An information sending method, executed by a mobile terminal, wherein the mobile terminal has at least a first operation mode and a second operation mode, wherein the first operation mode is different from the second operation mode, and the method comprises: when the mobile terminal is in the first operation mode, receiving at least one first notification message that is related to a first token and sent by a push server, wherein the first token is a first identifier of the mobile terminal while in the first operation mode and that is used for a push service; sending a first instruction message to the push server when the mobile terminal switches from the first operation mode to the second operation mode, wherein the first instruction message is used to instruct the push server to temporarily store at least one second notification message related to the first token; and receiving at least one third notification message that is related to a second token and sent by the push server, wherein the second token is a second identifier of the mobile terminal while in the second operation mode and that is used for a push service; wherein after the sending a first instruction message to the push server, the method further comprises: sending a second registration request to the push server, wherein the second registration request is used to request the push server to generate the second token, and the second token is used for the push service of the mobile terminal in the second operation mode; receiving and saving the second token sent by the push server; and sending the second token to an application server, wherein the second token is used by the application server to send the at least one third notification message to the push server according to the second token; wherein after the receiving and saving the second token sent by the push server, the method further comprises: sending a second instruction message to the push server when the mobile terminal exits the second operation mode, wherein the second instruction message is used to instruct the push server to destroy the second token. when the mobile terminal is in the first operation mode, receiving at least one first notification message that is related to a first token and sent by a push server, wherein the first token is a first identifier of the mobile terminal while in the first operation mode and that is used for a push service; sending a first instruction message to the push server when the mobile terminal switches from the first operation mode to the second operation mode, wherein the first instruction message is used to instruct the push server to temporarily store at least one second notification message related to the first token; and receiving at least one third notification message that is related to a second token and sent by the push server, wherein the second token is a second identifier of the mobile terminal while in the second operation mode and that is used for a push service; wherein after the sending a first instruction message to the push server, the method further comprises: sending a second registration request to the push server, wherein the second registration request is used to request the push server to generate the second token, and the second token is used for the push service of the mobile terminal in the second operation mode; receiving and saving the second token sent by the push server; and sending the second token to an application server, wherein the second token is used by the application server to send the at least one third notification message to the push server according to the second token; sending a second registration request to the push server, wherein the second registration request is used to request the push server to generate the second token, and the second token is used for the push service of the mobile terminal in the second operation mode; receiving and saving the second token sent by the push server; and sending the second token to an application server, wherein the second token is used by the application server to send the at least one third notification message to the push server according to the second token; wherein after the receiving and saving the second token sent by the push server, the method further comprises: sending a second instruction message to the push server when the mobile terminal exits the second operation mode, wherein the second instruction message is used to instruct the push server to destroy the second token.
