A method and a system for supporting rendezvous based instant group conferencing among mobile users allows a conference originator to initiate and setup instant group conferencing to a set of participants even when the participants may not be immediately available to commit to the conference call at the time of its initiation. All negotiations for obtaining commitments from the participants are performed by the system, thus relieving the originator of the time consuming task of negotiating with the participants. The system automatically decides as to when to actually dial out to the participants to setup the conference call after obtaining commitment from all (or a quorum of) required participants.

A method and a system are disclosed for making available telecommunication network resources associated with network subscribers and exposed by a Network Service Gateway (NSG) to clients of the NSG services based on stored subscriber availability preferences. The method and system can be implemented using an availability Policy Server that sits next to or inside of the NSG. The Policy Server interprets the stored availability preferences of subscribers in response to requests for subscriber information. These availability preferences are translated into a low-level policy rule language. The Policy Server implements a policy rule evaluator to evaluate policies written in this language. Policies written in the low-level language are referred to as aPolicies (availability policies). An aPolicy receives as input a stream of events. Based on these events, the aPolicy may decide to take one or more actions.

A method and a system are disclosed for obtaining the dynamic network state of mobile subscribers, such as subscriber location, presence or other state information. This information, which may be distributed within various core mobile network elements, is obtained via a differentiated network service gateway (DNSG) that interfaces with the mobile network elements in a manner that accommodates the network's operator enforced controls and limitations. The DNSG implements service level agreements (SLAs) that support differentiated quality-of-service (QoS) in terms of accessing the dynamic network state of the mobile subscribers. The consumers (DNSG clients) of the dynamic network state information may include applications that provide communication and transactional services to mobile subscribers based on their network state, and the mobile subscribers themselves. The consumers register with the DNSG for SLAs to obtain a desired QoS that determines the precision and speed at which the network service functions for their exclusive use. The DNSG uses the SLAs to allocate available resources to the consumers and for scheduling queries to the core network elements so as to obtain the network state of the mobile subscribers according to the requirements of the SLAs.
