Methods providing network service restoration context and related service instance sets and storage resource nodes
A method to operate a first service instance set associated with a first storage resource node.

9. The method of claim 7 , wherein the selected subscriber identification comprises a subscriber permanent identifier, and wherein the plurality of subscriber identifications comprises a plurality of subscriber permanent identifiers.
10. The method of claim 1 , wherein the identification corresponds to a selected data network name of a plurality of data network names, and wherein the subgroup of context data comprises context data for the selected data network name.
11. The method of claim 10 , wherein the subgroup of context data excludes context data from the first storage resource node for at least one data network name of the plurality of data network name other than the selected data network name.
12. The method of claim 1 , wherein transmitting the access context request comprises transmitting the access context request responsive to receiving a get context request from a service controller node, and wherein transmitting the move context communication comprises transmitting a get context response including the subgroup of context data to the service controller node.
13. The method of claim 12 , wherein the get context request is received from a service controller node through an access node, and wherein the get context response is transmitted to the service controller node through the access node.
14. The method of claim 1 , wherein transmitting the move context communication comprises transmitting a store context request including the subgroup of context data to the second service instance set.
15. The method of claim 14 , wherein the store context request is transmitted to the second service instance set through an access node.
16. The method of claim 1 , wherein the access context request is transmitted responsive to at least one of receiving a transfer context request from a service controller node, through an access node, at least one of an internal trigger and event, and an instruction from an operation and maintenance node.
17. The method of claim 1 , wherein the first service instance set comprises a first plurality of instances of the service, and wherein the second service instance set comprises a second plurality of instances of the service.
18. A method of operating a service instance set associated with a storage resource node, the service instance set being for a service, and the storage resource node storing context data for the service, the method comprising:
transmitting a modify context request to the storage resource node, the modify context request including an identification for a subgroup of context data of the storage resource node to be modified, the subgroup of context data including a subgroup of network service restoration context (NSRC) data, the subgroup of NSRC data including context data used to recover an expected network state in an event of failure, the network service restoration context data stored in the storage resource node with vendor specific context data, the subgroup of context data excluding the vendor specific context data and the vendor specific context data including at least one of vendor specific implementation context data and vendor specific proprietary context data.
19. The method of claim 18 , wherein the modify context request is a create context request, and wherein the create context request includes context data corresponding to the subgroup to be used by the storage resource node to create the subgroup of context data.
20. The method of claim 18 , wherein the modify context request is an update context request, and wherein the update context request includes context data corresponding to the subgroup to be used by the storage resource node to update the subgroup of context data.
21. The method of claim 18 , wherein the modify context request is a delete context request instructing the storage resource node to delete the subgroup of context data.
22. The method of claim 18 , wherein the identification corresponds to a selected protocol data unit session of a plurality of protocol data unit sessions, and wherein the subgroup of context data comprises context data for the selected protocol data unit.
23. The method of claim 22 , wherein the subgroup of context data excludes context data from the storage resource node for at least one protocol data unit session of the plurality other than the selected protocol data unit.
