Abstract
Abstract A cellular system supports dispatch and datagram operations. The architecture of a conventional cellular system, such as the GSM system, is modified by adding a local area network (TIL) where nodes on the network include various base switching controllers (BSC). The BSC has a Switching Interface Module (SIM) which provides an interface to the TIL. The TIL may also include one or more gateways (40) to landline based networks. The datagram operation uses an appropriate gateway to complete a data path which includes an RF segment to or from the BSC. Dispatch operations provide for switching by the BSC so that switching is at a level below the Mobile Switching Center (MSC). For example, compressed voice traffic received by the BSC may be transmitted over the TIL to another BSC from where it is sent over an RF segment to a mobile receiver (MS).

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
96 words
A cellular mobile telephone system for connecting mobile telephone stations with telephone terminals connected in a public switched telephone network, said system comprising a plurality of stations each with an interface to said mobile stations, at least one mobile switching center, said mobile switching center including an interface to said public switched telephone network and an interface to said plurality of stations, and communication means for communicating messages from one station to at least a not her station, said communication means including a local area network wherein said stations are nodes of said local area network.
Claim 2
Dependent Claim
96 words
A cellular mobile telephone system for connecting mobile telephone stations with telephone terminals connected in a public switched telephone network, said system comprising a plurality of stations each with an interface to said mobile stations, at least one mobile switching center, said mobile switching center including an interface to said public switched telephone network and an interface to said plurality of stations, and communication means for communicating messages from one station to at least a not her station, said communication means including a local area network wherein said stations are nodes of said local area network.
Claim 3
Dependent Claim
35 words
A system as recited in claim 1 wherein at least one of said stations include a radio frequency interface to said mobile stations which operates exclusively within one cell of said cellular mobile telephone system.
Claim 4
Dependent Claim
63 words
A system as recited in claim 1 which further includes at least one radio frequency station, each said radio frequency station having a radio frequency interface to said mobile stations for operating exclusively within a region of said cellular mobile telephone system, and a station interface to at least one station, said station interface including means for transmitting and receiving compressed voice traffic.
Claim 5
Dependent Claim
64 words
A system as recited in claim 2 wherein: said stations include means to compress voice traffic from said public switched telephone network for transmission to said mobile stations and means to expand compressed voice traffic from said mobile stations for transmission to said public switched telephone network, and wherein said stations include an interface for transmitting compressed voice traffic onto said local area network.
Claim 6
Dependent Claim
24 words
A system as recited in claim 2 in which said stations include an interface for transmitting compressed voice traffic onto said local area network.
Claim 7
Dependent Claim
24 words
A system as recited in claim 1 which further includes a gateway coupled to said communication link with an interface to a data network.
Claim 8
Dependent Claim
49 words
A system as recited in claim 2 in which said stations include an interface to said local area network, said interface including means for monitoring messages on said local area network and means for copying those messages addressed to a mobile station registered with the station of the interface.
Claim 9
Dependent Claim
64 words
A system as recited in claim 3 wherein: said stations include means to compress voice traffic from said public switched telephone network for transmission to said mobile stations and means to expand compressed voice traffic from said mobile stations for transmission to said public switched telephone network, and wherein said stations include an interface for transmitting compressed voice traffic onto said local area network.
Claim 10
Dependent Claim
24 words
A system as recited in claim 3 in which said stations include an interface for transmitting compressed voice traffic onto said local area network.
Claim 11
Dependent Claim
49 words
A system as recited in claim 3 in which said stations include an interface to said local area network, said interface including means for monitoring messages on said local area network and means for copying those messages addressed to a mobile station registered with the station of the interface.
Claim 12
Independent Claim
118 words
A method of providing dispatch operations in a cellular telephone system comprising the steps of: a) registering a mobile at a station, b) initiating a dispatch setup by transmitting, to a given station, an identification of those mobile stations to be included in a dispatch pool from a dispatch initiator, c) registering, in the given station an identification for the pool along with the identification of those mobile stations to be included in the dispatch pool, d) initiating a message for transmission to members of the pool by transmitting voice traffic to the given station from the dispatch initiator, e) transmitting a message related to the voice traffic over a traffic interconnection local area network to other stations.
Claim 13
Independent Claim
118 words
A method of providing dispatch operations in a cellular telephone system comprising the steps of: a) registering a mobile at a station, b) initiating a dispatch setup by transmitting, to a given station, an identification of those mobile stations to be included in a dispatch pool from a dispatch initiator, c) registering, in the given station an identification for the pool along with the identification of those mobile stations to be included in the dispatch pool, d) initiating a message for transmission to members of the pool by transmitting voice traffic to the given station from the dispatch initiator, e) transmitting a message related to the voice traffic over a traffic interconnection local area network to other stations.
Claim 14
Dependent Claim
35 words
A method as recited in claim 11 including the further steps of: f) at a station other than the given station, copying said message for transmission to the mobile station registered with the other station.
