- ATM Asynchronous Transfer Mode
- ATM is a packet switching and multiplexing technique specifically designed to handle both voice users and packet data users in a single physical channel.
- ATM supports bidirectional transfer of data packets of fixed length between two end points, while preserving the order of transmission. More importantly, through use of B-ISDN call controls and ATM technology, disparate services having different characteristics are handled in a uniform way.
- every bearer is characterized by a set of parameters such as bandwidth, delay, delay variation, cell loss ratio, etc., all of which may be found in ITU-T Recommendation Q.2931.
- an object of the present invention to provide an improved system and method for the uniform handling of disparate services having different characteristics in a wireless environment.
- the present invention is directed to an improved system and method for wireless data transmission across a variety of telecommunications services operating under a variety of standards.
- the system and method operate by separating the traditional call control into service-specific call control .and radio-specific call control in mobile access, providing a generic call control mechanism offering uniformity in communications and allowing a separate connection control mechanism to handle the physical and virtual channel connections.
- FIGURE 1 is a schematic diagram of the component configuration of the system and method of the present invention, illustrating the control plane entities for the separation of traditional call control into service-specific call control and radio-specific call control;
- FIGURE 2 is a schematic diagram of the user plane bearer connectors between the components of FIGURE 1.
- FIGURE 1 there is shown a block diagram illustrating the components and configuration of a system according to the present invention.
- a mobile station (MS) 10 is in radio communication with a local Mobile Services Switching Center (MSC) 12.
- MS 10 may communicate with MSC 12 via a base station (not shown), as is understood by those skilled in the art.
- MSC 12 is connected to other networks via appropriate interfaces.
- this network is an ATM- based B-ISDN 14 network
- the interface preferably fulfills the B-ISDN NNI (Network Node Interface) specification as specified by the standardization organizations.
- This ATM-based B-ISDN network has a number of ATM end stations connected thereto. These ATM end stations can be, for example, gateways to other networks, and are generally referred to herein as Service Nodes 16. For instance, Service Node 16 in FIGURE 1 can act as a gateway between a Transmission Control -5-
- TCP/IP Protocol/Internet Protocol
- a Service Call Control entity in a mobile phone designated herein by the reference identifier implements a standard call control functionality such as found in B-ISDN terminals.
- the second, a Wireless network-specific Call Control in a mobile phone implements the requisite radio access call control functionality, £ *,, service negotiation, etc., which are radio access technology dependent.
- CC of the MS 10 is divided into a high-level command entity (SCC MS ), utilizing standard call control protocols and functions, and a lower-level, application-specific command entity (WCC MS ) capable of implementing the high-level command on the particular radio access technology and characteristics utilized by that MS 10, e_g-, for GSM, CDPD, etc.
- SCC MS high-level command entity
- WCC MS application-specific command entity
- MSC 12 As in MS 10, the control within the MSC 12 pursuant to the present invention is also divided into an SCC MSC , implementing the aforementioned standard call control functionality, e-g-, B-ISDN, and a WCC MSC , implementing the aforedescribed technology-dependent radio access call control functionality.
- MSC 12 also includes a Wireless Network Resource Handler (WNRH) therein for handling the particular radio resources and access network transport resources available.
- WNRH Wireless Network Resource Handler
- MSC 12 further includes a Fixed-side Call Control (FCC) for handling call control functionality towards at least one service node in a fixed or control switched network, as will be described in more detail hereinafter.
- FCC Fixed-side Call Control
- WCC MSC connect, in MS 10 there is no direct connection or relationship between the SCC MS and WCC MS .
- FCC -6- implements the similar call control functionality as is found in the network to which the MSC connects to. If MSC 12 connects to several types of networks, B&, to B-ISDN and N-ISDN, then the MSC 12 must be equipped with FCC functionality capable of interacting with the call control functionality in both networks, L&., in the MSC 12 there must be .an FCC for both networks.
- the MSC 12 also contains an InterWorking Functions (IWF) module which implements the bearer services offered by the mobile network.
- IWF InterWorking Functions
- FIGURE 2 there is shown the aforementioned IWF within the MSC 12, providing an end-to-end bearer connection from the MS 10 to the SN 16.
- FIGURE 1 illustrates the control pl.ane entities being used in the communication between the MS 10 and Service Node 16
- FIGURE 2 illustrates the user plane bearer connections therebetween.
- the inter- working functions convert the user data from a format used over the radio interface to a format used in standard fixed networks.
- the FCC and fixed network call control entities set up and control the fixed network bearer connection. It should be understood that the end-to-end bearer connection, made up of the concatenation of the radio bearer connection and the fixed network connection, is, in turn, controlled and set up by the SCC protocol.
- the SCC MS forwards a conventional, high-level set-up message to the SCC MSC in the MSC 12.
- the transmitted set-up message conforms to a known protocol, e ⁇ ., using the standard B-ISDN User-Network Interface (UNI) layer 3 specification for basic call/connection control, L ⁇ -, using ITU-T Recommendation Q.2931. -7-
- the SCC MSC Upon reception, the SCC MSC examines the informational elements of the set-up message. The parameters related to the requested bearer service are then forwarded to the WCC MSC . These radio interface connection parameters include, £ *-, bandwidth related parameters, quality of service in terms of delay and delay variation, etc. It should also be understood that optional informational elements or other modifications may be made to the aforementioned standard Q.2931 message protocol to better adapt the Q.2931 protocol to the wireless environment.
- the WCC MSC Upon reception, the WCC MSC examines the message parameters forwarded by the SCC MSC and translates the message parameters to conform to the particular radio access technology characteristics used in transmission. It should, of course, be understood that the aforementioned translation process within the WCC MSC , using the aforedescribed IWF module illustrated in FIGURE 2, produces both different parameters and connections for different telecommunications systems, & , GSM and wideband Code Division Multiple
- CDMA Code Division Multiple Access
- the WNRH determines whether or not a new user data connection to the particular cell (of the MS 10) is possible and forwards an acceptance or rejection signal to the WCC MSC . If the data connection can be made and the communication is accepted, the WCC MSC requests the WNRH to reserve the resources necessary for the connection. It should be understood that the WNRH may then allocate the requisite resources itself.
- the WCC MSC Upon connection acceptance, the WCC MSC sends a set-up message to the WCC MS , including the requisite radio access technology dependent parameters in order to set up the requested bearer(s).
- the set-up request can be rejected to the WCC MS , e ⁇ , on the basis of lacking resources in the mobile station (Le., the MS 10 cannot handle the requested bearer).
- the WCC MS sends an acknowledgment signal to the WCC MSC .
- the WCC MSC Upon receipt of the aforesaid acknowledgment signal, the WCC MSC forwards an acknowledgment signal to the SCC MSC in MSC 12.
- the SCC MSC while initially contacting the WCC MSC and forwarding the aforedescribed service parameters, may also forward a message to the FCC.
- the parameters in the FCC message from the SCC MSC are preferably a subset of those of the original set-up request from the SCC MS where the requested connection is to an ATM network, such as the one illustrated in FIGURE 1 with the reference numeral 14. It should also be understood, however, that the parameters in the
- SCC MS -SCC MSC message exchange describe end-to-end service, and in an ATM network the parameters are preferably the same. In the case of an N-ISDN network, however, a parameter translation must be done.
- the FCC upon receipt of the aforedescribed FCC message parameters, then forwards a message to the aforementioned ATM network 14 for a connection to the call control functionality in particular Service Node 16 indicated by the SCC MS in the original set-up request.
- the FCC further reserves resources for the connection between the MSC 12 and the ATM network 14, £., the exchange terminal, the interface between which, as discussed, is Network Node Interface-type.
- the FCC After the FCC receives a message from the ATM network 14 that the resources to the particular Service Node 16 are reserved, the FCC forwards a message to the SCC MSC to that effect, and the SCC MSC , in turn, notifies the SCC MS that the other end of the connection is ringing.
- the SCC MSC forwards a connect message to the SCC MS .
- the SCC MS upon receipt of the connect message, sends an acknowledgment message back to the SCC MSC , which makes a through connection from the MS 10 to the particular Service Node 16 in the mobile network. It should be understood that the aforesaid through connection includes the connection of the IWF to the MS 10 via various devices.
- SCC MSC then orders the FCC to send a connect-acknowledgment message to the -9-
- ATM network 14 which finalizes the through connection to the particular Service Node 16.
- the system .and method of the present invention preferably provides a B-ISDN-like mechanism for mobile access. For example, in the case of a packet data connection to a Transmission Control Protocol/Internet
- TCP/IP Transmission Control Protocol
- PLMN Public Land Mobile Network
- the introduction of B-ISDN-like call control procedures and the separation of call and connection control in the mobile access permits the integration of call control procedures of all services, including packet data services, creating a generic call control mechanism and uniform call control message exchange over the air interface for all services.
- the connection control is handled separately inside the PLMN through virtual connections.
- one embodiment of the present invention directed to the creation of a virtual connection to a gateway between an ATM-based PLMN and the Internet is described, e ⁇ ., in connection with the use of IETF RFC 1755 (ATM signaling support for Internet Protocol over ATM) for transferring Internet Protocol (IP) datagrams between the MS 10 and an Internet gateway, other embodiments should be considered within the scope of the present invention also.
- the network to which the MSC 12 (or the PLMN) -10- connects may not be an ATM-based B-ISDN network and instead may be an N-ISDN network or other like network.
