Abstract

A system and method for improving the user experience with a mobile wireless device by reconnecting to a faster speed connection after being rejected for the higher speed by an overloaded cell before expiration of a de-prioritization timer when the mobile wireless device travels away from the overloaded cell. In an embodiment, a method includes receiving from the first cell a connection rejection instructing the mobile wireless device to de-prioritize one or more frequencies of the first connection technology and a de-prioritization timer indicating a time period for the frequencies to remain de-prioritized; determining that the mobile wireless device has left the coverage area of the first cell; and connecting to a second cell of the telecommunication network via a connection in the one or more frequencies of the first connection technology prior to the expiration of the de-prioritization timer.

First claim

What is claimed is:

1. A method performed by a mobile wireless device, comprising:
transmitting, by the mobile wireless device, a request to connect to a first cell;
receiving, by the mobile wireless device, an indication to de-prioritize one or more frequencies, of a first connection frequency range, used to connect to the first cell, the indication indicating a time period for the one or more frequencies to remain de-prioritized;
determining, by the mobile wireless device, that the mobile wireless device has left a coverage area of the first cell and entered into a coverage area of a second cell prior to an expiration of the time period, and based on the determination, clearing a de-prioritization of the one or more frequencies, the first cell and the second cell being in an equivalent network; and
connecting, by the mobile wireless device, to the second cell via a non de-prioritized connection using one of the one or more frequencies.

2. The method of claim 1 , further comprising:
connecting, by the mobile wireless device, to the first cell via a second connection of a second connection frequency range prior to expiration of the time period.

3. The method of claim 1 , wherein determining that the mobile wireless device has left the coverage area of the first cell comprises a determination of M consecutive different cell changes, M consecutive reselections, M consecutive handovers, or M consecutive base station (BS) changes, wherein M is a predefined integer.

4. The method of claim 1 , wherein determining that the mobile wireless device has left the coverage area of the first cell comprises determining a geographical region (GEO) change.

5. The method of claim 1 , further comprising connecting via a first connection frequency range responsive to a determination of a registration zone change, a routing area change, a location area change, a system identification number (SID) change, or a network identification number (NID) change.

6. The method of claim 1 , further comprising:
receiving a detection criteria from the first cell, wherein determining that the mobile wireless device has left the coverage area of the first cell comprises determining that the mobile wireless device has left the coverage area of the first cell according to the detection criteria received from the first cell.

7. The method of claim 1 , wherein the time period is a first time period, the method further comprising:
connecting via the first connection frequency range responsive to a determination that the mobile wireless device has left the coverage area of the first cell and a determination that a second time period has expired; and
refraining from connecting via the first connection frequency range and clearing a second timer associated with the second time period responsive to a determination that the mobile wireless device travels back to an area covered by the first cell prior to expiration of the second time period.

8. A mobile wireless device, comprising:
a non-transitory memory storage comprising instructions; and
a processor in communication with the non-transitory memory storage, wherein the processor executes the instructions to:
transmit a request to connect to a first cell;
receive an indication to de-prioritize one or more frequencies, of a first connection frequency range, used to connect to the first cell, the indication indicating a de-prioritization time period for the one or more frequencies to remain de-prioritized;
determine that the mobile wireless device has left a coverage area of the first cell and entered into a coverage area of a second cell prior to an expiration of the de-prioritization time period, and based on the determination, clearing a de-prioritization of the one or more frequencies, the first cell and the second cell being in an equivalent network; and
connect to the second cell via a non de-prioritized connection using one of the one or more frequencies.

9. The mobile wireless device of claim 8 , wherein the processor executes the instructions to:
connect to the first cell via a second connection of a second connection frequency range prior to expiration of the de-prioritization time period.

10. The mobile wireless device of claim 8 , wherein the processor executes the instructions to determine that the mobile wireless device has left the coverage area of the first cell comprises a determination of M consecutive different cell changes, M consecutive reselections, M consecutive handovers, or M consecutive base station (BS) changes, wherein M is a predefined integer.

11. The mobile wireless device of claim 8 , wherein the processor executes the instructions to determine that the mobile wireless device has left the coverage area of the first cell comprises a determination of a geographical region (GEO) change.

12. The mobile wireless device of claim 8 , wherein the processor executes the instructions to connect, via the first connection frequency range responsive to a determination of a registration zone change, a routing area change, a location area change, a system identification number (SID) change, or a network identification number (NID) change.

13. The mobile wireless device of claim 8 , wherein the processor executes the instructions to:
receive a detection criteria from the first cell, wherein determining that the mobile wireless device has left the coverage area of the first cell comprises determining that the mobile wireless device has left the coverage area of the first cell according to the detection criteria received from the first cell.

14. The mobile wireless device of claim 8 , wherein the de-prioritization time period is a first de-prioritization time period, and wherein a first de-prioritization timer is associated with the first de-prioritization time period, the processor executes the instructions to:
connect via the first connection frequency range responsive to a determination that the mobile wireless device has left the coverage area of the first cell and a determination that a second de-prioritization time period has expired; and
refrain from connecting via the first connection frequency range and clearing a second de-prioritization timer associated with the second de-prioritization time period responsive to a determination that the mobile wireless device travels back to an area covered by the first cell prior to expiration of the second de-prioritization time period.

15. A non-transitory computer-readable media storing computer instructions for execution in a mobile wireless device, that when executed by one or more processors, cause the one or more processors to perform the steps of:
transmitting a request to connect to a first cell;
receiving an indication to de-prioritize one or more frequencies, of a first connection frequency range, used to connect to the first cell, the indication indicating a de-prioritization time period for the one or more frequencies to remain de-prioritized;
determining that the mobile wireless device has left a coverage area of the first cell and entered into a coverage area of a second cell prior to an expiration of the de-prioritization time period, and based on the determination, clearing a de-prioritization of the one or more frequencies, the first cell and the second cell being in an equivalent network; and
connecting to the second cell via a non de-prioritized connection using one of the one or more frequencies.

16. The non-transitory computer-readable media of claim 15 , wherein the instructions further comprise instructions that cause the one or more processors to perform the step of:
connecting to the fi
