when the timer MStime_duration runs, the terminal stops receiving data sent by the gateway of the first operator network, adjusts the frequency band of the receiver, monitors whether a second access management functional entity of the second operator network has paging information sent to the terminal or not; if the paging message sent to the terminal by the second access management functional entity is not received at the end of the running of the timer MStime_duration, the terminal adjusts the frequency band of the receiver and resumes receiving the data sent by the gateway of the first operator network; at this time, the terminal needs to adjust the running duration of the timer mstimer_duration in the following manner:
if Temp_ monitoring duration 1×monitor factor is less than or equal to monitor Max_duration, setting a parameter Temp_ monitoring duration 2 =Temp_ monitoring duration 1 ×monitor factor;
if Temp_ monitoring duration 1×monitor factor > monitor Max_duration, the parameter Temp_ monitoring duration 2 =Temp_ monitoring duration 1 is set;
setting the duration of the timer MStime_duration as the value of Temp_ monitoring duration 2; in addition, the setting parameter temp_ monitoring duration 1 =temp_ monitoring duration 2;
when the timer MStime_duration runs, if a paging message sent by the second access management function entity is received and the service type indicated in the paging message is voice service, the terminal sends a session termination message to the first access management function entity;
the first receiving management function entity receives the session termination message, then terminates the session process between the terminal and the gateway of the first operator network, and then sends a session termination response message to the terminal;
after receiving the session termination response message, the terminal sends a service request message to a second access management functional entity; simultaneously stopping the period timer MSTimer_period and the timer MSTimer_duration; setting a parameter temp_ monitoring duration 1 = monitoring duration;
and after receiving the service request message, the second access management functional entity establishes a session process for the terminal and the gateway of the second operator network.

starting a period timer MSTimer_period, wherein the value of the period timer MSTimer_period is set to be the value of monitoring period; setting the value of the parameter Temp monitoring duration 1 to the value of monitoring duration; starting a timer MStimer_duration, wherein the value of the timer_duration is set to be the value of the Temp_ monitoring duration;
stopping receiving data sent by the first access management functional entity when the timer MStime_duration runs; monitoring whether the second access management functional entity sends a paging message or not;
when the timer MStime_duration expires, if the paging message sent by the second access management function entity is not received, recovering to receive the data sent by the first access management function entity; if the product of the value of Temp_ monitoring duration 1 and the monitor factor is less than or equal to the value of monitor Max_duration, setting the value of parameter Temp_ monitoring duration 2 to be the product of the value of Temp_ monitoring duration 1 and the monitor factor; if the product of the value of Temp_ monitoring duration 1 and the monitor factor is greater than the value of monitor Max_duration, setting the value of parameter Temp_ monitoring duration 2 to be the value of Temp_ monitoring duration 1; setting the value of the timer MStimer_duration to the value of the Temp_ monitoring duration 2; setting the value of Temp monitoring duration 1 to the value of Temp monitoring duration;
when the timer MStime_duration runs, if a third paging message sent by a second access management function entity is received and the third paging message indicates voice service, a session termination message is sent to the first access management function entity; stopping the periodic timer MSTimer_period, and stopping the timer MSTimer_duration; the value of Temp monitoring duration 1 is set to the value of monitoring duration.
10. A method of multi-network communication management, characterized in that the method is applied to the system of any one of claims 1-9, the method comprising:
the terminal sends a first attachment request message to a first access management functional entity, wherein the first attachment request message comprises a multi-user identification card indication and an international mobile equipment identification code; sending a second attach request message to a second access management function entity, wherein the second attach request message comprises the multi-user identification card indication and the international mobile equipment identification code; the multi-user identification card indication is used for indicating the terminal to use a plurality of user identification cards; the international mobile equipment identification code is used for identifying the terminal;
the first access management functional entity receives the first attachment request message and locally sets first multi-user identification card management information; the first multiuser identification card management information comprises the multiuser identification card indication, the international mobile equipment identification code and a first voice service state, wherein the first voice service state is used for indicating whether the terminal and the first access management functional entity are in voice service;
the second access management functional entity receives the second attachment request message and locally sets second multi-user identification card management information; the second multiuser identification card management information comprises the multiuser identification card indication, the international mobile equipment identification code and a second voice service state, wherein the second voice service state is used for indicating whether the terminal and the second access management functional entity are in voice service;
the first access management functional entity receives a downlink data notification message sent by a gateway, wherein the downlink data notification message comprises a service type and the international mobile equipment identification code; when the service type is voice service, acquiring a second voice service state of the terminal, and sending a first paging message to the terminal or sending a response message to the gateway according to the first multi-user identification card management information and the second voice service state; and when the service type is data service, sending a second paging message to the terminal.
