7 is an example of a sequence in which a plurality of M2M devices transmit data in a predetermined time domain. 7 is an example of a criterion for determining the order in which M2M devices belonging to the same M2M group transmit data packets to the mobile communication network. 7 assumes that the subject determining the data packet delivery order of the M2M device knows location information of the M2M device in advance.
FIG. 7A shows an example in which the order is determined according to whether or not the M2M device is located in a specific area. In Fig. 7 (a), the M2M device shows a temperature sensor as an example. In Fig. 7 (a), the dotted circle means a specific region (or position). There may be a priority in which a data packet is delivered according to a specific location in advance. In FIG. 7 (a), the number displayed in each area corresponds to a priority for transmitting a data packet. 7A shows an example in which there is no M2M device in the area corresponding to the second priority.
7B is an example of determining the data packet delivery order based on the distance between the M2M device and the AP serving as an AP. In Fig. 7 (b), the M2M device shows CCTV as an example. FIG. 7 (b) shows an example in which the order of data packet delivery is determined according to the order of closest distance between the base station and the M2M device.
Furthermore, various criteria not shown in FIG. 7 may be used. Of course, without special criteria, an administrator or service provider could manually configure a particular M2M device to determine the data packet in a particular order.

When an M2M device sends a packet at random, it can send a data packet at the same time. That is, data packets may collide. A way to avoid this would be needed. 9 is another example of a time domain in which a plurality of M2M devices sharing one terminal identifier transmits data. 9 shows an inactive period in a time domain in which M2M devices transmit data. The inactivity period corresponds to a time domain in which a configuration of the mobile communication network or the
