A wireless User Equipment (UE) and an Access and Mobility Management Function (AMF) establish first and second active registrations and corresponding N1s. The UE and AMF deactivate the second active registration and establish a third active registration and corresponding N1. The UE and AMF exchange active N1 signaling for the first active registration and the third active registration. The UE and AMF exchange inactive N1 signaling for the second inactive registration.

A session management function (SMF) sends, to an access and mobility management function (AMF), one or more first messages indicating user plane connection activations for a plurality of packet data unit (PDU) sessions to deliver downlink user data to one or more wireless devices. The SMF receives, from the AMF, a first time duration based on the user plane connection activations for the plurality of PDU sessions. The first time duration indicates a delay between receiving a downlink data packet and notifying the AMF about user plane connection activation for the downlink data packet. The SMF sends, to a user plane function, a second message to delay sending of further user plane connection activations to the SMF. The second message indicates a value of the first time duration.

Various embodiments are generally directed to improved channel quality information feedback techniques. In one embodiment, for example, an evolved node B (eNB) may comprise a processor circuit, a communication component for execution by the processor circuit to receive a channel quality index for a physical downlink shared channel (PDSCH), the channel quality index associated with a defined reference resource, and a selection component for execution by the processor circuit to select a modulation and coding scheme (MCS) for transmission over the PDSCH of user equipment (UE) data in one or more resource blocks, the selection component to compensate for a difference between a cell-specific reference signal (CRS) overhead of the defined reference resource and a CRS overhead of the one or more resource blocks when selecting the MCS. Other embodiments are described and claimed.

In selected embodiments, on-premises equipment of a cellular network provides local breakout functionality so that user plane data packets (PDNs/PDUs) are routed between the home/enterprise network and the Internet directly, bypassing a cloud-based core of the cellular network. The UE's control traffic is still routed to/from the core. The core may be an Evolved Packet Core (EPC) in a 4G LTE network, or a 5G Core (5GC) in a 5G network. The UE's IP addresses may be assigned by the core, or locally, by the on-premises equipment. Providing the IP context from the on-premises network allows the UE to connect to local devices, e.g., printers, disc raids, gaming and streaming nodes, and other local devices. The local IP context also pushes the complexity of the EPC core deployment to the cloud while reducing the overhead of cloud processing that comes with user plane data processing.

The present invention provides a communication means that enables use of a function for providing connectivity to a local area data network (LADN) in a 5G system (5GS). Furthermore, the present invention provides a communication means that enables use of a function for providing connectivity to an LADN between a user equipment and a network when the use of the function for providing connectivity to an LADN is enabled.

A method of authenticating a mobile station on an alternate communications network is disclosed, the mobile station being associated with a default communications network. The mobile station comprises a baseband processor to manage the antenna-related functions and a SIM card to accommodate a default SIM associated with the default communications network for receiving network credentials from the baseband processor. The method comprises providing a SIM card device to intercept communications between the baseband processor and the SIM card, monitoring the network credentials in respect of the network that the mobile station is actively in communication with, determining whether the mobile station needs to switch to an alternate network, and identifying or receiving from a user the alternate network, consulting a SIM bank, comprising at least one alternate SIM, and selecting an alternate SIM having a mobile station identification variable compatible with the alternate network, receiving a network authentication request on the mobile station from the alternate network, and allocating the selected mobile station identification variable to the mobile station so as to identify the user of the mobile station on the alternate network.

A network access method includes transmitting a request for acquiring shared network information to a shared server if a mobile communication terminal detects that a network identification of a PLMN of a visited place does not exist in a local memory of the mobile communication terminal; receiving the shared network information which the shared server transmits in response to the request, and acquiring the network identification of the PLMN of the visited place from the shared network information; adding the network identification of the PLMN of the visited place to an EPLMN list by the mobile communication terminal; and accessing a network according to the EPLMN list.

A method and apparatus for transmitting a local home network identity (LHN ID) in a wireless communication system is provided. A first evolved NodeB (eNB) transmits an X2 Setup Request message including a LHN ID of the first eNB to a second eNB, and receives an X2 Setup Response message including a LHN ID of the second eNB from the second eNB. The first eNB may determine whether or not to trigger a secondary eNB (SeNB) addition procedure according to the LHN ID of the second eNB. When it is determined that the LHN ID of the second eNB is the same as the LHN ID of the first eNB, the first eNB may trigger the SeNB addition procedure.

Some demonstrative embodiments include devices, systems and/or methods to establish a connection to the Internet via a local gateway (L-GW) function for a LIPA or a SIPTO@LN. The establishment of the connection to the Internet may be performed, for example, by at least one of an E-RAB SETUP procedure, an INITIAL CONTEXT SETUP procedure, an INITIAL UE MESSAGE procedure or an UPLINK NAS TRANSPORT procedure.

A technique for implementing an untethered access point (UAP) mesh involves enabling AP-local switching at one or more UAPs of the mesh. A system constructed according to the technique may include an untethered access point (UAP), including: a radio; a backhaul service set identifier (SSID) stored in a computer-readable medium; an anchor access point (AAP) selection engine embodied in a computer-readable medium. In operation, the AAP selection engine may use the radio to attempt to associate with the AAP if a beaconed backhaul SSID matches the stored backhaul SSID. A method according to the technique may include beaconing with a backhaul SSID, acting in concert with an upstream switch as an authenticator for a downstream station that responds to the beacon; providing limited local switching functionality for the downstream station.
