Abstract

The invention relates to processing, at a transmitting entity, messages to be transferred between a transmitting entity and a receiving entity. The method comprises: obtaining a message to be transferred to the receiving entity, defining a substantially unique identifier at least for one part of the message to be transferred, conditionally replacing said part of the message to be transferred with said substantially unique identifier, and forwarding the message for transfer to the receiving entity. Further the invention relates to processing, at a receiving entity, messages transferred between a transmitting entity and a receiving entity The method comprises: receiving a message transferred from the transmitting entity, the message comprising a substantially unique identifier as a substitute of a part of the message, and retrieving said substituted part of the message on the basis of said substantially unique identifier

Claims

1-28. -28. (canceled)

29. A method for processing messages to be transferred between a transmitting entity and a receiving entity at least partially over a communication network, the method comprising the steps of

obtaining, to the transmitting entity, a message to be transferred to the receiving entity,

defining a substantially unique identifier at least for one part of the message to be transferred, a definition of the substantially unique identifier being based on the content of a part of the message,

replacing said part of the message with said substantially unique identifier in a condition that the part of the message is previously transferred to the receiving entity, and

forwarding the message for transfer to the receiving entity.

30. The method according to claim 29, wherein the method further comprises the step of

maintaining previous identifiers obtained for parts of previous messages transmitted to and associated with said receiving entity and information about the parts of the previous messages, and

wherein said step of replacing the part of the message is conducted responsive to comparing said substantially unique identifier to the previous identifiers.

31. The method according to claim 29, wherein said substantially unique identifier for said part of the message is a hash value or a cyclical checksum.

32. The method according to claim 29, wherein said substantially unique identifier for said part of the message comprises a difference between said part of the message and certain auxiliary data.

33. The method according to claim 32, wherein said substantially unique identifier for said part of the message further comprises an identifier for the certain auxiliary data.

34. The method according to claim 32, the method further comprising the step of selecting data, which is at least partially similar with said part of the message, to be used as the certain auxiliary data.

35. The method according to claim 32, the method further comprising the step of selecting data, which is likely to be available for the receiving entity, to be used as the certain auxiliary data.

36. The method according to claim 34, wherein said selection of the data is targeted to data stored in a cache.

37. The method according to claim 35, wherein said selection of the data is targeted to data stored in a cache.

38. The method according to claim 30, wherein said information about the parts of the previous messages comprises references to said parts stored in a memory.

39. The method according to claim 30, wherein said information about the parts of the previous messages comprises said parts.

40. The method according to claim 29, wherein said message is one of the following:

an e-mail, an MMS (Multimedia Messaging Service) message, a mobile Java game, or another downloadable content.

41. A method for processing messages transferred in a communication network between a transmitting entity and a receiving entity, the method comprising the steps of

receiving, at the receiving entity, a message transferred from the transmitting entity, the message comprising a substantially unique identifier as a substitute of a part of the message, the substantially unique identifier being defined on the basis of the content of the part of the message, and

retrieving said part of the message on the basis of said substantially unique identifier.

42. The method according to claim 41, the method further comprising the steps of

maintaining previous identifiers obtained for parts of previous messages transmitted from and associated with said transmitting entity and information about the parts of the previous messages, and before said step of retrieving the part of the message,

comparing said substantially unique identifier to the previous identifiers.

43. The method according to claim 42, wherein said step of retrieving the part of the message comprises a sub-step of

requesting said part of the message from the transmitting entity when said substantially unique identifier is missing from said previous identifiers.

44. The method according to claim 41, wherein said substantially unique identifier for said part of the message is a hash value or a cyclical checksum.

45. The method according to claim 41, wherein said substantially unique identifier for said part of the message comprises a difference between said part of the message and certain auxiliary data.

46. The method according to claim 45, wherein said substantially unique identifier for said part of the message further comprises an identifier for the certain auxiliary data.

47. The method according to claim 45, wherein said retrieving of said part of the message is conducted by retrieving the certain auxiliary data and by combining said difference with the certain auxiliary data.

48. The method according to claim 42, wherein said information about the parts of the previous messages comprises:

said parts or references to said parts stored in a memory.

49. The method according to claim 41, wherein said message is one of the following:

an e-mail, an MMS (Multimedia Messaging Service) message, a mobile Java game, or another downloadable content.

50. A transmitting entity (600) adapted for processing messages to be transferred between the transmitting entity and a receiving entity at least partially over a communication network, the transmitting entity comprising:

means (601, 602) for obtaining a message to be transferred to the receiving entity,

means (601, 602) for defining a substantially unique identifier at least for one part of the message to be transferred, the substantially unique identifier being defined on the basis of the content of a part of the message,

means (601, 602) for replacing said part of the message with said substantially unique identifier in a condition that the part of the message is previously transferred to the receiving entity, and

means (601, 602) for forwarding the message for transfer to the receiving entity.

51. A receiving entity for processing messages transferred between a transmitting entity and the receiving entity at least partially over a communication network, the receiving entity comprising:

means for receiving a message transferred from the transmitting entity, the message comprising a substantially unique identifier as a substitute of a part of the message, a definition of the substantially unique identifier being based on the content of the part of the message, and

means for retrieving said part of the message on the basis of said substantially unique identifier.

52. A system comprising a transmitting entity and a receiving entity, said system being adapted to transmit messages between the transmitting and receiving entities at least partially over a communication network,

the transmitting entity comprising:

means for obtaining a message to be transferred to the receiving entity,

means for defining a substantially unique identifier at least for one part of the message to be transferred, a definition of the substantially unique identifier being based on the content of a part of the message,
