“…By caching the user's downlink data in multiple satellites simultaneously, the ground user can seamlessly switch and always access the satellite with the best link quality. The mobility management architecture based on location and identity separation and convergent switching mechanism of satellite network are proposed in [12] and [13]. According to the distribution of the ground gateway, the coverage area of the satellite constellation can be divided into several areas.…”

The geographic information-based subnet partitioning scheme provides the basis for satelliteground integrated addressing. Meanwhile, this scheme will inevitably cause addressing abnormal users (AAUs), i.e., the satellite which has address convergence relationship with users' co-subnet and the satellite which users actual access to may be different. This problem will decrease the network communication efficiency. With the aim of quantifying the statistical variation pattern of AAUs to reduce the impact, this paper constructs a statistical model of AAUs under the general closed geographic partition shape. Further, considering the orbit characteristics and the uniform rotation of Earth, this paper derives an analytic formula for the average addressing abnormal user rate (AAUR) under circle and polygon geographic partition. Meanwhile, by simulating a specific LEO satellite constellation, this paper obtains the temporal average of AAUR in spherical trapezoidal partition during one orbital period, which is sufficiently approximated to the result of analytic formula, verifying the validity of this model. The model shows that the average of the AAUR decreases gradually as the ratio of satellite coverage area to geographic partition area increases. When the ratio is greater than 1.6, the average AAUR is less than 5%. The research work in this thesis quantifies the relationship between the average of the AAUR and satellite to earth communication range, geographic subnet range, geographic subnet shape, which can provide a reference for the matching design of geographic partitioning under any constellation configuration.INDEX TERMS Addressing scheme, IP/LEO network, mobility management, subnet division.

“…Due to the differences between terrestrial networks and SatNets in terms of topology, processing power, and communication links, the application of standard IP mobility management protocols, and more specifically their location management techniques, to satellite network has some drawbacks [3]. IETF's IP-based location management techniques were designed to manage the logical location of MNs (terminals) and deliver their data to wherever they move.…”

“…A LMA is connected to multiple MAGs and in one PMIPv6 domain, there can be multiple LMAs managing the mobility of a different group of MNs. When the MN is moving within a PMIPv6 domain, the MAG performs the signaling interaction with the LMA on behalf of the MN to ensure session continuity [3]. When a MN joins the network, it will send a RS to the reachable MAG.…”

“…Unlike terrestrial networks that are geographically bounded, future SatNets will have a global scale which makes the adoption of the IETF's mobility management standards infeasible. Moreover, in all IP-based location management protocols, data packets routing go through the location management anchor thereby producing the non-optimal routing path [3]. This non-optimal data routing is unacceptable in future LEO SatNets as it will consume link resources and increase delivery delays.…”

“…Recently several industrial groups and standardization organizations, including the 3rd Generation Partnership Project (3GPP), are proposing the integration of satellite networks with 5G and beyond to support seamless and broadband coverage everywhere, for everything, at any time [2]. Driven by the growing demands for Internet and communication, satellite networks have developed fast during the last 10 years [3], especially for the low Earth orbit (LEO) satellite networks (SatNets) such as the Iridium NEXT system and the upcoming SpaceX mega-constellations. The objective is to cover the entire Earth with LEO satellites equipped with On-board Processor (OBP) devices.…”
