Detailed Description
The following describes the embodiments in further detail with reference to the accompanying drawings.
Example one
The embodiment provides a method for establishing a PDP connection, which is applied to a terminal such as a mobile phone and a router, and as shown in fig. 1, the method includes:
s101, presetting a PDP connection identifier;
here, the PDP connection identifier may be preset when the terminal establishes a connection with the mobile data network. When a mobile network data switch of the terminal is opened, the terminal keeps connection with a PDP (packet data protocol) connection of a mobile data network, and at the moment, whether the terminal has a PDP connection identifier corresponding to the network type of the current SIM card or not can be determined 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 a current first SIM card, and comparing the first network parameter with a stored network parameter list; and when a second network parameter which is the same as the first network parameter exists in the stored network parameter list, taking the PDP connection identifier which is the same as the second network parameter as the PDP connection identifier of the first SIM card. Taking the MCC and MNC of the current SIM card as 460 and 02 respectively as an example, judging whether 460 and 02 exist in a pre-stored network parameter list, and if so, taking the PDP connection identifiers of 460 and 02 in the network parameter list as the PDP connection identifier of the current SIM card.
Specifically, the preset PDP connection identifier may further include: acquiring a first network parameter of a current first SIM card, and comparing the first network parameter with a stored network parameter list; and when the first network parameter of the second network parameter in the stored network parameter list is different from the stored second network parameter, configuring the PDP connection identifier. 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), and other Network parameters for identifying the operator of the SIM card. The second network parameter is the same as the first network parameter in type, except that the first network parameter is the network parameter of the current SIM card, and the second network parameter is the network parameter stored in the terminal.
Preferably, the configuring the PDP connection identifier includes: activating a Packet Data Protocol (PDP) connection of a dialing network (DUN) type; and generating the PDP connection identifier according to the activation result and storing 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, setting the PDP connection identifier as a default type. And attempting to deactivate the DUN-type PDP connection according to the APN information of the current SIM card, setting the PDP connection identifier of the SIM card to be the DUN type when receiving a response of successfully establishing the connection, indicating that the activation of the DUN-type PDP connection fails when not receiving the response of establishing the connection or receiving the response carrying an error code, and setting the PDP connection identifier of the SIM card to be a default type.
Wherein, the step of storing the PDP connection identifier comprises the following steps: acquiring a first network parameter of a current first SIM card of the terminal; and associating the PDP connection identifier with the first network parameter, and storing the PDP connection identifier in a stored network parameter list.
Taking the MCC and MNC of the current SIM card as 460 and 02 respectively as an example, determining whether 460 and 02 exist in a pre-stored network parameter list, when the 460 and 02 do not exist, trying to activate the DUN type PDP connection, when the activation is successful, the PDP connection of the current SIM card is the DUN type, associating and storing the 460 and 02 and the DUN type, and setting the PDP connection identifier of the SIM card with the MCC and MNC of 460 and 02 respectively as the DUN type; when the activation fails, the PDP connection of the current SIM card is of a default type, and 460 and 02 are stored in association with the default type. The PDP connection id of SIM cards with MCC and MNC of 460 and 02, respectively, is set to a default type.
Further, configuring the PDP connection identifier in the embodiment of the present invention may further include: determining whether APN information of a dialing network DUN type exists; activating a DUN-type PDP connection when the APN information of the DUN type exists; when the PDP of the DUN type is activated successfully, setting the PDP connection identifier of the SIM card to be the DUN type; otherwise, setting the PDP connection identifier of the SIM card as a default type; and when the APN information of the DUN type does not exist, setting the PDP connection identifier of the SIM card as a default type.
Similarly, taking the MCC and MNC of the current SIM card as 460 and 02 respectively as an example, acquiring all APN information of the current SIM card, and after acquiring all APN information of the APN, searching whether APN information of DUN type exists; when APN information of the DUN type exists, a PDP connection request of the DUN type is sent to activate PDP connection of the DUN type, when a response of successfully establishing connection is received, a PDP connection identifier of the SIM card is set to be the DUN type, and PDP connection identifiers of SIM cards with MCC and MNC respectively being 460 and 02 are set to be the DUN type; when the response of connection establishment is not received or the response carrying the error code is received, it indicates that activating 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 identifiers of SIM cards with MCC and MNC of 460 and 02, respectively, are set to the default type.
And when the terminal is inserted into the SIM card, acquiring all APN information of the current SIM card. Here, the APN information of the SIM card may be matched by the terminal itself to all APN information of the current operator and stored in the terminal. Of course, in the embodiment of the present invention, the APN information acquisition method is not limited, and may also be acquired by other methods, such as reading an identifier of a corresponding operator, and acquiring all APN information of the operator from a database corresponding to the terminal system according to the identifier of the operator. However, in the embodiment of the present invention, the terminal matching is used as an optimal mode, so that the terminal can be prevented from interacting with the network side and repeatedly performing matching before the hotspot is opened.
The MCC and MNC are 460 and 02 respectively and the corresponding PDP connection identifier is stored in a network parameter list, so that the PDP connection identifier of the network parameter type can be directly acquired when the terminal uses the SIM card with the same network parameter next time.
It should be noted that, in the embodiment of the present invention, the form of the PDP connection identifier is not particularly limited, for example, when the identifier is 0001, the PDP connection is a DUN type PDP connection, and when the identifier is 0000, the PDP connection is a default type PDP connection. And also a DUN type PDP connection when identified as DUN and a default type PDP connection when identified as default.
And S102, when receiving the hotspot opening instruction, establishing PDP connection according to the PDP connection identifier.
And when the user opens the hot spot function and the terminal receives the hot spot opening instruction, the terminal establishes the PDP connection, and at the moment, the establishment of the PDP connection is controlled according to the PDP connection identifier acquired in the S101. Specifically, the type of the PDP connection to be established is determined according to the PDP connection identifier; and controlling the PDP connection corresponding to the SIM card according to the type of the PDP connection.
It should be noted that, in the embodiment of the present invention, two PDP connections may exist at the same time, so that when establishing a connection with a mobile data network, even when a current terminal is performing data services using a PDP connection of a default type, for example, performing data services through a browser, a PDP connection of a DUN type may be activated while maintaining the PDP connection of the current default type. When the PDP connection type is the DUN type, the DUN type PDP connection is established when the hotspot service is carried out, and a new PDP connection can be established while the current default type PDP connection exists. Therefore, when the hotspot sharing service is carried out, two PDP connections exist at the same time.
Therefore, in the method for PDP connection provided in the embodiment of the present invention, determining the PDP connection identifier of the current SIM card according to whether the network parameter of the current SIM card of the terminal is stored in the terminal, specifically, whether the PDP connection identifier of the SIM card of the network parameter type is stored in the terminal includes:
(1) and if the PDP connection identifier corresponding to the current SIM card is not stored in the terminal currently, determining and storing the PDP connection identifier of the current SIM card in a mode of trying to activate the DUN-type PDP connection, and directly using the stored PDP connection identifier as the PDP connection identifier of the current SIM card.
(2) And if the PDP connection identifier corresponding to the current SIM card is currently stored in the terminal, directly taking the stored PDP connection identifier as the PDP connection identifier of the current SIM card.
In practical application, the method for establishing a PDP connection according to the embodiment of the present invention may be used to perform a data sharing service when a terminal is used as a hotspot, and when the terminal performs the data sharing service (network sharing service), whether a DUN type PDP connection is newly established is controlled according to a stored PDP connection identifier, network card information of the DUN type PDP connection is acquired, and the terminal is controlled to establish the DUN type PDP connection according to the network card information. I.e. before the hotspot of the terminal is opened, a suitable configuration has been made. An attempt may be made to determine whether a DUN type PDP was successfully activated based on the configured determination.
The embodiment of the invention and the existing PDP connection method judge whether a dialing PDP (DUN type) needs to be activated again or not, the judging time is different, and proper configuration is already made before a mobile phone hotspot is opened. An attempt is made to determine whether a DUN type PDP has been successfully activated. For the common user often uses one or two SIM cards on average, when the terminal reinserts one SIM card, the reinserted SIM card is the same SIM card inserted before or the SIM card of the same operator, and the method for establishing the PDP connection provided by the embodiment of the invention can avoid repeatedly judging what PDP connection needs to be established. Therefore, for the same type of SIM card, the judgment is already made, and the repeated judgment process is not carried out. It can be intuitively determined whether the sharing is a PDP connection of a default type or a new different PDP connection needs to be reactivated according to the APN information provided by a certain operator.
In the embodiment of the present invention, preferably, the hotspot sharing is a WIFI sharing function, and meanwhile, the hotspot sharing also includes USB sharing, bluetooth sharing, and other hotspot sharing, which is not limited in the embodiment of the present invention.
Example two
In the second embodiment, a specific scenario in which a mobile phone shares network data is taken as an example to further explain the method for establishing a PDP connection provided in the second embodiment of the present invention, as shown in fig. 2, the method includes:
s201, after the terminal is started, all APN information is obtained.
And when the mobile phone is inserted into the SIM card, all APN information of the SIM card can be acquired through the original process of matching all APNs of the current operator by Google in the terminal.
Here, when the SIM card is replaced in the mobile phone, all APN information of the operator corresponding to the current SIM card is re-matched.
S202, connection is established with the mobile data network.
And after the mobile phone is successfully injected into the network, the mobile phone enters a normal use state. When a user opens a data flow switch of the mobile phone, the mobile phone receives a data flow opening command and establishes connection with a mobile network, and at the moment, the terminal has the condition of performing data service through default PDP connection.
And S203, presetting a PDP connection identifier according to the network parameters of the current SIM card.
When the connection with the mobile network is established and the data is successfully activated, the MCC, MNC and other network parameters of the SIM card can be acquired, the PDP connection identifier of the SIM card is preset according to the acquired network parameters, and the preset PDP connection identifier can be stored in a database mode.
When the terminal stores the PDP connection identifier corresponding to the network parameter of the current SIM card, the PDP connection identifier corresponding to the network parameter is directly acquired for storage. And when the terminal does not store the PDP connection identifier corresponding to the network parameter of the current SIM card, configuring the PDP connection identifier of the SIM card in an attempt activation mode.
When the terminal does not store the PDP connection identifier corresponding to the network parameter of the current SIM card, there is a special case that when the user uses the hotspot function for the first time, the terminal does not store any relationship between the network parameter and the PDP connection, and the method for pre-setting the PDP connection including the hotspot function used by the user for the first time is specifically described in embodiment three.
And determining whether the type of the PDP connection of the SIM card is a default type or a DUN type according to a preset PDP connection identifier, directly activating the PDP connection of the default type in a mobile phone system for data transmission without establishing a new PDP connection when the type is the default type, and establishing the new PDP connection when the type is the DUN type to complete the establishment of the PDP connection of the DUN type.
And S204, when receiving the hotspot opening instruction, establishing PDP connection according to the preset PDP connection identifier.
When the user opens the hotspot sharing, the mobile phone receives the hotspot opening instruction to perform 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 PDP connection of the default type of the mobile phone system needs to be activated, and at this time, there is one PDP connection. When the PDP connection type is the DUN type, a DUN type PDP connection is established, and a new PDP connection may be established while the default type PDP connection exists, and at this time, two PDP connections may exist.
EXAMPLE III
In the third embodiment, the method for presetting the PDP connection identifier in S203 in the second embodiment is further described, at this time, when the user has opened the data traffic switch of the mobile phone, the mobile phone receives the data traffic opening command, and establishes a connection with the mobile network; in step 201, the APN information of the current SIM card owned by the operator is automatically matched. And the user can check the matched APN information in the mobile phone setting. As shown in fig. 3, includes:
s301, judging whether the hot spot is opened for the first time; if not, executing S302, if yes, executing S304;
when the mobile phone makes a hot spot for the first time, the SIM card is not inserted into the mobile phone before the mobile phone does not perform hot spot sharing service, so that the PDP connection identifier of the network parameter of any SIM card is not stored;
s302, judging whether the current SIM card and the previously inserted SIM card are the SIM cards of the same network type. If yes, executing S303; if not, executing S304;
and judging whether the current SIM card and the previously inserted SIM card are the SIM cards of the same network type or not according to the network parameters MCC and MNC of the current SIM card and the previously inserted SIM card.
And S303, adopting the PDP connection identifier saved before.
When the network parameters MCC and MNC of the current SIM card and the previously inserted SIM card are identical, that is, when the network parameters of the current SIM card exist in the network parameter list stored in the terminal, it may be determined that the current SIM card and the previously inserted SIM card are the same network type SIM card. The PDP connection identifier associated with the network parameter which is the same as the network parameter of the current SIM card can be obtained and used as the PDP connection identifier of the current SIM card.
S304, trying to activate the DUN type PDP connection according to the APN information of the current SIM card, and obtaining the PDP connection identifier of the SIM card according to the activation result.
Attempting to activate a DUN type PDP connection; when the activation is successful, setting the PDP connection type of the SIM card as a DUN type, and indicating that the hotspot needs to use the DUN type PDP connection for sharing service; and when the SIM card is not successfully activated, setting the PDP connection type of the SIM card as a default type, which indicates that the hotspot needs to use the PDP connection of the default type to share the service.
It should be noted that if the general terminal is not used for the first time, S301 may be omitted, and after S202 is executed, the process proceeds directly to S302.
In the embodiment of the present invention, in step 202, the PDP connection is activated by an attempted method to determine the PDP connection identifier of the SIM card, and the PDP connection identifier is stored after the determination, and when the hotspot is opened, the PDP connection is directly performed according to the preset PDP connection identifier. In practical use, when the terminal does not store the PDP connection identifier corresponding to the network parameter of the current SIM card, and when the PDP connection identifier corresponding to the current SIM card is obtained by attempting activation, the network parameter of the current SIM card and the PDP connection identifier are stored in association, and the network type corresponding to the network parameter and the PDP connection type corresponding to the network type are bound for the next time, the SIM card of the same network type is inserted for PDP connection and direct acquisition.
By the method for connecting the PDP provided by the embodiment of the invention, the type of the PDP connection required to be used by the SIM card is determined by directly acquiring the PDP connection identifier, whether another DUN-type PDP connection needs to be activated again is determined, and meanwhile, the time for re-establishing the PDP connection established by the SIM card is actually carried out before the hot spot is opened by judging the type of the PDP connection established by the SIM card in the embodiment of the invention, so that the hot spot opening efficiency is improved, and the user experience is improved.
