摘要:
In a method and device which prevent unnecessary accounting from being performed when a communication deteriorated state occurs in a mobile terminal, a communication deteriorated state is detected in a state where a location registration is performed to a mobile radio communication network, a duration of the communication deteriorated state is detected, and cut of the duration from a duration of accounting is notified to the mobile radio communication network. With the notification, the mobile radio communication network changes accounting for the mobile terminal in the communication deteriorated state. Also, as the above-mentioned communication deteriorated state, there is e.g. a call disable state, a communication disable state during a voice/packet communication, or a communication disconnection state.
摘要:
In a method and a device, and a mobile communication system by which a connection switchover between wireless network control devices can be performed with a connected base station being maintained in order to avoid a congestion when the congestion occurs in one of the wireless network control devices within a mobile communication network, network management information indicating congestion states of all wireless network control devices is acquired from a core network within the mobile communication network, a wireless network control device list is prepared in which a higher priority is assigned to the wireless network control devices in ascending order of congestion degree based on the network management information when a call request is received from one mobile terminal through a base station, the wireless network control device list is notified to the mobile terminal through the base station, and the mobile terminal is enabled to select one of the wireless network control devices as a connecting destination.
