摘要:
There are a wireless access network comprising a radio network gateway apparatus (101), radio access network control apparatus (102a), (102b) and a base stations (103a), (103b) and a terminal (104) accommodated in the wireless access network and when the terminal (104) enters into a new cell B, a packet data is transmitted from the source radio access network control apparatus (102a) to the target radio access network control apparatus (102b). Further, when the terminal (104) switches the radio access network control apparatus (102) with which the terminal (104) communicates, the target radio access network control apparatus (102b) switches a transmission line of a data to be transmitted to the terminal (104) from a wireless data to a packet data in the source radio access network control apparatus (102a), and from the source packet data to a target packet data in a synchronized manner at each timing. This reduces traffic which occurs when switching a radio access network control apparatus to be communicated while the terminal moves between cells and prevent packet interruption in a wireless access network providing packet transmission service.
摘要:
Provided is a display controller which prevents the duplication of functional parts and the duplication of processes, and displays dynamic content on a plurality of displays. A portable terminal (400) used as the controller has a shared dynamic image decoder (409) which decodes the dynamic content and stores the decoded dynamic content in a frame buffer (406) used by the terminal, a buffer transfer unit (408) which sends the dynamic content stored in the frame buffer (406) used by the terminal to a frame buffer (411) used by an external monitor, a terminal display unit (407) which displays the dynamic content stored in the frame buffer (406) used by the terminal on the display of the terminal, and an external monitor interface (412) which displays the dynamic content stored in the frame buffer (411) used by the external monitor on an external monitor (500).
摘要:
A system of access control in a data communication network comprising of a privacy unaware Guest Device, a privacy unaware Slave device, a PN Server and a Master Device wherein the access of a privacy unaware Slave device by a privacy unaware Guest Device is restricted by a PN Server, which intercepts all session initiations concerned with the Slave Device. A method of access control of the system comprises the steps of Access request by Guest Device privacy mode processing by PN Server privacy decision processing by Master Device; and privacy response processing by PN Server.
