The invention provides real time dynamic resource management to improve end-to-end QoS by mobile devices regularly updating a resource availability server (RAS) with resource update information. Examples of resource update information are device battery status, available memory, session bandwidth, delay, packet loss, and jitter, network element storage capacity, network element processing power. This information is made available by the RAS. In addition, the RAS generates and maintains predictive models and makes available predictive data from these models. Network elements and devices retrieve this information in the form of notifications from the RAS or by way of querying the RAS. The network elements and devices, based on these predictions, act to negotiate sessions to optimise QoS. In one embodiment the RAS is updated by only mobile devices subscribed to the operator which hosts the RAS. The update information is addressed to the RAS as a stand-alone entity. However, it is envisaged that the server may be hosted by multiple operators and may receive updates from devices subscribed to different operators. Also, it is envisaged that not only mobile devices but also network elements such as MMSCs may send update information.

Network resource management

When a device is switched off, all messages for that device are stored in different distributed service centers. For example, the message from user A may be stored in SMSC A and a message from user B in SMSC B where both subscribers and respective SMSCs can even belong to different networks. When the device is switched on again it notifies its presence to the network (performed by the MSC indicating this to the HLR). As a result of this alert, different service centers that have messages pending for that device will be notified that the device has come on-line again (performed by the HLR notifying SMSC A and SMSC B). Instead of directly sending out all messages, as in the prior art, each service center instead schedules the messages in an internal queue for delivery according to a local control scheme, which achieves synchronized delivery from multiple distributed SMSCs even though there is no centralised control. Each service center maps the 'age' of the message on its time axis as the time-to-deliver the message to the device. The deliveries are then sent out according to the derived schedule. As independent service centers all will base their decisions on the same length of the delivery schedule and same maximum retention time, the message deliveries of the different service centers will be interleaved with one another. This ensures that for significant time differences, messages from different service centers will still arrive in order at the device.
