Tracking registration buffer in a cellular network

摘要

Embodiments described herein may help to provide a delayed zone-update process. An exemplary method may involve a user entity, which is initially operating in a first of a plurality of multi-coverage-area zones in a radio access network (RAN), subsequently determining that the user entity has moved into a second multi-coverage-area zone of the RAN, wherein the user entity is located in a first coverage area of the second multi-coverage-area zone. In response, the user entity may refrain from sending a registration message to register in the second multi-coverage-area zone until the earlier of: (i) a threshold period of time elapsing and (ii) the user entity moving into another coverage area in the second multi-coverage-area zone that is different from the first coverage area.

1. A computer-implemented method comprising:
at a user entity that is initially operating in a first of a plurality of multi-coverage-area zones in a radio access network (RAN), subsequently determining that the user entity has moved into a second multi-coverage-area zone of the RAN, wherein the user entity is initially located in a first coverage area of the second multi-coverage-area zone when the user entity moves into the second multi-coverage-area zone; and in response to determining that the user entity has moved into the second multi-coverage-area zone:
(a) the user entity refraining from sending a registration message to register in the second multi-coverage-area zone until the earlier of: (i) the user entity remaining in the first coverage area for at least a threshold period of time and (ii) the user entity moving into another coverage area in the second multi-coverage-area zone that is different from the first coverage area; and(b) the user entity subsequently sending the registration message to register in the second multi-coverage-area zone in response to the earlier of (i) the user entity determining that the user entity has remained in the first coverage area for the threshold period of time and (ii) the user entity determining that the user entity has moved into a second coverage area in the second multi-coverage-area zone.
