摘要:
The radio access network for allowing to construct a system abundant in scalability in a W-CDMA mobile communication system. A RNC in the radio access network is physically separated into a C plane control equipment for controlling signaling and a U plane control equipment for processing user data, where the user data is transferred between a mobile terminal and a host device via only the U plane control equipment and a control signal is terminated by the U plane control equipment and the C plane control equipment. This allows a system abundant in scalability to be constructed, and even in the case of soft handover across the C plane control equipments, also enables the continuous use of the same U plane control equipment, thereby eliminating the conventional connection path for connecting between RNCs and preventing delay due to passing through the RNCs.
摘要:
A radio communication system which automatically selects a communication path having a higher speed is provided when a plurality of communication paths having a different speed from each other are available for data transmission between the radio terminal and the base station control equipment. The radio terminal receives a data frame and sends back an ACK signal for the data frame via the communication path through which the data frame has been received. At this time, the radio terminal acquires data of the frame with a sequence number having received at the first time, and if the frame with the same sequence number is received later, the frame is discarded. However, the ACK signal is sent back in respective cases. The base station control equipment transmits a first data frame to the radio terminal via the plurality of communication paths and transmits subsequent data frames to the radio terminal via one communication path through which the ACK signal for the first data frame has arrived the earliest.

摘要:
A mobile communications system has a subscriber database, located in a second mobile communications network, which manages subscriber information of a mobile terminal and registers location information in response to a location registration request made by the mobile terminal to the second mobile communications network, and registers location information in response to a location registration request made by the mobile terminal to a first mobile communications network, and a call control server which changes a caller number in a call request to a telephone number assigned for the second mobile communications network and transmits the call request to a connection destination upon receiving the call request from the mobile terminal which is located under the first mobile communications network.
