Abstract

A user equipment, radio control node, method and computer program are disclosed. The user equipment is configured to communicate with other devices across a wireless communication network comprising a plurality of radio coverage cells, the user equipment being configured to respond to receipt of a message from the network, the message comprising a wait time, to not transmit a connection request until after expiry of the wait time; wherein the user equipment is configured during the wait time to receive paging requests from the network; and is configured to respond to at least some of the paging requests, the user equipment being configured to select the at least some of the paging requests to respond to in dependence upon paging information received from the network.

Claims

1. A user equipment, including a processor, configured to communicate with other devices across a wireless communication network comprising a plurality of radio coverage cells, said processor being configured to respond to receipt of a message from said network, said message comprising a wait time, to not transmit a connection request until after expiry of said wait time;

wherein said processor is configured to, during said wait time, receive paging requests from said network; and

is configured to respond to at least some of said paging requests, said processor being configured to select said at least some of said paging requests to respond to in dependence upon paging information received from said network; and

wherein said paging information comprises an indication of types of paging requests that must be responded to, said processor being configured to, during said wait time, respond to said types of paging requests that must be responded to.

2. The user equipment according to claim 1, said user equipment comprising a timer configured to indicate to said user equipment when said wait time has expired, said processor being configured when responding to said at least some paging requests to not reset said timer such that said timer is either paused or continues to time said wait time.

3. The user equipment according to claim 1, wherein said processor is configured to respond to at least some of said paging requests while continuing to run a wait time timer.

4. The user equipment according to claim 1, said user equipment being a machine type communication device and said wait time being an extended wait time of several minutes.

5. A user equipment, including a processor, configured to communicate with other devices across a wireless communication network comprising a plurality of radio coverage cells, said processor being configured to respond to receipt of a message from said network, said message comprising a wait time, to not transmit a connection request until after expiry of said wait time;

wherein said processor is configured to, during said wait time, receive paging requests from said network; and

is configured to respond to at least some of said paging requests, said processor being configured to select said at least some of said paging requests to respond to in dependence upon paging information received from said network; and

wherein said paging information is received as

a signal associated with said paging request indicating that said paging request must be responded to.

6. A network control node operable to control load across a wireless communication network comprising a plurality of radio coverage cells, said network control node comprising a processor configured to:

determine loading of at least one of said radio coverage cells based on an indication of an operating parameter of said at least one radio coverage cells;

receive connection requests from user equipment via said at least one of said radio coverage cells;

transmit a message in response to said processor determining said loading of said at least one of said radio coverage cells being above a predetermined level, said message comprising a wait time indicating a time during which said user equipment should not transmit a request to connect to said network;

transmit paging information indicating at least some paging requests that said user equipment should respond to during said wait time; and

determine said at least some paging requests that said user equipment should respond to in dependence upon a current loading of said at least one of said radio coverage cells determined by said processor.

7. The network control node according to claim 6, wherein the processor is further configured to transmit said paging information in said message comprising said wait time.

8. A network control node operable to control load across a wireless communication network comprising a plurality of radio coverage cells, said network control node comprising a processor configured to:

determine loading of at least one of said radio coverage cells based on an indication of an operating parameter of said at least one radio coverage cells;

receive connection requests from user equipment via said at least one of said radio coverage cells;

transmit a message in response to said processor determining said loading of said at least one of said radio coverage cells being above a predetermined level, said message comprising a wait time indicating a time during which said user equipment should not transmit a request to connect to said network;

transmit paging information indicating at least some paging requests that said user equipment should respond to during said wait time; and

transmit a system information broadcast, said system information broadcast comprising said paging information indicating said at least some paging requests that said user equipment should respond to during said wait time.

9. A method of selectively responding to paging requests at a user equipment during a wait time, said wait time arising in response to said user equipment having received a message comprising said wait time from a wireless communication network comprising a plurality of radio coverage cells, said wait time indicating a time during which said user equipment should not transmit a connection request;

the method comprising;

during said wait time, receiving at least one paging request from said network; and

responding to said paging request in dependence upon paging information received from said network;

wherein said paging information is received as

a signal associated with said paging request indicating that said paging request must be responded to.

10. A non-transitory computer-readable medium comprising a computer program which, when executed by a computer, control said computer to perform the method according to claim 9.

11. A method of controlling load across a wireless communication network comprising a plurality of radio coverage cells, comprising:

determining loading of at least one of said radio coverage cells;

receiving connection requests from user equipment via said at least one of said radio coverage cells;

transmitting a message in response to determining said loading of said at least one of said radio coverage cells being above a predetermined level, said message comprising a wait time indicating a time during which said user equipment should not transmit a connection request;

transmitting paging information indicating at least some paging requests that said user equipment should respond to during said wait time; and

transmitting a system information broadcast, said system information broadcast comprising said paging information indicating said at least some paging requests that said user equipment should respond to during said wait time.
