Definitions

  • the present invention relates generally to a method and apparatus for handling emergency calls in a multimedia service network.
  • the invention is concerned with obtaining required location information for a calling subscriber.
  • emergency services are available for subscribers in situations of emergency, such as accidents and diseases.
  • Emergency calls are typically first routed to an emergency centre which then connects the calls further to relevant emergency service stations, depending on the current situation, e.g. a hospital, a fire station or the police.
  • emergency services are subject to regulations prevailing in different countries and regions.
  • the telephony system can provide relevant location information in order to certify the location of the calling party. Firstly, it may be important to connect an incoming call to an emergency centre or service station being reasonably close to the caller. Secondly, the caller may not for some reason be able to provide crucial information regarding his/her whereabouts to the emergency centre, at least not immediately.
  • local exchange 102 has knowledge of subscriber terminal A being connected to a specific input line in the exchange, which is associated with a specific calling party identifier of subscriber terminal A. The local exchange 102 is thus required to supply the calling party identifier of subscriber terminal A when transmitting the emergency call to emergency centre 104 .
  • location database 106 the geographic location of subscriber terminal A is stored together with its calling party identifier, such that the emergency centre 104 can retrieve that location information from the location database 106 by means of the calling party identifier received with the emergency call.
  • a serving Mobile Switching Centre MSC can include location information in emergency calls from mobile terminals, such as a cell identification or even more accurate information in the form of geographic coordinates or the like based on location services employed in the network. Further, the receiving emergency centre may also use specific location services to determine the location of the calling party, if necessary.
  • IP Internet Protocol
  • Multimedia services typically entail IP based transmission of encoded data representing media in different formats and combinations, including audio, video, images, text, documents, animations, etc.
  • IMS IP Multimedia Subsystem
  • 3GPP 3rd Generation Partnership Project
  • IMS networks can also be used to provide emergency services, although it is not evident how to provide relevant location information when required, due to the roaming possibilities for IP terminals, and this issue has not yet been solved.
  • IMS is a platform for enabling services based on IP transport more or less independent of the access technology used, and will be briefly outlined here.
  • the IMS network is thus used for generally controlling multimedia sessions, and a specification called “SIP” (Session Initiation Protocol, according to the standard IETF RFC 3261) is used for handling multimedia sessions in IMS networks.
  • SIP Session Initiation Protocol
  • SIP is an application-layer protocol used by IMS networks and terminals to establish and control IP based multimedia communications.
  • an addressing element called “SIP URI” When sending SIP messages, an addressing element called “SIP URI” (Uniform Resource Identifier) is used, such that one SIP URI indicates the source and another one indicates the destination in each message.
  • FIG. 2 is an exemplary schematic illustration of a basic scenario when multimedia services are provided for a terminal A by means of an IMS service network.
  • Terminal A is connected to an IP access network 200 and communicates media with a remote party B, such as another terminal or server, in a communication session S.
  • An IMS network 202 A is connected to the IP access network 200 and handles the session with respect to terminal A, where networks 200 and 202 are typically owned by the same operator.
  • multimedia services are handled by the terminal's “home” IMS network, i.e. where it is registered as a subscriber.
  • the remote party B may be connected to another corresponding IMS network 202 B.
  • the illustrated session S is basically managed by a node called S-CSCF (Serving Call Session Control Function) 204 assigned to terminal A in the IMS network 202 A, and the used multimedia service is enabled and executed by an application server 206 connected to the IMS network 202 .
  • S-CSCF Serving Call Session Control Function
  • the S-CSCF node 204 serves as a proxy for the application server 206 towards terminal A, and sends SIP messages coming from terminal A towards the remote party B, as indicated by a dashed arrow.
  • a main database element HSS (Home Subscriber Server) 208 stores subscriber and authentication data as well as service information, among other things, that the SIP application server 206 can fetch for executing services for subscribers.
  • I-CSCF Interrogating Call Session Control Function
  • IMS network 202 A node called I-CSCF (Interrogating Call Session Control Function) 210 in IMS network 202 is connected to other IMS networks, including network 202 B, and acts as a gateway for SIP messages arriving from such IMS networks.
  • I-CSCF 210 receives SIP messages concerning the remote party B, as indicated by another dashed arrow.
  • P-CSCF Proxy Call Session Control Function
  • the IMS network 202 contains numerous other nodes and functions, such as further S-CSCF nodes and SIP application servers, which are not shown here for the sake of simplicity.
  • the object of the present invention is to address at least some of the problems outlined above, and to provide a solution for enabling the supply of location information for a subscriber to an emergency centre in connection with an emergency call, when connected to an IP access network.
  • This object and others may be obtained by providing a method and apparatus according to the attached independent claims.
  • the present invention provides a method, executed in a multimedia service network, of obtaining location information for subscribers connected to an IP access network.
  • a location query including said IP address is sent to the IP access network.
  • Location information for the subscriber is then received therefrom in response to the location query, thereby enabling supply of the received location information in connection with an emergency call from said subscriber.
  • the obtained location information is added to the request before sending it to an emergency centre.
  • the emergency centre may be selected for the request based on the obtained location information.
  • the multimedia service network may be an IMS network using SIP signalling, and the request relating to an emergency call is then typically an SIP INVITE message.
  • the obtained location information may be saved for later retrieval in the case of a subsequent emergency call from the subscriber.
  • the multimedia service network is an IMS network using SIP signalling
  • the registration request is typically an SIP REGISTER message.
  • the method can be executed in an IMS core entity such as a P-CSCF node in the IMS network.
  • the location query above may be sent to a location retrieval unit in the IP access network, which may also be referred to as a Location Query Function.
  • the present invention provides an arrangement in a multimedia service network, for obtaining location information for subscribers connected to an IP access network.
  • the inventive arrangement comprises means for receiving a request from a subscriber containing an IP address currently assigned to the subscriber, means for sending a location query including said IP address to the IP access network, and means for receiving location information for the subscriber in response to the location query.
  • the received location information can be supplied in connection with an emergency call from said subscriber.
  • the multimedia service network arrangement may further comprise logic means for determining whether the received request relates to an emergency call, and means for adding the obtained location information to the request before sending it to an emergency centre.
  • the logic means may be configured to select the emergency centre for the request based on the obtained location information. If the multimedia service network is an IMS network using SIP signalling, the request relating to an emergency call may be an SIP INVITE message.
  • the multimedia service network arrangement may further comprise logic means for determining whether the received request is a registration request, and means for storing the obtained location information for later retrieval in the case of a subsequent emergency call from the subscriber. If the multimedia service network is an IMS network using SIP signalling, the registration request is typically an SIP REGISTER message.
  • the arrangement can be implemented in an IMS core entity such as a P-CSCF node in the IMS network.
  • the sending means may be configured to send the location query to a location retrieval unit in the IP access network, which may also be referred to as a Location Query Function.
  • the present invention provides a method, executed in an IP access network, of providing location information to a multimedia service network for subscribers connected to said IP access network.

If the multimedia service network is an IMS network, the retrieved location information may be provided to an IMS core entity such as a P-CSCF node in the IMS network.
  • the present invention provides a location retrieval unit in an IP access network, which may also be referred to as a Location Query Function, for providing location information to a multimedia service network for subscribers connected to the IP access network.

  • the present invention provides a solution for obtaining location information for a subscriber connected to an IP access network, in order to enable supply of the location information to an emergency centre in connection with an emergency call from said subscriber.
  • This solution will now be described, initially with reference to FIG. 3 .
  • a subscriber A operating a fixed terminal capable of IP communication, is connected to an IP access network 300 at a certain point of access.
  • Access network 300 is further connected to a multimedia service network 302 , in this case an IMS network like the one described above for FIG. 2 , in which only an IMS core 304 is illustrated here.
  • the IMS core 304 is an entity basically representing a session managing node used for handling messages from subscriber A, preferably a P-CSCF node.
  • the IP access network 300 may be configured for so-called fixed broadband access typically used for multimedia services, although the present invention is generally not limited in this respect.
  • the IP access network 300 comprises a location retrieval unit 306 , an IP address administrator 308 and a location database 310 , where the latter two nodes or similar may typically occur in any IP access network.
  • the location retrieval unit 306 is also sometimes referred to as a “Location query function”.
  • the IP address administrator 308 assigns IP addresses to subscriber terminals for a limited time period upon request, e.g. when powered-on, and has knowledge of at which point of access in the network an IP address is currently used.
  • Each point of access in the network 300 may be identified by means of a layer 2 address such as an Ethernet MAC (Medium Access Control) address, ATM VPI/VCI (Asynchronous Transfer Mode, Virtual Path Identifier/Virtual Channel Identifier) or other relevant network address, depending on the network configuration.
  • the location database 310 stores information on the physical location for each point of access in the network 300 , such as a street address, geographic coordinates or the like.
  • the subscriber may basically bring his/her IP communication terminal to any point of access in the network, e.g. to public sites such as hotels and airports, or to more private quarters.
  • a subscriber may have different IP addresses at different occasions, which is administrated by the IP address administrator 308 .
  • a first step 3 : 1 in the figure illustrates that the IMS core 304 in network 300 receives a multimedia request from subscriber A, being at a location unknown so far.
  • the request contains an IP address currently assigned to the subscriber, and the request may be a session invitation such as an SIP INVITE message. Since the present solution is concerned with emergency calls, the received request may primarily be a session invitation for an emergency call that should be routed to a suitable emergency centre. However, the request may alternatively be a regular registration request that is typically sent to a multimedia service network after an IP terminal has been powered-on, without requesting a session. In IMS systems where SIP signalling is used, this would typically be a message called SIP REGISTER.
  • the IMS network 302 is obliged to retrieve and add such location information to the request when transmitting it further to the emergency centre.
  • the IMS network 302 may retrieve and store the location information in order to supply it at a later occasion, if a subsequent emergency request should arise from the same subscriber.
  • the emergency centre may request for updated location information, which however lies outside the scope of the present invention.
  • IMS core 304 sends a location query including the IP address received in the request, to the location retrieval unit 306 in network 300 , effectively asking for the location of the subscriber currently using the given IP address.
  • unit 306 retrieves the identity of the point of access at which the subscriber currently using the IP address is connected, from the IP address administrator 308 , in a step 3 : 3 .
  • Unit 306 may receive the point of access identity as a layer 2 address or other network address, depending on the network configuration, as mentioned above.
  • unit 306 can now retrieve the physical location for that point of access identity from location database 310 , e.g. as a street address or similar or geographical coordinates, in a further step 3 : 4 .
  • location database 310 e.g. as a street address or similar or geographical coordinates
  • the physical location may already be given from the IP address administrator in step 3 : 3 , thereby making step 3 : 4 superfluous.
  • the location retrieval unit 306 is now able to respond to the location query of step 3 : 2 by providing the obtained location information to IMS core 304 , in a following step 3 : 5 .
  • IMS core 304 is able to add the received location information to the request of step 3 : 1 from subscriber A, if required, and send it further to an emergency centre as indicated by a final optional step 3 : 6 .
  • IMS core 304 may just store the location information for later use in the case of an emergency request from subscriber A, as mentioned above, naturally without adding it to the registration request.
  • the above described solution makes it possible to obtain and supply required location information in connection with emergency calls over a multimedia service network coming from subscribers connected to an IP access network.
  • a procedure for obtaining location information for a subscriber connected to an IP access network will now be described with reference to the flow chart in FIG. 4 .
  • the steps in the flow chart are defined for execution in a multimedia service network, particularly in an IMS core entity such as a P-CSCF node.
  • a multimedia request is initially received from the subscriber containing an IP address currently assigned to the subscriber.
  • a location query for the received IP address is sent in a next step 402 to the IP access network, preferably to a location retrieval unit or similar therein, like the unit 306 shown in FIG. 3 .
  • relevant location information is received therefrom, in following step 404 .
  • step 406 it is determined in a step 406 whether the received request relates to an emergency call, i.e. directed to an emergency service that is requested in a session invitation for an emergency call from the subscriber. If so, the location information received in step 404 is added to the emergency call request in a further step 408 before sending the request to an emergency centre. It should be noted that the obtained location information may be used for selecting a suitable emergency centre, e.g. located in the same region as the subscriber's current location.
  • step 406 If it is determined in step 406 that the received request is not related to an emergency call, such as in the case of a registration request, the obtained location information is stored in a final illustrated step 410 for later use if the subscriber should make an emergency call, instead of adding it to the request received in step 400 .
  • this procedure may be simplified by executing the determination step 406 directly after the first step 400 of receiving the request. Then, only if the request is related to an emergency call, the location information may be obtained and supplied by executing steps 402 , 404 and 408 , and the storing step 410 may be omitted. In this alternative, no further steps are taken for location retrieval if the request is not related to an emergency call.
  • step 508 can be executed immediately after step 504 , as indicated.
  • the location retrieval unit 700 comprises receiving means 702 configured to receive location queries Q from a multimedia service network, each query containing an IP address assigned to a subscriber.
  • Unit 700 further comprises retrieving means 704 configured to retrieve location information L based on said IP addresses, from an IP address administrator and optionally a location database in the IP access network.
  • Unit 700 further comprises providing means 706 configured to provide retrieved location information L for subscribers to the multimedia service network in response to received location queries Q.
  • the present invention offers a simple yet reliable mechanism for obtaining required location information and for providing it to an emergency centre, in response to emergency requests from subscribers connected to an IP access network and requesting emergency services from a multimedia service network.
