Systems and methods for supporting fixed tracking areas and fixed cells for mobile satellite wireless access
Access, mobility management and regulatory services are supported for satellite access to a 5G core network. A coverage area, e.g., a country or region, is divided into fixed virtual cells and fixed tracking areas. The UE receives configuration information for fixed cells and fixed tracking areas associated with a serving PLMN. The fixed cells and the fixed tracking areas are defined, independently of each other, as fixed geographic areas. A position of the UE is used to determine a fixed serving cell and/or fixed tracking area for the UE. A service operation for the UE is enabled for the serving PLMN based on the fixed serving cell or the fixed tracking area. A fixed cell may be associated with an overlapping fixed tracking area by assigning a color code to the tracking area and appending the color code to an ID for the fixed cell.
Geographical Zone-based Registration Area Tracking
An access and mobility management function (AMF) receives, from a wireless device, a first registration request message comprising a first zone identity of the wireless device, wherein the first zone identity is based on a first geographical location of the wireless device, and a registration area update type indicating a geographical zone-based tracking type. The AMF sends a paging message for the wireless device based on the geographical zone-based tracking type.
Method, Device and Computer Readable Medium for Supporting Satellite Access
Method, device and computer readable medium are disclosed for supporting satellite access. The registration management entity of the network determines information regarding which beam covering the location of the terminal device and the corresponding timing; the terminal device triggers a registration update based on the information determined by the registration management entity. Thus, the method, device and computer readable medium can introduce less modification to the network and have good compatibility.
Real-time kinematics for a vehicle system
A communication system includes communication units onboard a vehicle system. A first unit receives satellite positioning data and correction data based on phase measurements of satellite signals. A second unit receives the satellite positioning data. One or more processors determine a first geographical position of the first unit based on the position correction data and the satellite positioning data. The processors communicate the position correction data or a copy thereof to the second unit. The processors determine second geographical position data of the second unit based on the position correction data and the satellite positioning data. The one or more processors communicate the second geographical position data that is determined to the first communication unit.
UNMANNED AERIAL SYSTEM COMMUNICATION DUPLICATE REGISTRATION ID DETECTION AND RECOVERY
Systems, apparatuses, and method may provide unmanned aerial system communication. A method performed by at least one processor included in an unmanned aerial system (UAS) includes: transmitting, to a UAS Service Supplier (USS) implemented on at least one server, a first registration request to register a first remote identification (RID) corresponding to the UAS with the USS; receiving, from the USS, an indication that the first RID is a duplicate RID that is registered with the USS; determining, based on the first RID, a second RID corresponding to the UAS; and transmitting, to the USS, a second registration request to register the second RID.
WIRELESS NETWORK SELECTION IN INTERNATIONAL AREAS
A method of wireless communication performs a public land mobile network (PLMN) search for a higher priority PLMN. The PLMN search includes a candidate PLMN having a different mobile country code (MCC) than a serving PLMN. The method switches to the higher priority PLMN when the PLMN search locates the higher priority PLMN. A method determines whether a user equipment (UE) has transitioned between an international area and a national area. The method triggers PLMN selection in response to the UE having transitioned between the international area and the national area.
SYSTEMS AND METHODS FOR ENABLING DATA AND VOICE COMMUNICATIONS VIA SATELLITE NETWORK
Systems and methods for enabling data and voice communications via a satellite network are disclosed herein. In an embodiment, a method of enabling data and voice communications for a user terminal includes establishing a local connection between the user terminal and a first core network operated by a first network provider, routing data communications received by the first core network from the user terminal to a satellite terminal operated by the first network provider for further transmission via a satellite, and routing voice communications received by the first core network from the user terminal to a second core network operated by a second network provider.
POSITIONING METHOD, DEVICE, ELECTRONIC EQUIPMENT AND STORAGE MEDIUM
A positioning method may include: receiving a positioning signal of at least one constellation; determining a quality parameter of each constellation of the at least one constellation correspondingly based on the positioning signal of the at least one constellation; controlling a terminal equipment to stop receiving the positioning signal of the constellation of the at least one constellation, where the quality parameter of the constellation meets a preset condition.
Methods for Tracking Area Management for Moving RAN
A method performed by a network node (160) includes serving a cell area by a first physical network node for a first time duration. The first physical network node uses an identifier of a logical network node. For a second time duration, the cell area is served by a second physical network node. The second physical network node uses the identifier of the logical network node. The first physical network node serves the cell area with a first frequency band and the second physical network node serves the cell area with a second frequency band.
DEFAULT BEAM FOR COMMUNICATION NETWORKS
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine an inactivity timer associated with a first set of one or more beams used for communicating with a network entity associated with a satellite has expired. The UE may identify location information corresponding to the location of the UE with respect to the network entity. The UE may identify beam geometry information for one or more beams associated with the network entity. For example, the UE may receive the beam geometry information from the network entity. The UE may process the location information and the beam geometry information to identify a second set of one or more beams, the second set different than the first set. The UE and the network entity may communicate according to the second set of one or more beams.
