Nowadays, many issues and trend of crimes such as robbery, drug addicts, rape, murder or snatch had arisen via the whole world. These arise of crimes was happening shows that the public especially victims seek for a proper assistance in the soonest time from emergency agencies such as police, fire fighter or hospital. To overcome those crimes a lot of effort and works had been done with many countries everywhere in the world with their goal to be a less crime country. One of a good solution through the launch of the emergency centre channel by phone number like 999 hotline number was used in Malaysia. By phone, the operator has been recorded the all information required such as location and type of emergency (Widiasa Wijaya, 2013). Then, the operator will channelling the line to the respected agencies based on the caller’s problem faced but if it identify as a prank call, the line will not proceed to related agencies.

This is a common flow for the emergency call centre. The crime is solved based on the information provided and how fast the information delivered to the agencies targeted such as, a police officer who are on duty will be alerted from the provided information and have to move right away to the reported location. The major aspect for instant assistance not be able to reach at soonest time when the distance between the incident occur and the emergency agencies. Whereby via the emergency phone line, 45% robbery incidents reports used in England and Wales.(Michael Ovelgonne, 2010)

The advancement in development of wireless communications and mobile database technology has provide a greatly convenience for lives nowadays and has promote the usage of cell phone. Therefore the extensive to application of Location Based Services (LBSs) for emergency handling has played an important role in deal with public emergencies and as a value-add to the 999 service. The implementation and the prototype development of Emergency Information Retrieval by using LBSs as a mobile application is hoped that will be able to solve the real distress problem.

1.1 Problem Statement

All distress call will be channelled to a centralised unit called “cell centre”. The call center operator are working within 24 hours based on rotating shift duty. The operator have to be working routine like administrative works such as reporting the calls and then channeling the information throughout respective division. The existing emergency system quite primitive without having proper tools like digital map, mobile communication. The only communication between the call center and the emergency agencies is via walkie-talkie or radio based communication.

According to (Peter Kolesar I, Albert Pedrinan & Peter Stein B, 1976), mentioned that a lot of focus has been done on the calculation or timeframe been taken while operator on the line, call routing and call queues. The researcher focus on simplifying the flow of emergencies information flow by utilizing the usage of pull location based service. They also mentioned that the answering process during the line is busy are not on FIFO basis at that time. Therefore, if the use of location based service is utilized, the call centre operator for 999 which handled fully by Telekom Malaysia can automatically store into database. The proposed project will be targeted user like police and RSS feed and pull location based service technology will be used to retrieved information.

Another constraint that faced in the emergency call workflow due to the current system are using that being used manually. This condition have been given impact when there is a few number of operator duty able to receive calls in certain reach peak hour and also involving much of wasting time while on run. If the line is busy, for those who is the callers that need for help would have to wait on the line and this waiting can turn into problem for them. It is because their information or help that they need does not arrive on that time. Perhaps, the criminal suspect can escape in that wasted time and this situation causes a lot of criminal may leave free of charge without any punished. The statistics of crimes that unsolved will increase continually. Sometimes the delivered information is not clear during the calls arrive for call centre system is being recorded. This can cause a misunderstandings between the operator for the emergency centre site and the call centre.

Based on the Figure 1.1 below, the viewer may see the current flow of call handling that able to explain on the 999 call flow. Once the This figure was taken from on Project Director MERS999 (Ir Rozinah Anas, 2008). The research is on Bridging Public And Agencies For Disaster & Emergency Situations under Telekom Malaysia (TM). She had already stated that once the 999 Response Center was handle by TM Call Center get the emergency details, the information then will be transmitted through making calls to related agencies like police, fire department, ambulance and civil defense based on the emergency type.

Figure 1.1 : The 999 Call Flow for the MERS999 which Handle by TM in Malaysia (Ir Rozinah Anas, 2008)

As stated by (Dr Rosidah Ibrahim, 2010), the current emergency call flow was happen to have no automatic routing system, high in drop call, long queue, abandon call and no access during call congestion and this will lead to a very low public confidence.

By having the use of pull location based service, the flow of information is smooth as the call centre agents of 999 will just need to insert data to the database and later the information can be retrieved by using the smart phone. Time taken can also be reduced as there is no need to channel information manually.

Concerning the problems discuss, this is should not be happening in Malaysia as a country that in moving towards technological oriented in terms of works and service delivery. The improves quality of life, must be enhanced the current emergency caling system to counter every possibility. Furthermore, the public citizen also need to play a major role to ensure that the country is a safe place for others. By the implementation of Emergency Information Retrieval by using local based services and through its prototype development it is hoped that it will be able to solve the real life problem.
