Abstract
There is provided an apparatus, said apparatus comprising means for providing a first registration request from a user equipment to a first visited network for a first network slice provided by the first visited network and providing a further registration request from the user equipment to at least one second visited network for at least one second network slice provided by the second visited network, wherein the first network slice and at least one second network slice are mapped to subscribed network slices in a home network and the at least one second network slice is not provided by the first visited network.
Claims10
A user equipment comprising:
- at least one processor and
- at least one memory storing instructions which, when executed by the at least one processor, cause at least performance of:
- providing a first registration request from the user equipment to a first visited network for a first network slice provided by the first visited network;
- and
- providing a further registration request from the user equipment to at least one second visited network for at least one second network slice provided by the at least one second visited network,
- wherein the first network slice and at least one second network slice are mapped to subscribed network slices in a home network and the at least one second network slice is not provided by the first visited network which provided the first network slice.
An apparatus comprising:
- at least one processor and
- at least one memory storing instructions which, when executed by the at least one processor, cause at least performance of:
- receiving registration information for a user equipment from a first visited network and at least one second visited network;
- providing a subscription request from a home network associated with the user equipment to each of the first visited network and the at least one second visited network;
- receiving an indication at the home network from each of the first visited network and the at least one second visited network when the user equipment moves from a first state to a second state and from the second state to the first state;
- and
- storing a current state of the user equipment for each of the first visited network and the at least one second visited network,
- wherein the first visited network provides a first network slice and the at least one second visited network provides at least one second network slice,
- wherein the first network slice and the at least one second network slice are mapped to subscribed network slices in the home network, and the at least one second network slice is not provided by the first visited network;
- and
- storing, in the home network, the registration information for each of the first visited network and the at least one second visited network.
