  • Publication number: 20230422018
    Abstract: Method and arrangement for collecting subscriber identity is presented. A communication intelligence cell is formed for carrying out uplink and downlink communication with cellular mobile devices. The cell is connected to the identity query interface of the cellular network operator. An encrypted subscriber identity of the cellular mobile device is received from a mobile device. A radio connection to the mobile device is closed. A second registration request with a temporary identity of the cellular mobile device is received from the mobile device. An identity query with the temporary identity of the mobile device is transmitted to the identity query interface and permanent identity of the mobile device is received from the query interface.

  • Publication number: 20230300896
    Abstract: Base stations, system, methods, and computer programs are disclosed to implement two successive or simultaneous ad hoc (Long-Term Evolution) LTE cells. The successive LTE cells are set up successively on a same channel number but with different Physical Cell IDs (PCID) and Tracking Area Codes (TAC). The simultaneous LTE cells are set up simultaneously on different channel numbers, and with different PCIDs and TACs. A radio connection is set up in the ad hoc LTE cell to an LTE user apparatus, and a Non-Access Stratum (NAS) timer is set simultaneously. The following is repeated until a predetermined period of time remains before an expiry of the NAS timer: commanding the LTE user apparatus to use full buffer in all uplink messages; forcing the LTE user apparatus to send uplink messages; and receiving a reply message from the LTE user apparatus.

  • Publication number: 20230105088
    Abstract: An ad hoc radio base station obtains information regarding existing 5G NR SA cells; for each existing cell, performs an analysis by detecting a frequency of a synchronization signal block, of the existing cell from the information, decoding a radio frequency, bandwidth of the existing cell from the information, and measuring a reference signal received power of the existing 5G NR SA cell. The station also sets up an ad hoc 5G NR SA cell based on the analysis.

  • Patent number: 11240808
    Abstract: Methods and arrangements are disclosed for collecting subscriber identity. A cell is formed for carrying out communications with mobile devices. A channel bandwidth indication is transmitted and indicates to cellular mobile devices the formed cell utilizes bandwidth identical to the bandwidth utilized in neighboring real cells. A downlink radio channel power level on a given continuous channel subset of the indicated channel bandwidth is provided. A communication request from a cellular mobile device is received and radio resources allocated to the cellular mobile device from the given continuous channel subset of the indicated channel bandwidth. A subscriber identity of the cellular mobile device is received from the cellular mobile device.

  • Patent number: 9167456
    Abstract: Subscriber terminal identification is disclosed. An apparatus controls a base station to form an emulated long term evolution LTE cell such that tracking area code and physical cell identity of the emulated LTE cell are unused by real neighboring LTE cells, and radio frequency power level of the emulated LTE cell within the emulated LTE cell is higher than the radio frequency power levels of the real neighboring LTE cells within the emulated LTE cell; and controls the base station to receive a connection request from a subscriber terminal residing in the emulated LTE cell, whereupon, in the ensuing exchange of messages, the base station is controlled to receive an international mobile subscriber identity from the subscriber terminal.
