摘要： Methods for establishing secure point-to-point communications in a trunked radio system include receiving, at a trunking controller, a request from a source endpoint for a traffic channel for confidential communications between the source endpoint and a destination endpoint using a shared unique first symmetric key. The trunking controller provides keying material related to the symmetric key over the secured control channel to at least one of the source or destination endpoints and assigns a traffic channel. Moreover, in response to the request, the controller assigns a traffic channel. The keying material enables the unique first symmetric key to be securely established between the source and destination endpoints.

摘要： A method and apparatus for attaching a wireless device to a foreign wireless domain of a 3GPP communication system using an alternative authentication mechanism, wherein wireless device performs the method, which includes: sending a first attach request message to an infrastructure device in the foreign wireless domain; receiving an attach reject message from the infrastructure device upon an unsuccessful attempt to obtain authentication credentials for the wireless device from a home wireless domain of the wireless device using a standard 3GPP authentication mechanism; responsive to the attach reject message sending a second attach request message to the infrastructure device, wherein the second attach request message indicates an alternative authentication mechanism to the standard 3GPP authentication mechanism; and receiving an attach accept message from the infrastructure device when the wireless device is successfully authenticated using the alternative authentication mechanism.

摘要： A method for minimizing tunnels in a network, apparatus and computer-readable storage medium having computer readable code stored thereon for programming a computer to perform the method. The method includes the steps of: obtaining state information associated with a first node connected to a mobile network behind a mobile node; receiving a first message sent between the first node and a correspondent node, wherein a first header was removed from the first message prior to sending the first message; recreating, in one of the mobile node and a mobility agent, the first header using the state information; and sending the first message with the first header.

摘要： A method for obtaining authentication credentials for attaching a wireless device to a foreign wireless domain in a 3rd Generation Partnership Project (3GPP) communication system, which includes: receiving an attach request message from the wireless device; and responsive to the attach request message, authenticating the wireless device and retrieving a set of authentication vectors, wherein the authentication vectors are for authenticating the wireless device to the foreign wireless domain. The method further includes encrypting the set of authentication vectors using a first security key of a home wireless domain of the wireless device. In addition, the method includes encrypting the first security key using a second security key of the foreign wireless domain and sending the encrypted set of authentication vectors and the encrypted first security key to the wireless device.
