Abstract
A mobile device for roaming between wireless communications networks in different geographical regions is provided. The mobile device includes an interface configured to transmit and receive signals over a wireless channel according to a communication mode using one of a plurality of access technologies. The device also includes a store holding a preferred roaming list having a common block holding data common to the plurality of access technologies, and a set of access technology-specific blocks each holding channel acquisition data specific to one of the plurality of access technologies for setting up the communication mode.
Claims29
An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, direct the apparatus at least to:
- cause signals to be transmitted and received over a wireless channel according to a communication mode using one of a plurality of access technologies;
- cause storage of a preferred list having a common block holding data common to said plurality of access technologies, and a set of access technology-specific blocks, each set of access technology-specific blocks configured to hold channel acquisition data specific to only one of the plurality of access technologies,
- wherein the apparatus is configured to move between wireless communications networks in different geographical regions.
A method comprising:
- managing a preferred list of a mobile device configured to cause signals to be transmitted and received using each of a plurality of access technologies;
- causing a notification message to be transmitted from a mobile device to a management server, said notification message including parameters identifying the mobile device and an access technology of a current communication mode;
- receiving an update message from the management server at the mobile device according to said communication mode;
- and
- updating, in response to at least the update message, only one access technology-specific block of a preferred list stored at the mobile device, the access technology-specific block being one of a set of access technology-specific blocks, each holding channel acquisition data specific to one of the plurality of access technologies.
A computer program product comprising a computer program code which, when executed by a processor, directs an apparatus to:
- cause a notification message to be transmitted from a mobile device to a management server in a network, said notification message including parameters identifying the mobile device and an access technology of a current communication mode;
- receiving an update message from the management server;
- and
- performing an update to only one access technology-specific block of a preferred list, the access technology-specific block being one of a set of access technology-specific blocks each holding channel acquisition data specific to one of a plurality of access technologies.
A system comprising a management server, the management server comprising:
- means for receiving a notification message from a mobile device, said notification message including parameters identifying the mobile device and an access technology of a current communication mode;
- and
- means for causing an update message to be transmitted for performing an update to only one access technology-specific block of a preferred list stored at the mobile device, the access technology-specific block being one of a set of access technology-specific blocks each holding channel acquisition data specific to one of a plurality of access technologies.
An apparatus comprising:
- means for causing signals to be transmitted and received using each of a plurality of access technologies;
- means for causing a notification message to be transmitted to a management server, said notification message including parameters identifying the device and an access technology of a current communication mode;
- means for receiving an update message from the management server according to said communication mode;
- and
- means for updating only one access technology-specific block of a preferred list, the access technology-specific block being one of a set of access technology-specific blocks, each holding channel acquisition data specific to one of the plurality of access technologies.
An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, direct the apparatus:
- manage a preferred list of a mobile device configured to cause signals to be transmitted and received using each of a plurality of access technologies;
- cause a notification message to be transmitted from a mobile device to a management server, said notification message including parameters identifying the mobile device and an access technology of a current communication mode;
- receive an update message from the management server at the mobile device according to said communication mode;
- and
- update, in response to at least the update message, only one access technology-specific block of a preferred list stored at the mobile device, the access technology-specific block being one of a set of access technology-specific blocks, each holding channel acquisition data specific to one of the plurality of access technologies.
A method comprising:
- receiving a notification message from a mobile device, said notification message including parameters identifying the mobile device and an access technology of a current communication mode;
- and
- causing an update message to be transmitted for performing an update to only one access technology-specific block of a preferred list stored at the mobile device, the access technology-specific block being one of a set of access technology-specific blocks each holding channel acquisition data specific to one of a plurality of access technologies.
