A system, method and computer-readable medium for allowing the use of an alternative numbering plan for delivering short messages to mobile subscribers using the public mobile telephone network is provided. Users of an enterprise or other closed networks as well as users that are not part of a closed network may send short messages destined to members of an enterprise or closed network from their mobile or other devices associated with their subscription using an alternative enterprise directory number, such as the office number, instead of the mobile number, such that the alternative number will be presented at the destination device as the originating number. The recipient may respond to the message by addressing the response to the enterprise or closed network number, and the response may be delivered to the originator's mobile or other device associated with their subscription.

An apparatus comprising means for receiving, by an integrated access backhaul node from an integrated access backhaul donor, information for limiting re-routing of data packets over one or more wireless backhaul connections of an integrated access backhaul network; means for receiving, by the integrated access backhaul node, at least one data packet over a first wireless backhaul connection from an originating integrated access backhaul node; means for re-routing, by the integrated access backhaul node, the received at least one data packet over a second wireless backhaul connection based on the received information for limiting re-routing.

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Disclosed is a method of fault recovery in a multi-hop network having a plurality of nodes, defining a route, comprising the steps of: determining that a fault exists between two of the plurality of nodes (B, C); performing a hierarchical fault recovery process.

Aspects described herein relate to receiving, over a sub-channel of multiple sub-channels, ultra-reliable quality-of-service (QoS) traffic from one or more UEs over a time duration wherein other sub-channels of the multiple sub-channels are used for initial ultra-reliable QoS transmissions from one or more other transmitting UEs over the time duration, and relaying, along with one or more other relaying UEs, the ultra-reliable QoS traffic over a subsequent time duration.

Method and apparatus for application server change are disclosed. A method comprises obtaining information on application server change for an application when server changes to a target application server; and making decision to inform UE to rediscover the target application server for the application or configure UPF to steer traffic to and from the target application server for the application
