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

There are many ways to optimize wireless and broadband internet services instead of increase more international internet bandwidth. They are;

1. Applying data accelerator with client server platform

With data accelerator, wireless and broadband internet subscribers will have multiple choices to display the type of internet traffic they will receive on the laptop/computer. Data accelerator can improve the speed of internet access experienced by wireless and broadband internet subscriber while they use client software. Basically data accelerator is client server platform where the entire of internet traffic will be forwarded by server to international internet gateway and server will cache it. While wireless and broadband internet subscriber activate the client software, server will reduce and remove some unnecessary packets before subscriber receive the traffic. It is very important applying data accelerator to the wireless and broadband internet service to achieve stable connection and speed

2. Bandwidth management

Telecommunication companies can not manage the behavior of wireless and broadband internet service to limit the download file, real time streaming video (RTSP) and attaching huge file while sending e-mail. Telecommunication companies can not say to wireless and broadband internet service to limit them. What they can do is manage the bandwidth to the entire of purpose while subscriber access to the internet. Telecommunication companies used to will manage the total of international internet bandwidth they have and divide it into several segments. For example, telecommunication companies will limit download access to have only maximum 30 Mbps, http protocol will have 50 Mbps, and Real Time Streaming Video (RTSP) file will have 20 Mbps etc. Bandwidth management makes sure that each protocol and application will have dedicated bandwidth and they will be interrupted when one protocol or application was saturated

Data accelerator and Bandwidth Management will reduce many complaints of wireless and broadband internet service and give significant benefits to the wireless and broadband internet subscribers

1. Voice over IP (VOIP) gateway

Voice over IP (VOIP) gateway responsible to handle all international calling services were dialed by subscribers. The main function of Voice over IP (VOIP) gateways are compressing the voice, routing the call, digit number translation policy and change the packet to IP base. Voice over IP (VOIP) gateway retrieves subscriber’s call from Mobile Switching Centre (MSC) and the process the call before deliver it to the destination number. Voice over IP (VOIP) gateway will generate the call detail report (CDR) when a call is established between source number (A number) and destination number (B number)

2. Internet bandwidth

Voice over IP (VOIP) service is internet protocol (IP) bases packet which mean that call will be delivered to destination number to the IP packet. To deliver the Voice over IP (VOIP) service, telecommunication companies require international internet bandwidth where the calls will come and go. Telecommunication companies used to already have international internet bandwidth either they leased from Internet Service Provider (ISP) or they build by their selves for many purpose. It means that no issue on the international internet bandwidth while telecommunication companies plan to have international internet bandiwdht

3. International Voice over IP (VOIP) partner

Telecommunication companies than need international Voice over IP (VOIP) partner that responsible to the end of destination number. More often, international Voice over IP (VOIP) partner will have another Voice over IP (VOIP) partner as well to deliver the call to destination number

The benefit of Voice over IP (VOIP) service is cheap tariff rather than IDD service. Voice over IP (VOIP) service is quite easy to be deployed rather than IDD service which require dedicated international link gateway with high capacity. Voice over IP (VOIP) service also need less investment rather than IDD service.

When telecommunication companies plan to have high speed internet access through mobile broadband internet service, they should plan this service carefully other wise there will be massive problem in the future and will come a lot of complaints from subscribers. There are many things need to be considered by telecommunication companies while they decide to introduce High speed internet access through mobile broadband internet service, they are;

1. There will be high demand to High speed internet access through mobile broadband internet service while telecommunication companies launch the service

High speed internet access through mobile broadband internet service is new experience for mobile telecommunication users. Telecommunication companies should have optimistic that there will be a lot of subscribers will access High speed internet access through mobile broadband internet service at the short time and they should anticipate this growth with deploying good network infrastructure

2. Upgrading the capacity on network element which support High speed internet access through mobile broadband internet service such as Base Transceiver Station (BTS), International bandwidth capacity

High speed internet access through mobile broadband internet service is giving new experience to subscriber to browse to internet up to 7 Mbps. Therefore, telecommunication companies should have high capacity on the back end to support High speed internet access through mobile broadband internet service. BTS and international bandwidth capacities are the common issues. Telecommunication companies should plan to upgrade periodically on BTS where they has high occupancy and international bandwidth as well.

3. Optimizing the service of High speed internet access through mobile broadband internet service with many ways bandwidth optimization, limiting the user capacity etc

There are many ways can be considered to have High speed internet access through mobile broadband internet service is still on the acceptable performance such as bandwidth optimization at the internet gateway and limiting to subscriber of High speed internet access through mobile broadband internet service.

Beside all the things above, telecommunication companies should consider what the packages plan they want to sell to the subscribers. They can adopt several mechanisms such as bandwidth quota that allowing subscribers to have certainty bandwidth capacity. To have more interested, telecommunication companies also can offer cheap tariff of high speed internet access through broadband mobile service

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

PDSN process the request before subscriber reach the internet and do the necessary action to make sure that the session reach the right another telecommunication network while make a data service session. Globally, PDSN has functions as below;

1. Manage the radio-packet (RP) interface that connect to BSC

As we know that the main issue on wireless internet service is lack of Radio Frequency (RF). While subscriber is connected but do nothing (dormant time) session between subscriber, BTS and BSC will be terminated but connection between BSC to PDSN still there until subscriber browse to generate the traffic

2. Provide routing and packet management service

Session from subscriber will be routed to internet gateway so then subscriber able to browse to internet. In another case subscribers will browse to internal application service such as Value Added Service (VAS). PDSN will route the subscriber’s request to proper application service

3. Applies IP services

Each session from subscriber will be allocated a certainty IP Pool. Each session has different IP Pool. PDSN will allocate this IP Pool to each subscriber

4. Collects packet billing data

Usually charging system is done by another network element (charging gateway). PDSN will forward the charging process to the another network element

5. Authentication packet connections

At the first when the subscriber make a dial up session, PDSN will sent to authentication to AAA server to identify whether this is valid subscriber or not

The important thing related to PDSN is Authentication, Accounting and Authorization (AAA) process. Accounting is related to charging process that will be done by charging gateway. Subscriber will be charged based on policy was applied on the charging gateway to each subscriber. Authentication process is identification process to each subscriber before they are allowed to access the internet. The things that will be checked by Authentication server are account (username and password) and mobile phone number(MIN – Mobile Identification Number). Meanwhile Authorization process is the access policy to the subscriber

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

1. 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

It is different with IDD service, while Telecommunication Company decides to build a VOIP service, there will be some network infrastructures needed to be inserted to the current one. VOIP service is running on the existing network, telecommunication company just need to make sure that the call was delivered to the destination at abroad and conversation happen between calling and called number. Generally, the new network infrastructures that needed are;

1. VOIP gateway
2. International Link/Bandwidth
3. International VOIP partner

The international call from subscriber will forwarded from Mobile Switching Centre (MSC) to VOIP gateway and digit translation is happening here. This new digit number will be encapsulated to the IP base packet and will be delivered to the International VOIP partner. VOIP gateway responsible to covert traditional call bases (ISDN and Signaling) coming from subscriber to the IP base packet.

Since VOIP service is international call base, telecommunication company should deploy international link or bandwidth to deliver and retrieve a packet. It is like a bandwidth needed by mobile internet service.The international link could be dedicated E1 transmission that will be terminated from Telecommunication Company to the international partner. Usually, Telecommunication Company prefers to provide internet bandwidth to deliver the VOIP traffic since they can insert it to another service which requires internet bandwidth as well such as mobile internet service .

Telecommunication Company did not deliver the VOIP traffic to the destination number directly. The international call will be forwarded to their international VOIP partner at abroad and let them deliver it to the proper destination number. International VOIP partner may forward the call to the destination number directly through VOIP service as well or they will forward it to their partner as well. It is depending on the level of international VOIP partner has been chosen by Telecommunication Company. Telecommunication Company also can connect their international call to several International VOIP partner to distribute various traffic scenario. This scenario usually was applied to give various tariff calls to certainty countries

To avoid poor connection on mobile broadband internet service, usually Telecommunication Company applies several technical and non technical solutions on the current network infrastructures. Non technical solution could be limiting the capacity of wireless internet subscribers. It means that Telecommunication Company will not expand network infrastructures to accommodate new subscribers and they only maintain the current subscribers. Meanwhile technical solution could be;

1. Adding new network infrastructures to cover the poor performance on mobile broadband internet service at certainty areas

By this mechanism, it means Telecommunication Company should install Base Transceiver (BTS) at the areas where wireless or mobile broadband internet service is getting poor performance. This is expensive way and usually they will do this mechanism once those areas are definitely lack of RF resources

1. Applying different charging bases

This is to differentiate the quality of service on mobile broadband internet service. To the areas where no RF capacity issue, time base charging is the first option. Meanwhile to the areas experience lack of RF capacity, charging system base on volume is fairy. This is avoiding more complaints from subscribers

Both mechanisms above are caused by RF capacity issue. Meanwhile RF capacity is not the main point where unstable connection to wireless internet service is going on. The other one is international bandwidth capacity. To optimize international bandwidth capacity issue, Telecommunication Company could apply one of the following mechanisms;

1. Inserting bandwidth management to the existing network infrastructures

Telecommunication Company will limit the bandwidth capacity to each protocol while subscribers browse to internet. For example, streaming video will only have 5 Mbps to all subscribers, downloading file has 5 Mbps, http protocol is highest priority etc

1. Inserting cache/shape engine

By this mechanism, Telecommunication Company will give an option to their subscribers whether the traffic they will retrieve on the laptop/compute is shaped or normal. While they choose shaping option, the speed will be faster but the quality image will decrease
