Methods, apparatus, and systems for providing multicast handover are disclosed. In one example aspect, the method includes receiving, by a first radio access node, a multicast flow comprising data packets of a multicast service, determining, by the first radio access node, whether to initiate a handover procedure for a user device from the first radio access node to a second radio access node, replacing, upon determination to initiate the handover procedure, by the first radio access node, a first portion of the data packets with a flow identifier of a unicast flow, and forwarding, by the first radio access node, the data packets of the multicast service including the flow identifier of the unicast flow to the second radio access node.

Methods and systems for multicast data forwarding during mobility procedures in wireless communication networks

A wireless communication method for use in a first wireless network node is disclosed. The wireless communication method comprises receiving, from a first session management function, a temporary mobile group identity associated with a multicast/broadcast service and a wireless terminal, receiving, from a second session management function, a request for activating a multicast/broadcast service session corresponding to the temporary mobile group identity, and transmitting, to the first session management function, a message comprising information indicating a status of the multicast/broadcast service session in the first wireless network node.

Method for handling multicast/broadcast service session

A wireless communication method for use in a network node is disclosed. The method comprises receiving, from a communication node, a message indicating a capability of being a grand master clock, and transmitting, to the communication node, announce information associated with a first announce message based on the capability.

Methods, systems and apparatuses for 5G time synchronization

A method of handing over a mobile communication device from a first access network to a second access network (in one implementation) is as follows. In response to a protocol data unit session update request, a first computing device (e.g., an AMF) receives an identifier of a protocol data unit session and network slice information regarding a network slice to be used by the mobile communication device to communicate on the second access network using the protocol data unit session. The first computing device uses the network slice information to select a network slice instance and to select a second computing device (e.g., another AMF) within the network slice instance. The first computing device transmits, to the second computing device, a relocation request that includes the network slice information and the identifier of the protocol data unit session.
