## Abstract

A method includes receiving a request for a communication session from a user device, identifying a first resource from a plurality of resources, wherein the first resource is associated with a first service control layer for a radio access network and wherein the plurality of resources includes at least one virtual network function (VNF), identifying a second resource from the plurality of resources, wherein the second resource is associated with a second service control layer for LTE core functions, identifying a third resource from the plurality of resources, wherein the third resource is associated with a third service control layer for content delivery, allocating a virtual machine to be used to instantiate the at least one VNF, instantiating the at least one VNF and establishing the communication session by facilitating communications between the first service control layer, the second service control layer and the third service control layer.

## Claims

### Claim 1

A device, comprising:
a processing system including a processor; and
a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
receiving a request for content in a content network having a content service control layer, wherein the request prompts for the content to be broadcast to a user device;
identifying a type of content associated with the request;
determining an encoding scheme to utilize for broadcast of the content;
coordinating communication between the content service control layer, a network core service control layer, and an access network service control layer, wherein the coordinating involves identifying core physical network functions (PNFs) and core virtual network functions (VNFs);
instantiating the core PNFs and the core VNFs to provide resources for content broadcasting; and
broadcasting the content to the user device and causing the network core service control layer to synchronize mobility of the user device with the core PNFs and core VNFs during the broadcasting.

### Claim 2 (depends on 1)

The device of claim 1, wherein the processing system comprises a master service orchestration layer.

### Claim 3 (depends on 1)

The device of claim 1, wherein the access network service control layer comprises a radio access network (RAN) service control layer.

### Claim 4 (depends on 1)

### Claim 5 (depends on 1)

The device of claim 1, wherein the coordinating is performed on a per service chain or per application basis.

### Claim 6 (depends on 1)

The device of claim 1, wherein the coordinating involves preparing the content for the broadcasting.

### Claim 7 (depends on 6)

The device of claim 6, wherein the preparing is performed based on available network capacity, user demand, service offering, subscription, geographic location, or a combination thereof.

### Claim 8 (depends on 1)

The device of claim 1, wherein the receiving comprises receiving the request from an application service layer.

### Claim 9 (depends on 8)

The device of claim 8, wherein the operations further comprise receiving, from the application service layer, performance metrics associated with the request.

### Claim 15

A method comprising:
receiving a request for content from a content network having a content service control layer, wherein the request prompts for the content to be broadcast to a one or more end user devices;
determining a type of content associated with the request;
selecting an encoding scheme for broadcast of the content;
coordinating communication between the content service control layer, a network core service control layer, and an access network service control layer, wherein the coordinating involves identifying core physical network functions (PNFs) and core virtual network functions (VNFs);
