Claim 5:
6. A method comprising:
initiating, with a terminal device, a request for registration to a network, wherein initiating a request for registration to the network comprises:
detecting a change of a serving beam for the terminal device;
in response to a detection that the serving beam for the terminal device changes from a first beam to a second beam, detecting an identity of the second beam;
determining whether the identity of the second beam is included in a previous response to a previous request for registration; and
in response to a determination that the identity of the second beam is missed in the previous response, initiating the request for registration to the network;
receiving a response to the request, the response comprising an identity of each of beams and associated timings indicating when the beams cover a location of the terminal device, the beams able to cover the location of the terminal device during at least one time period indicated with the associated timings, the beams being from one or more satellites; and
updating a local context associated with the registration to the network with the response.
