METHOD AND SYSTEM FOR PROVIDING DATA ACCESS TO MOBILE NETWORK NODES OF A DATA NETWORK

摘要

System and method for providing data access to mobile network nodes of a digital data network, said system comprising: a local mobility anchor node, herewith LMA, which has an uplink interface to an upstream network, a plurality of mobility access gateways, herewith MAGs, which are fixed access points comprising a wired interface to the LMA, one or more mobile mobility access gateways, herewith mMAGs, which are mobile, in particular vehicle, access points comprising a wireless interface to a MAGs or other mMAGs, a mobile network node, herewith MNN, comprising a wireless interface to a MAG or mMAG, each of said mMAGs configured for establishing a network binding to the LMA through an access point, by connecting to said access point, the access point being a MAG or another mMAG, such that data packets arrived at the LMA and destined to the MNN are routed and forwarded to the MNN through the mMAG.

1. A system for providing data access to mobile network nodes of a digital data network, the system comprising:
a local mobility anchor node (“LMA”), having an uplink interface for connecting the digital data network to an upstream network; a plurality of mobility access gateways (“MAGs”) configured as fixed infrastructure access points, each comprising a wired interface for communicating with the LMA; one or more mobile mobility access gateways (“mMAGs”) configured as mobile access points, each comprising a wireless interface for communicating with the MAGs or other mMAGs; and a mobile network node (“MNN”) comprising a wireless interface for communicating with the MAGs or mMAGs; wherein each of the mMAGs is configured to establish a network binding to the LMA by connecting to an access point that is configured as a MAG or another mMAG, such that data packets received by the LMA are routed and forwarded to the MNN through the access point and the mMAG; wherein the LMA is configured to route and forward the received data packet to the MNN by:
identifying, by the LMA, the MNN in Binding Cache Entry (“BCE”) data records of the LMA and locating a respective access point in the data records;
where the respective access point is indicated as a non-mobile access point, determining that the respective access point is a fixed access point of the MNN and encapsulating or marking the packet by the LMA for transport to the fixed access point;where the respective access point is indicated as a mobile access point, encapsulating or marking the packet by the LMA for transport to the mobile access point and identifying, by the LMA as a function of the BCE data records, a subsequent respective access point;
where the subsequent access point is a non-mobile access point, determining that the subsequent access point is the fixed access point of the MNN and re-encapsulating or re-marking the packet by the LMA for transport to the fixed access point; andwhere the subsequent access point is a mobile access point, re-encapsulating or re-marking by the LMA the packet for transport to the respective mobile access point and repeatedly identifying a further subsequent mobile access point as a function of the BCE data records to locate the fixed access point and, after the fixed access point is located, re-encapsulating or re-marking the packet by the LMA for transport to the fixed access point.
