Abstract
A base station comprises a plurality of transceivers, one of which normally performs verifications, but is able to handle traffic channels at time of high demand. When it is desired to block one transceiver, for example for maintenance purposes, calls allocated to that transceiver can be handed off to other transceivers before the device is fully blocked.
Claims16
A base station, comprising a first number N of transceivers, each having a transmission frequency allocated thereto, and having a second number P of time slots, and one of the transceivers being designated as a verification device, wherein one of the time slots on a transceiver other than the verification device is designated as a control channel, and all {P*(N-1)-1} other time slots on the transceiver or transceivers other than the verification device are designated as traffic channels, and wherein the P time slots on the verification device are available for use as traffic channels.
A method of operation of a base station comprising a first number N of transceivers, each having a transmission frequency allocated thereto, and having a second number P of time slots, the method comprising the steps of:
- designating one of the transceivers as a verification device,
- designating one of the time slots on a transceiver other than the verification device as a control channel, and
- designating all {P*(N-1)-1} other time slots on the transceiver or transceivers other than the verification device as traffic channels, while making the P time slots on the verification device available for use as traffic channels.
A method of performing a verification using a verification transceiver in a base station comprising a first number N of transceivers, each having a transmission frequency allocated thereto, and having a second number P of time slots, the method comprising:
- designating one of the N transceivers as said verification transceiver;
- designating one of the P time slots on a transceiver other than the verification transceiver as a control channel;
- designating all {P*(N-1)-1} other time slots on the transceivers other than the verification transceiver as traffic channels, while making the P time slots on the verification transceiver available for use as traffic channels, wherein a group of time slots from a frame period,
- performing a verification by returning the verification transceiver from the transmission frequency thereof to an operating frequency of a mobile for at least one frame period to perform the verification, and
- returning the verification transceiver to its transmission frequency when the verification has been performed.
A base station, comprising a first number N of transceivers, each having a transmission frequency allocated thereto, and having a second number P of time slots, and one of the N transceivers being designated as a verification device, wherein one of the P time slots on a transceiver other than the verification device is designated as a control channel, and all {P*(N-1)-1} other time slots on the transceivers other than the verification device are designated as traffic channels, and wherein the P time slots on the verification device are available for use as traffic channels, the verification device being controllable to retune to an operating frequency of a mobile for at least one frame period, to perform a verification on said mobile.
A base station, comprising a plurality of transceivers, and being programmed, on receipt of a blocking signal to one of the transceivers, to hand off any calls presently using said one of the plurality of transceivers to another transceiver, or to respective other transceivers, and blocking said one of the plurality of transceivers only when all calls presently using said one of the plurality of transceivers have been handed off or terminated.
A method of blocking a transceiver of a base station having a plurality of transceivers, the method comprising sending a blocking signal to the transceiver, handing off all calls presently using the transceiver to the other transceiver, or to respective other transceivers, and blocking the transceiver only when all calls presently using the transceiver have been handed off or terminated.
