摘要： Systems and methods relating to establishment of a Packet Data Unit, PDU, session over a Non 3GPP Access to a 3GPP network and transmitting IP data and non-IP data are provided. A method of operation of a wireless device is provided and comprises sending to an AMF over an N3IWF a PDU session request to establish a PDU session to transport one of IP data or non-IP data over an established first IPsec, Security Association, SA, establishing an IPSec Child SA, for the PDU session and associating the IPSec Child SA to a PDU session then encapsulating the data using ESP encapsulation or GRE encapsulation associated with the IPSec Child SA and indicating the type of data that is being transmitted (e.g., non-IP data that comprises raw application data). In this manner, an loT device is able to securely transmit to the 3GPP network IP data/non-IP data/raw application data over an unsecure non 3GPP access network such as Wireless Local Area Network. Methods and apparatus describing the NAS signalling and the PDU session as each using their respective IPSec SA are provided. Similarly, methods and apparatus describing the NAS signalling and the PDU sessions sharing a common IPSec SA are provided. GRE encapsulation of the data within the ESP frame is described for both NAS signalling and PDU session in the case of multiple IPSec/Child SAs or common IPSec SA. Similarly, methods and apparatus are provided for the N3IWF which provides for the UE secure access to the network.

摘要： Example embodiments presented herein are directed towards a stateless mobility management node (110, 111, 115), and corresponding methods therein, for handling a mobility procedure for a wireless device (101) within a wireless communications network (100). The example embodiments provide for the management of a common external database (124) shared by the stateless mobility management node (110, 111, 115) and at least one other stateless mobility management node, and storing context information for wireless devices served by the stateless mobility management nodes. Such management allows for migrating the network towards a virtualized and stateless architecture. Thus, stateless mobility management nodes with an external database may interoperate with legacy stateful mobility management nodes.

摘要： A method is provided for facilitating recovery from the failure of a P-CSCF (13) within an IP multimedia Subsystem network. A gateway (11), such as a GGSN, monitors signals arriving at the gateway from the P-CSCF and provides an indication if the monitored signals become unacceptable, for example because of an interruption in the signals. The gateway (11) responds by signalling the unavailability of the P-CSCF (13) to user equipment (10), which was associated with the P-CSCF during a previous registration with the IMS network. In response, for example, the user equipment affected by the failure may request re-registration with the IMS network using a different available P-CSCF.

摘要： The present invention relates to a method for the redirection of a Multimedia Broadcast/Multicast Service (MBMS) session in a communication system comprising a plurality of node layers, wherein the MBMS session is redirected from one node to another node in the same node layer, such that the MBMS session is not aborted. The advantage of the invention is that an MBMS session can be redirected form one node to another node without aborting the MBMS session and thus there is no need to initialise a new MBMS session when a node in a communication system fails.
摘要翻译：本发明涉及一种用于在包括多个节点层的通信系统中重定向多媒体广播/多播服务（MBMS）会话的方法，其中MBMS会话被重定向到同一节点层中的另一个节点，使得MBMS会话不中止。本发明的优点是可以将MBMS会话从一个节点重定向到另一节点，而不会中止MBMS会话，因此当通信系统中的节点发生故障时，不需要初始化新的MBMS会话。

摘要： Packet data gateway (PDG) in an integrated WLAN - GSM/3G core network, is dis-closed comprising a router (R) having a number of gateways (Wi; OP INT 1, OP INT 2, INT DEFAULT) which are associated with various QoS traffic properties (BE, EF), an interface to a WLAN network (Wu) and an interface (Go) to a policy deci-sion function (PDF), a translating unit (TLT). The packet data gateway engages in a ser-vice based local procedure (SBLP) whereby a negotiated QoS property is received for a given session identifier as negotiated between a user entity (UE), an Application Func-tion (AF) and a Policy Decision Function (PDF). A WLAN user entity engaging with the PDG is defined. Moreover, a service based local policy procedure (SBLP) for a packet data gateway (PDG) and Service based local policy procedure for a dedicated gateway support node (GGSN) and a tunnel terminal gateway (TTG) is disclosed.

摘要： A method for multihop packet transmissions in a wireless network involves establishing a multihop route through the wireless network. After establishment of the multihop route, transmission protocol parameters are altered to minimize delays for transmissions over the multihop route and at least one packet is transmitted over the multihop route according to the altered transmission protocol parameters. In a first embodiment, the altering of the transmission protocol parameters includes setting a NAV value at each node of the multihop route for a duration of the packet transmissions over the route. In an alternative embodiment, multihop packets are assigned a higher QoS value.
