The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 1 is a flowchart of Embodiment 1 of an adaptive processing method for a PDP connection according to the present invention. As shown in FIG. 1 , an adaptive processing method for a PDP connection provided by an embodiment of the present invention may be specifically applied to a PDP connection between a terminal device and a network side in a communication system, where the communication system may specifically be a wideband code division multiple access (Wideband Code). Division Multiple Access (WCDMA), Code Division Multiple Access (CDMA), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), Long Term Evolution (Long Term Evolution) , referred to as LTE). The adaptive processing method of the PDP connection provided in this embodiment may be specifically implemented by using an adaptive device of the PDP connection, and the adaptive processing device of the PDP connection may be integrated in the terminal device or may be independently set, and the terminal device may be For a smartphone or a tablet, the adaptive processing device of the PDP connection can be implemented by means of software and/or hardware. Hereinafter, the adaptive processing method of the PDP connection provided in this embodiment will be described in detail by taking the communication system as WCDMA as an example.

The adaptive processing method of the PDP connection in this embodiment includes:

Step 101: When initiating the Nth PDP activation operation, determine whether the network side supports the N way PDP, where N is an integer greater than or equal to 2;

Step 102: If not, the N-1 way data service is processed by the processing method corresponding to the N-1 way PDP.

The terminal device initiates an Nth PDP activation operation to the network side, and the terminal device can support at least N PDPs, that is, the terminal device can support N different PDPs to coexist at the same time, where N is an integer greater than or equal to 2. For example, at least N-channel PDP smartphones or tablets can be supported. Before the Nth PDP activation operation is initiated, the adaptive processing device of the PDP connection may check that the N-1 PDP has initiated activation. Specifically, the adaptive processing device of the PDP connection may first detect whether a PDP is active. In the process, there is a PDP activated or any of the PDPs being deactivated. If any of the above conditions occurs, the terminal device can be determined to send to the network side. A PDP is activated, and it is determined that the terminal device has initiated the N-1 PDP activation to the network side according to the foregoing method. After determining that the N-1 PDP has been activated, it is determined that the PDP activation request is currently being initiated. Whether the PDP parameter is inconsistent with the N-1 PDP parameter that has been activated by the terminal device. If the PDP parameter is inconsistent, it can be determined that the current request is the Nth PDP. The main parameters of the PDP include the access point and the protocol configuration option. The protocol configuration option includes the authentication information, the user name, the password, and the packet data protocol address. In this embodiment, the PDP may be determined to be different according to the access point, or may be different according to any one of the protocol configuration options. To determine that the PDP is different, it is also possible to determine that the PDP is different according to the difference of all the parameters of the main parameters of the PDP, and is not limited herein.

For determining whether the network side supports the N-channel PDP, the network device may support the N-channel PDP according to whether the network supports the N-channel PDP, for example, the network side recorded by the terminal device supports the N-channel PDP, and may The network side initiates the Nth PDP activation operation. If the network side recorded by the terminal device does not support the N way PDP, the N-1 way data service may be processed by using the processing method corresponding to the N-1 way PDP; The terminal device does not have a record of whether the network side supports the N-channel PDP, and may initiate the N-th PDP activation operation to the network side to determine whether the network side supports the N-th PDP, and if the network side responds to accept the Nth The path PDP determines that the network side supports the N way PDP. If the response result of the network side is to reject the Nth PDP, it is determined that the network side does not support the N way PDP.

If the network side does not support the N-channel PDP, the N-1 way data service is processed by the N-1 way PDP, and the service type of the N-channel PDP or the size of the data quantity may be prioritized. If the lowest priority is the data service that is initiating the Nth PDP activation, the PDP connection of the current N-1 data service is maintained. If the lowest priority is the data service that is initiating the Nth PDP activation, the PDP connection of the lowest priority data service is released, and the Nth PDP is activated. It is also possible to first release the PDP of the last one of the N-1 PDPs, and then connect the Nth PDP.

The embodiment provides an adaptive processing method for a PDP connection. The method for determining whether the network side supports the N-channel PDP, and then performing the N-way or N-1-channel PDP corresponding method according to the determination result processes the N-way or the N- - 1 channel data service, when the network side does not support the N-channel PDP, the terminal device can process the N-1 data service by using the processing method corresponding to the N-1 PDP, so that the N-1 channel PDP network environment can be used. The terminal device is used normally for the data service of the N-channel PDP version, thereby solving the stability of the service quality of the data service. FIG. 2 is a flowchart of Embodiment 2 of an adaptive processing method for a PDP connection according to the present invention. As shown in FIG. 2, in step 101, determining whether the network side supports the N-channel PDP may include:

Step 1011: Send an Nth active PDP context request message to the network side, and receive an activated PDP context response message fed back by the network side;

Step 1012: If the PDP context response message is activated, the network side supports the N-way PDP. If the PDP context response message is activated as the reject response message, it is determined that the network side does not support the N-way PDP.

Further, in step 1012, if the PDP context response message is activated as the reject response message, it is determined that the network side does not support the N-channel PDP, and may further include:

Resending the Nth active PDP context request message to the network side;

Make sure that the network side does not support N-channel PDP, including:

If the activated PDP context reject response message is received again, it is determined that the network side does not support the N-way PDP.

Specifically, the terminal device sends an Nth active PDP context request message to the network side, and after receiving the active PDP context response message fed back by the network side as a reject response message, the terminal device may resend the Nth active PDP context request message to the network side. The number of times the Nth active PDP context request message is sent to the network side may be one time or multiple times. After receiving the active PDP context reject response message fed back by the network side, it may be determined that the network side does not support the N way PDP.

In this embodiment, if the PDP context response message is activated as the reject response message, it is determined that the network side does not support the N-channel PDP.

The error code used to indicate the retry in the reject response message is filtered.

After the terminal device sends the Nth active PDP context request message to the network side, and receives the active PDP context response message fed back by the network side as the reject response message, the adaptive processing device of the PDP connection may respond to the activated PDP context response message fed back by the network side. The error code carried in the network is used to determine whether the network side supports the N-channel PDP. The error code fed back by the network side refers to the incorrect parameter of the terminal device, for example, an authentication error or a packet data protocol address error, etc. The error code indicates that the information of the retry of the terminal device is filtered, and the Nth active PDP context request message is not sent to the network side, but the network side does not support the N way PDP, and then the N-1 PDP is used. The corresponding processing method processes the N-1 way data service.

This embodiment provides an adaptive processing method for a PDP connection, by using a reject response message. The error code carried in the network is used to determine whether the network side supports the N-channel PDP, and the N-th active PDP context request message may not be sent to the network side again, thereby determining whether the network side supports the N-channel PDP, thereby reducing the network side. Load.

In this embodiment, after determining whether the network side supports the N-channel PDP in step 101, the method further includes:

Store the feature information of the N-channel PDP on the network side locally.

Specifically, after determining whether the network side supports the N-channel PDP, the PDP-connected adaptive processing device stores the characteristic information of the N-channel PDP or the non-supporting PDP on the network side locally, where the local connection may be a PDP connection. The storage medium that is adapted to the processing device or the terminal device is not limited herein.

Correspondingly, in step 101, before determining whether the network side supports the N-channel PDP, the method further includes:

Determine whether the local storage network side supports the feature information of the N-channel PDP.

If yes, determine whether the network side supports the N-channel PDP according to the locally stored characteristic information.

If no, the operation of determining whether the network side supports the N-way PDP is performed.

Specifically, when the terminal device initiates the Nth PDP activation operation to the network side, the terminal device first determines whether the network side supports the characteristic information of the N-channel PDP, and the characteristic information may specifically include: the network side supports the N-channel PDP. Or, the network side does not support the N-channel PDP. If the terminal device stores the characteristic information of the N-channel PDP, the network device can determine whether the network side supports the N-channel PDP according to the characteristic information stored locally, and according to the characteristic information. For the specific content, different processing methods are used, that is, the N-1 way data service is processed by the N-1 way PDP, or the Nth line data service is connected. If the terminal device does not store the feature information of whether the network side supports the N-channel PDP, perform the foregoing operation of determining whether the network side supports the N-channel PDP.

Further, before determining whether the network side supports the N-channel PDP according to the locally stored characteristic information, the method further includes:

After the network is successfully attached or is in the idle state or the service state is triggered, it is detected whether the currently accessed network side supports the N-channel PDP, and the result of the detection is stored as the characteristic information.

The terminal device may first establish a connection with the network side at the link control layer after the initial startup and after the network is successfully attached or in an idle state, but there is no transmission of service traffic, and the adaptive processing device of the PDP connection detects the current access. Whether the network side supports the N-channel PDP, and stores the result of the detection as the characteristic information, so that the N-th data service initiates a service connection. The adaptive processing method of the PDP connection provided in this embodiment, by storing whether the currently accessed network side supports the characteristic information of the N-channel PDP, can implement the corresponding processing manner according to whether the network side supports the N-channel PDP according to the network side. The data service is processed, so that the data service of the terminal device can be used normally, thereby solving the stability of the service quality of the data service.

Further, when the network registration status changes, the characteristic information stored locally is deleted. Specifically, when the terminal device establishes a connection with the network side, the terminal device records the network registration information, where the information may include a country code and an operator code. When the network registration status changes, that is, the country code or the carrier code. When any or all of the items change, the terminal device can delete all the characteristic information of the network side stored locally. The terminal device may also delete the characteristic information of the network side, record the new network side characteristic information, and establish a multi-network side characteristic information list, which is used when the terminal device switches on different network sides.

In this embodiment, in step 102, the N-1 way data service is processed by using the processing method corresponding to the N-1 way PDP, which may specifically include:

Determine the priority between the N-way data services;

Release the PDP connection of the lowest priority data service.

Specifically, when determining that the network side supports the N-1 PDP, determining the priority mode between the N data services may be sorted according to the service type or the data volume of the N data service, and is not limited herein. The way of sorting is not limited here. If the lowest priority is the data service that is initiating the Nth PDP activation, the PDP connection of the current N-1 data service is maintained, and if the lowest priority is the data service that is initiating the Nth PDP activation, the release is performed. The PDP connection of the lowest priority one-way data service performs the N-th PDP activation.
