Tracking registration buffer in a cellular network
First Claim
1. A computer-implemented method comprising:
- at a user entity that is initially operating in a first of a plurality of tracking areas in a radio access network (RAN), subsequently determining that the user entity has moved into a first coverage area of a second tracking area in the RAN in which the user entity is not registered;
determining that the second tracking area that is not included in a tracking area list (TAI list) of the user entity; and
in response to determining that the second tracking area that is not included in the TAI list;
(a) the user entity refraining from sending a registration message to register in the second tracking area until the earlier of;
(i) a threshold period of time elapsing and (ii) the user entity moving into another coverage area in the second tracking area that is different from the first coverage area; and
(b) the user entity subsequently sending the registration message to register in the second tracking area in response to the earlier of (i) the user entity determining that the user entity has remained in the first coverage area of the second tracking 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 tracking area.

Abstract
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.

4. A computer-implemented method comprising:
-
at a user entity that is initially operating in a first of a plurality of tracking areas in a radio access network (RAN), subsequently determining that the user entity has moved into a first coverage area of a second tracking area of the RAN in which the user entity is not registered; determining that the second tracking area that is not included in a tracking area list (TAI list) of the user entity; and in response to determining that the second tracking area that is not included in the TAI list; (a) the user entity refraining from sending a registration message to register in the second tracking area, at least until the user entity moves into another coverage area in the second tracking area that is different from the first coverage area; and (b) the user entity subsequently determining that the user entity has moved into a second coverage area in the second tracking area and responsively sending the registration message to register in the second tracking area. - View Dependent Claims (10, 11)

12. A radio access network (RAN) system comprising:
-
a non-transitory computer-readable medium; and program instructions stored on the non-transitory computer-readable medium and executable by at least one processor to; select a zone-update process for each of one or more user entities, wherein the zone-update process for each user entity is selected from a plurality of possible zone-update processes that include at least a first and a second zone-update process, wherein the first zone-update process comprises a delayed zone-update process, wherein the delayed zone-update process, when implemented by a given one of the user entities, causes the given user entity to respond to movement into a first coverage area of a new tracking area of the RAN in which the user entity has not yet registered, by waiting until the user entity moves into a second coverage area in the new tracking area that is different from the first coverage area, before sending a registration message to register in the new tracking area; and indicate the respectively selected zone-update process to each user entity. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A computer-implemented method comprising:
-
at a user entity that is initially operating in a first of a plurality of paging zones in a radio access network (RAN), wherein each paging zone comprises a set of one or more coverage areas, subsequently determining that the user entity has moved into a first coverage area of a second paging zone in the RAN; determining that the user entity is not registered in the second paging zone; and in response to determining that the user entity is not registered in the second paging zone; (a) the user entity refraining from sending a registration message to register in the second paging 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 paging zone that is different from the first coverage area; and(b) the user entity subsequently sending the registration message to register in the second paging zone in response to the earlier of (i) the user entity determining that the user entity has remained in the first coverage area of the second paging zone 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 paging zone.
