Abstract

A wireless communication recovery method and a corresponding communication device are described. In the wireless communication recovery method, a connection failure of a radio access technology (RAT) is detected. Further, the detected connection failure is categorized based on a network level at which the connection failure has occurred. The RAT at the corresponding network level is then disabled for a time period based on the categorization of the connection failure and service in the RAT is recovered based on thresholds for the categorized failure levels.

First claim

What is claimed is:

1. A wireless communication recovery method of a communication device, the method comprising:
detecting a connection failure of a radio access technology (RAT) between the communication device and a network entity;
categorizing the detected connection failure based on a network level that includes the network entity at which the connection failure has occurred; and
disabling the RAT for a time period at the network level that corresponds to the category of the connection failure that includes the network entity to block communications during the time period between the communication device and the network entity,
wherein the category associated with the connection failure includes a tier of network entities associated with operation within a communication network.

2. The wireless communication recovery method of claim 1 , wherein the categorizing the connection failure comprises:
determining the network level that includes the network entity at which the connection failure has occurred; and
categorizing the detected connection failure based on the determined network level.

3. The wireless communication recovery method of claim 1 , wherein the network level that includes the network entity comprises at least one of:
a serving cell network level;
a tracking area network level; and
a communication network level.

4. The wireless communication recovery method of claim 1 , wherein disabling the RAT at the corresponding network level that includes the network entity comprises disabling the RAT only for a cell serving the communication device.

5. The wireless communication recovery method of claim 1 , wherein disabling the RAT at the corresponding network level that includes the network entity comprises disabling the RAT only for a tracking area of a cell serving the communication device.

6. The wireless communication recovery method of claim 1 , wherein disabling the RAT at the corresponding network level that includes the network entity comprises disabling the RAT only for a public land mobile network (PLMN) area of a cell serving the communication device.

7. The wireless communication recovery method of claim 1 , wherein the time period is determined based on a timer initiated in response to the connection failure being one of consecutive connection failures, and wherein the connection failure has exceeded a predetermined failure threshold.

8. The wireless communication recovery method of claim 1 , wherein the connection failure is a Random Access Channel (RACH) failure and the network level is a serving cell of the RAT.

9. The wireless communication recovery method of claim 1 , wherein the connection failure is a temporary network rejection and the network level that includes the network entity is a tracking area of a serving cell.

10. The wireless communication recovery method of claim 1 , wherein the connection failure is a temporary network rejection and the network level that includes the network entity is a public land mobile network (PLMN) area of a serving cell.

11. A communication device operable to perform a wireless communication recovery operation, the communication device comprising:
a transceiver configured to communicate via a radio access technology (RAT); and
a controller configured to:
detect a connection failure of the RAT between the communication device and a network entity;
categorize the detected connection failure based on a network level that includes the network entity at which the connection failure has occurred; and
disable the RAT for a time period at the network level that corresponds to the category of the connection failure that includes the network entity to block communications during the time period between the communication device and the network entity,

wherein the time period is determined based on a timer initiated in response to the connection failure being one of consecutive connection failures, and wherein the connection failure has exceeded a predetermined failure threshold.

12. The communication device of claim 11 , wherein the controller is configured to:
determine the network level that includes the network entity at which the connection failure has occurred; and
categorize the detected connection failure based on the determined network level.

13. The communication device of claim 11 , wherein the network level that includes the network entity comprises at least one of:
a serving cell network level;
a tracking area network level; and
a communication network level.

14. The communication device of claim 11 , wherein disabling the RAT at the corresponding network level that includes the network entity comprises disabling the RAT for only a cell serving the communication device.

15. The communication device of claim 11 , wherein disabling the RAT at the corresponding network level that includes the network entity comprises disabling the RAT for only a tracking area of a cell serving the communication device.

16. The communication device of claim 11 , wherein disabling the RAT at the corresponding network level that includes the network entity comprises disabling the RAT for only a public land mobile network (PLMN) of a cell serving the communication device.

17. The communication device of claim 11 , wherein the controller is configured to set the time period of the timer based on timer information stored within a memory of the communication device.

18. The communication device of claim 11 , wherein the connection failure is a Random Access Channel (RACH) failure and the network level that includes the network entity is a serving cell of the RAT.

19. The communication device of claim 11 , wherein the connection failure is a temporary network rejection and the network level that includes the network entity is a tracking area of a serving cell.

20. The communication device of claim 11 , wherein the connection failure is a temporary network rejection and the network level that includes the network entity is a public land mobile network (PLMN) area of a serving cell.

21. A wireless communication recovery method of a communication device, the method comprising:
detecting a connection failure of a radio access technology (RAT) between the communication device and one of a plurality of network entities;
categorizing the detected connection failure as: (i) a first connection failure type in response to the connection failure occurring at a first network level that includes a first one of the plurality of network entities at which the connection failure has occurred, the first network level being associated with a first cell coverage area, and (ii) a second connection failure type in response to the connection failure occurring at a second network level that includes a second one of the plurality of network entities at which the connection failure has occurred, the second network level being associated with a second cell coverage area, the second cell coverage area being greater than the first cell coverage area; and
blocking, at the first network level or the second network level, communications during a time period between the communication device and one or more of the plurality of network entities included in the first network level or second level by:
when the detected connection failure is categorized as the first connection failure type, disabling the RAT during the time period at the first network level; and
when the detected connection failure is categorized as the second connection failure type, disabling the RAT d
