Fruit Soup , Haricot Bean Soup & Lentil Soup

Fruit Soup:

Ingredients:

• Apples-1 lb.
• Water-1 qt.
• Sugar and flavouring
• Sago-1 tablespoon

Method:

• Wash the apples and cut into quarters, but do not peel or core.
• Place it into a pan with the water and sugar and flavouring to taste.
• When sweet, ripe apples can be obtained,people with natural tastes will prefer no addition of any kind.
• If u prefer u can add little cinnamon, cloves, or the yellow part of lemon rind.
• Stew until the apples are soft.
• Strain through a sieve, rubbing the apple pulp through, but leaving cores, etc.,
  behind.
• Wash the sago and add it to the strained soup and boil gently for 1 hour.
• Stir now and then, as the sago is apt to stick to the pan.

Haricot Bean Soup:

Ingredients:

• Beans-2 Cups
• Water-2 qts
• Chopped parsley-3 tablespoons
• Tomatoes, nut or dairy butter size of walnut- ½ lb.
• Lemon juice-1 tablespoon .

Method:

• For this soup u have to use the small white or brown haricots.
• Soak the haricots overnight in 1 qt. of the water.
• In the morning add the rest of the water and boil until it become soft.
• Then rub through a sieve, but this is not essential.
• Add the chopped parsley and the lemon juice and the butter.
• Boil up and serve.
• You can add tomato pulp to flavour soup as substitute of parsley, just skin the tomatoes and stew to pulp(should not add water) before adding.
  

Lentil Soup:

Ingredients:

• Lentils-4 breakfast-cups
• Carrot-1
• Turnip-1
• Onions-2
• Water-4qts
• Celery-4 sticks
• Herb powder-2 teaspoons
• Lemon juice-1 tablespoon
• Butter-1 oz.

Method:

• You can use red or Egyptian lentils, or the green German lentils for this soup.
  
• If you use latter one, soak it in water overnight itself.
• Stew the lentils very gently in the water for 2 hours, taking off any scum that rises.
• Well wash the vegetables, slice them, and add to the soup.
• Again Stew it for 2 hours more.
• Then u may either rub through a sieve or not, as preferred.
• Add the lemon juice, herb powder and butter (nut or dairy) and serve it.

GPRS SYSTEM DESCRIPTION

GPRS Overview

• The GPRS system brings the packet switched bearer services to the existing GSM system.
  
• In the GPRS system a user can access the public data networks, like the Internet or corporate intranets by a GPRS mobile station.
  
• Connections are established directly using the standard protocol addresses of the external networks (IP, X.25).
• The GPRS MS can use between one to eight channels over the air-interface depending on the MS type and the GSM traffic at the same time.
  
• The GPRS traffic uses the same air interface channels as GSM, and those channels are dynamically allocated to a GPRS MS when there are packets to be sent or received.
• In the GPRS network, uplink and downlink channels are reserved separately making it possible to have multi slot MSs with various uplink and downlink capabilities.
  
• The resource allocation in the GPRS network is dynamic and dependent on the demand and resource availability. Packets can also be sent on idle time between speech calls, which results in more efficient utilization of the air interface traffic channels.
  
• With the GPRS system it is possible to communicate point-to-point (GPRS Phase1) or point-to-multipoint (GPRS Phase2), and the GPRS system also supports the SMS and Anonymous Access to the network.
  
• Theoretically, the maximum throughput in the GPRS system can be 171,2 Kbit/s per MS using all eight channels without error correction

Short Message Service via GPRS

Data Flow Through GPRS Network

• A logical communication pipe is established between GGSN and MS through a SGSN (Figure 3.11). LLC protocol link is established between MS and the SGSN upon GPRS attach. GPRS Tunnel Protocol (GTP) established a tunnel between SGSN and GGSN at PDP context activation.
• The LLC frames are exchanged between MS and SGSN. In the LLC header, the NSAPI (Network layer Service Access Point Identifier) identifies which application inside the MS the packet belongs to.

• There can be various tunnels between SGSN and GGSN.
  
• The GGSN knows the address of the SGSN handling a given mobile and the SGSN knows the addresses of all the GGSNs that have an active routing context for this user. In the GTP header, the TID (Tunnel Identifier) identify the routing context at the other end of the tunnel.

Short Message Service via GPRS:

• In the GPRS system the SMS can be delivered to MS via two different routes.
• The short message service center (SM-SC) forwards the Short Message first to an SMS-GMSC, which examines the destination MS address, and queries HLR about the current location of the destination MS.
  
• The response may contain the MS's current SGSN number, the MSC number, or both. If the result does not contain an SGSN Number (i.e., the HLR knows that the MS is not reachable via an SGSN), and if the result contains a MSC number, then the SMS-GMSC forwards the SM to the MSC (Route B in the below Figure), which transfers the SM to the MS.
• If the result contains an SGSN number, the SMS-GMSC forwards the SM to the SGSN (Route A in the below Figure), that transfers the SM to the MS. The SMS delivery via the SGSN is more radio resource efficient than delivery via the MSC/VLR. The preferred delivery path is selected by SMS-GMSC operator-specific action.
