  • Patent number: 10542452
    Abstract: Quality of service may be enhanced for high priority traffic. A UE may communicate within a packet switched system, e.g., an LTE network. The UE may use a first or default bearer for signaling messages of high priority services and a second bearer for messages of low priority services. For example, the first bearer may have a quality of service class identifier (QCI) value of 5 while the second bearer may have a QCI value other than 5, (e.g., 6-9). The first bearer may be used for signaling messages associated with voice over IP, video over IP, and/or SMS over IP, as desired. The second bearer may be used for messages (e.g., signaling messages) associated with other, lower priority services. For example, the second bearer may be used for presence messages or instant messages or other lower priority messages.

  • Patent number: 10531509
    Abstract: Apparatus and methods to support IP flow mobility (IFOM) via multiple wireless accesses in a wireless device are disclosed. The wireless device initiates network-based IFOM (NB-IFOM) to establish and manage IP flows. Support for NB-IFOM is negotiated during initial attach procedures to either or both wireless accesses and by using packet data network (PDN) connectivity procedures. The wireless device sends routing rules including priorities to apply to both existing and future IP flows or to future IP flows only. The wireless device requests to move IP flows from a source access to a target access. When a new wireless access is added to an existing PDN connection, an identical IP address for the wireless device is allocated as used for the existing PDN connection. The network establishes a GPRS tunneling protocol (GTP) tunnel for the new wireless access while maintaining a previously established GTP tunnel for the existing wireless access.

  • Publication number: 20200008167
    Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for de-registration of the wireless device from a first access type over a second access type. Methods also include procedures for maintaining state machines associated with both access types as well as procedures to determine a connection for re-transmitting a de-registration request and to avoid collisions between procedures associated with the first and second access types. Further, methods include an information element configured to indicate which access type has been de-registered.

  • Publication number: 20190357019
    Abstract: This disclosure relates to techniques for managing mobile-terminating short message service re-transmissions for wireless devices. A cellular network entity of a cellular network may receive a request to provide a short message service message to a wireless device. The wireless device may be registered with the cellular network entity via at least two access types. An attempt to provide the short message service message to the wireless device via a first access type may be performed. An attempt to provide the short message service message to the wireless device via a second access type may be performed if the attempt to provide the short message service message to the wireless device via the first access type is unsuccessful.

  • Publication number: 20190349816
    Abstract: An accessory device may dynamically determine to transition a cellular connection between mobile-initiated communication only (MICO) mode and non-MICO mode based on a variety of factors. The accessory device may be configured to communicate through a non-cellular network in addition to the cellular network. The accessory device may transition from MICO to non-MICO mode based on one or more of: loss of the non-cellular connection; location of the accessory device; a call, data, or SMS request failure over the non-cellular network; or other factors.

  • Publication number: 20190350044
    Abstract: This disclosure relates to transmitting an emergency message to a user equipment device (UE) over a wireless local area network (WLAN). The UE may establish a connection with an access point through WLAN. The UE may transmit, via the access point and to a network entity, an indication that the UE supports receiving emergency messaging through the WLAN. At least in part in response to communicating the indication, the UE may receive, from the network entity and via the access point, an emergency message and location information. The UE may compare the location information with a location of the UE to determine whether the UE is located within a first region specified by the location information. Based on a determination that the location of the UE is within the first region, the UE may display the emergency message on a display of the UE.

  • Publication number: 20190312868
    Abstract: Apparatus and methods to support authentication failure handling by network elements and by a wireless communication device when attempting access to services through non-cellular wireless networks by the wireless communication device are disclosed. Error messages received from evolved packet core (EPC) network elements, such as an authentication, authorization, and accounting (AAA) server, are mapped to failure messages provided to wireless communication devices by internetworking equipment, such as an evolved packet data gateway (ePDG). The wireless communication device determines a failures cause based on the failure messages and disallows retry attempts until select criteria are satisfied.

  • Publication number: 20190306068
    Abstract: This disclosure relates to techniques for providing a multipath transmission control protocol proxy in a cellular network. A wireless device may establish a wireless link with a cellular network. The wireless device may provide an indication that the wireless device is multipath transmission control protocol (MPTCP) capable to a core network entity of the cellular network. The wireless device may receive MPTCP proxy information for a MPTCP proxy comprised in the cellular network from the core network entity. The MPTCP proxy information may include MPTCP server IP address and port information. The wireless device may establish a first MPTCP flow with the MPTCP proxy comprised in the cellular network via the wireless link.

  • Publication number: 20190306823
    Abstract: This disclosure relates to techniques for network delaying cellular re-registration during critical conditions. A wireless device may register for cellular service with a cellular network. The wireless device may receive a configuration update command from a network element of the cellular network. The configuration update command may request re-registration of the wireless device. The wireless device may determine to delay responding to the configuration update command based at least in part on one or more conditions in effect at the wireless device. For example, one possible such condition may include if a protocol data unit session associated with emergency services is active at the wireless device.

  • Patent number: 10383016
    Abstract: Apparatus and methods to support emergency services through untrusted wireless networks by a user equipment (UE) are disclosed. The UE detects a request for emergency services to be provided via an untrusted wireless network. The UE de-registers from any non-emergency services and releases any existing PDN connections. The UE sends a request for emergency services to an evolved packet data gateway (ePDG) at an Internet Protocol (IP) address obtained from a table or from a domain name system (DNS) server. The request includes an indication for emergency services using a configuration attribute assigned to indicate emergency services. The UE receives from the ePDG an indication of support for emergency services in a reply to the request.

  • Publication number: 20190069338
    Abstract: 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.
