Abstract: Method and apparatus relating to a wireless device supporting 3GPP 4G and 5G radio interfaces and also supporting non-3GPP access, i.e., WiFi, for selecting a security gateway of a first type e.g., ePDG or a security gateway of a second type, e.g., N3IWF for accessing to the core network of first type, e.g., EPC or of a second type e.g., 5GC. As the access methods via ePDG and N3IWF are not the same, the wireless device has to determine based on information obtained by a function in the network and its capabilities whether to use an ePDG or an N3IWF for untrusted non-3GPP access. The wireless device may take into account in the selection whether it is connected to the Core network over 3GPP 4G or 5G radio access network. A corresponding apparatus claim is provided.

Abstract: A decompressor, a compressor and methods in an Internet Protocol (IP) network for reporting cause of missing packets. A cause of unsuccessful reception or sending of a compressed packet addressed is reported to a compressor/decompressor node. The compressor/decompressor node decides or predicts if a decompression context associated with the decompressor is invalidated by analyzing the cause of the unsuccessful reception and, optionally, analyzing a re-initialization agreement between the compressor and the decompressor. In an optional embodiment of the present invention, the compressor/decompressor node use the decision or prediction to exchange information to reinitialize the decompression context associated with the decompressor. In a preferable embodiment of the present invention, the detection of the unsuccessful sending or reception is performed at a Medium Access (MAC) layer associated with the compressor/decompressor node.

Abstract: An Internet Protocol (IP) headers decompressor node, a method and an IP headers manager in an IP network for fast IP headers compression initialization is thereby provided. The invention teaches how to exchange IP packets between at least two nodes of the IP network for establishment of a session therebetween, to initialize, at a first one of the at least two nodes, a static portion of a decompression context prior to completion of the establishment of the session and to uncompress application related IP packets exchanged with a second of the at least two nodes. In an optional embodiment of the present invention, it is further taught how exchanging IP packets between at least two nodes of the IP network may further comprise extracting information from the IP packets at a first one of the at least two nodes of the IP network.

This allows for an orderly queuing process and allows congestion related issues to be overcome without preempting existing network traffic.

Abstract: A system and method for optimizing the use of packet-resources by releasing a hanging packet-data connection when a Mobile Station (MS) performs a power-down while involved in a dormant packet-data session. A Base Station Controller (BSC) sends a message to a Mobile Switching Center (MSC) indicating that the MS has powered down. The MSC determines that the packet-data session is dormant, and sends an instruction to the BSC in a class-0 connectionless transaction to release network resources associated with the packet-data session. The BSC then sends an instruction to a Packet Control Function (PCF) to tear down the associated resources, and the packet-data connection is released by a Packet Data Service Node (PDSN) in response to the tearing down of the resources by the PCF.

Abstract: The invention relates a method for providing a level of service for a Mobile Terminal (MT) in a packet data telecommunications network. The further method receives at the MT from a proxy server a request message for requesting the quality of service for a session between the MT and the proxy server. The method generates, based on a proxy server IP address received during a registration of the MT at the proxy server, a token for correlating accounting information and inform the proxy server of the quality of service to be applied to packet data sent on to be sent during the session, wherein the token includes the proxy server IP address and a session identity parameter and responsive to the reception of the request from the IMS proxy server, sending a response message including the token to the proxy server.

Abstract: A method and Policy Decision Function node are provided for maintaining a multimedia session in an alive state for a mobile station following a release of a network attachment resulting from a handoff from a first Packet Data Node to a second Packet Data Node followed by a dormancy state of the mobile station. If both Packet Data Nodes are comprised into a same MultiMedia Domain, the Policy Decision Function informs an Application Function of the MultiMedia Domain that the multimedia session shall be maintained. Otherwise, if the two Packet Data Nodes are comprised into distinct MultiMedia Domains, a first Policy Decision Function, in addition to informing a first Application Function that the multimedia session shall be maintained, also fetches a context of the multimedia session. Further, the first Policy Decision Function transfers the context of the multimedia session to the first Packet Data Node, which in turn sends the context of the multimedia session to the second Packet Data Node.

Abstract: An authentication server (e.g., AAA server) is described herein which is located in a CDMA2000 network and used to authenticate a user terminal that is connected to a non-CDMA2000 network. The authentication server receives an access request for authenticating the user terminal connected to the non-CDMA2000 network. Then, it obtains a root secret key shared between the user terminal and the CDMA2000 network and generates a GSM or UMTS-like authentication vector which is used to authenticate the user terminal according to a GSM or UMTS-like authentication method. The access of the terminal to the non-CDMA2000 network is granted upon successful authentication. According to embodiments of the invention, the non-CDMA2000 network can be a WLAN network, and the authentication methods used can be EAP SIP or EAP AKA. The present invention allows one to use authentication servers that were originally intended for WLAN-3GPP interworking scenarios also in WLAN-CDMA2000 network interworking.

Abstract: A method and a packet data network for providing broadcast/multicast services (BCMCS) to a mobile terminal (MT). The method receives at a Dynamic Host Configuration Protocol (DHCP) server from the MT, for requesting an IP address of a primary BCMCS controller that serves the packet data network. The method retrieves the IP address of the primary BCMCS controller and responds to the MT with a response message from the DHCP server to the MT, the response message includes the IP address of the primary BCMCS controller. Next, the MT uses the IP address of the primary BCMCS controller and sends a Hyper Text Transfer Protocol (HTTP) request message from the MT to the primary BCMCS controller for requesting BCMCS services, the HTTP request message including a location information and an access type indicator of the MT. Afterwards, a list of available BCMCS programs is provided to the MT.
