CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This application is a continuation of PCT/CN2012/078355, filed on Jul. 9, 2012, which claims priority to Chinese Patent Application No. 201110196034.9, filed on Jul. 13, 2011, all of which is hereby incorporated by reference in its entirety. 
     
    
     TECHNICAL FIELD 
       [0002]    Embodiments of the present invention relate to the technical field of communications, and in particular, to a method and an apparatus for automatic dialing access point. 
       BACKGROUND 
       [0003]    An access point, that is, an APN (Access Point Name), is a parameter which must be configured when a terminal device accesses a network, and determines an access manner in which the terminal device accesses the network. At present, a terminal may perform a data service in two manners, namely, a static APN and a dynamic APN. 
         [0004]    When a data service is performed in a manner of static APN dialing, an operator customizes multiple available APNs and store APN information in a terminal file, terminal device software provides a manual selection interface, and when a terminal user manually selects a certain APN, a corresponding GGSN (Gateway GPRS Support Node, gateway GPRS support node) may be obtained to connect to a data network, so as to execute the data service. If the data network is connected successfully, process the data service, if the data network is not connected successfully, manually select another APN to connect to the data network, and if the data network is still not connected successfully, end the operation. 
         [0005]    When a data service is performed in a manner of dynamic APN dialing, multiple available APNs correspond to MCCs (Mobile Country Code, mobile country code) or MNCs (Mobile Network Code, mobile network code) of IMSI (International Mobile Subscriber Identification Number, international mobile subscriber identification number) number segments in SIM (Subscriber Identity Module, subscriber identity module) cards, that is to say, SIM cards of different number segments correspond to different APN information. The APN information is stored in a terminal file, and when a terminal user inserts a SIM card, a program in a terminal queries an MCC or MNC message in the SIM card, and automatically obtains, by adapting, an APN message corresponding to the MCC or MNC in the SIM card, so as to obtain a corresponding GGSN to connect to the data network, thereby executing the data service. 
         [0006]    With the expansion of operators&#39; business, each operator manages multiple sub-brands, and the sub-brands share a same MCC or MNC; however, the sub-brands may have different service types, and different services also have different APN information; when dialing is performed by using the prior art, available APN information may not be effectively acquired according to the MCC or MNC. 
       SUMMARY 
       [0007]    Embodiments of the present invention provide a method and an apparatus for automatic dialing access point, which may implement automatic dialing, and improve correctness of acquired APN information. 
         [0008]    In order to achieve the foregoing objective, the embodiments of the present invention adopt the following technical solutions: 
         [0009]    A method for automatic dialing access point includes: 
         [0010]    performing automatic dialing in the following three manners in any sequence, until the dialing succeeds or the dialing still fails after the three manners are all used:

     DESCRIPTION OF EMBODIMENTS 
       [0027]    To make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the embodiments and the accompanying drawings. Herein, the exemplary embodiments of the present invention and the description are merely intended to explain the present invention, but are not intended to limit the present invention. 
       Embodiment 1 
       [0028]    An embodiment of the present invention provides a method for automatic dialing access point, and as shown in  FIG. 1 , the method includes: performing automatic dialing in three manners in any sequence as described in the following three steps, until the dialing succeeds or the dialing still fails after the three manners are all used: 
         [0029]    Step  101 : Detect APN information corresponding to information in a SIM card, and perform automatic dialing according to the detected APN information corresponding to the information in the SIM card. 
         [0030]    Here, the information in the SIM card includes: an MCC or MNC, a GID (Group Identification, group identification) value, and a network standard with which the SIM card is registered. 
         [0031]    The APN information includes: APN information corresponding to the MCC or MNC, APN information corresponding to the GID, and APN information corresponding to the network standard, where, the APN information is stored in the SIM card according to a combination sequence of the information in the SIM card, or stored in client software. 
         [0032]    Step  102 : Detect APN information corresponding to preset board software, and perform automatic dialing according to the detected APN information corresponding to the preset board software. 
         [0033]    The preset board software is software directly performing interaction with hardware. The APN information corresponding to the preset board software mainly depends on APN information corresponding to a parameter written in the preset board software. An operator pre-configures APN information in board software of a product, and client software acquires the APN information by sending an AT command, and performs automatic dialing. 
         [0034]    Step  103 : Perform automatic dialing according to APN information preset in client software. 
         [0035]    In the method for automatic dialing access point provided in the embodiment of the present invention, automatic dialing is performed in three manners: detecting APN information corresponding to information in a SIM card, and performing automatic dialing according to the detected APN information corresponding to the information in the SIM card; detecting APN information corresponding to preset board software, and performing automatic dialing according to the detected APN information corresponding to the preset board software; and performing automatic dialing according to APN information preset in client software. 
         [0036]    Compared with the prior art, a problem that when sub-brands managed by an operator share the same MCC or MNC but do not share APN information due to different service types, available APN information may not be effectively acquired according to the MCC or MNC can be solved. 
         [0037]    An embodiment of the present invention provides an apparatus for automatic dialing access point, and as shown in  FIG. 2 , the apparatus includes: a first dialing unit  201 , a second dialing unit  202 , a third dialing unit  203 , and a control unit  204 . 
         [0038]    The first dialing unit  201  is configured to detect APN information corresponding to information in a SIM card, and perform automatic dialing according to the detected APN information corresponding to the information in the SIM card. 
         [0039]    The second dialing unit  202  is configured to detect APN information corresponding to preset board software, and perform automatic dialing according to the detected APN information corresponding to the preset board software. 
         [0040]    The third dialing unit  203  is configured to perform automatic dialing according to APN information preset in client software. 
         [0041]    The control unit  204  is configured to trigger any one of the first dialing unit  201 , the second dialing unit  202 , and the third dialing unit  203 , trigger any one of the other two units when the unit fails in dialing, and when the dialing unit also fails in dialing, trigger the rest dialing unit. 
         [0042]    Preferably, the control unit may trigger the three dialing units according to a sequence being the first dialing unit  201 , the second dialing unit  202 , and the third dialing unit  203 . Optionally, if the three dialing units all fail in dialing, the control unit further sends a prompt of dialing failure. 
         [0043]    Compared with the prior art, the apparatus for automatic dialing access point provided in the embodiment of the present invention can solve a problem that when sub-brands managed by an operator share a same MCC or MNC but do not share APN information due to different service types, available APN information may not be effectively acquired according to the MCC or MNC. 
       Embodiment 2 
       [0044]    An embodiment of the present invention provides a method for automatic dialing access point, and as shown in  FIG. 3 , the method includes: 
         [0045]    In the solution provided in the embodiment of the present invention, automatic dialing may be performed in the following three manners: performing automatic dialing according to APN information corresponding to information in a SIM card, performing automatic dialing according to APN information corresponding to preset board software, and performing automatic dialing according to APN information preset in client software; the three automatic dialing manners may be randomly ordered and randomly combined. In the present invention, a detailed description is given in a sequence that automatic dialing is performed first according to APN information corresponding to information in a SIM card, automatic dialing is performed according to APN information corresponding to preset board software, and then automatic dialing is performed according to APN information preset in client software. 
         [0046]    Step  301 : Detect access point APN information corresponding to information in a subscriber identity module SIM card, and perform automatic dialing according to the detected APN information corresponding to the information in the SIM card. 
         [0047]    The information in the SIM card includes: a mobile country code MCC/mobile network code MNC, a group identification GID value, and a network standard with which the SIM card is registered. 
         [0048]    An APN (Access Point Name, access point) is a parameter which must be configured when a terminal device accesses a network, and determines an access manner in which the terminal device accesses the network. 
         [0049]    Specifically, as shown in  FIG. 4 , an implementation manner of step  301  is as follows: 
         [0050]    It should be noted that, the APN information corresponding to the information in the SIM card is preset according to a combination of APN information corresponding to an MCC/MNC, APN information corresponding to a group identification GID value, and APN information corresponding to a network standard with which the SIM card is registered; further, a combination manner of the APN information corresponding to the information in the SIM card may be APN information corresponding to an MCC/MNC, APN information corresponding to a network standard with which the SIM card is registered, and APN information corresponding to a group identification GID value; or 
         [0051]    APN information corresponding to a group identification GID value, APN information corresponding to an MCC/MNC, and APN information corresponding to a network standard with which the SIM card is registered; or 
         [0052]    APN information corresponding to a group identification GID value, APN information corresponding to a network standard with which the SIM card is registered, and APN information corresponding to an MCC/MNC; or 
         [0053]    APN information corresponding to a network standard with which the SIM card is registered, APN information corresponding to an MCC/MNC, and APN information corresponding to a group identification GID value; or 
         [0054]    APN information corresponding to a network standard with which the SIM card is registered, APN information corresponding to a group identification GID value, and APN information corresponding to an MCC/MNC; and 
         [0055]    the APN information is preset according to any combination sequence of APN information as described in the foregoing, and automatic dialing may be performed according to the APN information corresponding to specific information. The APN information is stored in a file of the SIM card, or stored in client software, and then an AT (Attention) command is sent by the client software to query corresponding APN information. 
         [0056]    Preferably, the APN information corresponding to the MCC/MNC and the APN information corresponding to the information in the GID have a strongest association, the network standard varies correspondingly according to a network registration situation. Therefore, in an exemplary solution of the embodiment of the present invention, dialing according to the APN information corresponding to the information in the SIM card is described in detail according to such a combination of APN information corresponding to an MCC/MNC, APN information corresponding to a group identification GID value, and APN information corresponding to a network standard with which the SIM card is registered. 
         [0057]    Step  401 : Acquire an MCC or MNC in the SIM card. 
         [0058]    MCC (Mobile Country Code) is a mobile country code, MCC resources are uniformly allocated and managed by the International Telecommunication Union (ITU), the MCC uniquely identifies a country to which a mobile user belongs, and has a total of 3 digits, and the MCC of China is 460. 
         [0059]    MNC (Mobile Network Code) is a mobile network code, the MNC has a total of 2 digits, a GSM system of China Mobile uses 00 and 02, a GSM system of China Unicom uses 01, a CDMA system of China Telecom uses 03, and a TD system of China Mobile uses 07. 
         [0060]    Specifically, the client software queries the MCC or MNC by sending an AT (Attention) command. 
         [0061]    Step  402 : Detect, according to the acquired MCC or MNC, whether APN information corresponding to the MCC or MNC exists. 
         [0062]    Specifically, according to the acquired MCC or MNC in the SIM card, it may acquire, in the file of the SIM card or the client software, whether APN information corresponding to the MCC or MNC exists. 
         [0063]    Step  403 : If APN information corresponding to the MCC or MNC exists, perform automatic dialing according to the detected APN information corresponding to the MCC or MNC in the SIM card. 
         [0064]    Step  404 : If no APN information corresponding to the MCC or MNC exists, acquire a GID value in the SIM card. 
         [0065]    If no APN information corresponding to the MCC or MNC exists, in this case, dialing needs to be performed in another manner. 
         [0066]    GID (Group Identification, group identification) refers to an identity of a user of a shared resource system, is a common graphical user interface having strong adaptability and a friendly user interface, which is used for geometrical simulation, data input, model transformation, grid and a visualization result, and is applicable to all types of numerical simulation packets. SIM cards of some GIDs specially represent users having specific functions, for example, a type of users with a GID being A may be free in short messages, a type of users with a GID being A may be free in multimedia messages, and in this way, an operator may set APN information according to the GID. 
         [0067]    Specifically, the client software acquires a GID value in the SIM card file by sending an AT command. 
         [0068]    Step  405 : Detect, according to the acquired GID value, whether APN information corresponding to the GID value exists. 
         [0069]    According to the acquired GID value, query the file of the SIM card or the client software to determine whether APN information corresponding to the GID value exists. 
         [0070]    Step  406 : If APN information corresponding to the GID value exists, perform automatic dialing according to the detected APN information corresponding to the GID value in the SIM card. 
         [0071]    Step  407 : If no APN information corresponding to the GID value exists, acquire a network standard with which the SIM card is registered. 
         [0072]    The network standard is a type of network, and frequency bands commonly used by mobile phones in China mainly include a CDMA1X, 800 MHz frequency band occupied by CDMA mobile phones, a 900/1800/1900 MHz frequency band occupied by GSM mobile phones; a 900/1800 MHz frequency band occupied by GSM1X dual-mode; and a 900/1800/1900/2100 MHz frequency band occupied by 3G. 
         [0073]    Step  408 : Detect, according to the acquired network standard, whether APN information corresponding to the network standard exists. 
         [0074]    Step  409 : If APN information corresponding to the network standard exists, perform automatic dialing according to the detected APN information corresponding to the network standard with which the SIM card is registered. 
         [0075]    Step  410 : If no APN information corresponding to the network standard exists, dialing fails. 
         [0076]    If no APN information corresponding to the network standard exists, a manner of performing automatic dialing according to the APN information corresponding to the information in the SIM card fails, and automatic dialing needs to be performed in another manner. 
         [0077]    Continuously referring to step  302  in  FIG. 3 , determine whether the dialing succeeds. 
         [0078]    Step  303 : If the dialing succeeds, start a browser. 
         [0079]    Step  304 : When the dialing fails, detect APN information corresponding to preset board software, and perform automatic dialing according to the detected APN information corresponding to the preset board software. 
         [0080]    A board generally refers to a circuit board, and specifically may be a PCB board. The preset board software is software directly performing interaction with hardware, and the APN information corresponding to the preset board software mainly depends on APN information corresponding to a parameter written in the preset board software. A product provider pre-configures APN information of a user in preset board software, and client software acquires the APN information by sending an AT command, and performs dialing according to the detected APN information corresponding to the preset board software. 
         [0081]    Step  305 : Determine whether the dialing succeeds. 
         [0082]    If the dialing succeeds, turn to step  303  to start the browser and perform data processing. 
         [0083]    Step  306 : When the previous dialing fails, perform automatic dialing according to APN information preset in the client software. 
         [0084]    It should be noted that, after being installed, a client stores preset APN information to a PC, and the client software reads the APN information from a configuration file on the PC, and performs automatic dialing. 
         [0085]    Step  307 : Determine whether the dialing succeeds. 
         [0086]    If the dialing succeeds, turn to step  303  to start the browser and perform data processing. 
         [0087]    Step  308 : When the dialing fails, start a diagnosis function. 
         [0088]    It should be noted that, when the automatic dialing fails, manual dialing may be performed according to the APN information set by the user, the client software provides an interface for creating APN, and the APN information is acquired from the operator. 
         [0089]    If all dialing manners fail, the client software diagnoses information such as signal strength, whether hardware is damaged, and whether the SIM card is damaged, so as to illustrate that the dialing fails. 
         [0090]    It should be noted that, in the solution provided in the embodiment of the present invention, a sequence of the three manners of performing automatic dialing is not strictly fixed, and the three manners of automatic dialing, namely, performing automatic dialing according to APN information corresponding to information in a SIM card, performing automatic dialing according to APN information corresponding to preset board software, and performing automatic dialing according to APN information preset in client software, may be randomly ordered and randomly combined. 
         [0091]    In the method for automatic dialing access point provided in the embodiment of the present invention, automatic dialing is performed according to the provided three manners, and compared with the prior art, the method can solve a problem that when sub-brands managed by an operator share the same MCC or MNC but do not share APN information due to different service types, available APN information may not be effectively acquired according to the MCC or MNC. 
         [0092]    An embodiment of the present invention provides an apparatus for automatic dialing access point, and as shown in  FIG. 5 , the apparatus includes: a first dialing unit  501 , a determining unit  502 , a login unit  503 , a second dialing unit  504 , a third dialing unit  505 , a diagnosis starting unit  506 , and a control unit  507 .

         [0098]    A board generally refers to a circuit board, and specifically may be a PCB board. The preset board software is software directly performing interaction with hardware, and the APN information corresponding to the preset board software mainly depends on APN information corresponding to a parameter written in the preset board software. A product provider pre-configures APN information of a user in preset board software, and client software acquires the APN information by sending an AT command, and performs dialing according to the detected APN information corresponding to the preset board software. 
         [0099]    The third dialing unit  505  is configured to perform automatic dialing according to APN information preset in client software. 
         [0100]    The control unit  507  is further configured to: if the three dialing units all fail in dialing, further send a prompt of dialing failure. The diagnosis unit  506  is configured to start a diagnosis function when the control unit  507  prompts dialing failure. 
         [0101]    It should be noted that, when the automatic dialing fails, manual dialing may be performed according to the APN information set by the user, the client software provides an interface for creating APN, and the APN information is acquired from the operator. 
         [0102]    If all dialing manners fail, the client software diagnoses information such as signal strength, whether hardware is damaged, and whether the SIM card is damaged, so as to illustrate that the dialing fails. 
         [0103]    It should be noted that, in the apparatus for performing automatic dialing in the solution provided in the embodiment of the present invention, a sequence of execution of the first dialing unit, the second dialing unit and the third dialing unit in the apparatus is not strictly fixed, and the sequence of performing automatic dialing of the three units may be randomly ordered and randomly combined. Preferably, the control unit may trigger the three dialing units according to a sequence being the first dialing unit, the second dialing unit, and the third dialing unit. 
         [0104]    Specifically, as shown in  FIG. 6 , the first dialing unit  501  includes: an acquiring module  601 , a detecting module  602 , a dialing module  603 , and a control module  604 . 
         [0105]    The acquiring module  601  is configured to acquire an MCC or MNC in a SIM card. 
         [0106]    MCC (Mobile Country Code) is a mobile country code, MCC resources are uniformly allocated and managed by the International Telecommunication Union (ITU), the MCC uniquely identifies a country to which a mobile user belongs, and has a total of 3 digits, and the MCC of China is 460.

         [0108]    The detecting module  602  is configured to detect, according to the acquired MCC or MNC, whether APN information corresponding to the MCC or MNC exists. 
         [0109]    After acquiring the MCC or MNC, query a file in the SIM card to determine whether APN information corresponding to the MCC or MNC exists.

SIM cards of some GIDs specially represent users having specific functions, for example, a type of users with a GID being A may be free in short messages, a type of users with a GID being A may be free in multimedia messages, and in this way, an operator may set APN information according to the GID. 
         [0113]    The detecting module  602  is further configured to detect, according to the acquired GID value, whether APN information corresponding to the GID value exists. 
         [0114]    The dialing module  603  is further configured to: if APN information corresponding to the GID value exists, perform automatic dialing according to the detected APN information corresponding to the GID value in the SIM card. 
         [0115]    The acquiring module  601  is further configured to acquire a network standard with which the SIM card is registered. 
         [0116]    The network standard is a type of network, and frequency bands commonly used by mobile phones in China mainly include a CDMA1X, 800 MHz frequency band occupied by CDMA mobile phones, a 900/1800/1900 MHz frequency band occupied by GSM mobile phones; a 900/1800 MHz frequency band occupied by GSM1X dual-mode; and a 900/1800/1900/2100 MHz frequency band occupied by 3G. 
         [0117]    The detecting module  602  is further configured to detect, according to the acquired network standard, whether APN information corresponding to the network standard exists. 
         [0118]    The dialing module  603  is further configured to: if APN information corresponding to the network standard exists, perform automatic dialing according to the detected APN information corresponding to the network standard with which the SIM card is registered. 
         [0119]    The control module  604  is configured to control the acquiring module  601  to acquire any one of three types of information including the MCC or MNC in the SIM card, the GID in the SIM card, and the network standard with which the SIM card is registered, when the dialing module  603  fails in dialing, trigger the acquiring module  601  to acquire any one of the other two types of information, and when the dialing module  603  fails in dialing again, trigger the acquiring module  601  to acquire the rest one type of information. 
         [0120]    It should be noted that, the APN information is preset according to such as a combination of APN information corresponding to an MCC/MNC, APN information corresponding to a group identification GID value, and APN information corresponding to a network standard with which the SIM card is registered, where, the sequence of the APN information corresponding to an MCC/MNC, the APN information corresponding to a group identification GID value, and the APN information corresponding to a network standard with which the SIM card is registered is not strictly fixed, and they can be randomly combined. The APN information is stored in the SIM card. 
         [0121]    Compared with the prior art, the apparatus for automatic dialing access point provided in the embodiment of the present invention can solve a problem that when sub-brands managed by an operator share a same MCC or MNC but do not share APN information due to different service types, available APN information may not be effectively acquired according to the MCC or MNC. 
         [0122]    Through the foregoing description of the implementation manners, a person skilled in the art can clearly understand that the present invention can be implemented in a manner of software plus a necessary universal hardware platform, and certainly, may also be implemented by hardware; however, in most cases, the former is a preferred implementation manner. Based on such understanding, the technical solution of the present invention or the part that makes contributions to the prior art can be substantially embodied in a form of a software product.
