  • Publication number: 20230053014
    Abstract: Techniques are described to support call routing and location for a user equipment (UE) with satellite wireless access to a serving PLMN. The UE sends a Session Initiation Protocol (SIP) INVITE message to a network node, such as a P-CSCF, that includes an indication of satellite access for the UE. In response the network node sends a request to another network node for a cell ID for a fixed cell in which the UE is located. The fixed cell can be independent of satellite radio cells for the serving PLMN. The network node may receive the cell ID for the fixed cell and sends the SIP INVITE message to another network node (e.g., an E-CSCF or LRF) with the cell ID for the fixed cell. The other network node may use the cell ID to route the SIP INVITE message or obtain an approximate location of the UE.

  • Publication number: 20230052177
    Abstract: Techniques are described for supporting satellite wireless access for a user equipment (UE) using fixed tracking areas (TAs). TA identities (TAIs) are broadcast in a satellite radio cell by a base station indicating which TAs are covered by the radio cell. A UE can access a radio cell if at least one broadcast TAI is not forbidden for the UE. A base station provides the TAIs broadcast in a radio cell and a TAI for a TA in which a UE is located to a core network node to support access by the UE. The core network node uses the broadcast TAIs to decide whether UE access is allowed and uses the broadcast TAIs and the TAI to assign a UE registration area. The UE may transfer all the broadcast TAIs to a forbidden TAI list if UE access is rejected by the core network node.

  • Patent number: 11546950
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may truncate or remove a number of bits from its UE identity based on identity truncating information to generate a truncated UE identity. The truncated UE identity can be transmitted by eMTC devices to a base station in an RRC connection request, and can be used by the base station to determine which core network entity stores the UE's capabilities. In some implementations, the UE may truncate or remove a number of bits from the 48-bit 5G-S-TMSI based on the identity truncating information to generate a 40-bit truncated 5G-S-TMSI that can be transmitted by an eMTC device to the base station in the RRC connection request and yet still provide the base station with enough information to determine which AMF stores the UE context.

  • Publication number: 20220360947
    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a first base station and a second base station may be neighbor base stations and the first base station may receive, from the second base station, information relating to a multicast-broadcast services (MBS) session context of an MBS session supported by the second base station. The first base station may use the received MBS session context information to control communication or connections between the first base station and one or more user equipment (UEs) that are served by the first base station. For example, the first base station may use the received MBS session context information for target cell selection in a handover procedure, an MBS-specific measurement configuration, interference avoidance, or system information block (SIB) construction, among various other use cases.

  • Patent number: 11477708
    Abstract: Methods, systems, and devices for wireless communications are described that provide for a user equipment (UE) to report packet switched voice call capabilities to a base station. The UE may explicitly report voice call capabilities via one or more system-level parameters that are transmitted to the base station. The base station may operate in a first radio access network (RAN), such as a 5G or new radio (NR) RAN. In cases where the UE indicates a capability for packet switched voice calls via the first RAN, one or more voice calls may be established with the UE via the first RAN. In cases where the UE indicates that it is not capable of packet switched voice calls via the first RAN, the UE may fall back to a different RAN (e.g., a 4G or LTE RAN, a 3G RAN, or a 2G RAN) for voice calls.
