Presence Server
The Wireless ZT Presence Server integrates directly into the IMS architecture as detailed by 3GPP, but can also be used outside of the IMS domain. The Wireless ZT IMPS will also comply with the Presence server requirements as they are defined by OMA-PAG.
The Wireless ZT Presence Server supports a modular Network Presence Agent. The modules can receive network presence information from various network components such as HSS/HLR, S-CSCF, MSC/VLR, SGSN, GGSN, and MLC.
It is also possible to implement other network presence modules and plug these in, so that presence information can be retrieved from other network elements, such as portal platforms.
For messaging applications in general, there is a powerful presence advantage that makes the conversation more rational. In a short amount of time, perhaps communicating without checking the available presence information will be like entering your boss's office without knocking!
The Wireless ZT IM and Presence Server also contains powerful presence interfaces and APIs, which can be used to share presence information between several applications in addition to messaging. Typical telecom services such as push-to-talk, multi player games and voice-mail services are enhanced by presence information.
The Wireless ZT IM and Presence Server is a powerful service enabler for next-generation presence enabled services.
