Abstract
Abstract A wireless telecommunications system and method for basing the voice coder selection for the speech channel on the current location of the subscriber. Subscribers having a voice coder of less quality, such as a half-rate voice coder, can specify that while making or receiving calls in certain locations, e.g., from home or from the office, an improved voice coder should be allocated, such as the enhanced full rate voice coder. The location based voice coder selection can be implemented in either the mobile station itself or within the cellular network.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
146 words
A telecommunications system for selecting a voice coder, said system comprising: a mobile terminal having a memory therein containing voice coder location information for said mobile terminal, said voice coder location information including at least one location and an associated voice coder preference defined by a mobile subscriber associated with said mobile terminal, said mobile terminal determining a position of said given mobile terminal within said system and comparing said determined position with said at least one location within said voice coder location information to determine a select one of said at least one location; and a Mobile Services Center in wireless communication with said mobile terminal for receiving said voice coder preference associated with said select location from said mobile terminal and selecting said voice coder associated with said received voice coder preference for communication between said Mobile Services Center and said given mobile terminal.
Claim 2
Dependent Claim
146 words
A telecommunications system for selecting a voice coder, said system comprising: a mobile terminal having a memory therein containing voice coder location information for said mobile terminal, said voice coder location information including at least one location and an associated voice coder preference defined by a mobile subscriber associated with said mobile terminal, said mobile terminal determining a position of said given mobile terminal within said system and comparing said determined position with said at least one location within said voice coder location information to determine a select one of said at least one location; and a Mobile Services Center in wireless communication with said mobile terminal for receiving said voice coder preference associated with said select location from said mobile terminal and selecting said voice coder associated with said received voice coder preference for communication between said Mobile Services Center and said given mobile terminal.
Claim 3
Dependent Claim
44 words
The telecommunications system of claim 1, wherein said voice coder is selected from the group consisting of: a full-rate channel voice coder, a half-rate channel voice coder, a dual-rate channel voice coder with full-rate preferred, and a dual-rate channel voice coder with half-rate preferred.
Claim 4
Dependent Claim
26 words
The telecommunications system of claim 1, wherein said given mobile terminal has a Subscriber Identity Module therein, said memory being located in said Subscriber Identity Module.
Claim 5
Dependent Claim
46 words
The telecommunications system of claim 1, wherein said voice coder is a full-rate channel voice coder when said given mobile terminal is within a first area, and said voice coder is a half-rate channel voice coder when said given mobile terminal is within a second area.
Claim 6
Dependent Claim
79 words
The telecommunications system of claim 1, further comprising a Base Station System in wireless communication with said mobile terminal and connected to said Mobile Services Center, said Base Station System sending area information to said mobile terminal, said mobile terminal comparing said area information with said at least one location within said voice coder location information to determine said select location and sending the respective voice coder preference associated with said determined select location to said Mobile Services Center.
Claim 7
Dependent Claim
27 words
The telecommunications system of claim 5, wherein said Base Station System sends said area information to said given mobile terminal on a Short Message System broadcast channel.
Claim 8
Dependent Claim
28 words
The telecommunications system of claim 5, wherein said area information received by said given mobile terminal is stored in a Subscriber Identity Module located within said mobile terminal.
Claim 9
Independent Claim
190 words
A method for selecting a voice coder based on the location of a given one of a plurality of mobile terminals, each of said mobile terminals being in wireless communication with a Mobile Services Center within a telecommunications system, said method comprising the steps of: (a) determining a position of said given mobile terminal within said system; (b) comparing, by said given mobile terminal, said position with at least one location within voice coder location information associated with said given mobile terminal, said voice coder location information being stored in a memory within said given mobile terminal and including said at least one location and an associated voice coder preference defined by a mobile subscriber associated with said given mobile terminal; (c) determining a select one of said at least one location based upon said step of comparing: (d) sending the respective voice coder preference associated with said determined select location from said given mobile terminal to said Mobile Services Center; and (e) assigning, by said Mobile Services Center, said voice coder associated with said respective voice coder preference associated with said determined select location of said given mobile terminal.
Claim 10
Independent Claim
190 words
A method for selecting a voice coder based on the location of a given one of a plurality of mobile terminals, each of said mobile terminals being in wireless communication with a Mobile Services Center within a telecommunications system, said method comprising the steps of: (a) determining a position of said given mobile terminal within said system; (b) comparing, by said given mobile terminal, said position with at least one location within voice coder location information associated with said given mobile terminal, said voice coder location information being stored in a memory within said given mobile terminal and including said at least one location and an associated voice coder preference defined by a mobile subscriber associated with said given mobile terminal; (c) determining a select one of said at least one location based upon said step of comparing: (d) sending the respective voice coder preference associated with said determined select location from said given mobile terminal to said Mobile Services Center; and (e) assigning, by said Mobile Services Center, said voice coder associated with said respective voice coder preference associated with said determined select location of said given mobile terminal.
Claim 11
Dependent Claim
29 words
The method of claim 8, wherein said memory comprises a Subscriber Identity Module, said steps of comparing and determining said select location being performed by said Subscriber Identity Module.
Claim 12
Dependent Claim
43 words
The method of claim 8, wherein said voice coder is selected from the group consisting of: a full-rate channel voice coder, a half-rate channel voice coder, a dual-rate channel voice coder with full-rate preferred, and a dual-rate channel voice coder with half-rate preferred.
Claim 13
Dependent Claim
45 words
The method of claim 8, wherein said voice coder is a full-rate channel voice coder when said given mobile terminal is within a first area, and said voice coder is a half-rate channel voice coder when said given mobile terminal is within a second area.
Claim 14
Dependent Claim
83 words
The method of claim 8, wherein said step of determining said position of said given mobile terminal is performed by a Base Station System in wireless communication with said given mobile terminal sending area information to said given mobile terminal, said given mobile terminal comparing said area information with said at least one location within said voice coder location information to determine said select location and sending the respective voice coder preference associated with said determined select location to said Mobile Services Center.
Claim 15
Dependent Claim
26 words
The method of claim 12, wherein said Base Station System sends said area information to said given mobile terminal on a Short Message System broadcast channel.
Claim 16
