Methods, apparatuses, system, related computer program product and data structures for informing of roaming restrictions
View Patent ↗It is disclosed a method (and related apparatus) comprising transmitting, after a network entry authentication procedure, between an access network gateway entity and one of a terminal and a serving entity, generated terminal mobility restriction information in the form of at least one text information element comprised in an authentication notification message, and receiving the terminal mobility restriction information; and a method (and related apparatus) comprising transmitting, via network entity management procedures, terminal mobility restriction information in the form of at least one additional leaf node being added to a network entity management object, and receiving the terminal mobility restriction information.
1. A method, comprising:
at least one of transmitting and receiving, after a network entry authentication procedure, between an access network gateway entity and one of a terminal and a serving entity, generated terminal mobility restriction information in the form of at least one text information element comprised in an authentication notification message, wherein at least one of the following applies:
the at least one text information element is constituted by a type-length-value information element;
the at least one type-length-value information element comprises sub information elements relating to at least one of a restriction type, a list of allowed base stations, a list of prohibited base stations, and an allowed location of the terminal; and
the authentication notification message is constituted by a extensible authentication protocol notification request message.
2. The method according to claim 1 , wherein, if the transmitting or receiving is performed between an access network gateway entity and the serving entity, at least one of the following applies:
the serving entity is situated in one of a home connectivity service network and a local visited connectivity service network;
the authentication notification message is carried by one of a remote authentication dial-in user service request and a diameter request, both relating to an access, authorization, and accounting protocol; and
the authentication notification message is carried across an R3 interface between the access network gateway entity and the serving entity.
3. An apparatus, comprising:
at least one of a transmitter configured to transmit and a receiver configured to receive, after a network entry authentication procedure, between an access network gateway entity and one of a terminal and a serving entity, generated terminal mobility restriction information in the form of at least one text information element comprised in an authentication notification message, wherein at least one of the following applies:
the at least one text information element is constituted by a type-length-value information element;
the at least one type-length-value information element comprises sub information elements relating to at least one of a restriction type, a list of allowed base stations, a list of prohibited base stations, and an allowed location of the terminal; and
the authentication notification message is constituted by a extensible authentication protocol notification request message.
4. The apparatus according to claim 3 , further comprising a generator configured to generate the authentication notification message comprising the terminal mobility restriction information in the form of the at least one text information element.
5. The apparatus according to claim 3 , wherein, if at least one of the transmitter and the receiver is comprised in an access network gateway entity or the serving entity, at least one of the following applies:
the serving entity is situated in one of a home connectivity service network and a local visited connectivity service network;
the authentication notification message is carried by one of a remote authentication dial-in user service request and a diameter request, both relating to an access, authorization, and accounting protocol; and
the authentication notification message is carried across an R3 interface between the access network gateway entity and the serving entity.
6. A non-transitory computer readable storage medium including computer program code which when executed by at least one processor causes operations data structure, comprising:
at least one of transmitting and receiving, after a network entry authentication procedure, between an access network gateway entity and one of a terminal and a serving entity, generated terminal mobility restriction information in the form of at least one text information element comprised in an authentication notification message, the at least one text information element constituting terminal mobility restriction information, wherein at least one of the following applies:
the at least one text information element is constituted by a type-length-value information element;
the at least one type-length-value information element comprises sub information elements relating to at least one of a restriction type, a list of allowed base stations, a list of prohibited base stations, and an allowed location of the terminal; and
the authentication notification message is constituted by a extensible authentication protocol notification request message.
