Abstract:
The present disclosure relates to a technology for providing a service of effectively transmitting and receiving data by simultaneously using a 3GPP system and a non-3GPP system in a network in which the 3GPP system and the non-3GPP system coexist. A communication method of a non-3GPP access network entity according to embodiments of the present disclosure includes receiving overload status information from a gateway; receiving a session management request message from a user equipment (UE); and transmitting a session management reject message comprising a back-off timer to the UE. According to the embodiment of the present disclosure, when a specific PDN (or APN) is overloaded, the overload state can be controlled.
Abstract:
A handover method and apparatus for facilitating a handover of a user equipment to a femto cell in a wireless communication system supporting both the femto and macro cells. When a handover condition is detected, the user equipment acquires identity information of a target femto cell base station from system information transmitted by the target femto cell base station, decides whether to handover to the target femto cell base station, based on the identity information; and transmits a measurement report message including the identity information to a serving base station of the user equipment, when the handover is to be made.
Abstract:
The present invention relates to a method for controlling system overload in a wireless communication system. The method comprises: a first step in which a mobility management entity (MME) that has received a tracking region update request message from a first terminal transmits a location update request message to a home subscriber server (HSS); a second step in which, if the HSS has determined that a system overload has occurred, the HSS sets MME-backoff time for preventing the transmission of a request message to the HSS, and transmits a location update rejection message including said MME-backoff time to the MME; and a third step in which the MME drives a backoff timer corresponding to said MME-backoff time and rejects a TAU update request message from a terminal received prior to the completion of the driving of the backoff timer.
Abstract:
The present invention relates to a method and apparatus for managing a Local IP Access (LIP A) connection in a local network system. The method of managing a LIP A connection of UE in a connected state according to an embodiment of the present invention includes the steps of: a source home base station for UE determining a handover of the UE; when the handover of the UE is determined, determining whether a target home base station is a Long Term Evolution (LTE) release 10 or a Pre Rel-11 HeNB; and when the target home base station is a Pre Rel-11 HeNB, disconnecting the LIP A connection of the UE. According to an embodiment of the present invention, the mobility of UE having a LIPA PDN connection can be efficiently controlled in a local network where a Rel-11 H(e)NB and a Pre Rel-11 H(e)NB exist together.
Abstract:
The present invention relates to a method and a system for providing a sponsored service on an IMS-based mobile communication network, and comprises the steps of: a sponsored service client transmitting to a sponsored service server a sponsored service start request message; the sponsored service server determining the validity of the sponsored service after receiving the start request message; transmitting to the sponsored service client a sponsored service start acceptance message when the sponsored service server determines the sponsored service as valid; generating a sponsored service between the sponsored service client and an Internet service provider server; the sponsored service server generating charged fee information and transmitting the charged fee information to an authentication/authorization/accounting (AAA) server, when the sponsored service client requests termination of the sponsored service; and terminating the sponsored service session. According to the present invention, the sponsored service, in which a third parry Internet service provider can pay the cost using the mobile communication network instead of a wireless user equipment subscriber, can be provided, and the quality of the service can be dynamically controlled from the point the Internet service is provided.
