Remotely programmable mobile terminal
First Claim
1. A system for programming a telephone comprising:
- a base station, and a plurality of mobile stations which communicate via said base station;
wherein each of said mobile stations comprises a telephone including a digital signal processor (DSP) having compression means for compressing outgoing voice signals, expansion means for expanding incoming voice signals, and a computer forming a part of said compression means and said expansion means;
wherein said telephone further comprises a memory for storing a first program, said first program serving to direct said computer in accordance with a predetermined protocol to accomplish said compressing and said expanding of voice signals;
wherein said system further comprises means for downloading said first program from said base station to each of said mobile stations, and means for substituting a second program in place of said first program to alter said protocol; and
wherein the DSP in one of said mobile stations differs from the DSP in another of said mobile stations and, in each of said mobile stations, said telephone is operative to transmit to said base station an identification of a type of said telephone'"'"'s DSP prior to a downloading of said first program, said base station stores a plurality of versions of said first program and of said second program, and said downloading is accomplished by matching a version of each of said first and said second programs to a type of DSP at each of said mobile stations.

Abstract
A telephone system including mobile telephonic stations provides for a remote programming of the telephones of respective ones of the mobile stations upon an indication from each of the respective telephones of a type of digital signal processor (DSP) employed by the telephone. Various programs are stored at a base station for implementing various protocols in the compression and in the expansion of voice signals processed by the DSP. Such programs include differences in the output compressed signal bandwidth to be allocated to a specific service area of a base station at a specific time of day, by way of example. Programs operating the DSP can be changed upon request of a subscriber and/or upon direction from the base station. Program changes may occur also upon a hand-off between service areas of different base stations. Plural memories may be provided in an individual telephone to permit operation with one protocol during reception of a program for a different protocol. In the event of surplus channel capacity for communication via the base station, the subscriber may request, possibly at an extra monetary charge, a higher transmission bandwidth of compressed voice signal for improved voice quality.

13. A system for programming a telephone comprising:
-
a base station, and a plurality of mobile stations which communicate via said base station; wherein each of said mobile stations comprises a telephone including a digital signal processor (DSP) having first means for applying a protocol to outgoing voice signals, second means for recovering incoming voice signals from the protocol, and a computer forming a part of said first means and said second means; wherein said telephone further comprises a memory for storing a first program, said first program serving to direct said computer in accordance with said protocol to accomplish said applying of the protocol and said recovering of voice signals from the protocol; wherein said system further comprises means for downloading said first program from said base station to each of said mobile stations, and means for substituting a second program in place of said first program to alter said protocol; and wherein the DSP in one of said mobile stations differs from the DSP in another of said mobile stations and, in each of said mobile stations, said telephone is operative to transmit to said base station an identification of a type of said telephone'"'"'s DSP prior to a downloading of said first program, said base station stores a plurality of versions of said first program and of said second program, and said downloading is accomplished by matching a version of each of said first and said second programs to a type of DSP at each of said mobile stations.
