Allocating idle time to a mobile station
First Claim
Patent Images
1. A method for allocating idle time in a mobile communication system during a communications connection between a mobile station and a network, comprising:
- a) the mobile station sending to the network an idle time request; and
b) the network allocating to the mobile station at least part of the idle time requested by the mobile station and informing the mobile station about at least the time when the idle time will be available.

Abstract
A mobile station (10) can request (100) idle time from a network (20) e.g. for measuring the strengths of signals from base stations. Having received the request the network checks (110) whether suitable idle time is coming up and if not, allocates (120) idle time according to the request by the mobile station. Finally, the network informs (130) the mobile station about when and how much the mobile station has measurement time available.

3. The method of claim 2, further comprising repeating b) at least once.
-
4. The method of claim 3, further comprising the mobile station additionally indicating to the network how many times the network will repeat b).
-
5. The method of claim 3, further comprising the mobile station sending to the network a command for ending or changing the repeating of a particular idle time period.
-
6. The method of claim 2, wherein the network allocates idle time by stealing at least one burst.
-
7. The method of claim 2, wherein the network allocates idle time by swapping time slots used by two or more mobile stations.
-
8. The method of claim 2, wherein the network allocates idle time by interrupting the communications between the mobile station and a base station of the system for a predetermined period of time.
-
9. The method of claim 1, further comprising the network sending to the mobile station information related to beacon signals transmitted by base stations.
-
10. The method of claim 9, wherein said information includes at least one of the following:
-
frequencies of the beacon signal of at least one neighbour cell, bandwidth of the beacon signal of at least one neighbour cell, timing information of the beacon signal of at least one neighbour cell, timing information of frequency and time synchronisation signals of the beacon signal of at least one neighbour cell, frequency hopping or spread spectrum code information of the beacon signal of at least one neighbour cell, or information about the continuity or discontinuity of the beacon signal of at least one neighbour cell.
