Method and apparatus for managing a wireless connection

1. An apparatus, comprising:

a radio transceiver;

at least one processing core configured to receive a first message;

the at least one processing core further configured to render the apparatus operable to monitor, while in a connected mode, for at least one of a timing drift and a potential cause of a timing drift; and

the at least one processing core further configured to, responsive to determining at least one of a timing drift and a potential cause of a timing drift, cause the radio transceiver to transmit at least one of a scheduling request and a message configured to initiate a random access procedure, wherein the apparatus determines to send either the scheduling request or the message configured to initiate the random access procedure based on a magnitude of a determined timing drift.

2. An apparatus according to claim 1 , wherein the apparatus comprises a mobile communication device.

3. An apparatus according to claim 1 , wherein a receiver is configured to receive the first message from a base station node.

4. An apparatus according to claim 1 , wherein the monitoring for a timing drift comprises monitoring at least one of downlink timing drift, relative downlink timing of different cells, discovery of a new cell, data from a sensor comprised in the apparatus and changes in a speed or location of the apparatus.

5. An apparatus according to claim 1 , wherein the apparatus is configured to initiate signaling toward a network, in case the apparatus determines it has data to send and where no timing drift was determined.

6. An apparatus according to claim 1 , wherein the apparatus is configured to suppress sending uplink control information during the monitoring.

7. An apparatus according to claim 1 , wherein the apparatus is configured to completely suppress sending uplink control information during the monitoring.

8. An apparatus, comprising:

at least one processor; and

at least one memory including computer program code

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following:

monitor a time alignment of a user equipment attached to a cell controlled by the apparatus;

responsive to determining that the time alignment of the user equipment changes less than a predefined threshold level of change, transmit a first message to the user equipment, wherein the first message is configured to cause the user equipment to begin monitoring for at least one of a timing drift and a potential cause of a timing drift.

9. A method in an apparatus, comprising:

monitoring a time alignment of a user equipment attached to a cell controlled by the apparatus;

responsive to determining that the time alignment of the user equipment changes less than a predefined threshold level of change, transmitting a first message to the user equipment, wherein the first message is configured to cause the user equipment to begin monitoring for at least one of a timing drift and a potential cause of a timing drift.

10. A method, comprising:

receiving a first message;

rendering an apparatus operable to monitor, while in a connected mode, at least one of a timing drift and a potential cause of a timing drift; and

responsive to determining at least one of a timing drift and a potential cause of a timing drift, transmitting at least one of a scheduling request and a message configured to initiate a random access procedure, wherein the apparatus determines to send either the scheduling request or the message configured to initiate the random access procedure based on a magnitude of a determined timing drift.

11. A method according to claim 10 , comprising receiving the first message from a base station node.

12. A method according to claim 10 , wherein the monitoring for a timing drift comprises monitoring at least one of downlink timing drift, relative downlink timing of different cells, discovery of a new cell, data from a sensor comprised in the apparatus and changes in a speed of the apparatus.

13. A method according to claim 10 , comprising initiating signaling toward a network responsive to a determination that there is data to send and where no timing drift was determined.

14. A computer program product comprising a non-transitory computer-readable medium bearing computer program code embodied therein for use with a computer, the computer program code comprising:

code for causing receiving a first message;

code for rendering an apparatus operable to monitor for at least one of a timing drift and a potential cause of a timing drift; and

code for responsive to determining a timing drift, transmitting at least one of a scheduling request and a message configured to initiate a random access procedure, wherein the apparatus determines to send either the scheduling request or the message configured to initiate the random access procedure based on a magnitude of a determined timing drift.
