Abstract
A method and device are provided for of supporting a plurality of mobile station operation modes in a wireless communication system by user control. Presently, communication protocols exist for supporting end user equipment which operates in a single mode of operation. However, it is desirable to combine protocols from various technologies to form end user equipment which operates in multiple modes of operation. Thereby, the present method allows the mobile station to operate in a multi-mode environment where a user can invoke a certain mode.
Claims13
A method for controlling a plurality of mobile station operation modes in a wireless communication system, comprising the steps of:
- (a) combining a plurality of protocols which support operating a mobile station in multiple modes, the multiple modes including one or more of packet modes, voice modes and dual packet/voice modes;
- and
- (b) selecting the mobile station to operate in one of said multiple modes;
- wherein said mobile station operation mode selected at said step (b) is a dual packet/voice mode for D-AMPS and CDPD modes.
A method for controlling a plurality of mobile station operation modes in a wireless communication system, comprising the steps of:
- (a) combining a plurality of protocols which support operating a mobile station in multiple modes, the multiple modes including a packet data mode and a voice mode;
- (b) monitoring a digital control channel (DCCH) associated with the voice mode;
- (c) selecting the mobile station to operate in one of said multiple modes;
- and
- (d) if the packet data mode is selected in step (c), switching the mobile station to operate in the packet data mode and then returning to step (b).
A system for controlling a plurality of mobile station operation modes in a wireless communication system, comprising:
- a plurality of protocols which are operable by a mobile station in multiple modes, the multiple modes including a packet data mode and a voice mode, wherein the mobile station monitors a digital control channel (DCCH) associated with the voice mode;
- and
- means for selecting the mobile station to operate in one of said multiple modes;
- wherein if the packet data mode is selected by said selecting means, the mobile station is switched to operate in the packet data mode and then returns to monitoring the DCCH.
