Embodiment 1

[0042] An embodiment of the present invention provides a method for updating group member information, which is applied on the group host side, such as figure 1 As shown, it specifically includes the following steps:

[0043] Step S101, after the group host creates a group resource, send a group creation notification carrying group information to the host of each group member, so that the host of each group member can store the group information;

[0044] Step S102, when the group member is deleted on the corresponding host side, the group host receives the update group resource request message sent by the host who deleted the group member, and according to the request message, deletes the group member who has been deleted on the host side Remove from group.

[0045] The method described in this embodiment notifies the host of each member of the group information when the group resource is created. When a member host deletes a member on the host side, the group host to which th...

Embodiment 2

[0050] An embodiment of the present invention provides a method for updating group member information, which is applied on the member host side, such as figure 2 As shown, it specifically includes the following steps:

[0051] Step S201, the host of the group member receives the group creation notification sent by the group host, extracts the group information from the creation notification and stores it;

[0052] Step S202, after deleting a certain group member, the host of the group member sends an update group resource request message to the group hosts of all groups including the deleted group member according to the stored group information, so that The corresponding group host deletes the group members who have been deleted at the member host side from the group.

[0053] It can be seen that when a member is deleted on the member host side, the member host will send a deletion notification to all groups containing the member to achieve the purpose of information synchr...

application example 1

[0059] This application example provides a group creation method, such as image 3 shown, including the following steps:

[0060] In step S301, the initiator AE or CSE sends a request for creating a group resource, the destination address is set as the URI of the group host CSE, and carries member list information.

[0061] In step S302, the group host creates group resources for the initiator.

[0062] Step S303, the group host sends a request to the host of each member to add group information to the group information according to the member list information, and the request carries the group information, such as the URI of the group resource.

[0063] Step S304, after receiving the request, the member host extracts the group information and stores it in the group information list in the group attribute.

[0064] Specifically, after extracting the information of the group, the member host judges whether the group attribute has been established locally. If it has been creat...

Abstract

The invention discloses a group member information updating method and device. The method includes: after a group host creates a group resource, the group host transmits a group creating notification to the host of each group member to allow the host of each group member store the group information; when a group member is deleted on the corresponding host side, the group host receives the group resource updating request message transmitted by the host deleting the group member, and the group host deletes the group member deleted on the host side from the group according to the request message. By the method, invalid operations on group resources by deleted members are avoided, and network resources are saved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for updating group member information. Background technique [0002] Machine-to-machine communication refers to data communication between machines without human participation. It is applicable to scenarios such as traffic control management, remote meter reading, remote monitoring, medical monitoring, and smart home control. In order to provide a standardized interface between the machine and the equipment of the machine communication system, the OneM2M standard organization defines the standard specification of the machine communication system. [0003] In this standard specification, group communication scenarios are supported. Assume that resource a, resource b, and resource c already exist in the system. Business entity) to create a group resource, the resource includes group member list information, and the group member list information includes ...
