Mitigation of radio interference and thermal issues using radio access technology selection
View Patent ↗A wireless UE device uses a method of radio technology and channel selection for transferring device traffic that includes detecting, at a wireless user equipment device, a condition related to at least one of temperature and radio interference and responsive to the detecting, determining to associate a data application on the wireless UE device with a radio access technology (RAT).
1. A method of radio technology and channel selection for transferring device traffic comprising:
detecting, at a wireless user equipment (UE) device, a condition caused by radio interference between multiple radios in the wireless UE device;
responsive to the detecting, sending a message from the wireless UE device to a network node using a first radio access technology (RAT) operating on a first frequency, wherein the message indicates the detected condition and a preferred second RAT or a preferred second frequency, the preferred second RAT is different than the first RAT, the preferred second frequency is different than the first frequency, and the first RAT and first frequency provide connectivity to the wireless UE device prior to detecting the condition;
receiving a response message from the network node, the response message instructing the wireless UE device to transfer device traffic to the preferred second RAT or to transfer the device traffic to the preferred second frequency; and
in response to receiving the response message, transferring the device traffic for a data application on the wireless UE device to the preferred second RAT or transferring the device traffic for the data application on the wireless UE device to the preferred second frequency.
2. The method of claim 1 , wherein the condition comprises the wireless UE device experiencing radio interference in a given access technology that is greater than a threshold value.
3. The method of claim 1 , wherein the condition further comprises one of opening an application or closing an application on the wireless UE device, the application requiring data transfer via a radio access technology.
4. The method of claim 1 , wherein the condition further comprises one of moving into a coverage area or moving out of a coverage area for a given radio access technology.
5. The method of claim 1 , further comprising receiving a measurement of a level of radio interference for the wireless user equipment (UE) device.
6. The method of claim 1 , wherein responsive to the detecting, the data application is moved from an association with a first one of a group consisting of a wireless local area network and a wide area cellular network to an association with a different one of the group.
7. The method of claim 1 , further comprising receiving, at the wireless UE device, a management object comprising at least one traffic routing rule.
8. The method of claim 7 , wherein the management object is received responsive to signaling a network node regarding the condition.
9. The method of claim 7 , wherein the wireless UE device is operable to override a subset of the at least one traffic routing rule.
10. The method of claim 9 , wherein the wireless UE device is operable to override the subset of the at least one traffic routing rule based on an override priority of each traffic routing rule in the subset.
11. The method of claim 1 , further comprising transferring device traffic for the data application to a radio access technology that is different than the preferred second RAT responsive to a new condition.
12. A wireless user equipment (UE) device, comprising:
a memory; and
at least one hardware processor communicatively coupled with the memory and configured to:
detect a condition caused by radio interference between multiple radios in the wireless UE device;
in response to detecting, send a message to a network node using a first radio access technology (RAT) operating on a first frequency, wherein the message indicates the detected condition and a preferred second RAT or a preferred second frequency, the preferred second RAT is different than the first RAT, the preferred second frequency is different than the first frequency, and the first RAT and first frequency provide connectivity to the wireless UE device prior to detecting the condition;
receive a response message from the network node, the response message instructing the wireless UE device to transfer device traffic to the preferred second RAT or to transfer the device traffic to the preferred second frequency; and
in response to receiving the response message, transfer the device traffic for a data application on the wireless UE device to the preferred second RAT or transferring the device traffic for the data application on the wireless UE device to the preferred second frequency.
13. The wireless UE device of claim 12 , the at least one hardware processor further configured to receive a management object comprising at least one traffic routing rule.
14. The wireless UE device of claim 13 , the at least one hardware processor further configured to override a subset of the at least one traffic routing rule.
15. The wireless UE device of claim 14 , the at least one hardware processor further configured to determine an order in which to override the subset of the at least one traffic routing rule based on an override priority assigned to each rule of the subset.
16. The wireless UE device of claim 13 , wherein the management object contains at least one set of linked traffic routing rules.
17. The wireless UE device of claim 12 , the at least one hardware processor further configured to transfer device traffic for the data application to a radio access technology that is different than the preferred second RAT responsive to a new condition.
