Abstract

A method is provided to activate a packet data protocol (PDP) context in a cellular network. This may include determining whether users associated with the cellular network may receive multicast or broadcast data and activating the PDP context based on the determination. The determination may be based on a trigger that occurs when a notification is sent to the Serving GPRS Support Node (SGSN). The SGSN may get notified based on a periodic status query, an update message and/or an activation request, for example.

Claims

1. A method to activate a packet data protocol (PDP) context in a cellular network comprising:

determining whether users associated with said cellular network may receive one of multicast data and broadcast data; and

activating said PDP context based on said determination.

2. The method of claim 1, wherein said activating said PDP context is performed by a Serving GPRS Support Node (SGSN).

3. The method of claim 2, further comprising maintaining a database on said SGSN related to user information.

4. The method of claim 3, further comprising updating said database on said SGSN.

5. The method of claim 1, wherein said activating said PDP context is performed by said network.

6. The method of claim 1, wherein said activation is transparent to user equipment.

7. The method of claim 1, wherein said activating said PDP context comprises utilizing a Radio Network Controller (RNC) to indicate a status of user cells.

8. The method of claim 1, wherein said determining is based on a trigger, wherein said trigger occurs when a notification is sent to a Serving GPRS Support Node (SGSN).

9. The method of claim 8, wherein said SGSN gets notified of a status of one of multicast service and broadcast service based on a periodic status query.

10. The method of claim 8, wherein said SGSN gets notified of a status of one of multicast service and broadcast service based on an update message.

11. The method of claim 8, wherein said SGSN gets notified of a status of one of multicast service and broadcast service based on an activation request.

12. The method of claim 8, wherein said SGSN gets notified of a new address for one of multicast service and broadcast service.

13. The method of claim 8, wherein said SGSN gets notified of a new identification of one of multicast service and broadcast service.

14. The method of claim 1, further comprising creating Gateway Tunneling Protocol tunnels following said activation.

15. A method comprising activating a packet data protocol (PDP) context in a cellular network by determining whether users may receive one of multicast data and broadcast data.

16. The method of claim 15, wherein said activating said PDP context is performed by a Serving GPRS Support Node (SGSN).

17. The method of claim 16, further comprising maintaining a database on said SGSN relating to user information.

18. The method of claim 17, further comprising updating said database on said SGSN.

19. The method of claim 15, wherein said activating said PDP context is performed by said network.

20. The method of claim 15, wherein said activation is transparent to user equipment.

21. The method of claim 15, wherein said determining is based on a trigger, wherein said trigger occurs when a notification is sent to a Serving GPRS Support Node (SGSN).

22. The method of claim 21, wherein said SGSN gets notified of a status of one of multicast service and broadcast service based on a periodic status query.

23. The method of claim 21, wherein said SGSN gets notified of a status of one of multicast service and broadcast service based on an update message.

24. The method of claim 21, wherein said SGSN gets notified of a status of one of multicast service and broadcast service based on an activation request.

25. The method of claim 21, wherein said SGSN gets notified of a new address for one of multicast service and broadcast service.

26. The method of claim 21, wherein said SGSN gets notified of a new identification of one of multicast service and broadcast service.

27. The method of claim 15, further comprising creating Gateway Tunneling Protocol tunnels following said activation.

28. A system for performing a transmission in a cellular network, said system comprising a core network to activate a packet data protocol context with users associated with said cellular network.

29. The system of claim 28, wherein said core network comprises a node to maintain a database related to user information.

30. The system of claim 29, wherein said core network comprises a Serving GPRS Support Node (SGSN).

31. The system of claim 30, wherein said activation is based on a trigger, wherein said trigger occurs when a notification is sent to said SGSN.

32. The system of claim 31, wherein said SGSN gets notified of a status of one of multicast service and broadcast service based on a periodic status query.

33. The system of claim 31, wherein said SGSN gets notified of a status of one of multicast service and broadcast service based on an update message.

34. The system of claim 31, wherein said SGSN gets notified of a status of one of multicast service and broadcast service based on an activation request.

35. The system of claim 31, wherein said SGSN gets notified of a new address for one of multicast service and broadcast service.

36. The system of claim 31, wherein said SGSN gets notified of a new identification of one of multicast service and broadcast service.

37. The system of claim 28, wherein said core network node activates said packet data protocol by determining whether there are users in a radio access network and determining whether said users are allowed to receive one of multicast data and broadcast data.

38. The system of claim 28, wherein said core network transmits data using a point-to-point connection based on a number of user equipment being below a predetermined number.

39. The system of claim 38, wherein said number of user equipment is obtained by paging user equipment using identification that identifies a service.

40. The system of claim 39, wherein said number of user equipment is further obtained by said user equipment sending user equipment identification as a response.
