A method and apparatus for operating a femto-cell base station are disclosed. The femto-cell base station is configured to provide coverage to a User Equipment by connecting it to a core telecommunications network using a first frequency belonging to a first radio access technology. The method includes detecting that a fixed network connection of a femto-cell base station is not operative, and, in response to such failure, scanning frequencies in a second radio access technology available to a wireless network interface of the femto-cell base station, said second radio access technology being different than the first radio access technology. If there is any frequency available in said second radio access technology, said frequency in said second radio access technology is established as the operational frequency of a cellular wireless network connection established by the wireless network interface.

Method and controller device for controlling a plurality of N transport paths in RANs, wherein a primary path is assigned for each type of traffic to allocate voice or data calls, comprising: measuring load of the primary path periodically, when a call is incoming, comparing the measured load with a threshold, if the load of the primary path is less than or equal to the threshold, allocating the call to the primary path otherwise: calculating the available bandwidth of each transport path; comparing the available bandwidth of the primary path to the available bandwidths of the other transport paths and: if the available bandwidth of the primary path is greater than or equal to the available bandwidths of the others, allocating this call to the primary path; otherwise, allocating the call to a secondary path chosen from the remaining N−1 transport paths.

A method and apparatus for reconfiguring an operational frequency and associated bandwidth used by a femto-cell base station are disclosed. The femto-cell is configured to provide coverage to a User Equipment by connecting to a core telecommunications network via a gateway device. The method includes checking a list of frequencies and associated bandwidths available to a wireless network interface of the femto-cell base station and determining if any of the frequencies in the list matches the operational frequency supported by the User Equipment to which the femto-cell base station is providing coverage. If at least one frequency matches the one supported by the User Equipment, a second frequency is selected from the list of frequencies, said second frequency being established as the operational frequency of the femto-cell base station.
摘要:
Method and RNC for selecting transmission technology when a UE enters the network, which checks whether the UE is MIMO and, if so and only one carrier is available, allocates its traffic to said carrier and uses a S-CPICH to provide all MIMO traffic with a diversity pilot and Virtual Antenna Mapping for balance. If more than one carrier is available, the number of UEs, their radio conditions and load of carriers are checked periodically. If the carrier is busy only with MIMO and its load is higher than the load of the remaining carriers, diversity CPICH of STTD is selected; otherwise and only if the UEs vulnerable to STTD with good radio conditions exceed a certain number, the S-CPICH is selected. The RNC can reconfigure the network from transmitting MIMO traffic with STTD to using MIMO with S-CPICH or vice versa dynamically by periodical check of the load and UEs criteria for configuration change.

Fax transmission over a PLMN using a home gateway connected to the originating fax terminal equipment, comprising: sending a call setup request for a fax call destined towards a terminating fax terminal equipment, receiving at the originating fax terminal equipment a reply from the home gateway, sending every data from the originating fax terminal equipment to said home gateway and storing them in the home gateway, sending a call establishment request from the home gateway to the PLMN and at least one connection establishment request from the home gateway to the terminating fax terminal equipment, waiting for a connection establishment confirmation from the terminating fax terminal equipment within a configurable time, when the connection establishment confirmation is received, sending from the home gateway every stored data to the terminating fax terminal equipment through the PLMN and optionally a notification on the fax transmission status, at least provisional, to the originating fax terminal equipment.
摘要:
The present invention discloses a method for selecting a transmission technology (MIMO or non MIMO) for a HSDPA connection established between a RNC and a UE depending on the mobility of said UE, measured at the RNC as variations of the position of the UE. Then, if the connection is established with HSDPA MIMO technology and the position variations exceed a first pre-defined threshold, the connection is switched to HSPDA non MIMO technology. Also, if the connection is established with HSPDA non MIMO technology and the position variations are below a second pre-defined threshold, the connection is switched to HSPDA MIMO technology
摘要:
A cellular communication network is described wherein the power of the pilot channel transmitted by the base station is decreased when the uplink interference in its cell area increases above a threshold value. As a result the mobile terminals at the edge of the cell area are triggered to reselect to another base station and the number of call drops and failed call set-ups is reduced.

Base station apparatus (1) is provided for improving bandwidth usage in a cellular communication network serving at least one mobile terminal. The network is capable of supporting at least a first radio access technology (i.e. GSM) and a second radio access technology (LTE) and uses a predefined bandwidth range. The apparatus comprises a base band unit (3) including a counting means for determining the number of mobile terminals within a cell of the first radio access technology supporting the second radio access technology and a measuring means for determining the level of traffic carried by the first radio access technology cell; and a bandwidth assignment means for dynamically assigning a first portion of the bandwidth range to the first radio access technology and a second portion of the bandwidth range to the second radio access technology on the basis of the number of supportive mobile terminals and the level of first radio access technology traffic.In this way, the bandwidth assigned to GSM and LTE can be configured to take account of changes in the traffic levels and device capabilities in either RAT.

An economizer in a solar tower plant and operating method of said plant the purpose whereof is to make use of the heat from the heat losses generated around the solar tower receivers (3) to preheat the fluid with which the saturated steam or superheated steam solar receivers are fed. When the heat from the losses absorbed by the economizer (2) is not sufficient to achieve the necessary minimum temperature, a secondary economizer (4) is used which takes live steam (prior to it entering the turbine) and increases the temperature of the feed water of the receiver (3).
