Abstract
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.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
86 words
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.
Claim 2
Independent Claim
86 words
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.
Claim 3
Dependent Claim
23 words
A method according to claim 1, wherein the selection at step (b) is performed by the mobile station user from a display device.
Claim 4
Dependent Claim
18 words
A method according to claim 1, wherein the selection at step (b) is performed by a telemetric device.
Claim 5
Independent Claim
101 words
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).
Claim 6
Independent Claim
101 words
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).
Claim 7
Dependent Claim
23 words
A method according to claim 4, wherein the selection at step (c) is performed by the mobile station user from a display device.
Claim 8
Dependent Claim
18 words
A method according to claim 4, wherein the selection at step (c) is performed by a telemetric device.
Claim 9
Dependent Claim
21 words
A method according to claim 4, wherein said packet data mode is a D-AMPS packet data mode or a CDPD mode.
Claim 10
Dependent Claim
22 words
A method according to claim 4, wherein said step (b) is performed while the mobile station is operating in a sleep mode.
Claim 11
Independent Claim
104 words
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.
Claim 12
Independent Claim
104 words
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.
Claim 13
Dependent Claim
28 words
The system according to claim 9, further comprising a telemetric device which provides data for selecting said multiple modes of operation to be performed by the mobile station.
Claim 14
Dependent Claim
29 words
The system according to claim 9, further comprising means for displaying said multiple modes of operation which may be selected by a user and performed by the mobile station.
Claim 15
Dependent Claim
21 words
The system according to claim 9 wherein the packet data mode is a D-AMPS packet data mode or a CDPD mode.
Claim 16
Dependent Claim
21 words
The system according to claim 9 wherein said monitoring is performed while the mobile station is operating in a sleep mode.
