generating by means of the packet data interface apparatus charging messages indicative of the usage of the packet data communication services by the first terminal; and

transferring the charging messages to a charging apparatus;

the method further including the steps of;

transferring the charging arrangement information stored at the subscriber information store from the subscriber information store to the packet data interface apparatus; and

storing at the packet data interface apparatus the charging arrangement information received from the subscriber information store for the first communication terminal; and

wherein the step of generating charging messages comprises generating the said charging messages dependent on the charging arrangement information for the first communication terminal.

30. A method as claimed in claim 29, wherein a charging operation to attribute to a subscriber for the first communications terminal a charge for use of the communication services by the first terminal is performed by means of the charging apparatus.

31. A method as claimed in claim 29, wherein the step of generating the usage information messages comprises:

determining on the basis of the charging arrangement information for the first communication terminal stored at the packet data interface apparatus whether a communication with the first communication terminal is liable to charging; and

generating a charging message for the communication if the communication is liable to charging.

32. A method as claimed in claim 30, wherein it is determined that a communication is not liable for charging if charging arrangement information for the first communication terminal stored at the packet data interface apparatus indicates that the communication is subject to flat rate payment.

33. A method as claimed in claim 30, wherein it is determined that a communication is not liable for charging if charging arrangement information for the first communication terminal stored at the packet data interface apparatus indicates that the communication is subject to pre-payment.

34. A method as claimed in claim 30, wherein it is determined that a communication is not liable for charging if charging arrangement information for the first communication terminal stored at the packet data interface apparatus indicates that the communication is free of charge.

35. A method as claimed in claim 30 wherein it is determined that a communication is not liable for charging if a session itself indicates that the communication is free of charge.

36. A method as claimed in claim 29 wherein the charging message is indicative of the duration and/or type of the communication.

37. A method as claimed in claim 29 wherein the charging message is indicative of an amount of data transferred in the communication.

38. A method as claimed in claim 29 wherein the charging message is indicative of the identity of the first communication terminal.

39. A method as claimed in claim 29 wherein the charging message is a CDR ticket.

40. A method as claimed in claim 29 wherein the step of transferring the charging arrangement information to the packet data interface apparatus is performed during attachment of the first communication terminal to the telecommunications system.

41. A method as claimed in claim 29 wherein the subscriber information store is a home location register.

42. A method as claimed in claim 40 wherein the home location register stores information indicative of access point names available to the first terminal, and the method includes the step of accessing that information.

43. A method as claimed in claim 29 wherein the packet data interface apparatus is capable of interfacing between a packet radio connection with the first communication terminal and a packet-switched data link to the other communications terminal.
