2819 results about "Radio access network" patented technology

A radio access network (RAN) is part of a mobile telecommunication system. It implements a radio access technology. Conceptually, it resides between a device such as a mobile phone, a computer, or any remotely controlled machine and provides connection with its core network (CN). Depending on the standard, mobile phones and other wireless connected devices are varyingly known as user equipment (UE), terminal equipment, mobile station (MS), etc. RAN functionality is typically provided by a silicon chip residing in both the core network as well as the user equipment. See the following diagram...

Automatic building of neighbor lists in mobile system

In a radio access network (24) a femto radio base station (28f) comprises a resident receiver (54) which acquires system information broadcast in a radio access network (24). At least part of the system information is used for building, at the femto radio base station (28f), a neighbor data structure (59) comprising information for neighboring cells. The neighbor data structure (59) is then used for building a neighbor list. The neighbor list is subsequently transmitted from the femto radio base station (28f) to a user equipment unit (30) served by the femto radio base station (28f). In some example embodiments and modes, the femto radio base station (28f) reports the neighbor data structure to a network node (26, 100) other than the femto radio base station. The other node (26, 100) uses the neighbor data structure for building the neighbor list at the other node. In some example embodiments and modes, acquisition of the system information comprises scanning a surrounding macro coverage area of the femto radio base station for obtaining cell identity information for detected cells. In other example embodiments and modes, the acquisition of the system information can additionally comprise camping on a macro cell and using/consulting at least one system information block in the camped-on macro cell is consulted/used for obtaining information about at least one neighboring cell.

System and method for optimizing network capacity in a cellular wireless network

A system and method is disclosed for increasing the efficiency of a cellular communication network, reduce ongoing operating costs and increase revenue. According to one aspect, a method is disclosed for increasing the efficiency of a cellular communication network whereby network capacity in the radio access network (RAN) and baseband processing for wireless connections are dynamically adjusted to automatically provision sufficient bandwidth and baseband processing capacity in response to changes in the network. The method is further extended by implementing policy management which allows wireless carriers to develop and implement network based policies to automatically increase or decrease the amount of processing resources and network bandwidth required from any cell site, hub or mobile switching office. According to another aspect, network efficiency is enhanced by utilizing a novel cellular network infrastructure. RF signals from cell site antennas of various technology types are demodulated, digital bit information is extracted from the RF signals, processed, and groomed into Gigabit Ethernet/Resilient Packet Ring (GigE/RPR) or Ethernet over copper traffic flows using specific Quality of Service (QoS) priorities. The GigE/RPR traffic flows are routed to hub sites or mobile switching offices, at which point the packetized information is extracted and converted to RF signals that are equivalent to the signals that were received at the antenna. The RF signals are sent over coaxial cable to a network hub including a pool of Base Transceiver Stations (BTSs) (or Node Bs). The hub is coupled to one or more mobile switching offices via a second fiber optic ring.

Technique for synchronizing multiple access controllers at the head end of an access network

A technique is described which may be used to synchronize a plurality of different access controllers which control a plurality of distinct ports at the Head End of an access network. In the context of a cable network, the technique of the present invention may be used to synchronize desired upstream and/or downstream channels across different line cards within a Cable Modem Termination System (CMTS). The technique involves utilizing a master time reference device which maintains and updates a current time reference, and periodically distributes synchronization signals to desired line cards in the system in order to synchronize these line cards. In a specific embodiment, the synchronization signals include current timestamp data generated from the master time reference device and distributed to all (or selected) line cards in the system. A slave time reference device on each of the line cards receives the periodic synchronization updates and uses the synchronization data to remain synchronized with the master time reference device. There are also provisions in this protocol to allow for hot insertion and removal of line cards, software reset or loading of the master and/or slave time reference devices, and redundant master time reference devices, including master time reference device fault detection and automatic fail over.

Cloud platform supporting fusion network service and operating method thereof

The invention relates to a cloud platform supporting fusion network service and an operating method thereof. The cloud platform is provided with a plurality of hardware and software resources, and is connected with three access networks of a telecommunication network, an interconnection network and a broadcasting and television network respectively through three core networks of operators of the three networks and the corresponding communication protocol to allow platform users (including the operators of the three networks or service providers and the like) to rent platform resources according to respective requirements to deploy respective services and operational capabilities. The cloud platform has a layered structure, and is provided with a platform management layer, a service execution layer, a resource virtualization and management layer and a hardware resource layer respectively from top to bottom, and in an interactive mode among the layers, an upper-layer module uses the function provided a lower-layer module in a mode of interface call. The cloud platform supports the platform users to adjust the rent resources dynamically and conveniently according to actual requirements, and simultaneously, provides the access capability on the resources of the three networks and convenience for the development and operation of the fusion network service by the platform users.
