Abstract

Some examples herein can permit increasing the number of concurrent sessions that a network can support. An anchoring network device can anchor the sessions. A network gateway can transcode data of those sessions using transcoding units, and determine a utilization of the transcoding units. The anchoring network device can determine that the utilization satisfies a load criterion. The anchoring network device can adjust capability information of at least one session to reduce load on the network gateway. In some examples, the anchoring network device can send a session-change message to terminal(s) of session(s). In some examples, the anchoring network device can remove a relatively high-load codec from a codec list of a session. In some examples, the anchoring network device can adjust capability information based on predicted load.

Dependent claims

A network gateway system, comprising:

a network interface;
a plurality of transcoding units configured to transcode data between at least two codecs;
and
a control unit configured to:
anchor at least two communication sessions via the network interface, wherein a first communication session of the at least two communication sessions is associated with at least two terminals;
operate individual transcoding units of the plurality of transcoding units to transcode data of the first communication session between the at least two codecs associated with the at least two terminals;
determine, based at least on a transcoding load associated with the plurality of transcoding units, a utilization of the plurality of transcoding units, wherein the transcoding load comprises a transcoding resource density associated with the at least two codecs of the first communication session that indicates a number of transcoding units available for the at least two codecs;
determine that the utilization satisfies a predetermined load criterion associated with the plurality of transcoding units;
generate, based at least on the utilization satisfying the predetermined load criterion, an updated codec list that identifies permitted codecs for the plurality of transcoding units;
and
adjust, based at least on the updated codec list, capability information of the first communication session to reduce a load on the network gateway system by modifying the at least two codecs associated with the first communication session.
