The method for acquiring information provided by the embodiments of the present application is described in detail below with reference to the accompanying drawings through some embodiments and application scenarios thereof.

In the transmission control protocol/internet protocol (Transmission Control Protocol/Internet Protocol, TCP/IP) specification, 0.0.0.0 represents one set of: all unclear hosts and destination networks. 0.0.0.0 is not a real IP address, which represents all internet protocol version 4 (Internet Protocol version, ipv 4) addresses in the home. The port monitoring 0.0.0.0 is the port monitoring all the IP in the local.

For a PINE, the PINE may send a hypertext transfer protocol (HyperText Transfer Protocol, HTTP) message (HTTP message) based on user datagram protocol (User Datagram Protocol, UDP) +ip, which is then sent to a destination IP address of 0.0.0.0, which HTTP message is a broadcast for PIN discovery (PIN discovery), PIN server discovery (PIN server discovery), or the like.

For example, a PIN, such as a terminal, does not know the PIN server (PIN server) address, or does not know the administrator of a PIN, i.e., the IP address of the PEMC, and the terminal needs to discover the PIN server or PEMC first if it is to join a PIN, or wants to find the PIN server. At this time, the PINE may send an HTTP broadcast message to the PEGC, where the destination IP address of the broadcast message is 0.0.0.0, and the broadcast message is sent to all hosts in the network by default (the so-called host includes a PIN server or PEMC corresponding to all PINs). At this point, either the PINs erver or PEMC is included in all hosts by default.

However, in view of use efficiency, if the PEGC forwards the broadcast message to the PIN server or the PEMC after receiving the broadcast message of the PIN, the PIN server or the PEMC can send the address of the PIN server or the address of the PEMC to the PIN in response to the broadcast. Thus, the PINE actually finds the PIN server or PEMC, and then the PINE can choose to add a PIN or complete the search of the PIN.

PEGC is able to receive the broadcast message, but after receiving the broadcast message, the PEGC actions need to be defined and other 5G core network elements or application layer network elements need to be indicated to him. The PEGC receives the broadcast message first, then the PEGC can replace the destination IP address of 0.0.0.0 with the IP address of the PIN server or PEMC, so as to forward the broadcast message to the PIN server or PEMC, and the PEGC needs to obtain the PIN server address or PEMC address, i.e. the first information, and with this first information, the PEGC knows how to process the broadcast message after receiving the broadcast message addressed to 0.0.0, and needs to replace the destination IP address with which IP address. Otherwise, if the PEGC does not have the first information, it does not know who should be sent to after receiving the broadcast message, and it cannot process the broadcast message. For example, PEGC first needs to receive the broadcast message, identify it as a message to the destination IP address of 0.0.0.0, then PEGC identifies the message and modifies the destination IP address of the message to: the IP address of the pins, the IP address of the PEMC. And the destination IP of the message is identified, then the destination IP address is modified into the IP address of the PINs server, the IP address of the PEMC, which is the purpose of the first information, and finally the PEGC forwards the broadcast message to the PINs server or the PEMC.

In this embodiment of the present application, after receiving the PEMC or the pingserver of the broadcast message, the information related to the pingserver address, the PEMC address, the pingid, etc. is put into the response message of the broadcast message, and sent to the PINE through PEGC. Thus, the PINE obtains the ID of each PIN, and the corresponding PEMC, PINServer address, and the PINE can decide to add a PIN.

As shown in fig. 2, the embodiment of the present application provides a method 200 for acquiring information, which may be performed by a first communication device, in other words, the method may be performed by software or hardware installed in the first communication device, and the method includes the following steps.

S202: the method comprises the steps that first communication equipment receives a first message, the first message comprises first information, and the first information is used for forwarding a second message from second communication equipment to a server or a terminal corresponding to a first address when the first communication equipment receives the second message; the first message includes application layer signaling; the first information includes the first address.

In this embodiment, the first information is used for the first communication device to replace a destination IP address, such as 0.0.0.0, of the second message with a server or a terminal corresponding to the first address when receiving the second message from the second communication device, and then forward the second message to the server or the terminal corresponding to the first address.

In various embodiments of the present application, the first communication device may be PEGC; the second communication device may be a PINE; the third communication device is a server or terminal corresponding to the first address, and may be a PIN server (PIN server) or PEMC.

Optionally, the first address comprises an address of at least one third communication device, the third communication device comprising at least one of: the PIN server, PEMC, i.e. the first address comprises a PIN server address or a PEMC address.

The second message is used for discovering a third communication device or the second communication device, and comprises at least one of the following: the method is used for discovering the PIN server, the PEMC, the PINE and the terminal. Optionally, the second message is a broadcast message, for example, the destination IP address of the second message is 0.0.0.0, the second message may be an HTTP message, or any other message, and the destination IP address is 0.0.0.0.

In this embodiment, the first message may be from a PIN server or PEMC. For example, after the first communication device (PEGC) has an application layer interaction with the PIN server, the PIN server may send the first information to the PEGC; for another example, or after the PIN is established, the PEMC may send the first information to the PEGC through interaction of application layer signaling.

In various embodiments of the present application, the first information may include at least one of:

1) The first address comprising an address of at least one third communication device comprising at least one of: PIN server, PEMC.

2) A PIN provider identification ID for identifying the provider of the PIN service.

3) A space availability condition of the first information; wherein the first communication device is supported to use the first information when the first communication device is in a position corresponding to the space availability condition. That is, if the first communication device is at a position corresponding to the space availability condition, the first communication device may use the first information; and if the first communication equipment is out of the position corresponding to the space effectiveness condition, the first communication equipment does not use the first information.

According to the information acquisition method, the first communication device acquires the first information through receiving the application layer signaling, and the first information is used for forwarding the second information to the server or the terminal corresponding to the first address when the first communication device receives the second information from the second communication device, so that the PIN communication performance is improved. Optionally, on the basis of the embodiment shown in fig. 2, after the first communication device receives the first message, the method further includes: the first communication device receives the second message; the first communication device changing the destination IP address of the second message to the first address, the first address comprising an address of at least one third communication device; and the first communication equipment forwards the second message to a server or a terminal corresponding to the first address.

In this embodiment, after the first communication device forwards the second message to the server or the terminal corresponding to the first address, the method further includes: the first communication device forwards response information corresponding to the second message to the second communication device.

Optionally, the first information may further include an indication information. The indication information is used for indicating whether the first communication equipment directly sends the second message to the PEMC or the PINs erver or sends the second message to the PEMC or the PINs erver through 5GS after the first communication equipment receives the second message and replaces the destination IP address of the second message with the first address in the first information. The indication information is also obtained through application layer signaling, for example, a PIN server or PEMC, and is sent to the PEGC through application layer signaling.

When the first communication device receives the second message from the PINE and changes the destination IP address of the second message to the first address server or the terminal according to the first information, the first communication device may decide, according to the indication information, what manner the second message after changing the destination IP address is to be sent to the PEMC or the PIN server:

1) The first communication device forwards the second message to the server or the terminal corresponding to the first address through direct communication with the server or the terminal corresponding to the first address. In this example, for example, there is direct communication between the first communication device and the PEMC, and the first communication device directly sends the second message to the PEMC.

2) The first communication device forwards the second message to a server or terminal corresponding to the first address through a 5G system (5 GS). In this example, for example, when there is no direct connection between the first communication device and the PEMC, the first communication device sends a second message to the PEMC via 5 GS. The first communication device sends the second message to the base station RAN, then the RAN gives the UPF user plane function again, and then the UPF sends the second message to the PEMC or the pins server through the route again. The method is adopted when the first communication equipment and the PEMC are not in direct communication.

Optionally, on the basis of the embodiment shown in fig. 2, before the first communication device receives the first message, the method further includes: the first communication device sends a request message to a server or a terminal corresponding to the first address, where the request message is used to request to acquire or subscribe to the first information.

Optionally, the server or the terminal corresponding to the first address includes a third communication device, and the first message further includes the updated first information; the updated first information includes the updated first address; wherein the updated first information is sent when the third communication device changes, including at least one of:

1) The PIN server is changed, and the PIN server is the PIN server associated with the first communication device. For example, the PIN server corresponding to the first communication device changes.

The method of acquiring information according to further embodiments of the present application will be described in detail below with reference to fig. 3 and 4.

And then the PEMC or the PIN server receives the second message and then sends a response message to the PINE. The first communication device decides whether to send the second message directly to the PEMC or the pinser or send the second message to the PEMC or the pinser through 5GS according to the indication information.

In the related art, how the PIN discovers the PIN server or PEMC is not defined yet, so that a PIN cannot be added, which affects PIN communication.

In order to describe the information acquisition method provided in the embodiments of the present application in detail, the following description will be made with reference to several specific embodiments.

Example 1

In this embodiment, PEGC obtains the first information through a PIN server, as shown in fig. 5, and this embodiment includes the following steps.

Step 1: the PEGC sends a first information acquisition or subscription request to the PIN server, the request being for obtaining the first information.

The first information is a PIN server address or PEMC address corresponding to a broadcast message (for PIN discovery), that is, after the PEGC receives the HTTP broadcast message, the message needs to be forwarded to the PIN server address or PEMC address contained in the first information.

The obtaining request further includes: location information served by the PEGC, IP address of the PEGC.

Step 2: the PIN server transmits the first information.

The first information may include the following: addresses of one or more PIN servers or PEMCs; the range of the PIN server or PEMC service, etc., as shown in table 1 below.

Table 1 first information example

The following steps 4 to 7 are common to embodiment two:

step 3: the pin may access the PEGC through a service set identification (Service Set Identifier, SSID), a password (password), which is issued by the PEMC.

Step 4: a PIN, or a terminal, sends an HTTP broadcast message (or simply HTTP message, broadcast message, HTTP message, etc.) to the PEGC, where the HTTP broadcast message is used to perform PIN discovery (this message may be any message), and the broadcast message may be an arbitrary HTTP message addressed to a destination IP address of 0.0.0.0.

Step 5: since the PEGC has previously received the first information through the application layer message, that is, after receiving the HTTP message with the destination IP address of 0.0.0.0, the message is for the PIN discovery, the PEGC may forward the HTTP message to the IP address of the PIN server or the IP address of the PEMC indicated in the first information.

That is, PEGC modifies the HTTP message to the destination IP address, which is either a PIN server address or a PEMC IP address; the message content is then unchanged.

Steps 6a,6b: the PEGC forwards the HTTP message to the PIN server or PEMC (this is the action of the PEGC after receiving the HTTP message); send the message to the replaced IP address (i.e., PIN server or PEMC)

Steps 7a,7b: after receiving the broadcast message, the PIN server or PEMC sends a response message to the PINE, wherein the response message comprises at least one of the following contents:

1) PEMC addresses, such as IP addresses, fully qualified domain names (Fully Qualified Domain Name, FQDN), uniform resource locators (Uniform Resource Locator, URL).

2) PINs server addresses, such as IP addresses, FQDNs, URLs.

3) PINID, which identifies a PIN managed by PEMC, or a PIN registered in PINServer.
