To deploy facebook application on wireless internet service, telecommunication companies should prepare below network infrastructures:

1. client server BREW application
2. wireless internet network which including Public Data Serving Node (PDSN), Charging Gateway, AAA server and CDMA network which including BTS, BSC and HLR
3. Internet gateway to connect to outside (Facebook.com)

The key point to introduce Facebook application on wireless internet service which actually has speed up to 153,6 kbps is deploying client – server BREW application. The key parameters while deploying client – server application are:

1. How much maximum speed can be consumed by low end mobile phone which will access Facebook application
2. Memory utilization  and disk capacity that will be allocated on the mobile phone

Client application in this case is Facebook client that will be inserted on the mobile phone with BREW platform. Algorithm and applications details should be pre-defined and should match with the Server before they deployed on the mobile phone. Meanwhile Server application is middle ware server which interact with mobile phone and facebook server. Beside the algorithm and protocol that should have match with the client, server application should proper and same with algorithm on the facebook server as well. This algorithm which called Facebook Algorithm Programming Interface (API) should be synchronized every time once facebook server made any changing

There are many reasons why facebook application is getting error. The errors that may comes to mobile phone users while they access the application such as, error connection, network problem, application is temporary unavailable, session is expired, there seems to be an errors on the application and many else. Those errors are commonly coming from the wireless network and facebook application itself especially on the Facebook Application Programming Interface (API). When the errors comes from wireless internet network such as error in connection and network down, the problem will appears to the entire of wireless internet service and not only to facebook application. Telecommunication Company understands well what they should do while this error comes to mobile phone users while accessing facebook application or others wireless internet services such as CDMA 1x or GPRS. However when the errors come from the facebook application itself such as Application Programming Interface (API) protocol than the real problem to facebook application is coming. Application Programming Interface (API) is set of software so one software can interact with others software. Application Programming Interface (API) is required by mobile facebook developer to interact with facebook application. Open source Application Programming Interface (API) protocol is the most popular one used by mobile facebook developer while they deploying mobile facebook client on the middleware server. The main issue is that this  open source Application Programming Interface (API) changing more often and without notification to mobile facebook developer to synchronize their facebook clinet. And the result, mobile phone with facebook client will always generate many errors caused by this Application Programming Interface (API) changing

1.         Satellite Internet Access

Satellite Internet Access is used to use by telecommunication companies and Internet Service Provider (ISP) to provide fix and mobile/wireless internet service. However, telecommunication companies used to use satellite as the backup access once the primary access is going down. The primary access is optical fiber or high capability Synchronous Digital Hierarchy (SDH) up to 1 Giga bytes

2.        Wi-Fi Hotspot

Wi-Fi hostspot is used to use by Internet Service Provider (ISP) to provide wireless internet service on the particular area and limited coverage

3.         Celluar Internet Access

Telecommunication companies through their network can provide massive mobile/wireless internet service to the mobile telecommunication subscribers.  There are many kind of mobile/wireless internet service which can be provided by telecommunication companies based the technology platform they adopted. Telecommunication companies with CDMA platform will introduce CDMA 1x to provide mobile/wireless internet service. Meanwhile GSM platform will introduce GPRS to provide mobile/wireless internet service.

Technology platform that used by telecommunication companies is very critical to provide mobile/wireless internet service. To provided high speed internet access, telecommunication companies should migrate the current technology (CDMA 1x and GPRS) to the next generation platform. High speed internet access refers to term mobile broadband which allow mobile telecommunication subscriber to get speed up to 3 Mbps and more. Depending on the network platform, telecommunication companies should migrate to the mobile broadband technologies such as EVDO, HSPA, WiMax and LTE

Basically the flow is as follows -

–        the subscriber dials #777 and places a data call

–        the MIN is validated by the MTX

–        the BSC forwards the session request from the PCF to the PDSN

–        the PDSN and the handset begin negotiating a PPP session (LCP phase)

–        the MN supplies a user name and password

–        the PDSN forwards an Authentication request to the RADIUS Authentication server

• if the Authentication server reply with a REJECT the PDSN tears down the session
• if the Authentication server does not reply the PDSN retries until it receives a reply or retries are exhausted.  If retries are exhausted the PDSN tears down the session
• If the Authentication server reply with an ACCEPT the PDSN continues with the session setup

–        the PDSN completes setting up the PPP session to the MN and allocates an IP address

–        the PDSN sends an Accounting START request to the RADIUS Accounting server

• if the Accounting server does not reply the PDSN keeps retrying
• if the Accounting server reply  with an acknowledgement the subscriber’s session is allowed to start

–        traffic flows over the subscriber’s session until the session is terminated

–        radio resources are released

–        the PDSN sends an Accounting STOP request to the RADIUS Accounting server

If the Accounting server does not reply the PDSN keeps retrying

The first thing is providing backup link to internet service provider. Telecommunication companies could have more than one of internet service provider to forward the traffic of mobile broadband internet service. Both internet service providers could be load share the traffic or active and standby. Actually telecommunication companies should invest much money to have more than one internet service provider. As you know that leasing internet bandwidth in Indonesia is very expensive compared to others country. As the result, usually redundant system of internet bandwidth to support mobile broadband internet service is given lower bandwidth compare to primary link. It is about a half of primary bandwidth capacity. For example if primary bandwidth link has 100 Mbps than secondary bandwidth link will have 50 Mbps. In addition, the secondary link is a backup link and no traffic as long as primary bandwidth link is UP

The second thing to prevent outage on broadband internet service either 3G or EVDO is upgrading the network capacity especially Base Transceiver Station (BTS), Base Station Controller (BSC) and transmission media. There will be huge traffic of broadband internet service will come to BTS and BSC. Telecommunication companies will increase the capacity on both network elements to handle that huge traffic. By upgrading BTS and BSC mean that telecommunication companies should install more BTS and BSC at the current area to support huge traffic from broadband internet service. Despite of adding the number of BTS and BSC, telecommunication companies also need to install more transmission capacity to carry out the huge traffic

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.

Telecommunication companies will do some efforts to reduce huge complaints while lack of resource on both telecommunication network infrastructures which support mobile broadband internet service happen. What they will do to make sure availability on both resources are:

1. Monitoring to the traffic of international gateway

Telecommunication companies will have gateway router to international gateway where traffic from mobile broadband internet service comes and goes to international internet gateway. The utilization of router interface toward international gateway is very critical to be monitored every single minute. Telecommunication companies are used to have a graphic monitoring tool to indicate how much bandwidth capacity of mobile broadband internet service was occupied by subscribers. Usually router interface has bandwidth capacity higher than internet bandwidth it self which has only around 50-100 Mbps whereas router interface could reach 1 Gbps.  Telecommunication companies will keep monitoring to the pattern traffic of international bandwidth on this router and once it saturates, they need to do some efforts such as increasing the bandwidth of mobile broadband internet service. Monitoring to the traffic pattern of this bandwidth is also to make sure that once traffic is dropped suddenly, quick response can be executed

2. Monitoring to the capacity of each BTS

To the telecommunication companies which has dedicated channel for broadband internet service purpose, there will be no interruption from voice service once the RF capacity reach the maximum capacity. Meanwhile to the telecommunication companies which combining between voice and data channels, usually they set higher priority to the voice service rather than data. As the result, there will be more often lack of RF resource for data service. Telecommunication companies will monitor each of BTS to indicate which one has saturated traffic and they will take necessary action once it happens

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

High demand from mobile telecommunication subscribers on the mobile broadband internet service definitely produces more revenue to the telecommunication companies even though some of telecommunication companies campaigned cheap tariffs to one or more their telecommunication services especially to the data and voice services. To give better telecommunication services especially to the data and voice services e.g. mobile broadband internet service to the mobile telecommunication subscribers, telecommunication companies should make sure that telecommunication infrastructures able to handle huge traffic come from subscribers. Usually telecommunication companies will enhance their telecommunication infrastructure with many methods to optimize data and voice services such as:

1. Deploying VOIP service to handle long distance call

Once voice traffic increase very fast especially long distance call, telecommunication companies will face critical issue that is link transmission to carry out the traffic from mobile telecommunication subscribers. More over, usually telecommunication companies did not have transmission backbone such as optical or Synchronous Digital Hierarchy (SDH) networks. Deploying Voice over IP (VOIP) network to handle long distance call is a make sense solution. With the VOIP network, the same mount of link transmission could carry out more than four times traffic from mobile telecommunication service compared to traditional call

2. Applying data optimization on the data service environment

The main problem on data service e.g. mobile broadband internet service is issue on Radio Frequency (RF) capacity which reserve channels for data service from mobile telecommunication service especially to the telecommunication companies which did not dedicated allocation for data service. Beside RF issue, internet bandwidth also shares the problem on data service. Telecommunication companies used to optimize the entire of data service environment with data optimization which will be applied on the client (mobile telecommunication subscribers) or data service infrastructures. Data optimization could be inserting new device such as data accelerator and bandwidth management on the mobile broadband internet service.

The goal of deploying VOIP and applying data optimization is mobile telecommunication subscribers will experience better telecommunication services
