Data transmission in communication system
First Claim
1. A method comprising:
- transmitting data in messages between a first system entity and at least one third system entity through a second system entity by using a transmission control protocol/internet protocol (TCP/IP) or a user datagram protocol/internet protocol (UDP/IP) transport protocol, wherein each message comprises a port number parameter indicating a transmission control protocol or user datagram protocol port number, respectively, andusing a modified port number parameter further indicating an identity of the at least one third system entity, to which and from which a message is transmitted, in the transmission of such as message between the first system entity and the second system entity,wherein the use of a modified port number parameter comprisesincluding, in the first system entity, the identity of the at least one third system entity to which a message is transmitted in the port number parameter of the message;
transmitting the message to the second system entity; and
removing, in the second system entity, the identity of the at least one third system entity from the port number parameter of the message before transmitting the message to the at least one third system entity.

Abstract
A method for transmitting data in a communications system and a communication arrangement comprising a first network entity (10) and a second network entity (20), the arrangement being configured to transmit data in messages between the first network entity (10) and one or more third network entities (41, 42, 43) through the second network entity (20) by using the TCP/IP or UDP/IP transport protocol, wherein each message comprises a port number parameter indicating a TCP or UDP port number, respectively, and to use a modified port number parameter further indicating an identity of the third network entity (41, 42, 43), to/from which a message is transmitted, in the transmission of such a message between the first network entity (10) and the second network entity (20).

10. A system, comprising:
-
a first network entity and a second network entity; wherein the system is configured to transmit data in messages between the first network entity and at least one third network entity through the second network entity by using a transmission control protocol/internet (TCP/IP) or a user datagram protocol/internet protocol (UDP/IP) transport protocol, wherein each message comprises a port number parameter indicating a transmission control protocol or user datagram protocol port number respectively; and wherein the system is further configured to use a modified port number parameter further indicating an identity of the at least one third network entity, to which and from which a message is transmitted, in the transmission of such a message between the first network entity and the second network entity, and wherein the first network entity is configured to include the identity of the at least one third network entity to which a message is transmitted in the port number parameter of the message when transmitting the message to the at least one third network entity through the second network entity, and the second network entity is configured to remove the identity of the at least one third network entity from the port number parameter of the message before forwarding the message to the at least one third network entity. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. An apparatus comprising:
-
a transmitter configured to transmit data in messages to at least one third system element through a second system element by using a transmission control protocol/internet protocol (TCP/IP) or a user datagram protocol/internet protocol (UDP/IP) transport protocol, wherein each message comprises a port number parameter indicating a transmission control protocol or user datagram protocol port number, respectively, wherein the apparatus is configured to include an identity of the at least one third system element, to which a message is transmitted, in the port number parameter of the message when transmitting the message to the at least one third system element through the second system element, wherein the identity of the at least one third system element comprises a physical address of the at least one third system element, wherein the physical address of the at least one third system element comprises one or both of an interface unit number and an interface port number of the second system element to which the at least one third system element is connected, and wherein the apparatus is configured to include the identity of the at least one third system element in the port number parameter of the message by re-calculating the port number parameter according to the following formula re-calculated port number parameter value=10000+protocol number*3000+interface unit number*100+interface port number, wherein protocol number=predefined protocol sequence number. - View Dependent Claims (20)
