Abstract
A mobile telephone remote programming system and method includes a mobile telephone that has a subscriber ID module (SIM) which can store control data for voice message actuation and vocoder parameters. The telephone is adapted to receive digital programming information over a radio communication link. The programming information is adapted to modify the contents of the SIM to include updated voice message actuation data and/or vocoder data. The telephone uses the stored data to control voice message actuation and/or vocoder operation.
Claims5
A mobile telephone comprising:
- a vocoder with changeable control parameters;
- automatic dialing means responsive to stored digital information;
- a subscriber ID module removably mated to a slot of said telephone having storage space to hold subscriber pertinent data including at least data for controlling said vocoder and for actuation of voice message retrieval;
- means for receiving digital programming data through a radio communication channel;
- means for programming the storage space in said subscriber ID module according to the received digital programming data;
- means for modifying the changeable control parameters of the vocoder according to the data of vocoder parameters stored in said storage space;
- and
- means using said voice message retrieval data stored in said storage space for automatically dialing a telephone number and retrieving voice message.
In a mobile telephone having a vocoder for digitizing and compressing voice data wherein the vocoder has a plurality of changeable control parameters, a method for remotely administering the vocoder parameters comprising:
- establishing a digital communication link between said mobile telephone and a distant control center;
- downloading vocoder control parameters from said distant control center to a removably mated storage module in said mobile telephone;
- and
- modifying the vocoder parameters in said mobile telephone in accordance with said vocoder control parameters stored in said storage module.
In a mobile telephone having a keyboard and automatic dialing means responsive to digital data stored in a subscriber ID module removably mated to said telephone, the method for automatically retrieving voice messages from a distant voice message center comprising:
- establishing a digital communication link between said mobile telephone and a distant control center;
- downloading voice message retrieval control data from said distant control center to said subscriber ID module mated to said mobile telephone;
- storing said voice message retrieval control data in said subscriber ID module;
- and
- in response to pressing a designated key on said keyboard, automatically dialing and retrieving voice messages from said voice message center using the voice message retrieval control data stored in said subscriber ID module.
