Enhanced support for roaming connectivity by user equipment associated with mobile virtual network operators
A system and method are described that are carried out by a core network element of a primary network operator (NO) to manage agreement-based limited usage of roaming mobile wireless data services of a secondary mobile network operator (MNO) by roaming user equipment (UE) devices of a mobile virtual network operator (MVNO) in accordance with usage limiting terms arising from an agreement between the primary NO and the MVNO. The method includes maintaining a roaming usage filter definition arising from the agreement between the primary NO and the MVNO. The core network element receives a connection request message from the secondary MNO for a roaming UE device for which the agreement is applicable. The core network element applies usage limiting terms of the roaming usage filter definition to the connection request, and forwards the connection request to the MVNO in accordance with a result of the applying that indicates usage limiting terms are not exceeded by a current measure of roaming mobile wireless data services by UE devices of the MVNO.
1 . A method carried out by a core network element of a primary network operator (NO) to manage agreement-based limited usage of roaming mobile wireless data services of a secondary mobile network operator (MNO) by roaming user equipment (UE) devices of a mobile virtual network operator (MVNO) in accordance with usage limiting terms arising from an agreement between the primary NO and the MVNO, the method carried out by the core network element of the primary mobile network operator comprising:
maintaining a roaming usage filter definition arising from the agreement between the primary NO and the MVNO;
receiving a connection request message from the secondary MNO for a roaming UE device for which the agreement is applicable;
applying usage limiting terms of the roaming usage filter definition to the connection request; and
forwarding the connection request to the MVNO in accordance with a result of the applying that indicates usage limiting terms are not exceeded by a current measure of roaming mobile wireless data services by UE devices of the MVNO.
2 . The method of claim 1 , wherein the roaming usage filter definition specifies a maximum concurrent roaming devices of the MVNO on the secondary MNO.
3 . The method of claim 1 , wherein the roaming usage filter definition specifies a maximum simultaneously connected roaming devices of the MVNO on the secondary MNO.
4 . The method of claim 1 , wherein the roaming usage filter definition specifies a maximum aggregated messaging transactions rate by roaming devices of the MVNO on the secondary MNO.
5 . The method of claim 1 , wherein the UE device is an Internet of Things (IoT).
6 . The method of claim 1 , wherein the core network element is at least in part a diameter routing algorithm (DRA) component augmented with additional logic for performing the applying usage limiting terms of the roaming usage filter definition to the connection request.
7 . The method of claim 1 , wherein the primary NO is a mobile network operator (MNO).
8 . A core network element of a primary network operator (NO) configured to carry out a method for managing agreement-based limited usage of roaming mobile wireless data services of a secondary mobile network operator (MNO) by roaming user equipment (UE) devices of a mobile virtual network operator (MVNO) in accordance with usage limiting terms arising from an agreement between the primary NO and the MVNO, wherein the core network element comprises:
a processor; and
a non-transitory computer readable medium including computer-executable instructions that, when executed by the processor, cause the core network element to carry out a method comprising:
maintaining a roaming usage filter definition arising from the agreement between the primary NO and the MVNO;
receiving a connection request message from the secondary MNO for a roaming UE device for which the agreement is applicable;
applying usage limiting terms of the roaming usage filter definition to the connection request; and
forwarding the connection request to the MVNO in accordance with a result of the applying that indicates usage limiting terms are not exceeded by a current measure of roaming mobile wireless data services by UE devices of the MVNO.
9 . The core network element of claim 8 , wherein the roaming usage filter definition specifies a maximum concurrent roaming devices of the MVNO on the secondary MNO.
10 . The core network element of claim 8 , wherein the roaming usage filter definition specifies a maximum simultaneously connected roaming devices of the MVNO on the secondary MNO.
11 . The core network element of claim 8 , wherein the roaming usage filter definition specifies a maximum aggregated messaging transactions rate by roaming devices of the MVNO on the secondary MNO.
12 . The core network element of claim 8 , wherein the UE device is an Internet of Things (IoT).
13 . The core network element of claim 8 , wherein the core network element is at least in part a diameter routing algorithm (DRA) component augmented with additional logic for performing the applying usage limiting terms of the roaming usage filter definition to the connection request.
14 . The core network element of claim 8 , wherein the primary NO is a mobile network operator (MNO).
