INTRODUCTION

This Standard was prepared by Technical Specification Group C of the Third Generation Partnership Project 2 (3GPP2).This Standard presents recommendations for supporting a mobile station equipped with a Mobile Equipment IDentifier (MEID) [10] in the OTASP Systems defined in [2], [3], [4] and [5].

The OTASP feature allows a potential wireless service subscriber to activate (i.e., become authorized for) new wireless service, and allows an existing wireless subscriber to make changes in existing services without the intervention of a third party.

For the initial provisioning, the Electronic Serial Number (ESN) is used to identify the mobile station. ESN is a 32-bit number assigned by the mobile station manufacturer, uniquely identifying the mobile station equipment. Due to the ESN exhaustion, the MEID was introduced in the cdma2000^®1 systems as the alternative to ESN for new mobile stations complying with [7].

During the migration period from ESN to MEID, Pseudo-ESN is used by the MEID15 equipped mobile stations. Pseudo-ESN is a 32-bit number derived from MEID and used in place of ESN. For the provisioning, however, Pseudo-ESN may not be used to uniquely identify a particular mobile station since Pseudo-ESN is not unique.

In order to solve this problem, the following new capability is introduced in this Standard.

• Enhanced Protocol Capability Messaging - This provides the means for the base station to ascertain the detailed capabilities of the mobile station, such as supported band classes, operating modes, and MEID.

This Standard uses the same structure and section numbering as [2], [3], [4] and [5], except for all the references. Sections of this Standard that remain unchanged relative to [2], [3], [4] and [5] are represented using ellipses contained within brackets ([...]). Modified sections are either reproduced in their entirety or use the [...] notation to represent unchanged portions. Within modified sections, change bars indicate the specific paragraphs, figures, or table cells that have changed. Within modified paragraphs and table cells, strike-throughs indicate deleted text and underlines indicate new text.
