Abstract

A method for operating a first communications environment, wherein communications resources for communications according to a first communications standard are used for communications according to a second communications standard.

Claims

1-25. -25. (canceled)

26. A method for operating a first communications environment having a first communications standard and a second communications environment having a second communications standard, wherein resources for communications according to the first communications standard are used for communications according to the second communications standard within a common frequency range, the method comprising the steps of:

communicating in the first communications environment by transmitting a first frame structure in the common frequency range; and

communicating in the second communications environment by transmitting a second frame structure in the common frequency range;

wherein the first frame structure includes at least one transmission gap and at least a part of the second frame structure is transmitted during the at least one transmission gap.

27. The method according to claim 26, wherein the second communications environment is operated such that communications according to the second communications standard are at least partially performed in the first communications environment according to the first communications standard.

28. The method according to claim 26, further comprising the steps of:

communicating in the first communications environment by transmitting a plurality of subsequent first frames, at least one thereof including the at least one transmission gap; and

,

communicating in the second communications environment by transmitting a plurality of subsequent second frames.

29. The method according to claim 26, further comprising the steps of:

communicating in the first communications environment by transmitting a W-CDMA frame forming the first frame structure; and

,

communicating in the second communications environment by transmitting a TDMA frame forming the second frame structure.

30. The method of claim 28, wherein each of the first frames includes a number of first slots and the at least one transmission gap is defined on slot basis by a first predefined number of first slots;

and,

each of the second frames includes a number of second slots.

31. The method of claim 28, wherein the at least one transmission gap includes slots of one of the first frames;

and,

the at least one transmission gap includes slots of two consecutive ones of the first frames.

32. The method claim 28, wherein during the at least one transmission gap a second predefined number of the second slots or a second predefined number of the second frames is transmitted.

33. The method according to claim 26, further comprising the step of synchronizing communications in the first and second communications environments such that a frame timing for the first frame structure is synchronized with a frame timing for the second frame structure.

34. The method according to claim 26, further comprising the steps of:

defining the first frame structure such that the at least one transmission gap has a predefined position therein; and

,

defining the first frame structure such that the at least one transmission gap has a predefined length.

35. The method according to claim 26, wherein said part of the second frame structure transmitted during the transmission gap is used for communicating in the second communications environment.

36. The method according to claim 26, wherein the time interval between the beginning of one transmission gap and the beginning of a subsequent transmission gap corresponds to the time interval between the beginning of a part of the second frame structure to be transmitted during transmission gaps and the beginning of a subsequent part of the second frame structure to be transmitted during transmission gaps.

37. The method according to claim 26, further comprising the steps of:

transmitting timing information between the first and second communications environments to synchronize communications therein; and

,

transmitting information to the second communications environment indicating that communicating therein will be performed by transmissions in the common frequency range.

38. The method according to claim 26, wherein the first communications environment is an UMTS communications environment and the second communications environment is a GSM/GPRS communications environment.

39. A communications system, comprising:

a first communications environment having a first communications standard;

a second communications environment having a second communications standard; and

a common frequency range for communications in the first and second communications environments;

wherein the communications system is adapted to utilize, for communications in the common frequency range, resources for communications according to the first communications standard for communications according to the second communications standard;

the first communications environment comprising at least one first communications unit for transmitting a first frame structure in the common frequency range; and

,

the second communications environment comprising at least one second communications unit for transmitting a second frame structure in the common frequency range;

wherein the first fame structure includes at least one transmission gap; and

,

wherein the second communications unit transmits the second frame structure such that at least a part of the second frame structure is transmitted during the at least one transmission gap.

40. The communications system according to claim 39, further comprising at least one timing unit for synchronization of frame structure transmissions of the first communications unit and the second communications unit.

41. The communications system according to claim 39, wherein the first and second communications units form an integrated communications unit for servicing communications in the first and second communications environments.

42. The communications system according to claim 39, wherein the first communications environment is an UMTS environment and the second communications environment is a GSM/GPRS environment.
