`
`PREFACE
`
`These technical requirements form a standard for Over-the-Air Service Provisioning of mobile
`stations. A mobile station operating in either the analog or the spread spectrum (CDMA) mode
`conforming with TIA/EIA-95-B, TIA/EIA/IS-95-A (inclusive of TSB74), or ANSI J-STD-008 and
`this standard can be activated over the air in any system conforming with these standards.
`
`The scope of this standard covers over-the-air provisioning of mobile station operational
`parameters, provisioning of System Selection for Preferred Roaming parameters, and
`provisioning of Service Programming Lock.
`
`This standard does not address the quality or reliability of Over-the-Air Service Provisioning,
`nor does it cover equipment performance or measurement procedures.
`
`SECTION SUMMARY
`
`1. Introduction. This section defines the terms, references, protocols, and network
`reference model used in this document.
`
`2. Message Transmission Procedures. This section describes the lower-layer procedures
`used for transmission of messages for Over-the-Air Service Provisioning.
`
`3. Mobile Station Procedures. This section describes the mobile station procedures for
`Over-the-Air Service Provisioning.
`
`4. Base Station Procedures. This section describes the base station procedures for Over-
`the-Air Service Provisioning.
`
`5. Key Exchange Procedures. This section describes the requirements for key exchange
`procedures.

`
`NOTES
`
`1. The following verbal forms are used: “Shall” and “shall not” identify requirements to be
`followed strictly to conform to the standard and from which no deviation is permitted.
`“Should” and “should not” indicate that one of several possibilities is recommended as
`particularly suitable, without mentioning or excluding others; that a certain course of
`action is preferred but not necessarily required; or that (in the negative form) a certain
`possibility or course of action is discouraged but not prohibited. “May” and “need not”
`indicate a course of action permissible within the limits of the standard. “Can” and
`“cannot” are used for statements of possibility and capability, whether material,
`physical, or causal.
`
`2. Footnotes appear at various points in this specification to elaborate and further clarify
`items discussed in the body of the specification.
`
`3. Unless indicated otherwise, this document presents numbers in decimal form.
`
`Binary numbers are distinguished in the text by the use of single quotation marks. In
`some tables, binary values may appear without single quotation marks if table notation
`clearly specifies that values are binary. The character ‘x’ is used to represent a binary
`bit of unspecified value. For example ‘xxx00010’ represents any 8-bit binary value such
`that the least significant five bits equal ‘00010’.
`Hexadecimal numbers (base 16) are distinguished in the text by use of the form 0xh…h
`where h…h represents a string of hexadecimal digits. For example, 0x2fa1 represents a
`number whose binary value is ‘0010111110100001’ and whose decimal value is 12193.
`Note that the exact number of bits in the binary representation of a hexadecimal number
`strictly depends on the implementation requirements for the variable being represented.
`
`4. Numeric information is used to describe the operation of the mobile station. The
`following subscripts are used in this document to clarify the use of the numeric
`information:
`
`•
`
`•
`
`•
`
`•
`
`“s” indicates a value stored in a mobile station’s temporary memory.
`
`“r” indicates a value received by a mobile station over a forward analog channel or a
`CDMA Forward Channel.
`
`“p” indicates a value set in a mobile station’s permanent security and identification
`memory.
`
`“s-p” indicates a value stored in a mobile station’s semi-permanent security and
`identification memory.
`
`5. The term “mobile station” is equivalent to the term “personal station.”
`
`6. IMSI_T Parameter Block does not apply for the mobile station conforming with
`TIA/EIA/IS-95-A (inclusive of TSB74) or ANSI J-STD-008.
`
`7. IMSI_M in this document is equivalent to IMSI defined in TIA/EIA/IS-95-A (inclusive of
`TSB74) or ANSI J-STD-008.

`
`1 INTRODUCTION
`
`1.1 General Description
`
`Over-the-Air Service Provisioning (OTASP) consists of the following features provisioned over-
`the-air:
`
`• Download of NAM operational parameters.
`
`• Electronic Key Exchange for securely establishing the A-key.
`
`•
`
`System Selection for Preferred Roaming (SSPR) for providing mobile stations with
`information allowing acquisition of the preferred system in an area.
`
`Service Programming Lock (SPL), if provided, prevents the over-the-air provisioning of certain
`mobile station parameters by an unauthorized network entity.
`
`This document describes Over-the-Air Service Provisioning in CDMA and analog systems. The
`procedures defined are intended to be extendable and flexible enough to be used with future air
`interface specifications. The procedures in this document do not require support for
`continuation of the service provisioning process following a CDMA-to-analog handoff.
`
`1.2 Terms and Numeric Information

`group of at least two dialed digits (System Selection Code) that specify the user selection of a
`Band and a Block operated by the selected service provider.

`brief digital messages may be sent from a base station to a mobile station or from a mobile
`station to a base station.
`
`Authentication. A procedure used by a base station to validate a mobile station’s identity.
`
`Authentication Center (AC). An entity that manages the authentication information related to
`the mobile station.
`
`Base Station. A fixed station used for communicating with mobile stations. Depending upon
`the context, the term base station may refer to a cell, a sector within a cell, an MSC, an OTAF,
`or other part of the wireless system. (See also MSC and OTAF.)
`
`CRC. See Cyclic Redundancy Code.
`
`Cyclic Redundancy Code (CRC). A class of linear error detecting codes which generate parity
`check bits by finding the remainder of a polynomial division.
`
`Electronic Serial Number (ESN). A 32-bit number assigned by the mobile station
`manufacturer, uniquely identifying the mobile station equipment.

`

`
`TIA/EIA/IS-683-A
`
`ESN. See Electronic Serial Number.
`
`Forward CDMA Channel. A CDMA Channel from a base station to mobile stations. The
`Forward CDMA Channel contains one or more code channels that are transmitted on a CDMA
`frequency assignment using a particular pilot PN offset.
`
`Forward Analog Voice Channel (FVC). An analog voice channel used from a base station to a
`mobile station.
`
`Forward Traffic Channel. A code channel used to transport user and signaling traffic from
`the base station to the mobile station.
`
`HLR. See Home Location Register.
`
`Home Location Register (HLR). The location register to which a MIN/IMSI is assigned for
`record purposes such as subscriber information.
`
`Home System. The cellular system in which the mobile station subscribes for service.
`
`IMSI. See International Mobile Station Identity.
`
`IMSI_M. MIN based IMSI using the lower 10-digits to store the MIN.
`
`IMSI_T. IMSI not associated with MIN. 15-digits or fewer.
`
`International Mobile Station Identity (IMSI). A method of identifying stations in the land
`mobile service as specified in ITU-T Recommendation E.212.
`
`Long Code Mask. A 42-bit binary number that creates the unique identity of the long code.
`See also Public Long Code, Private Long Code, Public Long Code Mask, and Private Long Code
`Mask.
`
`LSB. Least significant bit.
`
`MCC. See Mobile Country Code.
`
`Mobile Country Code (MCC). A part of the E.212 IMSI identifying the home country. See
`ITU-T Recommendation E.212.
`
`Mobile Directory Number. A dialable directory number which is not necessarily the same as
`the mobile station’s air interface identification, i.e., MIN, IMSI_M or IMSI_T.
`
`MIN. See Mobile Identification Number.
`
`MNC. See Mobile Network Code.
`
`Mobile Identification Number (MIN). The 34-bit number that is a digital representation of the
`10-digit number assigned to a mobile station.
`
`Mobile Network Code (MNC). A part of the E.212 IMSI identifying the home network within
`the home country. See ITU-T Recommendation E.212.
`
`Mobile Station. A station, fixed or mobile, which serves as the end user’s wireless
`communication link with the base station. Mobile stations include portable units (e.g., hand-
`held personal units) and units installed in vehicles.
`
`Mobile Station Originated Call. A call originating from a mobile station.
