As the result, high innovation of Value Added Service (VAS) such as BREW platform where allow subscriber to get many features and download content application through mobile internet service will have high occupancy day by day after launch the service. Telecommunication companies should anticipate this situation and plan to design high reliability of Value Added Service (VAS) system

Utilization of server which running the VAS application should be placed at high priority while they plans to build VAS system. Server will be hit by huge mobile telecommunication subscriber through mobile internet service while they subscribed to high innovation of VAS service such as accessing Facebook via low end bundling mobile phone. Beside hit by huge subscribers, the VAS application server will carry out huge traffic as well. To anticipate huge traffic from huge mobile telecommunication subscriber through mobile internet service, VAS server should be design to have high reliability. The thing should be consider by telecommunication companies while they plan to provide Value Added Service (VAS) to their subscriber are:

1. High occupancy of application server

To provide high occupancy server than should be consider high specification of application server which handle VAS traffic. VAS traffic is increasing very fast and telecommunication companies could not replace the servers once they hit by huge traffic after sometimes but the specification of server is low. Therefore high specification of application server is needed to be consider at the first development than no activity to replace to hardware on the production system

2. High availability of VAS system

To give high availability of VAS service through mobile internet service , the system which handles VAS traffic should have high availability. To provide high availability, redundant system is the best mechanism. Actually it is high investment but will guarantee that the system will run forever with no service interrupted once the primary system goes down. Redundancy system of VAS service is involving many network elements beside VAS server itself. The transmission link to reach the VAS application server where used to locate to different office is required to be protected by creating link redundancy

3. High capability support system

Infrastructures which support VAS service through mobile internet service need to be designed with high capability as well to make sure there is no failure point on the entire of network. The support system could be routes, catalyst (switch) etc

High demand on broadband internet service either 3G or EVDO service is giving new opportunity for each telecommunication companies to provide broadband internet service instead of traditional wireless internet service e.g. CDMA 1x Rtt and GPRS. High demand on broadband internet service is also giving a challenge for each telecommunication companies especially to provide smooth migration from the traditional network to the next generation network. There are many things need to be prepare once telecommunication plan to migrate current technology to the next technology generation.

The first thing, they should decide which the next technology proper to the current one. Suppose, telecommunication companies have CDMA platform and CDMA 1xRtt is the technology to provide wireless internet service, then the proper next technology is EVDO (Evolution Data Only/Optimized). CDMA 1xRtt technology will give limited speed (153 kbps) to wireless internet subscriber. It is not recommended speed to compete with telecommunication companies which offer broadband internet service with 3G platform. Migrating to the EVDO technology is the best solution to give high speed internet experience to the mobile internet service

The second thing is trial EVDO technology to the existing CDMA 1xRtt platform. Trial is intended to identify whether any interoperability issue between CDMA 1xRtt with EVDO platform. Usually telecommunication companies will assign particular Base Transceiver Station (BTS) and Base Station Controller (BSC) with Public Data Service Node (PDSN) which already have EVDO license. EVDO platform should give high speed internet experience up to 2.7 Mbps while testing. EVDO is the next generation of CDMA 1x platform and it means there will be no significant changing on the current telecommunication infrastructure while they deploy EVDO platform

The third is upgrading the current CDMA 1x platform to the EVDO platform. EVDO is high speed internet access which requires high capacity on each network element which supports it. Network element which should be upgraded to the high capacities is Base Transceiver Station (BTS), backbone transmission and internet gateway.

From . . . → Read More: Building a Voice Over IP (VOIP) Service]]> VOIP services are needed by telecommunication company since many subscribers has many purposes by doing that such business activity, contacting their family etc. Telecommunication Company prefer to provide international call service with VOIP rather than International Direct Dial (IDD) service which need a license from the regulatory institution beside it gives cheaper tariff. From subscribers’ view, the different between both VOIP and IDD service is while they make a dial session. VOIP service is valid to their subscribers only and subscribers should dial with additional prefix. Meanwhile, IDD service is valid to any subscribers from any telecommunication company with certainty prefix number which already given by regulatory institution.

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

The three parties companies which required for supporting Telecommunication Company at least two companies, they are called as vendors and content providers

1. Vendor company

Vendor is responsible to provide network infrastructures needed by Telecommunication Company to run a telecommunication service. Right now there are many types of support given by vendors to the telecommunication company. It was that Telecommunication Company should buy the entire of network infrastructures they will deploy. Vendor will responsible to install and maintain by contract agreement for certainty period and once the contract agreement is over, they can extend or cut it. In this scenario Telecommunication Company should invest much money to buy all of telecommunication infrastructures and they could come from. The infrastructures they should buy e.g. Home Location Register (HLR), Home Visitor Register (VLR), Mobile Switching Centre (MSC), more than a thousand Base Transceiver Station (BTS), Base Station Controller (BSC), Short Messaging Service Centre (SMSC), transmission system etc. they are needed to support the core network of telecommunication service and still many else needed to support more services

The new scenario is called Managed Service (MS). In this scenario vendor responsible to plan, install, operate and maintain the entire of telecommunication network day to day. Some Telecommunication Company make a deal with them that vendor should invest their equipment and share revenue they achieve. On the Managed Service (MS) scenario, Telecommunication Company will focus to create a telecommunication products and services and trying to get subscribers as many as possible

2. Content Providers (CP)

Content Providers responsible to provide many services offered by Telecommunication Company to their subscribers such as download content service. They also provide applications needed by Telecommunication Company to support their services such as Customer Relationship Management (CRM) application, call centre purpose. The types of cooperation also could many ways. Some of them should deploy their own application and some should just provide the contents

Actually, there are more three parties involved to the telecommunication business such as sub contractor whom usually responsible to install the telecommunication equipments
