Abstract
Abstract A protocol converter for a wireless telecommunications system, the protocol converter comprising: an interface for receiving first protocol message packets from at least one control station of the telecommunications system and for transmitting first protocol message packets to the at least one control station; and a server in communication with the interface for maintaining the protocol converter and an object based telecommunications system control system; wherein the protocol converter converts first protocol message packets received from the interface into operations and converts operations into first protocol message packets for subsequent transmission to the at least one control station via the interface, the operations being received from and applied to the object based control system maintained in the server thereby to control the wireless telecommunications system.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
145 words
A protocol converter for a wireless telecommunications system, the protocol converter comprising: an interface for receiving a message packet of a first protocol from at least one control station of the telecommunications system and for transmitting a first protocol return packet to the at least one control station; and a server in communication with the interface for maintaining an object based control structure of the wireless telecommunications system; means for converting the first protocol message packet received from the interface into an operation to be applied to an object of the object based control structure, and for converting an operation into the first protocol return packet for subsequent transmission to the at least one control station via the interface, the operation being received from and applied to objects of the object based control structure maintained in the server thereby to control the wireless telecommunications system.
Claim 2
Dependent Claim
145 words
A protocol converter for a wireless telecommunications system, the protocol converter comprising: an interface for receiving a message packet of a first protocol from at least one control station of the telecommunications system and for transmitting a first protocol return packet to the at least one control station; and a server in communication with the interface for maintaining an object based control structure of the wireless telecommunications system; means for converting the first protocol message packet received from the interface into an operation to be applied to an object of the object based control structure, and for converting an operation into the first protocol return packet for subsequent transmission to the at least one control station via the interface, the operation being received from and applied to objects of the object based control structure maintained in the server thereby to control the wireless telecommunications system.
Claim 3
Dependent Claim
14 words
A protocol converter according to claim 1, wherein said converter has a multi-layer structure.
Claim 4
Dependent Claim
19 words
A protocol converter according to claim 2, wherein a first layer of the multi-layer structure is a line interface.
Claim 5
Dependent Claim
31 words
A protocol converter according to claim 3, wherein a second layer is a data link layer for transferring bytes of the first protocol message packets to and from the first layer.
Claim 6
Dependent Claim
48 words
A protocol converter according to claim 4, wherein a third layer is a network layer for establishing connections between an object in the server and a lower layer or an object in the server and a higher layer, and for authenticating the identity of first protocol message packets.
Claim 7
Dependent Claim
81 words
A protocol converter according to claim 5, wherein a fourth layer is a transport level, the transport level being provided for: (a) constructing frames of data from lower layer first protocol message packets and detecting and correcting errors in those lower layer message packets, or for (b) destructuring frames of data received from a higher layer into first protocol message packets, detecting and correcting errors in those first protocol message packets and transmitting those corrected message packets to the lower layer.
Claim 8
Dependent Claim
44 words
A protocol converter according to claim 6, wherein a sixth layer is a presentation layer for encoding lower layer first protocol message packets into at least one operation, and for decoding at least one operation from a higher layer into first protocol message packets.
Claim 9
Dependent Claim
38 words
A protocol converter according to claim 7, wherein a seventh layer is an application layer for receiving and outputting the at least one operation from a lower layer and/or for receiving at least one operation from the server.
Claim 10
Dependent Claim
34 words
A protocol converter according to claim 3, further comprising a management layer for supervising operation of the protocol converter and for managing errors outside of the scope of individual layers of the protocol converter.
Claim 11
Dependent Claim
17 words
A protocol converter according to claim 1, wherein said first protocol is a sub-system management protocol (SMP).
Claim 12
Dependent Claim
13 words
A protocol converter according to claim 1, wherein said operations are fully reversible.
Claim 13
Dependent Claim
45 words
A protocol converter according to claim 11 wherein the operation includes an "update" operation to update a state of the object to which the operation is applied or a "retrieve" operation to retrieve a current state of the object to which the operation is applied.
