摘要： A mobile communication system with a packet switching function which enables sharing of radio resources among mobile stations, wherein a mobile station which has generated a request for communication quality assurance periodically sends a packet for requesting preferential use of a radio channel in order to prevent timeout of the state transition timer, timeout of which would cancel radio channel assignment to the mobile station and bring it into a dormant state if a certain period elapses without transmission or reception of a signal, so that it can remain in the active state and hold the radio channel continuously. In addition, when the mobile station requesting communication quality assurance moves from one cell to another or requests radio channel assignment, the base station controller controls the radio base station so that the mobile station can be assigned a radio channel by sending a priority request packet.

摘要： A communication control equipment connected between a computer and a network so as to perform protocol processing at a high speed, has a buffer memory connected between a computer interface circuit and a network interface circuit through a first path for data transfer, so as to temporarily store communication data, and a protocol processor connected between the computer interface circuit and the network interface circuit through a second path for control information transfer. The protocol processor is also connected to the buffer memory through a third path so as to effect protocol processing on the communication data within the buffer memory. The protocol processor includes a plurality of processor units connected in series in the second path so as to respond to control information received from the second path to make access to the buffer memory through the third path and to execute a first category of protocol processing necessary in normal data transfer on the communication data stored in the buffer memory. If protocol processing other than the first category of protocol processing on the communication data is necessary, the processor units supply the control information to the third path. The protocol processing also includes a second processor which operates as a backend processor for the processor units and which is connected to the third path so as to respond to the control information received from the third path to execute protocol processing other than the first category of protocol processing on the communication data stored in the buffer memory.

摘要： In a communication control equipment for transmitting data in an external predetermined memory to a network, there are provided a buffer memory unit for temporarily holding the data transferred thereto, a data transfer unit for performing a data transfer between the predetermined memory and the buffer memory unit, a unit for executing a protocol processing with regard to data held in the buffer memory unit, a control unit for controlling a transmission of the data processed by the protocol processing to the network, and a unit for producing a transmission start instruction at a start time instant within a range defined from a time instant when 1-packet data transfer from the predetermined memory to the buffer memory unit is commenced until a time instant when this data transfer is completed. The transmission start instruction is produced under a condition that the lower a data transfer speed from the predetermined memory to the buffer memory unit is relative to a transmission speed of the network, the later the start time instant is. A unit is also provided for causing the control unit to commence the transmission of the data processed by the protocol processing to the network at a later time instant during the time instant when the transmission start instruction is produced and the time instant when the protocol processing is terminated.

摘要： A plurality of packet gate ways (PGWS) are connected between a mobile communication system and an internet so that the corresponding IP subnetworks to those PGWs may be built. A visitor location register (VLR) operates to notify the PGW of location information of the mobile station (MS) and an IP address of a data terminal connected with the MS. If the notified IP address belongs to another IP subnetwork, the PGW notifies the corresponding PGW to that IP subnetwork of a fact that the local PGW is a destination. The PGW operates to manage the location information of the MS connected with the data terminal based on the notified content and perform the packet routing based on the managed content.
