Definitions
- the present invention relates to a method and a system for managing communication traffic.
- the invention deals with the handling of call requests from users being connected to an access network.
- Telecommunication end-users are typically connected to an access network (AN) for communicating with other end- users or service providers.
- the access network is thus capable of routing calls from the end-users within the access network as well as to other networks, such as a public telephony- network (PSTN) and the Internet, for connecting the end-users with other users or service providers .
- PSTN public telephony- network
- the end-users are thereby able to make a variety of different calls, such as voice calls, video calls, web surfing and media streaming.
- the end-users may be equipped with one or more terminals, such as telephone sets, mobile phones, PCs, TVs, with some kind of communication unit which is connected to the access network.
- the connection may be either fixed or wireless . In the following text, any ' end-user and/or terminal will be referred to simply as "user" .
- Fig. 1 is a schematic view of an exemplary prior art telecommunication system including an access network 100. having a plurality of users 102 connected thereto.
- the access network 100 is connected to a service node 104-, acting as a gateway to a PSTN 106, via a standardised communication interface 108.
- the service node 104 may be a local exchange or the like.
- the PSTN 106 comprises further service nodes 110, 112, acting as gateways to other networks 114, 116, e.g., private networks, the Internet, Local Area Networks (LANs) etc .
- LANs Local Area Networks
- the European Telecommunications Standard Institute has defined standards relating to interfaces between different telecommunication networks, such as the interface 108 between the access network 100 and the service node 104.
- Such interface standards specifies a communication protocol comprising predefined messages and data fields, such as address fields .
- One such standard used between access networks and public networks is the V5.2 standard (EN 300 347-1), which is used in concentrating interfaces having a limited number of channels, being fewer than the number of users 102 connected to the access network 100. The V5.2 interface may therefore become congested with calls during peak hours .
- the V5.2 interface was originally designed for ordinary voice calls. However, there has been a shift towards data traffic in recent years where many users accesses the Internet via the V5.2 interface and the PSTN. Data traffic, e.g., over the Internet, is different from ordinary voice traffic since actual transmissions of data are relatively short-lived and bursty, although the connection is usually established during a relatively long time. For example, when a homepage has been downloaded to a PC or a mobile phone, the user wants to study the homepage before the next action is taken. This behaviour will cause conventional traffic models based on voice calls, which where used for dimensioning the V5.2 interface, to be less valid.
- a telecommunication system is disclosed addressing this problem.
- a user being connected to an Access Network (AN)
- AN Access Network
- LE Local Exchange
- An Internet connection is then routed from the TE to an access server (R-AS) in the AN, which is directly connected to an Internet Service Provider (ISP) via a dedicated connection interface which is more suitable for long time data connections than the V5.2 interface.
- R-AS access server
- ISP Internet Service Provider
- a function is provided in the AN and the LE enabling long time connections between a user and the Internet to take place via the access device over the separate interface, rather than over the V5.2 interface between the AN and the LE .
- the LE detects an Internet call request from a TE, the LE sends a BCC (ALLOCATION) message back to the AN for setting up a connection between the TE and the R-AS.
- BCC ALLOCATION
- This object and others are achieved by providing a method and a system for setting up a connection between a user connected to an access network and an access resource, also connected to the access network, using the standardised V5.2 identity field for uniquely identifying the access resource.
- V5.2 identity field which is an existing already defined protocol element in the V5.2 interface standard, for uniquely identifying the access resource.
- the need for introducing a new address field is thereby eliminated. It is possible to use the existing V5.2 identity field since there are typically a number of free address identities available which are not used for the links of the V5.2 interface. In this way, new access resources can be established and identified with a minimum impact on the V5.2 interface standard .
- Fig. 1 is a schematic view of an exemplary telecommunication system according to prior art .
- Fig. 2 is a schematic view of a telecommunication system according to the invention.
- Fig. 3 is a signalling scheme illustrating different steps carried out in the system shown in Fig. 2 when setting up a connection between a user and an access resource.
- a telecommunication network comprising a plurality of users 202 being connected to an access network 200.
- the access network 200 is further connected to a service node 204, acting as a gateway to a public telephony network (PSTN) 206, via a V5.2 interface 208 comprising a limited number of communication links 208a.
- PSTN public telephony network
- the V5.2 standard defines an 8-bit address field in signalling messages, whereby it is possible to uniquely identify 256 different addresses.
- a typical V5.2 interface 208 comprises a much lower number of links or channels 208a, e.g. 16 links, each capable of carrying 2048 kbit/s.
- links or channels 208a e.g. 16 links, each capable of carrying 2048 kbit/s.
- free addresses or link identities which are never used in the V5.2 interface 208.
- these free addresses are used for addressing other functions and resources than those of the V5.2 interface 208, which will be explained later.
- the access network 200 is also connected to a plurality of access resources 212, of which three are shown, 212a-c.
- the term "access resource” is used in this context to generally denote a device, server or node providing access to and communication with at least one specific service provider or dedicated network.
- the access resource 212a is connected to an Internet service provider 214 for communication over the Internet 216.
- the 210 denotes a collection of various interfaces or links 210a from the access network 200 towards the access resources 212, each interface or link 210a preferably using a communication protocol suitable for the characteristics of the service being provided.
- the interfaces or links 210a towards the access resources 212 are separate from the V5.2 interface 208 towards the service node 204.
- the access resources 212 may be physically implemented in any of: the access network 200, each respective service provider, and separate nodes located therebetween .
- the request is forwarded by the access network 200 to the service node 204.
- the request includes an indication of the corresponding access resource 212, which is detected by the service node 204, e.g., by reading a B-number in the request.
- the service node 204 orders the access network 200 in an allocation message to set up a traffic connection directly between a port of the user 202 and the identified access resource 212 over the corresponding interface 210a. In this way, the traffic connection will not take place over the limited V5.2 interface 208. Only a control signalling connection may be maintained over the V5.2 interface 208 during the traffic connection, using a control channel shared with other users .
- the existing V5.2 identity field is used for uniquely identifying the access resource 212a. This is possible, since there are typically a number of free address identities available which are not used for the links of the V5.2 interface 208, as mentioned above.
- logic in the service node 204 determines from the received connection request that a connection should be established between the user 202 and the access resource 212a.
- An ALLOCATION message is then transmitted, comprising a V5.2 identity field uniquely identifying the access resource 212a, from the service node 204 to the access network 200.
- the V5.2 identity field is an existing protocol element in the V5.2 interface standard.
- the access network 200 sets up a connection between a user port of the user 202 and the access resource 212a.
- the access network 200 sets up a connection between a user port of the user 202 and the access resource 212a.
- an exemplary signalling scheme comprising different signalling steps carried out over the V5.2 interface between the access network 200 and the service node 204 when setting up a traffic connection between a user 202 and the Internet service provider 214 via the access resource 212a.
- standard messages for setting up a PSTN connection are used.
- ISDN Integrated Services Digital Network
- the messages transmitted will then be other corresponding messages, such as a SETUP message instead of an ESTABLISH message, etc.
- the access network 200 replies with an ALLOCATION COMPLETE message 306, and the service node 204 in turn returns an ESTABLISH ACKNOWLEDGE message 308.
- the user 202 now gets a dial tone and can send a connection request, as indicated with the arrow 310, over the allocated connection link, using a B- number or the like indicating that a data connection is to be set up to the Internet service provider 214.
- logic in the service node 204 determines that a traffic connection is to be set up between the user port of the user 202 and the access resource 212a, based on the received B-number.
- the access network 200 returns an ALLOCATION COMPLETE message 314 to the service node 204 in response to the ALLOCATION message 312.
- DTMF Dual Tone Multi- Frequency
- a control signalling link between the user port 73 and the service node 204 may be maintained over the V5.2 interface for supervising the traffic connection between the user 202 and the access resource 212a.
- one of the channels in the V5.2 interface is used for such control signalling of several users.
- the call will end when the user initiates a release of the call using a conventional release procedure defined for PSTN.
- the connection is a ISDN connection a corresponding procedure is initiated.
- the connection with the access resource 212a is released by sending a DE-ALLOCATE message 316 from the service node 204 to the access network 200, which replies with a DE-ALLOCATE COMPLETE message 318.
- a fault will be indicated to the manager of the access resource 212a, which in turn will generate an AN-FAULT message ⁇ to the access network 200.
- This function is useful, since the service node ' 204 may mistakenly specify an address identity in the ALLOCATION message 312 which is not defined' in the access network 200.
