A method and system in a communications network for providing a communication service between client interfaces and / or for transmitting various types of communications to a client interface.

FIELD OF THE INVENTION The present invention relates generally to communication. The invention relates generally to communication. More particularly, the invention relates to a method according to the preamble of claim 1 and a system according to the preamble of claim 8 for providing a communication service between client interfaces and / or for transmitting various types of communication to a client interface.

It is known that different types of communication, such as voice, data, multimedia and video / TV communication, require different communication speeds to enable trouble-free communication. In narrowband connections, without delay and without compression of the signal to be transmitted, only voice and data communication are easily provided if the moving: *: signal does not contain a moving image. Thus, in order to allow the transmission of all different types of signals, the access interface or network of the client interface to the communication network must be sufficiently wide-banded. In the future, the connection or network '*': for simplicity, will be referred to as the connection attribute. In this case, it is preferred that the connection rate, * ·: is at least 64 kbps. 1 In this specification of the invention, "client interface" generally means a physical terminal, such as a telephone or 'communicating with a communication network, wired or wirelessly; * 'Workstation. A client interface, which in itself includes one or more wired or wireless interfaces, is also intended to include a wide area network, e.g.

i »» - LAN (Local Area Network) and Wide Area WAN (Wide Area Net-T: 30 work). Ethernet, token ring, ARCNET and up to thousands of users, *: Serving FDDI (Fiber Distributed Data Interface), 2 113316 - Wireless Local Area Network (WLAN) based on IEEE 802.11 - Open Internet and TCP / IP closed Intranet, which can be wired or wireless.

5 A client interface is also meant a logical interface with an interface or communication network for transmitting and receiving signals from a client interface over a communication network.

A communication network, which may be public or non-public, is understood to mean both a fixed data traffic or data communication network to which a client interface is connected via a wired connection, and The communications network may thus itself be any commercial or non-commercial network elements owned and / or owned by a network operator or service operator such as a telepalve-15 operator and / or a mobile service operator, such as switches, gateways, base station systems, various registers and databases. a communications and / or communication network consisting of circuit, packet switched and / or router / switch connections.

20

Information is transferred from the communications network to the client interface and vice versa over the wired ':' or wireless interface. To implement wired and / or wireless connection ·. * ·: Uses connection technology such as WEB, PLMN, PSTN, ISDN, cable TV and the like.

25 ♦ · · "· · One of the preferred fixed connectivity solutions is widespread xDSL (Digital Subscriber Line) (DSL) technology, including ADSL (Asym- metric DSL), RADSL (Rate- Adaptive DSL from Westwell), CDSL (Consumer DSL ,, / from Rockwell), HDSL (High bit-rate DSL), SDSL (Symmeric DSL), UDSL (Unidirec-: 30 tional DSL), VDSL (Very High DSL). Other fixed connections between the communication network and the • • i interface can also be used.

113316 PLMN (Public Land Mobile Network) information is transmitted from the client interface preferably by applying xDM (Division Multiplexing), which may be Code Division Multiplexing (CDM), Time Division Multiplexing (TDM), and / or FDM-channeling. (Frequency Division Multiplexing).

Since the aforementioned general structures, functions, connections and signaling of communication networks are obvious to those skilled in the art and are not essential to the present invention, they will not be further described in the context of this specification. It is noted, however, that in data transmission networks such as the network using TCP / IP protocol, data information is typically transmitted based on IP addresses and packaged in relatively small units, i. packets, i.e., a typical communication network, is a packet data network. In this case, the server providing the service communicates with the access server (s) in question. a data network which in turn is connected to a communication network, wherein the data transmission path from the server providing the service to the client interface or the network may be established over the server interface to the communication network and from the communication network over the client interface to the client interface or network.

Since it is not essential to the present invention to establish a client interface:: · · * over an interface to a communication network, it should be noted that the connection establishment may be::: 20 or the client interface is connected to a communication network. The client interface may thus be a fixed network interface, whereby there is a broadband connection between the fixed connection and the communication network, preferably an xDSL connection, or a mobile network interface such as GPRS (General Packet Radio Service) or a third-generation 3G *. ... · an interface such as UMTS (Universal Mobile Telecommunications Service) or 25 WCDMA (Wideband Code-Division Multiple Access), whereby there is a broadband connection, preferably an xDMA connection, between the mobile and the communication network; · * (DMA, Division Multiple Access).

, .. · As stated above, the client interface may be a single terminal such as a telephone or: 30 workstation, the client interface may comprise a wide area network such as LAN, WLAN, WAN,

Bluetooth, RF (Radio Frequency), Intranet, Internet, or other closed or non-closed 4113316 communication network, followed by a network server, router, switch, router / switch combination, or so-called. hub or similar device for multiple wired or wireless terminals. When the client interface is a single terminal or area network, the connection between the client interface and the communication network may be wired or wireless. When the client interface 5 is an area network, the terminals in the area network may be wired and / or wireless terminals.

The term SIP (Session Initiation Protocol) is used in this description of the invention, since SIP is described in detail in IETF RFC 2543, SIP-10, SIP signaling or control is not described in further detail.

The term Proxy is also used in this description of the invention. Proxy generally refers to a server that acts as a mediator between a client interface or client terminal and a network that uses the IP protocol, such as the Internet. QoS (Quality of Service) 15 features measure transmission rate, error rates, and other features, and to some extent, ensure quality of transmission. QoS is primarily concerned with continuous broadband video and multimedia communications, the content of which is difficult to transmit using standard 'Best Effort' protocols, typically associated with Internet communications.

A state of the art is represented by WO 02/09358, in which the method:, ·, 'allocates a certain amount of frequency band to subscriptions and dynamically changes it based on the available frequency band and the bandwidth required by the subscriptions.

• ·

The method utilizes a QoS class data structure and a WRR (Weighted Round Robin) method to optimally allocate the available frequency band 25 to the subscriptions that need it.

'·; · * Still in this description of the invention, DSLAM (Digital Subscriber

Line Access Multiplexer). DSLAM refers to a device in a network operator's exchange that receives interface signals from client-30 subscriber lines from multiple lines, e.g., xDSL lines, and sends them to backbone lines. The backbone is a larger transmission line that carries data and is collected from smaller lines associated with 5,113,316. backbone line. Locally, a backbone is a line or group of lines whose area network, such as a LAN, connects to a larger area network, such as a WAN, or which effectively bridges distances within the area network. Internet backbone or other larger network backbone is a set of buses connected by local or 5 regional networks to long distance connections. The access points are known as nodes or exchanges in a message-to-network.

In traditional data communication between a client interface and a communications network, a fixed bandwidth connection is used. The disadvantage here is that sometimes 10 has unnecessary bandwidth and sometimes the available bandwidth is insufficient to provide the desired data transmission or service. Such communication or data transfer techniques include: fixed-speed fixed xDSL connections or optional connections with sufficient bandwidth between a fixed connection and a communication network. Such fixed-bandwidth communication and data communication technology is also used in UMTS, a 3G radio system based on ETSI standards developed from the GSM system, for the transmission of text, voice, images and multimedia data over the air at speeds up to 2 Mbps. .

The prior art WCDMA Broadband Broadband System is a 3G Broadband System compliant with ITU standards. WCDMA is generally based on CDMA technology and applies: · variable bandwidth that is optimized based on the type of data being transmitted.

'· WCDMA is a third generation (3G) wireless communication technology and its purpose is to provide higher data rates over the wireless interface and thus more efficiently support different types of communication. WCDMA is a modulation and multi-access ankle, based on a known spread Spectrum model. '' Spread Spectrum '«t1 * ;;; is a form of wireless communication in which the frequency of the transmitted signal is changed • • • 1 *! 1, resulting in a significantly higher bandwidth than if the frequency of the signal were not changed. However, there are problems with WCDMA technology with conventional wireless communication: the technology is designed to change the bandwidth of only one data type V · 30 at a time; a constant frequency signal is exposed. '· · For strong interference. This occurs when the second signal is transmitted at the same or very close frequency with the desired signal frequency. High interference may be unintentional, as in radio amateur communications, or intentional, as in wartime; and the constant frequency signal is easy to intercept and therefore not well suited for applications where the information must remain confidential between the sender 5 and the receiver. Another disadvantage of WCDMA is that it can only transmit one type of data at a time over an access network.

It is a general object of the present invention to eliminate or at least substantially reduce the weaknesses and disadvantages associated with conventional service delivery and to provide an improved method and system for video / TV communication of various services, particularly preferably differentiated communication services and / or data communications. communication or data transmission and / or Internet protocol application using IP protocol, for managing and / or improving the communication network over a tracked router or switch means between the client interfaces or the server providing the service and the 15 client interfaces.

One particular object of the invention is to provide a flexible bandwidth between a client interface and a communications network, i. · an interface with variable bandwidth or data transmission or communication needs. Such a flexible bandwidth connection according to the invention will hereinafter be referred to as a dynamically changing bandwidth interface. Dynamically changing li- *: * '! thus, the bandwidth of the pack changes to different communication needs and generates and guarantees' | • Sufficient data transfer capacity and speed in different communication and data transfer modes. The invention thus enables, for example, simultaneous telephony with, for example, TV / Video communication or other multimedia communications and / or 'Best Effort' type * * · ...: data transmission such as IP communication using IP protocol.

10

In addition to conveying different types of communication, the invention also allows only one type of communication, e.g., 'Best Effort' type communication, TV / Video or similar multimedia communication or SIP-controlled voice communication, communication of at least two different types of traffic of that type. / or data transmission over a client interface interface having a dynamically changing bandwidth backbone which, for each type of traffic, is divided into subbands having a dynamic bandwidth relative to each other depending on the data transfer or relay need. Thus, according to the invention, it is advantageous for traffic types of one type of communication to be prioritized over different priorities with respect to each other, and: the bandwidths of the subband of the traffic types may occupy the entire maximum bandwidth or; : dynamically change over the entire bandwidth.

According to one aspect of the invention, the object is to enable the transmission bandwidth to be increased and narrowed depending on the particular communication need. According to another aspect of the invention, the object is to prioritize different types of communication types or one type of communication type according to the communication rules to optimize the bandwidth required for each type of communication type or type of communication type.

; '; These general and aspect objects of the invention have been achieved by the aforementioned method and system, the features of which are defined in the appended claims. In this case, the general characteristics of the method according to the invention are set forth in the characterizing part of the attached independent claim 1, and the general characteristics of the communication rigid system according to the invention are given in the characterizing part of the accompanying independent claim 8.

According to a preferred embodiment of the invention, the different communication types transmitted by the communication band are prioritized with respect to each other, whereby each communication type is provided with its own communication sub-band of the communication band. There are at least two types of communication types to be transmitted, as noted above. For the implementation of the prioritization 10 according to the invention, e.g., for three different types of communication types, it is preferred that the lowest priority be given to "best effort" communication, which is typically data transmission, preferably TCP / IP, to medium priority multimedia communication. preferably TV / video communication, and that the highest priority is given to communication, which is preferably SIP-controlled communication and / or voice traffic. Naturally, a larger number of different types of communication with different priority can also be used.

In connection with the invention, it should be noted that the prioritization can also be implemented within a single communication type for different types of traffic of the communication type or for optional services. In this case, for each type of traffic or optional service; ; A dedicated traffic band or * service specific subband is reserved for the traffic band or subband bandwidth.

* · ·: Due to the limited bandwidth 25 of the client interface to the communication network and the preset basic and maximum bandwidths, jj * must be prepared for the simultaneous use of communication types and / or traffic subbands. the agreed maximum bandwidth or size: · · · exceeded the bandwidth.

; ·. According to a preferred embodiment of the invention, this problem of preventing possible overpass of total bandwidth may be solved by reducing the sum of the lower priority communications type or traffic subband to the upper * * * · 9 113316 priority communication type or subspace or bandwidth remains below the maximum bandwidth of the total communication bandwidth of the connection.

According to another preferred embodiment of the invention, this problem of preventing the total bandwidth from being exceeded can be solved by reducing the sub-bandwidth of each type of communication or traffic type so that the sum of the sub-bandwidths is below the maximum bandwidth of the total communication bandwidth. Here, preferably, the sub-bandwidths of all communication types or traffic types are reduced proportionally by the same amount so that the sum of the sub-bandwidths is less than the maximum bandwidth of the total communication bandwidth of the connection. It is particularly advantageous that the sub-bandwidths of all communication types or types of traffic are reduced by the same percentage so that the sum of the sub-bandwidths is below said maximum bandwidth.

Among the essential advantages of the invention, it can be mentioned that the interface, and in particular the total bandwidth of its interface, and thereby the connection speed, is j '.'; - QoS- tracked by the client, i.e. the client interface to the communication network; 20 routers through a request to be signaled to the QoS router management tool or «; - automatically from the communications network: **: dynamically adjustable to control the total bandwidth of the interface, and * ·: that the interface allows all different types of communication and data communication, such as secure SIP-controlled voice communication, 25 TV, and video service brokerage, as well as traditional Internet communication over or without an operator-driven firewall. firewall protection.

According to the invention, a dynamically changing connection between a communication network client interface can be activated from either a connection user interface, i.e. a connection, a user interface, or a connection user interface, i.e. a connection user. : Joining an independent third-party client interface.

For other details and advantages of the invention, reference is made to the appended claims.

The invention will now be described with reference to one or more preferred embodiments and embodiments thereof, with reference to the accompanying drawings, in which Figure 1 illustrates generally a transmission system according to the invention in a communication network,

Figure 2 illustrates the distribution of communication or data traffic in a bandwidth dynamically changing access bandwidth to subbands according to an example of a data transfer protocol,

FIG. 3 illustrates one signaling example where it is desired to change the bandwidth by the amount corresponding to the request, either by narrowing the bandwidth of the client interface, widening the bandwidth of the client, or releasing enough lower priority bandwidth to receive another data type or the subscriber interface, server, or to another subscriber connection or by a third party, and Figure 4 illustrates a second signalointiesimerkkiä, wherein the bandwidth request is to be changed, either by reducing the amount corresponding to the client interface kaistanleveyt-; ·. by widening the bandwidth of the client interface, or by releasing enough lower bandwidth.

; '': Referring to Fig. 1, a communication system 200 provided in a communication network 200 in accordance with the present invention which enables enhanced communications to be implemented; between the client interfaces 100 of the communication network 200 and the server 301, 302, 401 providing the service of forwarding differently prioritized types of communication types, the client interface 100 includes at least one data network 300, 400 which is preferably a TCP / IP protocol. an applied data network, such as the Internet, and to which data network the server providing the service is connected; 301, 302, 401, and which data network is connected to a communication network 200 for transmitting services * i 11 113316. the server over the data network and communication network and the client interface 100 and the communication network interface, i.e. the access connection 500, between the communication network and the communication network. Thereby, for transmission of different types of communication from the communication network 200 through a router and / or switch means, preferably a QoS router 202, to the client interface 100 comprises a data transmission band of variable bandwidth. Since the type of data network 300, 400, or communication network is not essential to the present invention, it is briefly stated that information packetization in the data network for implementing data transfer can be accomplished in other ways than using the TCP / IP protocol. However, due to its wide spread and open interfaces, the TCP / IP network is the preferred option for 'Best 10 Effort' communication. It should also be noted that the communication network may be a fixed or mobile network, however, it is preferable that the interface of the client interface 500 to the communication network 200 can be traced to broadband.

Referring to FIG. over router 202, controlling the total bandwidth and / or subband bandwidth of the communication band, *; ', 20 QoS routers 202.

The realization of the communication link between the QoS router 202 and its management device 204, which is: * ·. · Typically a connectionless communication link, is in itself an intermediate in the art: "*: substantially problem-free for the skilled person.

25 - If both the QoS router 202 and its management device 204 are in the communication network, the '| * utilize network protocols known as telecommunications for network communication between the QoS router 202 and its management means 204 * · * t>. ', such as xUP (User Part) above the third layer of a seven-layer OSI model. and xAP (Application Part) Web. 30 co-protocols such as TUP (Telephony User Part), ISUP (ISDN User Part),. ,: MAP (Mobile Application Part), TCAP (Transaction Capabilities Application Part), i · 12 113316 IN AP (Intelligent Network Application Part), OMAP (Operation and Maintenance Application Part). The system according to the invention is then a system distributed in one communication network.

If the QoS router 202 arranged in the communication network 200 is in communication 5 with an access server such as an IP protocol data network, such as the Internet, network communication elements known from telecommunication elements may be used to establish the first communication connection between the QoS router 202 and the access server (not shown). UP or AP network protocols, and use, for example, the TCP / IP protocol to implement a second communication link between the management means 204 and the access server 10 (not shown). The system of the invention is then a distributed system of at least two communication networks, of which at least one of the telecommunication networks is a data network, such as the Internet.

The QoS router 202 and its management means 204 may also be integrated into one network element 200 of the communication network 15. In this case, there is no need for a specific standard network protocol solution to implement communication between functions, but the necessary communication can be implemented by internal control of the network element in question. The system according to the invention is then an integrated network element in a communication network.

: 20. A data bandwidth which is dynamically changing in bandwidth is reserved for kek-. .. | according to the invention, for different types of communication or communication types having different priority and / or different priority for one communication type; '': Sub-lanes for different types of traffic. In this case, • · # 25 - “Best Effort” traffic such as Internet traffic, multimedia communications such as #; : * TV / video communication, and eg IP or SIP controlled calls can be forwarded in each of their own communication type subbands, - each of the one communication type subbands can transmit e.g. 'Best Effort' traffic based on IP protocol , such as security, alarm,? t 30 spatial information, tracking services, etc., each with a different prio · ·, ·,: rity, a single type of communication can of course be other than the “Best Ef” · · · »t 13 113316 forf traffic band such as eg TV / Video / Multimedia traffic band, whereby different types of communication, such as news or sports broadcast channel (s), video films, TV channels, are assigned different priorities, - different types of traffic of one type of communication which can be prioritized over others, and - at least one of the two types of traffic to be transmitted is divided into at least two traffic types of different priority, whereby the traffic types are transmitted within the subband of the traffic type of the respective traffic type.

In order to allow different types of communication types to be transmitted to the client interface 100 for different usage situations and for different communication needs, different types of communication types are prioritized over several, i.e. at least two types of data transmission and data transmission rules apply in the data transfer according to the present invention. The most common types of data transmission are: a) "best effort" data transmission, such as internet data transmission or other IP service received from a data network using TCP / IP protocols such as security, alarm, monitoring services, etc. ,, *; . B) multimedia communications such as typically QoS-supported TV / video communications: and c) SEP-controlled communications, preferably SlP-controlled calls, usually requiring high quality, i.e. QoS-supported communications. data transfer.

In this case, according to the invention, a) class "best efforf" communication has the lowest priority, b) class multimedia communication has a medium priority, and c) class SIP: · controlled communication has the highest priority.

..: In general, the following is stated in the Code.

'. - The Code ensures that the total data transfer or communication capacity used is not

30 exceeds the connection's total physical bandwidth of 500. Eg ADSL

• ·,. the connection can have five (5) call connections, three (3) * »• · 14 113316 TV / video connections (2MBps) and 'best effort' traffic at the same time. Management of the system of the invention allows for an increase in the best effort traffic bandwidth if one or more sub-priority communication subbands, such as a TV / Video channel and / or a call link, are removed from the connection bandwidth. Similarly, the 5 best efforts traffic will be automatically reduced, preferably automatically, if one or more new sub-priority communication sub-bands, such as TV / Video channels and / or call connection, are opened.

The code controls the bandwidth and quality characteristics of the connection 100 of the client interface 100, for example, through the settings of the QoS router 202. In this case, the QoS-10 router is thus required to have at least 500 total bandwidth management capabilities, and in addition quality management features.

- Mutual priorities are defined for logical channels based on the priority mechanisms provided by the protocol used, for example Internet Protocol (IP) Quality of Service (QoS) classes. The classification may be, for example, high-priority SIP-15 directed call communication traffic, medium-priority TV / video or similar Multimedia traffic, and lowest priority "Best Effort" traffic. In addition, at least one intermediate priority traffic may be transmitted over the QoS router 202.

According to an embodiment of the invention, the client interface 100 is provided with the desired · ·. 20 optional baseband and maximum bandwidths that determine the connection 500. total bandwidth of the data bandwidth. As the communication bandwidth used in the client interface within the total bandwidth of the client interface 100 approaches the maximum bandwidth, the bandwidth of the higher priority communication type decreases the bandwidth of the lower priority, so that the sum of the subbands bandwidths remains at the full bandwidth.

Alternatively, each subband bandwidth of 100 communication types to be transmitted to the client interface is reduced so that the sum of the subband bandwidths remains within said total bandwidth. In this case, subband bandwidths can be achieved. 30, such that all communication types I · f, ·,; the bandwidths of the subbands are reduced proportionally by the same amount, i.e. preferably equal to * * »* · 15 113316 man. In this case, the sum of the subband bandwidths remains within the agreed total bandwidth and below the maximum bandwidth.

Referring to Fig. 2, which illustrates the distribution of information to be transmitted on a communication path according to an example of a communication policy in different situations. It is to be emphasized that Figure 2 illustrates only some of the communication situations, which are numerous, depending on the particular communication situation and need.

Steps in Figure 2: 10 1. The client interface is in a contracted state with a base bandwidth bandwidth of the best-effort sub-bandwidth.

2. The user adds top-priority service over the baseband, i.e.. For SIP-controlled call, a subband of the highest priority communication type. The sum of baseband and bandwidth increments is still less than the agreed maximum 15 bandwidths of the client interface 100.

3. The user closes the highest priority service, thereby restoring the original "best effort" bandwidth 4. The user orders the lowest priority bandwidth, i.

9. The user opens a second intermediate priority connection, thereby limiting the subband bandwidth of the lowest priority-5 communication type.

10. The user opens a third intermediate priority connection, whereupon the entire physical bearer bandwidth becomes available to subbands of the prioritized bearer types. In this case, the traffic service of the communication type with the lowest priority class is suspended.

10 11. The user opens the highest priority service. The sub-band of the lowest communication type is no longer left in the previous step 10, so by limiting this sub-priority sub-band, no further bandwidth can be found by trimming it. Hereby, the subbands of the communication type of the highest priority of the lower priority are uniformly limited, preferably relatively the same, i.e. with the same percentage.

15 12. Returning to step 10 13. Returning to step 9, whereby the low-priority communication type again has the data bandwidth.

As shown in Figure 3; in step 1, a connection is established between the user subscriber line 100 and the service / service 301, 302, 401, which is the original connection of step 2, the bandwidth of which is only the baseband supporting the best effort service. When there is a need to change the bandwidth in the user subscriber interface to enable either another server / service or another communication type, e.g. to increase bandwidth, or disable the "best-effort" service and another service of higher priority, i. to reduce bandwidth, in step 3, a bandwidth change request is routed to the management means 204 of the QoS router 10. This change request can be sent according to the invention - from the user's own subscriber interface 100 to step 3a. from the service / server in step 3b. or - by a third party or second interface 110 in step 3c. in accordance with.

Then, in accordance with step 4, the QoS router management means 204 determines the present case. the possibility of changing the bandwidth corresponding to the request. The result according to this statement is taken to step 5 for processing the bandwidth change condition. ... Then, ♦ I · 7 • · [· · · t 20 - if co. the requested bandwidth is not available, send QoS router shreds, ·,, 1, Tape 204 to the sender of the bandwidth change request, e.g. requested • · · • · · ,, ..: bandwidth is "X" bandwidth is available " Y ”followed by bandwidth- • 1. 1. The requesting or requesting change of bandwidth may adapt the bandwidth change request to the available bandwidth 'Y'. After a new change request, · · · 25 signaling proceeds again to step 4 in the relay system; · · - if the bandwidth requested by the bandwidth change request is available, the switching bandwidth ,, ',; change.

To change the bandwidth, the QoS router management means 204 controls, in step 7, the 30 QoS router 202 to change the bandwidth of the client interface 100 on the one hand. . on the other hand, the settings on the QoS router 202 to match the changed <1 · 20 1 13316 bandwidth. Thereafter, step 7a. accordingly, the QoS router 202 sends a confirmation to the QoS router management device 204 that the settings have been successful. When the bandwidth of the client interface 100 is changed and the success of the configuration change of the QoS router 202 is signaled to the QoS router management tool 204, according to step 8, the QoS routers-5 manager 204 transmits information about the changed client interface bandwidth to billing 205. a connection modified between the services 301, 302, 401 according to step 9 is established whose billing is based on the modified bandwidth.

Referring to Fig. 4, reference is made to Fig. 1. FIG. 4 illustrates another signaling example where it is desired to change the bandwidth by the amount corresponding to the request, either by narrowing the bandwidth of the client interface, widening the bandwidth of the client interface or releasing enough lower priority bandwidth to receive another the subscriber connection, server, or from another subscriber connection or by a third party. As can be seen in FIG. 4, the transmission system of FIG. 4 is substantially similar in configuration and in internal and external interfaces and interfaces to communication network 200 as shown in FIG. 3; * t, but differs from the example of Fig. 3 in signaling the transmission system · ·, 20.

* »* · .. As shown in Figure 4; in step 1. a non-silent connection is established between the user subscriber line 100 and the service / server 301, 302, 401 over the communication network 200; An initial connection according to step 2, with a bandwidth only the base bandwidth that supports the "best effort" service. When there is a need to change the bandwidth in the user • subscriber line; the latitude to take either another server / service or another type of data transfer e.g.

= «♦» in addition to the best efforf' service, ie. to increase bandwidth, or to disable the "best - ,,,,: efforf" service and another service with a higher priority, ie. to reduce bandwidth, in step 3, a bandwidth change request is routed to the QoS router * * * .30 management tool 204. This change request I »« •. may be transmitted according to the invention from »» 21 113316 to the user's own subscriber interface 100 in step 3a. from the service / server in step 3b. or - by a third party or second interface 110 in step 3c. in accordance with.

Subsequently, according to step 4, the QoS router management tool 204 examines, by one or two step condition processing, whether the bandwidth change corresponding to the request is possible. Then in the first step 4a. performing a first query to determine if the bandwidth corresponding to the change request is available.

If the bandwidth corresponding to the change request is vacant, the QoS router 204 can skip the condition queries and proceed to signaling step 6, where the bandwidth of the client interface 10 is changed. the requested bandwidth is not available, proceeding to the second stage of condition handling, where a second query is performed: can sufficient bandwidth of the lower priority 100 of the subscriber interface be released to allow for bandwidth change? If the bandwidth cannot be directly released in response to the change request, the QoS router management means 204 sends a request to the sender of the bandwidth change request, e.g., the requested bandwidth is "X" the bandwidth is available to "Y", and the bandwidth needing or requesting the change request bandwidth 'Y', which results in signaling in the relay system as described above through step 4a to step 6. Alternatively, if the band of change request, ·, 1 is not directly available or cannot be directly released according to the request for change , the bandwidths of the lower or lower priorities may be reduced by the same proportional or physical size to allow a bandwidth change request, which results in signaling in the relay system as described in step 25 above. 4a to step 6 and substantially all the desired services to the client interface 100 are enabled.

'···' In step 6, a change in the bandwidth of the client interface is performed. In this case, the QoS router management means 204 in step 7 directs the QoS router 202 to change the bandwidth of the client interface 100 to match the change request and the settings; '·'; 30 on the QoS router 202 to match the changed bandwidth.

After this step 7a. accordingly, the QoS router 202 sends a confirmation to the QoS router management tool 202 that the settings have been successful. When the bandwidth of the client interface 100 is changed and the successful change of the settings of the QoS router 202 is signaled to the QoS router management means 204, the QoS router management means 204 sends information about the changed client interface bandwidth 30 to billing 205. A connection modified between step 401 is established according to step 9 and billed based on the modified bandwidth.

The invention has been described above by way of example only, by way of example of some of its preferred embodiments. However, this is not intended to limit the invention to such individual embodiments or examples but, as will be apparent to those skilled in the art, many equivalents and / or alternative solutions and variations are possible within the scope of the inventive idea and the appended claims.
