Abstract: A method, apparatus and computer program product receive a traffic redundancy indication from a user equipment in a communication network or from a policy controller. The method, apparatus and computer program product determine whether traffic redundancy is needed for the radio access network and the user plane function based on the traffic redundancy indication. The method, apparatus and computer program product request the radio access network to not establish redundancy mechanisms in a circumstance where traffic redundancy is not needed for the radio access network. The method, apparatus and computer program product request the user plane function to not establish redundancy mechanisms in a circumstance where traffic redundancy is not needed for the user plane function.

Abstract: A communication system includes a service responsible for sending signaling to a user equipment or an access network serving the user equipment. The service receives a request to send the signaling to the user equipment or the access network together with access type control information indicating whether the signaling is transmittable using any of a plurality of access types or a specific access type provided in the request. The service selectively forwards the signaling to the user equipment or the access network based on the access type control information.

Abstract: The apparatus includes a processor configured to send, over a 3rd Generation Partnership project (3GPP) access, a notifying message regarding non-3GPP access to a user equipment, the user equipment being simultaneously registered to the communication network via the 3GPP access and via the non-3GPP access, the user equipment being in a connection management-idle state over the non-3GPP access. The method includes sending over a 3rd Generation Partnership project (3GPP) access a notifying message regarding non-3GPP access to a user equipment, the user equipment being simultaneously registered to a communication network via the 3GPP access and via the non-3GPP access, the user equipment being in a connection management-idle state over the non-3GPP access.

Abstract: A method for Mobility Management MM in a system architecture supporting mobility between different access systems having separate Core Network CN-level MM entities while using common MM Area, the method comprising a step of: when a User Equipment UE leaves the coverage of a first one of the access systems where it is in a Non Radio Connected state as seen from Radio Access Network RAN, but seen in Connected State from CN-level MM entity, for the coverage of a second one of the access systems where it is in Idle state as seen from CN-level MM entity, putting the UE into Idle state as seen from CN-level MM entity of said first access system.
Abstract translation: 一种在支持在具有单独的核心网络CN级MM实体的不同接入系统之间的移动性的系统架构中的移动性管理MM的方法，同时使用公共MM区域，所述方法包括以下步骤：当用户设备UE离开第一个 在从无线电接入网RAN看到它处于非无线电连接状态的接入系统中，但是在CN级MM实体的连接状态中看到，对于处于空闲状态的第二接入系统的覆盖范围 如从CN级MM实体所见，将UE置于空闲状态，如从所述第一接入系统的CN级MM实体所见。
