23、52 53 54 55 56 57 58 59 60 512-1 Flexible Alerting (FA) 1 Flexible Alerting (FA) Flexible Alerting (FA) causes a call to a Pilot Directory Number to branch the call into several legs to alert several termination addresses simultaneously. The mobile telephones in the group may be alerted using distin
24、ctive alerting. Additional calls may be delivered to the FA Pilot Directory Number 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. Each termination address may
25、 either be a Directory Number or a MIN that uniquely identifies a mobile station. This allows MSs served by the same Home Location Register (HLR) as the FA pilot DN, MSs served by other HLRs (especially for serving multi-NAM phones of multiple service providers) and landline telephone numbers to be
26、included1. 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 case, the group is cons
27、idered 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 busy condition of landline telephones cannot always be accurately determined. The FA Pilot Directory Number may have features
28、to manage incoming calls. These features should take precedence over the corresponding features of individual members, however, these interactions, when occurring at the Home Location Register (HLR), are beyond the scope of this Standard. If an FA Pilot Directory Number is an FA member Directory Num
29、ber, the FA member loses his or her individual incoming call features. The FA members incoming call features are superseded by the incoming call features of the FA Pilot Directory Number. If an FA Pilot Directory Number is not an FA member Directory Number, the features of the FA Pilot Directory Num
30、ber may be changed only through Remote Feature Control or service provider provisioning. FA does not affect the ability of an FA member to originate calls. FA may affect the ability of an FA member to receive calls. If an FA member has only a single Directory Number that is the same as the FA Pilot
31、Directory Number, the FA member may not receive calls except through the FA Pilot Directory Number. If an FA member has a Directory Number different than the FA Pilot Directory Number, the FA member may receive calls as an individual as well as calls through the FA Pilot Directory Number. Such an FA
32、 member may use revertive calling (i.e., a call to oneself) for other features, such as Voice Mail Retrieval. 1Interactions between FA and the features of FA members controlled by different systems are beyond the scope of this Standard Flexible Alerting (FA) 512-2 Applicability to Telecommunications
33、 Services FA is applicable to voice telecommunication services. 1.1 Normal Procedures with Successful Outcome Authorization FA Group Authorization FA may be provided after prearrangement with the service provider. The FA group authorization may have the following subscription options: Table 1: FA Gr
34、oup Subscription Options Subscription Options Values Type Single User. The FA group is considered to be busy when a member of the FA group is considered to be busy. Multiple Users. The FA group is considered to be busy when all accessible members of the FA group are considered to be busy. FA Member
35、Authorization The FA member authorization may have the following subscription options: Table 2: FA Member Subscription Options Subscription Options Values Membership Demand. An FA member is authorized to activate and deactivate his or her membership in an FA group(s). Permanent. An FA member is alwa
36、ys a member of his or her registered FA group(s). Deauthorization FA may be withdrawn at the subscribers request or for administrative reasons. Registration FA Pilot Registration FA may be registered by the service provider defining the FA Pilot Directory Number and the FA members during authorizati
37、on. The FA Pilot Directory Number may be the same as the Mobile Directory Number of a member MS. However, in this case it may not be possible to reach the MS individually TIA-664.512-B 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 4

The telephones in an FA group are described by a list of termination addresses. Each termination address may either be a Directo
39、ry Number or a MIN that uniquely identifies a mobile station. This allows MSs served by the same Home Location Register (HLR) as the FA pilot DN, MSs served by other HLRs (especially for serving multi-NAM phones of multiple service providers) and landline telephone numbers to be included. The distin
40、ctive alerting pitch, cadence or both may also be specified for the FA alerting. FA Member Registration Each FA member may register the pilot number(s) of the default group(s) to which it belongs. This pilot number is used to access the group for the membership activate and deactivate feature codes.
41、 Deregistration FA shall be deregistered upon deauthorization. Individual members of the FA group may be deleted at any time by the service provider. Activation FA shall be activated upon registration. Demand Member Activation of a Subscribers Default FA Group(s) An FA Demand Membership Authorized m
42、ember may activate his or her membership in the members default FA group(s) by specifying the FA membership activation feature code, as in: *FC + SEND . If the activation is accepted, the system shall indicate success with feature confirmation treatment. Demand Member Activation of a Specified FA Gr
43、oup An FA Demand Membership Authorized member may activate his or her membership for a single FA group by specifying the FA membership activation feature code and a specific FA Pilot Directory Number, as in: *FC + FA Pilot Directory Number + SEND . If the activation is accepted, the system shall ind
44、icate success with feature confirmation treatment. Deactivation FA shall be deactivated upon deauthorization. Flexible Alerting (FA) 512-4 Demand Member Deactivation of a Subscribers Default FA Group(s) An FA Demand Membership Authorized member may deactivate his or her membership in the members def
45、ault FA group(s) by specifying the FA membership deactivation feature code, as in: *FC0 + SEND . If the deactivation is accepted, the system shall indicate success with feature confirmation treatment. Demand Member Deactivation of a Specified FA Group An FA Demand Membership Authorized member may de
46、activate his or her membership in a single FA group by specifying the FA membership deactivation feature code and a specific FA Pilot Directory Number, as in: *FC0 + FA Pilot Directory Number + SEND . If the deactivation is accepted, the system shall indicate success with feature confirmation treatm
47、ent. Invocation FA is invoked when there is an incoming call to the FA Pilot Directory Number. FA may be invoked with a revertive call (i.e., the MS with a Directory Number equal to the FA Pilot Directory Number may call itself) to reach the other members of the FA group. Normal Operation with Succe
48、ssful Outcome For an incoming call to the FA Pilot Directory Number, a call delivery or termination is attempted for each member of the FA group simultaneously. All of the attempted legs are controlled by the same system. If a member is a Directory Number alone, a call attempt is made to that Direct
49、ory Number. If any of the termination addresses on the list are known to be not an active member of the FA group, are busy, are reported inactive or are not responding to paging, then no attempt need be made for that member. The individual voice features of the active members of an FA group may also be applied. Features of the FA Pilot Directory Number should apply for the FA group as a whole and take precedence over the features of individual FA members. For a Single User FA group, the group is considered to be busy when one member of the group is considered to be busy. CW may apply
