Definitions

  • a Gateway Function that supports mobility or roaming between a Mobile IP-telephony Network (MIPTN) and a cellular network.
  • MIPTN Mobile IP-telephony Network
  • the subscriber's Home Function and Visited Function will be located in different types of networks.
  • the cellular network and the MIPTN are distinct and incompatible networks because different types of messages, signaling and addressing systems are used.
  • the Gateway Function performs the interworking between the PSTN/cellular message formats and signaling and those in the MIPTN.
  • Fig. 17 is a diagram illustrating an example delivery of a short message from a IP- telephony short message service center to a mobile cellular network subscriber that is roaming within the cellular network.
  • the Home Function 204 returns the MIPTN network address (e.g., IP address) of the MIPTN Visited Function where the subscriber can be reached (e.g., where the subscriber is registered).
  • the Gateway 21 1 then delivers the received PSTN call to the MIPTN subscriber by setting up an IP-telephony call towards the IP address of the serving MIPTN Visited Function. For a call received from another MIPTN subscriber (e.g., from MIPTN subscriber terminal 230), the Gateway 21 1 is not involved.
  • Fig. 3 is a block functional diagram illustrating a Mobile IP-telephony network Home Function according to an example embodiment of the present invention.
  • the MIPTN Home Function 204 includes a Call Processing Service (CPS) 410, a Location and Directory Service (LDS) 412 and a Home Function Database (HDB) 414.
  • HDB 414 stores subscriber profiles and location information for MIPTN subscribers (e.g., the IP address and port number of the Visited Function identifying where the subscriber can be reached).
  • the LDS 412 interfaces other entities to the HDB 414 by performing information storage and retrieval to HDB 414 upon request.
  • the HDB also maintains the mapping or correspondence between IMSI, MSISDN and the transport address of the serving Visited Function where the subscriber can be reached.
  • a calling entity or a standard IP-telephony gateway 211 also statically translates between the called subscriber identification (such as a MSISDN or IMSI) to an IP address of the subscriber's Home Function. (See, for example, static translation performed by standard Gateway 211 from MSISDN to MSISDN.
  • Visited Function can use a database or look-up table or other technique to statically translate the subscriber's IMSI to the transport address of the subscriber's Home Function 204.
  • a distributed technique such as Global Title Translation can be used to identify the actual IP address of the Home Function 204 based on the subscriber's IMSI.
  • the MIPTN Visited Function sends an update location message (e.g., packet or datagram) to the subscriber's MIPTN Home Function 204 and provides the transport address of the Visited Function (VF_TA) and the status of the subscriber.
  • the VF TA is the IP address at which the subscriber can be reached in the MIPTN 202.
  • the HDB 414 (Fig. 3) receives and stores the updated location information (e.g., VF TA) and status information for the subscriber.
  • the Visited Function may provide the CCEVF TA.
  • Fig. 10 is a diagram illustrating an example delivery of a PSTN call to a Mobile IP- telephony subscriber roaming in the Mobile IP-telephony network. It is assumed in Fig. 10 that the MIPTN subscriber has already contacted a MIPTN Visited Function to perform registration. The call delivery of a PSTN call to a MIPTN subscriber roaming in the MIPTN 202 is similar to the call delivery of a MIPTN call (shown in Fig. 9). It is not necessary to use Gateway Function 210 here (Gateway 21 1 will suffice) because this is not internetwork roaming (rather, Fig. 10 involves roaming within MIPTN 202).
  • an IP-telephony call is set up from the Gateway Function towards the address of the MIPTN Visited Function (with the media sent to either VF TA or RTP_TA address of the MIPTN Visited Function).
  • the Gateway Function 210 receives the status enquiry message (including the called subscriber's IMSI), and identifies the VLR number (identifying the serving VLR or cellular Visited Function where the subscriber has registered) corresponding to the subscriber IMSI (using the dynamic mapping obtained during registration).
  • the Gateway Function 210 sends a Route Number (RN) request message as a cellular procedure or message
  • the Gateway Function 210 receives the status response message of step 5 of Fig. 14. If the subscriber terminal is reachable or able to receive the call, the Gateway Function 210 assigns a roaming number (RN) to the subscriber terminal, and stores the correspondence between the IMSI and RN. (The Gateway Function has already stored the correspondence between the IMSI and the VF TA where the subscriber is registered or located). At step 6 of Fig. 14, the Gateway Function sends a RN response message to the cellular Home Function 266, providing the RN assigned to the called subscriber.
  • the message of step 6 is an example of the signaling of leg C of Fig. 15. Steps 7-11 of Fig. 14 will be briefly explained, and provide additional examples of call control signaling.
  • the Home Function then sends an alert message to the SMS GW 630.
  • the SMS GW 630 uses the dynamic mapping (MSISDN/ SMSC address) to identify the address of the SMSC (or the multiple SMSCs) that have messages to send to this subscriber.
  • the alert message is then forwarded to each of the SMSCs, and each SMSC again attempts to forward the short message to the subscriber.

Abstract

L'invention concerne, dans un mode de réalisation, un système comprenant un réseau cellulaire, un réseau téléphonique public commuté (RTPC) et un réseau téléphonique mobile IP (MIPTN). Le réseau cellulaire et le MIPTN comportent tous les deux une fonction locale et une ou plusieurs fonctions visitées. Les abonnés MIPTN peuvent naviguer à l'intérieur du MIPTN. Une fonction passerelle crée également une interface entre le RTPC et le MIPTN, de façon à permettre une itinérance entre le réseau cellulaire et le MIPTN. Cette fonction passerelle joue un rôle dynamique de transposition entre les adresses cellulaires /RTPC (par exemple en format E.164) et les adresses MIPTN (par exemple, les adresses IP) afin de permettre l'enregistrement et le transfert de communications pour des abonnés en itinérance entre le réseau cellulaire et le MIPTN. Un type semblable de fonction passerelle permet également la délivrance de messages de service de messages courts SMS sur la totalité du MIPTN.
