Abstract
A method and apparatus of content transmission based on multimedia broadcast/multicast service (MBMS) in a machine type communication (MTC). A BM-SC receives a session start time from a MTC server; sends to a plurality of MTC devices a service announcement including the session start time; begins to establish MBMS bearers to the plurality of MTC devices when the session start time is reached; and transmits MTC service content from the MTC server to the plurality of MTC devices via the MBMS bearers. A MTC device receives a service announcement including a session start time therein; when the session start time is reached, wakes up to receive a notification about the MBMS bearers; and then receives MTC service contents transmitted via the MBMS bearers.

A method of content transmission based on multimedia broadcast/multicast service (MBMS) in a machine type communication (MTC), comprising:
- receiving a session start time from a MTC server;
- sending to a plurality of MTC devices a service announcement including the session start time;
- beginning to establish MBMS bearers to the plurality of MTC devices when the session start time is reached;
- and
- transmitting to the plurality of MTC devices via the MBMS bearers, MTC service contents coming from the MTC server;
- wherein the service announcement is sent to the plurality of MTC devices via the MBMS bearers at a fixed time point preconfigured to the plurality of MTC devices;
- and
- at the fixed time point, waking up the plurality of MTC devices to receive the service announcement via the MBMS bearers.
A method for receiving contents based on multimedia broadcast/multicast service (MBMS) in a machine type communication (MTC), comprising:
- receiving from a MBMS service apparatus a service announcement including a session start time;

- wherein the service announcement is sent to the plurality of MTC devices via the MBMS bearers at a fixed time point preconfigured to the plurality of MTC devices;
- and
- at the fixed time point, waking up the plurality of MTC devices to receive the service announcement via the MBMS bearers.
A content receiving apparatus based on multimedia broadcast/multicast service (MBMS) in a machine type communication (MTC), comprising:
- a processor configured to:
- receive from a MBMS service apparatus a service announcement including a session start time therein;
- receive a notification about MBMS bearers established for the session start time by the MBMS service apparatus;
- and
- receive MTC service contents transmitted via the MBMS bearers;
- instruct the MBMS bearer receiving means to wake up when the session start time is reached, so as to receive the announcement and the MTC service contents;
- pre-configure a fixed time point for receiving the service announcement;
- and
- at the fixed time point, wake up and receiving the service announcement via the MBMS bearers.
