Abstract

Using a single logical base transceiver to serve multiple physical locations is disclosed. A call traffic associated with a call associated at a mobile network with an assigned timeslot of a logical base transceiver is received. A timeslot with which the call traffic is associated is remapped from the assigned timeslot to a serving timeslot being used at a serving physical base transceiver to facilitate the call, in the event the call traffic comprises inbound call traffic being sent into the mobile network from the serving physical base transceiver, or from the serving timeslot to the assigned timeslot in the event the call traffic comprises outbound call traffic being sent from the mobile network to the serving physical base transceiver.

Claims

1. A method of providing mobile telecommunication service, comprising:

receiving a call traffic associated with a call associated at a mobile network with an assigned timeslot of a logical base transceiver; and

remapping a timeslot with which the call traffic is associated from the assigned timeslot to a serving timeslot being used at a serving physical base transceiver to facilitate the call, in the event the call traffic comprises inbound call traffic being sent into the mobile network from the serving physical base transceiver, or from the serving timeslot to the assigned timeslot in the event the call traffic comprises outbound call traffic being sent from the mobile network to the serving physical base transceiver.

2. A method as recited in claim 1, wherein the logical base transceiver comprises a logical base transceiver station (BTS).

3. A method as recited in claim 1, wherein the call traffic comprises inbound call traffic received from the serving physical base transceiver via an IP network.

4. A method as recited in claim 3, wherein the call traffic is received at an aggregation gateway (AGW).

5. A method as recited in claim 1, wherein the serving physical base transceiver comprises a small scale base transceiver station (S-BTS).

6. A method as recited in claim 5, wherein the S-BTS is deployed to one or more of the following:

a residence, a business, and a geographically remote or isolated area.

7. A method as recited in claim 1, further comprising receiving an indication that the call is being set up and assigned to the assigned timeslot.

8. A method as recited in claim 7, further comprising storing a mapping data that associates the assigned timeslot with the serving timeslot.

9. A method as recited in claim 8, wherein the mapping data is used to remap the timeslot.

10. A method as recited in claim 1, wherein remapping the timeslot comprises altering a timeslot identifier data included in the call traffic.

11. A method as recited in claim 1, further comprising propagating to a corresponding timeslot of each of a plurality if physical base transceivers a broadcast control channel (BCCH) message associated with a broadcast control channel of the logical base transceiver.

12. A method as recited in claim 1, further comprising propagating to a corresponding timeslot of each of a plurality if physical base transceivers a packet data channel (PDCH) message associated with a packet data channel of the logical base transceiver.

13. A mobile telecommunication system, comprising:

a communication interface configured to receive a call traffic associated with a call associated at a mobile network with an assigned timeslot of a logical base transceiver; and

a processor coupled to the communication interface and configured to remap a timeslot with which the call traffic is associated from the assigned timeslot to a serving timeslot being used at a serving physical base transceiver to facilitate the call, in the event the call traffic comprises inbound call traffic being sent into the mobile network from the serving physical base transceiver, or from the serving timeslot to the assigned timeslot in the event the call traffic comprises outbound call traffic being sent from the mobile network to the serving physical base transceiver.

14. A mobile telecommunication system as recited in claim 13, wherein the mobile telecommunication system comprises an aggregation gateway configured to communicate via an IP network with a plurality of physical base transceivers.

15. A mobile telecommunication system as recited in claim 13, wherein the processor is further configured to forward the call traffic, subsequent to remapping the timeslot, to a base station controller (BSC) in the case of inbound call traffic or to the serving physical base transceiver in the case of outbound call traffic.

16. A computer program product for providing mobile telecommunication service, the computer program product being embodied in a computer readable medium and comprising computer instructions for:

receiving a call traffic associated with a call associated at a mobile network with an assigned timeslot of a logical base transceiver; and

remapping a timeslot with which the call traffic is associated from the assigned timeslot to a serving timeslot being used at a serving physical base transceiver to facilitate the call, in the event the call traffic comprises inbound call traffic being sent into the mobile network from the serving physical base transceiver, or from the serving timeslot to the assigned timeslot in the event the call traffic comprises outbound call traffic being sent from the mobile network to the serving physical base transceiver.

17. A method of providing mobile telecommunication service, comprising:

receiving an indication that a call to be provided via a serving physical base transceiver is associated at a mobile network with an assigned timeslot of a logical base transceiver; and

configuring the serving physical base transceiver to operate with respect to a serving timeslot of the serving physical base transceiver, which serving timeslot corresponds to the assigned timeslot of the logical base transceiver, at a selected one of a plurality of frequencies at which the serving physical base transceiver is configured to operate with respect to the serving timeslot, the selected frequency corresponding to an assigned frequency associated at the mobile network with the logical base transceiver.

18. A method as recited in claim 17, wherein the logical base transceiver comprises one of a plurality of logical transceivers (TRX) associated at the mobile network with a logical base transceiver station (BTS), each such logical transceiver is associated at the mobile network with a corresponding one of the plurality of frequencies, and the serving physical base transceiver comprises one of a plurality of physical base transceiver stations that the logical base transceiver station is being used to support.

19. A method as recited in claim 18, wherein each of said physical base transceiver stations comprises a physical base transceiver (TRX) configured to operate as required, one each of a plurality of physical base transceiver timeslots, at a selected one of the plurality of frequencies.
