The method includes monitoring unmanaged OTT streams flow in the cellular network; determining if at least one of the monitored unmanaged OTT streams can be delivered as an OTT stream in a multicast format; reformatting the at least one unmanaged OTT stream into a multicast OTT stream, if the at least one unmanaged OTT stream can be delivered in a multicast format; and delivering the at least one unmanaged OTT stream as a multicast OTT stream to a user edge device over the cellular network. ## Claims ### Claim 1 A method for delivery of unmanaged over-the-top (OTT) streams in a cellular network, comprising: monitoring unmanaged OTT streams flow in the cellular network; determining if at least one of the monitored unmanaged OTT streams can be delivered as an OTT stream in a multicast format; reformatting the at least one unmanaged OTT stream into a multicast OTT stream, if the at least one unmanaged OTT stream can be delivered in a multicast format; and delivering the at least one unmanaged OTT stream as a multicast OTT stream to a user edge device over the cellular network. ### Claim 2 (depends on 1) The method of claim 1, further comprising: provisioning multicast resources in the cellular network to deliver the multicast OTT stream to a user edge device; and provisioning multicast resources in the user edge device to receive and play the multicast OTT stream over the user edge device. ### Claim 3 (depends on 1) The method of claim 1, wherein the at least one unmanaged OTT stream is in a unicast format and is not controlled by an operator of the cellular network. ### Claim 4 (depends on 1) The method of claim 1, wherein determining if at least one of the monitored unmanaged OTT streams can be delivered as an OTT stream in a multicast format further comprising: determining a popularity of the at least one of the unmanaged OTT streams; determining a type of the at least one of the unmanaged OTT streams; and determining information related to an availability of multicast resources in the cellular network. ### Claim 5 (depends on 4) The method of claim 4, wherein a type of an unmanaged OTT stream that can be delivered as an OTT stream in a multicast format is any one of: a live OTT stream, a linear OTT stream, and a replicated OTT stream. ### Claim 6 (depends on 4) The method of claim 4, wherein the at least one of the unmanaged OTT streams is determined to be popular when a number of requests to the at least one unmanaged OTT stream exceeds a predefined threshold. ### Claim 7 (depends on 4) The method of claim 4, wherein the information related to the availability of multicast resources in the cellular network is at least one of: a number of available multicast channels, and an available bandwidth for each channel. ### Claim 8 (depends on 4) The method of claim 4, wherein determining if the at least one of the unmanaged OTT streams can be delivered as an OTT stream in a multicast format is based on at least one of: the type of the at least one unmanaged OTT stream, the popularity of the at least one unmanaged OTT stream, and the availability of the multicast resources. ### Claim 9 (depends on 1) The method of claim 1, wherein reformatting the at least one unmanaged OTT stream into a multicast OTT stream is performed on at least one of: an application layer, and a transport layer. ### Claim 10 (depends on 1) A non-transitory computer readable medium having stored thereon instructions for causing one or more processing units to execute the method according to claim 1. ### Claim 11 A system for delivery of unmanaged over-the-top (OTT) streams in a cellular network, comprising: a processing unit; and a memory, the memory containing instructions that, when executed by the processing unit, configure the system to: monitor a request for unmanaged OTT streams flow in the cellular network; determine if at least one of the unmanaged OTT streams can be delivered as an OTT stream in a multicast format; reformat the at least one unmanaged OTT stream into a multicast OTT stream, if the unmanaged OTT stream can be delivered in a multicast format; and deliver the at least one unmanaged OTT stream as a multicast OTT stream to a user edge device over the cellular network. ### Claim 12 (depends on 11) The system of claim 11, wherein the system is further configured to: provision multicast resources in the cellular network to deliver the multicast OTT stream to a user edge device; and provision multicast resources in the user edge device to receive and play the multicast OTT stream over the user edge device. ### Claim 13 (depends on 11) The system of claim 11, wherein the at least one unmanaged OTT stream is in a unicast format and is not controlled by an operator of the cellular network. ### Claim 14 (depends on 11) The system of claim 11, wherein the system is further configured to: determine a popularity of the at least one of the unmanaged OTT streams; determine a type of the at least one of the unmanaged OTT streams; and determine information related to an availability of multicast resources in the cellular network. ### Claim 15 (depends on 14) The system of claim 14, wherein a type of an unmanaged OTT stream that can be delivered as an OTT stream in a multicast format is any one of: a live OTT stream, a linear OTT stream, and a replicated OTT stream. ### Claim 16 (depends on 14) The system of claim 14, wherein the at least one of the unmanaged OTT streams is determined to be popular when a number of requests to the at least one unmanaged OTT stream exceed a predefined threshold. ### Claim 17 (depends on 14) The system of claim 14, wherein the information related to the availability of multicast resources in the cellular network is at least one of: a number of available multicast channels, and an available bandwidth for each of the multicast channels. ### Claim 18 (depends on 14) The system of claim 14, wherein determining if the at least one of the unmanaged OTT streams can be delivered as an OTT stream in a multicast format is based on at least one of: the type of the at least one unmanaged OTT stream, the popularity of the at least one unmanaged OTT stream, and the availability of the multicast resources. ### Claim 19 (depends on 11) The system of claim 11, wherein the system is further configured to: reformat the at least one unmanaged OTT stream into a multicast OTT stream on at least one of: an application layer, and a transport layer. ### Claim 20 (depends on 11) The system of claim 11, wherein the multicast resources in the cellular network comprise a multimedia broadcast multicast service (MBMS) network and the multicast resources in the user edge device comprise at least a MBMS middleware. ### Claim 21 A method for delivery of managed over-the-top (OTT) streams in a cellular network, comprising: receiving an indication that a managed OTT stream is delivered by an operator of the cellular network; provisioning, in real time, multicast resources in the cellular network to deliver the managed OTT stream to a user edge device; and provisioning, in real time, multicast resources in the user edge device to play the managed OTT stream over the user edge device.
