  • Publication number: 20240112571
    Abstract: A congestion prediction device, a congestion prediction method, and a storage medium are provided. A mapping outputs an output variable when input variables are input to the mapping. The output variable indicates a degree of congestion in a predetermined specific area. The mapping is learned in advance by machine learning. The input variables include congestion variables. Each of the congestion variables indicates a degree of congestion in the specific area at regular time intervals within a specific period. The output variable indicates a degree of congestion after a lapse of the regular time interval from an end time of the specific period.

  • Patent number: 9900818
    Abstract: When a representative PS server receives a P-TMSI contained in a PDP context succession request signal from a UE according to a handover communication procedure prescribed in an applicable standard after the UE moves, if the PS server identified with the identification information contained in the received P-TMSI is not its own representative PS server, the representative PS server identifies the PS server identified with the identification information as a PS server that manages a femtocell base station to which the UE belonged before it moved and forwards the PDP context succession request signal to the identified PS server.

  • Patent number: 9860729
    Abstract: AS-B (810) measures a telephone call time from a time point when a telephone call, which is audio-originated by UE (100), starts. When a time obtained by subtracting the telephone call time from a time for which the UE (100) can telephone-call becomes a predetermined time, the AS-B (810) issues a multiplex instruction to FAP (200). When having received the multiplex instruction, the FAP (200) multiplexes a sound, which is based on a sound source file stored in advance, with audio data to be transmitted to the UE (100), and transmits the audio data, with which the sound has been multiplexed, to the UE (100).

  • Publication number: 20170164251
    Abstract: When a mobile terminal currently performing a voice communication or currently initiating a call by use of a VoLTE function moves from an LTE network to 3G femto-network, a GW (100) is connected to an MME (200) disposed on an access network in the LTE network and to an FAP (300) having an IMS-femtocell area as a communication area to be handed over the voice communication or the initiation of the call. When the mobile terminal currently performing the telephone communication or currently initiating the call moves from the communication area of the LTE network to the IMS-femtocell area, a call processing of the mobile terminal is caused to be handed over from the MME (200) to the FAP (300).

  • Patent number: 8649767
    Abstract: A Femtocell base station has a determination means and a transmission means. The determination means, upon receiving a location update request message from UE (User Equipment), determines whether a first message that prompts the UE to again attempt a location update should be transmitted to the UE, whether a second message that prompts the UE to divert to another network should be transmitted to the UE, or whether a third message that notifies the UE that the location update request is accepted should be transmitted to the UE. The transmission means transmits to the UE either the first message, or the second message, or the third message in accordance with the determination of the determination means.
