Definitions
- FIG. 1 provides a schematic diagram of a conventional communication system which can provide communication services to a communication terminal.
- the communication terminal may be a mobile device such as a portable personal computer or a portable telephone.
- the system includes a packet data network 1 which comprises a number of network nodes 2, 3, 4, 5, 6, 7, 8, 9 and a path computational element 10.
- the network nodes typically comprise network elements such as routers and switches which direct data packets across the packet data network 1.
- the network nodes are controlled by a path computational element (PCE) 10.
- the PCE 10 is a module within the packet data network which can control the nodes to determine how and by which route (data paths) packet data is transmitted across the network.
- a route i.e. a data path
- the PCE 10 can be defined by the PCE 10.
- thin lines 17 connecting the network nodes illustrate interconnections between the nodes. These interconnections provide a number of different potential data paths via which packet data can be communicated to and from the application server
- a communication terminal 13 requests a communication service from an application server providing a "real-time" service such as voice over IP which requires packets to be transmitted from user to server as quickly as possible
- the PCE 10 could be arranged to designate a data path that minimises latency and packet loss.
- the communication terminal wishes to access an application which requires a large amount of data to be communicated such as downloading or streaming media data such as video or audio data
- the PCE 10 could be arranged to designate a data path that provides a bandwidth sufficient to ensure that it does not lake an undesirably long period of time for the audio or video data to be communicated from the application server to the communication terminal.
- Figure 3 shows a flow of messages between the communication terminal 13, the IMS 34 and the PCE 10 which enables the data path to be calculated by the PCE 10 taking into account requirements of a communication service provided by the application server.
- the communication terminal 13 in order for the communication terminal 13 to access a communication service provided by the application server 12, the communication terminal 13 initiate a communicate request in the form of a SIP INVITE request 31 to the CSCF 1 L, the CSCF 11 forwards the INVITE request 32 to the application server 12.
- the application server 13 is operable to respond with an adaptation message 33 transmitted to the PCE 10.
- the adaptation message may contain information indicating the type of communication service provided by the application server along with other parameters such as quality of service requirements and so on.
- Both the fixed and dynamic information may be used to determine whether, irrespective of any adaptation of the network by the PCE, the current conditions within the network are good enough to support a particular application. For example, if an application provided by an application server requires a very high bandwidth, there may not be enough high bandwidth links available to form a suitable data path. In some cases therefore, upon receipt of the adaptation message 33, the PCE 10 may be operable to compare service quality requirements specified in the adaptation message with the available service quality that the network can provide. If the service quality requirements specified within the adaptation message 33 cannot be met or a suitable data path cannot be provided, the PCE 10 may be operable to communicate this back to the IMS 14 which may then take appropriate action. This action might include, rejecting the original request to set up the communication session between the application server and the communication terminal. The IMS may also transmit a suitable error message to be forwarded to the communication terminal and the application server.
