Description:
TECHNICAL FIELD 
       [0001]    The disclosure relates to a key verification technology for an Ad Hoc network, in particular to a method, device and system for verifying Mobile Equipment (ME). 
       BACKGROUND 
       [0002]    The Ad Hoc network is a multi-hop, centerless and self-organized wireless network, and is also called a multi-hop network, an infrastructure-less network or a self-organized network. The Ad Hoc network is free of fixed infrastructures, and each node is mobile, and can dynamically keep in touch with other nodes in any manner. In the Ad Hoc network, due to a limitation of a wireless coverage of ME, when two pieces of ME cannot directly communicate, packet forwarding by virtue of other nodes is allowed. 
         [0003]    At present, there are mainly two modes for connection establishment between two pieces of ME in the Ad Hoc network: one is to directly establish a connection without setting a key for verification in both pieces of ME, or to establish the connection through an Ad Hoc hotspot in a packet forwarding way; and the other is to set a fixed key and a verification mode in the Ad Hoc hotspot by one piece of ME, verify the fixed key in the Ad Hoc hotspot by the other ME and establish the connection between the two pieces of ME by virtue of the Ad Hoc hotspot as a router after a connection with the Ad Hoc hotspot is established. 
         [0004]    However, in the two modes for the connection establishment, when the ME establishes the connection with the Ad Hoc hotspot, the key is not set, or only the fixed key is set, so that when there are users of different telecommunication operating companies in the same region, if there is only the Ad Hoc hotspot provided by one telecommunication operating company in this region, the Ad Hoc hotspot simultaneously provides service for ME of multiple telecommunication operating companies due to the fact that the key is not set for the Ad Hoc hotspot or only the fixed key which can be extremely easily acquired by all the users is set, and the ME of the other telecommunication operating companies pre-empt service resources to cause influence on the quality of service of the Ad Hoc hotspot over the ME used by its own customers and further probably reduce an Average Revenue Per User (ARPU) of the telecommunication operating company to which the Ad Hoc hotspot belongs due to the fact that the Ad Hoc hotspot cannot provide different service for the ME of different telecommunication operating companies. 
         [0005]    It can be seen that according to a conventional method for the connection establishment between the ME and the Ad Hoc hotspot, the key is not set or only the fixed key is set, which leads to the incapability of the Ad Hoc hotspot in providing different service for the ME of different telecommunication operating companies and results in the pre-empting of the ME of the other telecommunication operating companies over service resources of the telecommunication operating company to which the Ad Hoc hotspot belongs, thereby affecting the quality of service of the Ad Hoc hotspot over its own users and further probably reducing the ARPU of the telecommunication operating company to which the Ad Hoc hotspot belongs. 
       SUMMARY 
       [0006]    To this end, the disclosure provides methods, devices and a system for verifying ME, which enable an Ad Hoc hotspot to provide different service for ME of different telecommunication operating companies, thereby ensuring the quality of service of the Ad Hoc hotspot provided by the telecommunication operating company for its own customers using the ME and further ensuring an ARPU of the telecommunication operating company.

     DETAILED DESCRIPTION 
       [0049]    A basic thought of the disclosure is: an Ad Hoc hotspot, after determining that ME transmitting equipment information is legal equipment, transmits corresponding ME information generated according to the equipment information to operating company database equipment, and receives verification key information returned by the operating company database equipment; and after receiving a key verification request from the ME, the Ad Hoc hotspot verifies the ME by utilizing the corresponding verification key information, notifies the ME that the ME passes the verification if the ME passes the verification, and establishes a connection with the ME. 
         [0050]    The disclosure is further described below with reference to the drawings and specific embodiments in detail. 
         [0051]    The disclosure provides a method for verifying ME, and as shown in  FIG. 1 , the method includes the following steps. 
         [0052]    Step  101 : an Ad Hoc hotspot receives equipment information from ME. 
         [0053]    The equipment information here may include contents such as an International Mobile Subscriber Identification Number (IMSI), an International Mobile Equipment Identity (IMEI), a manufacturer code and an operating company logo; wherein the IMSI is acquired by the ME from a Subscriber Identity Module (SIM) card installed in the ME, and a method for acquiring the IMSI exists in the existing technology, and will not be repeated here. 
         [0054]    Step  102 : the Ad Hoc hotspot judges whether the corresponding ME is legal equipment or not according to the received equipment information; Step  103  is then executed if the corresponding ME is legal equipment, otherwise the ME is notified that the ME cannot access the Ad Hoc hotspot, and the processing flow is ended. 
         [0055]    Here, judging whether the corresponding ME is legal equipment or not includes that: the Ad Hoc hotspot extracts the operating company logo and/or the manufacturer code from the equipment information as critical information, checks whether the critical information is the same as an operating company logo and/or a manufacturer code, which are/is stored by the Ad Hoc hotspot, or not, determines that the corresponding ME is legal equipment if the critical information is the same as the operating company logo and/or the manufacturer code, which are/is stored by the Ad Hoc hotspot, and if the critical information is different from the operating company logo and/or the manufacturer code, which are/is stored by the Ad Hoc hotspot, determines that the corresponding ME is illegal equipment, 
         [0056]    the contents required to be included in the critical information may also be set by a telecommunication operating company according to actual conditions, for example, one or more of the IMSI, the manufacturer code, the IMEI, the operating company logo information and a mobile phone number in the equipment information may be extracted as the critical information. 
         [0057]    Step  103 : the Ad Hoc hotspot transmits the ME information of the ME to the operating company database equipment, and receives verification key information returned by the operating company database equipment. 
         [0058]    Here, the ME information is information consisting of the IMSI, the manufacturer code and the mobile phone number, which are extracted from the equipment information; and the operating company database equipment is network equipment storing an operating company database. 
         [0059]    The verification key information includes a verification key and the IMSI, and may also include one or more of a traffic control strategy, an ME downloading traffic rate, a downloading type and one or more of service types; wherein the verification key is preset according to actual conditions by the telecommunication operating company, and can be modified according to actual needs. 
         [0060]    After the Ad Hoc hotspot transmits the ME information to the operating company database equipment, Step  103  further may include that: the operating company database equipment generates key information and the verification key information according to the ME information, transmits the key information to the ME and transmits the verification key information to the Ad Hoc hotspot; 
         [0061]    the key information may be random data generated by the operating company database equipment, and may also be a preset key; the key is preset according to actual conditions by the telecommunication operating company, and can be modified according to actual needs; and the key information is transmitted to the corresponding ME according to the IMSI or the mobile phone number in the ME information received from the Ad Hoc hotspot. 
         [0062]    Step  104 : the Ad Hoc hotspot judges whether a key verification request is received from the ME or not, Step  105  is then executed if the key verification request is received, otherwise Step  104  is repeated. 
         [0063]    Here, the key verification request includes the key and the equipment information. 
         [0064]    Step  105 : the Ad Hoc hotspot utilizes the verification key information to verify the ME transmitting the key verification request, notifies the ME that the ME passes the verification if the ME passes the verification, establishes a connection with the corresponding ME and ends the processing flow, otherwise transmits a notice indicating that the ME does not pass the verification to the ME. 
         [0065]    Here, the verification is implemented in a way that the Ad Hoc hotspot extracts the key and the equipment information from the key verification request, searches for the corresponding verification key information according to the IMSI in the equipment information, compares the found verification key information with the key in the key verification request, determines that the ME passes the verification if the found verification key information is the same as the key in the key verification request, otherwise determines that the ME does not pass the verification. 
         [0066]    establishing a connection between the Ad Hoc hotspot and the corresponding ME includes that: the Ad Hoc hotspot extracts the equipment information from the key verification request, stores the equipment information and establishes the connection with the corresponding ME according to the equipment information; and a method for establishing the connection exists in the existing technology, and will not be repeated here. 
         [0067]    In addition, before Step  101  is executed, the ME is required to start establishing a connection with another piece of ME according to an operation of a user, and transmits the equipment information to the corresponding Ad Hoc hotspot according to the existing technology; and 
         [0068]    after Step  103  is finished, the ME acquires the key from the received key information, and transmits the key verification request to the Ad Hoc hotspot by utilizing the key, and then Step  104  is executed. 
         [0069]    The equipment information may be added by the ME into a Route Request (RREQ) message of a link layer and then transmitted to the Ad Hoc hotspot, or may also be added by the ME into a Transmission Control Protocol (TCP) message of a transport layer and then transmitted to the Ad Hoc hotspot, or may also be added by the ME into an application related message of an application layer and then transmitted to the Ad Hoc hotspot; the adoption of a transmission mode may be set by the telecommunication operating company according to actual conditions; the RREQ message, the TCP message and the application related message are messages specified in the existing technology, and will not be repeated here. 
         [0070]    Transmitting the key verification request to the Ad Hoc hotspot by utilizing the key is as follows: when the key information is random data, the ME generates a key according to an encryption algorithm by utilizing the random data in the key information, compiles the key and the equipment information of the ME into the key verification request; when the key information is a preset key, the ME directly extracts the key, and compiles the key and the equipment information of the ME into the key verification request; wherein the encryption algorithm may be preset according to actual conditions.
