Abstract

Aspects of the subject disclosure include, for example, identifying a primary serving cell and a secondary serving cell, wherein the primary serving cell facilitates one of attachment, re-attachment or mobility, or any combination thereof, of a mobile device in association with coordination of a wireless service between the primary serving cell, the secondary serving cell and the mobile device. A latency value associated with a message exchange is determined between the primary and secondary serving cells via a messaging interface, and compared to latency requirements, which correspond to a group of mobile service features. A mobile service feature of the group is associated with the wireless service based on the comparison. The wireless service includes a coordinated exchange of wireless signals between the primary serving cell and the mobile device and between the secondary serving cell and the mobile device based on the mobile service feature. Other embodiments are disclosed.

First claim

What is claimed is:

1. A wireless access node, comprising:
a processing system including a processor; and
a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
comparing a latency value associated with message exchanges between a primary serving cell and a secondary serving cell of a mobile cellular network with a latency requirement for a mobile feature comprising a coordinated exchange of wireless signals between the primary serving cell and a mobile device and between the secondary serving cell and the mobile device; and
implementing the mobile feature responsive to the latency value meeting the latency requirement.

2. The wireless access node of claim 1 , wherein access to the mobile feature requires an exchange of information through the coordinated exchange.

3. The wireless access node of claim 2 , wherein the operations further comprise determining a demand for the mobile feature, wherein access by the mobile device to the mobile feature is based on the demand that is determined.

4. The wireless access node of claim 1 , wherein the operations further comprise identifying the primary serving cell and the secondary serving cell associated with the mobile cellular network.

5. The wireless access node of claim 1 , wherein the mobile feature includes Coordinated Multipoint transmission and/or reception (CoMP), Carrier Aggregation (CA) and Dual Carrier (DC), and wherein the latency requirement is less than one millisecond (1 ms) for one or more of CoMP, CA and DC.

6. The wireless access node of claim 1 , wherein the mobile feature includes coherent joint radio frequency transmissions from the primary serving cell and the secondary serving cell to the mobile device.

7. The wireless access node of claim 1 , wherein the mobile feature includes a dual connectivity between the primary serving cell, the secondary serving cell and the mobile device.

8. The wireless access node of claim 1 , wherein the mobile feature includes an aggregation of radio frequency carriers of the primary serving cell and the secondary serving cell.

9. The wireless access node of claim 8 , wherein the aggregation of the radio frequency carriers comprises a 3rd Generation Partnership Protocol, Long Term Evolution carrier aggregation.

10. A method, comprising:
comparing, by a processing system including a processor, a latency value associated with message exchanges between a primary serving cell and a secondary serving cell of a mobile cellular network with a latency requirement for a mobile feature comprising a coordinated exchange of wireless signals between the primary serving cell and a mobile device and between the secondary serving cell and the mobile device; and
implementing, by the processing system, the mobile feature responsive to the latency value meeting the latency requirement.

11. The method of claim 10 , wherein the mobile feature includes coherent joint radio frequency transmissions from the primary serving cell and the secondary serving cell to the mobile device, an aggregation of radio frequency carriers of the primary serving cell and the secondary serving cell, a dual connectivity between the primary serving cell, the secondary serving cell and the mobile device, or a combination thereof.

12. The method of claim 10 , wherein access to the mobile feature requires an exchange of information between the primary serving cell and the mobile device and between the secondary serving cell and the mobile device.

13. The method of claim 12 , wherein the exchange of information comprises transmitting wireless signals between the primary serving cell and the mobile device and between the secondary serving cell and the mobile device.

14. The method of claim 10 , further comprising determining a demand for the mobile feature and facilitating access by the mobile device to the mobile feature based on the demand that is determined.

15. The method of claim 10 , further comprising identifying the primary serving cell and the secondary serving cell associated with the mobile cellular network.

16. A non-transitory, machine-readable storage medium, comprising executable instructions of a wireless access device that, when executed by a processing system including a processor, facilitate performance of operations, comprising:
comparing a latency value associated with message exchanges between a primary serving cell and a secondary serving cell of a mobile cellular network with a latency requirement for a mobile feature comprising a coordinated exchange of wireless signals between the primary serving cell and a mobile device and between the secondary serving cell and the mobile device; and
implementing the mobile feature responsive to the latency value meeting the latency requirement.

17. The non-transitory, machine-readable storage medium of claim 16 , wherein access to the mobile feature requires an exchange of information between the primary serving cell and the mobile device and between the secondary serving cell and the mobile device.

18. The non-transitory, machine-readable storage medium of claim 17 , further comprising determining a demand for the mobile feature, wherein access by the mobile device to the mobile feature is based on the demand that is determined.

19. The non-transitory, machine-readable storage medium of claim 16 , wherein the operations further comprise identifying the primary serving cell and the secondary serving cell associated with the mobile cellular network.

20. The non-transitory, machine-readable storage medium of claim 16 , further comprising facilitating access, by the mobile device, to the mobile feature if the latency value does not exceed the latency requirement.
