| 20120113840 | METHOD AND SYSTEM FOR ENHANCED TRANSMISSION IN MOBILE COMMUNICATION NETWORKS - Method and system for improving the performance of mobile communication networks. The method and system employs the additional functionality whereby an additional phase offset can be applied to one of the physical paths (one physical antenna) in order to modify and adapt the transmit polarization. In the preferred embodiment, the criterion for selecting the additional phase offset will be to maximize the energy received from the HSPA serving cell by the legacy HSDPA user equipments. | 05-10-2012 |
| 20120108229 | PROVIDING LOCAL TRAFFIC IN A CELL OR GROUP OF CELLS OF A CELLULAR COMMUNICATION NETWORK - A network component for a cellular network. The cellular network includes a plurality of access nodes covering a cell area and an access control node common to all access nodes for controlling the provision of traffic. The network component includes a communication manager and a classifier for classifying users of the cellular network into a first group of users and a second group of users. The communication managers checks if a call or an SMS is set up by a user belonging to the first or second group of users, takes control over calls and/or SMSs set up between users of the first group of users, and passes control to the access control node of the remaining calls and/or SMSs. | 05-03-2012 |
| 20120106331 | OPTIMIZING SIGNALLING LOAD IN A CELLULAR COMMUNICATION NETWORK - The invention relates to a cellular communication network serving mobile terminals or devices and how to reduce the signalling load in said network by introducing an auxiliary device which holds data packets in order to minimize connections according to a pre-determined rule. | 05-03-2012 |
| 20120015650 | FALLBACK BETWEEN RADIO ACCESS TECHNOLOGIES - A method for assigning a location area to a mobile device for use in circuit switched fallback from a first radio access network to a second radio access network. Two counters are implemented at the eNode B—a first counter to count the numbers of times a mobile reports a given last-used location area code and a second counter for counting the numbers of certain unique combinations of location area code and further identifying data. Whenever the eNode B receives a signal incorporating a location area code, checking the respective first counter for that code and conditionally incrementing the first counter such that if the first counter is below a predefined threshold the first counter is incremented. If the first counter is equal to the threshold, obtaining further identifying data in addition to the location area code and incrementing the corresponding second counter. | 01-19-2012 |
| 20120003976 | COMMUNICATION NETWORK SELECTION - A mobile telecommunications device includes cellular communication means for communicating with a cellular telecommunications network base station, wireless communication means for communicating with a wireless access point, and control means for selectively enabling the wireless communication means in response to a trigger. The trigger may be the launch of a web browser of a request for a download of data. | 01-05-2012 |
| 20110287765 | OPERATION OF MACHINE-TYPE COMMUNICATION DEVICES - The invention relates to operating a Machine-Type Communication (MTC) device for communication with a cellular radio network. A transmission is made from the MTC device to the cellular radio network to register the MTC device with the cellular radio network. The transmission includes a message from the MTC device to the cellular radio network, identifying the MTC device as an MTC device to the cellular radio network. Also, the MTC device has an associated HPLMN. An instruction is received at the MTC device from the network not to make a transmission from the MTC device for accessing the network. The instruction specifies a criteria for the MTC device's HPLMN or preferred list of networks. The MTC Device compares the criteria with the HPLMN associated with the MTC device and avoids making a transmission to access the network for a period of time based on the result comparing step. | 11-24-2011 |
| 20110275369 | TELECOMMUNICATIONS NETWORKS - An arrangement for determining radio coverage provided by a telecommunications system to a user of a mobile device is disclosed. In the case of a GSM or UMTS mobile device, if the device is in the idle mode (step A) and if a paging operation is not scheduled (step B), the mobile device records and stores on the mobile device a characteristic of the radio coverage provided when the mobile device is at each of a plurality of locations visited by the user of the mobile device (step C). The arrangement also enables retrieval of the recorded and stored characteristic so that radio coverage provided to the device for the user at the locations can be evaluated. If the telecommunications system includes a plurality of networks, the mobile device will record and store the characteristic for each of the plurality of networks. The arrangement then enables the radio coverage provided by the respective networks to be evaluated, and an informed choice as to the best network for that particular user can be made. | 11-10-2011 |
| 20110222450 | TELECOMMUNICATIONS SYSTEM AND METHOD - In a telecommunications network including a mobile terminal configured to operate in at least one active state and an idle mode, a network element for, and method of, managing the mobile terminal's duration of operation in the least one active state, which determine a parameter relating to the mobile terminal or a user of the mobile terminal; allocate an state transition timer with a particular duration in dependence upon the parameter; and transition the mobile terminal to a lesser active state or idle mode upon expiry of the state transition timer. The active states are preferably the RRC states of CELL_DCH, CELL_FACH, URA_PCH and CELL_PCH and the parameter is preferably a Quality of Service indication such as subscriber classification. | 09-15-2011 |
| 20110176485 | CIRCUIT SWITCHED FALLBACK - A method for performing Circuit Switched Fallback of a radio access terminal in a multi-RAT network environment comprised of a packet switched network and one or more circuit switched networks, each of said networks including a plurality of cells and the radio access terminal camping on a serving cell in the packet switched cellular network, the method comprising; receiving a service indication for a circuit switched service; transmitting to the radio access terminal a message to release the radio connection in the packed switched network; wherein the message to release the radio connection from the packet switched network comprises: data identifying one or more carrier frequencies associated with one or more of the circuit switched cellular networks; and system information data of a plurality of cells associated with one or more of the circuit switched cellular networks to the radio access terminal; releasing the radio access terminal from the packet switched cellular network; and in the radio access terminal, using the one or more carrier frequencies and the system information data of a plurality of cells to access a cell of the one or more circuit switched networks. | 07-21-2011 |
