Problems solved by technology

[0004] In the M2M application, if the operator needs to multicast the M2M application terminal through Multimedia Broadcast Multicast Service (MBMS for short) or Cell Broadcast Center (CBC for short) To send data packets, due to the large number of M2M application terminals, according to the H2H processing mechanism, the GGSN needs to configure the relationship between the M2M application terminal identifier and the M2M application terminal IP address for each M2M application terminal, which will consume a lot of IP address resources

Embodiment 1

[0042] like image 3 Shown is a flow chart of Embodiment 1 of a method for delivering a data packet by an M2M application server of the present invention, including:

[0043] Step 101: The M2M application server obtains the group identifier of the target group. The destination group is the group of the data packet to be received.

[0044] Step 102: The M2M application server obtains the IPv6 address prefix corresponding to the group identifier of the target group according to the correspondence between the IPv6 address prefix and the group identifier. The M2M application server itself may configure the correspondence between IPv6 address prefixes and group identifiers, or the M2M application server may obtain the correspondence between the two from network-side entities such as HSS, HLR, and group subscription database.

[0045] Step 103: The M2M application server sends the data packet to the GGSN serving the destination group according to the IPv6 address prefix. Specific...

Embodiment 2

[0057] The second embodiment may further include: the M2M application server obtains the identification information of a certain M2M application terminal in the target group; the data packet sent by the M2M application server to the GGSN serving the target group also carries a certain M2M application terminal. identification information. After step 203, it may further include: the GGSN obtains the IPv4 address in the data packet and the identification information of the M2M application terminal, obtains the group identification of the target group according to the correspondence between the IPv4 address and the group identification, and sends the data packet to the target group. The M2M application terminal corresponding to the identification information of the M2M application terminal in the group.

[0058] In the second embodiment, by enhancing or expanding the protocol stack function between the M2M application server and the GGSN, the data packets sent by the M2M applicati...

Abstract

The present invention discloses a method and system for transmitting data packets at a Machine-to-Machine (M2M) application server, wherein the method comprises: the M2M application server obtains a group identifier of a destination group; according to the correspondence between IPv6 address prefixes and group identifiers, the M2M application server obtains the IPv6 address prefix corresponding to the group identifier of the destination group; according to the IPv6 address prefix, the M2M application server transmits the data packets to the Gateway GPRS Support Node (GGSN) serving the destination group, wherein the IPv6 address prefix is carried in the data packets. In an embodiment of the present invention, an IPv6 address prefix is allocated for a group in M2M application, a group identifier of a destination group is obtained according to the IPv6 address prefix, and the data packets are transmitted to the GGSN serving the destination group, thereby transmitting the data packets to M2M application terminals in a group can be implemented, and the resource of IP address can be saved.

Description

technical field [0001] The invention relates to communication technology, in particular to a method and a system for delivering data packets by an M2M application server, and also to an M2M application server and a GGSN. Background technique [0002] Machine to Machine (M2M) application refers to the network communication between one or more network elements without human participation, such as traffic control and management, factory monitoring, remote meter reading and other applications . In the M2M application, multiple M2M application terminals with the same M2M application (the English corresponding to the M2M application terminal may be M2M Equipment, M2M Device, or Machine Type Communication Device, etc.) form a whole, which is referred to as a group. Network operators or industry users can manage and control the group as a whole. For example, a remote meter reading application in the electric power industry can form a group of all electric meters in a city, and net...
