Abstract

Embodiments of the present invention disclose a method for switching of a device, an M2M platform and a network system. The method includes: a machine-to-machine M2M platform receives a re-registration message including a position of a device in a network service capability layer NSCL resource tree before registration and a position of the device in the resource tree of the NSCL after registration; the M2M platform generates mapping relationship between the position of the device in the resource tree of the NSCL before registration and the position of the device in the resource tree of the NSCL after registration. By way of the present invention, the problem in the prior art can be solved in a manner of re-registration.

First claim

What is claimed is:

1. A method for switching of a device, comprising:
receiving, by a machine-to-machine (M2M) platform, a re-registration message, wherein the re-registration message comprises a position of the device in a resource tree of a network service capability layer (NSCL) before registration and a position of the device in the resource tree of the NSCL after registration; and
generating, by the M2M platform, a mapping relationship between the position of the device in the resource tree of the NSCL before registration and the position of the device in the resource tree of the NSCL after registration.

2. The method according to claim 1 , wherein the re-registration message further comprises a network address of the device after registration, the method further comprising:
updating, by the M2M platform, according to the network address of the device after registration in the re-registration message, a network address of the device in a domain name system (DNS) server, so that a network application server makes a request to the DNS server to receive the network address of the device after registration; and
accessing, by the network application server, the device according to the received network address of the device after registration.

3. The method according to claim 1 , wherein, before receiving, by the M2M platform, the re-registration message, the method further comprises:
receiving, by a gateway service capability layer (GSCL), a device triggering message sent by the device, wherein the device triggering message comprises an identity of the device and an identity of an NSCL to which the device belongs before registration; and
constructing, by the GSCL, the re-registration message according to the device triggering message, and sending the re-registration message to the M2M platform.

4. The method according to claim 1 , wherein the method further comprises:
determining, by the M2M platform, according to the position of the device in the resource tree of the NSCL after registration, that the device does not have service capability layer (SCL) capability after registration, and determining, according to the position of the device in the resource tree of the NSCL before registration, that the device has the SCL capability before registration, notifying the device of setting an SCL capability state of the device to be OFF, and deleting a resource related to the device; or
determining, by the M2M platform, according to the position of the device in the resource tree of the NSCL after registration, that the device has the SCL capability after registration, and determining, according to the position of the device in the resource tree of the NSCL before registration, that the device does not have the SCL capability before registration, notifying the device of setting the SCL capability state of the device to be ON, and adding the resource related to the device in the resource tree of the NSCL.

5. The method according to claim 1 , wherein the method further comprises:
determining, by the M2M platform, according to the position of the device in the resource tree of the NSCL after registration, a target gateway where the device is located after registration, and determining, according to the position of the device in the resource tree of the NSCL before registration, a source gateway where the device is located before registration, notifying a source gateway service capability layer (SCL) of the device of performing de-registration, so that the source gateway SCL can delete a resource related to the device; and
notifying, by the M2M platform, a target gateway SCL of the device of creating the resource related to the device according to service data of the device.

6. The method according to claim 1 , wherein the method further comprises:
receiving, by the M2M platform, a resource accessing request sent by a network application server, wherein the resource accessing request comprises information on the position of the device in the resource tree of the NSCL before registration; and
inquiring, by the M2M platform, the mapping relationship to obtain the position of the device in the resource tree of the NSCL after registration corresponding to the position of the device in the resource tree of the NSCL before registration, and sending a redirection message to the network application server, so that the network application server accesses the M2M platform according to information on the position of the device in the resource tree of the NSCL after registration.

7. The method according to claim 1 , wherein the device triggering message further comprises a network address of the device after registration.

8. A method for switching of a device, comprising:
receiving, by a gateway service capability layer (GSCL) module, a device triggering message sent by a device in a machine-to-machine (M2M) system, wherein the device triggering message comprises an identity of the device and an identity of a network service capability layer (NSCL) to which the device belongs before registration; and
constructing, by the GSCL module, a re-registration message according to the device triggering message, and sending the re-registration message to an M2M platform, wherein the re-registration message comprises a position of the device in a resource tree of the NSCL before registration and a position of the device in the resource tree of the NSCL after registration, so that the M2M platform generates a mapping relationship between the position of the device in the resource tree of the NSCL before registration and the position of the device in the resource tree of the NSCL after registration.

9. The method according to claim 8 , wherein the device triggering message further comprises a network address of the device after registration, and the re-registration message further comprises the network address of the device after registration, so that the M2M platform updates the network address of the device in a domain name system (DNS) server according to the network address of the device after registration in the re-registration message.

10. The method according to claim 8 , further comprising:
when the M2M platform determines, according to the position of the device in the resource tree of the NSCL after registration, that the device does not have service capability layer (SCL) capability after registration, and determines, according to the position of the device in the resource tree of the NSCL before registration, that the device has the SCL capability before registration, receiving, by the NSCL module, an OFF notification sent by the M2M platform, setting a device SCL capability state of the device to be OFF according to the OFF notification, and deleting a resource related to the device; or
when the M2M platform determines, according to the position of the device in the resource tree of the NSCL after registration, that the device has the SCL capability after registration, and determines, according to the position of the device in the resource tree of the NSCL before registration, that the device does not have the SCL capability before registration, receiving, by the device, an ON notification sent by the M2M platform, and setting the device SCL capability state of the device to be ON according to the ON notification.

11. The method according to claim 8 , further comprising:
when the M2M platform determines, according to the position of the device in the resource tree of the NSCL after registration, a target gateway where the device is located after registration, and determines, according to the position of the device in the resource tree of the NSCL before registration, a source gateway where the device is located
