1. Wireless Local Loop (WLL) 2

3 Wireless Local Loop (WLL) is a feature implementation using a serving system that utilizes a 4 wireless connection to a wireless device, such as a mobile station or a network interface unit to 5 provide local loop service to an end user. WLL permits local loop service for subscriber call 6 origination and for receipt of calls. WLL applies to voice and data services. WLL provides 7 signaling mechanisms between the serving system and the mobile station or the network interface 8 unit. This signaling mechanism permits the exchange of call control information. 9 10 The essential signaling elements of WLL are: 11 • Mobile Station or Network interface unit Device Type specification and request for WLL of 12

the serving system or optional serving system Device Type specification 13 • Mobile Station or Network interface unit Dial Tone or optional Dial Tone of the serving 14

system 15 • Mobile Station or Network interface unit Hook Status enabling WLL call control of the 16

serving system 17 • Serving system Autonomous Message Interval specification and request of the mobile station 18

or the network interface unit or optional network interface unit Autonomous Message Interval 19 specification 20

• Serving system Call Waiting Indicator notification to the mobile station or the network 21 interface unit 22

23 The serving system signaling mechanisms shall be provided to permit WLL. The serving system 24 shall permit specification of Dial Tone and the Autonomous Message Interval. The serving system 25 shall permit WLL based upon receipt of mobile station or network interface unit Device Type or 26 optional serving system Device Type specification. The serving system shall permit call control 27 based upon receipt of mobile station or network interface unit Hook Status. The serving system 28 shall permit Autonomous Message Interval and Call Waiting Indicator notification to the mobile 29 station or to the network interface unit. 30 31 The mobile station or the network interface unit mechanisms shall be provided to permit WLL. 32 The mobile station or network interface unit switches shall be provided to permit specification of 33 Device Type, Dial Tone, Hook Status, and Autonomous Message Interval. The mobile station or 34 the network interface unit shall permit Dial Tone as a call progress tone. The mobile station or the 35 network interface unit shall permit Device Type and Hook Status notification to the serving 36 system. 37 38 Device Type The mobile station or network interface unit shall permit Device Type specification 39 and request for WLL of the serving system. Device Type requests one of either: 40

• Wireless Local Loop terminal with no mobility 41 • Wireless Local Loop terminal with limited mobility 42 • Wireless Local Loop terminal with full mobility 43

44 Dial Tone The mobile station or the network interface unit, or optionally the serving system, shall 45 permit Dial Tone. 46 47 Hook Status The mobile station or the network interface unit shall permit Hook Status enabling 48 WLL call control of the serving system. Hook Status enables WLL call control of the serving 49 system using indications of: 50

• Subscriber Terminal On-Hook 51 • Subscriber Terminal Off-Hook 52 • Subscriber Terminal Immobilized Off-Hook 53


1 Autonomous Message Interval The serving system shall permit Autonomous Message Interval 2 specification and request of the mobile station or the network interface unit. The mobile station or 3 the network interface unit specification of Autonomous Message Interval is optional. The 4 Autonomous Message Interval specification enables Autonomous Message Interval Values of any 5 one of the following: 6 7

• 200 milliseconds 8 • 500 milliseconds 9 • 1000 milliseconds 10 • 1500 milliseconds 11 • 2000 milliseconds 12 • 5000 milliseconds 13 • 10000 milliseconds 14 • 15000 milliseconds 15

16 This is defined in Table 3.7.2.3.2.13-4 in IS-2000-A. 17 18 Call Waiting Indicator The serving system shall permit signaled Flash-with-Call- Waiting 19 Indicator notification of the mobile station or the network interface unit. The mobile station or the 20 network interface unit receipt of Flash-with-Call-Waiting Indicator suppresses network interface 21 unit dial tone when called subscriber flashes hookswitch to receive call-waiting call. 22 23

1 1.2 Function Keys 2 3 Flash (Optional) 4

The FLASH key may be used to transmit a "flash" request analogous to a land line 5 hookswitch flash. Depression of the Flash key may be used to trigger the momentary 6 hookswitch flash indication towards the system. 7

8 Hookswitch (Optional) 9

The NIU resident Hookswitch may be used to transmit a number of indicators to the 10 system. The Hookswitch may be used to transmit an “off-hook”, “on-hook” or 11 “immobilized off-hook” indication. The Hookswitch may also be used to transmit a 12 “flash” request analogous to a land line hookswitch flash. 13

14 Talk (On/Off) (Optional) 15

The Talk (On/Off) key may be used to trigger an "off-hook" indication analogous to a 16 land line telephone going off-hook. The "off-hook" indication may be used to request dial 17 tone or to request allocation of resources necessary to service a call origination attempt. 18 Once a call is complete, the call may be released by subsequent depression of the Talk 19 (On/Off) key used to trigger an "on-hook" indication. 20

21 1.3 Switches 22 23 Device Type (Optional) 24

The Device Type switch allows, either the subscriber, or the actions of the autonomous 25 NIU, to control the service desired of the mobile station and serving system. The Device 26 Type switch may be manually set or autonomously set by the NIU to enable the NIU: 27 Wireless Local Loop without Mobility, Wireless Local Loop with Limited Mobility, 28 Wireless Local Loop with Full Mobility or set for traditional Wireless Service. 29

30 Dial Tone (Optional) 31

The Dial Tone switch allows the subscriber to enable mobile station or NIU provided dial 32 tone analogous to that provided by landline. 33

34 Hook Status (Optional) 35

The Hook Status switch allows either the subscriber, or the actions of the autonomous 36 NIU, to enable the NIU to send a Hook Status Indicator to the serving system. The Hook 37 Status is analogous to land line on-hook, off-hook, or immobilized-off-hook indicators as 38 recognized by the serving system. 39 40 Note: The Hook Status may be sent using Registration, Page Response, Status Response 41 and Flash-with-Information Messages to the serving system. 42

43 Autonomous Message Interval (Optional) 44

The Autonomous Message Interval switch allows, either the subscriber, or the actions of 45 the autonomous NIU, to enable minimal time interval between autonomous NIU message 46 transmissions to the serving system. Useful in throttling of Hook Status messages (on-47 /off-hook and off-/on-hook state transitions) being sent by the NIU to the serving system 48 as is the case for wireless local loop applications. 49 50 Note: The Autonomous Message Interval is only used to throttle the transmission of the 51 Hook Status messages when the NIU is in the idle state and not the conversation state. 52 53 The Autonomous Message Interval values are: 54 55


Value Interval 000 200 milliseconds 001 500 milliseconds 010 1000 milliseconds 011 1500 milliseconds 100 2000 milliseconds 101 5000 milliseconds 110 10000 milliseconds 111 15000 milliseconds

1 This is defined in Table 3.7.2.3.2.13-4 in IS-2000-A. 2

3 1.6 Call Progress Tones 4 5 Dial Tone 6

The MS or NIU may provide a locally generated dial tone, either upon command of the 7 base station or, if optioned to do so locally, using the Dial Tone switch. 8

9 The North American dial tone is defined to be a continuous tone of 350 Hz plus 440 Hz 10 at (-13dBm0/frequency). This definition may be different outside of North America. 11

12 1.13 External Interfaces 13

14 An NIU possesses an RJ-11 external interface and may optionally posses other external 15 interfaces, such as RS-232 or USB. The NIU shall be used for Wireless Local Loop. 16 17 The NIU external interfaces may be used to support ancillary telephone or data devices, 18 such as modems, facsimile machines, pay phones, analog subscriber station equipment, 19 or calling line identification display. A NIU possessing external interfaces should assure 20 adequate signaling or signaling inter-working such that the operator and application 21 requirements are met. 22

23 1.13.1 RJ-11 24 25

An analog subscriber line signaling interface that shall use an industry standard RJ-11 26 connector. The electrical interface shall conform to Part 68 of the FCC regulations for 27 loop start lines.1 This interface shall be resident on the mobile station or network 28 interface unit used to host the wireless local loop application. 29 30 For call originations, the MS must convert from loop signaling to Base Station to Mobile 31 Station radio link (air or Um interface) signaling. 32 33 The MS may not be request a wireless channel until it receives an appropriate number of 34 digits following a loop seizure. DTMF or rotary digit signaling is both acceptable for 35 digit signaling. Call requests made over the external connection should be able to request 36 a particular type of channel. 37

38 For call terminations, the MS must generate ring voltage on the loop start line. The 39 connected device may answer the ringing line by seizing it. An answer from an external 40 device should default to a particular type of channel. 41 42

1See also Bell System PUB 61100 which is being replaced by Bell Communication

Research TA-NPL-000912.


Calls may be disconnected by the external device by releasing the loop. The MS should 1 release the external line when calls are disconnected by the network or when radio 2 contact is lost during a call. 3 4 It should be possible to configure the MS to request a particular type of channel for call 5 originations and call terminations to an external device. This choice should be separate 6 from the normal channel preference of the MS. The appropriate choices are: 7

a) Speech codec voice channel required. 8

b) Speech codec voice channel preferred. 9

c) 4 kHz voice channel required. 10

d) 4 kHz voice channel preferred. 11

While the external interface is in use, the MS handset and DTMF dialing pad should be 12 disconnected from the voice channel. 13 14 If the MS is off-hook or otherwise able to accept a voice call when the external interface 15 is released, the MS handset and DTMF dialing pad should be re-connected to the voice 16 path and the radio circuit should not be released. This is to allow a simple form of In-Call 17 Modification. 18 19 Analog data capabilities of the NIU may be accessed through its RJ-11 interface jack. 20 RJ-11 connectivity data speeds in excess of 14.4 kbps are not currently supported. These 21 higher data speeds will, however, be supported using other interfaces. These capabilities 22 would accommodate services using in-band (within the 300-3000 Hz voice band) tone 23 signaling, such as Frequency Shift Keying. Typical analog data devices connected to the 24 network interface would include facsimile machines, computer modems and 25 TDD/TTY’s. 26 27 Digital data capabilities may be provided by the NIU; these could be accessed through 28 interfaces other than the RJ-11 jack, such as through a V.24 or RS-232 interface. 29 Wireless system data rate capabilities will be determined by the applicable wireless 30 system standard; device data rate requirements will be determined by the applicable data 31 device standards. 32

33 34

1.13.2 RS-232 35 An asynchronous binary data interface between the computer equipment and the network 36 interface unit. 37 38 This interface shall be resident on the network interface unit and shall be implemented 39 using either a DB-9, DB-25, or RJ-45 connector. 40

41 1.13.3 Universal Serial Bus (USB) 42

An interface designed to support a broad range of devices, such as computers, printers, 43 mice, joysticks, modems, scanners and keyboards. This interface shall be resident on the 44 network interface unit and shall be implemented using a USB B connector. Universal 45 Serial Bus is designed to be completely plug-and-play. 46 47 This interface shall be resident on the network interface unit and shall be implemented 48 using a USB B connector. 49

5. Wireless Feature Description: General Background and 11

Assumptions 12

13 3GPP2 proposes the additions of hook actions (off-hook, on-hook, hookswitch flash and immobilized off-14 hook) to the State-Action Matrix (Table 3) to reflect the introduction of Wireless Local Loop feature. 15


Wireless Feature Description: General Background and Assumptions 1 2 3 4.2 Call Model 4 5 6

The following subscriber (and other party) actions are defined: 7

A. Address: A subscriber presses the SEND key with termination address digits. 8

C. Conferee: A conferee requests a disconnect. 9

D. Disconnect: The other party (sometimes a calling party) requests a disconnect. 10

E. End: A subscriber presses the END key. 11

F. Feature: A subscriber enters a Feature Code String followed by the SEND key. 12

G. callinG: The calling party sends one or more DTMF digits. 13

H. Held: The held party requests a disconnect. 14

I. Incoming: An incoming call arrives for a subscriber. 15

K. on-hooK: The calling party goes on-hook. 16

L. FLash-hook: The calling party flashes the hookswitch 17

N. aNswers: The other party answers. 18

O. Off-hook: The calling party goes off-hook. 19

P. Period: A time period expires. 20

S. Send: A subscriber presses the SEND key without digits. 21

SO. Immobilized Off-hook: A subscriber goes off-hook without dialing digits 22 beyond the period set by the permanent signal timer. 23

T. Third: The third party requests a disconnect. 24

U. featUre code: A subscriber enters a Feature Code String, a delimiter digit “#,” 25 and a termination address followed by the SEND key 26

A state transition is described by a two-, three-, or four-part transition identifier (XID) 27 composed of the state number followed by the call party action identifying letter. This 28 may be followed by optional transition qualification codes as: 29

L. aLternate: An alternate procedure transition. 30

X. eXception: An exception procedure transition. 31

For multiple state transitions of the same type, there is a trailing digit to uniquely identify 32 the transition within this Standard. For example: 33

3ALX 1 designates a state transition for: 34

State 3: 2-way. 35

Event A: Address and send. 36


L: Alternative procedure. 1

X: Exception procedure. 2

1: First occurrence of multiple occurrences within this Standard. 3

The following tables summarize the feature interactions in a state-action matrix for the 4 features in this Standard: 5
