Abstract

An apparatus or method for transmitting data blocks on a communications channel having a radio link between two stations including a user equipment comprises receiving first data blocks from the user equipment, and transmitting second data blocks to the user equipment. A polling interval is dynamically set for the transmission of polling messages to the user equipment after transmission of the second data blocks, the polling interval being set in accordance with at least one of: a size of one or more data blocks received by the apparatus from the user equipment, a size of one or more blocks transmitted from the apparatus to the user equipment, and a service to which the user equipment is subscribed. The apparatus may be used as a PCU in a cellular mobile telephone system.

Claims

1. A method for performing communication between a user equipment and a network apparatus, comprising:

the user equipment transmitting first data blocks to the network apparatus;

the user equipment receiving second data blocks from the network apparatus;

the user equipment receiving one or more polling messages to request that the user equipment acknowledge receipt of transmitted data blocks, wherein the one or more polling messages are sent according to a polling interval dynamically set by the network apparatus after transmission of the second data blocks, wherein the polling interval is set responsive to at least one of;

a size of one or more data blocks received by the apparatus from the user equipment;

a size of one or more data blocks transmitted from the apparatus to the user equipment;

or

a service to which the user equipment is subscribed.

2. The method of claim 1, wherein the polling interval is set independently for each of a plurality of user equipments.

3. The method of claim 1, wherein the polling interval is set for a group of user equipments.

4. The method of claim 3, wherein the group of user equipments is defined by a subscription to a service.

5. The method of claim 1, wherein the polling interval is set further responsive to at least an estimated used transmission capacity value for a radio coverage area of a cellular radio network in which the network apparatus is located.

6. The method of claim 1, wherein the polling interval is set further according to a quality of service (QoS) profile associated with the user equipment.

7. The method of claim 1, wherein the polling interval is set further according to a parameter characterizing a quality level of signals received from the user equipment.

8. The method of claim 1, wherein the one or more polling messages comprise an acknowledgement polling message.

9. A user equipment configured to wirelessly communicate with a network apparatus, wherein the user equipment comprises:

one or more antennas for performing wireless communication; and

processing hardware coupled to the one or more antennas, wherein the processing hardware is configured to;

transmit first data blocks to the network apparatus using the one or more antennas;

receive second data blocks from the network apparatus using the one or more antennas; and

receive one or more polling messages to request that the user equipment acknowledge receipt of transmitted data blocks, wherein the one or more polling messages are sent according to a polling interval dynamically set by the network apparatus after transmission of the second data blocks, wherein the polling interval is set responsive to at least one of;

a size of one or more data blocks received by the apparatus from the user equipment;

a size of one or more data blocks transmitted from the apparatus to the user equipment;

or

a service to which the user equipment is subscribed.

10. The user equipment of claim 9, wherein the polling interval is set independently for each of a plurality of user equipments.

11. The user equipment of claim 9, wherein the polling interval is set for a group of user equipments.

12. The user equipment of claim 9, wherein the group of user equipments is defined by a subscription to a service.

13. The user equipment of claim 9, wherein the polling interval is set further responsive to at least an estimated used transmission capacity value for a radio coverage area of a cellular radio network in which the network apparatus is located.

14. The user equipment of claim 9, wherein the polling interval is set further according to a quality of service (QoS) profile associated with the user equipment.

15. The user equipment of claim 9, wherein the polling interval is set further according to a parameter characterizing a quality level of signals received from the user equipment.

16. The user equipment of claim 9, wherein the one or more polling messages comprise an acknowledgement polling message.
