Arrangements and method relating to communication bearers

A method for handling repetitive transfer of information in a network node for a mobile network supporting communication of information, the network node comprising a bearer service handler, wherein the method comprises the steps of:

• handling, by a bearer service manager, a first additional bearer service attribute comprising information about a time period between at least two consecutive information transfer events,
• handling, by the bearer service manager, a second additional bearer service attribute comprising information relating to the amount of data to be transferred during at least one of said at least two consecutive information transfer events,
• activating, by the bearer service manager, a bearer service adapted to handle repetitive information transfer at a first transfer event;
• deactivating, by the bearer service manager, an activated repetitive bearer service and releasing the repetitive bearer service resources when a respective information transfer event ends;
• and
• reactivating or re-establishing the respective bearer service resources at or before initiation of a subsequent information transfer event,
• wherein the reactivating or re-establishing of the respective bearer service resources is triggered by lapsing of a timer set to said time period of the first additional bearer service attribute, and
• wherein the bearer service handler supports one or more bearer services, each defined by a number of attributes, and comprising the bearer service manager configured to control enablement, modification and maintenance of bearer services with particular QoSs, a resource handler configured to distribute resources between bearer services requesting transfer of information, an attribute handler configured to handle bearer service attributes and/or QoS attributes or QoS profile for one or more traffic classes, and an admission controller configured to control and hold information about bearer service resource allocation.
