The unit acts as a base station emulator, and it provides built in logging of signaling procedures to enable full testing and investigation. In this way the unit provides a cost effective environment to perform testing. APPLICATIONS The unit is able to reduce development costs by providing a comprehensive test tool with diagnostics during development. It can also reduce costs by enabling pre-interoperability testing to be run on a fully independent platform. SYSTEM OVERVIEW The CDMA-AIME is designed to emulate CDMA base stations. It incorporates a full protocol stack and provides full access to the Layer 3 forward link via the scripting language used. The Layer 2 signaling operates automatically but can be modified by the user to enable Layer 2 testing. All Layer 2 and 3 messages are time stamped and logged for subsequent review. Tests can be run to test mobile performance including fax and data, mobile power control, pilot pollution, authentication and encryption. The number of base stations and complexity of the testing performed is governed by the choice of For the very latest specifications visit www.aeroflex.com hardware platform, three of which are available. A library of messages specified by IS-95A, -B, ARIB STD-T53 and IS-2000 is provided. (This is a subset of the complete library). Messages may also be modified and new messages can be added. One of the main applications of the CDMA-AIME system is to perform CDG interoperability (stage 2) tests. A suite of test cases can be provided to enable this testing to be accomplished efficiently. To enable the system to be used to its greatest potential, it has a WindowsTM user interface that runs on a separate PC. There is an activity window to display status messages along with a Layer 2 /3 window. A campaign manager is included to allow a series of test cases to be run sequentially. and a random (non-OCNS) noise source. This is ideal for generating a repeatable and accurately controllable level of noise for mobile testing where fading is not needed, for example in Pilot Pollution investigations. An EVDO upgrade also offers AWGN as an option. REVERSE CDMA CHANNEL The CDMA-AIME supports the reception of one or more Reverse CDMA Channels that can be: • Access Channel or • Reverse Traffic Channel consisting of a Fundamental Code Channel and up to 7 Supplemental Code Channels or up to 2 Supplemental Channels. HANDOFF CAPABILITY FULL SYSTEM DETAILS AND DATA Forward Code Channels The standard AIME supports transmission of up to 16 Forward Code Channels which can be any combination of: • Fundamental Code Channels • Supplemental Code Channels • Supplemental Channels • Paging Channels • Sync Channels The unit can support 2-way Soft Handoff, on any call type including medium speed data (MDR) calls with up to 7 Supplemental Code Channels. MULTIPLEX OPTION AND RADIO CONFIGURATION SUPPORT The system supports Multiplex Options 1 to 16 (Radio Configurations 1 to 5, one Fundamental and up to two Supplemental Channels or one Fundamental and up to 7 Supplemental Code Channels). Primary and Secondary traffic are also supported. The user specifies the Multiplex Option to be used in the script and this can then be changed dynamically during the call. • Pilots In addition, the user can specify the transmission of various error conditions including: Each one of the 16 Code Channels is fully and independently programmable and the following parameters are configurable by the user: • Corrupted frame quality indicator • Frame rate • Corrupted modulation symbols (after block interleaving) • Long Code Mask • Frame Offset • Quick paging channels • Power control sub-channel state (where relevant) One or more of these channels can be used to provide an Orthogonal Channel Noise Source (OCNS) on an otherwise un-used Walsh code. FORWARD CDMA CHANNELS The Forward Code Channels can be combined onto one or two Forward CDMA Channels. The user can program the properties of these Channels independently including: • PN offset • Total Channel Output power • Individual code channel relative powers • Walsh Code of individual Code Channels • Propagation delay In addition to these two Forward CDMA Channels, can also transmit another simplified Forward CDMA Channel that contains just a pilot • Corrupted frame bits after adding the frame quality indicator SERVICE OPTION SUPPORT The unit supports most non-proprietary Service Options. Where data service options utilize application Layers above Air Interface Layer 3, standard commercial off-the-shelf (COTS) software is used where applicable. Summary of Service Options Supported Service Option Number Designated/Type of Service used directly or the user can incorporate them into other scripts. They can be freely copied and modified subject to licence. These procedures include testing aspects of handoff, SMS, pilot pollution, power control, propagation delay, call setup, concurrent services etc.. A facility is also provided to run a sequence of test cases as a test campaign. The user can vary the length and the content of the test campaign altering the parameters between successive runs to enable comprehensive test campaigns to be created. CONTROL OF EXTERNAL EQUIPMENT The CDMA-AIME is capable of controlling additional external equipment (not supplied with the system), via the PC.

The user has full control of the protocols, procedures and timings used via the script. The user can send and receive any signaling messages and parameters in those messages, including incorrect or erroneous messages. The user can also construct new messages not yet in the IS-2000 message catalog. The timing of messages sent on the Forward Link can be set in 20 ms intervals relative to the reception of messages on the Reverse link, or relative to system time. All logged messages are also time stamped with the time they are sent or received by the 1X-AIME/1. The user can make the signaling procedures as simple or as complex as required for the type of testing to be performed. Other options may be supplied if required. The messages can also be filtered to reduce the amount of information displayed. A “find” feature is included. SYSTEM CONTROL The CDMA-AIME System uses a COM compatible software interface, therefore the user can use the script interpreter built into the User Interface. SCRIPT LANGUAGE The AIME uses an ActiveX scripting engine that allows SAX BASIC (Visual Basic) Script to be used to control the system. PROCEDURES AND TEST CASES SUPPLIED The standard system is supplied complete with a number of example-scripted procedures based on CDG Standards. These can be For the very latest specifications visit While the script is running, the system logs all signaling messages, on both Forward and Reverse links on the PC for future review. RETRIEVABLE AND SETTABLE PARAMETERS The Retrieve Parameters Message, Parameters Response Message and the Set Parameters Message are all fully supported and ID values of up to 65535 may be used to allow manufacturer - specific parameters to be investigated FAX AND DATA TESTING The CDMA-AIME allows the user to perform functional tests of Fax and Data calls and data tranfer very simply and easily. All the necessary protocols are provided in the software supplied. www.aeroflex.com FAX TESTING RADIO LINK PROTOCOL LOGGING The necessary protocol stack up to, and including, the T30 protocol (RLP, PPP, TCP/IP, App Interface, T30) is included in the System software. The script has a number of commands to control the Fax procedures. RLP signaling messages are logged with other signaling messages. RLP packets can be logged under user control from a test script. Forward and reverse packets are logged separately. The Fax data itself is supplied in TIFF format and users can supply their own data or use the three ITU files supplied with the system (T.24 Figures 01, 09 and 10). This method of providing Fax capability allows for many more future enhancement possibilities than the method of using a standard Fax software package. Good, Data Error, Rate Error and Erased frames values are displayed and logged for a Markov Data call. MOBILE STATION POWER CONTROL TESTING The CDMA-AIME system provides the user with all the necessary low-level control to perform comprehensive testing of Mobile Power Control. Normally the system uses automatic Closed Loop Power Control of the Mobile to hold the Mobile power at an optimum level. However, the user also has full manual control of this process via the script. The system can be configured with one or two fundamental Forward code channels each with independent power control sub-channels. When required, the user has full control of the power control bit puncturing on each code channel on a 20 ms basis. While the system has not been designed to provide accurate absolute power measurement of the Mobile’s transmit power, measurement of the relative power of the Mobile’s steps can be performed by the System and absolute power can be measured with other external equipment. This allows most power control scenarios to be simulated and tested PILOT POLLUTION TESTING MARKOV DATA LOGGING TRAFFIC LOGGING Layer 1 forward and reverse data payload is logged for future review. Date and time stamp, direction, status, frame type and raw data content are all captured, and forward and reverse data can be filtered as required. USER INTERFACE The WindowsTM User Interface allows the user to control all aspects of testing. It also provides extra features for use in the post processing of results. ACTIVITY WINDOW An Activity window displays various status messages to the user during the running of a Test Script. It can also be used to prompt the user as necessary during testing for example “Please place a call from the Mobile now”. SIGNALING WINDOW This displays the signaling messages, either in real time during a test run, or for subsequent review from a saved file. When displaying messages in real time during a test run the window can be ‘paused’ so that an area of interest can be viewed without waiting for the test run to complete. The fine control of the 6304, means the CDMA-AIME is ideal for simulating pilot pollution scenarios for R&D testing of Mobile Handsets. The output power of the Forward Channels in each code channel can then be varied over a 20 dB range with 0.05 dB resolution with a time resolution down to 20 ms. This allows the user to rapidly vary the relative pilot levels in a completely controlled and repeatable manner. AUTHENTICATION AND ENCRYPTION TESTING For CDMA2000 1X, Authentication, Voice Privacy and Message Encryption are all fully supported in the CDMA-AIME. Authentication can be tested by using known challenge/response pairs in the script, or by the user implementing the required Authentication algorithm in a script. Alternatively the user can simply ignore the Mobile’s response in the script. Encryption can be tested by using a known Public or Private Long Code mask in the script. LOGGING FACILITIES SIGNALING MESSAGE LOGGING All forward and reverse link signaling messages are detected by the test system and passed to the Controller PC for time stamping and logging. These messages are decoded and made available for display at the GUI. FILTERING AND SEARCHING All messages can be ‘filtered’ so that only those of interest are displayed in the window. In addition the ability to quickly search for a particular message or event in a saved file is also provided. • Wide variety of software options to provide comprehensive set of test facilities • Covers frequency band classes 0, 1, 3, and 4, with available hardware upgrade to cover band class 6 The basic system consists of the 6204 Dual Rack Assembly containing two 6304s and RF combiner unit as well as all the necessary interconnection cables The system is connected to the Mobile-under-test via an RF antenna port using a coaxial cable.
