Abstract
The present invention relates to a method for controlling an overload of a network, which may be generated due to a service request of a terminal in a mobile communication system of machine type communication (MTC). The invention controls a network overload and efficiently use network resources, by requesting activation of a particular MTC function to the network on the basis of information on changes in unnecessary MTC functions, without allowing a terminal to request (for example, attach request) the unnecessary MTC functions.
Claims10
A method of controlling a network overload in a mobile communication system, the method comprising:
- receiving and storing, by a terminal, information about a control of the network overload from a network node;
- determining, by the terminal, whether a service request to the network node is to be rejected or accepted by analyzing the stored information about the control of the network overload;
- and
- transmitting, by the terminal, a message requesting a service to the network node when it is determined that the network node is to accept the service request,
- wherein the information about the control of the network overload includes information indicating an activation state of machine type communication (MTC) features associated with the terminal.
A method of controlling a network overload in a mobile communication system, the method comprising:
- receiving, by a network node, a message requesting a service from a terminal;
- receiving, by the network node, information about machine type communication (MTC) features of the terminal from a subscriber registration server;
- determining, by the network node, whether to reject or accept a service request of the terminal by considering the received information about the MTC features of the terminal, a network condition, and an operator policy;
- and
- transmitting, by the network node, a message of accepting or rejecting the service request together with information about a control of the network overload to the terminal, based on the determination.
A mobile communication terminal comprising:
- a transmission and receiving unit configured to request a service to a network node and configured to receive, from the network node, information about a state of machine type communication (MTC) features, information about a cause for rejection to a request for the service, and information about MTC features currently capable of being activated;
- a storage unit configured to store the information about the state of MTC features, the information about the cause for rejection to the request for the service, and the information about the MTC features currently capable of being activated, received from the network node;
- and
- a controller configured to control a network overload by determining whether to request the service to the network by considering the received information such that the network overload is not generated.
