  • System and method for allowing virtual private network users to obtain presence status and/or location of others on demand
    Patent number: 8804928
    Abstract: A system and method can support a virtual private network based on a public telecommunication infrastructure. The virtual private network can receive a request from a caller for place a call to a callee via the virtual private network. The virtual private network can obtain at least one of presence status and location information of the callee. Then, the virtual private network can allow the caller to make a decision on whether or not to proceed with the call. The public telecommunication infrastructure can be based on a legacy network and an Internet Protocol Multimedia Subsystem (IMS) network, and the virtual private network can obtain information from both the legacy network and the IMS network via a service broker.
