Abstract:
The invention relates to a method for providing a special-purpose key for securing a data link between a mobile terminal (MS) and a network access server (NWZS) of an access network (ZNW). According to said method, once the mobile terminal (MS) is successfully authenticated via the network access server (NWZS) and via at least one authentication proxy server of an authentication signal path (ASP) a non-special purpose universal key (K) is generated by an authentication server (AS) of the mobile terminal (MS). A derived key is derived from said universal key by at least one authentication proxy server along the authentication signal path (ASP) or by the network access server (NWZS) depending on a character string (ZK), which has at least one respective binding criterion (BK). Said derived key forms the special-purpose key that has a special purpose defined by the binding criterion (BK).
Abstract:
It is described a method for controlling an admission of a mobile station (MS) (220) to a femto access point (FAP) (210). The method comprises (a) receiving an access request message by an AAA server (250), wherein the access request message comprises a closed subscriber group (CSG) information being assigned to the FAP and wherein the access request message is indicative for an access request of the MS to the FAP, which is connected via a femto gateway (234) and/or via a FAP management system (132) to the AAA server, (b) performing an admission control by the AAA server, whereby the CSG information of the access request message is compared with admission control data being stored in the AAA, (c) returning a first access message from the AAA server to the femto gateway and/or to the FAP management system, wherein the first access message is indicative for a match or a missing match between the CSG information and the admission control data, (d) transmitting a second access message from the femto gateway and/or from the FAP management system to the FAP based on first access message, and (e) granting or refusing the access request to the MS by the FAP based on the second access message. It is further described an AAA server and a computer program for executing the described admission control method.
Abstract:
The invention relates to a method for providing service quality in a WiMAX communication network, and a method for selecting an access transport resource control function by means of a guideline decision-making function in a communication network. According to a method for providing service quality on an air interface (R1) of an access network (ASN) in a WiMAX communication network by means of an application function (AF), the application function aims to provide a user of the WiMAX communication network with a service quality-related application. The desired service quality is signalled by means of an authentication, authorisation and accounting infrastructure of the WiMAX communication network.
Abstract:
Method for providing an IP key, for encoding messages between a user terminal MS or a PMIP client and a home agent HA, wherein an authentication server only provides the mobile IP key when the authentication server recognises, by means of a correspondingly encoded parameter, that the user terminal MS itself is not using mobile IP (PMIP).

Abstract:
A method of connecting a mobile station to a communications network is provided. The method includes performing an authentication of the mobile station at the network. A secure identifier is received at a gateway node of the network and at an access node from an authentication node of the network if it is determined by the authentication that the mobile station is a subscriber to the network. The secure identifier is generated at the mobile station if it is determined by the authentication that the mobile station is a subscriber to the network. A first secure communications tunnel is established from the access node to the mobile station using a value of the secure identifier and a second secure communications tunnel is established from the access node to the gateway node of the network using the value of the secure identifier. The first and second communications tunnels are bound together to form a communications path between the mobile station and the network
Abstract:
A method of protecting an identity of a mobile station in a communications network is provided, where the communications network includes an access node and a gateway node. The method includes receiving a first mobile station identifier value at the access node, storing the first value in the access node, receiving a second mobile station identifier value, correlating the second identifier value with the first identifier value in the access node, sending the first and second identifier values from the access node to the gateway node over an interface, storing the first identifier value and the second identifier value in the gateway node, and correlating the second identifier value with the first identifier value in the gateway node.
Abstract:
It is described a method for performing an update of a closed subscriber group being assigned to a femto access point (210) of a telecommunication network, wherein the femto access point (210) is coupled to a femto access point management system (232). The method comprises (a) receiving by the femto access point management system (232) an update request for updating the closed subscriber group, (b) transmitting from the femto access point management system (232) an authorization request for updating the closed subscriber group to an authentication, authorization and accounting server (252, 254) or to a data base, (c) receiving by the femto access point management system (232) an authorization message for updating the closed subscriber group from the authentication, authorization and accounting server (252, 254) or from a data base, and (d) informing a mobile station (220) being connected to the femto access point (210) or to a macro base station (234) of the telecommunication network about a successful update of the closed subscriber group. It is further described a femto access point management system (232) for managing at least one femto access point (210).
