Abstract: An apparatus for enriching data records based on messages monitored on a telecommunications network having an Internet Protocol (IP) portion includes a data record enrichment module for receiving data records from a data record builder. The data records include at least a subscriber identifier field and a handset type identifier field and the data enrichment module stores a table mapping subscriber identifiers with the handset type identifiers. When a received data record includes a subscriber identifier and a handset type identifier, the table is updated appropriately and when the received data record includes the subscriber identifier but does not include the handset type identifier, the data record enrichment module checks the table for the handset type identifier mapped to the subscriber identifier and adds the corresponding handset type identifier, if it is present in the table, to the handset type identifier field in the data record.

Abstract: In a signalling network employing the SS7 signalling protocol, it is known to use masks to mine CDR stores in order to obtain data for analysis in respect of a particular customer of a communications network associated with the signalling network. However, the use of masks to mine the CDRs can result in the retrieval of unwanted CDRs or the omission of relevant CDRs. The present invention therefore provides a call monitoring apparatus that receives a CDR and accesses a reference database, comprising a list of customers and respective telephone numbers, in order to identify an association between the CDR and a given customer. Consequently, speed and efficiency of analysis of CDRs is increased.

Abstract: A data processing apparatus is coupled to receive call data records from a telephone network (4), for example an SS7 network. The apparatus (1) receives data records of different types having different formats. For each different type of data record, the apparatus (1) has a library (9, 10, 11 ) of type-specific functions associated with the particular type of data record. The apparatus (1) also has a set (8) of common functions available which contains functions that can be utilized for all types of data records, and for managing the system. Instructions are received by the apparatus (1), which indicate which type or types of data records are to be received and which functions are to be carried out on the data records. The apparatus (1) then creates a function list of the particular functions that are to be carried out before executing the particular functions on the received data records and then storing the processed records in a database (12, 13, 14).

Abstract: Liquid crystal compounds have been synthesized of general formula (I) and may be mixed with other liquid crystal compounds to give useful liquid crystal mixtures which may then be used in liquid crystal devices. Such devices include linear and non-linear electrical, optical and electro-optical devices, magneto-optical devices and devices providing responses to stimuli such as temperature changes and total or partial pressure changes. Formula (I) where each Z.sub.1-6 is given by formula (II), where Y for each of Z.sub.1-6 is independently COO, OCO, CH.sub.2 O and OCH.sub.2, m defines the number of substituents on each of Z.sub.1-6 and is independently 0-5,and X is independently for each substituent on each of Z.sub.1-6 alkyl (straight chain, branched and chiral), alkoxy (straight chain, branched or chiral), alkanoyl (straight chain, branched or chiral), alkenyl (straight chain, branched or chiral), halogen, halogenoalkyl (straight chain, branched or chiral) and CN, provided that at least one of Z.sub.
