Common mobility management protocol for multimedia applications, systems and services
First Claim
1. A computer processing device or data server that facilitates communication between a first multimedia application and a second multimedia application, the computer processing device or data server comprising:
- a common mobility management protocol shared by the first and second multimedia applications, the common mobility management protocol further comprising;
an address template for defining a set of address identifiers and profile information for completing a communication between the first multimedia application to the second multimedia application; and
a descriptor for carrying address information, the descriptor comprising a unique identifier for the descriptor that includes a time the descriptor last changed, at least one address template having a template life field and a functional entity identifier indicating an associated functional entity of the descriptor, and wherein the common mobility management protocol further comprises a visitor location function and a home location function.

Abstract
A framework of a common mobility management protocol for Q.5/16 (Mobility for Multimedia Systems/Applications and Services) comprises a high level protocol for performing the functions of address resolution, routing, location update and authentication. The common mobility management protocol can be used by all existent and future multimedia applications (MA'"'"'s) to support mobility management for messaging among mobility management authentication function (AuF), home location function (HLF) and visitor location function (VLF) databases/servers, and the corresponding multimedia application functional entities (MAFEs) of the multimedia applications (MA'"'"'s). The common mobility management protocol may replace, act in concert with or in sequence with existent interworking protocols for the various multimedia applications. Reference point architectures, functional characteristics, features, and capabilities of the protocol are described including call flows and message syntax. In addition, the scope of Q.5/16 and how H.MMS.1 (H.323 Mobility), H.MMS.2 (Global Mobility), and H.MMS.3 (Presence/Instant Messaging Mobility) can be a part of the same common mobility management protocol have also been presented.

14. A method performed by a computer processing device for messaging between a first application and a second application according to a common mobility management protocol, the method comprising:
-
receiving a descriptor request message at a descriptor owning functional entity, the descriptor comprising a unique identifier for the descriptor that includes a time the descriptor last changed, at least one address template having a template life field and a functional entity identifier indicating an associated functional entity of the descriptor; matching the descriptor request message with a plurality of templates; and transmitting a descriptor confirmation message with all matching templates, wherein the descriptor comprises a group of at least one template, the template defining one of a set of at least one address identifier and service profile data, and wherein the common mobility management protocol further comprises a visitor location function and a home location function. - View Dependent Claims (15, 16)
