A resource management method of a machine type communication application, comprising: a local common service entity receiving a registration updating request message sent by a machine to machine, M2M, application, wherein, the registration updating request message carries remote registration parameters of the M2M application; managing remote registration of the M2M application according to an instruction of the remote registration parameters; and returning a registration updating response to the M2M application; wherein the remote registration parameters comprise a remote registration list, and the remote registration list comprises an identifier of a remote CSE to which the M2M application is to be registered, and, wherein, said managing remote registration of the M2M application according to an instruction of the remote registration parameters comprises: comparing the remote registration list with a registered remote CSE list of the M2M application stored locally; judging whether in the remote registration list, there is an identifier of a remote CSE which does not appear in the registered remote CSE list; if yes, sending a remote registration request to the remote CSE, registering the M2M application to the remote CSE, and adding the identifier of the remote CSE to which the M2M application is successfully registered into the registered remote CSE list; characterised in that said managing remote registration further comprises judging whether in the registered remote CSE list, there is an identifier of a remote CSE which does not appear in the remote registration list; if yes, sending a remote un-registration request to the remote CSE, un-registering the M2M application from the remote CSE, and deleting the identifier of the remote CSE from which the M2M application is successfully un-registered from the registered remote CSE list. a local common service entity receiving a registration updating request message sent by a machine to machine, M2M, application, wherein, the registration updating request message carries remote registration parameters of the M2M application; managing remote registration of the M2M application according to an instruction of the remote registration parameters; and returning a registration updating response to the M2M application; wherein comparing the remote registration list with a registered remote CSE list of the M2M application stored locally; judging whether in the remote registration list, there is an identifier of a remote CSE which does not appear in the registered remote CSE list; if yes, sending a remote registration request to the remote CSE, registering the M2M application to the remote CSE, and adding the identifier of the remote CSE to which the M2M application is successfully registered into the registered remote CSE list; characterised in that said managing remote registration further comprises judging whether in the registered remote CSE list, there is an identifier of a remote CSE which does not appear in the remote registration list; if yes, sending a remote un-registration request to the remote CSE, un-registering the M2M application from the remote CSE, and deleting the identifier of the remote CSE from which the M2M application is successfully un-registered from the registered remote CSE list.
