Abstract
A system for collecting within a mobile subscriber station of a cellular radio system the key elements of telephone billing information for subsequent retrieval. Information about the connected party's number, the time of the call and the duration of the call are collected in real time and stored in a non-volatile memory. Such information is selectively retrieved from the memory of the subscriber station on command and a bill for use of the subscriber station calculated on the spot (by a mobile station rental agency, for example).
Claims14
A method of producing a call log within a mobile subscriber station operating within a mobile radio system, said call log being used to collect information relating to charging for the use of said mobile subscriber station, said method comprising:
- detecting the beginning and end of a call to which said mobile subscriber station is a party;
- calculating the length of said call;
- storing within a non-volatile memory located within said subscriber station the date and length of said call;
- capturing over an air interface charging information relating to at least one party of call whenever the person in control of said mobile subscriber station is responsible for charges relating to said call, including charging information that relates to other than an outgoing call by said mobile subscriber station;
- storing within said non-volatile memory said at least one captured charging information for subsequent retrieval;
- and
- subsequently retrieving said stored information and calculating a charge for the use of said subscriber station with respect to the users participation in said call, said retrieving step further comprising the steps of:
- connecting said mobile subscriber station to a call log data retrieving module;
- sending command messages from said call log data retrieving module to said subscriber station to extract said call log data;
- and
- downloading said call log data into said call log data retrieving module.
A system for producing a call log within a mobile subscriber station operating within a mobile radio system, said call log being used to collect information relating to charging for the use of said mobile subscriber station, said system comprising:
- means for detecting the beginning and end of a call to which said mobile subscriber station is a party;
- means for calculating the length of said call;
- means for storing within a non-volatile memory located within said subscriber station the date and length of said call;
- means for capturing over an air interface charging information relating to at least one party of a call whenever the person in control of said mobile subscriber station is responsible for charges relating to said call, including charging information that relates to other than an outgoing call by said mobile subscriber station;
- means for storing within said non-volatile memory said at least one captured charging information for subsequent retrieval;
- and
- means for subsequently retrieving said stored information and calculating a charge for the use of said subscriber station with respect to the users participation in said call, said retrieving means further comprising:
- means for connecting said mobile subscriber station to a call log data retrieving module;
- means for sending command messages from said call log data retrieving module to said subscriber station to extract said call log data;
- and
- means for downloading said call log data into said call log data retrieving module.
