Abstract
This application provides an information transmission method when a terminal device accesses a serving radio access network (RAN) device. The terminal device receives an identifier of a first cluster-data function (C-DF) associated with the serving RAN device from the serving RAN device, where the first C-DF is located in a radio access network and stores current data of the terminal device. When the terminal device camps on the serving RAN device longer than or equal to a first threshold, the terminal device stores the identifier of the first C-DF.
Claims11
A terminal device, comprising at least one processor, a transceiver coupled with the at least one processor, and a non-transitory computer-readable storage medium coupled with the at least one processor and configured to store a program including instructions that, when being executed by the at least one processor, cause the at least one processor to:
- access a serving radio access network (RAN) device;
- receive an identifier of a first cluster-data function (C-DF) from the serving RAN device through unicast signaling or in a broadcast message sent by the serving RAN device, wherein the serving RAN device is associated with the first C-DF, and the first C-DF is located in a radio access network and stores current data of the terminal device;
- and
- store the identifier of the first C-DF when a duration in which the terminal device camps on the serving RAN device is greater than or equal to a first threshold.
A radio access network (RAN) device, comprising at least one processor, a transceiver coupled with the at least one processor, and a non-transitory computer-readable storage medium coupled with the at least one processor and configured to store a program including instructions that, when being executed by the at least one processor, cause the at least one processor to:
- obtain an identifier of a first cluster-data function (C-DF) associated with the RAN device, wherein the first C-DF is located in a radio access network and stores current data of a terminal device;
- and
- send the identifier of the first C-DF to the terminal device through unicast signaling or via a broadcast message broadcast in a service area.
A cluster-data function (C-DF), comprising at least one processor, a transceiver coupled with the at least one processor, and a non-transitory computer-readable storage medium coupled with the at least one processor and configured to store a program including instructions that, when being executed by the at least one processor, cause the at least one processor to:
- receive an identifier of a terminal device and an identifier of a second C-DF from at least one RAN device associated with the C-DF, through unicast signaling or via a broadcast message sent by the at least one RAN device, wherein the C-DF is located in a radio access network and stores current data of the terminal device, and an identifier of the C-DF is different from the identifier of the second C-DF;
- and
- obtain data of the terminal device from the second C-DF.
