Communications method and apparatus, database information retrieval method and apparatus
First Claim
1. A method, in a Universal Mobile Telecommunications System (UMTS) communications network, of establishing a communications session between first and second devices associated with first and second parties respectively, the method comprising:
- sending a session request message from the first device to a Session Initiation Protocol (SIP) proxy server indicating a request to establish the session and comprising session information relating to the session;
in response to the session request message, the SIP proxy server retrieving extended caller information and including the extended caller information in the session request message, the extended caller information being summary information, from which complete information can subsequently be determined by the second device, in a first database, synchronized with a related complete information in a second database for which the second device is registered, the complete information being stored in the first database and the summary information, derived from the complete information, being stored in the second database;
synchronizing the summary information in the second database with the complete information in the first database,retrieving summary information from the second database for inclusion in the extended caller information to enable the subsequent retrieval of complete information from the first database relating to the summary information from the second database;
the SIP proxy server sending the session request message to the second device; and
establishing the communications session based on the session information and the extended caller information in the resulting session request message.

Abstract
A method is provided of establishing a communications session between first and second devices associated with first and second parties respectively. A session request message indicates a request to establish the session and comprises session information. In response to the session request message, further information is retrieved and included in the session request message. A session is established based on information in the resulting session request message. The session may be established between the first and second devices using Session Initiation Protocol (SIP). Summary information is included for determining complete information by the second device after the session has been established. The complete information is stored in a mail server and the summary information derived from the complete information is stored in a database. The summary information is retrieved from the database for inclusion in the further information so as to enable the second device subsequently to retrieve complete information from the mail server relating to that summary information.

19. A method for use in a Universal Mobile Telecommunications System (UMTS) communications network associated with first and second devices the method comprising:
-
the first device sending a session request message to a Session Initiation Protocol (SIP) proxy server indicating a request to establish a communications session between the first and second devices, the session request message comprising session information relating to the session in a first database, synchronized with a related complete information in a second database for which the second device is registered, the SIP proxy server retrieving extended caller information in response to the session request message and including the extended caller information in the session request message, the extended caller information being summary information, from which complete information can subsequently be determined by the second device, in a first database, synchronized with a related complete information in a second database for which the second device is registered, the complete information being stored in the first database and the summary information, derived from the complete information, being stored in the second database; synchronizing the summary information in the second database with the complete information in the first database, retrieving summary information from the second database for inclusion in the extended caller information to enable the subsequent retrieval of complete information from the first database relating to the summary information from the second database; the SIP proxy server sending the session request message to the second device, in a first database, synchronized with a related complete information in a second database, for which the second device is registered; and establishing the session based on information in the resulting session request message.
