  • the method may also include sending an indication that the required QOS cannot be provided from the packet-switched network to the mobile network, upon determining that the required
  • the indication may also provide the QOS level that is available.
  • the present invention is a method of providing a required quality of service (QOS) level for a call that is originated in a mobile radio telecommunications network and is routed through a packet-switched network when the mobile switching center (MSC) is connected to a plurality of packet-switched networks.
  • the MSC may simultaneously send an indication of the required QOS from the mobile network to each of the plurality of packet-switched networks.
  • Each packet- switched network determines whether it can provide the required QOS, and sends an indication of whether the required QOS can be provided to the MSC.
  • the MS C may sequentially query the packet-switching networks to determine the QOS available.
  • the present invention is a method of accessing a packet- switched network from a mobile radio telecommunications network having an MSC.
  • the method includes the steps of establishing a plurality of signaling connections between the MSC and a plurality of packet-switched networks, and sending a plurality of access messages from the MSC to the plurality of packet-switched networks.

  • FIG. 1 is a simplified block diagram of a network architecture 1 in which the method of the present invention may be practiced in order to provide a required QOS level for a call originated by a mobile station (MS) 2 which is routed through a VOIP network 3.
  • An MSC 4 utilizes Integrated Services User Part (ISUP) messages to set up a connection 5 with a VOIP Gateway (GW) 6.
  • the destination in the VOIP network is a Terminating Gateway (T-GW) 7.
  • a Gate Keeper (GK) 8 maintains an overall status of the VOIP network regarding latency delays, congestion, etc. Calls which are successfully routed through the VOIP network are sent from the T-GW to a Service Switching Point (SSP) 9 for further routing.
  • FIG. 2 is a sequence diagram illustrating the flow of messages between the
  • An ISUP Initial Address Message (IAM) 11 is sent from the MSC to the Gateway with a newly defined QOS Required parameter 12.
  • the QOS Required parameter specifies performance levels which impact QOS such as, for example, the number of router hops allowed in the VOIP network 3, the bandwidth required, and/or the latency in terms of time allowed for packet transport to the T-GW 7.
  • the Gateway may confer with the Gate Keeper 8 utilizing procedures outlined in H.323 to determine whether it is possible to provide the QOS required. This determination is based on the MDN provided in the IAM message which determines the T-GW at the destination end of the network.
  • the Gateway sends an Admission Request (ARQ) message 13 to the Gate Keeper which makes its QOS determination and returns an Admission Confirmation (ACF) message 14 to the Gateway.
  • ARQ Admission Request
  • ACF Admission Confirmation
  • Table 1 illustrates the use of the QOS Required parameter in the ISUP Initial Address Message (IAM).
  • the Gateway 6 sends an ISUP Address Complete Message (ACM) 15 to the MSC 4 and includes a QOS Available parameter 16 that indicates the QOS level that the VOIP network can provide, and thus indicates whether the VOIP network can satisfy the demanded quality of service (QOS)
  • ACM ISUP Address Complete Message
  • the call is routed to the Gateway, through the VOIP network 3, and to the SSP 9.
  • Table 2 illustrates the use of the QOS Available parameter in the ISUP Address Complete Message (ACM).
  • Some applications require more bandwidth in the VOIP network than others, and at any one time, several applications may compete for available bandwidth.
  • the mobile call must have sufficient bandwidth allocated to it to ensure the required QOS is provided. If the mobile call also has data or graphics associated with it, the VOIP network may indicate an available bandwidth that is sufficient for voice only.
  • the MSC may then attempt to route the call through another VOIP network or the PSTN, or may provide an announcement to the calling subscriber informing him/her that only resources for voice calls are available.
  • FIG. 3 is a simplified block diagram of the preferred embodiment of an architecture 20 for routing a MS-originated call through a VOIP network and for providing a required QOS level for the call.

  • FIG. 4 is a sequence diagram illustrating the flow of messages for routing a MS-originated call through a VOIP network when the MSC 4 is connected to more than one VOIP Gateway and to one or more VOIP networks.
  • the MSC is illustrated as being connected to Gateway- 1 A (22), Gateway-2 A (24), and a plurality of other Gateways including Gateway-N (33).
  • the MSC may send ISUP messages to many gateways in one or more VOIP networks. The call, therefore, is more likely to be successfully set up with the required QOS.
  • the MSC 4 sends a plurality of IAM messages 34-36, one to each of the connected Gateways.
  • the IAM messages each include the QOS Required parameter
  • the MSC may have a preferred Gateway which is always tried first.
  • each of the Gateways may then confer with a Gate Keeper associated with the VOIP network to which the Gateway is connected to determine the level of QOS which can be provided.
  • each Gateway returns an ACM message to the MSC 4 and includes the QOS Available parameter 16.
  • the QOS Available parameter indicates the QOS level that the VOIP network can provide, and thus indicates whether the VOIP network can satisfy the demanded quality of service (QOS Required).
  • the call may then be routed in one of several alternative ways.
  • the MSC may route the call to the first Gateway that sends an ACM message with a QOS Available which meets or exceeds the QOS Required.
  • the MSC may collect responses for a predetermined time period and then route the call to the Gateway which reported the best QOS Available.
  • FIG. 5 is a sequence diagram illustrating the flow of messages for routing a
  • the MSC 4 sends a plurality of IAM messages 41 -43, one to each of the connected Gateways, and includes the QOS Required parameter in each message. Each VOIP network then determines whether or not it can provide the required QOS. Each Gateway then returns an ACM message to the MSC 4 and includes the QOS Available parameter. In the example illustrated in FIG. 5, none of the associated VOIP networks can provide the required QOS. Therefore, the MSC may, at 48, route the call to a node in an alternative network such as the Public Switched Telephone Network (PSTN) instead of a VOIP network.
  • PSTN Public Switched Telephone Network
  • the subscriber may pay a higher rate since the call is routed through the PSTN.
  • An appropriate rate must be determined, and the operator may provide the call at the VOIP network rate since the subscriber attempted the call through the VOIP network, but the VOIP network could not provide the service.
