Abstract
Abstract This invention relates w a method of data transfer via a radio telephone network between a LAN ( 1 ) and a Mobile Station and to a data interface unit that applies the method. According to the method the LAN's data packets are formed, and the RLP control is stripped away from them, in the LAN-controller that is permanent connected to it; the data is packed into date packets in accordance with a data communications protocol and the data communications data packets are inserted into data frames of the radio telephone network when the data is transferred between the radio telephone units. The data interface unit ( 15 ) according to the invention is connected to a LAN-controller ( 14 ) on the side of the LAN ( 1 ). The data interface unit ( 15 ) incorporates a digital radio telephone unit ( 168 ) and a data adapter ( 17 ) for inserting the LAN's date packets into date frames and for extracting the data packets from these data frames when the data is transferred between the LAN and a Mobile Station that is connected to the digital radio telephone network.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
146 words
A method of transferring information directly to and from a local area network (LAN) using a radio telephone network, comprising the steps of: transferring a LAN information packet to an adapter that is connected to said LAN, said information packet having a first structure, said first structure including a data portion and a control portion; said first structure being predetermined for use in said LAN; stripping said control portion of said information packet and extracting said data from said packet; converting said extracted data into a second data structure that is predefined for use by said radio telephone network; transferring the data in said second data structure to a first radio telephone that is coupled to the radio telephone network; and transmitting said converted data to a base station of the radio telephone network, using said first radio telephone, for reception by a second radio telephone.
Claim 2
Independent Claim
146 words
A method of transferring information directly to and from a local area network (LAN) using a radio telephone network, comprising the steps of: transferring a LAN information packet to an adapter that is connected to said LAN, said information packet having a first structure, said first structure including a data portion and a control portion; said first structure being predetermined for use in said LAN; stripping said control portion of said information packet and extracting said data from said packet; converting said extracted data into a second data structure that is predefined for use by said radio telephone network; transferring the data in said second data structure to a first radio telephone that is coupled to the radio telephone network; and transmitting said converted data to a base station of the radio telephone network, using said first radio telephone, for reception by a second radio telephone.
Claim 3
Dependent Claim
23 words
A method according to claim 1 , wherein said second structure is a radio link protocol data frame for the radio telephone network.
Claim 4
Dependent Claim
25 words
A method according to claim 2 , wherein said data frames of the second structure are data frames of a time-divided digital radio telephone network.
Claim 5
Dependent Claim
21 words
A method according to claim 1 , wherein said second data structure is configured in accordance with a data communications protocol.
Claim 6
Dependent Claim
53 words
A method according to claim 1 , wherein the second data structure is formed by means of flags, the first flag of which is set at the start of the data to indicate the start of the data, the second flag being added to the end to indicate the end of the data.
Claim 7
Dependent Claim
99 words
A method of transferring information directly to and from a local area network (LAN) using a radio telephone network, as described in claim 1 , further comprising the steps of: receiving an information packet in said adapter having said second data structure via said first radio telephone; stripping a control portion, predefined for use by said radio telephone network, and extracting data from said received information packet in said adapter; converting said extracted data into said first data structure predefined for use by the LAN, and outputting said received information packet to the LAN in said first data structure.
Claim 8
Dependent Claim
21 words
A method according to claim 6 , wherein the second data structure comprises a data frame from the radio telephone network.
Claim 9
Dependent Claim
25 words
A method according to claim 7 , wherein data frames of the second data structure are data frames of a time-divided digital radio telephone network.
Claim 10
Dependent Claim
58 words
A method according to claim 6 , wherein the second data structure of the radio telephone network is formed by means of flags, the first flag of which is set at the start of the data to indicate the start of the data, the second flag being added to the end to indicate the end of the data.
Claim 11
Dependent Claim
204 words
A data transfer device for direct data transfer between a local area network (LAN) and a radio telephone network, said device comprising: a LAN controller connected to said LAN for processing information packets from the LAN having a first data structure, including a data portion and a control portion, said first structure being predetermined for use in said LAN; a radio telephone bidirectionally coupled to said radio telephone network for transmitting and receiving information packets having a second structure, including a data portion and a control portion, said second structure predefined for use by said radio telephone network; an adapter connected to said LAN controller and coupled to said radio telephone, said adapter constructed to strip said control portion of said information packet and to extract said data portion from said packet, and further to convert said data portion to said second structure for transmission by said radio telephone within said radio telephone network; and wherein said adapter is further constructed to receive information packets from said radio telephone having said second structure, to strip said control portion of said second structure and extract said data portion, and further to convert said data portion to said first structure for processing by said LAN controller.
Claim 12
Dependent Claim
204 words
A data transfer device for direct data transfer between a local area network (LAN) and a radio telephone network, said device comprising: a LAN controller connected to said LAN for processing information packets from the LAN having a first data structure, including a data portion and a control portion, said first structure being predetermined for use in said LAN; a radio telephone bidirectionally coupled to said radio telephone network for transmitting and receiving information packets having a second structure, including a data portion and a control portion, said second structure predefined for use by said radio telephone network; an adapter connected to said LAN controller and coupled to said radio telephone, said adapter constructed to strip said control portion of said information packet and to extract said data portion from said packet, and further to convert said data portion to said second structure for transmission by said radio telephone within said radio telephone network; and wherein said adapter is further constructed to receive information packets from said radio telephone having said second structure, to strip said control portion of said second structure and extract said data portion, and further to convert said data portion to said first structure for processing by said LAN controller.
