摘要： Apparatus and methods to support emergency services sessions by network elements and by a wireless device are disclosed. The wireless device, when roaming to a visited country/region, queries a network-based server to obtain information for Public Land Mobile Networks (PLMNs) that support emergency services sessions via non-cellular wireless access in the visited country/region. The network-based server responds with a list of PLMNs from which the wireless device selects a PLMN. The wireless device further queries the network-based server to obtain information for evolved Packet Data Gateways (ePDGs) for a selected PLMN and receives from the network-based server a list of Internet Protocol (IP) addresses for ePDGs that support emergency services sessions via non-cellular wireless access for the selected PLMN. The wireless device further queries the network-based server for local numbers of the visited country for establishing emergency services sessions and receives a categorized list of local numbers for emergency services.

摘要： Techniques to manage updates for eSIMs of a secondary wireless device are disclosed. Responsive to a user input, expiration of a timer, receipt of a message from an associated primary wireless device, processing circuitry of the secondary wireless device commands an eUICC to update an eSIM. A secure data connection is established between the eUICC and a network provisioning server, either directly from the secondary wireless device to a cellular wireless network or relayed indirectly via the primary wireless device. The eUICC and the network provisioning server exchange messages in accordance with a BIP process to update the eSIM. The eUICC provides a status to the processing circuitry indicating success or failure for the eSIM update. Upon success, a portion of the secondary wireless device may be placed in a reduced power state. Upon failure, the eSIM update process may repeat up to a maximum number of retries.

摘要： A method for negotiating a session personality based at least in part on a roaming agreement is provided. The method can include a roaming access network receiving an identifier provided by an access terminal attendant to establishment of a session between the access terminal and the roaming access network. The method can further include the roaming access network using the identifier to determine a home network associated with the access terminal. The method can additionally include the roaming access network determining one or more radio access technology (RAT) versions covered by a roaming agreement between the home network and the roaming access network. The method can also include the roaming access network negotiating a session personality for use in the session based at least in part on the one or more RAT versions covered by the roaming agreement.

摘要： This Application sets forth techniques for provisioning and activating electronic subscriber identity modules (eSIMs) for mobile wireless devices. An eSIM is reserved during a sales order process and later activated during device activation after receipt by a user. An option for eSIM installation in place of (or in addition to) physical SIM installation is provided when purchasing the mobile wireless device. The reserved eSIM can replace a previous SIM/eSIM or be a new eSIM. During device activation, installation and activation of the eSIM occurs. Activation of the eSIM can occur before or after deactivation of a transferred SIM/eSIM. The mobile wireless device accounts for propagation delay of eSIM activation through MNO servers by disabling and re-enabling the eSIM until initial attachment to an MNO cellular wireless network succeeds or a maximum number of retry attempts is reached.

摘要： This application sets forth techniques for provisioning electronic subscriber identity modules (eSIMs) to mobile wireless devices that do not include functional bootstrap provisioning profiles to obtain access to a cellular wireless network. Connectivity to a cellular wireless network can be allowed for provisioning one or more eSIMs to a mobile wireless device using hardware device identifiers for authentication and a limited purpose provisioning connection when the cellular wireless network supports provisioning connections without the use of a provisioning profile for access.

摘要： A server of a wireless operator creates a roaming list based on a user's roaming plan and sends the roaming list to the user's wireless device. The roaming list includes a list of public land mobile networks (PLMNs). When the user travels away from their home wireless network to another geographic area, the wireless device scans based on the roaming list for radio signals. The roaming list contributes to user satisfaction because timely attachment to a radio network while away from home occurs efficiently since the wireless operator creates the roaming list based on both i) roaming agreements that the wireless operator is a party to with other wireless operators, ii) the user's roaming plan, iii) the radio access technology (RAT) capabilities of the wireless device and iv) the RAT capabilities of other wireless operators in particular geographic regions.

摘要： Methods, apparatuses and computer readable media are described to compensate for radio frequency link imbalances in a wireless communication device. Processing circuitry in the wireless communication device detects a radio frequency link imbalance for a bi-directional communication link. The wireless communication device biases one or more operational parameters of the wireless communication device to adjust for a performance degradation induced by the radio frequency link imbalance. The wireless communication device determines whether a trigger condition for cell selection, reselection, or handover occurs based on the biased operational parameters, and when the trigger condition occurs, performs a remediating action to compensate for the radio frequency link imbalance. Remediation can include performing an intra-RAT or inter-RAT reselection or handover.

摘要： Apparatus and methods to support access to services of multiple wireless networks by a single-radio, multiple subscriber identity module (SIM)/electronic SIM (eSIM) wireless device are disclosed. To send or receive voice communications for multiple SIMs/eSIMs, when an active voice connection for a first SIM/eSIM uses wireless circuitry to connect to a first cellular wireless network via a first radio access network, the single-radio, multi-SIM/eSIM wireless device uses alternative data transports, such as via a wireless local area network (WLAN) or by tunneling through the first radio access network of the first cellular wireless network to connect to services of additional cellular wireless networks associated with the multiple SIMs/eSIMs.
