Information exchange between a mobile transport network and a core network
First Claim
1. A method performed in a network controller of a Mobile Transport Network, the Mobile Transport Network comprising communication links interconnecting network entities of a cellular Radio Access Network (RAN) and a core network, the method comprising:
- receiving, from a network node in the core network, an indication of traffic load within the RAN or between the RAN and the core network, wherein receiving the indication of traffic load comprises receiving a message over a GPRS Tunnelling Protocol (GTP) based interface from the network node in the core network, and wherein the message is a GTPv2-C protocol message; and
optimising resources within the Mobile Transport Network according to the received indication of traffic load within the RAN or between the RAN and the core network.

Abstract
A method (100) is disclosed, the method being performed in a network controller of a Mobile Transport Network. The Mobile Transport Network comprises communication links interconnecting network entities of a cellular Radio Access Network (RAN) and a core network. The method comprises receiving, from a network entity in the core network, an indication of traffic load within the RAN or between the RAN and the core network (102). Also disclosed is a method (200), performed in a network entity of a core network, the core network being connected to a cellular RAN by a Mobile Transport Network. The Mobile Transport Network comprises communication links interconnecting network entities of the core network and the RAN. The method (200) comprises sending to a network controller of the Mobile Transport Network an indication of traffic load within the RAN or between the RAN and the core network (202). Also disclosed are a network controller (300, 500), a core network entity (400, 600) and a computer program product configured to carry out methods in a network controller a core network entity.

26. A network controller of a Mobile Transport Network, the Mobile Transport Network comprising communication links interconnecting network entities of a cellular Radio Access Network (RAN) and a core network, the network controller comprising:
-
one or more processors; and one or more memories comprising instructions that, when executed by the one or more processors, configure the one or more processors to; receive, from a network node in the core network, an indication of traffic load within the RAN or between the RAN and the core network, wherein to receive the indication of traffic load, the instructions configure the one or more processors to receive a message over a GPRS Tunnelling Protocol (GTP) based interface from the network node in the core network, and wherein the message is a GTPv2-C protocol message; and optimise resources within the Mobile Transport Network according to the received indication of traffic load within the RAN or between the RAN and the core network. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34)
