IMS Based Network Stored Address Book using the XCAP Protocol


Aakanksha Aggarwal, H. Anthony Chan


Vol. 10  No. 9  pp. 119-126


The IP Multimedia Subsystem (IMS) network is the next generation network that aims to integrate all traditional circuit-switched networks into one network on which services can be accessed at any time and from any place. This paper highlights how the next generation networks evolve to IMS and explains different protocols such as SIP and XCAP. One of the main advantages of IMS is that it provides an environment for rapid service creation. In order to test whether applications can be created on the IMS platform rapidly, an application is designed and implemented on the IMS platform. Using the standardized available APIs, the application that is created in order to prove that IMS allows development of new services is a network stored address book. Theft is considered a large problem regarding cellular phones. Cellular phones are stolen or lost frequently and if a phone is stolen or lost, the user’s contacts are also lost. It is difficult to retrieve the contacts’ details once the phone is stolen or lost. Another problem is that if a user requires a particular contact’s details and does not have the mobile phone that contains the address book at that moment it is difficult to gain access to the contacts on the user’s cellular phone. This is considered a big problem since a user could require a contact’s details quite urgently and would not be able to get the details. The network stored address book created helps eliminate these problems.
