Abstract

A method for obtaining service when in a no-coverage area (11) of a radiotelephone communication system (18) includes a first step of storing (32) information regarding a last known available communication system. This can be accomplished through the communication system (18) when loss of service is imminent or through independent means after service is lost. A next step includes reporting (34) the information about the last known available communication system (12) to a user of the radiotelephone (10). A next step includes using (36) the information to obtain service from the last known available communication system (12). For example, a user could use timing information to backtrack their steps or use location information to obtain service.

Claims

AMENDED CLAIMS [received by the International Bureau on 13th October 2005 (13.10.05); original claims 9-14, 16, 18 and 19 have been cancelled; remaining original claims 1-8, 15, 17 and 20 have been renumbered 1-11]
1. A method for obtaining service when in a no-coverage area of a radiotelephone communication system, the method comprising the steps of: storing information regarding a last known available communication system; reporting the information about the last known available communication system to a user of the radiotelephone; and using the information to obtain service from the last known available communication system.
2. The method of claim 1, wherein the information in the storing step includes recording information about a time since the radiotelephone was last in contact with the communication system, and wherein the reporting step includes reporting the time information to the user.
3. The method of claim 1, wherein the information in the storing step includes recording information about a location where the radiotelephone was last in contact with the communication system, and wherein the reporting step includes reporting the location information to the user.
4. The method of claim 3, further comprising the step of determining directional information to the location from the storing step, and wherein the reporting step includes reporting the directional information to a user to follow to obtain service from the last known available communication system.
5. The method of claim 1, wherein the storing step includes determining a location of the last known available communication system using a location system independent of the communication system itself.
6. The method of claim 1, further comprising the step of estimating that a loss of service from the communication system is imminent, and wherein the storing step includes using information from the communication system to determine a location of available service before service is lost from the communication system.
7. The method of claim 1, further comprising a step of detecting signals from a communication system that is too far away for two-way communication with the radiotelephone, and the reporting step includes reporting to the user whether a strongest of such signals is from the last known available communication system.
8. The method of claim 1, further comprising a step of detecting signals from location-broadcasting network access points of the communication system that are too far away for two-way communication with the radiotelephone, and wherein the storing step includes recording the broadcasted locations of network access points from the detecting step, and wherein the reporting step includes reporting the broadcasted locations of the network access points from the detecting step to the user.
9. A mobile radiotelephone operable to obtain service when in a no-coverage area of a communication network, the radiotelephone comprising: a user interface; a memory; a processor coupled to the user interface and the memory, the processor controls radio commumcation circuitry for communication with the communication network, wherein the processor stores information regarding the last known available service from the communication network in the memory and reports this information to a user of the radiotelephone through the user interface when the radiotelephone is in a no- coverage area, such that the user can use this information to obtain service from the last known available communication network.
10. The radiotelephone of claim 9, wherein the processor calculates and displays directions on the user interface for a user to follow to obtain service from the communication network.
15
11. The radiotelephone of claim 9, wherein the processor detects signals from a communication system that is too far away for two-way communication with the radiotelephone, determines whether a strongest of such signals is from the communication network, and reports this information on the user interface.
