US 6397069 B1Abstract
In order to be able to control the setting up of telecommunication connections efficiently and reliably in telecommunication subsystems serving as local message transmission loops of telecomunication systems and having network terminations which differ with regard to the transmission channel requirements, a first network termination specifies explicitly, for example in the form of a parameter, the requested transmission channel desired by it in a connection, set-up message of the network termination to the remote station in the telecommunication subsystem.
a) transmitting system messages on system channels in the telecommunication systems; b) providing the telecommunication subsystems with a plurality of subsystem channels for transmitting subsystem messages and the system messages; c) providing the telecommunication subsystems with telecommunication interfaces, which are connected via network termination-specific subsystem channels to second telecommunication interfaces and/or third telecommunication interfaces, which are structured as network terminations, and also via network-specific subsystem channels to the system channels; d) incorporating the telecommunication subsystems into the telecommunication systems via the telecommunication interfaces; e) providing the network termination-specific subsystem channels with signalling channels and user data channels; f) transmitting the messages from and to the second telecommunication interfaces via the signalling channels and/or the user data channels, and transmitting the messages from and to the third telecommunication interfaces via the user data channels; g) transmitting first subsystem messages having first parameters from the second telecommunication interfaces and/or the third telecommunication interfaces to the first telecommunication interfaces, for connection setting up; h) transmitting the first parameters of the first subsystem messages having first parameter values containing contents “SIGNALLING CHANNEL ONLY” from the second telecommunication interfaces to primary telecommunication interfaces of the first telecommunication interfaces; i) connecting the signalling channels to first channels of the network-specific subsystem channels for connecting the signalling channels to the system channels and/or for routing of the signalling channels of the telecommunication subsystem to the telecommunication systems. 2. The method according to claim 1, wherein a number of first channels is limited.
3. The method according to claim 2, wherein as a response t the first subsystem messages having the first parameters and the first parameter values, second subsystem messages having second parameters and second parameter values containing contents “PRIMARY TELECOMMUNICATION INTERFACE BUSY” are transmitted from the primary telecommunication interfaces to the second telecommunication interfaces when the first channels are all busy.
10. The method according to claim 1, wherein the telecommunication subsystem is one of an “IS-54” system or a PDC system.
13. The method according to claim 7, wherein the first subsystem messages are DECT-specific “MAC protocol layer” messages “BEARER_REQUEST”, the first parameters are DECT-specific “MAC protocol layer” parameters “SERVICE TYPE”, the first parameter values having the contents “SIGNALLING CHANNEL ONLY” are DECT-specific “MAC protocol layer” parameter values “Cf-CHANNEL ONLY”, the second subsystem messages are DECT-specific “MAC protocol layer” messages “RELEASE”, the second parameters are DECT-specific “MAC protocol layer” parameters “RELEASE REASON”, the second parameter values having the contents “PRIMARY TELECOMMUNICATION INTERFACE BUSY” are DECT-specific “MAC protocol layer” parameter values “RADIO BASE STATION BUSY”, and the third subsystem messages are DECT-specific “MAC protocol layer” messages “BEARER_CONFIRM”.
3) the message transmission is wire-based over the trunk transmission route, or is carried out wire-free on the basis of various message transmission methods FDMA (Frequency Division Multiple Access), TDMA (Time Division Multiple Access) and/or CDMA (Code Division Muiltiple Access)—for example in accordance with radio standards such as DECT, GSM, WACS or PACS, IS-54, PHS, PDC, etc. [cf. IEEE Commications Magazine, January 1995, pages 50 to 57; D. D. Falconer et al.: “Time Division Multiple Access Methods for Wireless Personal Communications”].
On the basis of this general definition of a message system, the invention relates to a method for controlling the setting up of telecommunication connections in telecommunication subsystems serving as local message transmission loops of telecommnication systems and having network terminations which differ with regard to the transmission channel requirements, in particular “ISDN/PSTN⇄DECT-specific RLL/WLL” systems, in accordance with the preamble of Patent Claim 1.
Using as references the documents “Nachrichtentechnik Elektronik [Telecommunications Electronics], Berlin 45 (1995) Issue 1, pages 21 to 23 and Issue 3, pages 29 and 30” as well as IEE Colloquium 1993, 173; (1993), pages 29/1-29/7; W. Hing, F. Halsall: “Cordless access to the ISDN basic rate service”, and on the basis of a DECT/ISDN Intermediate Systems DIIS according to ETSI publication prETS 300xxx, Version 1.09, Jul. 31, 1996, FIG. 1 shows an “ISDN⇄DECT-specific RLL/WLL” Telecommunication System IDRW-TS (Integrated Services Digital Network⇄Radio in the Local Loop/Wireless in the Local Loop) with an ISDN telecommunication subsystem [cf. document “Nachrichtentechnik Elektronik [Telecommunications Electronics], Berlin 41-43, Parts: 1 to 10, Part 1: (1991) Issue 3, pages 99 to 102; Part 2: (1991) Issue 4, pages 138 to 143; Part 3: (1991) Issue 5, pages 179 to 182 and Issue 6, pages 219 to 220; Part 4: (1991) Issue 6, pages 220 to 222 and (1992) Issue 1, pages 19 to 20; Part 5: (1992) Issue 2, pages 59 to 62 and (1992) Issue 3, pages 99 to 102; Part 6: (1992) Issue 4, pages 150 to 153; Part 7: (1992) Issue 6, pages 238 to 241; Part 8: (1993) Issue 1, pages 29 to 33; Part 9: (1993) Issue 2, pages 95 to 97 and (1993) Issue 3, pages 129 to 135; Part 10: (1993) Issue 4, pages 187 to 190;”] and a DECT-specific RLL/WLL Telecommunication Subsystem RW-TSS.
The DECT/ISDN Intermediate System DIIS and the RLL/WLL telecommunication subsystem RW-TSS are in this case preferably based on a DECT/GAP system DGS [Digital Enhanced (previously: European) Cordless Telecommunication; cf. (1): Nachrichtentechnik Elektronik 42 (1992) January/February No. 1, Berlin, DE; U. Pilger “Struktur des DECT-Standards” [Structure of the DECT standard], pages 23 to 29 in conjunction with the ETSI publication ETS 300175-1 . . . 9, October 1992; (2): Telecom Report 16 (1993), No. 1, J. H. Koch: “Digitaler Komfort f�r schnurlose Telekommunikation—DECT-Standard er�ffnet neue Nutzungsgebiete” [Digital convenience for cordless telecommunication—DECT standard opens up new fields of applications], pages 26 and 27; (3): tec 2/93—Das technische Magazin von Ascom “Wege zur universellen mobilen Telekommunikation” [The technical magazine from Ascom “Means for universal mobile telecommunication”], pages 35 to 42; (4): Philips Telecommunication Review Vol. 49, No. 3, September 1991, R. J. Mulder: “DECT, a universal cordless access system”; (5): WO 93/21719 (FIGS. 1 to 3 with associated description)]. The GAP standard (Generic Access Profile) is a subset of the DECT standard which has the task of ensuring interoperability of the DECT radio interface for telephone applications (cf. ETSI publication prETS 300444, April 1995).
The DECT/ISDN Intermediate system DIIS and the RLL/WLL telecommunication subsystem RW-TSS can alternatively be based on a GSM system (Groupe Sp�ciale Mobile or Global System for Mobile Communication; cf. Inoformatik Spektrum 14 (1991) June, No. 3, Berlin, DE; A. Mann: “Der GSM-Standard—Grundlage f�r digitale europ�ische Mobilfunknetze” [The GSM standard—Basis for digital European mobile radio networks], pages 137 to 152). Instead of this, it is also possible in the context of a hybrid telecommuication system for the ISDN telecommunication subsystem I-TSS to be designed as a GSM system or PSTN system (Public Switched Telecommunication Network).
In the “ISDN⇄DECT-specific RLL/WLL” telecommunication system IDRW-TS according to FIG. 1, a telecommunication subscriber (user) TCU (Tele-Communication User) with terminal TE (Terminal Endpoint; Terminal Equipment), is included in the ISDN world, with the services available in it, for example via a standardized S interface (S-BUS), the DECT/ISDN Intermediate System DIIS, which is designed as a local message transmission loop—is preferably DECT-specific and is contained in the RLL/WLL telecommunication subsystem RW-TSS—(first telecommunication subsystem), a further standardized S interface (S-BUS), a Network Termination NT and a standardized U interface of the ISDN telecommunication subsystem I-TTS (second telecommnication subsystem).
Taking the “ISDN⇄DECT-specific RLL/WLL” telecommunication system IDRW-TS with the RLL/WLL telecommunication subsystem RW-TSS according to FIG. 1 as a departure point, FIG. 2 shows a typical RLL/WLL scenario. The wire-free connection technology RLL/WLL (Radio in the Local Loop/Wireless in the Local Loop) for example including a DECT system is intended to make ISDN/PSTN services available to an ISDN/PSTN subscriber on standard ISDN/PSTN interfaces in the present case. The use of radio channels (for example DECT channels) in classical cable-based telecommunication systems, such as ISDN/PSTN, is becoming increasingly important, particularly against the background of future alternative network operators without their own complete cable network.
It is furthermore possible to employ a radio network termination with “n” analogue a/b connections. A radio network termination RNT-4 with four a/b connections was introduced in the DECT Link system Version 2 (DECT Link V2). The RNT-4 requires a maximum of up to four user information channels (Traffic Channels) simultaneously. In the case of the radio network termination RNT-4, these user information. channels were generally ADPCM-encoded, as in the case of the radio network termination RNT-1. In order, however, to relieve the load on the DECT radio interface, it is possible, in the case of the DECT Link V2, to operate the individual connections for the radio network termination RNT-4 via different radio base stations RBS (for examiple the three radio base stations RBS1 . . . RBS3). In the case illustrated, the radio network termination RNT-4 is connected, for example, to the radio base station RBS1. The setting up of connections is in this case carried out by a Radio Distribution Unit RDU. A base station control device RBC (Radio Base station Controller) is provided between the radio distribution unit RDU and the individual radio base stations. The base station control device RBC is a pure “layer 1” module. It demultiplexes the data of the radio distribution unit and matches them to the interface to the respective radio base station. The radio base station transmits the data via the DECT radio interface to the radio network termination (RNT-4).
These considerations have led to the DECT Link system Version 3 (DECT Link V3). The DECT Link V3 system has, for example, a DECT-specific radio network termination RNTi with ISDN capability for a terrestrially connectable ISDN terminal TE (Terminal Endpoint) and/or a terrestrially connectable ISDN Private Automatic Branch Exchange PABX as well as a data service-supporting, DECT-specific radio network termination RNT-nd with e.g. “n=4” a/b connections for data transmission for terrestrially connectable data terminals. The radio network terminations RNTi, RNT-nd are connected via a DECT radio interface, having a plurality of radio channels, for example to the three radio base stations RBS1 . . . RBS3.
In principle, the number of respective radio network terminations RNTi, RNT-nd and the number of radio base stations RBS1 . . . RBS3 can be freely selected; it will, however, preferably depend on the installation location of the “ISDN/PSTN⇄DECT-specific RLL/WLL” telecommunication system (keyword: network planning).
A further—in the present case unlimited—channel resource is necessary for the routing of the user data channel on the terrestrial side (between radio base station and radio distribution unit).
For the transmission of theme chapels, a connection is set up via the DECT radio interface in the telecommunication subsystem, more precisely the radio base station and the radio network termination, in each case on the MAC protocol layer with a “B field set-up procedure for advanced connections” (cf. ETSI Publication ETS 300175-3, October 1992, Chapter 7.3, in particular is Chapter 7.3.3).
2) the user data channel of the radio network termination RNT-nd with the capacity of 32 kbit/s cannot be distinguished from the Cf channel using the “B field set-up procedure for advanced connections”.
The user data channel of the radio network termination RNTi with the capacity of 32 kbit/s can be distinguished from the Cf channel of the radio network termination RNTi using the transmission path parameter “LCN” (Logical Connection Number).
One suggested solution to the problem is based on the evaluation of the transmission path parameter “LCN” and of the parameter “PMID” (Portable MAC IDentifier) of the MAC message “BEARER_REQUEST” (cf. ETSI Publication ETS 300175-3, October 1992, Chapter 7.3.3.2). Using these parameters, the radio base station would enquire of the radio distribution unit whether the requested channel is a Cf channel.
The radio distribution unit manages the request data and can thus unambiguously identify the requested channel using the parameters “PMID” and “LCN”.
The object on which the invention is based consists in enabling the setting up of telecomunication connections to be controlled efficiently and reliably in telecommunication subsystems serving as local message transmission loops of telecommuication systems and having network terminations which differ with regard to the transmission channel requirements, in particular “ISDN/PSTN⇄DECT-specific RLL/WLL” systems.
As a result, the remote station can—particularly when the channels requested by the network terminations are identical with regard to the transmission capacity—on the one hand distinguish between the network terminations and, on the other hand, accordingly assign the respectively requested channel to the network terminations.
FIG. 3 uses a stimulus state diagram to show how it is possible to control the respective setting up of telecommunication connections efficiently and reliably in telecommunication subsystems serving as local message transmission loops of telecommunication systems and having network terminations which differ with regard to the transmission channel requirements, in particular “ISDN/PSTN⇄DECT-specific RLL/WLL” systems.
The radio network termination RNTi sends to the radio base station RBS2 the connection set-up request after reception of a MAC message “CONNECTION_REQUEST” CRQ (cf. ETSI Publication ETS 300175-3, October 1992, Chapter 8, 8.1, 8.1.1) with a first subsystem message SSM1, corresponding to the MAC message “BEARER_REQUEST” (cf. ETSI Publication ETS 300175-3, October 1992, Chapter 7.3.3.2), via the DECT radio interface. This subsystem message SSM1 contains a first parameter “SERVICE TYPE” having a first parameter value “Cf-CHANNEL ONLY”.
If the radio base station RBS2 cannot make the required channel resource available because all of the first channels are busy, the connection request is rejected in that the radio base station RBS2 transmits a second subsystem message SSM2, corresponding to the MAC message “RELEASE” (cf. ETSI Publication ETS 300175-3, October 1992, Chapter 7.3.3.10) to the radio network termination RNTi. The second subsystem message SSM2 indicates the reason for rejecting the connection by means of a second parameter “RELEASE REASON” contained in the subsystem message SSM2 and having a second parameter value “RADIO BASE STATION BUSY”.
Since the radio base station RBS3 can make the required channel resource available because at least one first channel is free, the connection request is accepted in that the radio base station RBS3 transmits a third subsystem message SSM3, corresponding to the MAC message “BEARER_CONFIRM” (cf. ETSI Publication ETS 300175-3, October 1992, Chapter 7.3.3.3), to the radio network termination RNTi. Still further messages are then transmitted between the radio base station RBS3 and the radio network termination RNTi, until the radio base station RBS3 sends a MAC message “CONNECTION_INDICATE” CIN (cf. ETSI Publication ETS 300175-3, October 1992, Chapter 8, 8.1, 8.1.1) to the radio distribution unit. Afterwards, further messages are once again transmitted between the radio base station RBS3 and the radio network termination RNTi until the radio network termination RNTi sends a MAC message “CONNECTION_CONFIRM” CCF (cf. ETSI Publication ETS 300175-3, October 1992, Chapter 8, 8.1, 8.1.1) to the subscriber station. The invention is not limited to the particular details of the method depicted and other modifications and applications are contemplated. Certain other changes may be made in the above described method without departing from the true spirit and scope of the invention herein involved. It is intended, therefore, that the subject matter in the above depiction shall be interpreted as illustrative and not in a limiting sense.
