusting the coverage of the system. However, due to the complexity of the wireless environment and the particularity of the geographical environment, it is impossible to accurately control the coverage of the system signal on the boundary line, so It is impossible to completely limit the range of user movement through the coverage of control signals

Embodiment 1

[0023] A method for limiting the range of movement of a user in a call state is mainly implemented based on the active detection of RTD by the BTS. In this method, an RTD update threshold and an RTD predetermined threshold are set in each sector of the BTS in the border area in advance. Wherein the RTD update threshold value of setting can control the precision of mobile terminal movement limitation, when the RTD update threshold value of setting is smaller, RTD update is more frequent, so the limitation to the mobile terminal's mobile range is more accurate; The set RTD predetermined threshold value is determined according to the distance from the BTS to the restricted boundary area of ​​the mobile communication system. When the mobile terminal is in a conversation state, the method executes as follows: figure 2 The steps shown are:

[0024] Step 201: the BTS detects the RTD change value between itself and the mobile terminal in the talking state;

[0025] In this step, the...

Abstract

The invention discloses a method for limiting a user moving range under a call state, and relates to a cellular mobile communication system. In the method, a base station sender deploys an RTD predetermined threshold value for each sector; the base station sender keeping communication with a mobile terminal in the call state periodically sends a communication round trip delay RTD value between the base station sender and the mobile terminal to a base station controller; the base station controller judges the received RTD value, and if the RTD value is more than the RTD predetermined threshold value at the sector where the terminal is positioned, the terminal is beyond a limited boundary zone of the mobile communication system, and the base station controller releases the call service of the terminal. When the system coverage is beyond the limited boundary zone of the mobile communication system, the user moving range under the call state is precisely limited, and the method is particularly suitable for a CDMA system so as to meet the demands of operators.

Description

technical field [0001] The invention relates to a cellular mobile communication system, in particular to a method for limiting the range of movement of a user in a talking state. Background technique [0002] CDMA2000 (Code-Division Multiple Access) network is a typical cellular mobile communication system, which is the third generation mobile communication system (3G) technology developed on the basis of IS-95 CDMA system. With the rapid development of CDMA technology At present, the CDMA2000 system supports a variety of rich mobile communication services such as voice, data, short message and fax. [0003] In a cellular mobile communication system, users use mobile terminals to access network services, where the mobile terminals can be cellular phones, vehicle-mounted mobile terminals, wireless network cards for portable computers, and wireless fixed stations. After the user terminal accesses the system network, it can use the network service within the signal coverage of...
