In order to make the objects, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The data connection method provided by the application can be applied to the application environment shown in fig. 1. Wherein the terminal device 102 communicates with the operator server 104 over a network. The terminal device 102 sends a data connection request carrying a session to be identified and a service continuous mode SSC mode of the terminal device 102 and a data network name DNN to be identified to the operator server 104, receives and identifies a data connection result which is sent by the operator server 104 based on the data connection request and comprises SSC mode illegal and/or DNN illegal, correspondingly generates a new data connection request carrying an adjusted SSC mode and/or adjusted DNN according to the data connection result, and sends the new data connection request to the operator server 104. The terminal device 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the operator server 104 may be implemented by an independent server or a server cluster formed by multiple servers.
In an embodiment, as shown in fig. 2, a data connection method is provided, which is described by taking the method as an example applied to the terminal device in fig. 1, and includes the following steps:
s210, sending a data connection request to an operator server.
The data connection request carries a session to be identified, a service continuity mode SSC and a data network name DNN to be identified of the terminal. A Session and Service Continuity Mode (SSC Mode) is one of attributes of a Protocol Data Unit (PDU) Session in a wireless communication system. In this embodiment, the process of sending the data connection request is a process of establishing a PDU session. Data Network Name (DNN) is used to characterize the type of Data Network, for example, DNN in china mobile is CMNET, DNN in china telecom is UNINET, and DNN in china telecom is CTNET.
In addition, the SSC Mode has three types, the SSC Mode 1 allocates a user plane session anchor point for the PDU session, and the user plane session anchor point is kept unchanged in the survival period of the whole PDU session, and in the Mode, the requirement of the PDU session on the continuity is high; SSC Mode 2 means that a user plane session anchor point is allocated for a PDU session, but the user plane session anchor point can only be kept in a certain service area, when a User (UE) removes from the service area of the user plane session anchor point, the UE needs to select a new user plane session anchor point, and under the Mode, the PDU session has low requirement on continuity but high requirement on service quality; SSC Mode 3 means that a user plane session anchor point to a Data Network (DN) has been allocated to a PDU session, and before the connection between the UE and the user plane session anchor point is terminated, a new PDU session to the DN is established for the UE, and a new user plane session anchor point is selected for the new PDU session, and the UE can transfer a Data stream to the new PDU session and delete the connection of the previous PDU session. The SSC Mode indicated by different operator servers is different.
Optionally, the terminal device provides the selected SSC Mode (SSC Mode 1 to SSC Mode 3) and the selected DNN (CMNET, UNINET, CTNET) for the user on the interface, and receives a selection instruction of the user for the selected SSC Mode and the selected DNN, wherein the selection instruction comprises the selected SSC Mode and the selected DNN, and the terminal device carries the selected SSC Mode and the selected DNN to send a data connection request to the operator server.
And S220, receiving and identifying a data connection result sent by the operator server based on the data connection request.
Wherein the data connection result comprises SSC mode illegal and/or DNN illegal.
Optionally, the operator server receives the data connection request sent by the terminal device, determines whether the SSC Mode to be identified and the DNN to be identified carried in the data connection request are legal, determines a data connection result according to the determination result, and feeds the data connection result back to the terminal device. For example, the operator server respectively judges whether the SSC Mode to be identified and the DNN to be identified carried in the received data connection request are the pre-stored SSC Mode and DNN, if both are the pre-stored SSC Mode and DNN, the operator server determines that the SSC Mode to be identified and the DNN to be identified carried in the data connection request sent by the terminal device are legal, determines that the data connection result is successful, and simultaneously sends the data connection result to the terminal device. If the SSC Mode to be identified is not the preset SSC Mode, the operator server determines that the data connection fails, and sends the invalid SSC Mode as a data connection result to the terminal equipment. Similarly, if the DNN to be identified is not the preset DNN, the operator server determines that the data connection fails and sends the DNN illegally serving as a data connection result to the terminal equipment.
Optionally, the terminal device receives a result identifier, which is sent by the operator server based on the data connection request and is used for ensuring the data connection result, and determines the data connection result corresponding to the result identifier according to a preset correspondence between the result identifier and the data connection result. For example, the correspondence between the pre-stored result identifier and the data connection result includes: result flag #68 indicates that the data connection result is not SSC Mode supported, i.e., SSC Mode is illegal, and result flag #91 indicates that the data connection result is not DNN recognized, i.e., DNN is illegal. And the operator server correspondingly returns result identification #68 and/or #91 to the terminal equipment under the condition that the SSC Mode is determined to be illegal and/or the DNN is determined to be illegal. The terminal equipment receives result identification #68 and/or #91 sent by the operator server based on the data connection request and used for representing that the data connection result is SSC Mode illegal and/or DNN illegal. The data connection result is determined by adopting the identification result identification, the result identification is simple and easy to identify, the identification process of the data connection result is simplified, and the identification efficiency of the data connection result is improved.
And S230, correspondingly generating a new data connection request according to the data connection result and sending the new data connection request to the operator server.
Wherein the new data connection request correspondingly carries the adjusted SSC mode and/or the adjusted DNN.
Optionally, when the data connection result is that the SSC Mode is illegal, correspondingly adjusting the SSC Mode to be identified carried in the data connection request to obtain an adjusted SSC Mode, and the terminal device generates a new data connection request by using the adjusted SSC Mode together with the previous DNN to be identified, and sends the new data connection request to the operator server.
Optionally, when the data connection result is that the DNN is illegal, the adjusted DNN is obtained corresponding to the DNN to be identified carried in the data connection adjustment request, and the terminal device generates a new data connection request by using the adjusted DNN together with the previous SSC Mode to be identified, and sends the new data connection request to the operator server.
Optionally, in the case that the result of the data connection is that the SSC Mode is illegal and the DNN is illegal, correspondingly adjusting the SSC Mode to be identified and the DNN to be identified carried in the data connection request to obtain an adjusted SSC Mode and an adjusted DNN, and the terminal device generates a new data connection request by using the adjusted SSC Mode and the adjusted DNN and sends the new data connection request to the operator server.
Optionally, the process of adjusting the SSC Mode to be identified and/or the DNN to be identified may be that the SSC Mode to be identified and/or the DNN to be identified are correspondingly adjusted to be the SSC Mode and/or the DNN pre-stored on the terminal device, and the pre-stored SSC Mode and/or the pre-stored DNN are valid SSC Mode and/or DNN stored locally after the terminal device is legally registered in the operator server. The SSC Mode/DNN identification method can be used for identifying the SSC Mode/DNN to be identified, and can be used for correspondingly adjusting the SSC Mode/DNN to be identified into the valid SSC Mode/DNN to be identified. The procedure for adjusting the SSC Mode to be identified and/or the DNN to be identified is not particularly limited herein.
In this embodiment, the terminal device sends a data connection request carrying the SSC Mode to be identified and the DNN to be identified to the operator server, receives and identifies a data connection result sent by the operator server based on the data connection request, and correspondingly generates a new data connection request carrying the adjusted SSC Mode and/or the adjusted DNN under the condition that the data connection result includes that the SSC Mode is illegal and/or the DNN is illegal, and sends the new data connection request to the operator server to initiate the new data connection request to perform data connection again, so that the problem that the data connection request is rejected and the problem cannot be recovered to access the internet due to an input error of the SSC Mode and/or the DNN is avoided.
In one embodiment, in a case that the result of the data connection is that the SSC mode is illegal, as shown in fig. 3, the S230 includes:
s310, if the SSC mode is illegal, the SSC mode to be identified is adjusted to be a legal SSC mode.
Optionally, the valid SSC mode is a local SSC mode pre-stored in the terminal device, and the local SSC mode is a valid SSC mode obtained after the terminal device is legally registered with the operator server. Specifically, the terminal equipment sends a registration request carrying the SSC mode to be registered to an operator server, after the registration request passes the verification of the operator server, the operator server feeds back the successful registration to the terminal equipment, the terminal equipment stores the SSC mode to be registered as a legal SSC mode in the local, and the SSC mode to be identified is adjusted to be the legal SSC mode prestored in the local of the terminal equipment under the condition that the data connection result sent by the operator server is received to be that the SSC mode is illegal.
In an optional embodiment, the data connection result further carries a legal SSC mode, that is, after the registration request passes the verification of the operator server, the operator server takes the SSC mode to be registered in the registration request as the legal SSC mode and stores the legal SSC mode, and when an invalid data connection result of the SSC mode is sent to the terminal device, the stored legal SSC mode is also carried in the data connection result and sent to the terminal device. And the terminal equipment analyzes the data connection result to obtain a legal SSC mode.
And S320, generating a new data connection request based on the legal SSC mode and the DNN to be identified, and sending the new data connection request to an operator server.
Specifically, the terminal device generates a new data connection request together with the obtained legal SSC mode and the previous DNN to be identified, and sends the new data connection request to the operator server. For example, the SSC mode to be identified is SSC mode 1, the DNN to be identified is CMNET, the data connection result sent by the operator server to the terminal device is that the SSC mode is illegal, the legal SSC mode stored locally in the terminal device is SSC mode 2, and the terminal device generates a new data connection request together with the SSC mode 2 and the CMNET and sends the new data connection request to the operator server.
In this embodiment, when the data connection result is that the SSC mode is illegal, the terminal device adjusts the SSC mode to be identified to a legal SSC mode, generates a new data connection request based on the legal SSC mode and the DNN to be identified, and sends the new data connection request to the operator server. The regulated legal SSC mode is carried to send a new data connection request to the operator server, so that the permanent connection refusal caused by the fact that the terminal equipment repeatedly sends the data connection request by adopting the illegal SSC mode is avoided, the problem that the terminal equipment cannot surf the internet due to the illegal SSC mode is recovered, and the internet surfing is successful.
In an embodiment, in the case that the SSC mode is a limited number, as shown in fig. 4, the S230 includes:
s410, under the condition that the SSC mode is illegal, sequentially and transversely selecting a candidate SSC mode from a preset SSC mode library to serve as the adjusted SSC mode.
The SSC mode base is preset in the terminal equipment and comprises three candidate SSC modes including SSC mode 1, SSC mode 2 and SSC mode 3.
Optionally, when the data connection result sent by the operator server is received by the terminal device and is an SSC mode, one candidate SSC mode is selected as the adjusted SSC mode in three candidate SSC modes in a preset SSC mode library in a sequentially traversing manner according to the sequence of the numbers from small to large.
And S420, generating a new data connection request based on the adjusted SSC mode and the DNN to be identified, and sending the new data connection request to the operator server until the data connection result represents that the SSC mode is legal.
Specifically, the terminal device generates a new data connection request together with the adjusted SSC mode and the previous DNN to be identified, sends the new data connection request to the operator server, and receives a data connection result returned by the operator server until the data connection result indicates that the SSC mode is legal. For example, the SSC mode to be identified is SSC mode 1, the DNN to be identified is CMNET, the data connection result sent by the operator server to the terminal device is that the SSC mode is illegal, the terminal device traverses three candidate SSC modes in the SSC mode library from small to large according to the number of the SSC modes, that is, the terminal device uses SSC mode 2 as the adjusted SSC mode, generates a new data connection request together with the CMNET and sends the new data connection request to the operator server, receives the data connection result returned by the operator server, and if the data connection result returned by the operator server is still the SSC mode illegal, the terminal device uses SSC mode 3 as the adjusted SSC mode, generates a new data connection request together with the CMNET and sends the new data connection request to the operator server, and receives the data connection result returned by the operator server until the data connection result represents that the mode is legal.
In this embodiment, because the number of SSC modes is limited, when receiving that the result of data connection is an SSC mode, the terminal device sequentially traverses and selects one candidate SSC mode from a preset SSC mode library as an adjusted SSC mode, and further generates a new data connection request based on the adjusted SSC mode and the DNN to be identified and sends the new data connection request to the operator server until the result of data connection represents that the SSC mode is legal, so that the adjustment of the illegal SSC mode to the legal SSC mode is realized, and the problem that the terminal device cannot surf the internet due to illegal SSC mode repeatedly sending data connection requests is avoided, so that the network access is successfully achieved.
In one embodiment, in a case that the data connection result is DNN illegal, as shown in fig. 5, the S230 includes:
and S510, under the condition that the DNN is illegal, adjusting the DNN to be identified to be legal DNN.
Optionally, the valid DNN is a local DNN pre-stored in the terminal device, where the local DNN is a valid DNN obtained after the terminal device is legally registered with the operator server. Specifically, the terminal device sends a registration request carrying DNN to be registered to an operator server, after the registration request passes the verification of the operator server, the operator server feeds back successful registration to the terminal device, the terminal device stores the DNN to be registered locally as legal DNN, and the DNN to be identified is adjusted to be the legal DNN prestored locally in the terminal device when the received DNN connection result sent by the operator server is that the DNN is illegal.
In an alternative embodiment, the terminal device may adjust the DNN to be identified to an empty DNN.
And S520, generating a new data connection request based on the legal DNN and the SSC mode to be identified, and sending the new data connection request to an operator server.
Specifically, the terminal device generates a new data connection request together with the obtained legal DNN and the previous SSC mode to be identified, and sends the new data connection request to the operator server. For example, the SSC mode to be identified is SSC mode 1, the DNN to be identified is CMNET, the data connection result sent by the operator server to the terminal device is that DNN is illegal, the terminal device adjusts CMNET to be null DNN, and generates a new data connection request together with SSC mode 1 and null DNN and sends the new data connection request to the operator server.
In this embodiment, when the data connection result is that the DNN is illegal, the terminal device adjusts the DNN to be identified to a legal DNN, and generates a new data connection request based on the legal DNN and the SSC mode to be identified, and sends the new data connection request to the operator server. The regulated legal DNN is carried to initiate a new data connection request to the operator server in the mode, so that the phenomenon that the terminal equipment adopts the illegal DNN to repeatedly send the data connection request to cause permanent connection refusal is avoided, the problem that the terminal equipment cannot surf the internet due to the illegal DNN is recovered, and the internet surfing is successful.
In an embodiment, in the case that the DNN is a limited number, as shown in fig. 6, the step S230 includes:
s610, under the condition that the DNN is illegal, one candidate DNN is sequentially selected from a preset DNN library in a traversing mode to serve as the adjusted DNN.
The terminal equipment is preset with a DNN library, wherein the DNN library comprises three candidate DNNs including CMNET, UNINET and CTNET.
Optionally, when the data connection result received by the terminal device and sent by the operator server is that the DNN is illegal, sequentially selecting one candidate DNN as the adjusted DNN from three candidate DNNs in a preset DNN library in a traversing manner according to the sequence of mobile-unicom-telecommunications.
S620, generating a new data connection request based on the adjusted DNN and the SSC mode to be identified and sending the new data connection request to an operator server until the data connection result represents that the DNN is legal.
Specifically, the terminal device generates a new data connection request together with the adjusted DNN and the previous SSC mode to be identified, sends the new data connection request to the operator server, and receives a data connection result returned by the operator server until the data connection result indicates that the DNN is legal. For example, the SSC mode to be identified is SSC mode 1, the DNN to be identified is CMNET, the data connection result sent by the operator server to the terminal device is DNN illegal, the terminal device traverses three candidate DNNs in the DNN library according to the mobile-unicom-telecommunications sequence, that is, the terminal device uses UNINET as the adjusted DNN, generates a new data connection request together with SSC mode 1 and sends the new data connection request to the operator server, and receives the data connection result returned by the operator server, if the data connection result returned by the operator server is still DNN illegal, the terminal device uses CTNET as the adjusted DNN, generates a new data connection request together with SSC mode 1 and sends the new data connection request to the operator server, and receives the data connection result returned by the operator server until the data connection result represents that the DNN is legal.
In this embodiment, as the DNNs are limited, when the terminal device receives a data connection result that the DNN is illegal, the terminal device sequentially traverses and selects one candidate DNN from a preset DNN library as an adjusted DNN, and then generates a new data connection request based on the adjusted DNN and the SSC mode to be identified and sends the new data connection request to the operator server until the data connection result represents that the DNN is legal, so as to adjust the illegal DNN to the legal DNN, thereby avoiding permanent connection refusal caused by the terminal device repeatedly sending the data connection request by adopting the illegal DNN, and recovering the problem that the terminal device cannot surf the internet due to the illegal DNN, and successfully surf the internet.

The steps are not limited to being performed in the exact order illustrated and, unless explicitly stated herein, may be performed in other orders.
