    FOREWARD

    xii

    (This foreword is not part of this Standard)1

    These technical requirements form a standard for Over-the-Air Service Provisioning of2

    mobile stations. A mobile station operating in either the analog or the spread spectrum3

    (CDMA) mode conforming with various versions of the CDMA standards, such as4

    TIA/EIA/IS-2000-A, TIA/EIA/IS-2000, TIA/EIA-95-B, TIA/EIA/IS-95-A (inclusive of5

    TSB74), or ANSI J-STD-008 and this standard can be activated over the air in any system6

    conforming with these standards.7

    The scope of this standard covers over-the-air provisioning of mobile station operational8

    parameters. This standard does not address the quality or reliability of Over-the-Air9

    Service Provisioning, nor does it cover equipment performance or measurement10

    procedures.11

    NOTES

    xiii

    1. The following verbal forms are used: Shall and shall not identify requirements to1

    be followed strictly to conform to the standard and from which no deviation is2

    permitted. Should and should not indicate that one of several possibilities is3

    recommended as particularly suitable, without mentioning or excluding others; that4a certain course of action is preferred but not necessarily required; or that (in the5

    negative form) a certain possibility or course of action is discouraged but not6

    prohibited. May and need not indicate a course of action permissible within the7

    limits of the standard. Can and cannot are used for statements of possibility and8

    capability, whether material, physical, or causal.9

    2. Footnotes appear at various points in this specification to elaborate and further10

    clarify items discussed in the body of the specification.11

    3. Unless indicated otherwise, this document presents numbers in decimal form.12

    Binary numbers are distinguished in the text by the use of single quotation marks.13

    In some tables, binary values may appear without single quotation marks if table14

    notation clearly specifies that values are binary. The character x is used to15

    represent a binary bit of unspecified value. For example xxx00010 represents any16

    8-bit binary value such that the least significant five bits equal 00010.17

    Hexadecimal numbers (base 16) are distinguished in the text by use of the form18

    0xhh where hh represents a string of hexadecimal digits. For example, 0x2fa119

    represents a number whose binary value is 0010111110100001 and whose decimal20

    value is 12193. Note that the exact number of bits in the binary representation of a21

    hexadecimal number strictly depends on the implementation requirements for the22

    variable being represented.23

    4. Numeric information is used to describe the operation of the mobile station. The24

    following subscripts are used in this document to clarify the use of the numeric25

    information:26

    s indicates a value stored in a mobile stations temporary memory.27

    r indicates a value received by a mobile station over a forward analog channel28

    or a CDMA Forward Channel.29

    p indicates a value set in a mobile stations permanent security and30

    identification memory.31

    s-p indicates a value stored in a mobile stations semi-permanent security and32

    identification memory.33

    5. The term mobile station is equivalent to the term personal station.34

    6. IMSI_T Parameter Block does not apply for the mobile station conforming with35

    TIA/EIA/IS-95-A (inclusive of TSB74) or ANSI J-STD-008.36

    7. IMSI_M in this document is equivalent to IMSI defined in TIA/EIA/IS-95-A (inclusive37

    of TSB74) or ANSI J-STD-008.38

    2 MESSAGE TRANSPORT PROTOCOL1

    2.1 General2

    OTASP Data Messages (see Sections 3 and 4) can be sent over the analog voice channel or3

    the CDMA Traffic Channel. In either case, the OTASP Data Messages are sent using a4

    Layer 2 protocol that provides reliable delivery and duplicate detection.5

    The delivery of OTASP Data Messages does not require sequential delivery of messages by6

    the Layer 2 protocol because the Over-the-Air Service Provisioning procedures ensure that7

    only one OTASP Data Message is outstanding at any time.8

    During the analog mode of operation, OTASP Data Messages are sent using the analog9

    transport protocol (see 2.2). During the CDMA mode of operation, OTASP Data Messages10

    are sent using the CDMA transport protocol (see 2.3).11

    2.2 Analog Transport Protocol12

    OTASP Data Messages are transmitted over an analog voice channel using the OTASP13

    Transport Message. Signaling on the analog voice channel does not have a Layer 2 protocol14

    defined in [1,6]. Because of the large amount of data transported for Over-the-Air Service15

    Provisioning, this standard defines a Layer 2 protocol to ensure OTASP Data Message16

    integrity. This protocol provides message segmentation, segment acknowledgment, error17

    detection and re-transmission.18

    2.2.1 OTASP Data MessageEncapsulation19

    Each OTASP Data MessageUnit transmitted on an analog voice channel shall consist of an20

    8-bit message length field (MSG_LENGTH), an OTASP Data Message, as defined in 3.5 and21

    4.5, and a 16-bit CRC, in that order (see Figure 2.2.1-1).22

    The MSG_LENGTH field shall be set to the number of octets in the OTASP Data Message1

    plus three.2

    The 16-bit CRC is calculated on the MSG_LENGTH field and the OTASP Data Message bits.3

    The 16-bit CRC shall be computed according to the following procedure using the logic6

    shown in Figure 2.2.1-2:7

    Initially, all shift register elements shall be set to logical one and the switches shall8

    be set in the position A.9

    The register shall be clocked with each OTASP Data Messagebit as an input, most10

    significant bit first.11

    The switches shall be set in the position B, and the register shall be clocked an12

    additional 16 times. The 16 additional output bits shall be the CRC bits.13

    The 16 CRC bits shall be transmitted in the order calculated.14

    Messages(see 2.2.2).20

    2.2.2 OTASP Data MessageSegmentation21

    Each OTASP Data MessageCapsule (see 2.2.1) sent on an analog voice channel shall be22

    segmented and transmitted in one or more OTASP Transport Messages, as defined in23

    2.2.3.4 and 2.2.4.3. Figures 2.2.2-1 and 2.2.2-2 illustrate the segmentation process for the24

    2.2.3 Mobile Station Procedures4

    OTASP Data Messages are sent and received on analog voice channels only when the5

    mobile station is in the Conversation Task (see 2.6.4.4 of [1]). The mobile station shall6

    transmit OTASP Transport Messages in accordance with the procedures in 2.7.2 of [1].7

    Mobile stations implementing the Over-the-Air Service Provisioning feature shall comply8

    with the following requirements in addition to those of 2.6.4.4 of [1].9

    2.2.3.1 OTASP Transport MessageAcknowledgment and Re-transmission10

    When the mobile station sends an OTASP Transport Message, it starts the OTASP11

    acknowledgment timer. The timer is disabled when an OTASP Transport Confirmation12

    Messageis received.13

    After sending an OTASP Transport Message, the mobile station shall not send a new OTASP14

    Transport Message until it has received an OTASP Transport Confirmation Message15

    acknowledging the message that has been sent.16

    If the OTASP acknowledgment timer expires and the OTASP TransportMessage has been17

    sent fewer than three times, the mobile station shall resend the OTASP TransportMessage18

    and reset the OTASP acknowledgment timer to two seconds. If the OTASP acknowledgment19

    timer expires and the OTASP Transport Message has been sent three times, the mobile20

    station shall enter the Release Task (see 2.6.4.5 of [1]).21

    OTASP Data Messages are sent and received on the analog voice channel only when the2

    base station is in the Conversation Task (see 3.6.4.4 of [1]). The base station shall transmit3

    OTASP Transport Messages as specified in 3.7.2 of [1]. Base stations implementing the4

    Over-the-Air Service Provisioning feature should comply with the following requirements in5

    addition to those of 3.6.4.4 of [1].6

    2.2.4.1 Message Transmission7

    While the base station is in the Conversation Task, the following messages can be sent in8

    addition to those listed in 3.6.4.4 of [1]:9

    1. OTASP Transport Message:10

    The base station should construct the OTASP TransportMessage as follows:11

    If the OTASP_DATA field of the OTASP TransportMessage contains an entire12

    OTASP Data MessageCapsule, the base station should set the value of the13

    SEQ_NUM field to 00000 and the value of the B/F field to 11.14

    If the OTASP_DATA field of the OTASP TransportMessage contains the first15

    segment of the segmented OTASP Data MessageCapsule, the base station16

    should set the value of the SEQ_NUM field to 00000 and the value of the B/F17

    field to 10.18

    If the OTASP_DATA field of the OTASP TransportMessage contains a segment19

    other than the first segment of the segmented OTASP Data MessageCapsule, the20

    base station should perform the following:21

    - If the OTASP_DATA field of the OTASP TransportMessage contains a22

    segment other than the final segment of the OTASP Data MessageCapsule,23

    the base station should increment SEQ_NUM modulo 32 and should set the24

    value of the B/F field to 00.25

    - If the OTASP_DATA field of the OTASP TransportMessage contains the final26

    segment of the OTASP Data Message, the base station should increment27

    SEQ_NUM modulo 32 and should set the value of the B/F field to 01.28

    The base station should remain in the Conversation Task.29

    2. OTASP Transport Confirmation Message:30

    The base station should set the SEQ_ACK field to the value of the SEQ_NUM field31

    received in the OTASP TransportMessage being acknowledged, and should remain32

    in the Conversation Task.33

    2.2.4.2 Message Reception1

    While the base station is in the Conversation Task, the following messages can be received2

    autonomously from the mobile station, in addition to those listed in 3.6.4.4 of [1]. When3

    any message is received, the base station should perform all actions specified in 3.6.4.4 of4

    [1] that apply to a message reception. The base station shall take the actions specified5

    below for each message:6

    1. OTASP Transport Message:7

    If the value of ESN received in the OTASP Transport Message does not match the8

    ESN that identifies the mobile station being activated, the base station should9

    ignore the message.10

    If the value of ESN received in the OTASP Transport Messagematches the ESN that11

    identifies the mobile station being activated, the base station should do the12

    following:13

    The base station should send an OTASP TransportConfirmation Message.14

    If the value of the B/F field of the received message is 11, the OTASP_DATA15

    field of the received message contains the OTASP Data MessageCapsule in its16

    entirety. The base station may discard any incomplete OTASP Data Message17

    being reassembled, and should process the OTASP Data Messageas specified in18

    Section 4.19

    If the value of the B/F field of the received message is 10, the base station may20

    discard any incomplete OTASP Data Message being reassembled, and should21

    store the OTASP_DATA field of the received message as the first segment of an22

    OTASP Data Message Capsule to be reassembled. The base station should23

    store the value of the SEQ_NUM field of the received message in RX_SEQ_NUM.24

    If the value of the B/F field of the received message is 00 and a segmented25

    OTASP Data MessageCapsule is being reassembled, the base station should26

    perform the following:27

    - If (RX_SEQ_NUM + 1) modulo 32 is equal to the value of the SEQ_NUM field28

    of the received message, the base station should store the OTASP_DATA field29

    of the received message as the next segment of the OTASP Data Message30

    being reassembled, and increment RX_SEQ_NUM modulo 32.31

    - If RX_SEQ_NUM is equal to the value of the SEQ_NUM field of the received32

    message, the base station may discard the OTASP_DATA field of the received33

    message.34

    - If neither RX_SEQ_NUM nor (RX_SEQ_NUM + 1) modulo 32 is equal to the35

    value of the SEQ_NUM field of the received message, the base station may36

    discard the OTASP_DATA field of the received message and may discard the37

    incomplete OTASP Data Message being reassembled.38

    If the value of the B/F field of the received message is 00, and no segmented1

    OTASP Data MessageCapsule is being reassembled, the base station may2

    discard the OTASP_DATA field of the received message.3

    If the value of the B/F field of the received message is 01 and a segmented4

    OTASP Data MessageCapsule is being reassembled, the base station should5

    perform the following:6

    - If (RX_SEQ_NUM + 1) modulo 32 is equal to the value of the SEQ_NUM field7

    of the received message, the base station should store the OTASP_DATA field8

    of the received message as the last segment of the OTASP Data Message9

    Capsule being reassembled, should increment RX_SEQ_NUM modulo 32,10

    and should process the OTASP Data Messageas specified in Section 4.11

    - If RX_SEQ_NUM is equal to the value of the SEQ_NUM field of the received12

    message, the base station may discard the OTASP_DATA field of the received13

    message.14

    - If neither RX_SEQ_NUM nor (RX_SEQ_NUM + 1) modulo 32 is equal to the15

    value of the SEQ_NUM field of the received message, the base station may16

    discard the OTASP_DATA field of the received message and may discard the17

    incomplete OTASP Data MessageCapsule being reassembled.18

    If the value of the B/F field of the received message is 01, and no segmented19

    OTASP Data MessageCapsule is being reassembled, the base station may20

    discard the OTASP_DATA field of the received message.21

    The base station should remain in the Conversation Task.22

    2. OTASP Transport Confirmation Message:23

    If SEQ_ACK is equal to the sequence number of the last OTASP TransportMessage24

    sent, the base station may transmit the next OTASP Transport Message; otherwise,25

    the base station should ignore the message. If the DMU_CRC_OK field indicates26

    that the CRC of the OTASP Data MessageUnit did not check at the mobile station27

    (see 2.2.3.3), the base station should resend the OTASP Data Message. The base28

    station should remain in the Conversation Task.29

    2.2.4.3 Forward Voice Channel Message Format30

    2.2.4.3.1 OTASP Transport Message31

    When the base station sends an OTASP Transport Messageon the Forward Voice Channel32

    (FVC), it shall use the following variable-length message format:33
