PROVISIONING AVAILABLE NETWORK RESOURCES

摘要

Systems and methods are provided that allow network resources to be shared across geographical distances. This can be achieved by changing the resources available for establishing and handling call or data session processing in an area. A mobility management device can alone or in combination with a DNS server change the size or the resource pool available in some embodiments. The change in resources can be dynamic according to certain predefined conditions or can be setup beforehand to account for daily demand. This sharing of resources can allow more efficient usage of resources available across a geographic region, rather than needed to over-provision each region to account for peak demands.

1. A method comprising:
maintaining, at a domain name system (DNS) server, a first list of gateway addresses corresponding to a first set of gateways that are available to handle a new session originating at a mobility management entity (MME), wherein the gateways are geographically located within a dynamically-resizable tracking area (TA); resizing, at the DNS server, the dynamically-resizable TA based on evaluating network load information for at least some of the gateways in the first set of gateways; identifying, at the DNS server, a second list of gateway addresses corresponding to a second set of gateways which are geographically located within the newly resized dynamically-resizable TA, wherein the second set of gateways is different from the first set of gateways; receiving a request at the DNS server from the MME for a gateway to handle a new session; and providing the second list of gateway addresses from the DNS server to the MME.
