20、748495051525354555657585960660 -1 WIN PROCEDURESPART 6601 WIN PROCEDURESSeveral of the following signaling procedures support Wireless Intelligent Network (WIN)capabilities. WIN capabilities are unlike many other wireless network capabilities in that specificservice logic processing procedures for W
21、IN are not defined in this Standard.Basic Call Processing procedures (Part 630) support WIN capabilities related to registration, callorigination, call termination, call disconnection and call recovery.Intersystem Signaling procedures (Part 640) support WIN capabilities related to:- trigger detectio
22、n- service logic invocation- specialized resource connection, disconnection, and usage- service data search and modificationThere are no feature procedures (Part 651) described for WIN because WIN capabilities are servicefeature independent (i.e., they may be used by the service creator to implement
23、 any end user servicefeature).In addition to the specific procedures described in this part of the Standard, the functional entity calland service logic processing models provide a tool used by WIN architects to model a call and tounderstand and describe the distribution of functions between functio
24、nal entities and functionalentity relationships. WIN call and service logic processing encompasses call and connectionprocessing in the Service Switching Function (SSF)/Call Control Function (CCF), service logicexecution in the Service Control Function (SCF) which may include SCF-to-SCF interactions
25、 fordistributed service logic, and the use of supporting resources in the Specialized Resource Function(SRF) and supporting data in the Service Data Function (SDF).TIA-41.660-ECall Modeling for WIN1234567891011121314151617181920212223242526272829303132333435363738394041424344454647484950515253545556
26、57585960660 -21.1 Call Modeling for WINMobile Switching Center (MSC) call modeling for WIN is described by Parts in the 7XX Series,“Wireless Radiotelecommunications Intersystem Operations: Distributed Functional Plane.” Callmodeling provides a high-level service, vendor, and implementation independe
27、nt abstraction ofWIN call and connection processing in the SSF and CCF. This abstraction provides an observableview of SSF/CCF activities and resources to the SCF, enabling the SCF to interact with the SSF inthe course of executing service logic.To provide an observable view of the SSF/CCF to the SC
28、F, and to enable the SCF to interact withthe SSF, call modeling for WIN provides the following:- a foundation based on the existing base of evolvable network technology;- single-ended view of SSF/CCF call processing in terms of both Originating andTerminating Basic Call State Models (BCSMs);- a fram
29、ework for defining trigger requirements in the BCSMs to invoke WIN service logicand to report call processing events to WIN service logic in terms of Detection Points(DPs), which can be used in combinations by the implementor to provide network services;- a framework for ensuring correct sequencing
30、of functions within an SSF/CCF in terms ofBCSM Points in Call (PICs) and transitions;- rules of representing and handling service logic instance interactions; and- a framework for defining the information flows (relationships) between an SSF and anSCF.Examples of call and connection processing funct
31、ions accessible to the SCF from the SSF/CCF asreflected in the WIN information flows (intersystem signaling operations) include functions to:- influence the flow of call processing (e.g., rerouting a call, clearing a call or providing serialcalling);- access and change information related to call pr
32、ocessing (e.g., address translation, routinginformation);- manipulate the connectivity of the call (e.g., forwarding and other capabilities for furtherstudy);- monitor for events related to call processing and connectivity manipulation (e.g., noanswer, busy, disconnect).TIA-41.660-E12345678910111213

34、ded to support this service logic execution, as well as an abstraction of SRF and SDFactivities and resources accessible to the SCF.To provide an abstraction of SCF activities and resources, as well as SRF and SDF activities andresources accessible to the SCF, modeling of service logic processing fo
35、r WIN provides thefollowing:- a high-level service, vendor and implementation independent abstraction of service logicprocessing in the SCF, specialized resources in the SRF and service data in the SDF;- a characterization of the capabilities of an SRF and SDF made available to an SCF;- a framework
36、for defining the information flows (relationships) between an SRF and an SCFand between an SDF and an SCF.Note that the SRF, SCF, and SDF modeling only provides high-level modeling of necessaryfunctionality, but makes no recommendations on specific mechanisms to implement thisfunctionality (e.g., no
37、 recommendations on service logic invocation, management of service logicinstance interactions, reservation and allocation of specialized resources, data architecture andaccess to data). Also, note that the modeling primarily addresses the functionality for normal callprocessing scenarios.Examples o
38、f specialized resource functions accessible to the SCF from the SRF as reflected in therelated WIN information flows include functions to:- send information to users participating in a call (e.g., prompts for information,announcements);- receive information from users participating in a call (e.g.,
39、authorization codes);- modify user information (e.g., text to speech synthesis, protocol conversion); and- provide specialized connection resources (e.g., audio conference bridge, informationdistribution bridge). Examples of service data processing functions accessible to the SCF from the SDF as ref
40、lected inthe related WIN information flows include functions to:- access service information (e.g., subscription data parameters); and- update service information (e.g., sum of charging).THE TELECOMMUNICATIONS INDUSTRY ASSOCIATION TIA represents the global information and communications technology (
