Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
47 words
An interworking apparatus for roaming among a plurality of mobile networks having different inter-network signaling protocols, said apparatus connected to said plurality of mobile networks comprising: means for holding network identity information for identifying a mobile network visited by at least a mobile user to be traced.
Claim 2
Dependent Claim
33 words
The apparatus as claimed in claim 1, wherein said apparatus further comprises means for holding location area identity information for identifying a location area of the mobile user in the visited mobile network.
Claim 3
Dependent Claim
155 words
An interworking apparatus for roaming among a plurality of mobile networks having different inter-network signaling protocols, said plurality of mobile networks including a first mobile network having a first inter-network signaling protocol which uses a subscriber number PM1 for identifying a subscriber and a terminal identity TM1 for identifying a terminal, and a second mobile network having a second inter-network signaling protocol which is different from said first inter-network signaling protocol and uses a terminal identity TM2 for identifying a terminal, said apparatus connected to said first and second mobile networks comprising: subscriber number storage means for holding the subscriber number PM1; and means for storing the terminal identity TM2 of a mobile user visiting from said second mobile network to said first mobile network into said subscriber number storage means, said visiting mobile user being traced in said first mobile network by using said terminal identity TM2 stored in said subscriber number storage means.
Claim 4
Dependent Claim
24 words
The apparatus as claimed in claim 3, wherein said apparatus further comprises means for holding network identity information for identifying the visited mobile network.
Claim 5
Dependent Claim
33 words
The apparatus as claimed in claim 3, wherein said apparatus further comprises means for holding location area identity information for identifying a location area of the mobile user in the visited mobile network.
Claim 6
Dependent Claim
204 words
An interworking apparatus for roaming among a plurality of mobile networks having different inter-network signaling protocols, said plurality of mobile networks including a second mobile network having a second inter-network signaling protocol which uses a subscriber number PM2 for identifying a subscriber and a terminal identity TM2 for identifying a terminal, and a third mobile network having a third inter-network signaling protocol which is different from said second inter-network signaling protocol and uses a subscriber number PM3 for identifying a subscriber and a terminal identity TM3 for identifying a terminal, said apparatus connected to said second and third mobile networks comprising: subscriber number storage means for holding the subscriber number PM3; terminal identity storage means for holding the terminal identity TM3; means for storing the subscriber number PM2 of a mobile user visiting from said second mobile network to said third mobile network into said subscriber number storage means; and means for storing the terminal identity TM2 of said visiting mobile user into said terminal identity storage means, said visiting mobile user being traced in said third mobile network by using said subscriber number PM2 stored in said subscriber number storage means and said terminal identity TM2 stored in said terminal identity storage means.
Claim 7
Dependent Claim
24 words
The apparatus as claimed in claim 6, wherein said apparatus further comprises means for holding network identity information for identifying the visited mobile network.
Claim 8
Dependent Claim
33 words
The apparatus as claimed in claim 6, wherein said apparatus further comprises means for holding location area identity information for identifying a location area of the mobile user in the visited mobile network.
