M2M resource preservation in mobile networks

摘要

The present invention relates to a solution for handling a plurality of machine to machine, M2M, devices in a wireless communication cell by providing a shared Internet Protocol, IP, address for the plurality of M2M devices and one of the M2M devices acts as a master device for attaching and receiving the shared IP address and other communication configuration control data from a wireless gateway. The M2M devices communicate with a central M2M server using datagrams with the shared IP address and device identity information together with data or control messages.

1. A method in a packet based wireless communication network for handling machine to machine (M2M) communication with an M2M application server via a communication network gateway, wherein a plurality of M2M terminal devices are located in communicative radio range to the communication network gateway, the method comprising the steps of:
allocating one M2M terminal device as a master device; allocating the other M2M terminal devices as fellow terminal devices, which together with the master terminal device form an M2M system sharing one IP address; providing, in a packet datagram, source IP address and destination IP address, wherein one of the source IP address and destination IP address is the shared IP address; providing an M2M device identity of an M2M device for which a radio communication traffic transmission is intended in a payload field of the packet datagram such that M2M device addressing is transparent to the network; and listening, in the fellow terminal devices, to all radio communication traffic transmission related to the shared IP address of the M2M system and extracting the M2M device identity that indicates the M2M device for which the transmission is intended from packet datagrams related to the shared IP address, wherein the M2M device identity uniquely identifies a single one of the fellow terminal devices, wherein the M2M terminal devices are not being human operated.
