A method for trigger management by a Common Service Entity, comprising: sending, by the CSE, a trigger request to a network element of a bearer network, wherein the trigger request carries following information: a trigger message, an external identifier of the CSE, an identifier of a triggered device and a resource identifier of a trigger resource corresponding to the trigger request, wherein the trigger resource is a resource used for triggering an establishment of a connection between the CSE and the triggered device; receiving, by the CSE, a trigger response, which corresponds to the trigger request, sent by the network element of the bearer network; and updating, by the CSE, a first attribute of the trigger resource according to the trigger response; wherein the first attribute at least comprises a trigger status of the trigger resource; the trigger response carries the following information: the resource identifier of the trigger resource and a request status; wherein updating, by the CSE, the first attribute of the trigger resource according to the trigger response comprise the following implementation forms: when the request status indicates success, setting, by the CSE according to the resource identifier, the trigger status as being confirmed by the bearer network or backoff-for-trigger; when the request status indicates that a sending frequency of the trigger message exceeds a standard, setting, by the CSE according to the resource identifier, the trigger status as backoff-for-trigger; and when the request status indicates one of the following information: a temporary error, an invalid load, an invalid device identifier, an invalid CSE identifier, non-authorized, invalid validity time, service unavailability and quota exceeding, setting, by the CSE according to the resource identifier, the trigger status as failure. sending, by the CSE, a trigger request to a network element of a bearer network, wherein the trigger request carries following information: a trigger message, an external identifier of the CSE, an identifier of a triggered device and a resource identifier of a trigger resource corresponding to the trigger request, wherein the trigger resource is a resource used for triggering an establishment of a connection between the CSE and the triggered device; receiving, by the CSE, a trigger response, which corresponds to the trigger request, sent by the network element of the bearer network; and updating, by the CSE, a first attribute of the trigger resource according to the trigger response; wherein the first attribute at least comprises a trigger status of the trigger resource; the trigger response carries the following information: the resource identifier of the trigger resource and a request status; wherein updating, by the CSE, the first attribute of the trigger resource according to the trigger response comprise the following implementation forms: when the request status indicates success, setting, by the CSE according to the resource identifier, the trigger status as being confirmed by the bearer network or backoff-for-trigger; when the request status indicates that a sending frequency of the trigger message exceeds a standard, setting, by the CSE according to the resource identifier, the trigger status as backoff-for-trigger; and when the request status indicates one of the following information: a temporary error, an invalid load, an invalid device identifier, an invalid CSE identifier, non-authorized, invalid validity time, service unavailability and quota exceeding, setting, by the CSE according to the resource identifier, the trigger status as failure. when the request status indicates success, setting, by the CSE according to the resource identifier, the trigger status as being confirmed by the bearer network or backoff-for-trigger; when the request status indicates that a sending frequency of the trigger message exceeds a standard, setting, by the CSE according to the resource identifier, the trigger status as backoff-for-trigger; and when the request status indicates one of the following information: a temporary error, an invalid load, an invalid device identifier, an invalid CSE identifier, non-authorized, invalid validity time, service unavailability and quota exceeding, setting, by the CSE according to the resource identifier, the trigger status as failure.
