    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: 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.
