Abstract

A wireless access node and media session extension method configured to extend a media session in a wireless network are provided. The wireless access node in one example embodiment includes a communication interface configured to exchange wireless communications with a user equipment (UE), a storage system configured to store a UE fail state corresponding to the UE of a current media session and store an extended dormancy time period, and a processing system coupled to the communication interface and to the storage system, with the processing system configured to obtain the UE fail state, if the UE fail state is true, then load the extended dormancy time period into a dormancy timer corresponding to the UE, and if the dormancy timer expires, then maintain one or both of a traffic channel and a signaling channel between the wireless access node and the UE.

First claim

What is claimed is:

1. A wireless access node configured to extend a media session in a wireless network, comprising:
a communication interface exchanges wireless communications with a user equipment (UE);
a storage system stores a UE fail state corresponding to the UE of a current media session and store an extended dormancy time period;
a processing system coupled to the communication interface and to the storage system, with the processing system determines if a media session initiation is completed,
if the media session initiation is completed, then the processing system compares a number of failed attempts to a predetermined session attempts limit and compare an elapsed time of the failed attempts to a predetermined session fail time period,
if the number of failed attempts exceeds the predetermined session attempts limit and if the elapsed time of the failed attempts is less than the predetermined session fail time period, then the processing system sets the UE fail state to true obtain the UE fail state,
if the UE fail state is true, then the processing system loads the extended dormancy time period into a dormancy timer corresponding to the UE, and if the dormancy timer expires, then the processing system maintains one or both of a traffic channel and a signaling channel between the wireless access node and the UE wherein the signaling channel exchanges signals with the wireless network to establish a connection and the traffic channel exchanges communications with the wireless network for the media session.

2. The wireless access node of claim 1 , with the processing system further, if the dormancy timer expires, drops at least one of a traffic channel and a signaling channel between the wireless access node and the UE.

3. The wireless access node of claim 1 , with the processing system further, if the dormancy timer expires, drops a traffic channel between the wireless access node and the UE while maintaining a signaling channel between the wireless access node and the UE.

4. The wireless access node of claim 1 , with the processing system further loads a default dormancy time period into the dormancy timer if the UE fail state is not true.

5. The wireless access node of claim 1 , with the storage system further stores a traffic level and a traffic level threshold and with the processing system further compares the traffic level to the traffic level threshold, maintain one or both of the signaling channel and the traffic channel if the traffic level does not exceed the traffic level threshold, and drop one or both of the signaling channel and the traffic channel if the traffic level exceeds the traffic level threshold.

6. The wireless access node of claim 1 , with the processing system further compares a UE current location to a UE top two locations, if the UE fail state is true and if the UE current location is within the UE top two locations, then load the extended dormancy time period into the dormancy timer, and load a default dormancy time period into the dormancy timer if the UE fail state is not true or if the UE current location is not within the UE top two locations.

7. A media session extension method in a wireless access node of a wireless network, comprising:
in the wireless access node, determining if a media session initiation is completed, and if the media session initiation is completed, then comparing a number of failed attempts to a predetermined session attempts limit and comparing an elapsed time of the failed attempts to a predetermined session fail time period;
in the wireless access node, if the number of failed attempts exceeds the predetermined session attempts limit and if the elapsed time of the failed attempts is less than the predetermined session fail time period, then setting a User Equipment (UE) fail state corresponding to the UE of a current media session to true;
in the wireless access node, if the UE fail state is true, then loading an extended dormancy time period into a dormancy timer corresponding to the UE; and
in the wireless access node, if the dormancy timer expires, then maintaining one or both of a traffic channel and a signaling channel between the wireless access node and the UE wherein the signaling channel exchanges signals with the wireless network to establish a connection and the traffic channel exchanges communications with the wireless network for the media session.

8. The media session extension method of claim 7 , further comprising, in the wireless access node, if the dormancy timer expires, dropping at least one of a traffic channel and a signaling channel between the wireless access node and the UE.

9. The media session extension method of claim 7 , further comprising, in the wireless access node, if the dormancy timer expires, dropping a traffic channel between the wireless access node and the UE while maintaining a signaling channel between the wireless access node and the UE.

10. The media session extension method of claim 7 , further comprising, in the wireless access node, loading a default dormancy time period into the dormancy timer if the UE fail state is not true.

11. The media session extension method of claim 7 , further comprising:
in the wireless access node, comparing the traffic level to the traffic level threshold;
in the wireless access node, maintaining one or both of the signaling channel and the traffic channel if the traffic level does not exceed the traffic level threshold; and
in the wireless access node, dropping one or both of the signaling channel and the traffic channel if the traffic level exceeds the traffic level threshold.

12. The media session extension method of claim 7 , further comprising:
in the wireless access node, comparing a UE current location to a UE top two locations;
in the wireless access node, if the UE fail state is true and if the UE current location is within the UE top two locations, loading the extended dormancy time period into the dormancy timer; and
in the wireless access node, if the UE fail state is not true or if the UE current location is not within the UE top two locations, loading a default dormancy time period into the dormancy timer.

13. A media session extension method in a wireless access node of a wireless network, comprising:
in the wireless access node, determining if a media session initiation is completed, and if the media session initiation is completed, then comparing a number of failed attempts to a predetermined session attempts limit and comparing an elapsed time of the failed attempts to a predetermined session fail time period;
in the wireless access node, if the number of failed attempts exceeds the predetermined session attempts limit and if the elapsed time of the failed attempts is less than the predetermined session fail time period, then setting a User Equipment (UE) fail state corresponding to a UE of a current media session to true;
in the wireless access node, if the UE fail state is true and if the UE is within a UE top two locations, then loading an extended dormancy time period into a dormancy timer corresponding to the UE; and
in the wireless access node, if the dormancy timer expires, then maintaining one or both of a traffic channel and a signaling channel between the wireless access node and the UE wherein the signaling channel exchanges signals with the wireless network to establish a connection and the traffic channel exchanges communications with the wireless network for the media session.

14. The media session extension method of claim 13 , further comprising, in the wireless access node, if the dormancy timer expires, dropping at least one of a traffic channel a
