Method for improved overload protection in a telecommunication network, connection gateway entity for improved overload protection in a telecommunication network, telecommunication network, program and computer program product

摘要

The invention relates to a method for improved overload protection in a telecommunication network, wherein the telecommunication network is adapted to provide communication services to a plurality of user equipments, wherein any data transmission of payload data between the telecommunication network and any one of the plurality of user equipment requires at least one communication bearer to be established in association with the respective user equipment wherein a subset of user devices of the plurality of user devices is in a sleep mode or an inactive mode, the telecommunications network comprising a mobility management entity and a port gateway entity, the method comprising the steps of: receiving, from the port gateway An entity of a plurality of downlink data packets for the subset of user equipment of at least one packet data network, wherein the plurality of downlink data packets comprises a transmission of payload data using communication carriers, associating, by the telecommunications network, first traffic priority information to a first portion of the plurality of downlink data packets and second traffic priority information to a second portion of the plurality of downstream data packets, wherein the first traffic priority information is associated with a lower traffic priority than the second traffic priority information; Throttling, by the port gateway entity during a congestion time interval, first down data notification (DDN) requests to the mobility management entity, wherein the first down data notification (DDN) requests relate to the first portion of the plurality of downlink data packets with the first traffic priority information, - transmit , by the port gateway entity during the congestion time interval, of second down data notification (DDN) requests to the mobility v The second downlink data notification (DDN) request concerns the second part of the plurality of downlink data packets with the second traffic priority information, the first traffic priority information relating to at least one of the following: a first access point name (APN) used for the transmission of the first part of the Data packets to the port gateway entity is used, a first user location of a first user device of the subset of user devices, a combination of an Assignment / Maintenance Priority (ARP) level and a first traffic handling priority (THP), wherein the second traffic priority information relates to at least one of the following: a second access point name (APN) used for the transmission of the second part of the data packets to the port gateway entity, a second user location of a second user device of the subset of User equipment, - a combination of an Assignment / Maintenance Priority (ARP) level and a Second Traffic Handling Priority (THP).
