A method of establishing a communication event in a communication system from an initiator device to one of a plurality of entities associated with the initiator device comprising assigning a calling identity to at least one of said entities at a first network node associated with a packet switched network; providing the assigned identity to the initiator device; storing associated contact information for the entity together with the calling identity assigned to the entity at a second network node associated with the packet switched network, initiating a communication event from the initiator device to the entity via a circuit switched network by transmitting the identity assigned to the entity to a gateway node; sending a message to the second network node with the identity assigned to the entity to determine the contact information for the entity; and routing the communication event from the gateway node to the entity using the determined contact information via one of the circuit switched and packet switched networks without said communication event being routed via said first network node.
This application claims priority under 35 U.S.C. §119 or 365 to Great Britain Application No. 0623622.8, filed Nov. 27, 2006 and Great Britain Application 0723123.6 filed Nov. 23, 2007. The entire teachings of the above applications are incorporated herein by reference.
In a communication system a communication network is provided, which can connect two communication terminals so that the terminals can send information to each other in a call or other communication event. Information may include voice, text, images or video.
One such communication system is a peer to peer communication system, in which a plurality of end users can be connected for communication purposes via a communications structure such as the internet using peer to peer client software. The communications structure is substantially decentralised with regard to communication route switching therein for connecting the end users. That is, the end users can establish their own communication routes through the structure based on exchange of one or more authentication certificates (user identity certificates—UIC) to acquire access to the structure. The structure includes an administration arrangement issuing the certificates to the end users. Such a communication system is described in WO 2005/009019.
Peer-to-peer communications are beneficial to the user as they are often of significantly lower cost than traditional communication networks, such as fixed line or mobile networks. This may particularly be the case for long distance calls. These systems may utilise voice over internet protocol (“VoIP”) over an existing network (e.g. the Internet) to provide these services, although alternative protocols can also be used.
In a communication system, such as a peer to peer system, client software is installed on an end user device such as a personal computer (PC) to allow the end user to communicate via the communications network and to identify the user within the communication network. The user interface of the client software can be controlled by the client to display user facilities and to indicate events occurring, such as an incoming call. FIG. 1A is a diagram of an end user device 10 running client software to communicate directly with the peer to peer system. The client software comprises a user interface layer 12, a client engine layer 14, and a protocol layer. The protocol layer is arranged to handle the communication between the client engine and the peer to peer system 104.
Users may be accustomed to mobility whilst using conventional telephony services, due to the prevalence of cordless phones and mobile cellular networks. It is therefore desirable to run the client software on mobile devices such as a mobile phone or other battery operated cordless device. However, running the client software on a mobile end user device presents a number of problems. Hand held mobile devices are typically battery operated and have less CPU resource than a PC. The power requirement used to run the client software to handle the communications can reduce the battery life considerably for battery operated devices. Furthermore, running the client software on the user device may use valuable CPU resources that are required to run other applications on the device.
One further problem caused by using a mobile device in an VoIP communication system is that in a VoIP system such as a peer to peer system, it is necessary to be constantly connected to the internet in order to be notified of communication events, such as receiving a call. Maintaining a constant connection between the communication network and the internet is not only an inefficient use of battery life and CPU resources of the device, but also an inefficient use of network connection resources. Also being constantly connected to the internet may be costly for a user. Furthermore the quality of the connection to the internet may be poor therefore degrading the quality of the communication.
According to a first aspect of the present invention there is provided a method of establishing a communication event in a communication system from an initiator device to one of a plurality of entities associated with the initiator device comprising: assigning a calling identity to at least one of said entities at a first network node associated with a packet switched network; providing the assigned identity to the initiator device; storing associated contact information for the entity together with the calling identity assigned to the entity at a second network node associated with the packet switched network, initiating a communication event from the initiator device to the entity via a circuit switched network by transmitting the identity assigned to the entity to a gateway node; sending a message to the second network node with the identity assigned to the entity to determine the contact information for the entity; and routing the communication event from the gateway node to the entity using the determined contact information via one of the circuit switched and packet switched networks without said communication event being routed via said first network node.
According to a second aspect of the present invention there is provided a communication system comprising a packet switched network and a circuit switched network for routing a communication event from an initiator device to one of a plurality of entities associated with the initiator device the communication system comprising: a first network node located in the packet switched network arranged to assign a calling identity to at least one of said entities and to provide the assigned identity to the initiator device; a second network node located in the packet switched network arranged to store associated contact information for the entity together with the calling identity assigned to the entity; a gateway node arranged to receive the communication event addressed using the calling identity assigned to the entity from the initiator device via the circuit switched network; wherein the second network node is further arranged to determine the contact information for the entity in response to receiving a message with the identity assigned to the entity and to provide the contact information to the gateway node such that the communication event may be routed from the gateway node to the entity via one of the circuit switched and packet switched networks without said communication event being routed via said first network node.
According to a third aspect of the present invention there is provided a network node for use in a communication system comprising: means for providing a calling identity to be allocated to an entity to another network node located in the communication system; means for receiving allocation information and contact details for the entity from the other network node; means for storing the calling identity for an entity in association with contact details for the entity using the allocation information; means for receiving calling information for a call initiated by an initiator device, said calling information comprising the calling identity; means for retrieving the contact details for the entity based on the received the calling information; and means for providing the contact details of the receiving the device to a routing node route the call the entity.
FIG. 3 a is a diagram showing a user device in accordance with an embodiment of the present invention;
FIG. 3 b is a diagram showing the protocol stack of a client program in accordance with an embodiment of the present invention;
Reference will first be made to FIG. 1, in which is shown a communication network 100, including a packet switched communication system 104 and circuit switched networks 112 and 120. In one embodiment the packet switched communication system 104 may be a peer to peer system operating on a packet switched network such as the internet. The circuit switched networks 112, 120 may comprise PSTN (Public Switched Telephone Network) networks.
A user device 102 is shown to be connected to the peer to peer system 104 via a session node 106. The user device 102 is also connected to the PSTN network 120. In one embodiment of the invention the user device is connected to the circuit switched network 112 via a circuit switched connection 222 and to the session node 106 via a packet switched connection 111. The circuit switched connection 222 and the packet switched connection 111 may be provided by a GSM (Global System for Mobile Communications) network (not shown). For example the packet switched connection may be provided by a GPRS (General Packet Radio Service) connection of the GSM network whilst the circuit switched connection may be provided by a GSM audio connection of the GSM network. In a preferred embodiment of the invention the packet switched connection 111 is used to transmit packet data according to an internet protocol such as Transmission Control Protocol (TCP).
The user device 102 runs a client software program 124 that provides a client interface on the device and allows the user device to communicate with the session node 106. The session node 106 runs a communication instance 122 defining a session dedicated to the user device 102. The communication instance 122 enables the user device 102 to communicate with the peer to peer communication system 104. The communication instance also includes a protocol adaptor instance which enables the communication instance 122 to communicate with the client program 124. The session node 106 is able to run a plurality of communication instances for a number of concurrent user devices (not shown).
The client program 124 running on the user device has a number of different components or layers for implementing various functions, including a protocol layer 402 (FIG. 3 b) for managing the interface with the GSM network. The interface with the GSM network will now be described with reference to FIG. 3 a.
FIG. 3 a is a schematic diagram showing the transmission of data between the client program 124 and a GSM protocol stack in the user device 102. As shown in FIG. 3 a the user device 102 further comprises the GSM protocol stack 501 and a radio transceiver 502. Information transmitted from the GSM network to the user device is received by the transceiver 502. The data received from the GSM network is processed by GSM protocol stack 501 before it is transmitted to the client program 124. Similarly, information to be transmitted to the GSM network from the client program 124 is processed by the GSM protocol stack 501 before it is transmitted to the GSM network via the transceiver 502. The operation of the GSM protocol stack 501 is known in the art and will not be described in detail herein.
As shown in FIG. 1 the peer to peer system 104 comprises an inbound gateway 114 and an outbound gateway 116. The inbound gateway 114 and the outbound gateway 116 are connected to PSTN gateways 188 located in the PSTN networks. The inbound gateway 114 is arranged to receive data for the peer to peer system on the internet 104 from the PSTN gateways 188. The outbound gateway 116 is arranged to transmit data from the peer to peer system on the internet 104 to the to the PSTN gateways 188.
A call manager 118 is connected between the session node 106 and the inbound gateway 114. In FIG. 1 the call manager 118 is shown as being located separately from the session node 106 and the inbound gateway 114. The call manager 118 may however form part of either the session node 106 or the inbound gateway 114. The operation of the call manager 118 will be explained hereinafter.
Also shown in FIG. 1 is a profile node 128. The profile node 128 is responsible for storing user profile information for users of the peer to peer system. The user profile information includes login information for logging into the peer to peer system and a contact list 132 associated with each user of the peer to peer system.
The contact list 132 comprises the addresses of, for example, other users of the communication system stored as contacts by a user. The contact information may define a telephone number, an IP (Internet Protocol) address, a URI (Uniform Resource Indicator), a username, a VoIP device or any other destination address capable of receiving a communication event across the communication network 100. In one embodiment of the invention the contact information for the list of contacts may comprise a list of destination addresses within the internet.
Reference will now be made to FIG. 2 which shows a more detailed diagram of part of the communication system 100. Components of the communication system 100 described in relation to FIG. 1 that are also shown in FIG. 2 are labelled with common reference numerals. Additionally shown in FIG. 2 are a circuit switched network access node 178 and a PSTN network gateway 188 and a data store 126 associated with the session node 106. The access node 178 and the PSTN gateway 188 form part of the circuit switched network 112. The storage device 126 is associated with the call manager.
Reference will now be made to FIG. 3 b. FIG. 3 b shows a protocol stack for the client program 124 according to an embodiment of the present invention. The protocol stack shows an operating system layer 401, a protocol layer 402, a client engine layer 404 and a client user interface layer 406. Each layer is responsible for specific functions. Because each layer usually communicates with two other layers, they are regarded as being arranged in a stack as shown in FIG. 3 b.
The operating system layer 401 manages the hardware resources of the user device 102 and handles data being transmitted to and from the session node 106 via the GSM protocol stack. The operating system layer also handles the data being transmitted to and from the network 112 via the GSM protocol stack. The client protocol layer 402 of the client software communicates with the operating system 401. Processes requiring higher level processing are passed to the client engine layer 404. The client engine 404 also communicates with the user client user interface layer 406. The client engine may be arranged to control the client user interface layer 406 to present information to the user via user interface means of the user device and to receive information from the user via the user interface means of the user device. The user interface means may comprise a speaker, a microphone, a display screen and a keyboard. This list is not exhaustive.
The communication instance 122 running on the session node 106 enables the communication between the client program 124 running on the device 102 and the peer to peer system 104. FIG. 4 shows the connection path between the communication instance 122 on the session node 106 and the client program 124 running on the user device 102.
As shown in FIG. 4, the session node 106 comprises a core module 205 for allocating a communication instance 122 to a client program 124. In accordance with an embodiment of the invention, when a client program 124 transmits a login request to the session node 106, the core module 205 is arranged to assign a communication instance 122 to the client program 124.
It is possible that the protocol layer 402 of the client 124 uses a different protocol to the protocol used within the communication instance 122. The protocol adaptor in the communication instance facilitates the communication between the client program 124 and the communication instance 122.
It will be apparent that in contrast to FIG. 1 a, the device 102 runs only the user interface part of the software; The communication part responsible for communicating with the peer to peer network is executed at the session node 106, not at the device 102. Thus device 102 consumes less battery and CPU resource.
The client program 124 communicates with the session node 106 via a packet switched data connection 111. The client program 124 may communicate with the session node 106 using TCP (Transmission Control Protocol) or other suitable internet protocol.
In accordance with an embodiment of the invention the client program 124 is arranged to log in the peer to peer system 104 by transmitting login details such as a user login name and password to the session node 106 over the data connection 111. On receipt of log in details the session node is arranged to assign a communication instance 122 to the client program 124. The communication instance 122 is then arranged to check the login details with the user's profile information stored on the profile node 128 and to sign in to the peer to peer system 104 using the login details.
When a communication instance is assigned to a user device, this defines a session between the client program 124 and the session node 106 for communicating with the peer to peer system 104. The communication instance generates a session identifier and transmits the session identifier to the client program 124 over the data connection 111.
When a session is initiated for a user device 102 the communication instance 122 running on the session node 106 is arranged to retrieve the contact list 132 associated with the user of the client program 124 and to send at least part of the contact list 132 to the client program 124. The contact list 132 can be retrieved by the communication instance from the profile node 128.
According to an embodiment of the invention a PSTN number is assigned to the each contact by communication instance to enable the client program to establish a call to a contact via the PSTN network. The method of assigning a PSTN number to a contact will now be described with reference to FIG. 5.
As previously stated, the client program 124 is arranged to receive information from the session node 106 via the packet switched connection 111. The client program 124 is arranged to use the allocated PSTN numbers transmitted over the packet switched connection 111 to initiate circuit switched calls to the contacts listed in the contact list 132′ using the GSM audio connection 222. It is an important aspect of the present invention that circuit switched data such as call data is not routed though the session node 106. However packet switched data, such as IM (Instant Messaging) and chat data, may be transmitted via the session node 106 using the URI of the contact.
In accordance with an embodiment of the invention, during a communication event to a contact using the calling identifier, the call manager 118 is arranged to retrieve the contact details of the contact from the data store 126 in response to receiving the calling identifier. The contact details retrieved by the call manager may be provided to the inbound gateway 114 to allow the communication event to be routed. The logical connections between the call manager 118 the session node 106 and the gateways 114, 116 are shown in FIG. 7.
A call comprises both a media data connection and a control data for handling the call set up. In FIG. 6 the control data connection for transmitting control data and the media data connection for transmitting the media data are shown separately. The control data connection is shown as a solid line and the call connection is shown as a broken line.
In an alternative embodiment of the present invention the entity that the user of the user device 102 places a call to is not listed as a contact in the contact list 132. In this embodiment of the invention the user device 102 is arranged to provide the communication instance 122 with the address of the entity via the data connection 111 before initiating a call with the entity. In this embodiment of the invention a PSTN number defined in the ‘call set up’ message described in relation to table 2 is reserved for an entity that is not listed in the contact list. When the communication instance receives the address of the entity from the user device, the address of the entity is stored in the data store 126 in association with the reserved PSTN number. A call may then be placed to the entity via the PSTN network in accordance with the method steps described in relation to FIG. 6.
According to one embodiment of the invention the call manager selects a PSTN number to assign in dependence on the location information of the user device 102. According to this embodiment the assigned number may be associated with an inbound gateway that is located geographically closer to the user device than other inbound gateways in the communication system, a so called “local number”.
In an alternative embodiment of the invention the PSTN number of the user device may not be available. In this embodiment of the invention the allocated PSTN number will correspond directly to the address of the contact. As such the call manager may resolve the address of the contact by searching the data store with the allocated PSTN number only.
In one embodiment of the invention the inbound gateway 114 may be arranged to not t accept the media data connection from the PSTN gateway 188. In this embodiment of the invention the inbound gateway 114 is arranged to provide the PSTN gateway 188 with the address of the contact such that the PSTN gateway may route the call via the PSTN network. This embodiment of the invention may be applied when the address of the contact is a PSTN number.
In one embodiment of the invention a contact listed in the contact list 132 may be associated with a plurality of locations in the communication system. For example a contact may be connected to the internet with using more that one device. According to this embodiment of the invention the contact details of the contact, for example the username of the contact will be associated with a plurality of locations in the internet. As such when the user of the user device establishes a call with the contact, the call may be received at the plurality of locations.
The data store 126 is shown to be associated with the call manager 118. However the data store can be geographically separate from the call manager 118. In an alternative embodiment of the invention the data store 126 may be associated with the session node and may be accessed by the call manager 118 via the session node. In a further alternative embodiment of the invention the data store may be located at session node 106. In a further embodiment of the invention the data store may be comprise to separate storage locations provided at the call manager 118 and the session node 106 respectively.
