Extended QOS support in EPC

摘要

Example embodiments presented herein are directed towards a target Mobility Management Entity (MME) or a target Serving General Packet Radio Service Support Node (SGSN) network node, and method, for handling a mobility procedure or session procedure within the same operator. The roaming agreement handling may comprise comparing a Quality of Service (QoS) parameter associated with a source system, a maximum QoS associated with a target system and a Packet Data Network Gateway (PGW) or Policy and Changing Rules Function (PCRF) capability. The mobility procedure or session procedure handling may further comprise providing instructions for the roaming procedure based on the comparison.;Example embodiments may further comprise a Packet Data Network Gateway (PGW) network node, and method, for adjusting Quality of Service (QoS) during a mobility procedure or session procedure. The adjustment may be based on a received target maximum QoS.

1. A method in a target Mobility Management Entity (MME) or a target Serving General Packet Radio Service Support (SGSN) node for handling a mobility procedure or session procedure, the target MME node or the target SGSN node being comprised in a radio network, the method comprising:
receiving, from a source MME node or a source SGSN node, a communication message comprising a QoS parameter associated with a source serving network system, the communication message further comprising one of a Packet Data Network Gateway (PGW) or a Policy and Charging Rules Function (PCRF) capability information element, the capability information element indicating if at least one of a PGW and PCRF node supports maximum allowed QoS handling; comparing a maximum allowed QoS of a target serving network with the QoS parameter associated with the source serving network and the capability information element; and providing instructions to a source serving gateway (SGW) for the mobility procedure or session procedure for each Packet Data Network (PDN) connection associated with a requesting user equipment, the instructions being based the comparing.
