Dynamic switching of streaming service between broadcast and unicast delivery
Various communication systems may benefit from a dynamic streaming service. For example, certain streaming services may benefit from an improvement in the switching between broadcast delivery and unicast delivery for a streaming service in a cellular system. A method includes receiving information about a streaming service. The method also includes determining by a network entity in a radio access network whether to deliver data for the streaming service via multimedia broadcast or unicast based on the information and predetermined criteria for evaluating the information. In addition, the method includes triggering a sending of the data via the multimedia broadcast or the unicast.
1. A method, comprising:
receiving information about a streaming service;
determining, by a network entity in a radio access network, whether to deliver data for the streaming service via multimedia broadcast or unicast based on the information and predetermined criteria for evaluating the information, wherein the predetermined criteria comprises at least one distribution of a plurality of user equipment in at least one multimedia broadcast multicast single frequency network (MBSFN) area on at least one cell level in the radio access network associated with an average number of user equipment per cell in the at least one MBSFN area; and
triggering a sending of the data via the multimedia broadcast or the unicast, the method further comprising:
comparing the average number of user equipment per cell with a first predetermined threshold to choose a delivery method to deliver data for the streaming service based on a comparison result where there is a user equipment associated with multimedia broadcast multicast services service in each cell that is part of the MBSFN area, and
comparing the average number of user equipment per cell with a second predetermined threshold to choose a delivery method to deliver data for the streaming service based on a comparison result where there are first cells that have no user equipment interested in multimedia broadcast multicast services service and second cells that have a plurality of user equipment that are associated with multimedia broadcast multicast services.
2. The method according to claim 1 , further comprising:
triggering a switching between a multimedia broadcast to a unicast, or between a unicast to a multicast broadcast, based on the information and the predetermined criteria for evaluating the information.
3. The method according to claim 1 , further comprising:
suspending multicast traffic channels, when switching between a multimedia broadcast to a unicast based on the information and the predetermined criteria for evaluating the information.
4. The method according to claim 1 , wherein the predetermined criteria further comprises one or more of at least one size of the broadcast area of the network and a number of the plurality of user equipment connected to a radio resource control in each of a plurality of cells of the broadcast area.
5. The method according to claim 1 , wherein the streaming service is delivered over a multicast user plane connection between a gateway and a base station in the radio access network, independent of whether content is being delivered via multimedia broadcast or unicast radio.
6. The method according to claim 5 , wherein the triggering a sending of the data via multimedia broadcast or unicast occurs on the user plane connection.
7. The method according to claim 1 , further comprising:
scheduling at least one resource for multimedia broadcast to at least one user equipment.
8. The method according to claim 1 , wherein the information about the streaming service is drawn from at least one of a multimedia broadcast or multicast service counting procedure, multimedia broadcast or multicast service interest indication, consolidated multimedia broadcast or multicast service consumption report, and resource availability of the radio access network.
9. The method according to claim 1 , wherein the multimedia broadcast comprises a multicast service including a single cell point to multipoint or a multimedia broadcast single frequency network.
10. The method according to claim 1 , wherein the network entity comprises a multi-cell or multicast coordination entity.
11. The method according to claim 1 , wherein the information about the streaming service is received from another network entity, a streaming service provider, or the radio access network.
12. The method according to claim 1 , wherein the unicast comprises a unicast bearer that is established without a corresponding evolved packet system bearer, and wherein no traffic flow template is needed on either side of the unicast bearer.
13. An apparatus, comprising:
at least one memory comprising computer program code; and
at least one processor,
wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to:
receive information about a streaming service;
determine whether to deliver data for the streaming service via multimedia broadcast or unicast based on the information and predetermined criteria for evaluating the information, wherein the predetermined criteria comprises at least one distribution of a plurality of user equipment in at least one multimedia broadcast multicast single frequency network (MBSFN) area on at least one cell level in the radio access network associated with an average number of user equipment per cell in the at least one MBSFN area; and
trigger a sending of the data via the multimedia broadcast or the unicast, wherein the at least one memory and the computer program code are further configured, with the at least one processor, to cause the apparatus at least to:
compare the average number of user equipment per cell with a first predetermined threshold to choose a delivery method to deliver data for the streaming service based on a comparison result where there is a user equipment associated with multimedia broadcast multicast services service in each cell that is part of the MBSFN area, and
compare the average number of user equipment per cell with a second predetermined threshold to choose a delivery method to deliver data for the streaming service based on a comparison result where there are first cells that have no user equipment interested in multimedia broadcast multicast services service and second cells that have a plurality of user equipment that are associated with multimedia broadcast multicast services.
14. The apparatus according to claim 13 , wherein the at least one memory and the computer program code are further configured, with the at least one processor, to cause the apparatus at least to:
trigger a switching between a multimedia broadcast to a unicast, or between a unicast and a multimedia broadcast, based on the information and the predetermined criteria for evaluating the information.
15. The apparatus according to claim 13 , wherein the predetermined criteria further comprises one or more of at least one size of the broadcast area of the network and a number of the plurality of user equipment connected to a radio resource control in each of a plurality of cells in the broadcast area.
16. The apparatus according to claim 13 , wherein the streaming service is delivered over a multicast user plane connection between a gateway and a base station in the radio access network, independent of whether content is being delivered via multimedia broadcast or unicast radio.
17. The apparatus according to claim 13 , wherein the triggering a sending of the data via multimedia broadcast or unicast occurs on the user plane connection.
18. The apparatus according to claim 13 , wherein the at least one memory and the computer program code are further configured, with the at least one processor, to cause the apparatus at least to:
schedule at least one resource for multimedia broadcast to at least one user equipment.
19. The apparatus according to claim 13 , wherein the information about the streaming service is drawn from at least one of a multimedia broadcast or multicast service counting procedure, multimedia broadcast or multicast service interest indication, consolidated multimedia broadcast or multicast service consumption report, and resource availability of the radio access network.
