Abstract: An apparatus includes least one processor and at least one memory including a computer program, the at least one memory and the computer program operable to, with the at least one processor, direct the apparatus at least to: identify a mobile station (MS) as a tunneling protocol endpoint; and configure an access bearer for the MS to prevent activation of a path management procedure for an entire data session; wherein the path management procedure comprises at least one of echo request messages, echo response messages, and version not supported messages.

Abstract: An apparatus is disclosed which according to an embodiment is configured to store a direct tunnel context. The direct tunnel context comprises a field or flag indicating whether or not a direct tunnel is established between the apparatus and a radio network, and further comprises at least one of a tunnel endpoint identifier and an address of a user plane of a serving node. The direct tunnel context optionally further comprises at least one of a tunnel endpoint identifier and an address of a user plane of a controller of the radio network. The apparatus may be a gateway or a gateway general packet radio service support node. The invention further provides a method, system, device and program suitable or configured to handle such direct tunnel contexts.

Abstract: The invention relates to a method for classifying traffic flows in a packet-based wireless communication system, said packet-based wireless communication system comprising at least one radio access network and a packet-domain core network, said method including the step of analyzing at least one data packet of at least one traffic flow through deep packet inspection at the level of the core network in order to classify the traffic flow. In order to save resources by enabling selective deep packet inspection, it is proposed that the method further comprises the steps of determining whether or not a data packet relates to at least one context out of a set of predetermined critical contexts, wherein the context is a function relating data packets to selected users, selected areas, and/or selected services, and selecting the at least one data packet for deep packet inspection if the data packet relates to one of said predetermined critical contexts.

Abstract: Embodiments provide a method and apparatus configured to store at least one record which comprises information on an address of an access point and on the type of the access point. The method or apparatus may return the information on the address and on the type of the access point in response to a query request requesting the address of the access point. The apparatus may be a domain name server.
