Either the first party or the second party initiates a call with the other party. One of a set of call splitters distributed through the plurality of telecommunications networks is then determined to be a local call splitter to one of the parties. A connection is then established between the first party and the local call splitter to split the call into a recording part and a call part. The call part is routed between the first party and the second party via the call splitter to provide transmission of media between the first party and the second party, and the recording part is provided by the local call splitter to a recording service associated with the first party. Suitable apparatus is also described, as are methods for recording the calls of a subscriber to a central recording station using a network trigger set or a SIM application set to divert the call to a recording node. ## Claims ### Claim 1 A method of recording media transmitted to or from a first party communicating through one of a plurality of mobile telecommunications networks with a second party, the method comprising: either the first party or the second party initiating a call with the other party; determining one of a set of call splitters distributed through the plurality of telecommunications networks to be a local call splitter to the first or the second party; establishing a connection between the first party and the local call splitter to split the call into a recording part and a call part, wherein the call part is routed between the first party and the second party via the call splitter to provide transmission of media between the first party and the second party, and wherein the recording part is provided by the local call splitter to a recording service associated with the first party. ### Claim 2 (depends on 1) A method as claimed in claim 1, wherein the transmitted media comprises a voice call. ### Claim 3 (depends on 1) A method as claimed in claim 1, wherein determining one of a set of call splitters to be a local call splitter is carried out by a service node of a home mobile telecommunications network for the first party. ### Claim 4 (depends on 3) A method as claimed in claim 3, wherein the home mobile telecommunications network notifies the local call splitter by intelligent network signalling. ### Claim 5 (depends on 4) A method as claimed in claim 4, wherein the home mobile telecommunications network is a GSM network and the intelligent network signalling comprises CAMEL messages. ### Claim 6 (depends on 1) A method as claimed in claim 1, wherein determining one of a set of call splitters to be a local call splitter is carried out by a SIM of a mobile communication device of the first party. ### Claim 7 (depends on 6) A method as claimed in claim 6, wherein establishing the connection between the first party and the local call splitter comprises the mobile communication device of the first party substituting a number of the local call splitter for a dialled number, and passing the dialled number to the local call splitter. ### Claim 8 (depends on 7) A method as claimed in claim 7, wherein the dialled number is provided to the local call splitter in encrypted form. ### Claim 9 (depends on 1) A method as claimed in claim 1, wherein announcements are added to the call part to notify one or both of the first and second parties that the call is recorded. ### Claim 10 (depends on 2) A method as claimed in claim 2, wherein the first party is a calling party initiating the voice call. ### Claim 11 (depends on 10) A method as claimed in claim 10, wherein determining one of a set of call splitters to be a local call splitter is carried out by a service node of a home mobile telecommunications network for the first party and wherein on initiating the call, a messaging service centre of the mobile telecommunications network to which the first party is attached notifies a service point of that mobile telecommunications network, which notifies the service point of the first party's home mobile telecommunications network. ### Claim 12 (depends on 2) A method as claimed in claim 2, wherein the first party is a called party receiving the voice call. ### Claim 13 (depends on 12) A method as claimed in claim 12, wherein determining one of a set of call splitters to be a local call splitter is carried out by a service node of a home mobile telecommunications network for the first party, wherein the home mobile telecommunications network notifies the local call splitter by intelligent network signalling, and wherein on initiation of the call, the messaging service centre of the first party's home mobile telecommunications network notifies the local call splitter while establishing the call to a mobile telecommunications network visited by the first party. ### Claim 14 (depends on 1) A method as claimed in claim 1, wherein the recording service continually notifies the local call splitter of successful recording. ### Claim 15 (depends on 12) A method as claimed in claim 12, wherein on failure of successful recording, the call is terminated. ### Claim 16 A media recording service adapted on either the first party or the second party initiating a call with the other party; to determine one of a set of call splitters distributed through the plurality of telecommunications networks to be a local call splitter to the first or the second party; to establishing a connection between the first party and the local call splitter to split the call into a recording part and a call part, wherein the call part is routed between the first party and the second party via the call splitter to provide transmission of media between the first party and the second party, and to provide, by the local call splitter, the recording part to a recording service associated with the first party. ### Claim 17 A service control point of a mobile telecommunications network adapted to determine a local call splitter from a plurality of call splitters for a subscriber to that mobile telecommunications network currently roaming on another network. ### Claim at position 18 18-19.
