Abstract

Aspects of the subject disclosure may include, for example, control signals are communicated with a base station of a radio access network in communication with a mobile device. The control signals include information associated with one of mobility of the mobile device, bearer management or both. The network node communicates bearer message traffic with the base station and coordinates an exchange of data packets between the base station and an external packet data network by way of the bearer message traffic. Other embodiments are disclosed.

Claims

1. A device comprising:

a processor; and

a memory storing executable instructions that, when executed by the processor, perform operations comprising;

communicating signaling message traffic to a base station of a radio access network in communication with a mobile communication device, wherein the signaling message traffic comprises information associated with one of mobility management processing, bearer management, or both of an evolved packet core;

determining whether the signaling message traffic is related to a first service or a second service; and

controlling an exchange of data packets, that are to or from the mobile communication device, between the base station and an external packet data network via a gateway, wherein the controlling comprises providing a bearer, for the data packets that are exchanged, having a higher bandwidth characteristic selected from a group of bandwidth characteristics that include a lower bandwidth characteristic and the higher bandwidth characteristic, and wherein the bearer having the higher bandwidth characteristic is provided responsive to a determination that the signaling message traffic relates to the first service.

2. The device of claim 1, wherein the operations further comprise communicating bearer message traffic to the base station, wherein the communicating of the signaling message traffic comprises a mobility management entity function and wherein the communicating of the bearer message traffic comprises a serving gateway function, each of the mobility management entity function and the serving gateway function comprising a respective core logic function of a common virtual machine.

3. The device of claim 2, wherein the signaling message traffic comprises 3^rd Generation Partnership Protocol, long term evolution (LTE) signaling messages, and wherein the communicating of the signaling message traffic is accomplished without using an S11 interface.

4. The device of claim 1, wherein the operations further comprise one of a probe function, a radio access network analytic function, an access selection function, or a combination thereof.

5. The device of claim 1, wherein the bearer for the data packets that are exchanged has one of a higher quality of service characteristic or a lower quality of service characteristic, wherein the bearer for the data packets that are exchanged has the higher quality of service characteristic responsive to the determination that the signaling message traffic relates to the first service and wherein the bearer for the data packets that are exchanged has the lower quality of service characteristic responsive to a determination that the signaling message traffic relates to the second service.

6. The device of claim 1, wherein the bearer for the data packets that are exchanged has the lower bandwidth characteristic responsive to a determination that the signaling message traffic relates to the second service.

7. The device of claim 1, wherein the first service is one of a streaming media service or a voice over IP service and the second service is an SMS service.

8. The device of claim 1, wherein the gateway comprises a packet data network gateway;

and wherein the operations further comprise combining more than one of a radio network controller functionality, a femtocell gateway functionality and a home eNodeB gateway functionality.

9. A method comprising:

communicating, by a network device including a processor, control signals to a base station of a radio access network in communication with a mobile device, wherein the control signals include information associated with one of mobility of the mobile device, bearer management, or both;

determining whether the control signals are related to a first service or a second service; and

coordinating by the network device an exchange of data packets, that are to or from the mobile device, between the base station and an external packet data network, wherein the coordinating comprises providing a bearer, for the data packets that are exchanged, having a stricter latency tolerance selected from a group of latency tolerances that include a less strict latency tolerance and the stricter latency tolerance, and wherein the bearer having the stricter latency tolerance is provided responsive to a determination that the control signals relate to the first service.

10. The method of claim 9, further comprising communicating, by the network device, bearer message traffic to the base station, wherein the communicating of the control signals comprises a mobility management entity function and wherein the communicating of the bearer message traffic comprises a serving gateway function, each of the mobility management entity function and the serving gateway function comprising a respective core logic function of a common virtual machine.

11. The method of claim 9, further comprising:

receiving, by the network device, other control signals from the base station, and

wherein the communicating of the control signals and the other control signals comprises using multiple different standard logical interfaces.

12. The method of claim 9, further comprising combining, by the network device, more than one of a radio network controller functionality, a femtocell gateway functionality and a home eNodeB gateway functionality.

13. The method of claim 9, wherein the bearer for the data packets that are exchanged has one of a higher quality of service characteristic or a lower quality of service characteristic, wherein the bearer for the data packets that are exchanged has the higher quality of service characteristic responsive to the determination that the control signals relate to the first service and wherein the bearer for the data packets that are exchanged has the lower quality of service characteristic responsive to a determination that the control signals relate to the second service.

14. The method of claim 9, wherein the communicating of the control signals comprises universal mobile telecommunications system control signals and long term evolution control signals.

15. A machine-readable storage medium comprising executable instructions which, responsive to being executed by a system including a processor, cause the system to perform operations comprising:

communicating control information to a wireless access terminal, wherein the control information comprises information associated with one of mobility management processing, bearer management, or both of a mobile communication device in communication with the wireless access terminal;

determining whether the control information is related to a first service, that is one of a streaming media service or a voice over IP service, or a second service, that is different from the first service; and

coordinating an exchange of data, that is to or from the mobile communication device, between the wireless access terminal and an external packet data network, wherein the coordinating comprises providing a bearer, for the data that is exchanged, having a higher bandwidth characteristic selected from a group of bandwidth characteristics that include a lower bandwidth characteristic and the higher bandwidth characteristic, and wherein the bearer having the higher bandwidth characteristic is provided responsive to a determination that the control information relates to the first service.

16. The machine-readable storage medium of claim 15, wherein the operations further comprise communicating the data, wherein the communicating of the control information comprises a mobility management entity function and wherein the communicating of the data comprises a serving gateway function, each of the mobility management entity function and the serving gateway function comprising a respective core logic function of a common virtual machine.
