UE, ANDSF, mobile communication system, PGW, and communication method

摘要

UE receives a mobile operator policy including flow identification information, access system identification information, and a degree of compulsion from an ANDSF, and in a case where the degree of compulsion included in the mobile operator policy is a degree of compulsion that compels the UE to perform switching, transmits a request to forcibly switch a communication path used flow communication corresponding to the flow identification information to an access system corresponding to the access system identification information included in the mobile operator policy. As a result, by transmitting an MO policy from the ANDSF to the UE while the UE connected to a first access system is performing data communication, the UE changes a UE policy to the MO policy, thereby providing a mobile communication system or the like that is capable of avoiding concentration of traffic in the first access system.

主权项

1. UE (User Equipment) in a mobile communication system including a PGW (Packet Data Network Gateway), the UE that establishes, with the PGW, a communication path using a first access system and a communication path using a second access system, and an ANDSF (Access Network Discovery and Selection Function) that transmits a mobile operator policy to the UE, the UE comprising:
receiving the mobile operator policy including flow identification information, access system identification information, and a degree of compulsion from the ANDSF; and transmitting, in a case where the degree of compulsion included in the mobile operator policy is a degree of compulsion that compels the UE to perform switching, a request to switch a communication path used for flow communication corresponding to the flow identification information to an access system corresponding to the access system identification information included in the mobile operator policy.
