OBS! ANSÖKNINGSTIDEN FÖR DETTA EXJOBB HAR LÖPT UT.
Description of company

The thesis work will be carried out within the group for IMS, IP Multimedia Subsysten, within the Ericsson R&D organisation. One of the central nodes in IMS is the CSCF, Call Session Control Function. IMS with CSCF is the base for Ericsson´s multimedia solutions for fixed and mobile networks.

Background

LDAP (Lightweight Directory Access Protocol) is the protocol of choice for Configuration management of the CSCF node. Standard LDAP browsers are used as user interface towards the node. The limited graphical properties of the LDAP browser can be sufficient for simple data structures but comes short where more complex configuration data is concerned.

Job description

This proposed thesis shall investigate alternatives for presenting configuration data in a graphical user interface that is easy to understand and configure. Some tables are complex and interdependent and need intuitive user interface to configure and present. Some may contain regular expression that need to be expanded and presented in a way that is easy to understand.

The thesis shall result in a prototype developed in Java to provide platform independence and facilitate possible future integrations. The thesis should further consider different ways of interaction between the prototype and the CSCF node.

Competence

Knowledge in Java GUI programming and regular expressions. Knowledge in the LDAP protocol is desirable.
