Description

Connection request sending method and device, storage medium and electronic equipment

Technical Field

The present application relates to the field of communications technologies, and in particular, to a connection request sending method, an apparatus, a storage medium, and an electronic device.

Background

An Access Point Name (APN) is a network Access technology, and is a parameter that must be configured when an electronic device such as a mobile phone and a PAD accesses the internet, and it determines which Access method the electronic device accesses the network through, and different network Access points can Access different network ranges and Access methods. The APN is typically stored as subscriber subscription data in a HSS (Home subscriber server)/HLR (Home Location Register). When initiating a packet service, an electronic device where a user is located provides an APN to a Serving GPRS Support Node (SGSN)/Mobility Management Entity (MME). The SGSN/MME performs Domain Name resolution through a DNS (Domain Name Server) according to the provided APN, so as to obtain an IP address of the GGSN, and accesses the electronic equipment into a PDN (Packet data network) corresponding to the APN through the IP address. Different APNs correspond to different PDNs, which may be defined by the operator.

In 3GPP 24.301 it is specified that for the same APN no multiple PDN connection establishment is allowed. This can in some cases easily lead to problems. For example, when the electronic device accesses the internet using a default type APN and then uses an dun type APN to share the network with other electronic devices, although the APN accessing the internet is different from the APN sharing the network, the network terminal may regard the APN accessing the internet and the APN sharing the network as the same APN, so as to give a rejection response to the PDN connection request corresponding to the APN sharing the network, and the electronic device may not share the network with other electronic devices.

Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise. In addition, the terms "first" and "second" are used to distinguish a plurality of elements from each other. For example, a first packet data network connection may be referred to as a second packet data network connection, and similarly, a second packet data network connection may be referred to as a first packet data network connection, without departing from the scope of the present application. The first packet data network connection and the second packet data network connection are both packet data network connections, but they are not the same packet data network connection.

The embodiment of the application provides a connection request sending method and device, a storage medium and electronic equipment. Hereinafter, APN and network access point are synonymous, and PDN connection and packet data network connection are synonymous.

Fig. 1 is a schematic diagram of a connection request sending system according to an embodiment of the present application. The connection request sending system comprises a client and a network, wherein the client comprises a mobile phone, a PAD, a PC and other devices, and the network comprises an SGSN (Serving GPRS Support Node), an MME (Mobility Management Entity) and other devices.

The client sends a first packet data network connection request to the network, the network sends a request receiving and refusing message to the client after receiving the first packet data network connection request sent by the client, the request receiving and refusing message comprises a message of accepting the first packet data network connection request and a message of refusing the first packet data network connection request, and finally sends service content returned based on the first packet data network connection request to the client after sending the message of accepting the first packet data network connection request to the client.

Referring to fig. 2, fig. 2 is a schematic flow chart of a connection request sending method provided in an embodiment of the present application, which is applied to a client, where the method mainly includes steps 101 to 106, and a specific flow may be as follows:

101, obtaining a sending instruction of a first packet data network connection request, where the first packet data network connection request carries first network access point information.

The network Access Point (APN) determines which access way the client accesses the network. There are many types of external networks that can be accessed by a client, for example: internet, WAP web site, internal network of group enterprise and internal special network of industry. The range and access mode of different network access points are different, how the network end knows which network the client needs to access after activation, and thus allocates the IP of which network is to be distinguished by the network access point, that is, the network Access Point (APN) determines which network the client accesses by which access mode. Each user of the access network can communicate with other users on the network, and a Packet Data Network (PDN) is responsible for transparent error-free transmission of data therebetween, i.e. the packet data network is intended to provide data transmission services.

The sending of the first packet data network connection REQUEST (ESM MSG PDN CONNECTIVITY REQUEST) may be triggered upon detection of generation of the first packet data network connection REQUEST. If the sending instruction triggering the first packet data network connection request is detected, the sending instruction of the first packet data network connection request is obtained, and the sending instruction of the first packet data network connection request carries the first network access point information. The carried first network access point information can be obtained through direct acquisition or indirect acquisition. It can be understood that, when the network access point parameter in the first packet data network connection request is not empty, the first network access point information corresponding to the network access point parameter is directly obtained; when the network access point parameter in the first packet data network connection request is empty, default network access point information is adopted, the default network access point information is provided by an HSS (home subscriber server), namely, determined by a SIM card of the client, and thus, taking the default network access point information as the first network access point information can be understood as indirectly acquiring the first network access point information. Wherein the first network access point information includes a name and a type of the first network access point. The type of the first network access point includes default type, mms type, submit (Secure User Plane Location) type, dun (Dial Up network) type, hipri type, and the like.

102, it is detected whether the client has established a second packet data network connection.

That is, whether a packet data network connection is established by the client is detected, and if the packet data network connection is established, the packet data network connection is used as a second packet data network connection. Information about the packet data network connection is stored in the client or detected via the network connection data.

If the client has established the second packet data network connection, step 103 is executed; if the client does not establish the second packet data network connection, step 106 is executed.

Second network access point information in the second packet data network connection is obtained 103.

And acquiring second network access point information in the second packet data network connection according to the established second packet data network connection. Wherein the second network access point information includes a name and a type of the second network access point.

And 104, comparing the first network access point information with the second network access point information to obtain a comparison result.

Specifically, step 104 includes: acquiring the name and the type of a first network access point in the first network access point information and the name and the type of a second network access point in the second network access point information; comparing the name and the type of the first network access point with the name and the type of the second network access point; if the name and the type of the first network access point are the same as those of the second network access point, determining that the comparison result is the same; and if the name of the first network access point is different from the name of the second network access point, or the type of the first network access point is different from the type of the second network access point, determining that the comparison result is different. Further, whether the name of the first network access point is the same as the name of the second network access point is judged; if the name of the first network access point is different from the name of the second network access point, determining that the comparison result is different; if the name of the first network access point is the same as that of the second network access point, judging whether the type of the first network access point is the same as that of the second network access point; if the type of the first network access point is different from that of the second network access point, determining that the comparison result is different; and if the type of the first network access point is the same as that of the second network access point, determining that the comparison result is the same. Or whether the type of the first network access point is the same as the type of the second network access point may be judged first, and then whether the name of the first network access point is the same as the name of the second network access point may be judged.

The name and the type of the first network access point are different from those of the second network access point, and the comparison result is determined to be different; and if the name and the type of the first network access point are the same as those of the second network access point, determining that the comparison result is the same.

And 105, sending a first packet data network connection request to the network terminal according to the comparison result.

Wherein, the comparison results comprise the same and different. Specifically, step 105, comprises: if the comparison result is the same, the first packet data network connection request is forbidden to be sent; and when the comparison result is different, sending a first packet data network connection request.

It can be understood that, when the comparison result is different, it is determined that the first network access point and the second network access point are different network access points, and the different network access points allow different paths of packet data network connections to be established. For example, default type network access points and dun type network access points are different network access points, allowing different paths of packet data network connections to be established. Thus, a first packet data network connection request is sent. And when the comparison result is the same, determining that the first network access point and the second network access point are the same network access point and the same network access point, and not allowing the establishment of the multi-path packet data network connection. Thus, sending the first packet data network connection request is prohibited.

And 106, sending a first packet data network connection request to the network terminal.

If the client does not establish the second packet data network connection, it means that the first packet data network connection to be established by the first packet data network connection request is the first packet data network connection established by the client, and there will be no case of multiple packet data network connections, that is, there will be no case of multiple network access points, and there will be no case of giving a rejection response to the packet data network connection requests corresponding to different network access points. Therefore, the first packet data network connection request can be directly sent to the network side.

Further, after sending the first packet data network connection request to the network side, the method further includes: receiving a request receiving and refusing message sent by a network terminal, wherein the request receiving and refusing message comprises a message for receiving a first packet data network connection request; and receiving the service content returned by the network terminal based on the first packet data network connection request. The network side responds to the first packet data network connection request according to the type of the first network access point in the first packet data network connection request, and returns corresponding service content. And the client receives the service content returned by the network terminal based on the first packet data network connection request.

Before sending a first packet data network connection request, the embodiment of the application detects whether a first network access point of a first packet data network connection to be established and a second network access point of a second packet data network connection established are the same network access point, namely, information of the first network access point is compared with information of the second network access point, and then the first packet data network connection request is sent to a network terminal according to a comparison result. In this way, before the client sends the first packet data network connection request, the first packet data network connection request is detected and compared, so as to avoid the situation that a rejection response is given to the packet data network connection requests corresponding to different network access points.

Fig. 3 is another schematic flow chart of a connection request sending method provided in an embodiment of the present application, where the connection request sending method is applied to a client. The connection request sending method mainly comprises steps 201-206, and the specific flow can be as follows:

a sending instruction of a first packet data network connection request is obtained 201, where the first packet data network connection request carries first network access point information, and the first network access point information includes a first network access point name and a first network access point type.

It is detected 202 whether the client has established a second packet data network connection, wherein the second packet data network connection is a packet data network connection corresponding to a second network access point having the same name as the first network access point.

In this step, the detected second packet data network connection is a packet data network connection corresponding to a second network access point having the same name as the first network access point. Since it is considered that if the name of the second network access point in the second packet data network connection is different from the name of the first network access point, it is not possible to be the same network access point and no detection is necessary. Thus, not all second packet data network connections are detected, but only the packet data network connection corresponding to the second network access point having the same name as the first network access point.

If the client has established the second packet data network connection, step 203 is executed; if the second packet data network connection is not established, step 206 is performed.

The type of the second network access point in the second packet data network connection is obtained 203.

The second network access point information in the second packet data network connection includes the name and type of the second network access point, and since the name of the second network access point is the same as the name of the first network access point, only the type of the second network access point needs to be acquired in this step.

And 204, comparing the type of the first network access point with the type of the second network access point to obtain a comparison result.

Since the name of the first network access point is the same as the name of the second network access point, the type of the first network access point is compared with the type of the second network access point to obtain a comparison result.

If the type of the first network access point is the same as that of the second network access point, the comparison result is the same; and if the type of the first network access point is different from that of the second network access point, the comparison result is different. It can be understood that, since the name of the first network access point and the name of the second network access point are already the same, as long as the type of the first network access point is different from that of the second network access point, the comparison result is different, otherwise, the comparison result is the same.

205, sending a first packet data network connection request to the network according to the comparison result.

Specifically, when the comparison results are the same, the first packet data network connection request is prohibited from being sent; and when the comparison result is different, sending a first packet data network connection request.

It can be understood that, when the comparison result is different, it is determined that the first network access point and the second network access point are different network access points, and the different network access points allow different paths of packet data network connections to be established. Thus, a first packet data network connection request is sent. And when the comparison result is the same, determining that the first network access point and the second network access point are the same network access point and the same network access point, and not allowing the establishment of the multi-path packet data network connection. Thus, sending the first packet data network connection request is prohibited.

206, sending the first packet data network connection request to the network terminal.

That is, if a second packet data network connection is not established, where the second packet data network connection is a packet data network connection corresponding to a second network access point having the same name as the first network access point, the following is included: (1) the client has established a second packet data network connection, but the name of the second network access point in the second packet data network connection is different from the name of the first network access point. Since the name of the second network access point is different from the name of the first network access point, it means that the first network access point and the second network access point are different network access points, which allow different paths of packet data network connections to be established. (2) The absence of any second packet data network connection by the client, other than the first packet data network connection to be established, means that the first network access point is unlikely to have multiple packet data network connections. In both cases, the first packet data network connection request is sent directly to the network side.

Further, after sending the first packet data network connection request to the network side, the method further includes: receiving a request receiving and refusing message sent by a network terminal, wherein the request receiving and refusing message comprises a message for receiving a first packet data network connection request; and receiving the service content returned by the network terminal based on the first packet data network connection request.

According to the method and the device for sending the packet data network connection request, before the first packet data network connection request is sent, whether the packet data network connection corresponding to the second network access point with the same name as the first network access point is established or not is directly detected, if yes, the type of the first network access point is compared with the type of the second network access point, and then the first packet data network connection request is sent to a network end according to the comparison result. In this way, before the client sends the first packet data network connection request, the first packet data network connection request is detected and compared, so as to avoid the situation that a rejection response is given to the packet data network connection requests corresponding to different network access points. Meanwhile, only whether the packet data network connection corresponding to the second network access point with the same name as the first network access point is established is detected, and all the second packet data network connections are not required to be detected, so that the detection efficiency is improved.

Fig. 4 is a schematic flow chart of a connection request sending method according to an embodiment of the present application. The connection request sending method is applied to a network terminal. The method mainly comprises the following steps 301-307, and the specific process can be as follows:

301, receiving a first packet data network connection request sent by a client.

And 302, acquiring the first network access point information in the first packet data network connection request.

The first packet data network connection request includes first network access point information, the first network access point information including a name and a type of the first network access point.

303, detecting whether the network and the client have established the second packet data network connection.

All packet data network connections established by the client are stored in the network. Each packet data network connection includes information of a network access point corresponding to the packet data network connection, including a name and a type of the network access point, etc. The established second packet data network connection is established before receiving the first packet data network connection request sent by the client.

If the second packet data network connection has been established, go to step 304; if the second packet data network connection is not established, go to step 307.

Second network access point information in the second packet data network connection is obtained 304.

The second network access point information includes a name and a type of the second network access point.

And 305, comparing the first network access point information with the second network access point information to obtain a comparison result.

Specifically, step 305 includes: acquiring the name and the type of a first network access point in the first network access point information and the name and the type of a second network access point in the second network access point information; comparing the name and the type of the first network access point with the name and the type of the second network access point; if the name and the type of the first network access point are the same as those of the second network access point, determining that the comparison result is the same; and if the name of the first network access point is different from the name of the second network access point, or the type of the first network access point is different from the type of the second network access point, determining that the comparison result is different. Further, whether the name of the first network access point is the same as the name of the second network access point is judged; if the name of the first network access point is different from the name of the second network access point, determining that the comparison result is different; if the name of the first network access point is the same as that of the second network access point, judging whether the type of the first network access point is the same as that of the second network access point; if the type of the first network access point is different from that of the second network access point, determining that the comparison result is different; and if the type of the first network access point is the same as that of the second network access point, determining that the comparison result is the same. Or whether the type of the first network access point is the same as the type of the second network access point may be judged first, and then whether the name of the first network access point is the same as the name of the second network access point may be judged.

And 306, determining a request receiving and refusing message sent to the client according to the comparison result, wherein the request receiving and refusing message comprises a message for accepting the first packet data network connection request and a message for refusing the first packet data network connection request.

Specifically, when the comparison result is the same, a message (PDN CONNECTIVITY REJECT) rejecting the first packet data network connection request is sent to the client; and when the comparison result is different, sending a message for receiving the first packet data network connection request to the client.

It can be understood that, when the comparison result is different, it is determined that the first network access point and the second network access point are different network access points, and the different network access points allow different paths of packet data network connections to be established. Thus, a message is sent to the client accepting the first packet data network connection request. And when the comparison result is the same, determining that the first network access point and the second network access point are the same network access point and the same network access point, and not allowing the establishment of the multi-path packet data network connection. Thus, a message is sent to the client rejecting the first packet data network connection request.

307, sending a message to the client accepting the first packet data network connection request.

If the network side and the client side do not establish the second packet data network connection request, the first packet data network connection to be established by the first packet data network connection request is the first packet data network connection established by the client side, the situation of multiple packet data network connections does not exist, namely the situation of multiple network access points does not exist, and meanwhile, the situation of refusing replies to the packet data network connection requests corresponding to different network access points does not occur. Thus, a message is sent to the client accepting the first packet data network connection request.

It will be appreciated that the first packet data network connection is established after the client sends a message accepting the first packet data network connection request.

Further, after sending the message accepting the first packet data network connection request to the client, the method further comprises: and sending the service content responding to the first packet data network connection request to the client.

When a network terminal receives a first packet data network connection request sent by a client, the network terminal compares first network access point information in the first packet data network connection request with second network access point information in an established second packet data network connection, so as to determine whether to send a request receiving message or a request rejecting message to the client according to a comparison result. Therefore, after the network end receives the first packet data network connection request, the first packet data network connection request is detected and compared so as to quickly determine whether to accept the first packet data network request or reject the first packet data network request, and the situation that a reject reply is given to the packet data network connection requests corresponding to different network access points is avoided.

Fig. 5 is another flowchart illustrating a connection request sending method according to an embodiment of the present application, where the connection request sending method is applied to a network. The connection request sending method mainly comprises steps 401-407, and the specific flow can be as follows:

401, a first packet data network connection request sent by a client is received.

First network access point information in the first packet data network connection request is obtained 402, where the first network access point information includes a name and a type of the first network access point.

And 403, detecting whether a second packet data network connection is established between the network side and the client side, wherein the second packet data network connection is a packet data network connection corresponding to a second network access point with the same name as the first network access point.

If the second packet data network connection has been established, go to step 404; if the second packet data network connection is not established, step 407 is executed.

The type of the second network access point in the second packet data network connection is obtained 404.

And 405, comparing the type of the first network access point with the type of the second network access point to obtain a comparison result.

For a specific comparison method, please refer to the description in step 204, which is not repeated herein.

And 406, determining, according to the comparison result, a request receiving and rejecting message sent to the client, where the request receiving and rejecting message includes a message for accepting the first packet data network connection request and a message for rejecting the first packet data network connection request.

Specifically, when the comparison results are the same, sending a message rejecting the first packet data network connection request to the client; and when the comparison result is different, sending a message of accepting the first packet data network connection request to the client.

407, sending a message to the client accepting the first packet data network connection request.

In this way, the client establishes the first packet data network connection after sending the message accepting the first packet data network connection request.

After the network end receives the first packet data network connection request, the first packet data network connection request is detected and compared to quickly determine whether to accept the first packet data network request or reject the first packet data network request, so that the situation that a reject reply is given to the packet data network connection requests corresponding to different network access points is avoided.
