Abstract
A method and apparatus for providing regional subscription data in a network where a gateway location register is serving networks in more than one country. Further, regional subscription information is also provided where a gateway location register serves a plurality of networks in the same country. In addition, efficient routing of mobile terminated short message service packets and packet data is provided.
Claims29
In a network where a gateway location register serves a first visitor location register in a first country and a second visitor location register in a second country, a method for providing regional subscription data to a serving visitor location register comprising the steps of:
- responsive to receiving a location update from a mobile subscriber in a network said serving visitor location register sending a MAP_UPDATE_LOCATION request message to the gateway location register:
- determining whether this is the first location update for the mobile subscriber in a network served by the gateway location register;
- determining whether this is the first location update in a new country for the mobile subscriber;
- and
- forwarding the MAP_UPDATE_LOCATION request message to, and requesting regional subscription data from a home location register associated with the mobile subscriber if the location update is not the first location update for the mobile subscriber in the network and if the location update is the first location update for the mobile subscriber in the new country, wherein the forwarded MAP_UPDATE_LOCATION request message includes a dummy mobile switching center location address to indicate the presence of the gateway location register.
In a network where a gateway location register serves a first visitor location register in a first network and a second visitor location register in a second network, the first and second networks being located in a same country, a method for providing regional subscription data to a serving visitor location register comprising the steps of:
- responsive to receiving a location update from a mobile subscriber in a network said serving visitor location register sending a MAP_UPDATE_LOCATION request message to the gateway location register;
- determining whether this is the first location update for the mobile subscriber in the first and second networks;
- determining whether this is the first location update for the mobile subscriber in a new network served by the gateway location register;
- forwarding the MAP_UPDATE_LOCATION request message to, and requesting regional subscription data from, a home location register associated with the mobile subscriber if the location update is not the first location update for the mobile subscriber in the first and second networks and if the location update is the first location update for the mobile subscriber in the new network wherein the forwarded MAP_UPDATE_LOCATION request message includes a dummy mobile switching center address to indicate that the network includes a GLR.
In a network where a gateway location register serves a visitor location register, a method for delivering short message service messages to a mobile subscriber located in a visited network comprising the steps of:
- indicating to a home location register associated with the mobile subscriber that the gateway location register is present in the visited network;
- responsive to receiving a location update from the mobile subscriber, the visitor location register sending a MAP_UPDATE_LOCATION request message to the gateway location register;
- forwarding the MAP_UPDATE _LOCATION request message to the home location register, wherein the forward MAP_UPDATE_LOCATION request message includes a dummy mobile switching center address to indicate that the network includes a GLR;
- and
- requesting an address of a mobile switching center which is serving the mobile subscriber in the visited network from the gateway location register.
In a network where a gateway location register serves a serving support node, a method for delivering packet data to a mobile subscriber located in a visited network comprising the steps of:
- indicating to a home location register associated with the mobile subscriber that the gateway location register is present in the visited network;
- responsive to receiving a location update from the mobile subscriber, the visitor location resister sending a MAP_UPDATE_GPRS_LOCATION request message to the gateway location resister:
- forwarding the MAP_UPDATE_GPRS_LOCATION request message to the home location register, wherein the forwarded MAP_UPDATE_GPRS_LOCATION request message includes a dummy mobile switching center address to indicate that the network includes a GLR;
- and
- requesting an address of a serving support node which is serving the mobile subscriber in the visited network from the gateway location register.
