Methods and systems are provided such that users, servers, and applications may utilize an extensible data filtering model where data is organized into a tree with filtering available at any node level. Accordingly, the node filtering and propagation method and system allows for the efficient management and automatic replication of common information for multiple applications at all data levels.

Method, apparatus, and system for providing and using subscriptions and filtering based on tree structures

The embodiments presented herein provide an automated process for provisioning a user in a communication system. A session manager, which can be a server in the communication system that provides call connection and routing, may receive registration request from communication device (e.g. a cellular telephone, an IP-enabled phone, etc.). The session manager may determine one or more characteristics about the communication device and/or determine a load on one or more other session managers in a cluster of session managers. Based on both the communication device characteristics and/or the loads on the two or more session managers, the session manager can determine a set of session managers, which may include a primary session manager and a secondary session manager, which can manage the user data for the communication device. This session manager set information may then be sent to the communication device and to other session managers in the cluster. The set of session managers may then manage the user data for the communication device.

Automatic user redundancy determination

Methods and systems for providing an elegant and efficient multi-protocol eventing layer are disclosed. The multi-protocol eventing layer includes a converged container capable of handling multiple types of protocols to manage events while using an open source database. Accordingly, the multi-protocol eventing layer efficiently provides real-time or near real-time eventing to a plurality of devices for scalability and performance enhancement.

Method, apparatus, and system for providing and using multi-protocol eventing

The present disclosure describes methods and systems for managing resources, for example in connection with call admission control or other communications or transactions in a system. In particular, a plurality of resource pools are established. At least a first or priority resource is associated with a minimum resource amount, while at least a second or normal resource pool is associated with a maximum resource amount. From the system resource pools, allocations are made to each of a plurality of system servers. If a server receives a request for priority resources that cannot be satisfied from the allocation of priority resources made to that server, that server may borrow from an allocation of normal resources. Resources can also be shared between servers. Accordingly, if required resources are not available from an allocation made to a server receiving the request for resources, that server can request resources from another server. In responding to a request to share resources, a server can attempt to fill the request as if the request had originally been made to that server.

Resource allocation using shared resource pools

A distributed call control system is provided that can allot bandwidth amongst several call controllers. The distributed call control system includes one or more servers that execute two or more instances of call processing servers that administer call control. The call processing servers form a cluster or group. The cluster members negotiate and determine bandwidth allocation amongst the members. If a member requires more bandwidth, the call processing server, of that member, assesses its own needs and requests more bandwidth from other members. The negotiation and requests for bandwidth are accomplished with a set of dynamic and static bandwidth data that regiment the control of the bandwidth.
