General Description

Intelligent Call Assistant (SGA-ICA) is a system designed to improve call connection success rates of inbound roaming subscribers. Since phone numbers are not always stored with the international prefixes in cell phones, connecting roamers’ calls are often unsuccessful, and the subscribers simply get a signal or a voice announcement stating that the dialed number does not exist. For most of the cases it means lost calls, and for some cases subscribers also change the roaming operator and retry their calls over there. This problem, and hence the potential loss of operator's profit, can be eliminated by informing the subscriber about his/her dialing error, and suggesting corrective actions. Utilizing the features of SGA-ICA the operator can inform the roaming subscriber in a text message about the proper dialing method. Since this message contains the correct number (with the proper prefixes) as well, the subscriber can easily initiate the call by extracting this number from the text (usually by simply pressing a single button of the phone on the message text).

In this way SGA-ICA allows the operator to provide helpful information for roamers dialing with inappropriate (or missing) prefixes. In order to do so, the operator should route such calls to the SGA-ICA on the basis of number analysis. The distinguishing features of these calls: foreign calling party number and unknown called party number.

Main Properties, Features

During the lifetime of the SGA-ICA solution, we have developed two releases (see below their functionality lists) based on the most wanted operator requests. Additional features are on our product development roadmap. Their implementation depends on customer requirements.

SGA-ICA - 1st Phase

CPU utilization: irrelevant Memory utilization: irrelevant Releases the call (after a short timeout) with a predefined release cause Handles and maintains real and virtual speech channels, too Assembles Call Detailed Record (CDR) about closed calls Sends information SMS to subscriber about scheme of correct dialing In order to send SMS to SMSC several protocols can be applied, e.g. CIMD2, UCP, SMPP Uses templates for SMS sending 100 languages can be used. Selecting of language is configured by operator, based on

subscriber’s identity Frequency of sending SMS can be configured Logging operation in different levels (Off, Normal, Detailed, Debug) Working process can be controlled by user-friendly graphical user interface (GUI) Capacity: 1000 SMSs / hour, using two E1 PCM connections After a missed call, SMS can be sent within half second Availability: 98%

SGA-ICA - 2nd Phase

Supplies all functionalities and features of SGA-ICA -1st Phase Maintenance functions (e.g. alarms) realized by generating SNMP Trap messages for

Network Operating Centre Can advise a corrected dial number in all possible cases Statistical decision support for correction in case of non-typical mistaken numbers

Working of System

The Main Function of the System

If foreign subscriber in inbound roaming state fails the dialing, the system disconnects the call. The subscriber gets information about dialing rules. So, the subscriber can call again in the proper way.

The Call Termination equipment (ICA): Receives the IAM message Answers with ACM message

Disconnects the call in given delay time: sends the REL message. The Release Cause is defined by the operator

Sends an informative SMS to the caller Receives the RLC message.

Suggesting a Corrected Dial Number

Program can optionally advise a corrected dial number in all possible cases. Based on the complete, corrected B-number inserted to the SMS the user can simply and instantly initiate the call properly.

The program can make the correction in the following cases: Roamer calls a number of a foreign provider using IDD of his own country but it is different

than the local IDD. Roamer calls a number of his provider adding “0” and CC to the national format of his own

country without IDD. Roamer calls a number of his provider adding “0” to the international format of his own

country without IDD. Roamer calls a number of his provider adding CC to the national format of his own country

without IDD. Roamer calls a number of his provider without IDD. Roamer calls a number of the local provider without IDD. Roamer calls a number of his provider using national format without IDD.

Detailed rules are described in Appendix.

Call Termination, Handling of Speech Circuits

The ICA equipment can handle both real and virtual speech circuits. No physical circuits related to virtual speech circuits. This will not cause any problem, because no calls established on them.

The calls are disconnected only after a given time delay, - which is adjustable - otherwise MSC would repeat the call.

It is also possible to give a shift offset for the speech circuits, so two PCM trunks can be related to the same point code.

ISUP Message Handling

Establishing of ISUP CICs

BLO{CIC} ---> BLA{CIC}RSC{CIC} ---> RLC{CIC}UBL{CIC} ---> UBA{CIC}CGB{range} ---> CGBA{range}GRS{range} ---> GRA{range}CGU{range} ---> CGUA{range}

Message sequence diagram

Sending of SMSs

After disconnecting the call a short message will be sent to the caller over the selected protocol.

The SMS sending period can be set, to avoid submitting large quantities of SMS to the same subscriber. For example 1 hour has to elapse between two SMSs regardless the amount of the missed calls.

Forwarding of SMSs is performed by the preferred SMS protocol handler module (SMPP, CIMD2, UCP, or SS7).

After maximum of 5 seconds the SMS will be submitted to the SMSC.

Configuring the system

The program can be configured by setting parameters of the INI file.The name of INI file is the same of EXE, advised: SgaCallTerminator.ini.The INI file must be placed in the same folder as the EXE.Some configuration values can be modified on GUI, too and their actual values can be saved on the GUI.

The INI file contains the following entries:

After the start up of the program the following graphical interface will be available:

Controls of GUI

The name of the program and the version number can be seen on the top of the screen. The next line is the menu bar for executing the operations. Under this line you can find the quick launch buttons for fast access of more frequently used

operations and the CPU-usage percent. A moving train indicates the processing state. On the main part of the screen resides the log list. Below the log you can see the status of the “A” and “B” interface:

1. line: o Letter of the linko PCM link.

Red – When the Sga-47 card does not detect any PCM signal Gray – Normal operation

o MTP2 Red – When the Sga-47 card could not build up an SS7/MTP2 connection Gray – Normal operation

o …bps - Transfer speed, number of the inbound LSSU and MSU bits in the previous second

2. line:o „E”. Error counters: PCM, MTP2, DSP (card), MSU, TCAP errors. The

interpretation of the error counters: „pcm” = Number of the PCM breakdowns detected by the Sga-47 card. „mtp2” = Number of the MTP2 level breakdowns of the SS7 links. „dsp” = Number of the communication errors with the Sga-47 card’s

processor. It indicates a serious problem if it is not 0 all the time. „msu” = Number of uninterpretable, or misdirected (wrong point code)

msu-s. „tcap” = Number of wrong TCAP messages.
