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 telecommunication service, comprising:

determining a number of assignable logical timeslots of a logical base transceiver station;

determining a number of a plurality of physical base transceiver stations associated with the logical base transceiver station;

allocating an available set of serving physical timeslots in each of the plurality of physical base transceiver stations equal in size to the number of assignable logical timeslots of the logical base transceiver station divided by the number of the plurality of physical base transceiver stations associated with the logical base transceiver station;

receiving an outbound call traffic assigned to an assignable logical timeslot of the logical base transceiver station; and

remapping the assigned logical timeslot to a serving physical timeslot from among the available set of serving physical timeslots among the plurality of physical base transceiver stations associated with the logical base transceiver station.

2. The method of claim 1, further comprising:

receiving an inbound call traffic associated with a second serving physical timeslot from among the available set of serving physical timeslots from at least one of the plurality of physical base transceiver stations; and

remapping the second serving physical timeslot to a second assigned logical timeslot from among the assignable logical timeslots of the logical base transceiver station.

3. The method of claim 1, wherein the inbound call traffic comprises:

inbound call traffic received from at least one of the plurality of physical base transceiver stations via an IP network.

4. The method of claim 1, wherein the receiving comprises:

receiving the outbound call traffic at an aggregation gateway.

5. The method of claim 1, wherein at least one of the plurality of physical base transceiver stations comprise a small scale physical base transceiver station.

6. The method of claim 5, wherein the small scale physical base transceiver station is deployed to at least one of:

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

7. The method of claim 1, further comprising:

receiving an indication to set up the outbound call traffic; and

assigning the outbound call traffic to the assigned logical timeslot.

8. The method of claim 1, further comprising:

storing a mapping data that associates the assigned logical timeslot with the serving physical timeslot.

9. The method of claim 8, further comprising:

remapping the assigned logical timeslot to the serving physical timeslot using the mapping data.

10. The method of claim 1, further comprising:

remapping the assigned logical timeslot to the serving physical timeslot by altering a timeslot identifier data included in the outbound call traffic.

11. The method of claim 1, further comprising:

propagating a broadcast control channel message associated with a broadcast control timeslot of the logical base transceiver station to a corresponding broadcast timeslot of each of the plurality of physical base transceiver stations.

12. The method of claim 1, further comprising:

propagating a packet data channel message associated with a packet data channel timeslot of the logical base transceiver station to a corresponding packet data channel timeslot of each of the plurality of physical base transceiver stations.

13. A telecommunication system, comprising:

a communication interface configured to receive an outbound call traffic assigned to an assignable logical timeslot of a logical base transceiver station, and

a processor, coupled to a communication interface, configured to;

determine a number of assignable logical timeslots of the logical base transceiver station;

determine a number of a plurality of physical base transceiver stations associated with the logical base transceiver station;

allocate an available set of serving physical timeslots in each of the plurality of physical base transceiver stations equal in size to the number of assignable logical timeslots of the logical base transceiver station divided by the number of the plurality of physical base transceiver stations associated with the logical base transceiver station; and

remap the assigned logical timeslot to a serving physical timeslot from among the available set of physical timeslots among the plurality of physical base transceiver stations associated with the logical base transceiver station.

14. The telecommunication system of claim 13, wherein the telecommunication system comprises:

an aggregation gateway configured to communicate via an IP network with the plurality of physical base transceiver stations.

15. The telecommunication system of claim 13, wherein the processor is further configured to forward an inbound call traffic to a base station controller and forward the outbound call traffic to at least one of the plurality of physical base transceiver stations.

16. A method of providing telecommunication service, comprising:

determining a number of assignable logical timeslots of a logical base transceiver station;

determining a number of a plurality of physical base transceiver stations associated with the logical base transceiver station;

allocating an available set of serving physical timeslots in each of the plurality of physical base transceiver stations equal in size to the number of assignable logical timeslots of the logical base transceiver station divided by the number of the plurality of physical base transceiver stations associated with the logical base transceiver station;

receiving an outbound call traffic assigned to an assignable logical timeslot of the logical base transceiver station;

remapping the assigned logical timeslot to a serving physical timeslot from among the available set of serving physical timeslots among the plurality of physical base transceiver stations associated with the logical base transceiver station; and

configuring at least one of the plurality of physical base transceiver stations to operate at a frequency corresponding to the assigned logical timeslot.

17. The method of claim 16, wherein the logical base transceiver station comprises a logical transceiver associated with the frequency corresponding to the assigned logical timeslot.

18. The method of claim 17, wherein the at least one physical base transceiver station comprises a physical transceiver configured to operate at the frequency corresponding to the assigned logical timeslot.
