30、fied Modelling Language 4 What is the meta-protocol? 4.1 Introduction The meta-protocol serves as the platform for candidate protocols to map to and in which the mapping identifies exactly how the requirements are met. The description of the meta-protocol consists of 2 parts: requirements of the ser

31、vice or service capability; and functional behaviour of the service or service capability. 4.2 Content of the requirements section The requirements section of the meta-protocol for any service (or service capability) is an overall description from the users standpoint and consists of a definition an

32、d description of the service (or service capability) in prose, followed by an overall summary of the dynamic behaviour in either an SDL process diagram, or an UML activity diagram. 4.2.1 Definition This clause provides a short description of the service (or service capability) in terms of the percep

33、tions of the user receiving the service (or service capability) and any other users involved in the service (or service capability). 4.2.2 Description This clause expands on the definition and summarizes the operation of the service (or service capability) in a generic form which does not constrain

34、terminal or network design. It is intended to allow an understanding of the service (or service capability) without regard to implementation. It also includes any specific terminology used within the prose definition and description, and any qualifications. For basic services this clause details the

35、 applications which could utilize the service whilst for supplementary services this clause details their applicability to particular telecommunication services. 4.2.3 Procedures The overall operation of the service (or service capability) in its various states is described in this clause. These pro

36、cedures relate to all actions between the user(s) and the network during the period that the service (or service capability) is available. ETSI ETSI TS 101 882-1 V4.1.1 (2003-09) 8 4.2.3.1 Provision/withdrawal This clause describes the means by which the service (or service capability) is made avail

37、able by the service provider, e.g. it may be generally available to all customers, or only be available to those customers who have made a prior arrangement. 4.2.3.2 Normal procedures The clauses under this heading describe the normal procedures for activation, deactivation, registration, invocation

38、 and operation for the service (or service capability) as appropriate. This clause describes only the successful outcome of each procedure, and the procedures which are executed as a result of such successful outcomes. The procedures are described in a time-based sequence of events. They describe th

39、e interactions of the users involved in the service (or service capability) with the service provider and with each other which lead to, and are elements of, the successful operation of the service (or service capability). 4.2.3.2.1 Activation/deactivation/registration The procedures for activation,

40、 which is the operation of bringing the service into the “ready for invocation“ state, and deactivation, which is the complementary action, are described in this clause. For some services (or service capability) there may be a specific user procedure to allow activation and deactivation as necessary

41、, whilst for others the service (or service capability) is permanently activated on provision and thus no procedure is provided. Registration describes the procedures by which any specific information, necessary for the successful operation of the supplementary service, is given to the network. The

42、need to register information with the network, e.g. a forwarding number, only applies to certain services (or service capabilities). 4.2.3.2.2 Invocation and operation This clause describes the procedures for invocation, which is the action and conditions under which the service (or service capabili

43、ty) is brought into operation; in the case of some services (or service capabilities) this may only be on a particular call. It should be noted that although a service (or service capability) may be activated, it may not necessarily be invoked on all calls. (Invocation may take place either subseque

44、nt to or simultaneously with activation.) In the case of basic services this clause shall describe the events, perceived at the service access point, during the establishment, information transfer and clearing phases. Operation is the procedure which occurs once a service (or service capability) has

45、 been invoked. This description gives details of the significant actions of the network, treated in principle as a single entity, and the perception of the users involved in the service (or service capability). It includes details of the information exchanged between the network and relevant users a

46、nd the indications given to each user, by the network, concerning the states of the service (or service capability). 4.2.3.2.3 Interrogation/editing Interrogation is the facility which enables a served user to determine, from the service provider, the current status of a particular service. Whether

47、this facility is provided for the service (or service capability) being described, and if so, the procedures that accompany it, are detailed in this clause. 4.2.3.3 Exceptional procedures The clauses under this heading describe the exceptional procedures which result in an unsuccessful outcome of th

48、e service (or service capability). Included within this description are the details for such situations as invalid user action and the handling of certain network and interface conditions. For the case of basic services this includes the handling of such network conditions as congestion. ETSI ETSI T

49、S 101 882-1 V4.1.1 (2003-09) 9 4.2.4 Interaction with other services and service capabilities This clause shall describe all interactions of the service or service capability with other services or service capabilities insofar as they have been identified. For example, for some service or service capability pairs there is no interaction as the two are not permitted to be both in operation at the same time. For other pairs, one or both services (or service capabilities) may be modified whilst the pair are in operation simultaneously. 4.2.5 Conte
