摘要:
The present invention proposes a method for data transmission in a cellular telecommunication system, in which system data are transmitted in units of bursts, each burst occupying a time slot (TS[j]) of one of consecutive frames (F[i]), each respective frame comprising a predetermined number (n) of time slots (TS[j]), j={(0, . . . , n−1}), and, within a single time slot (TS[j]) of each frame (F[i]), data can be transmitted between a first transceiver device (BS) and a respective one of a plurality of second transceiver devices (MS) in a first transmission direction (DL) from said first transceiver device (BS) to said respective second transceiver device (MS) or in a second transmission direction (UL) from said respective second transceiver device (MS) to said first transceiver device (BS), wherein during a first frame (F[i]) of consecutive frames respective second transceiver devices (MS) perform transmission with said first transceiver device (BS) during a time slot (TS[k]) assigned thereto for transmission, and during a subsequent second frame (F[l=1]) of said consecutive frames, respective second transceiver devices (MS) perform transmission with said first transceiver device (BS) during a different time slot (TS[1]) assigned thereto for transmission, with 0≦k, 1≦n−1 and k#1.

The invention relates to a telecommunication system and a method for matching the numbering schemes of telecommunication systems. The telecommunication system comprises a transmission network comprising at least one mobile exchange (MSC1, MSC2) associated with a subsystem (BUC, BU1-BU6), the calls of subscribers (MT1-MT6) in the subsystem being routed through the transmission network and the mobile exchange. A numbering scheme of the subsystem comprises an X-bit binary subscriber identity code (PID) and a numbering scheme of the transmission network comprises a Y-decimal subscriber identity code (MSIN). In the transmission network the subscriber (MT1-MT6) of the subsystem is assigned a Y-decimal identity code comprising a decimal number derived from the X-bit binary identity code of the subscriber and having no more than Y-1 decimals. At least one system identification decimal is introduced into the obtained decimal number at a predetermined position to indicate that the identity code belongs to the subscriber (MT1-MT6) of the subsystem.

A method, a mobile communication system and a controller controlling the use of the radio resources of the mobile communication system, by means of which it is decided when the optimization of the lu link between a mobile switching centre and the controller is triggered. In the method, history data is maintained (204, 205, 206, 214) on the roaming of the mobile station, at least on condition triggering the link optimization is set based on the history data, a check is made in response to updating the history data to see if the condition is fulfilled (207), and if the condition is fulfilled, the link optimization is triggered (208,209,210).
摘要:
The idea of the invention is the allocation of transmission resources in several separate steps. In the first step, the available transmission resources are dynamically divided between the different networks. In the second step, the networks divide the resources that have been allocated for their use among their users by their own channel allocation methods. In one embodiment, a given minimum capacity wherewith the network achieves a predetermined minimum quality of service is permanently allocated to some or all of the networks. As the capacity requirement increases, the necessary amount of additional capacity is allocated to the operator in excess of this minimum capacity. The additional capacity is then allocated either from resources separately reserved for this purpose that are common to the networks, or by borrowing it from capacity that is allocated to another network but falls outside the minimum capacity of said network. In accordance with one embodiment, an upper limit is set for the transmission capacity allocated to a network, in excess of which no capacity can be allocated to the network. The dynamic distribution of capacity between networks can be realized either in a centralized or in a distributed manner. If the division is performed in a distributed manner for example in such a way that each network independently allocates a band to itself, the algorithms used in the different networks must be compatible.
摘要:
A method for location updating in a cellular radio network. The network stores subscriber data permanently in a home location register (HLR) and temporarily in visitor location registers (VLR) integrated with mobile services switching centers (MSC). In connection with a call setup, the HLR requests the VLR to provide routing information for the subscriber, whereafter the inbound call is routed to the pertinent MSC and the subscriber is paged by the radio path. The network updates the location of the subscriber by check paging performed as a background run at suitable times.
摘要:
A method for carrying out a location updating from a mobile cellular radiophone system, such as a DECT system, to another cellular radiophone system, such as the GSM mobile phone system. In order to enable trunking of an incoming call to a terminal of a mobile system and also to obtain such a method for carrying out the location updating as ensures, as well as possible, a compatible information content in the networks, the method includes the following steps: (a) when the location area of the other system changes, the change is signalled to the mobile system, (b) an instruction is transmitted from the mobile system via radio path to the terminal of the mobile system to initiate an internal update procedure of the mobile system, and the internal update procedure of the mobile system is carried out in which the terminal of the mobile system transmits to the mobile system an indication of its presence, which step (b) is carried out in respect of at least one terminal of the mobile system, (c) the internal update procedure of the other radiophone system is carried out by the mobile station of the other radiophone system in respect of the at least one terminal of the mobile system, and (d) the procedure is continued from step (b) in respect of the terminals of the mobile system not yet updated.
