Abstract
A radio terminal establishes a control connection with a network, and receives, from the network, a selection policy used for selection of a core network entity that provides a mobility management service or a data transmission service for the radio terminal. Further, the radio terminal selects a target core network entity based on the selection policy, and transmits, to the network, a request message for requesting provision of the mobility management service or the data transmission service by the target core network entity.
Claims8
-30. (canceled)
A network apparatus comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- receive from a radio terminal a change request for a core network entity, the change request explicitly indicating a target core network entity determined by the radio terminal;
- and
- in response to the change request, communicate with a serving core network entity that is currently providing a mobility management service or a data transmission service for the radio terminal, to transfer the mobility management service or the data transmission service from the serving core network entity to the target core network entity.
A method performed by a network apparatus, comprising:
- receiving from a radio terminal a change request for a core network entity, the change request explicitly indicating a target core network entity determined by the radio terminal;
- and
- in response to the change request, communicating with a serving core network entity that is currently providing a mobility management service or a data transmission service for the radio terminal, to transfer the mobility management service or the data transmission service from the serving core network entity to the target core network entity.
A non-transitory computer readable medium storing a program for causing a computer to perform a method in a network apparatus,
- wherein the method comprises:
- receiving from a radio terminal a change request for a core network entity, the change request explicitly indicating a target core network entity determined by the radio terminal;
- and
- in response to the change request, communicating with a serving core network entity that is currently providing a mobility management service or a data transmission service for the radio terminal, to transfer the mobility management service or the data transmission service from the serving core network entity to the target core network entity.
