An electrically insulating cross-arm for a tower for high-voltage power networks. The cross-arm includes an insulating structural member for attachment to the tower body and to support a conductor cable. The insulating structural member comprises a solid rigid spine extending along a long axis having cross sectional profile, normal to the long axis, having a second moment of area of its cross sectional profile about every axis normal to the long axis and dissecting its centroid has a value of A/2&#x3c0; or more, where A is the area of the cross sectional profile. The structural member provides resistance to bending and compressive buckling and allows conductors to be safely supported at reduced tower height. T and Y shaped cross sections provide water run-off and inhibition of organic growth. The structural members are also generally useful as insulator members in high voltage power networks.

A method of operating a user station in a cellular communications system. The method relates to determining and allocating a plurality of operating resources, including at least one processing resource and at least one cellular communications resource, to a plurality of applications. The method includes assessing application requirements with respect to the processing resources in association with the application's requirements with respect to the cellular communications resources. Also described is corresponding apparatus for operating a user station. Also described is a storage medium storing processor-implementable instructions and a signal carrying processor-implementable instructions.

Communication system and operating method thereof

A transcoder of a communication system is arranged to selectively embed (104) a data pattern into a call (102) to produce a slow-rate data channel in the call emanating from a switch. The data pattern includes a call identity that uniquely identifies how the call is routed through the communication system. In the event that transcoder detects (106) this call identity during subsequent routing of the call back to the switch, the transcoder identifies that the call can be routed directly through the switch and therefore instructs (112) the communication system to execute a local routing operation in which control information is routed throughout the communication system while traffic information generated in the call is routed directly through the switch, as illustrated in FIG. 4.

Method of local routing and transcoder therefor

To alleviate the constraints imposed on communication system management by the assignment of dedicated ranges of MSISDNs and IMSIs to each particular home location register (HLR.sub.1, HLR.sub.2, HLR.sub.N), the present invention provides an ability to separate IMSIs and MSISDNs between HLR platforms by providing at least two databases (80-90) separated from one another and indexed in terms of ranges of MSISDNs and ranges of IMSIs, as illustrated in FIG. 5. A cross-reference (92, 95) is both stored within a particular MSISDN and a particular IMSI to maintain an association therebetween, thereby allowing access to subscription information stored in at least one of the particular MSISDN and the particular IMSI.
