36、Application Server CS Circuit SwitchedCN Core Network FA Flexible AlertingIP Internet Protocol IM IP MultimediaMMTEL Multimedia Telephony 4 Flexible Alerting (FA) 4.1 Introduction Flexible Alerting (FA) causes a call to a Pilot Identity to branch the call into several legs to alert several terminati
37、on addresses (group members) simultaneously. Additional calls may be delivered to the FA Pilot Identity at any time. The first leg to be answered is connected to the calling party. The other call legs are abandoned. The members of an FA group are described by a list of termination addresses. 4.2 Des
38、cription 4.2.1 General description FA may be used for either a single user or multiple users. The difference between the two is in determining when the FA group is busy. In the single user case, the group is considered to be busy when one of the members is considered to be busy. In the multiple user
39、 case, the group is considered to be busy when all of the accessible members are considered to be busy. A member is considered to be busy when it cannot accept the presentation of another call. The FA pilot identity may have features to manage incoming calls (e.g., Incoming Communications Barring).
40、These features should take precedence over the corresponding features of individual members as described in subclause 4.6. If an FA pilot identity is an FA member Identity, the FA member loses his or her individual incoming call features. In this case, the FA members incoming call features are super
41、seded by the incoming call features of the FA pilot identity. If an FA pilot identity is not an FA member Identity, the features of the FA pilot identity may be changed only through user or service provider configuration. FA does not affect the ability of an FA member to originate calls. FA may affe
42、ct the ability of an FA member to receive calls. If an FA member has only a single identity that is the same as the FA pilot identity, the FA member may not receive calls except through the FA pilot identity. If an FA member has an identity different than the FA pilot identity, the FA member may rec
43、eive calls as an individual as well as calls through the FA pilot identity. Such an FA member may use revertive calling (i.e., a call to itself) for other purposes, such as retrieval of voice mail. ETSI ETSI TS 124 239 V14.0.0 (2017-03)83GPP TS 24.239 version 14.0.0 Release 144.3 Operational require
44、ments 4.3.1 Provision/withdrawal The FA service may be provided after prior arrangement with the service provider. The establishment of the initial constituency (membership) of the FA group, along with additions to or subtractions from the set of group members, is performed by the service provider.
45、The FA service may be withdrawn at the subscribers request or for administrative reasons. Withdrawal of the FA service means dissolution of the FA group and results in calls to the Pilot Identity being treated as calls to a vacant identity. Withdrawal of the FA service is performed by the service pr
46、ovider. As determined by service provider provisioning, the FA group may have the following subscription options, as summarized in table 4.3.1-1. Table 4.3.1-1: FA group subscription options Subscription option values Values Type - Single User. The FA group is considered to be busy when any member o
47、f the group is considered to be busy. - Multiple Users. The FA group is considered to be busy when all accessible members of the group are considered to be busy. As determined by service provider provisioning, the FA member may have the following subscription options, as summarized in table 4.3.1-2.
48、 Table 4.3.1-2: FA member subscription options Subscription option values Values Membership - Demand. An FA member is authorized to activate or deactivate his or her membership in the FA group(s). - Permanent. An FA member is always a member of his or her registered FA group(s). If an FA group is of

The FA member status options are summarized in table 4.3.1-3. Table 4.3.1-3: FA member status options Subscription option values Values Status - Active.
