CDMA 2000 R-UIM and ME Parameters

In the mobile wireless system, mobile station (MS) refers to a users tool that consist of Mobile Equipment (ME) and user identity card. Each mobile wireless system has their own type and name of this user identity card. As example In GSM, the user identity card is known as Subscriber Identity Module (SIM) card and in CDMA, the user identity card is known as Removable User Identity Module(R-UIM) card. In this user identity card is saved the needed user information as well as the security information for users. This time, I share the complete parameters that can be found in R-UIM card and Mobile Equipment (ME) of CDMA 2000 for better understanding of client side CDMA 2000.

R-UIM Card Parameters

Here the parameters that used in the CDMA R-UIM Card:

Authentication and keys generation algorithm, usually the algorithm is CAVE algorithm.
A-key which is used for key generation algorithm. A-key is programmed directly into R-UIM by telecommunication operators or can be programmed through over-the-air (OTA). This A-Key cannot be accessed by ME.
SSD which is for authentication functions and key generation. SSD cannot be accesed by ME
Temporary secret parameter which is used to generated ciphering key for authentication processing
COUNT which is accessible for ME. COUNT will increase incrementally when use the network.
IMSI which consist of IMSI_M and IMSI_T. IMSI_M is consist of Mobile Identification Number (MIN) in 10 digit. IMSI_T is not related with MIN. Subscription Identity is accessible for ME.
RUIMID which is the parameter which saved inside of EF RUIMID with '6F31' as identifier
Service Programming Code (SPC) which has '6F33' as identifier. SPC is used for OTASP/OTAPA procedure.
NAM_LOCK which has '6F3' as identifier. NAM_LOCK is saved lock/unlock status of NAM

ME Parameters

In the Mobile Equipment (ME), there are:

The entire algorithm that used to encrypted the voice, user data and signalling messages.
Key processing for ECMEA and ECMEA_NF
ME Electronic Serial Number (ESN)
Control Mechanism for OTASP/OTAPA procedure
