Abstract

A method of managing demand on a battery (26) of a mobile communications device (10) served by a network which defines a requirement relating to the behaviour of the mobile communications device (10), the method comprising assessing the status of the battery (26) and adjusting the behaviour of the mobile communications device (10) according to the status of the battery (26), such that the behaviour of the mobile communications device (10) departs from the network-defined requirement.

Claims

1. A method of managing demand on a battery of a mobile communications device served by a network which places a requirement on a behaviour of the mobile communications device, the method comprising:

assessing a status of the battery; and

adjusting the behaviour of the mobile communications device according to the status of the battery, such that the behaviour of the mobile communications device departs from the network-defined requirement.

2. A method according to claim 1, wherein assessing the status of the battery comprises assessing a level of charge of the battery.

3. A method according to claim 1, wherein assessing the status of the battery comprises assessing a rate of discharge of the battery.

4. A method according to claim 1, further comprising altering the operation of an ancillary function of the mobile communications device according to the status of the battery.

5. A method according to claim 1, further comprising altering the operation of a user experience related function of the mobile communications device according to the status of the battery.

6. A method of managing demand on a battery of a mobile communications device, the method comprising:

receiving, at a network serving the mobile communications device, an indication of a status of the battery of the mobile communications device; and

adjusting a requirement placed by the network on a behaviour of the mobile communications device according to the status of the battery so as to cause an adjustment to the behaviour of the mobile communications device.

7. A method of managing demand on a battery of a mobile communications device served by a network which places a requirement on a behaviour of the mobile communications device, the method comprising:

assessing a status of the battery; and

adjusting the behaviour of the mobile communications device according to the status of the battery so as to cause an adjustment to the network-placed requirement.

8. A method according to claim 7, wherein the mobile communications device alters a parameter that is transmitted to the network, which parameter is indicative of the capabilities of the mobile communications device, so as to cause an adjustment to the network-placed requirement.

9. A method according to claim 7, wherein the mobile communications device alters the number of antennae used by the mobile communications device, so as to cause an adjustment to the network-placed requirement.
