Abstract

Abstract In connection with paging displacement operation, a mobile station delays entry into sleep mode in order to read a specified number of subsequent alternate (i.e., every other) additional paging channel slots to receive a paging message. During the paging channel slots located between those designated for reading paging displacement related paging messages, the mobile station makes more efficient use of limited battery supplied energy resources by making any requisite signal strength measurements.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 103 words
A method for integrating paging channel displacement operation and downlink signal strength measurement operation with respect to mobile station operation, comprising the steps of: reading a certain number of every other paging channel designated slots of a forward control channel following an assigned paging channel slot for mobile station paging messages during the paging channel displacement operation; and making downlink signal strength measurements within the paging channel displacement operation, the measurements made during those paging channel designated slots following the assigned paging channel slot that are located between the certain number of every other paging channel designated slots of the forward control channel.
Claim 2
Independent Claim 103 words
A method for integrating paging channel displacement operation and downlink signal strength measurement operation with respect to mobile station operation, comprising the steps of: reading a certain number of every other paging channel designated slots of a forward control channel following an assigned paging channel slot for mobile station paging messages during the paging channel displacement operation; and making downlink signal strength measurements within the paging channel displacement operation, the measurements made during those paging channel designated slots following the assigned paging channel slot that are located between the certain number of every other paging channel designated slots of the forward control channel.
Claim 3
Dependent Claim 29 words
The method as in claim 1 further including the step of entering into a sleep mode of operation following the reading of the every other paging channel designated slots.
Claim 4
Dependent Claim 26 words
The method as in claim 1 further including the step of entering into a sleep mode of operation following reading of a mobile station paging message.
Claim 5
Dependent Claim 32 words
The method as in claim 1 wherein the paging channel designated slots are located within a short message service (SMS) point-to-point, paging and access response channel (SPACH) of the forward control channel.
Claim 6
Dependent Claim 116 words
A mobile station, comprising: a transceiver for reading a forward control channel for paging messages, and for making downlink signal strength measurements; and a processor connected to the transceiver and operating to cause the transceiver during a paging channel displacement operation to read a certain number of every other paging channel designated slots of the forward control channel following an assigned paging channel slot for mobile station paging messages, and further make downlink signal strength measurements within the paging channel displacement operation, the measurements made during those paging channel designated slots following the assigned paging channel slot that are located between the certain number of every other paging channel designated slots of the forward control channel.
Claim 7
Dependent Claim 116 words
A mobile station, comprising: a transceiver for reading a forward control channel for paging messages, and for making downlink signal strength measurements; and a processor connected to the transceiver and operating to cause the transceiver during a paging channel displacement operation to read a certain number of every other paging channel designated slots of the forward control channel following an assigned paging channel slot for mobile station paging messages, and further make downlink signal strength measurements within the paging channel displacement operation, the measurements made during those paging channel designated slots following the assigned paging channel slot that are located between the certain number of every other paging channel designated slots of the forward control channel.
Claim 8
Dependent Claim 36 words
The mobile station as in claim 5 further including means for denying power to the transceiver to cause entry into a sleep mode of operation following the reading of the every other paging channel designated slots.
Claim 9
Dependent Claim 33 words
The mobile station as in claim 5 further including means for denying power to the transceiver to cause entry into a sleep mode of operation following reading of a mobile station paging message.
Claim 10
Dependent Claim 33 words
The mobile station as in claim 5 wherein the paging channel designated slots are located within a short message service (SMS) point-to-point, paging and access response channel (SPACH) of the forward control channel.
