One or more packets associated with a wakeup event for a mobile user device is/are delayed, thereby extending the duration of the wakeup event. Because the duration of the wakeup event is extended, the start of the next wakeup event for the mobile user device is delayed by a time interval, and therefore the signaling load on the mobile network is reduced during this time interval compared to the signaling load that would have been on the mobile network if the start of the next wakeup event had not been delayed. If the delayed packet(s) is/are data packet(s), then the disclosure presents a solution which involves data to solve a problem relating to signaling.

Reducing signaling load on a mobile network

A method for communication includes monitoring communication traffic in a wireless data network that serves wireless communication terminals. Control messages, relating to setting-up of voice calls over the wireless data network for the wireless communication terminals, are identified in the communication traffic. Precedence is given to the identified control messages, relative to other communication traffic that is not related to setting-up of voice calls. The communication traffic is controlled selectively in accordance with the precedence.

Efficient processing of voice-over-LTE call setup

A method includes, in a wireless data network, monitoring communication conditions at an intermediate location between a wireless communication terminal and a network element that provides voice-call services over the network to the wireless communication terminal. Upon detecting that the communication conditions are expected to cause the wireless communication terminal to send a notification to the network element, an early notification is sent to the network element on behalf of the terminal. Another method includes detecting a notification in which a terminal notifies a network element of degraded reception performance. A modification, which the network element is expected to perform in a transmission characteristic to the terminal in response to the notification, is predicted. In-flight communication traffic, which is en-route to the terminal and whose transmission characteristic is not yet modified in response to the notification, is intercepted. The predicted modification is applied to the in-flight communication traffic.

Proxy schemes for voice-over-LTE calls

A method, a computer readable medium and a policy enforcer, the policy enforcer may include: multiple pairs of interfaces; multiple data blades; a switch; at least one load balancing circuit; wherein each pair of interfaces is located along a path between a RAN and an external network through which information packets should have propagated at an absence of the policy enforcer; wherein the at least one load balancing circuit is arranged to select, for each information packet, a selected policy enforcing processor; wherein the at least one load balancing circuit is arranged to select is arranged to send each information packet over the switch to a selected policy enforcing processor; wherein each selected policy enforcing processor is arranged to perform a policy enforcing operation on each information packet associated with the selected policy enforcing processor.
