Abstract

A mobile application gateway configured to interconnect mobile communication devices on a cellular network with an enterprise network is provided. The mobile application gateway includes a voice and data signaling gateway configured to provide routing functionalities, service functionalities and admission control. A gateway GPRS support node (GGSN) is configured to establish a secure data session between one or more of the mobile communication devices and the enterprise network by establishing a GPRS tunneling protocol (GTP) tunnel between a carrier-hosted serving GPRS support node (SGSN) and the GGSN.

Claims

1. A method comprising:

originating a first call leg between a subscriber and a carrier gateway server;

identifying a call line preference via outgoing call digits from the subscriber specifying a call line to use for an outgoing call;

originating the outgoing call to an intended destination on the specified call line to establish an outgoing call leg;

connecting the outgoing call leg with the first call leg; and

forwarding the call to an enterprise gateway server communicatively coupled to the carrier gateway server;

wherein the call line preference is maintained for a predetermined period of time;

wherein the call line preference and the predetermined period of time are stored in a subscriber profile which is accessed automatically based on at least one subscriber action.

2. The method of claim 1, further comprising selecting a primary line assigned to the subscriber to route the call.

3. The method of claim 1, further comprising:

receiving additional outgoing call digits from a subsequent outgoing call from the subscriber; and

forwarding the outgoing call on a default primary line or the specified line associated with the call line preference.

4. The method of claim 3, wherein the additional outgoing call digits do not specify a call line preference.

5. The method of claim 1, further comprising resetting the specified call line to a default call line once the predetermined period of time expires.

6. The method of claim 1, wherein the enterprise gateway server routes the outgoing call to the intended destination based on criteria comprising at least one of a time of day and a predetermined call routing setting.

7. The method of claim 1, wherein the subscriber action comprises at least one of the subscriber accessing a computer terminal and accessing a security work facility.

8. An apparatus comprising:

a receiver configured to receive a first call leg from a subscriber;

a processor configured to identify a call line preference via outgoing call digits from the subscriber that specify a call line to use for an outgoing call; and

a transmitter configured to originate the outgoing call to an intended destination on the specified call line to establish an outgoing call leg, connect the outgoing call leg with the first call leg, forward the call to an enterprise gateway server communicatively coupled to the carrier gateway server;

wherein the processor is further configured to maintain the call line preference for a predetermined period of time;

wherein the call line preference and the predetermined period of time are stored in a subscriber profile which is accessed automatically based on at least one subscriber action.

9. The apparatus of claim 8, wherein the processor is further configured to select a primary line assigned to the subscriber to route the call.

10. The apparatus of claim 8, wherein the receiver is further configured to receive additional outgoing call digits from a subsequent outgoing call from the subscriber, and the transmitter is further configured to forward the outgoing call on a default primary line or the specified line associated with the call line preference.

11. The apparatus of claim 10, wherein the additional outgoing call digits do not specify a call line preference.

12. The apparatus of claim 8, wherein the processor is further configured to reset the specified call line to a default call line once the predetermined period of time expires.

13. The apparatus of claim 8, wherein the enterprise gateway server routes the outgoing call to the intended destination based on criteria comprising at least one of a time of day and a predetermined call routing setting.

14. The apparatus of claim 8, wherein the subscriber action comprises at least one of the subscriber accessing a computer terminal and accessing a security work facility.

15. A non-transitory computer readable storage medium configured to store instructions that when executed causes a processor to perform:

originating a first call leg between a subscriber and a carrier gateway server;

identifying a call line preference via outgoing call digits from the subscriber specifying a call line to use for an outgoing call;

originating the outgoing call to an intended destination on the specified call line to establish an outgoing call leg;

connecting the outgoing call leg with the first call leg; and

forwarding the call to an enterprise gateway server communicatively coupled to the carrier gateway server;

wherein the call line preference is maintained for a predetermined period of time;

wherein the call line preference and the predetermined period of time are stored in a subscriber profile which is accessed automatically based on at least one subscriber action.

16. The non-transitory computer readable storage medium of claim 15, wherein the processor is further configured to perform selecting a primary line assigned to the subscriber to route the call.

17. The non-transitory computer readable storage medium of claim 15, wherein the processor is further configured to perform:

receiving additional outgoing call digits from a subsequent outgoing call from the subscriber; and

forwarding the outgoing call on a default primary line or the specified line associated with the call line preference.

18. The non-transitory computer readable storage medium of claim 17, wherein the additional outgoing call digits do not specify a call line preference.

19. The non-transitory computer readable storage medium of claim 15, wherein the processor is further configured to perform resetting the specified call line to a default call line once the predetermined period of time expires.

20. The non-transitory computer readable storage medium of claim 15, wherein the subscriber action comprises at least one of the subscriber accessing a computer terminal and accessing a security work facility.
