Description
The present invention relates to wireless communication system.More specifically, the present invention relates to a wireless communication system and a kind of structure that wired communication system combines.
The requirement to personal communication of Cun Zaiing everywhere forces new development of internet technology, with adapt in a plurality of cities, wide region and even the mobile voice and the digital subscriber that between country, move.Relate to communication system widely and the technology of utilizing open air interface for " wireless " used in this specification, the system that connects with land line is opposite.Mobile phone, cell phone, Wireless Local Loop, paging and PCS Personal Communications System (PCS) are to prepare to be applicable to some examples of wireless communication system of the present invention.
For example, consider typical cell phone system shown in Figure 1.In order to provide radio communication in a specific geographic area, this cell phone system has disposed the comprehensive network of a plurality of base stations (BS1-BS4) that are enough to cover this zone.Then, a mobile switching centre (MsC) is received in these base stations.This mobile switching centre is between public switch telephone network (PSTN) and these base stations and provide connection between all wireless users after all in system.PSTN has constituted the part of global communication network, and it has connected traditional (wired) telephone switching center (central office) and other MSC that spreads all over the world.
Radio Link and base station communication that the Common Air Interface CAI (CAI) of mobile unit (mobile phone or other portable unit) through using mutual signaling of regulation or Handshake Protocol set up.How CAI explain in precise term user and base station carries out communicating by letter of pay(useful) load signal (speech or data) on one group of predetermined frequency, also define mobile unit and base station and be used to set up the control signal that is in contact with one another.
Communicating by letter between a mobile unit and a base station comprises the exchange of signaling and synchrodata or air interface part, and the exchange of actual voice or data message or pay(useful) load part.In the base station, air interface partly goes out of use, and remaining pay(useful) load part passes to MSC through fixed link, and wherein fixed link is generally land line or microwave link.In the time of can approximately handling the calling of 50 whiles in each base station, typical MSC can respond and connect 100 base stations to PSTN, so be connected the sizable capacity of needs between MSC and PSTN.
Compare with PSTN, all subscriber stations are fixed and are connected singly in wired grid in PSTN, and wireless communication system is extremely complicated.At first, as speaking of, this wireless network needs complicated air interface in order to be provided at phone grade (grade) communication under the propagation condition on a large scale between base station and mobile unit.In order to ensure sufficient covering, need configuration to spread all over many base stations in an area, a hundreds of base station sometimes, and each base station must be connected to MSC.Further, this MSC must provide the connection of each mobile subscriber to PSTN at last.This connection need be linked local exchange carrier (LEC) and at least one long-distance or inner exchanging carrier (LXC) simultaneously.
Traditional method has surpassed the capacity of spendable technology to the requirement of radio communication, and this is the most tangible in the MSC design.When a central office telephone exchange can be handled nearly 1,000,000 line users simultaneously, the most perfect available MSC only can handle 100,000-200,000 phone user simultaneously at present.
A, first generation wireless system
First generation wireless system (analog cellular and cordless telephone) is based on and simulates technology.Transfer structure shown in Figure 2 is typical first generation cellular system.Zone A is covered by a plurality of base stations.Communicate by letter with first mobile switching centre (MSC1) in each base station (BS) in the A of zone.Control MSC and base station network are called as a network altogether (to avoid confusion
1The combination of a plurality of networks will be known as global network).In ensuing discussion, the user below hypothesis in the example initially and usually begins under the business MSC in regional A
1Be called as ownership (Home) MSC.
Area B is covered by other a plurality of base stations (BS) of communicating by letter with the 2nd MSC (MSC2) that form second network.MSC2 is called as visitor MSC, expression user roaming enter by the zone outside the regional A of this independent MSC control.Each MSC comprises three databases together with other device: an attaching position register (HLR), a visitor location register (VLR) and an access control center (AcC), they will be described in detail in the back.
MSC1 and MSC2 all are connected to PSTN as described above.Further MSC1 and MSC2 make link be connected through independent, common signal channel.Signaling System 7(SS-7) (SST) is the signaling protocol that is widely used for common channel signalling between interference networks.SS7 is used to connect most of honeycomb MSC of the whole America, and is the key factor that can register automatically in first generation cellular system with automatic roaming.(see Modarressi, A.R., andSkoog, R.A., " An Overview of Signaling System No.7, " Proceedings of theIEEE, Vol.80, No.4pp.590-606, April 1992, here in the lump by reference).
First generation wireless system between base station and mobile unit, provide simulated voice and poor efficiency, low-rate data transmission.Voice data uses the time division multiplexing form of transmitting between a base station and its corresponding M SC of standard to be digitized usually.Between MSC and PSTN, transmit to voice data digitlization always.
Must in World Wide Web, follow the tracks of the mobile subscriber as the global network of concentrating all to cover the private network of a particular locality, miscellaneous service is provided for these users, and between authorized user and possible invador, differentiate.For realizing these tasks, no matter to be authorized mobile unit when to work, it all monitors the strongest control channel that sends from least one base station in its vicinity.As long as only motion (promptly staying in its home network) in a zone of user with regard to the position and the activity of a MSC (ownership MSC) monitoring user, and is switched this user between this regional base station.
Therefore, when this user roams into another zone of other MSC (promptly roaming into visitor network) covering, the global radio network must be registered this user and cancel this user's registration in the ownership district in this visitor district, so that suitably select the route of incoming call to give the user of roaming.Up to the initial stage nineties, also must in each visitor district, manually register their mobile unit in the interregional user's roaming that is covered by different business supplier network operating.Having realized allowing different cellular systems automatically to finish between them jointly when these service suppliers roams.During user's IS-41 procotol standard, this loaded down with trivial details requirement is just exempted.This " interoperability roaming " that is realized by IS-41 allows different business supplier's MSC to go to exchange on demand, provides transparent user to serve necessary user profile at whole network range.
IS-41 relies on " registration automatically " characteristic alleged in the AMPSAdvanced Mobile Phone Service (AMPS).(see Young, W.R. " Advanced Mobile Phone Service:Introduction, Background andObjectives " Bell Systems Technical Joumal, Vol.58, PP.1-14, January 1979, in the lump here by reference).Automatically registration is that a mobile unit is notified a kind of processing of its place with the service MSC that is positioned at.The identifying information (be its mobile ID (MIN) and its Electronic Serial Number (ESN)) of mobile unit by encouraging and send it periodically finished this, and this allows MSC constantly to confirm and upgrade its subscriber's meter.
Referring to Fig. 2, the built-in function that constitutes each unit of first generation wireless system will be described now.A user starts from the regional A that he or she belongs to the district, and is identified in belonging to the access control center (AcC) of MSC1.Attaching position register among the MSC1 (HLR) comprises the service features that contains register information, distribute to the user and the user profile value of record keeping/management information.Travelling in regional A is controlled by MSC1.And when this user was roamed into area B, MSC1 must let go control to MSC2.For this reason, MSC2 sets up the record to this user in its Visited Location Registor (VLR).This record comprises the user profile value and relevant information that is obtained from MSC1 through independent SST link by MSC2.In case the user is suitably kept accounts in the VIR of MSC2, the activity of this user in area B just controlled by MSC2.The effect of switching between the roamer's net that sends between MSC1 and the MSC2 and the information of record keeping are commonly called mobility management information.IS-41 interface on SST link and particularly the SST link provides a communication path, is exchanged between net by its mobile management message.
Mobility management information is different from call control information, although it relates to call control information.Call control information is to determine to transmit the exchange message of useful signal (speech or data) to the physical path of its final destination.Call control information communicates between MSC and wired switching system.
B. second generation wireless system
Compare with first generation wireless system, second-generation system has used digital modulation and advanced call handling capacity.The example of second generation wireless system comprises (GSM) system of the global mobile system of using standard I S-54 of telecommunications industry association (TDMA) and IS-95 (CDMA), the local loop systems of using personal access communication system (PACS) and the system that adheres to digital europe cordless telephone (DECT) standard.
As shown in Figure 3, second generation wireless system has been introduced new network configuration, the needs of MSC when it has reduced call treatment, and can be counted as comprising three essential parts: base station sub-system, network exchange subsystem and public (wired) network.
For example GSM has introduced the notion of inserting one or more base station controllers (BSC) between one or more base station transceivers (BTS) and MSC.Therefore, in GSM, MSC still contains HLR, VLR and AcC function, communicates by letter with other MSC through the SS7 link, and is connected to public (wired) network that contains PSTN, ISDN and/or public database.The structural change of this increase BSC has allowed the standardization of the data-interface between BSC and MSC, therefore allows service supplier to use the MSC and the base station parts of distinct device manufacturer.
All second generation wireless systems all use digital voice coding and digital modulation.In calling was carried out, these systems used the Dedicated Control Channel (common channel signalling) of the air interface that is used for exchanging simultaneously speech and control information between mobile unit, base station and MSC.These systems are also providing special-purpose speech and signaling main line between each MSC between each MSC and public (wired) network.
Different with the first generation wireless system that designs for speech, second-generation system by specialized designs so that paging and for example other data service of fax and high-speed data network access to be provided.The second generation wireless system that strengthens will provide PCS Personal Communications System (PCS) or the personal communication network (PCN) (PCN) that realizes fully eventually, they provide the radio communication that exists to cover everywhere, satisfy the needs that the user inserts the public network of dissimilar communications, and do not need to consider the position of information in public network or user's position.
The notion of PSC/PCN is based on advanced person's intelligent network (AIN), it have comprehensive all move whole accesses with fixed network as target, to offer single " greatly " net and the various accesses of database.In theory, AIN also allows the user to have a single telephone number that uses everywhere in wireless and wired system, (referring to, Ashitey, D.Sheikh, A, and Murth, K.M.S., " Intelligent Personal CommumicationSystem " 43rd IEEE Vehicular Technology Conference, PP696-99,1993, be incorporated herein by reference to).
On characteristic, the network control structure of second generation wireless system distributes more than first generation system, and this is because inference mobile unit and base station sub-system part can be born bigger call treatment load.Towards this trend of distribution control structure more fully MSC in the cancel all wireless system arrangements has been proposed at present.
The invention provides a kind of comprehensive wireless and wired system (IWWS) structure that does not need mobile switching centre (MSC), but it uses existing wired switching equipment and ability effectively, so that comprehensive Wireless/wired service is offered the user." merging " result of public (wired) network portion and wireless communication system part (BTS and BSC) provides the advantage of many economy and technology to service supplier.For example, the IWWS structure allows service supplier to reduce purchasing, reduce maintenance cost, simplifying the comprehensive of equipment of the network equipment.In fact, provide the selection of the influential existing wired ability of wired and service supplier wireless service, and do not rely on the MSC of independent realization, to realize wireless service cheaply.
MSC has not only reduced hardware cost by cancellation, and service supplier combination of wireless and wired requirement that accounts easily, introduce the current a lot of characteristics that in cable service, provide rapidly to wireless service, integrated wireline directory number, and concentrated physical operations and maintenance centre.
On the one hand, of the present invention provide a kind of between radio base station controller and cable convertor through the direct IWWS of switched call control messages of a standard interface (preferably GR-303).This switch is 4 classes or 5 class switches preferably.Mobility management information utilizes SS7 to exchange through the IS-41 interface.
On the other hand, the invention provides a kind of method of between wireless system that is used for the mobile subscriber and cable convertor, transmitting call control message with IWWS, wherein in case calling begins, the mobile identification number of receiving from the mobile subscriber just is delivered to the wireless traffic control point of distributing to an interface directory number (IDN) based on MIN.This IDN is returned to wireless subsystem, and connects between wireless subsystem and wired exchange through a signaling interface, and this interface is GR-303 preferably, but also may be ISUP, PRI, R1 or R2.And cable convertor preferably 4 classes or 5 class switches.
