  • Patent number: 8792914
    Abstract: A method and apparatus is disclosed whereby location based information (LBI) is used to make access and routing decisions within a network. Such LBI is sent from mobile devices to the core network when the mobile device registers with the network and is updated periodically. Over time, this collected LBI data represents the position of mobile devices over time and periodic patterns of usage in different geographic areas. When a network receives an indication that a mobile device requires registration with the network, the network determines as a function of said LBI, a desired network access technology to use to connect said mobile device with the network. Instructions are then transmitted to the mobile device to establish a connection using said desired network access technology and the device is registered with the network. Dynamically updated LBI information from mobile devices is also used for IP network routing optimization.

  • Patent number: 8781476
    Abstract: A cell change procedure for user equipment (UE) situated in a serving cell. An active set of cells comprises a list of cells to which the UE can move from the serving cell. The UE sends a request to a network controller to add at least one further cell to the active set. The UE then receives the requested active set update from the network controller with the further cell and a list of cells to which a modified cell change procedure shall be used for handover. A neighbor cell which is stronger than a current serving cell is detected. This detected stronger neighbor cell is matching with the received list of modified cell change procedure cells, and the modified cell change procedure for the handover to the stronger neighbor cell is applied if the stronger neighbor cell is found matching a cell on the list.

  • Patent number: 8781478
    Abstract: In a handover control apparatus, a terminal is wirelessly connected with one of base stations to establish a wireless data communications connection. The terminal executes a handover process using a handover process section when an electric wave state becomes lower than a threshold value, which is variable. The threshold value can be adjusted according to a moving speed of the terminal. Furthermore, the threshold value is corrected according to the past electric wave state. The threshold value is corrected according to a difference of (i) a minimum electric wave state in a preceding handover process, and (ii) a lower limit. The correction is executed so as to reduce an excessive decline of an electric wave state in a succeeding handover process. Deterioration of a communications quality during a handover process can be thereby suppressed.

  • Patent number: 8699463
    Abstract: A femtocell base station 10a suspends transmission and reception of radio waves to and from a radio communication terminal 30 of an accommodation object when the radio communication terminal 30 is not in the neighborhood of the femtocell base station 10a. The femtocell base station 10a determines whether the radio communication terminal 30 is in the neighborhood of the femtocell base station 10a based on information of a UATI update notification provided through another base station in communication with the radio communication terminal 30 and, when the radio communication terminal 30 is in the neighborhood of the femtocell base station 10a, starts receiving the radio waves from the radio communication terminal 30.

  • Patent number: 8688119
    Abstract: When a user equipment (UE) is in a CONNECTED state with a base station of a wireless network and is also in a discontinuous reception (DRX) mode, a DRX parameter such as DRX period for the UE is compared with a threshold. If the DRX parameter is at or below the threshold, the UE applies a network controlled mobility mode with UE assist where the network controls handover of the UE to another cell. If the DRX parameter is above the threshold, the UE applies a UE controlled mobility mode in which the UE is free to select a best cell. In this way, DRX benefit of reduced power consumption is maintained while the time period in which the UE is unreachable is minimized.

  • Patent number: 8688123
    Abstract: A method for transmitting a mobility state is provided in the present invention, the method includes: when an source evolved NodeB (eNB) performs a handover of a user equipment (UE) in a connectivity state, it sends the UE historical information to a target eNB; the target eNB decides a mobility state of the UE according to the UE historical information. Alternatively, when the source eNB performs a handover of the UE in a connectivity state, it decides the mobility state of the UE according to the UE historical information, sets the corresponding mobility state instruction information and sends it to the target eNB; the target eNB acquires the mobility state corresponding to the UE according to the received mobility state instruction information. A system for transmitting a mobility state is also provided in the present invention.

  • Patent number: 8688127
    Abstract: An inter-frequency handoff of a mobile station engaged in a call via wireless network is effected by gradually changing a carrier frequency of a forward link signal from a first-channel frequency, corresponding to a first frequency channel, to a second-channel frequency, corresponding to a second frequency channel. Initially, a first transmitter in the wireless network transmits the forward link signal in the first frequency channel. A second transmitter then transmits the forward link signal while changing the carrier frequency from the first-channel frequency to the second-channel frequency at a specified tuning rate. The tuning rate may be dynamically adjustable in response to requests from the mobile station. Once the second-channel frequency is reached, a third transmitter continues transmitting the forward link signal in the second frequency channel. The mobile station may also gradually change the carrier frequency of the reverse link signal that it transmits for the call.

  • Patent number: 8676213
    Abstract: A user equipment UE reports its mobility state in signaling for establishing, re-establishing, or re-configuring a radio connection between the UE and a network access node. In one embodiment the reported mobility state is selected from among normal; medium and high. In another embodiment the reported mobility state informs of a number of cell changes the UE has performed within a predetermined evaluation period. The UE may also include an indication whether a hysteresis period for entering into a normal mobility state is running for the UE. The network configures the UE in dependence on the reported mobility state, such as setting a parameter for measuring or reporting neighbor cells (e.g., suspend a serving cell quality threshold as a condition for measuring/reporting; limit inter-frequency and/or inter-radio access technology reporting; set a shortest measurement, reporting gap; disable an event trigger; and/or set layer 3 filtering of measurement results for faster reporting).
