Abstract: Disclosed is a large-angle LED lens including a main body which has an incident surface on the inner side of the main body and an exit surface on the outer side thereof. The surfaces are provided symmetrically about the central axis of the main body. The incident and exit surfaces are transparent concave and convex surfaces, respectively. The maximum thickness d1 of the main body at the lower part and the minimum thickness d2 thereof at the top satisfy the relation: 4<d1/d2<6; the concave depth h1 of the concave surface and the thickness d2 satisfy the relation: h1>4*d2; and the convex height h2 of the convex surface and the thickness d2 satisfy the relation: h2>5*d2. With the disclosure, the light-emitting angle is increased while maximizing the utilization of the light. A large-angle emission LED light source module is also disclosed herein.

Abstract: The present invention relates to a method and apparatus for event analysis in a communication (telecommunication or computer) system. In particular, the invention relates to a method and apparatus for analysing events representing activity in the communication system. Embodiments provide a progressive technique for the analysis of the operation of a communication system. Embodiments provide a bottom-up approach by first detecting burst of events, and establishing causal relationships between events and system operation reports using detected event burst records representing the occurrence of burst behaviors in events in a system. Based on the causal relationships found, causes of a change in system operation may be identified by determining parameters associated with events of an event burst relevant to the change in system operation.

Abstract: A method of monitoring broadcast or multicast streaming service in a communications network comprising collecting (102) quality feedbacks related to the streaming service, determining (106) a maximum distance to a neighbour in a cluster and a minimum number of values required to form a cluster (106). The method further comprises grouping (108) collected values from the feedbacks into clusters based on the maximum distance to a neighbour in a cluster and the minimum number of values required to form a cluster and then mapping (112) the clusters onto topology of the network and determining (114) location of a problem causing degradation of the service.

Abstract: The invention relates to selective caching in a packet network and to packet loss repair in a packet network using selective caching of packets. The invention provides a method of selective caching at an intermediate node in a packet network during a packet transfer session between a sending node and at least one receiving node via the intermediate node in which packet caching is initiated depending on at least one service quality factor related to the packet transfer service provided by a transfer path between the intermediate node and at least one receiving node during the transfer session. The invention also provides a method of packet loss repair using packets cached at an intermediate node.

Abstract: User equipment uses traces of service primitives of one or multiple service sessions to automatically discover a service sequence. Service sequences are refined by analyzing sequences captured during multiple sessions of the same service. A daemon receives from a plurality of user equipment the observed service sequences. The sequences from different user equipment are aggregated. The daemon sends back the refined service sequences to user equipment. User equipment sends a problem report to the daemon and/or a service monitor in the case of a service failure. The daemon or the service monitor aggregates such problem reports and discovers the causes of service degradations.

Abstract: A network node comprising at least one network interface the network node arranged to form network links to other network nodes through the or each network interface, each network link being to a neighbouring one of the other network nodes, the network node arranged to determine whether data transmitted over the links to the relevant neighbouring network nodes is successfully received. Should the network node make a first determination that data sent over a given network link to a neighbouring node has not been successfully received, the network node temporarily disables the entry for that network link in a memory for a period of time, such that the network node does not send data to the neighbouring node over the given network link during the period of time, but then subsequently re-enables the entry after the period of time has elapsed.

Abstract: A method of monitoring performance of a telecommunications network transmitting in real time multimedia data from a content provider to a device operating in the network is disclosed. The method comprises the steps of receiving said multimedia data; collecting information about the connection used to receive the multimedia data; producing a receiver report; appending said report with an identifier of a segment of the telecommunications network in which the device operates and transmitting said report to said telecommunications network.

Abstract: A method of adjusting a routing table update interval in a node of an ad-hoc radio telecommunications network comprising: reducing the routing table update interval by dividing it by a first constant value if a local change in the network is detected by the node. If a remote change in the network is detected by the node a rate of routing table exchange is increased by a second constant value. If no network change is detected by the node the rate of routing table exchange is reduced by the second constant value, wherein the rate of routing table exchange is reciprocal of the routing table update interval.
