Definitions

  • the subject matter described herein relates to methods and systems for providing uniform resource identifier mapping in a communications network. More particularly, the subject matter described herein relates to methods, systems, and computer program products for providing a universal uniform resource identifier (UURI).
  • UURI universal uniform resource identifier
  • IP Internet protocol
  • IMS Internet protocol multimedia subsystem
  • 3GPP Third Generation Partnership Project
  • IMS IP multimedia subsystem
  • 3GPP Third Generation Partnership Project
  • IMS bridges the gap between the existing traditional telecommunications technology and Internet technology, allowing network operators to offer a standardized, reusable platform that can be used to provide services for both mobile networks and landline networks at the same time, providing unique mixtures of services with transparency to the end user.
  • IMS uses the session initiation protocol (SIP) for initiating, modifying, and terminating an interactive user session that involves multimedia elements, such as video, voice, instant messaging, online games, and virtual reality, and provides the service creator the ability to combine services in the same session and dynamically modify sessions "on the fly” (e.g., adding a video component to an existing voice session).
  • SIP session initiation protocol
  • new and innovative user-to-user and multi-user services become available, such as enhanced voice services, video telephony, chat, push-to-talk, and multimedia conferencing, all of which are based on the concept of a multimedia session.
  • an IMS subscriber may want to send an email to a cell phone or place a telephone call using a computer -just two examples of the blurring of the lines between the formerly distinct and incompatible telephone and computer networks.
  • Even with merged networks however, there are still some disadvantages and inconveniences, which are holdovers from a time when telephone and computer networks were separate entities.
  • One such disadvantage is the continued need to maintain multiple pieces of contact information (e.g., telephone number, cell phone number, email address, instant message address, etc.) for each person in a subscriber's contact list. For example, subscriber A cannot send an email to subscriber B, unless A knows B's email address.
  • IMS subscriber e.g., voice, email, messaging, multimedia, etc.

  • Table 1 displays an example SIP message format.
  • UURI associated with a subscriber
  • SIP start line "Request URI” field
  • SIP general header To:” field
  • SIP general header From:” field
  • a media type indicator may be included in the SIP general header "Content-Type" field. If the message body is in the multipurpose Internet mail extensions (MIME) format, the media type indicator may be found in the MIME "Content-Type:” header. For example, a MIME- encoded voice mail might have the MIME header "Content-Type: audio/mpeg”.
  • MIME multipurpose Internet mail extensions

  • the image data would be sent for example to User's handheld personal digital assistant.
  • the last row in Table 2 might be used as the default or fallback case, to be used for example if the media type included in the message doesn't match any entry in Table 2, or when a URI in the table doesn't respond, as might be the situation if User's VOIP connection is off line, in which case the audio message should be sent to User's regular telephone or voicemail account.
  • FIG. 2 is a block diagram illustrating an exemplary system for mapping a universal uniform resource identifier (UURI) to a uniform resource identifier (URI) in accordance with an embodiment of the subject matter described herein.
  • the system may include a universal URI resolution function URF 200 for resolving a universal uniform resource identifier
  • UURI uniform resource indicator
  • URF 200 may identify a uniform resource indicator (URI) based on the UURI and media type indicator, and send a message containing the identified URI.
  • URI uniform resource indicator
  • a call session control function CSCF 202 may receive a message, such as a SIP INVITE message ( Figure 2, message 1).
  • the message may include a UURI.
  • the UURI may be part of the SIP "Request-URl:” field or the SIP “To:” field.
  • the SIP message may also include a media type indicator, such as the SIP "Content-Type:” field.
  • CSCF 202 may send a query to URF 200 and receive a response from URF 200.
  • CSCF 202 may detect that the incoming message includes a UURI (in the Request-URl: field) and a media type indicator (in the Content-Type: field) and send to URF 200 a URF query message containing a UURI associated with a subscriber and also containing a media type indicator indicating a media type. ( Figure 2, message 2).
  • URF 200 may resolve the UURI to the appropriate URI based on the media type.
  • URF 200 may perform a table lookup using a table such as Table 2, above.
  • URF 200 may send a response message containing the URI associated with the subscriber and the media type indicator ( Figure 2, message 3) back to CSCF 202.
  • CSCF 202 may then replace the UURI in the original message with the URI returned by URF 200 and send the message containing the identified URI to the message's destination ( Figure 2, message 4).
  • URF 200 performs a query/response function: URF 200 receives a query message from a querying entity, such as CSCF 202, performs the UURI resolution function, and sends a response message containing the identified URI back to the querying entity.
  • CSCF 202 may not be adapted to or may be unable to detect the presence of a UURI in the received SIP INVITE message (Figure 2, message 1), and may by default initiate an associated URF query transaction (similar to that described above).
  • FIG 3 is a block diagram illustrating an exemplary system for mapping a universal uniform resource identifier (UURI) to a uniform resource identifier (URI) in accordance with another embodiment of the subject matter described herein.
  • UURI universal uniform resource identifier
  • URI uniform resource identifier
  • URF 200 may identify a URI based on the UURI associated with the subscriber and on the media type indicator and then send a message containing the identified URI to the message's destination ( Figure 3, message 3).
  • URF 200 performs a message receive/modify/forward function: URF 200 receives a message from a source entity, such as CSCF 202, performs the UURI resolution function, and sends a message containing the identified URI to a destination entity that is different from the source entity.
  • the message sent to the destination entity may be an entirely new message, or it may be identical to the received message but with the UURI replaced by the identified URI. In this manner, network traffic is reduced when compared to the embodiment shown in Figure 2.
  • Figures 4 and 5 illustrate a block diagram of an exemplary system for mapping a universal uniform resource identifier (UURI) to a uniform resource identifier (URI) operating in conjunction with a presence function for determining the on-line availability of a subscriber associated with the UURI in accordance with yet another embodiment of the subject matter described herein.
  • Figure 4 illustrates an exemplary behavior of the system when the subscriber associated with the UURI is available
  • Figure 5 illustrates an exemplary behavior of the system when the subscriber associated with the UURI is not available.
  • the subscriber in this example is assumed to have two types of telephone: a VOIP phone, which is connected to the Internet, and another phone connected to a traditional telephone network such as a PSTN network. It is also assumed that the subscriber prefers to receive voice calls on her VOIP phone if she is currently on-line (i.e., connected to the Internet) and on her other phone if she is not currently on-line.
  • Figure 4 illustrates an exemplary behavior of the system when the subscriber associated with the UURI is available.
  • a message containing a UURI associated with a subscriber and also containing a media type indicator indicating a media type, such as a SIP INVITE message ( Figure 4, message 1) is received by CSCF 202.
  • the SIP invitation specifies that the content type is "audio", indicating that the invitation is to create a voice session or voice call.
  • CSCF 202 may send a UURI resolution function query (Figure 4, message 2) to URF 200.
  • Figure 4, message 2 the UURI "user@Tekelec.com” has two URIs associated with the media type "Audio”: the first is “sip:userVOIP@vzw.com”, used for VOIP calls, and the second is "tel:9194605500", used for traditional telephone calls.
  • URF 200 may first resolve the UURI and media type and determine that the URI "userVOIP@vzw.com” should be used.
  • URF 200 may then determine the presence status of the subscriber associated with the URI. For example, URF 200 may issue a message, such as a subscribe request ( Figure 4, message 3), to a presence function 400. Presence function 400 may return a message indicating the current status of the subscriber associated with the URI ( Figure 4, message 4).
  • a message such as a subscribe request ( Figure 4, message 3)
  • Presence function 400 may return a message indicating the current status of the subscriber associated with the URI ( Figure 4, message 4).
  • URF 200 may respond to the URF query with a message containing the subscriber's VOIP URI ( Figure 4, message 5).
  • CSCF 202 may then replace the UURI in the original message with the VOIP URI, and issue the modified message to the message's destination ( Figure 4, message 6).
  • Figure 5 illustrates an exemplary behavior of the system when the subscriber associated with the UURI is not available.
  • the operation and response of the system to the first three messages are identical to the example described in Figure 4; that explanation will not be duplicated here.
  • presence function 400 returns a message indicating that the subscriber associated with the URI is not available ( Figure 5, message 4).
  • URF 200 may determine that an alternate, fallback, or default URI is available for the specified media type. For example, referring again to Table 2, above, URF 200 may resolve the UURI and media type to the URI "tel:9194605500", and respond to the URF query with a message containing the subscriber's PSTN or mobile telephone number (Figure 5, message 5). CSCF 202 may then replace the UURI in the original message with the subscriber's telephone number, and issue the modified message to the message's destination ( Figure 5, message 6).
  • CSCF 202 may be performed by another network element or another type of network element, such as a SIP router, a SIP proxy, or other SIP node, for example.
