Abstract

A method and system of managing group calls includes receiving first and second call control signaling at a user communication entity. The user communication entity determines that the first call control signaling is associated with a first delivery method and in response thereto configures the user communication entity to receive first call data that is associated with the first call control signaling. The user communication entity determines that the second call control signaling is associated with a second delivery method. In response to determining that the second call control signaling is associated with the second delivery method, a priority associated with the second call control signaling is determined and, according to the priority associated with the second call control signaling, the user communication entity is configured to receive second call data associated with the second call control signaling.

Claims

1. A method for managing group calls, the method comprising:

receiving, at a user communication entity, first call control signaling associated with a first group of user communication entities, wherein the user communication entity is one user communication entity of the first group of user communication entities;

determining, at the user communication entity, that the first call control signaling is associated with a first delivery method;

in response to determining that the first call control signaling is associated with the first delivery method, configuring the user communication entity to receive first call data associated with the first call control signaling;

receiving, at the user communication entity, second call control signaling associated with a second group of user communication entities, wherein the user communication entity is one user communication entity of the second group of user communication entities;

determining, at the user communication entity, that the second call control signaling is associated with a second delivery method; and

in response to determining that the second call control signaling is associated with the second delivery method;

determining a priority associated with the second call control signaling; and

configuring the user communication entity to receive second call data associated with the second call control signaling, according to the priority associated with the second call control signaling.

2. The method of claim 1, wherein determining that the first call control signaling is associated with a first delivery method comprises one of:

determining that media associated with the first call control signaling is configured to be delivered by the first delivery method; and

determining that the first call control signaling was received by the first delivery method.

3. The method of claim 1, further comprising:

configuring the user communication entity to receive first call data associated with the first call control signaling by the first delivery method.

4. The method of claim 1, further comprising:

determining that the priority associated with the second call control signaling is greater than a priority associated with the first call control signaling.

5. The method of claim 1, further comprising:

configuring the user communication entity to stop receiving the first call data associated with the first call control signaling when the priority associated with the second call control signaling is greater than the priority associated with the first call data.

6. The method of claim 1, further comprising:

maintaining, at the user communication entity, a list of active calls of the user communication entity; and

determining that a priority associated with the first call data is lower than priorities of all call control signaling of all calls in the list of active calls.

7. The method of claim 1, wherein the first delivery method is a unicast delivery method and the second delivery method is a broadcast delivery method.

8. The method of claim 1, wherein the second delivery method is an evolved Multimedia Broadcast Multicast Service (eMBMS) delivery method.

9. The method of claim 1, wherein the first delivery method and the second delivery method are on different networks.

10. The method of claim 1, further comprising:

maintaining a scan list including a plurality of group identifiers, wherein each of the plurality of group identifiers is associated with a priority; and

configuring the user communication entity to receive call data associated with one or more group call identifiers of the plurality of group call identifiers according to priorities of the one or more group call identifiers and an availability of call data associated with the one or more group call identifiers.

11. The method of claim 10, further comprising:

sending the scan list to a call controller.

12. The method of claim 1, further comprising:

receiving, at the user communication entity, a background update including background call control signaling;

determining a priority associated with the background call control signaling; and

configuring the user communication entity to receive call data associated with the background call control signaling, according to the priority associated with the background call control signaling.

13. The method of claim 12, wherein the background update is sent using non real-time messaging.

14. The method of claim 1, further comprising:

configuring the user communication entity to operate in an idle mode of the first network when the user communication entity is not actively receiving data on the first network.

15. A system for managing group calls, the system comprising:

a first data interface, for receiving data by a first delivery method;

a second data interface, for receiving data by a second delivery method;

a processor coupled to the first data interface and the second data interface; and

a memory coupled to the processor, the memory including instruction code executable by the processor for;

receiving, first call control signaling associated with a first group of user communication entities;

determining that the first call control signaling is associated with the first delivery method;

in response to determining that the first call control signaling is associated with the first delivery method, configuring the user communication entity to receive first call data associated with the first call control signaling;

receiving second call control signaling associated with a second group of user communication entities;

determining that the second call control signaling is associated with a second delivery method; and

in response to determining that the second call control signaling is associated with the second delivery method;

determining a priority associated with the second call control signaling; and

configuring the user communication entity to receive second call data associated with the second call control signaling, according to the priority associated with the second call control signaling.

16. The system of claim 15, wherein the first data interface comprises a data interface for receiving data from a first data network and the second data interface comprises a data interface for receiving data from a second data network.

17. A user communication entity comprising:

receiver circuitry for receiving data by each of a first delivery method and a second delivery method;

a processor coupled to the receiver circuitry; and

a memory coupled to the processor, the memory including instruction code executable by the processor for;

receiving, first call control signaling associated with a first group of user communication entities;

determining that the first call control signaling is associated with the first delivery method;

in response to determining that the first call control signaling is associated with the first delivery method, configuring the user communication entity to receive first call data associated with the first call control signaling;

receiving second call control signaling associated with a second group of user communication entities;

determining that the second call control signaling is associated with a second delivery method; and

in response to determining that the second call control signaling is associated with the second delivery method;

determining a priority associated with the second call control signaling; and

configuring the user communication entity to receive second call data associated with the second call control signaling, according to the priority associated with the second call control signaling.

18. The user communication entity of claim 17, wherein the user communication entity is a user equipment.

19. The user communication entity of claim 17, wherein the user communication entity is a mobile radio.
