The purpose of this research  is to evaluate the performance of integrated UMTS and  WLAN network by using two types of standard  integrated models proposed by 3GPP,open coupling and  loose coupling together with network layer mobility  management scheme such as Mobile IP.In this research  we  calculate the different application¿s traffic our  concluded results shows that page response time is  smaller for loose coupling scheme as compare to open  coupling scheme although difference is not so much  wide, pageresponse time increases with the passage of  time because number of users increases as the time  passes. Same is In case for FTP, download response  time for FTP is smaller in case of loose coupling  scheme. We have also calculated the WLAN performance  parameters (delay and throughput) and UMTS downlink  traffic sent and received. We have discussed in  detail architecture and functionalities of UMTS and  WLAN, mobile IP, standard interworked UMTS and WLAN  models proposed by 3GPP.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838371740\"\u003e\u003ch3\u003eINTEGRATION OF HETEROGENEOUS WIRELESS NETWORKS\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838371740","offer_id":39499098751069,"sku":"9783838371740","price":59.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/29241408-1aa7-44b8-9c56-ab48329e50cc.jpg?v=1770790677","url":"https:\/\/shop.autorenwelt.de\/products\/performance-evaluation-of-vertical-handover-between-umts-and-wlan-von-syed-amjad-iqbal-und-muhammad-ahmad","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
