Abstract
An arrangement and method in a Public Land Mobile Network (PLMN) for selecting a gateway to connect a User Equipment (UE) to a home PLMN when the UE is located in an access network connected to a visited PLMN. The arrangement receives a first Fully Qualified Domain Name (FQDN), which includes an identity of the UE user. Based on the identity of the user and knowledge of the visited PLMN, the arrangement selects whether the UE should establish a connection only to a gateway in the home PLMN, only to a gateway in the visited PLMN, or both. The arrangement transmits to the UE, an appropriate address for the home PLMN gateway, the visited PLMN gateway, or both depending on the selection.
Claims18
An apparatus in a home Public Land Mobile Network (PLMN) of a user of a User Equipment (UE) for selecting a gateway for connecting the UE to the home PLMN when the UE is located in an access network connected to a visited PLMN, wherein the home PLMN is different from the visited PLMN and the access network, and wherein the apparatus is configured to:
- receive a first Fully Qualified Domain Name (FQDN) from the UE via the access network, wherein the first FQDN contains an identity of the user of the UE;
- determine, based on the received identity of the user and knowledge of the visited PLMN, whether the UE should establish a connection only to a gateway in the home PLMN, only to a gateway in the visited PLMN, or to both a gateway in the home PLMN and a gateway in the visited PLMN;
- and
- transmit to the UE, an address belonging to a gateway in the visited PLMN if it is determined that the UE should establish a connection only to a gateway in the visited PLMN, or an address belonging to a gateway in the home PLMN if it is determined that the UE should establish a connection only to a gateway in the home PLMN, or addresses belonging to both a gateway in the home PLAN and a gateway in the visited PLMN if it is determined that the UE should establish a connection to both.
An apparatus in a home Public Land Mobile Network (PLMN) of a user of a User Equipment (UE) for selecting a gateway through which to connect the UE to the home PLMN when the UE is located in an access network connected to a visited MAN, wherein the home PLMN is different from the visited PLMN and the access network, and wherein the apparatus is configured to:
- receive a first Fully Qualified Domain Name (FQDN) wherein the first FQDN contains an identity of the user of the UE;
- determine, based on the received identity of the user and knowledge of the visited PLMN, that the UE should establish a connection only to a gateway in the visited PLMN;
- and
- transmit, by a home PLMN Domain Name System (DNS) server, a Canonical Name (CNAME) resource record comprising a second FQDN to be used instead of the first received FQDN and to be sent to a visited PLMN DNS server, wherein the second FQDN is constructed utilizing a WLAN-Access Point Name (W-APN) network identifier and the identity of the visited PLMN, such that the visited PLMN DNS server can send a gateway address to the UE by resolving the second FQDN.
A method in a home Public Land Mobile Network (PLMN) of a user of a User Equipment (UE) for selecting a gateway for connecting the UE to the home PLMN when the UE is located in an access network connected to a visited PLMN, wherein the home PLMN is different from the visited PLMN and the access network, the method comprising the steps of:
- receiving a first Fully Qualified Domain Name (FQDN) from the UE via the access network, wherein the first FQDN contains an identity of the user of the UE;
- determining, based on the received identity of the user and knowledge of the visited PLMN, whether the UE should establish a connection only to a gateway in the home PLMN, only to a gateway in the visited PLMN, or to both a gateway in the home PLMN and a gateway in the visited PLMN;
- and
- transmitting to the UE, an address belonging to a gateway in the visited PLMN if it is determined that the UE should establish a connection only to a gateway in the visited PLMN, or an address belonging to a gateway in the home PLMN if it is determined that the UE should establish a connection only to a gateway in the home PLMN, or addresses belonging to both a gateway in the home PLMN and a gateway in the visited PLMN it is determined that the UE should establish a connection to both.
The method according to clam 14, wherein the determining step includes consulting an authentication device or a policy server in the home PLMN to determine whether connection to a gateway in the visited PLMN, connection to a gateway in the home PLMN, or connection to both should be selected.
