Abstract

A system, method, and computer readable medium for abbreviated dialing in a femtocell network is provided. A user having authorized access to the femtocell network may dial another authorized user using an abbreviated code. On receipt of the call request, a femtocell system may evaluate the destination number to determine if it is an abbreviated code. If the dialed number is not an abbreviated code, the femtocell system may direct the call request to the telecommunication core network for processing thereby. If the dialed number is evaluated by the femtocell system as an abbreviated code, the femtocell system may direct the call request to an on-site PBX for call handling. If the abbreviated code is a valid code and the dialed user equipment is currently in the femtocell network service area, the PBX may then complete the call setup within the femtocell network.

Claims

1. A method of call processing in a network system comprising a femtocell network comprising a private branch exchange of the femtocell network and a plurality of femtocells connected to the private branch exchange, the method comprising:

receiving, by a first femtocell of the plurality of femtocells, a call setup request from a first user equipment;

performing in the first femtocell an evaluation of a destination number of a second user equipment to which the call is directed; and

determining, based on results of the evaluation, the call setup request is to be directed to one of the private branch exchange deployed in the femtocell network and a telecommunication core network communicatively coupled with the femtocell network, wherein the call is directed to the private branch exchange deployed in the femtocell network if the destination number is evaluated to be an abbreviated code of a telephone number derived from the destination number and the call is directed to the core network if the destination number is evaluated not to be an abbreviated code.

2. The method of claim 1, where performing an evaluation comprises determining the destination number comprises an abbreviated code.

3. The method of claim 2, where the abbreviated code comprises a four-digit number.

4. The method of claim 2, further comprising transmitting the call setup request to the private branch exchange.

5. The method of claim 4, further comprising:

determining that the second user equipment is located in a service area of a femtocell network; and

setting up the call in the femtocell network.

6. The method of claim 4, further comprising:

determining that the second user equipment is not located in a service area of the femtocell network; and

setting up the call in the telecommunication core network.

7. The method of claim 1, where performing an evaluation comprises determining the destination number does not comprise an abbreviated code.

8. The method of claim 7, further comprising transmitting the call setup request to the telecommunication core network for processing thereby.

9. A non-transitory computer-readable medium having computer-executable instructions for execution by a processing system, the computer-executable instructions for call processing in a network system, the computer-readable medium comprising instructions that:

receive, by a first femtocell of a femtocell network comprising a plurality of femtocells connected to a private branch exchange, a call setup request from a first user equipment;

perform within the femtocell an evaluation of a destination number of a second user equipment to which the call is directed, wherein the evaluation determines if the destination number comprises an abbreviated code; and

determine, based on results of the evaluation, the call setup request is to be directed to one of the private branch exchange and a telecommunication core network communicatively coupled with the femtocell network, wherein the call is directed to the private branch exchange deployed in the femtocell network if the destination number is evaluated to be an abbreviated code of a telephone number derived from the destination number and the call is directed to the core network if the destination number is evaluated not to be an abbreviated code.

10. The non-transitory computer-readable medium of claim 9, wherein the instructions that perform the evaluation determine the destination number comprises a four-digit abbreviated code.

11. The non-transitory computer-readable medium of claim 10, further comprising instructions that transmit the call setup request to the private branch exchange.

12. The non-transitory computer-readable medium of claim 11, further comprising instructions that:

determine that the second user equipment is located in a service area of a femtocell network; and

set up the call in the femtocell network.

13. The non-transitory computer-readable medium of claim 11, further comprising instructions that:

determine that the second user equipment is not located in a service area of the femtocell network; and

set up the call in the telecommunication core network.

14. The non-transitory computer-readable medium of claim 9, wherein the instructions that perform an evaluation comprise instructions that determine the destination number does not comprise an abbreviated code.

15. The non-transitory computer-readable medium of claim 14, further comprising instructions that transmit the setup request to the telecommunication core network for processing thereby.

16. A system configured for call processing in a network system, comprising:

a packet-switched network;

an IP Multimedia subsystem communicatively coupled with the packet-switched network; and

a femtocell network communicatively coupled with the packet-switched network, the femtocell network comprising a private branch exchange of the femtocell network and a plurality of femtocells connected to the private branch exchange, wherein the private branch exchange maintains a data structure that associates directory numbers of authorized user equipments with abbreviated codes, wherein the femtocell network includes a first femtocell that receives a call setup request from a first user equipment, performs an evaluation to determine whether a destination number of a second user equipment to which the call setup request is directed comprises an abbreviated code, and determines, based on results of the evaluation, the call setup request is to be directed to one of the private branch exchange and the IP Multimedia subsystem, wherein the call is directed to the private branch exchange deployed in the femtocell network if the destination number is evaluated to be an abbreviated code of a telephone number derived from the destination number and the call is directed to the core network if the destination number is evaluated not to be an abbreviated code.

17. The system of claim 16, wherein the femtocell determines the destination number comprises a four-digit abbreviated code.

18. The system of claim 17, wherein the femtocell transmits the setup request to the private branch exchange.

19. The system of claim 18, wherein the private branch exchange determines that the second user equipment is located in a service area of a femtocell network and sets up the call in the femtocell network.

20. The system of claim 18, wherein the private branch exchange determines that the second user equipment is not located in a service area of the femtocell network and transmits the call setup request to the IP Multimedia subsystem for processing of the call set up request.
