Method and device for deregistering terminal peripheral
View Patent ↗A method and device for deregistering a terminal peripheral are provided. The method comprises: a gateway sends the request message for deregistering the terminal peripheral to the terminal peripheral; and the gateway deletes registration information of the terminal peripheral stored by the gateway. By means of the disclosure, the technical problem of the storage resource waste in the related art is solved where the gateway cannot deregister the terminal peripheral, thereby achieving the technical effect of deregistering the terminal peripheral and saving the storage resource.
1. A method for deregistering a terminal peripheral, comprising:
sending, by a gateway, a request message for deregistering a terminal peripheral to the terminal peripheral; and
deleting, by the gateway, registration information of the terminal peripheral stored by the gateway;
wherein before the gateway sends the request message for deregeristering the terminal peripheral to the terminal peripheral, the method further comprises:
receiving, by the gateway, the request message for deregeristering the terminal peripheral sent from a Machine-to-Machine/Man (M2M) service platform and/or an M2M application.
2. The method according to claim 1 , wherein the request message for deregistering the terminal peripheral carries indication information which indicates that this message is a request message for deregistering the terminal peripheral, and/or identification information which is used to identify the terminal peripheral of which the registration information needs to be deleted.
3. The method according to claim 1 , wherein after the gateway sends the request message for deregistering the terminal peripheral to the terminal peripheral, the method further comprises:
the terminal peripheral receiving the request message for deregistering the terminal peripheral;
the terminal peripheral deleting registration information of the gateway stored locally; and
the terminal peripheral returning a deregistration confirmation message to the gateway.
4. The method according to claim 3 , wherein deleting, by the gateway, registration information of the terminal peripheral stored by the gateway comprises:
based on that the gateway receives the deregistration confirmation message returned by the terminal peripheral, deleting, by the gateway, the registration information of the terminal peripheral stored by the gateway, wherein the deregistration confirmation message is a message which is returned to the gateway by the terminal peripheral after receiving the request message for deregistering the terminal peripheral.
5. The method according to claim 3 , wherein the registration information of the gateway comprises: a gateway identifier of the gateway, and/or an identifier and/or address allocated for the terminal peripheral by the gateway.
6. The method according to claim 1 , wherein deleting, by the gateway, the registration information of the terminal peripheral stored by the gateway further comprises:
when a predetermined time arrives, deleting, by the gateway, the registration information of the terminal peripheral stored by the gateway.
7. The method according to claim 1 , wherein the registration information of the terminal peripheral comprises: an identifier of the terminal peripheral and/or an address of the terminal peripheral.
8. The method according to claim 1 , wherein after the gateway deletes the registration information of the terminal peripheral locally stored by the gateway, the method further comprises:
sending, by the gateway, a deregistration confirmation message to the M2M service platform and/or the M2M application, wherein the deregistration confirmation message is used to indicate that the gateway has deregistered the terminal peripheral.
9. The method according to claim 1 , wherein the gateway is an M2M gateway in an M2M communication system.
10. A device for deregistering a terminal peripheral, located in a gateway, comprising:
a first sending element, configured to send, a request message for deregistering a terminal peripheral to the terminal peripheral; and
a deleting element, configured to delete registration information of the terminal peripheral stored by the gateway;
a receiving element, configured to, before the gateway sends the request message for deregeristering the terminal peripheral to the terminal peripheral, receive the request message for deregeristering the terminal peripheral sent from a Machine-to-Machine/Man (M2M) service platform and/or an M2M application.
11. The device according to claim 10 , wherein the deleting element is further configured to, based on that the gateway receives a deregistration confirmation message returned by the terminal peripheral, delete the registration information of the terminal peripheral stored by the gateway, wherein the deregistration confirmation message is a message which is returned to the gateway by the terminal peripheral after receiving the request message for deregistering the terminal peripheral and deleting registration information of the gateway stored by the terminal peripheral.
12. The device according to claim 10 , wherein the device further comprises:
a second sending element, configured to, after the gateway deletes the registration information of the terminal peripheral stored by the gateway, send a deregistration confirmation message to the M2M service platform and/or the M2M application, wherein the deregistration confirmation message is used to indicate that the gateway has deregistered the terminal peripheral.
