Patent application number | Description | Published |
20110312313 | MOBILE COMMUNICATION SYSTEM, RADIO NETWORK CONTROLLER AND METHOD - A radio network controller connected to multiple exchanges in a mobile communication system includes an exchange side interface configured to communicate with the multiple exchanges, a mobile station side interface configured to receive a call connection signal from a mobile station via a radio base station, a management unit configured to manage congestion levels indicative of congestion states of the respective exchanges and a control unit. The exchange side interface acquires the congestion levels from the respective exchanges, and the control unit determines to transfer a predefined ratio of call connection signals destined for an exchange having a higher congestion level to an exchange having a lower congestion level, the ratio being predefined corresponding to the congestion level. | 12-22-2011 |
20120099528 | RADIO NETWORK CONTROL DEVICE, PACKET SWITCHING DEVICE, CIRCUIT SWITCHING DEVICE, AND INFORMATION REPORTING METHOD - A radio network control device in a mobile communication network includes a first communication unit communicating with a packet switching device in a packet switched domain; a second communication unit communicating with a circuit switching device in a circuit switched domain; and a management unit transmitting information to the packet switching device, the information indicating whether the radio network control device can correctly communicate with the circuit switching device. The management unit transmits the information when transmitting a signal to the packet switching device via the first communication unit, the signal indicating whether the radio network control device can correctly communicate with the packet switching device, or when transmitting an attach request signal to the packet switching device via the first communication unit, the attach request signal being transmitted from a mobile station. | 04-26-2012 |
20120207091 | MOBILE COMMUNICATION METHOD AND RADIO ACCESS NETWORK APPARATUS - A mobile communication method according to the present invention includes the steps of: after a mobile station UE having RRC connection with the radio network controller RNC gets out of the coverage of the mobile communication system of WCDMA scheme, performing location registration to the mobile communication system of LTE scheme, issuing a notification to the radio network controller RNC by the exchange apparatus SGSN upon reception of predetermined signal, the notification implying that the mobile station UE performs the location registration to the mobile communication system of LTE scheme; and the radio network controller RNC releasing the resources for RRC connection without transmitting a signal to release the resources to the mobile station UE in response to the notification from the exchange apparatus SGSN. | 08-16-2012 |
20120208585 | MOBILE COMMUNICATION METHOD, RADIO ACCESS NETWORK APPARATUS AND EXCHANGE APPARATUS - A mobile communication method according to the present invention includes step A of instructing, by a radio access network apparatus of a first communication scheme, a mobile station having first radio connection established with the radio access network apparatus of the first communication scheme to switch to a mobile communication system of a second communication scheme, and step B of notifying the mobile station of a priority by the mobile communication system of the second communication scheme using a predetermined signal after the mobile station establishes second radio connection with a radio access network apparatus of the second communication scheme, the priority used to determine a communication system for camping-on by the mobile station. | 08-16-2012 |
20120263146 | MOBILE COMMUNICATION SYSTEM, RADIO CONTROL APPARATUS, CORE NETWORK APPARATUS, MOBILE COMMUNICATION TERMINAL AND MOBILE COMMUNICATION METHOD - The first communication system is configured to determine whether or not to provide information that instructs the UE | 10-18-2012 |
20120289238 | RADIO NETWORK CONTROLLER AND WIRELESS COMMUNICATION METHOD - A radio network controller for a wireless communication system, in which a dedicated channel and an enhanced dedicated channel are switched and assigned for an uplink for each call, includes a throughput estimation unit that estimates a throughput, wherein the throughput is expected when the enhanced dedicated channel is assigned to a call to be transmitted by a mobile station to which the dedicated channel has been assigned and/or to a call to be transmitted by a mobile station that initiates a communication; a packet access scheme selection unit that selects the enhanced dedicated channel, when the throughput estimated by the throughput estimation unit is greater than or equal to a predetermined threshold value; and a packet access scheme setting unit that sets the enhanced dedicated channel, when the packet access scheme selection unit selects the enhanced dedicated channel. | 11-15-2012 |
