A call processing method, comprising: receiving, by a call server, a first call request of a calling terminal for a called terminal; triggering, by the call server according to the first call request, a mobility management entity to control a base station to page the called terminal; performing, by the call server, when receiving a paging response message that is sent by the mobility management entity and that is used to indicate that the called terminal is in a power saving state and cannot be paged by the base station, call waiting according to the paging response message; wherein call waiting according to the paging response message comprises: sending, by the call server, an instruction message to the calling terminal used to instruct the calling terminal to terminate the current call request to the called terminal, wherein the current call request is the first call request; terminating, by the call server, the current call request, and recording information about the current call request; waiting, by the call server, for the called terminal to be paged by the base station; and when receiving, by the call server, in call waiting, addressing information of the called terminal sent by the mobility management entity, wherein the addressing information is used to indicate that the called terminal is woken up from the power saving state and is paged by the base station, then sending, by the call server, a second call request to the calling terminal and to the called terminal according to the previously recorded call information, wherein the second call request is used to instruct to establish a session connection between the calling terminal and the called terminal; and establishing, by the call server, the session connection between the calling terminal and the called terminal. receiving, by a call server, a first call request of a calling terminal for a called terminal; triggering, by the call server according to the first call request, a mobility management entity to control a base station to page the called terminal; performing, by the call server, when receiving a paging response message that is sent by the mobility management entity and that is used to indicate that the called terminal is in a power saving state and cannot be paged by the base station, call waiting according to the paging response message; wherein call waiting according to the paging response message comprises: sending, by the call server, an instruction message to the calling terminal used to instruct the calling terminal to terminate the current call request to the called terminal, wherein the current call request is the first call request; terminating, by the call server, the current call request, and recording information about the current call request; waiting, by the call server, for the called terminal to be paged by the base station; and when receiving, by the call server, in call waiting, addressing information of the called terminal sent by the mobility management entity, wherein the addressing information is used to indicate that the called terminal is woken up from the power saving state and is paged by the base station, then sending, by the call server, a second call request to the calling terminal and to the called terminal according to the previously recorded call information, wherein the second call request is used to instruct to establish a session connection between the calling terminal and the called terminal; and establishing, by the call server, the session connection between the calling terminal and the called terminal. sending, by the call server, an instruction message to the calling terminal used to instruct the calling terminal to terminate the current call request to the called terminal, wherein the current call request is the first call request; terminating, by the call server, the current call request, and recording information about the current call request; waiting, by the call server, for the called terminal to be paged by the base station; and when receiving, by the call server, in call waiting, addressing information of the called terminal sent by the mobility management entity, wherein the addressing information is used to indicate that the called terminal is woken up from the power saving state and is paged by the base station, then sending, by the call server, a second call request to the calling terminal and to the called terminal according to the previously recorded call information, wherein the second call request is used to instruct to establish a session connection between the calling terminal and the called terminal; and establishing, by the call server, the session connection between the calling terminal and the called terminal.
