Abstract
A mobility management switching center is for communicating with user equipment of a communication system that supports LTE or 3G, the mobility management switching center including a receiver that receives a session management signal from the user equipment; and a transmitter that transmits, when the session management signal is received, a restriction signal for instructing not to transmit a new session management signal to the user equipment.
Claims10
A mobility management switching center for communicating with user equipment of a communication system that supports LTE or 3G, the mobility management switching center comprising:
- a receiver that receives a session management signal from the user equipment;
- and
- a transmitter that transmits, when the session management signal is received, a restriction signal for instructing not to transmit a new session management signal to the user equipment.
A communication system that supports LTE or 3G and that includes a mobility management switching center and user equipment, wherein the mobility management switching center comprises:
- a first receiver that receives a session management signal from the user equipment;
- and
- a first transmitter that transmits, to the user equipment, a restriction signal for instructing not to transmit a new session management signal, when the session management signal is received, and
- wherein the user equipment includes
- a second receiver that receives the restriction signal;
- and
- a second transmitter that controls, when the restriction signal is received from the mobility management switching center, not to transmit a new session management signal to the mobility management switching center.
A communication control method to be executed in a communication system that supports LTE or 3G and that includes a mobility management switching center and user equipment, the communication control method comprising:
- a step of receiving, by the mobility management switching center, a session management signal from the user equipment;
- a step of transmitting, to the user equipment by the mobility management switching center, a restriction signal for instructing not to transmit a new session management signal when the session management signal is received;
- a step of receiving the restriction signal by the user equipment;
- and
- a step of controlling, by the user equipment, not to transmit a new session management signal to the mobility management switching center when the restriction signal is received from the mobility management switching center.
