Abstract
Methods and apparatuses for improving service continuity are disclosed. The solution comprises storing (300) information slice remapping describing how a given net-work slice may be mapped to another network slice, receiving (302) a first message from an access node, that the node serves a terminal or has received a request to serve a terminal utilising a network slice not supported by the node and transmitting (304) based on the first message a message to a network entity responsible for session management to control the connection of the terminal, with the information on slice remapping and/or activity status of the packet data unit sessions associated with the slice not supported by the node.

1-40. (canceled)
An apparatus in a communication network, comprising:
- at least one processor;
- and at least one memory including computer program code,
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform:
- store information on slice remapping describing how a given network slice may be mapped to another network slice;
- receive a first message from an access node, that the node serves a terminal or has received a request to serve a terminal utilising a network slice not supported by the node;
- transmit based on the first message a message to a network entity responsible for session management to control the connection of the terminal, with the information on slice remapping or activity status of the packet data unit sessions associated with the slice not supported by the node.
A method in an apparatus in a communication network, comprising:
- storing information on slice remapping describing how a given network slice may be mapped to another network slice;
- receiving a first message from an access node, that the node serves a terminal or has received a request to serve a terminal utilising a network slice not supported by the node;
- transmitting based on the first message a message to a network entity responsible for session management to control the connection of the terminal, with the information on slice remapping or activity status of the packet data unit sessions associated with the slice not supported by the node.
A computer program comprising instructions for causing an apparatus to perform at least the following:
- storing information on slice remapping describing how a given network slice may be mapped to another network slice;
- receiving a first message from an access node, that the node serves a terminal or has received a request to serve a terminal utilising a network slice not supported by the node;
- transmitting based on the first message a message to a network entity responsible for session management to control the connection of the terminal, with the information on slice remapping or activity status of the packet data unit sessions associated with the slice not supported by the node.
