Aspects of the disclosure provide a computer-implemented method and system for the assignment of roadside assistance service providers such as tow trucks to distressed vehicles/drivers requiring roadside assistance. The methods and systems may include a roadside assistance service provider system with a collection module, an assignment module, and a feedback module. The collection module collects roadside assistance service provider information and historical statistics from real-world information and stores the information in a database that may then be analyzed using particular rules and formulas. The assignment module assigns particular roadside assistance service providers to particular distressed vehicles/drivers based on one or more characteristics. The feedback module may provide near real-time cues to the tow truck driver's mobile device, such as alerting when the amount of time spent on a task exceeds a predefined threshold, flagging high priority tasks/assignments, providing a step-by-step checklist for the repair.

A wireless device uses position-indicating data to determine its location in relation to multi-layered wireless networks that the device may see concurrently. If location information is available, the device employs a user-defined priority table to select the order of user-contracted available networks. If location information is unavailable, the device employs a technology learning table to automatically adapt CAI protocol options (e.g., GSM, cdma2000, IS-136, IEEE 802.11x, etc.) to search for an available network. Information is gathered and stored in databases within the device to allow automatic adaptation to multiple wireless networks. The device provides unique access to each wireless network with which a user has contracted, without the intervention of any “anchor” network. This allows the device to obtain network service no matter what network it is traveling through and allows the user to traverse multiple wireless networks with seamless access to multiple applications and services provided by those networks.

In a system and method for handoff using a hybrid network, a wireless local area network (WLAN) terminal determines its own position information through communication with a code division multiple access (CDMA) base station and a global positioning system (GPS) satellite, and a cell mapping server obtains information about a WLAN cell where the WLAN terminal is currently located from the WLAN terminal position information, determines information about a cell to which the terminal is expected to be handed off from the current position of the WLAN terminal, and provides the cell information to the WLAN terminal. This allows handoff to be performed without scanning a destination access point, thereby significantly reducing WLAN handoff time.

A mobile communication system with a packet switching function which enables sharing of radio resources among mobile stations, wherein a mobile station which has generated a request for communication quality assurance periodically sends a packet for requesting preferential use of a radio channel in order to prevent timeout of the state transition timer, timeout of which would cancel radio channel assignment to the mobile station and bring it into a dormant state if a certain period elapses without transmission or reception of a signal, so that it can remain in the active state and hold the radio channel continuously. In addition, when the mobile station requesting communication quality assurance moves from one cell to another or requests radio channel assignment, the base station controller controls the radio base station so that the mobile station can be assigned a radio channel by sending a priority request packet.

A method of establishing a relationship between access nodes in a wireless communications network is provided. An access node is registered with the network. Information about each access node registered with the network is then stored at a control node. A list is then compiled at the control node, which includes each access node registered with the network and the list indicates which access node is a neighbour of another access node. This neighbour list is sent from the control node to each access node in the network. When an access node detects other access nodes, this is reported to the control node, which updates the neighbour list to the access nodes.

Allocation of a wireless communications system channel resource is managed by utilizing traffic segment allocation. This is realized by partitioning the channel resource into an assignment channel and a traffic channel in a fixed manner. The assignment channel includes assignment segments and the traffic channel includes traffic segments. The traffic segment is the basic traffic channel resource unit used to transport traffic data and has a prescribed finite time interval and bandwidth. Each traffic segment is associated with a so-called assignment segment in a prescribed manner. One or more traffic segments may be associated with a particular assignment segment. A base station broadcasts via an assignment segment which wireless terminal is to use a particular traffic segment. This is realized by transmitting a simply identifier for the particular wireless terminal assigned to the particular traffic segment in the assignment segment. Then, each active wireless terminal monitors all of the received assignment segments to detect any traffic channel assignments. Once a wireless terminal detects its identifier in an assignment segment, it proceeds to receive/transmit the traffic data in the traffic segment associated with the assignment segment including the detected identifier.
