Description

Method, device and system for network access Technical Field The present invention relates to methods, apparatuses and systems for enhancing communication when a wireless device, such as a user equipment, performs network access with a wireless access device, such as a base station, in a wireless system, such as a cellular system, a WiFi network, etc. Background In a conventional cellular network, a primary station serves a plurality of secondary stations located within a cell served by the primary station. Wireless communication is accomplished from the primary station to each secondary station on a downlink channel. Instead, wireless communication from each secondary station to the primary station is accomplished on an uplink channel. Wireless communications may include data traffic (sometimes referred to as user data) and control information (sometimes referred to as signaling). The control information typically includes information (e.g., resource allocation/request, physical transmission parameters, information about the status of the respective stations) that assists the primary and/or secondary stations in exchanging data traffic. In the context of cellular networks standardized by 3GPP, the primary station is called a base station, or eNodeB (or eNB) in gNodeB (or gNB) or 4G (LTE) in 5G (NR). The eNB/gNB is part of a radio access network, RAN, which interfaces with functions in the Core Network (CN). In the same context, a secondary station corresponds to a mobile station or user equipment (or UE) in 4G/5G, which is a wireless client device or a specific role played by such a device. The term "node" is also used to denote a UE or a gNB/eNB. In addition, for example, in the case of a PC5 interface or side-link communication, there may be direct communication between secondary stations (here UEs). The UE may then also operate as a relay to allow, for example, an out-of-coverage UE to obtain an intermediate (or indirect) connection to the eNB or the gNB. To be able to operate as a relay, the UE may use the discovery message to establish a new connection with other UEs. Therefore, the role of relay node is introduced in 3 GPP. The relay node is a wireless communication station including a function for relaying communication between a primary station such as a gNB and a secondary station such as a UE. The relay function allows, for example, to extend the coverage of a cell to out-of-coverage (OoC) secondary stations. The relay node may be a mobile station or may be a different type of device. In the specification of 4G, proximity services (ProSe) functionality is defined in particular in TS 23.303 and TS 24.334 to enable connections for cellular User Equipments (UEs) that are temporarily not within the coverage of the cellular network base station (eNB) serving the cell, etc. This particular function is referred to as ProSe UE-to-network relay, or simply relay UE. The relay UE relays applications and network traffic in both directions between the OoC UE and the eNB. The local communication between the relay UE and the OoC UE is referred to as device-to-device (D2D) communication or side-link (also referred to as PC 5) communication in TS 23.303 and TS 24.334. Once the relay relationship is established, the OoC-UE makes an IP connection, e.g., via the relay UE, and plays the role of a "remote UE". This means that the remote UE has an indirect network connection with selected functions of the core network, rather than a direct network connection with all core network functions as is normal. Furthermore, the role of UE-to-UE relay nodes, i.e. relay nodes that relay communications between two UE devices, has been introduced. The relay node relays communications between the UE devices. The UE may connect to the core network through the base station while in coverage. In such a relay scenario, the relay device receives and stores some information for a period of time and then forwards it to the target device. This information, which may be stored and forwarded, may be a discovery message received from the source UE, where the relay UE may release them at some later point in time. This information, which may be stored and forwarded, may be a SIB, which may contain a timestamp. In addition, cellular networks are evolving to enable more mobile access devices (such as satellites, unmanned aerial vehicles, buses, or trains) to store data for a period of time before forwarding it further. Examples relate to a satellite that receives and stores certain data when it is close to a ground gateway and releases the data only when the receiver is in coverage. Such a mobile access device may operate in a transparent manner or in a regenerative manner. In the transparent mode, the mobile access device acts as a reflector/intelligent repeater that resends communications sent by, for example, a gateway (e.g., a non-terrestrial network gateway) to the UE. In the regeneration mode, the mobile access device operates as a base sta
