Abstract

Devices, systems, articles of manufacture, and methods for allowing a rejected wireless communication device access to a communication channel are described. According to some embodiments, a message that includes a wait state override indicator is generated. The message is transmitted to the wireless communication device. A communication channel is established with the wireless communication device based on the wait state override indicator. Other aspects, embodiments, and features are also claimed and described.

First claim

We claim:

1. A method for establishing a communication channel with a wireless communication device that is a machine type communication (MTC) device, the method comprising:
receiving, at a base station, a first channel request from the wireless communication device;
transmitting, in response to the first channel request, an assignment reject message to the wireless communication device that comprises a wait state time period and is configured to place the wireless communication device into a wait state for the wait state time period;
generating a message that comprises a wait state override indicator in response to receiving an indication that the wait state of the wireless communication device needs overriding to allow communication with the wireless communication device, wherein the message is generated in response to reception of an urgent information message that comprises the wait state override indicator, the urgent information message initiated at a server outside a radio access network (RAN);
transmitting the message to the wireless communication device; and
establishing a communication channel with the wireless communication device based on the wait state override indicator.

2. The method of claim 1 , further comprising receiving a second channel request from the wireless communication device, wherein the second channel request was made in response to the message.

3. The method of claim 2 , wherein the second channel request is received via an access channel.

4. The method of claim 1 , wherein the wireless communication device is in the wait state when the message is transmitted to the wireless communication device, and wherein channel requests cannot be transmitted by the wireless communication device unless the wait state is overridden.

5. The method of claim 4 , wherein the message is transmitted prior to expiration of the wait state of the wireless communication device.

6. The method of claim 4 , wherein the message is transmitted after expiration of the wait state of the wireless communication device.

7. The method of claim 1 , wherein the message comprises a paging message.

8. The method of claim 1 , wherein the wireless communication device can operate autonomously to initiate establishment of a communication channel.

9. The method of claim 1 , wherein the method is performed by the base station, and wherein the wireless communication device is a machine type communication device.

10. The method of claim 1 , wherein the wait state override indicator in the message is transmitted to more than one wireless communication device.

11. An apparatus for establishing a communication channel with a wireless communication device that is a machine type communication (MTC) device, comprising:
a processor;
memory in electronic communication with the processor; and
instructions stored in the memory, the instructions being executable by the processor to:
receive, at a base station, a first channel request from the wireless communication device;
transmit, in response to the first channel request, an assignment reject message to the wireless communication device that comprises a wait state time period and is configured to place the wireless communication device into a wait state for the wait state time period
generate a message that comprises the wait state override indicator in response to receiving an indication that a wait state of the wireless communication device needs overriding to allow communication with the wireless communication device, wherein the message is generated in response to reception of an urgent information message that comprises the wait state override indicator, the urgent information message initiated at a server outside a radio access network (RAN);
transmit the message to the wireless communication device; and
establish a communication channel with the wireless communication device based on the wait state override indicator.

12. The apparatus of claim 11 , further comprising instructions executable to receive a second channel request from the wireless communication device, wherein the second channel request was made in response to the message.

13. The apparatus of claim 12 , wherein the second channel request is received via an access channel.

14. The apparatus of claim 11 , wherein the wireless communication device is in the wait state when the message is transmitted to the wireless communication device, and wherein channel requests cannot be transmitted unless the wait state is overridden.

15. The apparatus of claim 14 , wherein the message is transmitted prior to expiration of the wait state of the wireless communication device.

16. The apparatus of claim 14 , wherein the message is transmitted after expiration of the wait state of the wireless communication device.

17. The apparatus of claim 11 , wherein the message comprises a paging message.

18. The apparatus of claim 11 , wherein the wireless communication device can operate autonomously to initiate establishment of a communication channel.

19. The apparatus of claim 11 , wherein the apparatus is a base station, and wherein the wireless communication device is a machine type communication device.

20. The apparatus of claim 11 , wherein the wait state override indicator in the message is transmitted to more than one wireless communication device.

21. A method for establishing a communication channel by a wireless communication device that is a machine type communication (MTC) device, the method comprising:
transmitting a first channel request to a wireless communication system;
receiving an assignment reject message, that comprises a wait state time period, from the wireless communication system in response to the first channel request;
entering a wait state for the wait state time period based on the assignment reject message;
receiving a message from the wireless communication system, wherein the message is generated in response to an urgent information message that comprises the wait state override indicator, the urgent information message initiated at a server outside a radio access network (RAN);
determining from the message that the wait state is to be overridden; and
attempting to establish a communication channel with the wireless communication system based on the message.

22. The method of claim 21 , wherein attempting to establish a communication channel comprises transmitting a second channel request on an access channel in response to the message.

23. The method of claim 21 , further comprising waiting in the wait state, wherein channel requests cannot be transmitted unless the wait state is overridden.

24. The method of claim 21 , wherein the message comprises a paging message, wherein the message comprises a wait state override flag, and wherein determining that a wait state is to be overridden comprises determining that the value of the wait state override flag indicates that the wait state is to be overridden.

25. The method of claim 21 , further comprising returning to the wait state after completion of information exchange related to wait state override.

26. The method of claim 21 , wherein the wireless communication device can operate autonomously to initiate establishment of a communication channel.

27. The method of claim 21 , wherein the wireless communication device is a machine type communication device, and wherein the wireless communication system is a
