23、nswering Point (PSAP) to request an emergency response from the appropriate agency (e.g., fire, police, ambulance, poison control center, or suicide prevention center)1. The PSAP shall be the PSAP appropriate to the calling subscribers current location. A 9-1-1 call shall bypass any authorization re
24、strictions or call origination restrictions features (e.g., Subscriber PIN Access (SPINA), Subscriber PIN Intercept (SPINI) features). The call shall automatically invoke Priority Access and Channel Assignment (PACA), and the call shall be given higher priority than normal calls. Once the call is an
25、swered, the subscriber shall be able to communicate the type of emergency over a normal voice connection with the PSAP. (Encryption may be used over the air interface, but it must be removed on the connection to the PSAP.) A 9-1-1 call does impact a subscribers ability to originate or receive calls
26、while the 9-1-1 call is in progress. Flash privileges (features controlled by activating the SEND key, such as, Call Waiting, Three-Way Calling, Conference Calling, and Call Transfer) are suspended during the 9-1-1 call, except to reconnect a call placed on hold to place the 9-1-1 call. When the 9-1
27、-1 call is released, the subscribers normal calling capabilities are restored. Release occurs when either the subscriber or PSAP disconnects. Special release controls may apply, as described in Emergency Services Reconnect (9-1-1RC). Applicability to Telecommunications Services 9-1-1 is applicable t
28、o voice and Teletype Devices for the Deaf (TDD) telecommunication services. 1.1 Normal Procedures with Successful Outcome Authorization 9-1-1 shall be generally available. Deauthorization 9-1-1 shall not be withdrawn. Registration 9-1-1 has no registration. 1The services available may vary between c
29、ommunities. TIA-664.529-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 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 Emergency Services (9-1-1) 529-2 Deregistration 9-1-1 has no deregistration. Activation 9-1-1 has no ac
30、tivation. Deactivation 9-1-1 has no deactivation. Invocation 9-1-1 is invoked by the subscriber dialing 9 -1 -1 -SEND 2. The sequence may be dialed while the MS is idle, while the MS is engaged in a call, or while the MS has a call on hold. If no air interface channels are available when 9-1-1 is in
31、voked, the request may be delayed by automatically invoking Priority Access and Channel Assignment (PACA) for a level appropriate for a subscriber dialing 9-1-1. Normal Operation with Successful Outcome When 9-1-1 is invoked, the call is routed to the appropriate Public Safety Answering Point (PSAP)
32、. Routing decisions are based upon the current location of the invoking MS and possibly other factors, such as, the availability of a selective router, PSAP, or interconnecting trunks. If 9-1-1 is invoked from within a call, the other party is placed on hold in a similar fashion to a subscriber atte
33、mpt to invoke Three-Way Call (3WC) or Conference Call (CC). Once 9-1-1 is invoked, the subscribers normal flash privileges are suspended. If a call is on hold to make the 9-1-1 call, the held call can be joined to the 9-1-1 call in a Three-Way Call or Conference Call by the subscriber activating the
34、 SEND key. Once the call is joined, subsequent flash requests shall be ignored, until the call is released. 2Additionally 9-1-1 should be permissively invoked by the subscriber dialing * -9 -1 -1 -SEND .

PACA and air segment usage. See DMH for the specific information to
36、be included for each element. 1.2 Exception Procedures or Unsuccessful Outcome Registration None identified. Deregistration None identified. Activation None identified. Deactivation None identified. Invocation None identified. Exceptions While Roaming None identified. Exceptions During Intersystem H
37、andoff None identified. 1.3 Alternative Procedures None identified.

38、ns with Other Wireless Services Asynchronous Data Service (ADS) None identified, providing the PSAP and the emergency services network have the appropriate equipment. Call Delivery (CD) None identified. Call ForwardingBusy (CFB) Calls from an authorized emergency service bureau should not be forward
39、ed. The network may not be capable of identifying the call as originating from an emergency service bureau and normal call forwarding may be provided. Call ForwardingDefault (CFD) Calls from an authorized emergency service bureau should not be forwarded. The network may not be capable of identifying
40、 the call as originating from an emergency service bureau and normal call forwarding may be provided. Call ForwardingNo Answer (CFNA) Calls from an authorized emergency service bureau should not be forwarded. The network may not be capable of identifying the call as originating from an emergency ser
41、vice bureau and normal call forwarding may be provided. Call ForwardingUnconditional (CFU) Calls from an authorized emergency service bureau should not be forwarded. The network may not be capable of identifying the call as originating from an emergency service bureau and normal call forwarding may
42、be provided. Call Transfer (CT) If a subscriber with CT invokes 9-1-1 during a call or with a call on hold (thereby seemingly invoking CT), transfer shall not take place if the controlling subscriber disconnects. Also, a flash (an activation of the SEND key) while communicating with a PSAP is used t
43、o bridge the held party into the conversation rather than to disconnect the PSAP. If 9-1-1 is invoked while idle, flash requests and attempts to a third number are ignored. Call Waiting (CW) CW is not possible once 9-1-1 has been invoked. TIA-664.529-B 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

Calling Name Presentation (CNAP) None identified.
45、Calling Number Identification Presentation (CNIP) In cases where a calling subscriber has an arrangement that presentation of their CNI is marked presentation restricted, the serving MSC should deliver all available CNI information (including the presentation restricted indication) to the authorized
46、 emergency service bureaus. Calling Number Identification Restriction (CNIR) In cases where a calling subscriber has an arrangement that presentation of his or her CNI is marked presentation restricted, the serving MSC should deliver all available CNI information (including the presentation restrict
47、ed indication) to the authorized PSAPs. Conference Calling (CC) If a subscriber with CC invoked invokes 9-1-1 for a call leg, or if a subscriber invokes the 9-1-1 call with a CC invocation feature code, the 9-1-1 call is allowed to proceed. A subsequent flash (an activation of the SEND key) while co
48、mmunicating with a PSAP is used to bridge the held party(-ies) into the conversation. No additional parties may be added to the conference call. The PSAP cannot be dropped with the Drop Last Party feature code. Data Privacy (DP) None identified, providing the PSAP and the emergency services network
49、have the appropriate equipment. Do Not Disturb (DND) Emergency Services takes precedence over DND. That is, a call from an authorized emergency service bureau should be able to override a subscribers DND activation. Emergency Services (9-1-1) Not applicable. Flexible Alerting (FA) None identified.
