Abstract: Embodiments of this application provide a key generation method, applied to a scenario in which a base station is divided into a centralized unit and a distributed unit and a control plane and a user plane of the centralized unit are separated. And the control plane entity of the centralized unit obtains a root key, generates a user plane security key based on the root key, and sends the first user plane security key to the user plane entity of the first centralized unit. According to this application, key isolation between different user plane entities is implemented. Further, in an actual operation, the control plane entity or the user plane entity of the centralized unit may be flexibly selected to generate the user plane security key.

Abstract: A message protection method and an apparatus are disclosed. The method includes: When a terminal prepares to hand over from a first-standard system to a second-standard system, the terminal may not have a security context of the second-standard system after handover. Therefore, in the method of the present disclosure, the terminal performs integrity protection on a registration request message and a location update request message by using an integrity key in a security context of the first-standard system before handover. Both the registration request message and the location update request message are messages for triggering handover. Therefore, in the method, security protection is implemented on the message for triggering handover, thereby helping improve communication security.

Abstract: Apparatuses, systems, and methods for a wireless device to perform negotiation of bearer type configuration and/or related parameters.

The UE and the BS may exchange data using a negotiated configuration.

Abstract: Methods and techniques are described for supporting location services for a user equipment (UE) in a Fifth Generation wireless network using a Location Management Function (LMF) based control plane (CP) location solution. The LMF serves as the main anchor point for location support instead of an Access and Mobility Management Function (AMF). The LMF may be in either a serving Public Land Mobile Network (PLMN) for a UE or in a Home PLMN for a roaming UE. The LMF may obtain location information for a UE via an AMF from a Next Generation Radio Access Network or the UE and may interact with a Gateway Mobile Location Center to receive location requests from and return location information to an external client. The LMF solution may be more efficient and require less implementation than an AMF based CP location solution.

Abstract: Aspects for carrier-based blocking of contraband telecommunication devices are disclosed. In one such aspect, an entity (broadly referenced as a contractor) establishes a network at a correctional facility to collect raw data including telecommunications signaling and identifier data during a preconfiguration period. The data is then stored in a memory and processed by a processing system to determine devices that may be contraband. After the Department of Corrections (DOC) authorizes the activity by the contractor to control the devices, the contractor may send a list of contraband devices to the GSMA, the international carrier governing body, or an affiliate or designee thereof, to include in its database(s) this information. The carriers may prevent access by the contraband devices to remote networks by using a database from which an indicator can be provided when access is attempted.

In novel aspect, the UE configures a target protocol stack for a target gNB upon receiving a reconfiguration message from a source gNB, performs random access procedure and establishes RRC connection with the target gNB through the target protocol stack while simultaneously maintaining data transmission and reception with the source gNB, and releases the source RRC connection with the source gNB and performs data transmission and reception with the target gNB upon detecting one or more predefined release triggering event. In one embodiment, the target protocol stack includes a PHY layer, a MAC layer, and RLC layer, a PDCP and optionally a SDAP. In one embodiment, the UE enables a PDCP reordering, wherein the PDCP reordering is performed on PDCP packet data units received from the source and the target protocol stacks.

Abstract: Systems and methods are provided for setting handover thresholds and dynamically initiating handovers based on antenna parameters and wireless device location. A processor identifies an antenna having a sector power ratio exceeding a predefined threshold. Undesirable locations for wireless devices relative to the antenna are determined based on stored information and a first handover threshold is set for wireless devices served by the antenna and in undesirable locations. When a wireless device is found in the undesired location and the sector power ratio exceeds the predefined threshold, the first handover threshold is met. A handover may be initiated.

Abstract: Techniques and apparatuses described herein provide for an indication that a unified access control (UAC) parameter of a user equipment (UE) has changed. For example, a paging message or direct indication information may be provided to a UE indicating that a UAC parameter has changed. In such a case, the UE may not be expected to periodically check a scheduling information list of a system information block type 1 (SIB1). Thus, battery power of UEs may be conserved and signaling resources that would otherwise be used to periodically check the scheduling information list may be conserved.
