Abstract

The present invention discloses a communication method for machine-type-communication (MTC) between a MTC server and MTC equipments, which comprises: the MTC server broadcasts a target content related to an application, receives availability information related to the target content from candidate MTC equipments which satisfy the target content, selects any one or more MTC equipments from the candidate MTC equipments based on the availability information, establishes a session connection with each of the selected MTC equipments, and receives content uploaded by the selected MTC equipments. The invention furthermore discloses a communication method for MTC between the MTC equipments and the MTC server, and discloses the corresponding MTC server and the MTC equipment.

Claims

1. A communication method for machine-type communication (MTC) between an MTC server and MTC equipments, comprising:

broadcasting a target content related to an application by the MTC server;

receiving availability information related to the target content from candidate MTC equipments which satisfy the target content;

selecting any one or more MTC equipments from the candidate MTC equipments based on the availability information;

establishing a session connection with each of the selected MTC equipments; and

receiving contents uploaded by the selected MTC equipments.

2. The method according to claim 1, further comprising:

determining whether it is needed to establish a new session connection;

releasing the current session connection if it is needed to establish a new session connection; and

executing the broadcasting step to the session connection establishment step.

3. The method according to claim 2, wherein the step of determining whether it is needed to establish a new session connection comprises:

checking whether the content uploaded by each of the selected MTC equipments satisfies the target content; and

determining that it is needed to establish a new session connection, if the content uploaded by any one of the selected MTC equipments does not satisfy the target content.

4. The method according to claim 2, wherein the step of determining whether it is needed to establish a new session connection comprises:

monitoring whether information is received from any one of the selected MTC equipments indicating that the MTC equipment is unavailable; and

determining that it is needed to establish a new session connection if the information is received.

5. The method according to claim 2, wherein the step of determining whether it is needed to establish a new session connection comprises:

checking whether the content uploaded by each of the selected MTC equipments satisfies the target content;

determining that it is needed to establish a new session connection, if the content uploaded by any one of the selected MTC equipments does not satisfy the target content;

monitoring whether information is received from any one of the selected MTC equipments indicating that the MTC equipment is unavailable; and

determining that it is needed to establish a new session connection, if the information is received.

6. The method according to claim 1, wherein the step of selecting any one or more MTC equipments from the candidate MTC equipments based on the availability information comprises:

comparing the availability information of the candidate MTC equipments with each other; and

selecting the best MTC equipment according to a requirement of the application.

7. A communication method for machine-type communication (MTC) between an MTC equipment and an MTC server, comprising:

receiving, by the MTC equipment, a target content related to an application broadcasted by the MTC server;

determining whether the MTC equipment satisfies the target content;

sending availability information related to the target content to the MTC server if the MTC equipment satisfies the target content; and

establishing a session connection with the MTC server in response to a session connection request from the MTC server; and

uploading content onto the MTC server.

8. The method according to claim 7, further comprising:

determining whether the MTC equipment satisfies the target content during the uploading of the content onto the MTC server; and

notifying the MTC server of information indicating that the MTC equipment is unavailable, if the MTC equipment does not satisfy the target content.

9. An machine-type communication (MTC) server for MTC, comprising:

broadcasting module configured to broadcast a target content related to an application;

reception module configured to receive availability information related to the target content from candidate MTC equipments which satisfy the target content;

selection module configured to select any one or more MTC equipments from the candidate MTC equipments based on the availability information; and

connection establishment module configured to establish a session connection with each of the selected MTC equipments;

wherein the reception module is further configured to receive content uploaded by the selected MTC equipments upon the establishment of the session connection.

10. The MTC server according to claim 9, further comprising:

determination module configured to determine whether it is needed to establish a new session connection; and

connection release module configured to release the current session connection if it is needed to establish a new session connection.

11. The MTC server according to claim 10, wherein the determination module comprises:

check unit configured to check whether the content uploaded by each of the selected MTC equipments satisfies the target content; and

determination unit configured to, if the check unit checks that the content uploaded by any one of the selected MTC equipments does not satisfy the target content, determine that it is needed to establish a new session connection.

12. The MTC server according to claim 10, wherein the determination module comprises:

monitoring unit configured to monitor whether information is received from any one of the selected MTC equipments indicating that the MTC equipment is unavailable; and

determination unit configured to, if the monitoring unit receives the information, determine that it is needed to establish a new session connection.

13. The MTC server according to claim 10, wherein the determination module comprises:

check unit configured to check whether the content uploaded by each of the selected MTC equipments satisfies the target content;

monitoring unit configured to monitor whether information is received from any one of the selected MTC equipments indicating that the MTC equipment is unavailable; and

determination unit configured to, if the check unit checks that the content uploaded by any one of the selected MTC equipments does not satisfy the target content or the monitoring unit receives the information, determine that it is needed to establish a new session connection.

14. The MTC server according to claim 9, wherein the selection module comprises:

comparison unit configured to compare the availability information of the candidate MTC equipments with each other; and

selection unit configured to select the best MTC equipment according to requirements of the application.

17. A communication system for machine-type communication (MTC), comprising:

the MTC server according to claim 9; and

at least one MTC equipment comprising reception module configured to receive a target content related to an application broadcasted by the MTC server, determination module configured to determine whether the MTC equipment satisfies the target content, sending module configured to send availability information related to the target content to the MTC server if the MTC equipment satisfies the target content and connection establishment module configured to establish a session connection with the MTC server in response to a session connection request from the MTC server, wherein the sending module is further configured to upload content onto the MTC server upon the establishment of the session connection.
