Using a Radio Access Network (RAN) capacity exchange (or RANxChange), mobile operators can advertise slices/partitions of available unused base station capacity, and auction and lease it. A member-operator can advertise their unused base station capacity availability or lease capacity from another member-operator for a specific time period. The bidding operators can bid for the full auctioned capacity or portion of the auctioned capacity. The users start attaching the leased slice transparently without any configuration changes on their mobile devices.

System and method for a RAN exchange

A novel system and a new data communication method are invented in a software-defined (SDN) network to provide delivery of certain types of critical data flows with certain QoS and/or extra security requirements in a congested network. The method of invention allows such critical data not to traverse the data plane, as it normally would, but instead to go from the ingress switch directly to the egress switch, thereby always in two hops using the control channels. By shortcutting all other switches along the traditional data path computed by normal routing, it potentially provides guaranteed throughput, lower latency/jitter or higher level of security.

A special data splitter and data combiner is shown for low latency emergency and data intensive services so that multiple broadband and wireless networks can be utilized along with public safety networks. Any data session, multimedia or non-multimedia, is split into multiple packet streams with each stream having an identifier wherein some packet streams are sent via the secure public safety network and other streams are sent via other networks of varying characteristics and performance, and a combiner at the other end receiving multiple streams from different networks combines them into a single session.

Enabling split sessions across hybrid public safety and LTE networks

Sensitive data is sent through insecure network regions across different software defined networks (SDNs) over an encrypted path without requiring encryption applications at the source or destination hosts. One or more special-purpose encryptors are strategically placed within each SDN, which can act as an encryptor or decryptor, of both the data packet content and the header. Using the controller and a special encryption service application, the encrypted IP packets are forwarded from an encryptor, closest to the source, towards a decryptor, closest to the destination, utilizing a tagging method. Each encryptor has a static and globally unique tag. Each controller advertises to other controllers its encryptor information: IP of the encryptor, the IP block of the users the encryptor is responsible for and the unique encryptor tag(s). Each forwarder along the flow path is instructed by its respective controller how to forward packets towards the destination according to the tag.

A system and method that rely on a centralized and trusted control mechanism for a software-defined network (SDN) to dynamically assign routes between two end points, and to simultaneously change their real IP addresses to fake IP addresses to establish short-lived obfuscated communications paths with a goal of preserving anonymity. The SDN controller determines the short-lived routes from a feasible route-set and new fake IP addresses from a reserved address pool for the source and destination hosts. It provisions only the switches along the route with rules so that a switch can forward packets of the data flow to another switch without needing to know the actual IP addresses of the communicating endpoints, and hence, providing strict anonymity even when the switches are compromised.

A method to check health of automatically discovered controllers comprises the steps of: (a) a first controller generating a first Controller-Advertisement message carrying the information required to identify and access the first controller when a new switch port becomes active; (b) the first controller sending the generated first Controller-Advertisement to a first switch having the newly activated port; (c) the first controller receiving at least a second Controller-Advertisement message from at least a second controller; (d) the first controller generating a third unsolicited Controller-Advertisement message with its access information to check health of the second controller; (e) the first controller receiving at least a fourth Controller-Advertisement message from the second controller indicating health information of the second controller, wherein the health information is stored in first controller's Controller Information Base (CIB).

This invention is an apparatus an methods which integrates users' avatars into IP-based calling and messaging telecommunication services in such a way that avatar can be animated in real-time according to spoken words, anticipated gestures and pre-set and stored emotions. The invention includes an online editor to generate and customize users avatars.

Controllers in a Software Defined Network (SDN) automatically discover and authenticate each other as part of the control plane operations, without any need for manual configuration of other controllers. The new capability of such controllers is based on Controller-Advertisement messages transferred between controllers in the same or different SDNs. In doing so, multiple controllers can be used for load sharing, improved reliability under failure of a controller by enabling seamless take over and recovery. Moreover, controllers can cooperate to enable end-to-end services to work across multiple SDNs. Controller-Advertisement messages are also used to check the health statuses of discovered controllers in the same or different SDNs.

A method and system are provided to schedule the transmissions to a plurality of applications for a plurality of users connected to a femtocell taking into account the quality of service (QoS) requirements of each application served while maintaining an efficient use of the wireless radio resources as well as a user and application weighted notion of fairness of service reception. The scheduler differentiates between not only different users but also between applications of each user, and schedules data transmission amongst these applications so that QoS requirements for all applications are satisfied.

A system and method for an on-line web-based advertiser-broker to subsidize calls of a plurality of VOIP operators' subscribers by showing them video advertisements from a catalogue of advertisements provided by a plurality of advertisers. The advertisement is shown by the advertiser-broker and then the call is transferred to the VoIP operator for call completion. The advertiser-broker provides the clearing-house services between many advertisers and many VoIP operators, subsidizing wholly or partially phone calls of users of VoIP operators by showing them streaming video advertisements of advertisers who pay for the calls. With this new business, phone calls get monetized through advertisers while users pay nothing for phone calls, and VoIP operators do not need to incorporate advertisers to their business.
