Value Added Service (VAS

Beside voice, data service and messaging (SMS) services, Value Added Service (VAS) can be utilized to generate high revenue. Basically Value Added Service (VAS) adopt current service; it is only optimizing current service with new innovation and inserting some telecommunication infrastructures. The sample of Value Added Service (VAS) service which utilizes voice service is Ring Back Tone (RBT), on the messaging service (SMS) e.g. content messaging whereas on data service such as BREW service

BREW service is client service bases. Telecommunication companies should prepare should to provide contents, application, charging matrix and database. Meanwhile client application is installed on the mobile phone. Value Added Service (VAS) which using BREW platform usually provided by telecommunication companies with bundling mobile phone schema

BREW service

Server platform responsible to process session from client and response the mobile subscribers request with appropriate service. Server platform will contain application system which enable the session on BREW platform by following pre define algorithm. Application system which defined on the server platform should synchronize with the client application which installed on the mobile phone. Value Added Service (VAS) on BREW service requires contents which will be hit or downloaded by client application on the mobile phone. Server platform manages those contents and make sure that client will get appropriate content while they hit or download them. Server platform also defines what kind of charging schema will be implemented on such Value Added Service (VAS). Usually such Value Added Service (VAS) has subscription charging and pay per download. Data base will maintain the subscriber profile who already subscribed to such Value Added Service (VAS)

Embedded mobile phone

Meanwhile client application which will be deployed by manufactures on the mobile phone should match and synchronize with application on the server other wise there will come a problem in the future. Mobile phone which embedded BREW platform will have some parameters which identify manufacture and the service provider

Innovation of telecommunication services are really needed to maintain mobile telecommunication subscribers and increasing the new one and finally gaining much more telecommunication companies’ revenue. Value Added Service (VAS) through mobile internet serviceis one of the telecommunication services which can be utilized as it could generate much kind of innovations. Value Added Service (VAS) is additional service or feature which can be inserted to the existing telecommunication service (voice, SMS and data service). Value Added Service (VAS) through mobile internet service is running by following existing telecommunication services.

There are many types of innovation of telecommunication services which can be produced by Value Added Service (VAS). The most valuable, popular and innovative Value Added Service (VAS) through mobile internet service is additional services which running under SMS and Data service. VAS service which referring to SMS service is the old one but it still running till now and generating significant revenue for the telecommunication companies. The most attractive of VAS through mobile internet service is which running under Data Service. The type of VAS service which referring to SMS and Data services can be divided it into;

1. VAS service based subscription service

Subscription service is typically running under SMS service. Mobile telecommunication subscribers should register to the service through certainty short code number before they can receive the service. The content of VAS service on subscription bases could be horoscope, news, football update, game information, movie review etc. The subscription service which is needed by teenager such as prediction on relationship is usually subscribed by many teenagers. Mobile telecommunication subscriber will receive a SMS daily bases and it could be one or more SMS per day. To stop the service, subscribers should send a SMS with certainty format to the certainty short code number

2. VAS service which embedded on the mobile phone

The new innovation of Value Added Service (VAS) is the service which involves data service to carry on VAS traffic and the application service is embedded on the mobile phone subscribers. This service is called BREW service. Mobile telecommunication subscriber is no more sending SMS with certainty format to certainty short code number. The entire of services are available on the mobile phone which already injected with BREW platform. Subscriber is just clicking the menu to accessing the VAS service which could be subscription service, download content such as wall paper, ring tone, game. The most attractive of VAS service which embedded on the mobile phone is flexibility to insert the service and advance the service based on market request such as facebook feature etc

Mobile shopping service

engineer — Wed, 21 Oct 2009 05:00:26 +0000

It was that subscribers should register to the service which held by telecommunication companies and three parties to have mobile shopping and content services such as ring tone, wallpaper and game. This is a registration service where subscriber should register via SMS to certainty short code and they will receive the update information about the service daily base. Subscriber then can download the content through mobile internet service e.g. GPRS or 3G service through their mobile phone. It means subscriber should do some effort before they download the contents

New innovation of Value Added Service (VAS) on mobile internet service to fulfill mobile shopping service needed by subscriber is telecommunication companies provided end to end the system to support the service. That is VAS service based on BREW platform. With this scenario, telecommunication companies provided mobile phone, application on the mobile phone and application server. BREW platform is giving an alternative solution to the low end handset instead of current mobile phone shopping which required high end handset and support WAP application (Java application)

Through the new mobile shopping service, subscriber will have more options before they decide to buy something to enrich their mobile phone. The benefits of new mobile phone shopping from the subscriber perspective are;

1. Subscriber will be able to browse to any available contents

Mobile shopping application is available on the handset and usually telecommunication companies will give free of charge to browse any content available (ring tone, wallpaper and game) on mobile internet service . They will be charge if subscriber decides to buy one or more of them

2. Subscriber can preview the content they would like to buy

Before subscriber decide to buy, they can preview the ring tone, wallpaper or game through mobile internet service to make sure that they are working and resulting as they expected

Meanwhile from the telecommunication perspective, the benefits of mobile phone shopping are;

1. Single point of service

Mobile shopping service on the mobile internet service with this scenario requires that telecommunication companies act as the single point of service which provides application server, contents and mobile phone/handset injected with BREW platform

2 Cheap tariff

Since no three parties involved in the mobile which used to provided a part of system, telecommunication companies can give a cheap tariff to the entire of service e.g. subscription service, download content etc

3. High flexibility on the system

Telecommunication companies can change the application server, manage the contents, and application on the handset anytime they want to for many reasons

Identifying the problem of Value Added Service (VAS) services

engineer — Sat, 17 Oct 2009 16:24:06 +0000

There will be a lot of work should be done while they are receiving a lot of complaints from their subscribers according to Value Added Service (VAS) service through mobile internet service. VAS service is involving entire of network elements which to run voice call service and for some VAS services through mobile internet service they involve network element of data service. it is more difficult to identify the root cause of problem and fix it if its VAS service through mobile internet service is involving data service equipment. It means that telecommunication companies should check the entire of network element to find and fix it. There will be many three parties which responsible to the application service and vendors which expert on the telecommunication core network such as Base Transceiver Station (BTS), charging gateway, Intelligent Network, Public Data Serving Node (PDSN), Data Communication such as router, catalyst and load balancer

Value Added Service (VAS) through mobile internet servicewhich involves data service equipment such as download contents, mobile shopping, subscription service and service based on BREW platform, it is very though to identify partial problem such as error “network busy” during certainty period e.g. busy hour rather than we notice that the service goes down. While telecommunication companies experience this partial problem for example partial problem on download contents on BREW platform, the action they will do to identify root cause of problem and fix it soon are;

1. Identifying the pattern of problem through the mobile phone/ handset

Collecting the pattern of errors while subscriber experience such as whether subscriber completely getting a problem while accessing the download content, mobile shopping and subscription services or they are getting problem while accessing to particular application and what the message will appear on the mobile phone/handset while problem is coming

2. Identifying the Radio Frequency (RF) capacity

Network busy is the common issue on wireless/mobile internet service including Value Added Service (VAS). If the location which covers the service is having good quality of signal but the service is still getting problem, it means that RF capacity is not contributing to this partial problem. Confirmation that the capacity of signal is sufficient to carry out the traffic including VAS service is needed to go to the further investigation

3. Tracing the session from the central process of data service such as Public Data Serving Node (PDSN)

All sessions to access the entire of application on VAS services will go through PDSN node. By tracing a particular session which experience error “network busy”, we can identify whether the request from subscriber already sent to the application server and responded back to the subscriber or not

4. Identifying packet data received at data communication equipment, application server, Domain Name Server (DNS) and charging gateway

By tracing to the application systems related to VAS service we can identify packet data which come and go the each application service and analyze whether each element already receive and response the request from subscriber or not. This section will identify which part of network element that did not run proper while a request from subscriber is coming

BREW application problem

engineer — Thu, 15 Oct 2009 17:54:29 +0000

BREW client (mobile phone injected with BREW platform) for many reason such memory capacity, default application for mobile phone that should be available and price will have expire time while it is trying to get BREW application from the BREW server on the mobile internet service . It is starting when subscriber push the application bottom available on the BREW client mobile phone and few second after this effort, BREW client must get an application they are trying to get other wise BREW client will generate error “network busy” and session is fail. It is depending on the handset/mobile phone capacity how long expiry time will be configured on that mobile phone but usually it is about 20 seconds. It means that after 20 seconds since the subscriber access to the application on mobile internet service and getting no response from the BREW server, BREW client will terminate the session

Late response from BREW server could be caused by many things such as network topology from user (BREW client) to BREW server, the capacity of BREW server and response time from the network element on mobile internet service between them such as charging gateway etc. Once it is coming, telecommunication companies should identify this case and resolve immediately. The first thing they need to do is identify which network element that contributes to this late response. To get this information, telecommunication engineer have to do some effort below;

1. Dump the traffic from the network element which involved to the BREW application such as BREW server, charging gateway and Domain Name Server (DSN) server

They can use tcpdump command if they are using Linux operating system to identify whether request is arriving to those network elements and responded back by them or not. It is also can be done if the network element such as charging gateway on the mobile internet service has the tool to capture the full packet come and go through it.

2. Snoop the traffic from the data communication network such as router etc

Snoop has the same goal that is the identify whether the traffic come and go through the data com network such as router

3. Tracing from the handset it self

Each handset/mobile phone vendor usually has a tool to get information about any packet come and go through the mobile phone/handset

Actually the critical issue while late response happened to the application service based on BREW platform is contributing from the network topology itself where BREW application implemented on the mobile internet service . This is how the traffic will be routed from the mobile phone/handset to the BREW server and vice versa. The best network topology to run the BREW service is efficient network where it is required less time to deliver the traffic from source and destination address

Types of facebook applications on the VAS service

engineer — Sat, 26 Sep 2009 15:37:17 +0000

Facebook fever is definitely optimized by several telecommunication companies to spoil their subscribers and keep loyal. Usually Telecommunication Company integrated the facebook application into Value Added Services (VAS) through mobile internet service. This is totally different with accessing facebook through Opera Mini or WAP applications. While accessing through both application means subscribers access to facebook using wireless or mobile internet access directly either CDMA 1x, 3G, GPRS or EVDO. Meanwhile through VAS service, subscribers should do some effort to get access to facebook such as subscripting via SMS etc

There are several types of integrating facebook application to the VAS services through mobile internet servicethat can be adopted by Telecommunication Company.

1. Partial facebook feature via SMS

It was that subscriber need to subscribed to facebook service provided by telecommunication company to get some features of facebook such as updating the status, adding new friend and commenting on the friend’s status. This is SMS or text service where subscriber will not view full features of facebook. All activity did by sending a SMS with particular format to the short code provided by Telecommunication Company. In this scenario, Telecommunication Company will forward the request sent by subscribers to facebook address. The benefit is any mobile phone can do this service which means that subscriber can access the facebook with Telecommunication Company as the mediator to facebook address.

2. Full facebook feature via BREW platform

It is different with service mentioned above, in this scenario subscriber can access fully facebook feature through their low mobile phone with embedded BREW platform. The problem to access facebook directly through mobile phone is it is requiring high end mobile phone with Java Application to support WAP or Opera Mini applications. Telecommunication Company should provide mobile phone with embedded BREW platform and definitely with cheap price. In this scenario, fully features of facebook is part of VAS service through mobile internet service so there will be a lot of services on the mobile phone such as download content, subscription services, etc.

Integrating facebook to the VAS service is revolutionary service and believed will produce massive responded from subscribers at the short time. In addition, Telecommunication Company provides a cheap mobile phone to with many attractive features. The thing need to be anticipated by Telecommunication Company is the internet bandwidth capacity since subscriber predicted will keep connected to internet for long time

Integrating facebook to the VAS service

engineer — Sun, 20 Sep 2009 16:48:35 +0000

The Flexibility of Value Added Service can adopt any kind of established service to be one of the features of Value Added Service (VAS) contents. For example is integrating the most popular social network right now, facebook, as part of Value Added Service (VAS) features. Usually, Value Added Service (VAS) through mobile internet service has local network features which mean that all available features are coming from dedicated local servers. In the CDMA platform, one of the valuable VAS service through mobile internet service is download content service based on BREW platform. In this case, BREW server is dedicated local server then BREW client (mobile phones) can access the service directly with no need to go to internet.

By integrating facebook as the part of Value Added Service (VAS) through mobile internet service, it means the mobile phone should be allowed to access to two paths of traffic;

Application service (download content or subscription services) to local network located on the dedicated server
Internet service but to the certainty address, that is facebook address

Since BREW client has static menus on the mobile phone where subscribers just push to the available menu and will redirect to the particular service (application service or facebook address) then, need to be designed backend system in order to meet such requirement. Some requirement need to be considered while deploying VAS service through mobile internet service which integrated with facebook feature on mobile phone is;

1. The account injected on the BREW client should be able to access application service and facebook address.

As mentioned above that there are two paths of traffic, it is critical to design routing policy on the network infrastructures that involved to this service2

2. Internet bandwidth capacity

As we know that facebook fever is happening right now and providing a cheap mobile phone embedded BREW platform with facebook feature will make people keep “on line” longer. It means that million people make a session at the same time and longer. as the result the internet bandwidth capacity will increase very significant

3. Radio Frequency (RF) capacity issue

More people will occupy the RF capacity at the same time and for long time. Resource availability is very critical to make sure that each session from subscriber will be served by network otherwise a lot of complaint will come due to subscribers are getting network busy while accessing the service

4. Security policy

It is very important to make sure that all service available on the mobile phone is controlled and no chance to the intruder to access internal network through mobile internet service to make a change the configuration and flood it with the huge unused traffic. In this scenario, Telecommunication Company should make sure that even subscriber will be allowed to BREW server located at internal network and allowed to browse to facebook address but nothing they can do except accessing to the authorized services

How to implement BREW services?

engineer — Wed, 16 Sep 2009 15:15:43 +0000

Value Added Service (VAS) through mobile internet service is giving flexibility for the telecommunication company to custom existing telecommunication service they already run or create new innovation based on subscribers request. BREW platform gives more choices for Telecommunication Company to create many Value Added Service through mobile internet service which embedded on the subscriber’s mobile phone. Usually there are two mechanisms how the telecommunication company implement Value Added Service (VAS) through mobile internet service based on BREW platform at their bundling mobile phone;

1. Static BREW service

BREW service include client on mobile phone and service which handle application and content management. Static BREW service means that when a telecommunication company plan to create more applications, mobile phones which embedded BREW platform as a client will not be able to be upgraded or modified to the different application. Applications what has been inserted to this mobile phone can be changed to different one. In other words, if Telecommunication Company creates new BREW service, subscriber should change the mobile phone to be able to access new BREW service. In this mechanism, subscriber will have limited service. it is what has been installed on the existing mobile phone

Dynamic BREW service

Dynamic BREW service is giving more choices to subscribers since they can add or change to the new BREW service. This mechanism is giving flexibility to the subscriber to choose which service they love. BREW platform is QUALCOM property. Telecommunication Company should share the revenue to QUALCOM once they agree to deploy BREW service. Usually QUALCOM will charge each application that they have been offered to their subscribers. It means that more application, there will more revenue should be shared to QUALCOM

Telecommunication services based on BREW platform can be update any time when a special moment come or what the popular trend being interested by many people. To accommodate new BREW service through mobile internet service, Telecommunication Company should take different effort depending on what mechanism they have been deployed;

1) Static BREW service

As the existing mobile phone embedded BREW platform will be not able to access new BREW service, Telecommunication Company should produce new mobile phone with new BREW service embedded and add new application on the BREW server. It means that telecommunication company need to spend much money to produce million mobile phones supported with new BREW application

2) Dynamic BREW service

As the existing mobile phone is allowed to modify, change or remove BREW application, then Telecommunication Company only need to add new BREW application on the BREW server. It means that Telecommunication Company will save much money as they do not need to produce million mobile phones
