Embodiment 1

This embodiment provides a method for establishing a PDP connection, which is applied to a terminal such as a mobile phone or a router. As shown in FIG. 1 , the method includes:

S101, preset PDP connection identifier;

Here, the PDP connection identifier may be preset when the terminal establishes a connection with the mobile data network. When the mobile network data switch of the terminal is turned on, the terminal maintains a connection with the PDP connection of the mobile data network. Then, at this time, it may be determined whether the terminal has a PDP connection identifier corresponding to the network type of the current SIM card to determine the type of the PDP connection established when the hotspot is opened.

Specifically, the preset PDP connection identifier may include: acquiring a first network parameter of the current first SIM card, comparing the first network parameter with the stored network parameter list; and when the stored network parameter list exists and When the first network parameter with the same network parameter is the same, the PDP connection identifier with the same second network parameter is used as the PDP connection identifier of the first SIM card. Taking the current MCC and MNC of the SIM card as 460 and 02 respectively, it is determined whether the pre-stored network parameter list determines whether there is 460 or 02, and when present, the PDP connection identifier of 460 and 02 in the network parameter list is used as the current SIM. The PDP connection ID of the card.

Specifically, the preset PDP connection identifier may further include: acquiring a first network parameter of the current first SIM card, comparing the first network parameter with the stored network parameter list; and when the stored network parameter list is in the second network When the first network parameter of the parameter is different from the stored second network parameter, the PDP connection identifier is configured. Here, the first network parameter is a network parameter of the current SIM card, and the network parameter may include a Mobile Country Code (MCC), a Mobile Network Code (MNC), or the like for identifying the operator of the SIM card. Network parameters. The second network parameter is the same as the network parameter of the first network parameter, except that the first network parameter is a network parameter of the current SIM card, and the second network parameter is a network parameter stored in the terminal.

Preferably, the configuring the PDP connection identifier comprises: activating a packet data protocol PDP connection of a dial-up network DUN type; generating the PDP connection identifier according to the activation result and saving the PDP connection identifier. Specifically, when the DUN type PDP connection can be activated, the PDP connection identifier is set to the DUN type; otherwise, the PDP connection identifier is set to the default type. According to the APN information of the current SIM card, an attempt is made to deactivate the DUN type PDP connection. When receiving the response of successfully establishing the connection, the PDP connection identifier of the SIM card is set to the DUN type, and when the connection establishment response is not received or received When the response with the error code is carried, it indicates that the activation of the DUN type PDP connection fails, and the PDP connection identifier of the SIM card is set to the default type.

The saving the PDP connection identifier includes: acquiring a first network parameter of the current first SIM card of the terminal; associating the PDP connection identifier with the first network parameter, and saving the information in the stored network parameter list.

Taking the MCC and MNC of the current SIM card as 460 and 02 respectively as an example, it is determined whether there is 460 or 02 in the pre-stored network parameter list, and when it does not exist, try to activate the DUN type PDP connection, when the activation is successful. The PDP connection of the current SIM card is of the DUN type, and the 460, 02 and DUN types are associated and saved. The PDP connection identifiers of the SIM cards of the MCC and the MNC respectively 460 and 02 are set to the DUN type; when the activation fails, the current SIM card is used. The PDP connection is the default type, and 460, 02 are associated with the default type. The PDP connection identifiers of the SIM cards of the 460 and 02, respectively, of the MCC and the MNC are set to the default type.

In an embodiment of the present invention, the configuring the PDP connection identifier in the embodiment of the present invention may further include: determining whether there is an APN information of the dialing network DUN type; and when there is a DUN type APN information, activating the DUN type PDP connection. When the PDP connection of the DUN type is activated, the PDP connection identifier of the SIM card is set to the DUN type; otherwise, the PDP connection identifier of the SIM card is set to the default type; when there is no AUN information of the DUN type; , setting the PDP connection identifier of the SIM card to a default type.

For example, the current SIM card's MCC and MNC are respectively 460 and 02, and all the APN information of the current SIM card is obtained. After all the APN information of the APN is obtained, the APN information of the DUN type is found. The APN information is sent to the DUN type PDP connection request to activate the DUN type PDP connection. When receiving the response to successfully establish the connection, the PDP connection identifier of the SIM card is set to the DUN type, and the MCC and the MNC are respectively 460. The PDP connection identifier of the SIM card of 02 is set to the DUN type; when the response of the connection establishment is not received or the response with the error code is received, it indicates that the activation of the DUN type PDP connection fails, or when there is no DUN type APN information. The PDP connection identifier of the SIM card is set to the default type, and the PDP connection label of the SIM card of the 460 and 02 is respectively MCC and MNC. The setting is set to the default type.

After the terminal inserts the SIM card, all APN information of the current SIM card is obtained. Here, the APN information of the SIM card can be matched by the terminal itself to all APN information of the current operator, and is saved in the terminal. Certainly, in the embodiment of the present invention, the manner of obtaining the APN information is not limited, and the operation may be obtained from the database corresponding to the terminal system by reading the identifier of the corresponding operator and according to the identifier of the operator. All other methods such as APN information are obtained. However, in the embodiment of the present invention, the terminal itself is matched in a preferred manner, so that each time the terminal interacts with the network side before the hotspot is opened, and the matching is repeated.

The MCC and the MNC are respectively stored in the network parameter list for the 460, 02 and the corresponding PDP connection identifiers, so that when the terminal uses the SIM card of the same network parameter next time, the PDP connection identifier of the network parameter type can be directly obtained.

It should be noted that, in the embodiment of the present invention, the form of the PDP connection identifier is not specifically limited. For example, when the identifier is 0001, it is a DDP type PDP connection, and when the identifier is 0000, it is a default type PDP connection. . It can also be a DDP type PDP connection when it is identified as DUN. When the identifier is default, it is the default type of PDP connection.

S102. When receiving a hotspot open command, establish a PDP connection according to the PDP connection identifier.

When the user turns on the hotspot function and the terminal receives the hotspot open command, the terminal establishes a PDP connection. At this time, the establishment of the PDP connection is controlled according to the PDP connection identifier acquired in S101. Specifically, the type of the PDP connection to be established is determined according to the PDP connection identifier; and the PDP connection corresponding to the SIM card is controlled according to the type of the PDP connection.

It should be noted that, in the embodiment of the present invention, two PDP connections can exist at the same time, so when establishing a connection with the mobile data network, even if the current terminal is using the default type of PDP connection for data services, such as through a browser. In the case of data services, a DDP type PDP connection can also be activated while maintaining the current default type of PDP connection. When PDP connection class When the type is DUN, a DDP type PDP connection is established when the hotspot service is performed, and a new PDP connection can be established while the current default type PDP connection exists. Therefore, when the hotspot sharing service is performed, there are two PDP connections at the same time.

Therefore, in the method for connecting a PDP provided by the embodiment of the present invention, whether the network parameter of the current SIM card of the terminal is stored in the terminal, and specifically, whether the PDP connection of the SIM card of the network parameter type is already stored in the terminal The identification to determine the PDP connection identifier of the current SIM card includes:

(1) If the PDP connection identifier corresponding to the current SIM card is not currently stored in the terminal, the PDP connection identifier of the current SIM card is determined and saved by attempting to activate the PDP connection of the DUN type, and the saved PDP connection identifier is directly used as the current SIM. The PDP connection ID of the card.

(2) If the PDP connection identifier corresponding to the current SIM card is currently stored in the terminal, the saved PDP connection identifier is directly used as the PDP connection identifier of the current SIM card.

In a practical application, the method for establishing a PDP connection in the embodiment of the present invention may be used to perform a data sharing service when the terminal is a hotspot. When the terminal performs a data sharing service (network sharing service), it controls according to the saved PDP connection identifier. Whether to establish a DDP type PDP connection, and obtain the DUN type PDP connection network card information, and control the terminal to establish the DUN type PDP connection according to the network card information. That is to say, before the hotspot of the terminal is opened, the appropriate configuration has been made. In the judgment mode of the configuration, an attempt can be made to determine whether a DUN type PDP can be successfully activated.

The method for connecting to the existing PDP in the embodiment of the present invention determines whether it is necessary to re-activate another dial-up PDP (DUN type), and the time for making the judgment is different. Before the mobile phone hotspot is opened, the appropriate configuration has been made. The attempted method is used to determine whether a DUN type PDP can be successfully activated. For the average user, one or two SIM cards are often used on average. When the terminal reinserts a SIM card, the same SIM card that was previously inserted or the SIM card of the same carrier is reinserted, and implemented by the present invention. Example The method of establishing a PDP connection avoids repeating the judgment of what kind of PDP connection needs to be established. Therefore, for the same type of SIM card, if a judgment has been made, the repeated judgment process is not performed. According to the APN information provided by a certain operator, it can be intuitively judged whether the sharing uses the default type of PDP connection or whether a new different PDP connection needs to be reactivated.

In the embodiment of the present invention, the hotspot is shared as a WIFI sharing function, and the hotspot sharing such as the USB sharing and the Bluetooth sharing is also included in the embodiment of the present invention.

Embodiment 2

In the second embodiment, the method for establishing a PDP connection provided by the embodiment of the present invention is further described by using a mobile phone to perform the method for sharing the network data. As shown in FIG. 2, the method includes:

S201: After the terminal is started, obtain all APN information.

The mobile phone is inserted into the SIM card, and all APN information of the SIM card can be obtained through Google's native process of matching all current APNs of the current operator.

Here, when the SIM card is replaced in the mobile phone, all APN information corresponding to the operator of the current SIM card is re-matched.

S202, establishing a connection with a mobile data network.

When the mobile phone successfully fills the network, it enters the normal use state. When the user turns on the data flow switch of the mobile phone, the mobile phone receives the data traffic open command and establishes a connection with the mobile network. At this time, the terminal has a data service through the default PDP connection.

S203. Pre-set a PDP connection identifier according to network parameters of the current SIM card.

After establishing a connection with the mobile network, the data is successfully activated, and the network parameters such as the MCC and the MNC of the SIM card are obtained, and the PDP connection identifier of the SIM card is preset according to the acquired network parameters, and the preset PDP connection identifier can be in the database manner. Store.

When the PDP connection identifier corresponding to the network parameter of the current SIM card is stored in the terminal, the PDP connection identifier corresponding to the network parameter is directly obtained for storage. When there is no storage in the terminal When the PDP connection identifier corresponding to the network parameter of the previous SIM card is used, the PDP connection identifier of the SIM card is configured by attempting to activate.

There is a special case when the PDP connection identifier corresponding to the network parameter of the current SIM card is not stored in the terminal, that is, when the user uses the hotspot function for the first time, no network parameters associated with the PDP connection are stored in the terminal. The method for the preset PDP connection including the first use of the hotspot function by the user is specifically described in the third embodiment.

According to the preset PDP connection identifier, it is determined whether the type of the PDP connection of the SIM card is a default type or a DUN type. When the default type is used, it is not necessary to establish a new PDP connection, and directly activate the default type of PDP connection in the mobile phone system. Data transmission, when it is DUN type, it is necessary to establish a new PDP connection and complete the establishment of a DUN type PDP connection.

S204. When receiving the hotspot open command, establish a PDP connection according to the preset PDP connection identifier.

When the user opens the hotspot sharing, the mobile phone receives the hotspot open command to perform the hotspot sharing service, and establishes a PDP connection according to the PDP connection identifier preset in S203. When the PDP connection type is the default type, only the default type of PDP connection of the mobile phone system needs to be activated. At this time, there is a PDP connection. When the PDP connection type is DUN type, a DDP type PDP connection is established, and a new PDP connection can be established at the same time as the default type of PDP connection exists. At this time, there may be two PDP connections.

Embodiment 3

In the third embodiment, the method for presetting the PDP connection identifier of the S203 in the second embodiment is further described. At this time, when the user has turned on the data flow switch of the mobile phone, the mobile phone receives the data traffic open command and establishes with the mobile network. And; in step 201, the APN information of the operator of the current SIM card is automatically matched. Among them, the user can view the matched APN information in the phone settings. As shown in Figure 3, it includes:

S301. Determine whether the hot spot is opened for the first time; if not, execute S302, if yes, execute S304;

When the mobile phone hits the hot spot for the first time, the mobile phone has not inserted the SIM card before, and the hot spot sharing service is not performed. Therefore, the PDP connection identifier of the network parameter of the SIM card is not saved;

S302. Determine whether the current SIM card and the previously inserted SIM card are SIM cards of the same network type. If yes, execute S303; if not, execute S304;

The network parameters MCC and MNC of the SIM card and the previously inserted SIM card are used to determine whether the current SIM card and the previously inserted SIM card are SIM cards of the same network type.

S303. Use the previously saved PDP connection identifier.

When the current SIM card is consistent with the network parameters MCC and MNC of the previously inserted SIM card, that is, when the network parameter of the current SIM card exists in the network parameter list stored in the terminal, the current SIM card and the previously inserted SIM may be determined. The card is a SIM card of the same network type. The PDP connection identifier associated with the network parameter of the current SIM card may be obtained as the PDP connection identifier of the current SIM card.

S304. Try to activate a DDP type PDP connection according to the APN information of the current SIM card, and obtain the SIM card PDP connection identifier according to the activation result.

An attempt is made to activate a PDP connection of the DUN type. When the activation is successful, the PDP connection type of the SIM card is set to the DUN type, indicating that the hotspot needs to use the DUN type PDP connection for the sharing service; when the activation is not successful, the SIM card is The PDP connection type is set to the default type, indicating that the hotspot needs to use the default type of PDP connection for sharing services.

It should be noted that if the general terminal is not used for the first time, S301 may be ignored, and after S202 is executed, the process proceeds directly to S302.

In the embodiment of the present invention, the PDP connection is activated by the attempted method in step 202 to determine the PDP connection identifier of the SIM card, and is determined to be saved. When the hotspot is opened, the PDP connection is directly performed according to the preset PDP connection identifier. In actual use, the current SIM is not saved in the terminal. The PDP connection identifier corresponding to the network parameter of the card, when the PDP connection identifier corresponding to the current SIM card is obtained by attempting to activate, the network parameter of the current SIM card is associated with the PDP connection identifier, and the network parameter is corresponding. The network type is bound to the PDP connection type corresponding to the network type, so that the SIM card of the same network type can be inserted next time to obtain the PDP connection directly.

The PDP connection method provided by the foregoing embodiment of the present invention determines the type of the PDP connection that the SIM card needs to use by directly obtaining the PDP connection identifier, and determines whether it is necessary to re-activate another DUN type PDP connection. In the embodiment of the present invention, it is determined whether the type of the PDP connection established by the SIM card needs to be re-established before the hotspot is opened, thereby improving the efficiency of the hotspot opening and improving the user experience.
