Problems solved by technology

However, undesirably, this gives an unnecessary load to the BS
Also, the call set-up by the user of the requesting MS will wait for it to take a longer time for voicemail traffic to forward incoming callers to the power-off MS than when the BS recognizes the MS's power-off state.

Embodiment Construction

[0018] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described since they would obscure the invention in unnecessary detail.

[0019] For example, an embodiment of the present invention is applied to such a digital mobile communication system. Such systems employ IS-95, IS-634 and IS-41 standards. In particular, the present invention can also be applied to 3G mobile communication systems such as CDMA 2000 (Code Division Multiple Access 2000) and UMTS (Universal Mobile Telecommunications System) mobile communication systems, which not only transmit voice data but also provide high-speed data communication. The 3G mobile communication system provides high-quality voice service, moving image service, and Internet search service.

[0020] FIG. 1 shows an example of a mobile communication system to which an embodiment of the present inv...

Abstract

A power control method for a mobile terminal is disclosed. At a power-off request of a mobile station user, the mobile station attempts to send a power-down registration request to a base station for as many times as set in a maximum attempt sequence. Upon failure to receive a response from the base station even after the attempts to send the power-down registration request for as many times as set in the maximum attempt sequence, the mobile station reattempts the power-down registration request operation for as many times as set in a predetermined retry number. Upon receipt of a response from the base station during the reattempts, the mobile station performs power-off of the mobile station. Further, the mobile station performs a call processing process upon receipt of an incoming call during the reattempts.

Description

technical field [0001] The present invention generally relates to mobile communication systems, and more particularly to a method for controlling power-off of a mobile station. Background technique [0002] Unlike the Public Switched Telephone Network (PSTN), the Public Land Mobile Network (PLMN) controls the connection between a Mobile Station (MS) and a Base Station (BS) in a radio environment. [0003] The third-generation IS-95 mobile communication system capable of transmitting voice and high-speed data can provide high-quality voice services, moving image services, and Internet search services. In such a mobile communication system, a radio communication link existing between an MS and a BS is divided into a forward link transmitted from the BS to the MS and a reverse link transmitted from the MS to the BS. For the exchange of signaling data between the BS and the MS before voice call setup, the paging channel is used as the forward channel and the access channel as t...
