Methods for establishing and using public path, M2M communication method, and systems thereof

摘要

Embodiments of the present invention, relating to the communications field, provide methods for establishing and using a public path, an M2M communication method, and systems thereof. To reduce occupied network resources and improve service processing efficiency of a network, an embodiment of the present invention provides the following technical solution: obtaining characteristic information of a public path, where the public path is corresponding to an MTC device in a one-line transmission group; establishing the public path according to the characteristic information; performing, by the MTC device in the one-line transmission group, data transmission with an MTC server by using the public path; and releasing the public path when the data transmission between the MTC device in the one-line transmission group and the MTC server is completed. The present invention is applicable to M2M communication.

主权项

1. A method of establishing a public path in a wireless communication network, comprising:
sending, by a mobility management entity (MME), a Create Session Request message to a serving gateway; receiving, by the MME, a Create Session Response message sent by the serving gateway, wherein the Create Session Response message is a response to the Create Session Request message and carries a network address of the serving gateway and tunnel endpoint ID information; sending, by the MME, a Create Bearer Request message to a base station, wherein the Create Bearer Request message carries the network address of the serving gateway and the tunnel endpoint ID information; and receiving, by the MME, a Create Bearer Request Response sent by the base station to complete establishment of the public path.
