    Abstract: A method for identifying whether a selective internet protocol transport opportunity (SIPTO) route is allowed to be used by at least one wireless communication unit comprises, at a core network element: storing subscription profile data associated with the at least one wireless communication unit in a home subscriber server (HSS) database, where the subscription profile data comprises an indication of whether the wireless communication unit has access rights to use a SIPTO route, and generating a SIPTO indicator for informing at least one network element that the at least one wireless communication unit is allowed to use the SIPTO route.

    Abstract: The present disclosure relates to a communication method and device in a wireless communication system supporting network slicing, and, according to an embodiment of the present disclosure, a method performed by a terminal in a wireless communication system supporting network slicing comprises steps in which: a terminal transmits a session establishment request message for a first network slice through a first access network; a session establishment rejection message is received through the first access network from a network entity for managing a session for the first network slice; and handover to a second access network, which is the preferred access network of the terminal, is determined if the session establishment rejection message includes, as the cause of rejection of the session establishment request, information that indicates the number of sessions exceeding the maximum number of sessions for the first network slice.

    Abstract: A method of routing multicast traffic, suitable for use in a network comprising a router node connected to a first data network and to a second data network, the router node having a capability to route multicast traffic from the first and second data networks to a user equipment, is provided. The method comprises: receiving a first message from the user equipment at the router node, the first message requesting membership of a first multicast group having a first multicast address; and inhibiting receipt of multicast traffic having the first multicast address from at least the second data network by the user equipment, dependent upon a determination as to whether the first message may relate to a multicast address in the first network.

    Abstract translation: 一种适用于包括连接到第一数据网络和第二数据网络的路由器节点的网络中的多播业务的路由方法，所述路由器节点具有将来自第一和第二数据网络的多播业务路由到用户的能力 设备。 该方法包括：在路由器节点处从用户设备接收第一消息，第一消息请求具有第一多播地址的第一多播组的成员资格; 以及取决于关于第一消息是否可能与第一网络中的多播地址有关的确定，禁止用户设备从至少第二数据网络接收具有第一多播地址的多播业务。

    Abstract: The present invention relates to a terminal and communication method of the same. According to an embodiment, a method performed by a proxy call session control function, P-CSCF, in a wireless communication system, may include: receiving, from a remote terminal, a first message including first information indicating that the remote terminal accesses through a relay terminal; determining a policy and charging rules function, PCRF, serving a relay connection associated with the relay terminal; and transmitting, to the determined PCRF, a second message for requesting the determined PCRF to validate service information associated with the remote terminal. The first message may further include a utran-cell-id-3gpp parameter, the utran-cell-id-3gpp parameter including public land mobile network, PLMN, information and E-UTRAN cell identity, ECI.
