GPRS – General Packet Radio Service

General Packet Radio Service (GPRS) is a data service designed for second generation GSM and PCS networks. It uses a packet radio principle to carry end user’s packet data protocol like IP or X.25 information from mobiles to external packet data networks and visa versa. GPRS optimises the use of radio and network resources. Separation between the base station subsystem and network subsystem is maintained and the network subsystem can be reused with other services. GPRS radio channel reservation and allocation is done flexible from 1 to 8 radio interface timeslots per TDMA frame and timeslots are shared by all the active users. Up and downlink are allocated separately. The radio interface resources are shared dynamically between data and speech services according to operator’s preference and base station load.

Several radio channel coding schemes are specified to allow data rates from 9 kbits/s up to 171 kbits/s and eventually 384 kbits/s per user. The available bandwidth per channel depends upon which coding scheme is used. CS1 provides connectivity under “all conditions” and delivers a user throughput of up to 9.05 kbits/s, While CS4 requires excellent radio signal (Carrier to Interference ration of 27 dB) and delivers a user throughput of up to 21.4 kbits/s.

GPRS is designed to support intermittent and bursty data transfers and occasional transmission of large volumes of data, and point-to-point and point-to-multipoint services are also supported. GSM network requires two new network elements for GPRS. The Serving GPRS Support Node (SGSN), which performs security functions, mobility management and access control. Frame Relay connects the SGSN the base station system. The Gateway GSN (GGSN) is used for interworking with external packet-switched networks. GPRS is standardised in ETSI (European Telecommunications Standards Institute).


Ten Romantic Tips for Lover…

Romantic Tips:

1. Give your lover a dozen roses — and do it with a creative twist. Give eleven red roses and one white rose. Attach a note that reads: “In every bunch there’s one who stands out — and you are that one.”

2. Fake a power outage at home. (Loosen the fuses or throw the breaker switches.) With no TV to tempt you . . . with no computer to occupy you . . . with no furnace to heat you . . . you pretty much have no choice but to get out the candles, huddle around the fireplace and be romantic!

3. Get your partner a wristwatch. Inscribe it with: “I always have time for you.”

4. Attach a $100 bill to a Victoria’s Secret catalog, along with a note to him saying, “You choose.”

5. Identify that one pivotal event that brought the two of you together. Celebrate that event every year.

6. Practice even-day/odd-day romance: On even days it’s your turn to be romantic, and on odd days it’s your partner’s turn.

7. Following a bubble bath you’ve prepared for her, wrap her in a towel that you’ve warmed up in the dryer.

8. Write your partner a love letter or poem on one sheet of paper. Glue it to thin cardboard, cut it up into puzzle-shaped pieces, then mail all the pieces. Or, mail one puzzle piece per day!

9. Remove all the paper strips (that say “Kisses” on them) from a couple hundred Hershey’s Kisses. Fill a jewelry box with them. Wrap ’em up and present them to your partner. Write a certificate explaining that the slips are coupons redeemable for one kiss each.

10. Doesn’t your partner deserve a trophy for being the “World’s Best Lover”? Trophy shops have a wealth of ideas waiting for you. Just think of the romantic possibilities of plaques, medals, ribbons, nameplates, certificates and banners. And they all can be personalized, engraved, lettered or monogrammed.

Shayari : Samunder adhura hai kinaro ke bina

Chand adhura hai sitaro ke bina,
Gulshan adhura hai baharon ke bina,
Samunder adhura hai kinaro ke bina,
Jeena adhura hai tum jaise yaaro ke bina


hamari mehfil ko fasana mil gaya
hamari gazlon ko afsana mil gaya
Aapki Dosti aisi mili dost jaise
khuda ki taraf se koi nazrana mil gaya


Bewafai Shayari : Tabhi to Chand Main Daag Hain


Kabhi To Ki Hogi Suraj Ne Chand Se Mohabbat
Tabhi to Chand Main Daag Hain
Shayed Ki Hogi Chand Ne Bewafai
Is Liye Suraj Main Aag Hai


Shayari : Raat hogi to chand bhi dikhai dega,

Raat hogi to chand bhi dikhai dega,
khabho me tumhe vo chehra bhi dikhai dega;
ye mohabat hai jara soch ke krna,
kyonki ik AANSU bhi gira to sunai dega.

waqt mohtaaz nahin manjilon ki,
waqt har manzil dikha deta hai,
marta nahin koi kisi se juda hokar,
waqt sab ko jina sikha deta hai.

Shayari : phir usi chand se rista bana baithe…

Kadam yun hi dagmga gaye raaste se,
warna sambhlna hum bhee jante the,
Thokar bhee lagi to us pathar se,
Jise hum Apna khuda mante the.

phir usi chand se rista bana baithe,
phir usi saadgi se fareb kha baithe,
pathron se tha taalukaat hamara,
phir bhee sheeshe ka ghar bna baithe

Shayari : Kya pyar ka izhar karna jaruri hai

Unhe Chahna hamari kamjori hai..
Unhe keh nahi pana hamari majburi hai..
Voh kyo nahi samjte hamari khamoshiya ko
Kya pyar ka izhar karna jaruri hai …….

Chahne se koi cheez apni nahi hoti,
har muskurahat khushi nahi hoti,
Kehna to Chahte hai bahot kuch magar,
kabhi alfaz to kabhi zuban sath nahi hoti
