Abstract

A method and mobile device for location determination using sequential pattern recognition are disclosed. The method comprises determining a specific sequence of identifiers of a plurality of base transceiver stations that control cells through which a mobile device has passed when travelling along a path. The specific sequence of identifiers of a plurality of base transceiver stations are compared with a look-up table stored in a database. The look-up table comprises all possible sequence of identifiers of base transceiver stations and a location for each of the sequence of identifiers of base transceiver stations. The location of the path is determined from the comparison.

the mobile device of the customer, and the customer; and

when the requiring vehicle message is received by the server, the server decodes the information related to the mobile device of the customer and the customer, to obtain information related to the mobile device of the customer and its location.

44. A method as claimed in claim 39, wherein if the server receives acceptance messages from more than one of the available vehicles within the predetermined range of the mobile device of the customer, the server sends the customer message to the mobile device of the first-received acceptance and deletes the successful vehicle and/or the mobile device of the successful vehicle from a database of available vehicles;

the customer message comprises the information relating to the mobile device of the customer and the customer;

the mobile device of the successful vehicle uses the information relating to the mobile device of the customer and the customer to contact the mobile device of the customer to obtain relevant details of the customer;

the mobile device of the customer is sent a notification providing details of the successful vehicle and its mobile device; and

the server sends rejection notifications to the mobile devices of those available vehicles that were not successful.
