Abstract
This application provides a communications method and a communications apparatus, to reduce storage resources required by an access network device to store a context of a terminal device. The method includes: The access network device gathers terminal devices that have a same attribute in a group, where a context of each terminal device is divided into two parts: a common context and a dedicated context, the common context is shared by all the terminal devices in the group, and the dedicated context is a context specific to the terminal device. The access network device stores one common context for each group and stores a dedicated context of each terminal device in the group, to maintain the context of each terminal device.
Claims19
A communications method applied in a terminal device, comprising:
- receiving a first message from a first access network device, wherein the first message comprises a group identifier corresponding to a terminal device and an identifier of the terminal device, wherein the group identifier is used to identify a group to which the terminal device belongs, wherein the identifier of the terminal device is used to identify the terminal device in the group to which the terminal device belongs, wherein the group identifier corresponds to a common context shared by all terminal devices in the group to which the terminal device belongs, and wherein the identifier of the terminal device corresponds to a dedicated context of the terminal device;
- and
- storing the group identifier and the identifier of the terminal device, wherein the group includes a plurality of candidate terminal devices that include the terminal device, and wherein a context of each of the candidate terminal devices includes the common context and a dedicated context specific to the candidate terminal device.
A communications method, comprising:
- determining a group identifier corresponding to a terminal device and an identifier of the terminal device, wherein the group identifier is used to identify a group to which the terminal device belongs, wherein the identifier of the terminal device is used to identify the terminal device in the group to which the terminal device belongs, wherein the group identifier corresponds to a common context shared by all terminal devices in the group to which the terminal device belongs, and wherein the identifier of the terminal device corresponds to a dedicated context of the terminal device;
- and
- sending a first message to the terminal device, wherein the first message comprises the group identifier and the identifier of the terminal device, wherein the group includes a plurality of candidate terminal devices that include the terminal device, and wherein a context of each of the candidate terminal devices includes the common context and a dedicated context specific to the candidate terminal device.
A communications method, comprising:
- receiving, by a second access network device, a second message from a terminal device, wherein a group includes a plurality of candidate terminal devices that include the terminal device, and wherein a context of each of the candidate terminal devices includes a common context and a dedicated context specific to the candidate terminal device, wherein the second message is usable for the terminal device to request to access the second access network device;
- determining, by the second access network device based on the second message, a group identifier corresponding to the terminal device and an identifier of the terminal device, wherein the group identifier is used to identify the group to which the terminal device belongs, wherein the identifier of the terminal device is used to identify the terminal device in the group to which the terminal device belongs, and wherein the identifier of the terminal device corresponds to the dedicated context of the terminal device;
- sending, by the second access network device, a third message to a first access network device, wherein the third message comprises the group identifier and the identifier of the terminal device;
- and
- receiving, by the second access network device, a third response message from the first access network device, wherein the third response message comprises the dedicated context.
