Abstract: A method of operating a network message interceptor for enforcing an authentication policy for communication over a network between first and second network endpoints, the interceptor being in communication with the network and external to the first and second endpoints, the network including transport layer security, the method comprising the steps of: intercepting a handshake message transmitted over the network between the first and second endpoints; extracting a certificate for an authenticating one of the endpoints from the handshake message; determining a validity status of the certificate for confirming an identity of the authenticating endpoint; and preventing communication between the first and second endpoints based on a negatively determined validity status of the certificate.

Abstract: Method and system are provided for optimisation of mobile data communication using byte caching. The method includes: intercepting data communications at a base station, wherein the data communications are between a user equipment and a network; and implementing byte caching at the base station to optimise data transfer between the base station and a byte cache server in the network at a peering point; wherein the network containing the base station supports mobility management of data transfer to and from the user equipment. The method includes providing a byte cache server as a transparent proxy with byte caching functionality where traffic for the user equipment is no longer tunnelled.

Abstract: Method and system are provided for object caching with mobility management for mobile data communication. The method may include: intercepting and snooping data communications at a base station between a user equipment and a content server 501 without terminating communications; implementing object caching at the base station using snooped data communications 502; implementing object caching at an object cache server in the network 503, wherein the object cache server proxies communications to the content server from the user equipment; and maintaining synchrony between an object cache at the base station and an object cache at the object cache server 504. An object cache may be maintained at each base station in the mobile network which is consistent with an object cache at the object cache server. The object cache at each base station may be of fixed size, with the object cache at the object cache server of a size equal to the sum of all the base station object caches, and the object cache at the object cache server may be partitioned so that the object cache server can separately manage the objects cached for each base station. The communication may be HTTP requests and responses.

Abstract: A system for verifying the location of a mobile device is disclosed in which the mobile device is associated with a mobile communications network and interacts with a server application program requiring verification of the geographical location of the mobile device. In particular, a mobile device requests a secure location verification message from a mobile communications network. The mobile communications network then returns a digitally secured message containing location and identification information for the mobile device. The mobile device can then send this location verification message to a third party application program to verify its current position. This allows a third party application to verify the current location of a mobile device before allowing/denying it access to the application.

Abstract: A method for moving OSI layer 4 connections (such as Transport Control Protocol TCP) seamlessly between wireless User Equipments (UE) connected to a series of cell towers in applications where the connection is extracted out of the underlying cellular protocols at the towers. On detecting that a UE with a broken-out layer 4 connection has moved from a first to a second cell tower, traffic for an existing connection from the UE is tunneled between the first cell-tower and the second cell-tower. On identifying a predetermined trigger event, which may be natural or forced quiescence at the terminal, an ongoing bidirectional flow of packets is migrated to the second cell-tower.

Abstract: In a method for caching video object portions, a request for stand-­alone content in a video object (202, Figure 2) is received 502, the content neither being cached nor adjacent a cached video portion, and a first portion of the video object is cached 504. A value (e.g., relating to popularity, age, etc) is assigned 506 to the first video object portion. A subsequent request for content in the video object is received 508, the subsequent request corresponding to access to the first video object portion and a second, uncached portion (such as segment 212, Figure 2) of the video object. The value of the first video object portion is updated 510. Then, for the second video object portion, an amount to cache and a value are determined 512, e.g. based on video object value, available storage, or the size of the second portion. Thus, a method of partial caching of large video objects is provided, increasing the cumulative hit rate of edge caches and lowering traffic; only popular video segments may be cached, and already-cached video chunks may be split or divided (306e, 306f: Figure 3). The subsequent request may ascertain overlaps with cached data.
