摘要:
The invention proposes a method for handling services requiring location information of a user terminal, wherein the user terminal is connected to a local network, a connection to an external network is provided via a network access means, and the network access means is identified by an identity, the method comprising the steps of extracting location information of the network access means based on the identity of the network access means, and determining the location of the user terminal based on the location information of the network access means. The invention also suggests a corresponding network control element.

Apparatus, and an associated method, for requesting, and allocating communication resources at a new fixed-site transceiver of a radio communication system, such as a new access point of a wireless local area network. A resource information container is formed that is structured to include information elements that identify, amongst other things, resource requirements of a mobile unit. The information elements of a resource information container include a root node, one or more leaf nodes, and, selectably, one or more group nodes. The resource information container is communicated prior to commencement of transition procedures to early-reserve or determine availability of resources at a new access point.

A network implementing at least one firewall for providing protection for users on the network. The network includes at least one host system protected by the at least one firewall, the host system being configured to send and receive information from external host systems through the at least one firewall. The at least one firewall including installation means for installing policy rules that are transmitted from at least one network entity to the at least one firewall. The policy rules include an option field for allowing the at least one network entity to send additional information to the firewall on at least one state to be created. The additional information is optionally used by the at least one firewall to perform services on data travelling through the at least one firewall.

Apparatus, and an associated method, for providing a mobile node with identifying indicia used to create a care/of address identifying the location of the mobile node. A router advertisement is generated by an access router. The router advertisement includes identifying indicia identifying the identity of the sub-network at which the access router is located. A detector detects the identifying indicia. A broadcast selector selectably broadcasts the identifying indicia to the mobile node. The mobile node utilizes the identifying indicia to form the care/of address.

Methods and correspondent nodes to filter IP communications through firewalls in scenarios where dynamic pinholes are created to ensure an appropriate level of security is disclosed. The invention is based on creating a secure and authorized anchor for communications where all the communications are routed through before a firewall performs the packet filtering. A Translator Gateway (TrGW) switches addresses in the header according to a stored Mapping Table and an interface between a CPS (or a SIP proxy) and the TrGW. This interface allows the CPS to request the TrGW to provide bindings data between IP addresses upon session initiation, the TrGW to provide the bindings data to the CPS and the CPS to release the bindings at session release. The firewall accepts incoming packets whose IP address belongs to the pool of addresses of the TrGW. Thus any incoming packet that does not correspond to an existing call will be dropped at the TrGW, and a valid packet will go through the firewall which will verify that the packet is not a malformed message or other attack.
摘要:
Apparatus, and an associated method, for a mobile communication system in which handovers of communications are effectuated between access points of the communication system as a mobile node travels there through. A manner is provided by which to perform handover evaluation functions more efficiently by performing at least some of the handover evaluations at the access point to which a mobile node is attached. And, a manner is provided by which to provide care-of-addresses formed of temporary identifiers to temporarily identify a mobile node to permit the routing of packet data thereto during a communication session.

The invention is a system and method of controlling an application level of access of a subscriber to a network. The method includes sending an identification of the subscriber and an application level of access to be provided to the subscriber from a visited network of a plurality of networks (12, 14, 16) connected to a home network (10); in response to the identification of the subscriber and an application level of access to be provided to the subscriber, storing a subscriber profile of the authorized application level of access to be provided to the subscriber; and controlling access of the subscriber to any network dependent upon a comparison of the application level of service to be provided to the subscriber and the stored subscriber profile.

A method, computer program, and apparatus for allowing endpoints to move between zones of a packet-switched network. In the invention, a communication between local and remote endpoints are established via a first gatekeeper, which services a first zone of the packet-switched network, when the local endpoint is at a location serviced by the first zone of the packet-switched network. When the local endpoint moves to a location serviced by a second zone of the packet-switched network, subsequent to the initial hand-off, communication between the local and remote endpoints is maintained via the first gatekeeper and a second gatekeeper which services the second zone of the packet-switched network, by performing an initial hand-off communication control functions from the first gatekeeper to the second gatekeeper. When the local endpoint further moves to a location serviced by a third zone of the packet-switched network, communication between the local and remote endpoints is maintained via the first gatekeeper and a third gatekeeper, which services the third zone of the packet-switched network, by performing a subsequent hand-off of communication control functions from the second gatekeeper to the third gatekeeper.

Methods and apparatus to manage voice service in evolved packet systems are disclosed. An example method in a User Equipment (UE) with a first indicator related to voice services in an Evolved Packet System (EPS) comprises receiving a Non Access Stratum (NAS) protocol response message with a second indicator and responsive to at least one of the first indicator or the second indicator, determining availability of voice services over IP Multimedia Subsystem (IMS) in at least one of long term evolution (LTE) or global system for mobile communications edge radio access network (GERAN)/universal mobile telecommunications system terrestrial radio access network (UTRAN).
摘要:
A system and method for enabling voice services using a network component in a communication system including a user equipment (UE) is provided. The UE is configured to receive a first message which may be a SIP request. The network component is configured to create a second message, or SIP request, based upon the first message. The network component further configured to subsequently receive a SIP response and select a subsequent action upon receiving the SIP response.
