[0005] However, the existing group communication methods applied to M2M only save the communication between the M2M application server and the group server, and the group server still needs to send a request to each M2M device separately
If the capacity of the group server is limited (such as an M2M gateway), or the network bandwidth between it and the M2M device is small or the communication cost is high, the communication between the group server and the M2M device in this method is not economical

Embodiment Construction
[0074] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0075] Such as figure 1 As shown, the method for accessing group resources provided by the embodiment of the present invention includes the following steps:
[0076] Step 101. Receive an access request to a member resource, where the access request to a member resource carries a group resource identifier of the group resource to which the member resource belongs;
[0077] Specifically, the first group server receives an access request to member resources. For exa...

The present invention provides a method for accessing member resources. The group server and member devices can send information to the member devices where the member resources in the group resources are located through the established mapping relationship between the multicast address and the fan-out URI in the group resources. Send a member resource access request in a multicast manner, and include the fan-out URI in the member resource access request; so that the member device to which the member resource belongs is on the member device according to the member resource indicated by the fan-out URI The access path performs the operation indicated by the member access request. Therefore, the group server does not need to unicast the access request to each member device, which saves network overhead.
Description
technical field [0001] The present invention relates to the technical field of Machine-to-Machine Communications (M2M), in particular to a method for accessing member resources, a group server and member devices. Background technique [0002] Machine-to-Machine Communications (M2M) is a networked application and service centered on machine intelligence interaction. M2M technology realizes data communication without human intervention by embedding wireless or wired communication modules and application processing logic inside the machine, so as to meet users' informatization needs for monitoring, command and dispatch, data collection and measurement. In the M2M system architecture, various M2M terminals (such as sensors, microcontrollers, etc.) are directly or remotely connected to the M2M service platform through the M2M gateway, while various M2M application servers (such as power meter reading, intelligent transportation, etc.) The service capability provided by the M2M s...
