Base Station Subsystem The Base Station Subsystem (BSS) is the section of a GSM network which is responsible for actually transmitting and receiving radio signals from the mobile phone. The BSC handles allocation of radio channels, receives measurements from the mobile phones, controls handovers from BTS to BTS (except in the case of an inter-MSC handover in which case control is in part the responsibility of the Anchor MSC). A key function of the BSC is to act as a concentrator where many different low capacity connections to BTSs (with relatively low utilisation) become reduced to a smaller number of connections towards the MSC (with a high level of utilisation). www.encyclopedia-1.com /b/ba/base_station_subsystem.html

Patent 5708657: Apparatus for interfacing mobile switching center(MSC) with base station controller(BSC) of CDMA mobile system A base station controller interface of the CDMA mobile switching center as in claim 1, wherein each of the nodes of said local subsystem network is accompanied with the signal for transmitting the TD-bus in triplicate. The control signal for processing the call is accomplished by using the inner communication message protocol which is connected in the EIA-422 interfacing mode to the call control processor of the base station controller. The subordinate processor performs the control of the device by receiving all of the control signals from the access switching processor through the local subsystem network, or is the controlling processor which functions to transmit in the IPC form the device condition through the local subsystem network. www.freepatentsonline.com /5708657.html

GSM base station field trials After testing several implementations of the power control algorithm, a balance was reached that smoothed the mobile's changes in transmit power, while still increasing the mobile phone's power at a high enough rate to match the movement of the mobile traveling in a car away from the base station at high speeds. In normal operation, the base station does not log all of the power measurements during a phone call, to reduce the load on the base station as well as reduce the amount of information in the logs. This was the first field trial of the company's software GSM base station in a live outdoor environment. rfdesign.com /mag/radio_field_trials_allsoftware

Planning of the base station interconexion network Similarly, GSM controllers and switches and TACS 900-A switches are both referred to as Base Station Switches and/or Controllers (BSSC), as illustrated in figure 1 (this nomenclature is neither standard nor in general use). In the GSM network [2] each base station is connected to a base station controller, which is linked in turn to a switching centre. Optimization of the transmission infrastructure used to connect base stations with the other terrestrial network elements can be of considerable help in reducing the overall cost of the network to a mobile telephone operator. www.tid.es /presencia/publicaciones/comsid/ing/articulos/vol812/planning/planning.html

Patent 5978677: Migration of routing number selection to the base station controller of a cellular telephone network The base station controller then assigns an appropriate one of its routing numbers (for example, a temporary location directory number or a roaming number), and responds back to the originating switching node via the home location register and the visited switching node with the assigned routing number. Delivery of the call to the mobile station is then accomplished by establishing a trunk connection with a base station controller connected to a base station currently serving the mobile station. The base station controller then assigns an appropriate one of its routing numbers, and responds back to the originating switching node via the home location register and the visited switching node with the assigned routing number. www.freepatentsonline.com /5978677.html

Base stations are deployed in different locations around the local center office. www.discover.uottawa.ca /~leizj/Experiences/MasterThesis/BSC.html

PLMN - User services and terminals: Introduction Every cell employs at least one channel as a control channel, on which the base station continuously transmits an identifying signal that is used by the mobiles to lock into that particular cell. Duplex mode is employed for traffic over radio access, meaning that the base stations and the mobiles must be capable of simultaneous transmission and reception, requiring two frequency ranges sufficiently separated from one another. Control channels are also used for paging calls; if the called mobile is in the cell, it will respond over the same (or another) channel. www.ericsson.com /support/telecom/part-d/d-1-1.shtml

Method of supporting power control on a DCCH in a base station transceiver system and a base station controller - US Patent 6728551 If this slow forward power control mode is set, an MS transmits a QIB on a reverse pilot channel and a BS (a BTS and a BSC) determines a threshold for the forward power control based on the QIB. Therefore, the MS generates a power control command based on the null frame received from the BS and transmits it on a reverse pilot channel. This operation may occur between the BSC 32 (BSC-SDU 34) and a BTS 36 in the source BS 30, or a BSC 42 and a BTS 44 in the target BS 40. www.patentstorm.us /patents/6728551.html

bsc.html GSM BSC is kind of a relay element, ie it does not spontanously begin to communicate with other elements, but merely passes messages from one interface to another, maybe modifying them somehow. BSC can then analyze these messages, and decide whether a handover is needed. The user can also control the behaviour of individual vtask by setting its internal variables, states and timer values, and sending control messages to it. www.soberit.hut.fi /tik-76.115/95-96/palautukset/Mobiili/js/bsc/bsc.html

BSC - Base Station Controller The BSC is the functional entity within the GSM architecture that is responsible for RR (Radio Resource) allocation to a MS (Mobile Station), frequency administration and handover between BTS (Base Transceiver Station) controlled by the BSC. If this is the case there is no requirement for the Abis interface, and a preparatory interface to map signalling and traffic destined for the MS may be employed. The BSC function may be physically located with the BTS. www.mpirical.com /companion/GSM/BSC.htm

PLMN - Network planning: Network architecture Base stations can use over-capacity in an existing transport network. Wherever possible, a BSC's coverage should be chosen such that the boundaries run across areas with low handover intensity. Since the mobiles and the network can handle both full rate and half rate at the same time, the capacity of a cell will vary depending on the types of mobile that are within the cell boundaries at the moment. www.ericsson.com /support/telecom/part-d/d-10-5.shtml

Overview of GSM (extended abstract) The Base Station Subsystem is composed of two parts, the Base Transceiver Station (BTS) and the Base Station Controller (BCS). TDMA frames of a particular carrier frequency are numbered, and both the mobile station and the base station are synchronized on this number. There is logically one HLR per GSM network, although it may be implemented as a distributed database. ccnga.uwaterloo.ca /~jscouria/trio.html

icon,Seventh IEEE International Conference on Networks (ICON'99) In this paper, we first describe the architecture of base station (BS) in the CDMA mobile system (CMS) and then model one base station controller group (BSCG) as a queuing network. Based on these results, we present the call handling capacity of one BSC group for mobile originated calls in the CMS(CDMA Mobile System). As the transmission technology for the traffic data from TCE to BSC during the call conversation time, we consider two kinds of transmission schemes such as the frame non-staggering scheme and the frame staggering scheme. csdl.computer.org /comp/proceedings/icon/1999/0243/00/02430279abs.htm
