The invention discloses a wireless communication system and a mobile management method. And the wireless communication system comprises first wireless network and second wireless network, where the location area marks broadcasted by the first and second wireless networks are the same, and received by mobile terminal so as to make the mobile terminal in idle mode not initiate any location updating flow when roaming between the first and second wireless networks; and the configuration information of at least one support node of the core networks of the first and second wireless networks is set with information of expressing preferred network.

When a terminal enters a cell of a personal-use base station (NBTS) arranged in a certain location area, the terminal receives a location area identifier having a number that is different from an identifier of the location area, and transmits a location updating request with the reception of the location area identifier as a trigger. On receiving the location updating request, a VLR or an NRNC having a registration table, in which the ID of the personal-use base station and the ID of a terminal allowed to use the personal-use base station are registered, judges whether the terminal issued the location updating request is the terminal allowed to use the personal-use base station by referring to the registration table. If the terminal issued the location updating request corresponds to the terminal allowed to use the personal-use base station, the terminal is placed under a status where it is capable of performing communication in the cell, and if not, the terminal is placed under a status where it is incapable of performing communication in the cell.

In one of multiple mobile communication networks, a serving node responsible for locating mobile terminals is responsive to a registration request from a mobile terminal for storing the serving node identity in a home location database to which the mobile terminal is subscribed. In response to a location request message from a client terminal requesting the location of a target mobile terminal, a serving node identity is retrieved from the home location database of the target mobile terminal. The serving node identity represents the current location of the target mobile terminal. If the current location area is within the coverage area of location-based service provided by the client terminal, the location request message is forwarded to a serving node identified by the retrieved serving node identity. Otherwise, an error message is transmitted to the client terminal to indicate that the target mobile terminal is roaming outside of the coverage area.

The location of a mobile unit is determined by evaluating the instantaneous distances between an apparatus traveling above the surface of the earth and the mobile unit. The instantaneous distances are determined by measuring the travel time of a plurality of signals and calculating the distance based on the speed of the signal. One of two possible location regions is identified as the region including the location of the mobile unit by observing the motion of the mobile unit resulting from the rotation of the Earth.

A mobility management entity (MME) for setting up a call includes a first network interface which receives a tracking area update (TAU) request from a user equipment (UE). The MME includes a processing unit which translates the TAU request into a location area update (LAU) request. The MME includes a second network interface in communication with the processing unit which sends the LAU request to a mobile switching center (MSC) selected as a tracking MSC thereby establishing the MME as a network node through which the UE is paged. The second network interface receiving a LAU response from the tracking MSC that includes at least information identifying one or more suitable location area identifiers (LAI(s)) to which handover is allowed and Network Resource Identifier (NRI) information where the information indicates that the tracking MSC controls the suitable LAI(s), and the processing unit translating the LAU response into a TAU response which is sent through the first network interface to the UE. A user equipment (UE) includes a processing unit which transmits a tracking area update (TAU) request. The UE includes a network interface in communication with the processing unit which sends the TAU request to a mobility management entity (MME), and receives a TAU response having suitable location area identifiers (LAIs) and TMSI/network resource identifier (NRI). The UE includes a memory in communication with the network interface which stores the suitable LAIs and TMSI/NRI. A method for a mobility management entity (MME) for setting up a call. A method for a user equipment (UE).

A system, method, and arrangement for controlling access to a wireless communication network. When a User Equipment (UE) is denied access to the network through a first access point, the UE stores the Location Area Identity (LAI) utilized at the first access point on a list of forbidden LAIs in the UE. If the LAI stored by the UE is utilized at another access point where the UE is allowed access, the LAI at the other access point is dynamically changed to a second LAI that is not on the UE's list of forbidden LAIs. An access point database stores a table defining which UEs are allowed to utilize each access point. The database also stores a list of rejected LAIs for each UE. A radio network controller accesses the database to determine an allowed LAI, and changes the LAI at the other access points where the UE is allowed access.

An electronic system embodies a security system which provides varying levels of security based on the location of the system. As such, the system includes a location module, such as a geosynchronous positioning system (“GPS”) receiver that permits the system to determine its location relative to a plurality of preset location areas. Such location areas might be programmed to include the user's office, home, predetermined location for a business trip and the like. Based on the location area in which the system is located, the system invokes a security mode associated with that particular location area. Different location areas may have different security modes.

A network communication entity (e.g., an access terminal, access network and/or application server) obtains a location associated with a given access terminal that is attempting to participate in a given communication service, obtains a priority level of the given access terminal, determines a given level of service restriction for the given access terminal's participation in the given communication service based on the obtained location and the obtained priority level and restricts the given access terminal's participation in the given communication service based on the given level of service restriction. In an example, the priority levels can be established such that low-priority access terminals obtain a first level of service restriction within a defined location region, and a second level of service restriction outside of the defined location region, whereas high-priority access terminals obtain the first level of service restriction both inside and outside of the defined location region.

A WLAN distributed/opportunistic scheduling (WDOS) method for acquiring a multi-user diversity gain is disclosed. The WDOS method allows a transmitter (i.e., a transmission user) to observe channel conditions of receivers (i.e., reception users), and commands the transmitter to transmit packets to a specific receiver having a relative good channel condition. The WDOS method uses a modified RTS/CTS exchange method to perform the channel probing. If the transmitter broadcasts the BRTS frame, each receiver transmits a CTS frame after the lapse of its backoff period. According to the reception signal strength distribution, the backoff delay time minimizes the number of CTS collisions irrespective of the number of receivers, reduces an amount of channel probing overheads, and maximizes a multi-user diversity gain. The better the relative channel condition, the lower the backoff delay time.

A TDOA (time difference of arrival) location system, in which mobile wireless devices broadcast wireless signals which are received by two or more transceivers deployed in the vicinity of the mobile wireless device. Each transceiver measures the TOA (time of arrival) of the received broadcasted signal and reports the TOA to a central server. The central server then calculates the mobile device position using multi-lateration of TDOA values. The system uses fiber optic links between the antennas and the transceivers deployed in the location area to provide unique advantages that couldn't be achieved using RF coaxial cables.
