Method of distributing group message of machine type communication
First Claim
1. A method, in an interworking function device, of distributing a group message of machine type communication, the method comprising:
- receiving the group message from a service capability server, wherein the group message includes location/area information, radio access technology information, external group identifier information and/or application layer data;
selecting a transmission mode under a predetermined policy according to the group message or obtaining the transmission mode by querying a home location register or a home subscriber server according to the group message;
translating the location/area information into a geographical area in which the group message is transmitted and updating the group message with the geographical area;
mapping the external group identifier information to internal group identifier information according to information in the home location register or the home subscriber server and updating the group message with the internal group identifier information to obtain an updated group message;
querying the home location register or the home subscriber server according to the updated group message about a core network node or a broadcast system node for transmitting the group message; and
transmitting the updated group message to the core network node or the broadcast system node in the selected transmission mode;
wherein the predetermined policy in the selecting includes;
if the group message includes pure service data, then the transmission mode is a push mode using a cell broadcast service mode or a multimedia broadcast multicast service mode, and the transmitting further comprises;
transmitting the pure service data in push mode to the broadcast system node or core network node with an indication that the transmission comprises pure service data; and
wherein transmission of the pure service data from the broadcast system node or the core network node is devoid of a dispersion parameter in order to prevent receiving devices from initiating multiple responses concurrently.

Abstract
The invention relates to a method, in an interworking function device, of distributing a group message of machine type communication, the method including the steps of: receiving the group message from a service capability server, wherein the group message includes location/area information, radio access technology information, external group identifier information and/or application layer data; selecting a transmission mode under a predetermined policy according to the group message or obtaining the transmission mode by querying a home location register or a home subscriber server according to the group message; translating the location/area information into a geographical area in which the group message is transmitted and updating the group message with the geographical area; mapping the external group identifier information to internal group identifier information according to information in the home location register or the home subscriber server and updating the group message with the internal group identifier information to obtain an updated group message; querying the home location register or the home subscriber server according to the updated group message about a core network node or a broadcast system node for transmitting the group message; and transmitting the updated group message to the core network node or the broadcast system node in the selected transmission mode.
