Method for determining service availability
First Claim
1. A method of determining the availability of at least one of a plurality of different services having different requirements in a wireless communication network comprising at least a first station and a second station which are in communication, said method comprising the step of:
- estimating the pathloss between said first station and said second station, and based on said pathloss and the maximum power with which the first station is capable of transmitting, determining the greatest service requirements which can be provided.

Abstract
A method of determining the availability of at least one of a plurality of different services in a wireless communication network comprising at least a first station and a second station which are in communication has the following steps. The pathloss between said first station and said second station is estimated, and based on the pathloss and the requirements of at least one of said services, the power with which said first station is required to transmit to said second station is determined. The required power is compared with the maximum power with which the first station is capable of transmitting.

1. A method of determining the availability of at least one of a plurality of different services having different requirements in a wireless communication network comprising at least a first station and a second station which are in communication, said method comprising the step of:
-
estimating the pathloss between said first station and said second station, and based on said pathloss and the maximum power with which the first station is capable of transmitting, determining the greatest service requirements which can be provided. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
determining if said first station is able to provide said service based on said determining step.
-
-
3. A method as claimed in claim 1 wherein said first station is arranged to estimate the pathloss between said first and second stations.
-
4. A method as claimed in claim 3, wherein the pathloss estimate is determined from information transmitted from the second station as to the power at which signals are transmitted from the second station and measurements at the first station as to the strength of signals received at the first station from the second station.
-
5. A method as claimed in claim 1 wherein the second station transmits information as to the interference levels occurring in the signals received by the second station from the first station.
-
6. A method as claimed in claim 1, wherein the determining step takes into account the interference level occurring in transmissions between said first and second stations.
-
7. A method as claimed in claim 6, wherein information relating to the maximum permitted interference level for signals which are transmitted from the first station to the second station is transmitted to the first station from the second station.
-
8. A method as claimed in claim 1, wherein the level of interference which would occur in the signals transmitted between the first and second station is estimated from the current level of interference between the first and second stations and the additional interference which would occur if the first station were to use one of said available services.
-
9. A method as claimed in claim 8, wherein the current level of interference is obtained from information provided by the second station.
-
10. A method as claimed in claim 8, wherein said level of interference is compared with a maximum level of interference.
-
11. A method as claimed in claim 10, wherein if the level of interference between the first and second stations is the same as the maximum level of interference, then it is determined that none of the plurality of services are available.
-
12. A method as claimed in claim 1, wherein an indication as to the availability of a given service is provided by said first station.
-
13. A method as claimed in claim 12 wherein the availability of a given service is displayed by said first station on a display thereof.
-
14. A method as claimed in claim 13, wherein said display includes a scale indicative of the level of service requirements which are available.
-
15. A method as claimed in claim 1, wherein said plurality of services have different minimum service requirements.
-
16. A method as claimed in claim 15, wherein at least one minimum service requirement is taken into account when determining the availability of at least one service.
-
17. A method as claimed in claim 15, wherein said service requirements include one or more of the following:
- bit rate; and
quality.
- bit rate; and
-
18. A method as claimed in claim 1, wherein information determined by the first station in the determining step is used by the wireless communication network to calculate network requirements.
-
19. A method as claimed in claim 18, wherein a power margin estimate is calculated from the difference between the maximum power and the required power and said power margin estimate is used by said wireless communication network to calculate network requirements.
-
20. A method as claimed in claim 18, wherein said network requirements comprise capacity requirements.
-
21. A method as claimed in claim 1, wherein said first station is a mobile station.
-
22. A method as claimed in claim 1, wherein said second station is a base transceiver station.
-
23. A method as claimed in claim 1, wherein said wireless communication network uses code division multiple access.
-
24. A method as claimed in claim 1, wherein said wireless communication network uses time division multiple access.
-
25. A method determining the availability of at least one of a plurality of different services in a wireless communication network comprising at least a first station and a second station which are in communication, said method comprising the steps of:
-
estimating the pathloss between said first station and said second station, and based on said pathloss and the requirements of at least one of said services, determining the power with which said first station is required to transmit to said second station;
comparing said required power with the maximum power with which the first station is capable of transmitting; and
determining the availability of services from the maximum power by determining the greatest level of service which can be provided.
-
-
26. A method of determining the availability of at least one of a plurality of different services in a wireless communication network comprising at least a first station and a second station which are in communication, said method comprising the step of:
-
estimating the interference in the signal transmitted between said first station and second station, and based on the interference and the requirements of at least one of said services determining the power with which said first station is required to transmit to said second station;
comparing said required power with the maximum power with which the first station is capable of transmitting; and
determining the availability of services from the maximum power by determining the greatest level of service which can be provided.
