Abstract: A method of controlling location information of subscribers (210, 212, 222) in a wireless, ad-hoc communications network (200). The network (200) comprises a plurality of nodes (204, 216, 226), wherein at least portion of said nodes are provided with Home Location Registers (HLRs) (206, 218, 228) and each of said nodes (204, 216, 226) has a Visitor Location Register (VLR) (208, 220, 230). When an operation of a first node (216) is to be reconfigured at least a part of records from a first HLR (218) assigned to said first node (216) are transferred to at least one of the other nodes (226) of the network (200).

Abstract: A method of encrypting information to be transmitted by a transmitting terminal in a communication system providing secure communications between a plurality of terminals employing an encryption protocol that uses a shared encryption key in each of the plurality of terminals, the method including modifying the share encryption key in the transmitting terminal to provide a modified encryption key and encrypting the information to be transmitted using the modified encryption key, characterised in that the share encryption key is modified by combining with the shared encryption key identifier code used in the communication system to identify the transmitting terminal. A corresponding method of decryption and a system and mobile radio terminal using the method are also described.

Abstract: A cellular communication system includes a plurality of mobile stations and a system infrastructure operable to support communications between the mobile stations, the infrastructure being organized in a plurality of cells such that each of the mobile stations is served by a selected one of the cells, wherein each of the mobile stations is operable to select for service for group communications with a pre-defined group of the mobile stations a cell which is in a list of preferred cells (HLA) selected by the infrastructure according to a distribution of mobile stations of the group among cells serviced by the infrastructure, wherein a processor of the infrastructure is operable dynamically to update the list of preferred cells according to current system conditions and to notify mobile stations of the group of the updated list. Also described is a mobile station and a method for operation in the system.

Abstract: A TDMA communications system has a main carrier and at least one secondary carrier, each carrier having timeslots which may be used as traffic channels. The first timeslot of the main carrier is reserved for the main control channel whilst the other timeslots are, when traffic loading allows, reserved for synchronisation words (SYNC) and system information (SYSINFO), thereby enabling, for example, mobile phones to quickly synchronise with base stations. In an attempt to keep the main carrier timeslots free, channels are allocated to the carriers according to a predefined sequence, whereby an attempt is first made to put traffic onto the secondary carriers, the main carrier only being used if this attempt fails. Also mentions "freeing-up" the main carrier's traffic carrying timeslots, when timeslots become available on the secondary carriers, by reallocating them to the secondary carriers.

Abstract: A cellular communication system (100) includes a plurality of mobile stations (109, 111) and a system infrastructure (103, 157) operable to support communications between the mobile stations, the infrastructure being organized in a plurality of cells such that each of the mobile stations is served by a selected one of the cells, wherein each of the mobile stations is operable to select for service for group communications with a pre-defined group of the mobile stations a cell which is in a list of preferred cells (HLA) selected by the infrastructure according to a distribution of mobile stations of the group among cells serviced by the infrastructure, wherein a processor (161) of the infrastructure is operable dynamically to update the list of preferred cells according to current system conditions and to notify mobile stations of the group of the updated list. Updates occur when a mobile station of the group has been unable to receive service from a cell in the preferred list and is receiving service from a cell not on the list, the update thereby including that cell in the updated list.
