Dynamic resource sharing among cellular networks
First Claim
1. A method in a base station controlled by a home operator and serving mobile terminals in one or more sectors, comprising:
- receiving sharing instructions from a core network controlled by the home operator;
activating a sharing state in a selected one or more of the sectors in response to the sharing instructions;
identifying a group of sharing partners from the sharing instructions, wherein the sharing partners include the home operator and at least one further operator and are parties to a sharing agreement while said sharing agreement is in effect;
announcing identities of each of the sharing partners to the mobile terminals of the selected one or more sectors in broadcast messages; and
deactivating the sharing state when the sharing agreement expires or terminates, wherein,the sharing agreement specifies terms under which one or more parties to the sharing agreement borrow cellular resources that affect capacity and one or more parties supply cellular resources that affect capacity; and
the activation of the sharing state includes directing that during the sharing state, all mobile terminals in the selected one or more sectors that subscribe to any sharing partner of the group of sharing partners shall be treated as home subscribers;
wherein,the base station is an eNodeB of an LTE network,the activation and deactivation of the sharing state includes communicating with an MME situated in the core network controlled by the home operator,the method further includes, communicating with two or more gateways for management of user-plane mobility,one gateway of the two or more gateways is situated in the core network controlled by the home operator, andat least one gateway of the two or more gateways is situated in a core network controlled by a further operator.

Abstract
According to a disclosed method, an MME in a network analyzes KPIs from the cells it serves and based on the KPIs, it decides to engage in sharing. The MME then contacts a sharing entity (SE) to announce that it wants to borrow or to supply resources. The MME obtains terms of a sharing agreement from the SE and the MME obtains the identity of the other network. In response to this information, the MME configures its network elements to share. The MME'"'"'s own network may be a supplier or a borrower. If the network is a supplier, the MME configures its base stations to support UEs subscribing to the other network. If the network is a borrower, the MME configures its UEs to accept service from the other network'"'"'s base stations. The SE applies knowledge of network topology and of services offered. This knowledge is obtained from a sharing database. At the expiration of the sharing agreement, the SE tells the MMEs to deactivate the sharing agreement.

3. A wireless base station, comprising:
-
circuitry configured to, provide sector-specific service to mobile terminals, in each of one or more respective sectors, that subscribe to at least a first operator; activate and deactivate a sharing state in one or more selected sectors in response to instructions received by the base station from a core network controlled by the first operator; identify a group of sharing partners from the received instructions; and announce identities of the sharing partners to the mobile terminals in broadcast messages, wherein, the sharing partners are network operators, including the first operator and at least one further operator, that are parties to a sharing agreement while said sharing agreement is in effect; the sharing agreement specifies terms under which one or more parties borrow cellular resources that affect capacity and one or more parties supply cellular resources that affect capacity; the activation of a sharing state includes directing that during the sharing state, all mobile terminals in the one or more selected sectors that subscribe to any sharing partner shall be treated as home subscribers; and the sharing state is deactivated when the sharing agreement terminates or expires; wherein, the base station is an eNodeB of an LTE network; the base station is configured for connection to an MME for activation and deactivation of the sharing state, the MME being situated in a core network controlled by the first operator, the base station is configured for connection to two or more gateways for management of user-plane mobility, one gateway of the two or more gateways is situated in the core network controlled by the first operator, and at least one gateway of the two or more gateways is situated in a core network controlled by a further operator. - View Dependent Claims (4, 5)
