Methods for dynamically assigning a multimedia broadcast/multicast service (MBMS) bearer to a Multicast Channel (MCH) in a communication network include a logical server: receiving a MBMS configuration for the communication network; receiving a request for a MBMS bearer within a service area, wherein the request specifies a QoS requirement for the MBMS bearer; inspecting the MBMS configuration to determine if an existing MCH in the service area meets the QoS requirement for the MBMS bearer; based on the inspecting, assigning the MBMS bearer to the existing MCH or assigning the MBMS bearer to a new MCH.

1. A method for dynamically assigning a multimedia broadcast/multicast service (MBMS) bearer to a Multicast Channel (MCH) in a communication network, the method comprising: at a logical server:receiving a MBMS configuration for the communication network;receiving, from a content provider, a request for a MBMS bearer within a service area, wherein the request specifies a QoS requirement for the MBMS bearer;inspecting the MBMS configuration to determine if an existing MCH in the service area meets the QoS requirement for the MBMS bearer;based on the inspecting, assigning the MBMS bearer to the existing MCH or assigning the MBMS bearer to a new MCH. 2. The method of claim 1, wherein assigning the MBMS bearer to the existing MCH comprises: determining that the existing MCH meets the QoS requirement for the MBMS bearer;determining that the existing MCH has sufficient bandwidth to support the MBMS bearer; andassigning the MBMS bearer to the existing MCH. 3. The method of claim 1, wherein assigning the MBMS bearer to the existing MCH comprises: determining that the existing MCH meets the QoS requirement for the MBMS bearer;determining that the existing MCH lacks sufficient bandwidth to support the MBMS bearer;reconfiguring the MBMS configuration to increase a number of frames that are assigned to the existing MCH; andassigning the MBMS bearer to the existing MCH. 4. The method of claim 1, wherein assigning the MBMS bearer to a new MCH comprises: determining at least one of: an inability of the existing MCH to meet the QoS requirement for the MBMS bearer; or an insufficient bandwidth of the existing MCH to support the MBMS bearer;reconfiguring the MBMS configuration to add the new MCH, wherein the new MCH meets the QoS requirement for the MBMS bearer; andassigning the MBMS bearer to the new MCH. 5. The method of claim 1, wherein the QoS requirement includes at least one of a latency specification and a jitter specification. 6. The method of claim 1 further comprising: inspecting the MBMS configuration to determine if the existing MCH covers the service area for the MBMS bearer;determining that the existing MCH does not cover the service area for the MBMS bearer; andassigning the MBMS bearer to the new MCH. 7. The method of claim 1, wherein Session Description Protocol is used to specify the QoS requirement for the MBMS bearer. 8. The method of claim 1 further comprising: interfacing to an operations and maintenance (O&M) system; andreceiving, from the O&M system, the MBMS configuration, wherein the MBMS configuration includes a list of available multicast channels, wherein the list provides a QoS specification for each of the available multicast channels, and wherein the list provides a service area specification for each of the available multicast channels. 9. The method of claim 1, wherein assigning the MBMS bearer to the existing MCH comprises: determining that a jitter specification for the requested MBMS bearer is more stringent than a jitter specification for another MBMS bearer assigned to the existing MCH; andin response to the determining that the jitter specification for the requested MBMS bearer is more stringent than the jitter specification for the other MBMS bearer, assigning the requested MBMS bearer to the existing MCH such that data for the requested MBMS bearer is transmitted before data for the other MBMS bearer. 10. The method of claim 1, wherein assigning the MBMS bearer comprises: interfacing to an operations and maintenance (O&M) system; andinstructing the O&M system to reconfigure the MBMS configuration. 11. The method of claim 1, assigning the MBMS bearer comprises: interfacing to a radio access network (RAN) element; andinstructing the RAN element to reconfigure the MBMS configuration. 12. The method of claim 1, wherein at least one base station within the service area is reconfigured to transmit the MBMS bearer on the existing MCH or the new MCH. 13. The method of claim 12, wherein the MBMS bearer uses a service identification (ID) and a session ID, and wherein the at least one base station within the service area is reconfigured to transmit the service ID and the session ID over a multicast control channel for the existing MCH or the new MCH. 14. The method of claim 1, wherein assigning the MBMS bearer to the existing MCH comprises: determining that the existing MCH meets the QoS requirement for the MBMS bearer;determining that the existing MCH lacks sufficient bandwidth to support the MBMS bearer; andmodifying the MBMS configuration such that existing MBMS bearers of lower priority are moved to a later position in a set of sub-frames than new or existing MBMS bearers of higher priority; andassigning the MBMS bearer to the existing MCH. 15. A method for dynamically allocating a multimedia broadcast/multicast service (MBMS) bearer having a QoS in a communication network including an MBMS configuration, the method comprising: at a content provider:initiating a MBMS session within a specified service area including a request for the MBMS bearer, the request comprising a specification for the QoS of the MBMS bearer;submitting the request to a logical server of a communication network for transmission, the submitting resulting in a change to the MBMS configuration and wherein the change in the MBMS configuration comprises a modification of an existing Multicast Channel (MCH) to meet the specification for the QoS of the MBMS bearer or a setting up of a new MCH that meets the specification for the QoS of the MBMS bearer;in response to the submitting, receiving an MBMS bearer identification corresponding to the changed MBMS configuration; andtransmitting a media stream on a MCH as specified by the MBMS bearer identification. 16. The method of claim 15, wherein the request comprises a session initiation protocol (SIP) INVITE method. 17. The method of claim 16, wherein the SIP INVITE method includes a SDP that is used to transmit the specification for the QoS of the MBMS bearer. 18. The method of claim 15, wherein the MBMS bearer identification includes at least one selected from the group consisting of: a service ID; and a session ID. 19. A system for assigning a multimedia broadcast/multicast service (MBMS) bearer to a Multicast Channel (MCH) in a communication network, the system comprising: a logical server having a processing device, network interface, and memory coupled together to:receive a MBMS configuration for the communication network;receive, from a content provider, a request for a MBMS bearer within a service area, wherein the request specifies a QoS requirement for the MBMS bearer;inspect the MBMS configuration to determine if an existing MCH in the service area meets the QoS requirement for the MBMS bearer;based on the inspecting, assign the MBMS bearer to the existing MCH or assigning the MBMS bearer to a new MCH. 20. The system of claim 19 further comprising: an operations and maintenance (O&M) system coupled to the network;wherein the O&M system transmits the MBMS configuration to the logical server; andwherein the logical server instructs the O&M system to reconfigure the MBMS configuration.
