Obviously, the described The embodiments are only some of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0066] see figure 1 , is a schematic diagram of the first embodiment of the method for the terminal to obtain the address of the management platform provided by the present invention.

[0067] The method is applied to the terminal side, the terminals include various Internet of Things terminals, handheld terminals or mobile terminals, and the terminals support GPRS (General Packet Radio Service, General Packet Radio Service) data services, including but not limited to mobile phones, electricity meters , POS machines, etc.

[0068] The method includes:

[0069] S101. Send a packet data protocol context activation request to a network side, where the packet data protocol context activation request includes a first address configuration parameter and a second address configuration parameter.

[0070] The first address configuration parameter is used to request the network side to configure the IP address of the terminal, and the second address configuration parameter is used to request the network side to configure the IP address of the management platform or the IP address of the DNS domain name resolution server.

[0071] S102: Receive a response from the network side to the packet data protocol context activation request, obtain the IP address of the terminal according to the first address configuration parameter returned by the network side, and obtain the IP address of the management platform according to the second address configuration parameter returned by the network side.

[0072] see figure 2 , is a schematic diagram of the second embodiment of the method for the terminal to obtain the address of the management platform provided by the present invention.

[0073] The method is applied to the network side, including:

[0074] S201: Receive a packet data protocol (PDP) context activation request sent by a terminal.

[0075] S202, in response to the packet data protocol PDP context activation request, configure the IP address of the terminal for the first address configuration parameter; configure the second address configuration parameter according to the preset IP address of the management platform or the IP address of the DNS domain name resolution server; The IP address of the management platform or the IP address of the DNS domain name resolution server is the most recently updated address.

[0076] S203. Send a response message to the terminal, where the response message includes a first address configuration parameter and a second address configuration parameter.

[0077] see image 3 , is a schematic diagram of the third embodiment of the method for the terminal to obtain the address of the management platform provided by the present invention.

[0078] In the third embodiment of the present invention, the terminal supports GPRS data services, the network is specifically a packet data protocol core network, and the network side includes SGSN, GGSN, and a management platform.

[0079] S301, the terminal sends a packet data protocol PDP activation request to the SGSN, where the activation request includes a first address configuration parameter and a second address configuration parameter.

[0080] In the third embodiment of the present invention, the terminal supports GPRS data services, and the terminal has a built-in network-specific APN (Access Point Name, access point), user name and password for security authentication and network access when GPRS is activated. The terminal sends a PDP context activation request to an SGSN (Serving GPRS Support Node, Serving GPRS Support Node), and the PDP context activation request includes an APN field and a PCO (Protocol Configuration Options) field. The APN field is used for network access authentication, and the PCO field contains two configuration parameters, which are a first address configuration parameter and a second address configuration parameter. The first address configuration parameter is used to request the network side to configure the IP address of the terminal, and the second address configuration parameter is used to request the network side to configure the IP address of the management platform or the IP address of the DNS domain name resolution server.

[0081] S302, the SGSN performs terminal identity authentication, and forwards the PDP context activation request to the GGSN.

[0082] After receiving the PDP activation request of the terminal, the SGSN obtains the authentication judgment standard information from the GGSN, and judges whether to reject or pass the activation request of the terminal. When the SGSN uses the APN information in the activation request for authentication, after the authentication is passed, it forwards the PDP context activation request to the GGSN.

[0083] S303, the GGSN configures the first address configuration parameter and the second address configuration parameter, and sends a response message to the SGSN.

[0084] The GGSN responds to the PDP context activation request forwarded by the SGSN, and at the same time performs data configuration on the first address configuration parameter and the second address configuration parameter in the PCP field in the request message according to the actual situation, and then configures the configured first address configuration The parameters and the second address configuration parameters are returned to the SGSN. During specific implementation, the GGSN configures the terminal's local IP address for the terminal, and the configured first address parameter is configured as the terminal's IP address.

Preferably, when the IP address of the management platform is updated, the management platform sends an update request to the GGSN, and the GGSN receives the update request from the management platform and stores the most recently updated IP address of the management platform. Therefore, the GGSN stores the IP address of the management platform, which is the most recently updated IP address. In this way, when the GGSN configures the second address configuration parameter, the second address configuration parameter carries the latest IP address of the management platform. Therefore, the terminal obtains the IP address updated in real time by the management platform.

[0086] Further, when there are multiple management platforms, in order to ensure the effective utilization of resources and the load balancing of the management platforms, in this embodiment of the present invention, the GGSN obtains the load situation of the management platforms, and according to the preset allocation strategy, is the terminal that sends the activation request. A management platform that matches the terminal is determined, and the second address configuration parameter is configured according to the determined IP address of the management platform that matches the terminal. During specific implementation, the preset allocation strategy is a strategy for ensuring load balance of the management platform, that is, the management platform with the smallest load is preferentially configured as the management platform matching the terminal. Of course, other allocation strategies can also be preset to realize the matching between the terminal and the management platform.

[0087]S304, the SGSN delivers the response message carrying the first address configuration parameter and the second address configuration parameter to the terminal. The SGSN sends a PDP context activation completion response to the terminal, and the response message carries two address configuration parameters.

[0088] S305, the terminal receives the response message, and obtains the IP address of the terminal and the IP address of the management platform.

[0089] If the second address configuration parameter is the IP address of the management platform, the terminal sets the IP address carried in the first address configuration parameter as the IP address of the terminal, and sets the IP address carried in the second address configuration parameter as the IP address of the management platform.

[0091] S307, the SGSN forwards the terminal connection request.

[0092] S308, the GSSN establishes and manages the connection of the platform.

[0097] Preferably, the embodiment of the present invention may further include a deactivation step.

[0098] S312, the terminal sends a packet data protocol packet data protocol context deactivation request to the network side.

[0099] When the terminal completes data communication with the management platform, it can send a PDP context deactivation request to the network side.

[0100] S313: The terminal receives the network side's response to the packet data protocol context deactivation request, and deletes the acquired IP address of the management platform.

[0101] When the terminal receives the network side's response to the PDP context deactivation request, it deletes the saved IP address of the management platform. In this way, the security of terminal network data can be guaranteed.

[0102] In another embodiment, when the terminal and the management platform are in a connected state, when the IP address of the management platform changes and the terminal and the platform are disconnected, the terminal may also send a PDP context deactivation request to the network side, and when the receiving to the deactivation response. The terminal re-sends the PDP context activation request to the network side, executes steps S301 to S311, and has completed the connection with the management platform.

When the terminal sends a PDP context activation request to the network side, the activation request carries two address configuration parameters, and the GGSN configures the IP address for the terminal. address, and configure the second address parameter according to the preset IP address of the management platform, so that the PDP context activation completion response returned by the network side carries the IP address of the management platform and the IP address of the terminal, so that the terminal can be activated through the PDP context Directly obtain the IP address updated in real time by the management platform, and then establish a connection with the management platform. In this implementation manner, the terminal can flexibly obtain the IP address of the management platform without programming the IP address of the management platform in advance, which is convenient for implementation.

[0104] On the other hand, from the perspective of future technological development, for security reasons, it is hoped that the terminal will not save any information related to the Internet of Things when it is not awakened. By applying the method of the present invention, only when the terminal initiates the activation of the PDP context, the relevant content is obtained from the network, thus ensuring the security of the data.

During specific implementation, the GGSN configures the terminal's local IP address for the terminal, and the configured first address parameter is configured as the terminal's IP address.

[0112] In the fourth embodiment of the present invention, the GGSN pre-stores the IP address of the DNS domain name resolution server. Preferably, when the IP address of the DNS domain name resolution server is updated, the DNS domain name resolution server sends an update request to the GGSN, and the GGSN receives the update request from the DNS domain name resolution server and saves the latest updated IP address of the DNS domain name resolution server. Therefore, the GGSN stores the IP address of the DNS domain name resolution server, which is the most recently updated IP address. In this way, when the GGSN configures the second address configuration parameter, the second address configuration parameter carries the latest IP address of the DNS domain name resolution server. Therefore, what the terminal obtains will also be the real-time updated IP address of the DNS domain name resolution server. .
