It should be understood that the communication system to which the method of the embodiment of the present application may be applied may include more or fewer devices or devices, or may include devices or devices with similar functions.

The communication system shown in FIG. 1 may include three parts, namely a terminal device, a data network (DN), and an operator network.

Among them, the operator network may include network exposure function (NEF), network storage function (network function repository function, NRF), policy control function (PCF), unified data management (unified data management, UDM) ) Network function, application function (AF), authentication server function (authentication server function, AUSF), access and mobility management function (AMF), session management function (session management function, SMF) ), (radio) access network ((radio) access network, (R) AN), and user plane function (UPF), etc. In the above-mentioned operator network, the part other than the (wireless) access network part is called the core network part. For the convenience of description, the following takes (R)AN called RAN as an example for description. A device or entity used to implement any of the above-mentioned functions in a communication network may be referred to as a core network device.

The terminal device can establish a connection with the operator's network through an interface (such as N1, etc.) provided by the operator's network, and use services such as data and/or voice provided by the operator's network. The terminal device can also access the DN through the operator's network, and use the operator's service deployed on the DN and/or the service provided by a third party. Among them, the aforementioned third party may be a service party other than the operator's network and terminal equipment, and may provide other services such as data and/or voice for the terminal equipment. Among them, the specific form of expression of the aforementioned third party can be determined according to actual application scenarios, and is not limited here.

RAN is a sub-network of an operator's network, and an implementation system between service nodes and terminal equipment in the operator's network. To access the operator's network, the terminal device first passes through the RAN, and then can be connected to the service node of the operator's network through the RAN.

Access network equipment is a device that provides wireless communication functions for terminal equipment. Access network equipment includes, but is not limited to: next-generation base stations (gnodeB, gNB) in 5G, evolved node B (evolved node B, eNB), radio network controller (RNC), node B (node B) B, NB), base station controller (BSC), base transceiver station (base transceiver station, BTS), home base station (for example, home evolved nodeB, or home node B, HNB), baseband unit (baseBand unit, BBU), transmission point (transmitting and receiving point, TRP), transmission point (transmitting point, TP), mobile switching center, etc.

The AMF network function is the control plane network function provided by the operator's network, which is responsible for the access control and mobility management of terminal equipment accessing the operator's network, such as mobile status management, allocation of temporary user identification, authentication and authorization of users, etc. .

The SMF network function is a control plane network function provided by the operator network, and is responsible for managing the protocol data unit (PDU) session of the terminal device. The PDU session is a channel used to transmit PDUs, and terminal devices need to transmit PDUs to each other through the PDU session and the DN. The PDU session is established, maintained, and deleted by the SMF network element. SMF network elements include session management (such as session establishment, modification and release, including tunnel maintenance between UPF and RAN), UPF network element selection and control, service and session continuity (service and session continuity, SSC) mode selection, Session-related functions such as roaming.

The UPF network function is a gateway provided by the operator, and is a network function for the operator's network to communicate with the DN. UPF network functions include data packet routing and transmission, packet inspection, service usage reporting, quality of service (QoS) processing, lawful monitoring, upstream packet inspection, downstream packet storage and other user-related functions.

DN, also called packet data network (PDN), is a network located outside the operator’s network. The operator’s network can be connected to multiple DNs, and multiple services can be deployed on the DN to provide terminal equipment. Services such as data and/or voice. For example, the DN is the Internet, or the DN is the private network of a smart factory. The sensors installed in the workshop of the smart factory can be terminal devices. The sensor's control server is deployed in the DN, and the control server can provide services for the sensors. The sensor can communicate with the control server, obtain instructions from the control server, and transmit the collected sensor data to the control server according to the instructions. For another example, a DN is an internal office network of a company. The mobile phones or computers of employees of the company can be terminal devices, and the mobile phones or computers of employees can access information and data resources on the company's internal office network.

The UDM network function is a control plane network function provided by the operator. It is responsible for storing the subscriber permanent identifier (SUPI), credential, security context, and subscription data of subscribers in the operator’s network. And other information. Among them, SUPI will be encrypted first in the transmission process, and the encrypted SUPI is called a subscription concealed identifier (SUCI).

The information stored in the UDM network function can be used for authentication and authorization of terminal equipment accessing the operator's network. Among them, the contracted users of the above-mentioned operator's network may specifically be users who use the services provided by the operator's network, such as users who use China Telecom's mobile phone core card, or users who use China Mobile's mobile phone core card. The permanent contract identifier SUPI of the aforementioned subscriber may be the number of the mobile phone core card, etc. The credential and security context of the aforementioned subscriber may be a small file stored such as the encryption key of the mobile phone core card or information related to the encryption of the mobile phone core card for authentication and/or authorization. The aforementioned security context may be data (cookie) or token (token) stored on the user's local terminal (for example, mobile phone). The contract data of the aforementioned subscriber may be the supporting service of the mobile phone core card, such as the data package of the mobile phone core card or the use of the network. It should be noted that permanent identifiers, credentials, security contexts, authentication data (cookies), and tokens are equivalent to information related to authentication and authorization. In this application file, no distinction or restriction is made for the convenience of description. If no special instructions are given, the embodiments of the present application will be described using a security context as an example, but the embodiments of the present application are also applicable to authentication and/or authorization information in other expression modes. For descriptive purposes, the UDM network function is referred to as UDM for short.

The AUSF network function is a control plane network function provided by the operator, and is usually used for first-level authentication, that is, the authentication between the terminal device (subscriber) and the operator's network. After the AUSF receives the authentication request initiated by the subscriber, it can authenticate and/or authorize the subscriber through the authentication information and/or authorization information stored in the UDM, or generate the subscriber’s authentication and/or authorization information through the UDM. AUSF can feed back authentication information and/or authorization information to subscribers.

NEF is a control plane network function provided by operators. NEF opens the external interface of the operator's network to third parties in a safe manner. When SMF needs to communicate with a third-party network function, the NEF network function can be used as a relay for the communication between the SMF and the third-party network function. When the NEF network function is used as a relay, it can be used as the translation of the identification information of the subscriber and the translation of the identification information of the third-party network element. For example, when NEF sends the SUPI of the subscriber from the operator network to the third party, it can translate the SUPI into its corresponding external identity (identity, ID). Conversely, when NEF sends an external ID (ID used in a third-party network) to the operator's network, it can be translated into SUPI.

The PCF network function is a control plane function provided by the operator to provide a PDU session strategy to the SMF. Policies can include charging-related policies, QoS-related policies, and authorization-related policies.

Fig. 2 is an exemplary flowchart of a communication method in an embodiment of the application.

S210. The network device sends an RRC message or NAS message to a terminal, where the RRC message or NAS message contains Internet address information, and the Internet address information is used to access relevant information of a first area, where the first area is the terminal Geographical area.

Correspondingly, the terminal receives the RRC message or NAS message from the network device, so that the Internet address information can be obtained from the RRC message or NAS message.

The network device may refer to the device in the aforementioned operator's network, or may be the device in the access network. For example, the network device may be an AMF entity or a base station.

When the network device is an access network device, the access network device may send Internet address information to the terminal through an RRC message; when the network device is a core network device, the core network device may send Internet address information to the terminal through a NAS message.

In a possible implementation manner, the relevant information of the first area may include the local information of the first area, for example, introduction of local customs, convenience information, detailed maps, catering, discount information for businesses, community activity information, Second-hand trading information, etc. The Internet address information used to access the related information of the first area may be referred to as Internet address information corresponding to the first area.

Optionally, when the terminal initially camps on or accesses a serving cell, a serving access network device, or a serving AMF entity, the network device may also send the Internet address information to the terminal. It is understandable that when the terminal changes the serving cell, serving access network equipment or serving AMF entity, the terminal can obtain new Internet address information from the currently served network equipment, that is, the Internet address information can follow the terminal’s Mobile updates do not require user involvement.

The related information of the first area can be stored in a server in the data network, and the server can be accessed through Internet address information, so that the related information of the first area can be obtained.

In this way, from the perspective of the terminal, no matter where the terminal moves to, the user can easily and quickly obtain the relevant information of the local area (ie the first area) of the location, corresponding to the Internet address information that provides local information. The content server can provide comprehensive information, and can be used as a platform to aggregate scattered various types of local information. Information acquisition is "minimalist for users" (that is, it is very convenient for users to obtain information), and is easy to promote and use. The tentacles go deep into any place that wireless signals can reach, including remote rural areas, mountainous areas, etc., to build a true information society; for operators, it is a natural advantage for operators to provide access addresses for local information through base stations all over the country. With the help of unique resources to achieve differentiated competition with Internet service providers, Internet manufacturers cannot follow up, and are exclusive and exclusive. This method opens up a new blue ocean for operators. In terms of business model, operators can operate their own content servers that provide local information. For example, they can be handed over to business halls at all levels for their own operation and management. They can obtain commercial returns through advertising, video subscription, information release, and e-shop entry. It can be leased to a third party for operation, for example, leased to the local government for operation, profitable by renting the entrance address, and even some areas are operated by themselves, and other areas are leased to others for operation. Because the local information content server can provide comprehensive information, it has more user stickiness. For local merchants/enterprises/government/property, etc.: it provides a platform for publishing information, which is more efficient and can be used as a further extension of the advertising industry, especially for small and medium-sized businesses to provide an advertising platform that is more locally targeted. Compared with a single-purpose mobile phone application that provides services based on location but provides information in a centralized manner, the information provided by the content server that provides local information linked to the Internet address can provide richer and more comprehensive information. Decentralized maintenance makes information updates more timely. In addition, there is no need to turn on the global positioning system (GPS), and it can be used without even installing a mobile client program, so it is more competitive.

When the network device is an access network device, Internet address information can be configured on the access network device, so that when the terminal moves within the service range of the access network device, the access network device can send the Internet address information. Alternatively, the access network device may be configured with a corresponding relationship between the Internet address information and the serving cell, so that when the terminal moves to which serving cell, the access network device will send the terminal corresponding to the serving cell according to the corresponding relationship. Internet address information.

When the network device is a core network device, the core network device can be configured with Internet address information, so that when the terminal moves within the management range of the core network device, the core network device can send the Internet address information to the terminal . Alternatively, the core network device may be configured with a corresponding relationship between the Internet address information and the access network device. In this way, when the terminal moves within the service range of which access network device, the core network device can report the corresponding relationship. The terminal sends the Internet address information corresponding to the access network device. Alternatively, the core network device may be configured with a corresponding relationship between the serving cell and the Internet address information, so that when the terminal moves to which serving cell, the core network device can send to the terminal the Internet corresponding to the serving cell according to the corresponding relationship. Address information.

Wherein, the areas related to the information accessible by the Internet address information corresponding to multiple serving cells may be completely different, or completely the same, or may partially overlap. For example, the Internet address information corresponding to different service cells may all be related information used to visit Pudong District. For another example, the Internet address information corresponding to one serving cell can be used to access related information about Jinqiao Road and Yunshan Road, and the Internet address information corresponding to another serving cell can be used to access related information about Jinqiao Road and Xinjinqiao Road.

The Internet address information may be IP address information, universal website information, or domain name address information. For example, an example of the Internet address information is: http://aabb.com, or http://201.12.101.10.

The information related to the first area may include one or more of the following information: information in the first area, information in the second area adjacent to the first area, and the third area including the first area and the second area. Information in the area. This can provide the terminal, that is, more choices to the user, so as to better meet the needs.

For example, when the terminal is located at Jinqiao Road, Pudong District, Shanghai, the first area may be Jinqiao Road, the second area may be Yunshan Road near Jinqiao Road, and the third area may be Pudong District or Shanghai.

The information in any area may include one or more of the following information in the area: traffic information, weather information, geographic information, diet information, and so on.

The Internet address information may include one or more Internet addresses. In the case where the Internet address information includes multiple Internet addresses, the multiple Internet addresses may correspond to multiple regions one-to-one, or correspond to multiple types of information.

When the multiple Internet addresses correspond to multiple areas one-to-one, in one implementation, the areas corresponding to the multiple Internet addresses may be adjacent. For example, the area corresponding to one Internet address is Jinqiao Road, and the other The area corresponding to the Internet address is Yunshan Road; in another implementation, the areas corresponding to the multiple Internet addresses may be in a containment relationship. For example, one of the areas corresponding to the Internet address is Jinqiao Road, and the area corresponding to another Internet address is It is Pudong District, and even the area corresponding to an Internet address is Shanghai; in another implementation manner, the areas corresponding to the multiple Internet addresses may include adjacent relationships or containment relationships. Or, when the multiple Internet addresses correspond to multiple areas one-to-one, there may be overlaps between the multiple areas.

The multiple Internet addresses may respectively correspond to different types of information in the first area. For example, one of the Internet addresses corresponds to weather information in the first area, and the other Internet address corresponds to traffic information in the first area.

The Internet address information may also include a character string name corresponding to the address indicated by the Internet address information. For example, the Internet address information may include http://aabb.com and "Jinqiao Road", or the Internet address information may include http://ccdd.com and "Pudong District". In this way, the user can learn more intuitively what information the address corresponds to, so that the needs of the user can be better met.

After the terminal receives the Internet address information, it can submit the Internet address information to a higher layer (for example, the operating system of the terminal), and the higher layer saves the Internet address information or updates the previously saved Internet address information. Or, after the terminal receives the Internet address information, it can be saved by its application service (AS) layer or non-access stratum (NAS), and then transmitted to the server when the higher layers of the terminal need to use it. High-level.

S220: The terminal accesses related information of the first area based on the Internet address information.

For example, when the user of the terminal needs to access local information (that is, the information of the first area), the Internet address information can be linked to a server that provides relevant information of the first area, thereby obtaining relevant information of the first area.

For example, an entry or software can be provided on the mobile phone operating system. After the user clicks on the entry or software, the mobile phone can open the Internet address information to link to the corresponding server.

For example, when the Internet address is http:///aabb.com, after the user clicks on the address, the mobile phone automatically uses a web browser to open the website. Terminals located in different service areas may open different URLs. For example, the web addresses opened by terminals located in different serving cells correspond to the geographic areas covered by their respective serving cells. Of course, the Internet address information received by terminals corresponding to multiple cells, access network devices, or core network devices may be all the same, or may be partially the same, or may be completely different. In other words, the URLs opened by terminals served by different cells, access network equipment, or core network equipment may be the same or different, which is not limited in the embodiment of the present application.

Alternatively, the terminal can integrate the Internet address information received from the network device into the browser software. For example, the Internet address information can be integrated into the browser software as a bookmark or a webpage in a favorites folder. The name of the bookmark or webpage An example of is local information or local treasure, and the bookmark or web page is linked to the Internet address information. Alternatively, a link or icon on the desktop of the terminal (such as a mobile phone) can be linked to the Internet address information.

When the user needs to access local information, he directly clicks the bookmark, the webpage, the link or the icon, and the operating system of the terminal can directly open the corresponding Internet address information, thereby presenting the user with the local information.

After the terminal moves, or after changing the current serving cell or camping cell, the terminal will retrieve the Internet address information, and then automatically update the bookmark, webpage, link or icon to the Internet address information.

In the communication method of the embodiment of the present application, optionally, the network device can actively send Internet address information to the terminal, and the terminal saves the Internet address information after receiving the Internet address information, and then waits for the user to request it through the Internet on the terminal Address information to access the relevant information of the first area.

Alternatively, the network device may send Internet address information to the terminal only at the request of the terminal. As shown in Figure 3, in S310, the terminal sends request information to the network device to request Internet address information corresponding to the first area to which the terminal belongs; after receiving the request information, the network device sends the first request information to the terminal in S320. The Internet address information corresponding to the area. In S330, the terminal accesses the related information of the first area based on the Internet address information corresponding to the first area. In FIG. 3, S320 can refer to S210, and S330 can refer to S220, which will not be repeated here.

When a network device actively sends Internet address information to the terminal, if the network device is an access network device, in some possible implementation manners, the access network device may broadcast the Internet address information in the system information of the cell. The terminal receives the system information of the serving cell, and obtains Internet address information from the system information. Wherein, the access network device may use a separate system information block (SIB) to send Internet address information, and the terminal obtains the Internet address information by reading the SIB.

When a network device actively sends Internet address information to a terminal, if the network device is an access network device, in other possible implementations, the access network device can send the Internet address information to the terminal when the terminal enters the RRC connection state terminal. For example, the access network device may send Internet address information to the terminal in the RRC connection establishment message.

When a network device sends Internet address information to the terminal at the request of the terminal, if the network device is an access network device, the network device can send an on-demand SIB to the terminal at the request of the terminal. The on-demand SIB sends Internet address information to the terminal. The on-demand SIB may also be called other SIB. Sending Internet address information through on-demand SIB can save wireless resources.

For example, the terminal may send a dedicated random access channel (RACH) preamble to the access network device, and request the base station to send the on-demand SIB containing the Internet address information corresponding to the first area through the dedicated RACH preamble; After receiving the dedicated RACH preamble, the network access device can send an on-demand SIB to the terminal, and the on-demand SIB carries Internet address information. After receiving the on-demand SIB, the terminal can obtain Internet address information from the on-demand SIB.

When a network device sends Internet address information to a terminal at the request of a terminal, if the network device is an access network device, in other possible implementations, the terminal sends a dedicated RRC message to the access network after entering the RRC connection state. The network device requests the access network device to send Internet address information, and the access network device sends the Internet address information to the terminal through a dedicated RRC response message. For example, the terminal sends a local address request RRC message to the access network device, and the access network device sends The terminal device replies with a local address response RRC message, and the local address response RRC message carries Internet address information.

When a network device sends Internet address information to the terminal at the request of the terminal, if the network device is a core network device, the network device can send a NAS message at the request of the terminal, and send the Internet address information to the terminal through the NAS message.

For example, the terminal can send request information to the core network device through a NAS message to request Internet information corresponding to the first area; after receiving the NAS message, the core network device sends the NAS message to the terminal according to the request information in the NAS message, and The Internet address information corresponding to the first area is carried in the NAS message. For example, the terminal sends a local address request NAS message to the core network device, and the core network device replies to the terminal device with a local address response NAS message. The local address response NAS message carries Internet address information.

In the embodiments of the present application, optionally, before the network device sends Internet address information to the terminal, the network device may send instruction information to the terminal, indicating that the network device supports the Internet that provides information related to the geographic area where the terminal is located. Address information, or indicating that the network device can provide Internet address information, through which information about the geographic area where the terminal is located can be accessed.

Further, optionally, as shown in S410 in FIG. 4, the network device sends instruction information to the terminal, indicating that it supports providing the Internet address information. Correspondingly, in S420, the terminal can learn from the indication information that the network device has the ability to provide address information related to the geographic area where the terminal is located, and send request information to the network device to request the Internet address information; in S430 In S440, the network device sends the Internet address information to the terminal according to the request of the terminal; in S440, the terminal accesses relevant information of the geographic area to which it belongs based on the Internet address information. The method shown in Figure 4 helps avoid waste of resources. In Fig. 4, S420 can refer to S310, S430 can refer to S210, and S440 can refer to S220, which will not be repeated here.

When the network device is an access network device, in some possible implementation manners, the network device may send the instruction information to the terminal through system information. For example, the access network device may broadcast the indication information in the system information of the cell, indicating whether the cell supports providing the terminal with Internet address information corresponding to the geographic area where the terminal is located. The terminal learns that the access network device supports the function of providing Internet address information corresponding to the geographic area where the terminal is located by reading the system information of the current serving cell (or camping cell). After learning that the access network device has this function, the terminal can request Internet address information from the access network device through RRC signaling. Among them, the terminal can immediately request Internet address information from the access network device, or the terminal device can request Internet address information from the access network device when the user needs it.

When the network device is a core network device, in some possible implementations, the network device can send instructions to the terminal during the registration process of the terminal, such as the initial registration or the mobility update registration process, to inform the terminal whether the network device is Support to provide the terminal with Internet address information corresponding to the geographic area where the terminal is located. For example, the network device may send the instruction information to the terminal in the registration response message.

In the following, with reference to FIG. 5, taking the access network device as a base station as an example, it is described how the terminal in this application obtains Internet address information for accessing related information of the geographic area from the access network device.

For the convenience of description, the Internet address information used to access the related information of the geographic area where the terminal is located is simply referred to as the Internet address information corresponding to the geographic area where the terminal is located.

S510: The base station broadcasts the system information of the current serving cell of the terminal. The system information carries indication information. The indication information is used to indicate that the cell supports the function of providing the terminal with Internet address information corresponding to the relevant information of the geographical area. The terminal learns that the base station supports this function by reading the system information of the current serving cell (or camping cell).

S530: After reading the system information and knowing that the base station supports the function, the terminal sends a request to the serving base station to obtain Internet address information corresponding to the geographic area where the terminal is located.

Optionally, if the terminal is in an idle state, S520 needs to be performed before S530, that is, the terminal needs to enter the RRC connected state before sending a request to the serving base station through a dedicated RRC message.

Or, after the terminal reads the system information and learns that the base station supports this function, it may not immediately send a request to the serving base station, but when the user needs the Internet address information corresponding to the geographic area where the user is located, it sends the request to the serving base station to obtain its own location. Internet address information corresponding to the management area.

The implementation of sending the request to the serving base station when the user needs the Internet address information can save communication resources and save the power consumption of the terminal compared with sending the request to the serving base station immediately after the terminal knows that the base station supports the function. This is because the latter, regardless of the user's need for Internet address information, needs to connect to the RRC when the terminal is in the idle state, and enter the RRC connection state to request Internet address information from the base station, while the former is only in the idle state when the user needs Internet address information. The terminal only needs to perform the RRC connection state.

The request may be a single RRC message or information in an RRC message, which is not limited in this application.

S540: The base station sends an RRC message carrying Internet address information to the terminal through the serving cell.

In the following, in conjunction with FIG. 6, taking the core network device as an AMF entity as an example, it is introduced how the terminal in this application obtains Internet address information for accessing relevant information of the geographic area where the terminal is located from the core network device.

Among them, the AMF entity is referred to as AMF for short. The Internet address information used to access the related information of the geographic area where the terminal is located is referred to as the Internet address information corresponding to the geographic area where the terminal is located.

S610: During the registration of the terminal (for example, initial registration or mobility update registration, etc.), the terminal sends a registration request (registration request) message to the AMF to request registration. This step can refer to the existing terminal registration process, which will not be repeated here.

S620. The AMF sends a registration accept message to the terminal, and in the message indicates to the terminal whether the AMF supports the function of providing the terminal with Internet address information corresponding to the geographic area where the terminal is located.

S640: After receiving the registration reception message and knowing that the AMF supports this function, the terminal sends a request to the AMF to obtain Internet address information corresponding to the geographic area.

Alternatively, after the terminal receives the registration reception message and learns that the base station supports the function, it does not immediately send a request to the AMF, but only sends a request to the AMF when the user needs Internet address information to obtain the Internet address information corresponding to the geographic area. If the terminal is in the idle state, S630 needs to be performed before S640, that is, the terminal needs to enter the RRC connection state before sending a request to the AMF.

The implementation of sending a request to the AMF when the user needs the Internet address information can save communication resources and save the power consumption of the terminal compared with sending the request to the AMF immediately after the terminal learns that the AMF supports the function. This is because the latter, regardless of the user's need for Internet address information, needs to connect to RRC when the terminal is in the idle state and enter the RRC connection state to request Internet address information from the AMF, while the former only works when the user needs Internet address information. The terminal only needs to perform the RRC connection state.

The request may be a single NAS message or information in a NAS message, which is not limited in this application. Alternatively, a new protocol layer can be introduced to send the request.

S650: After receiving the request from the terminal, the AMF determines the Internet address information corresponding to the geographic area where the terminal is located for the terminal.

Optionally, the Internet address information can be determined according to the address of the terminal. Further, the Internet address information can be determined for the terminal according to the serving cell to which the terminal belongs. For example, if the Internet address information corresponding to the local information has a corresponding relationship with the serving cell, the request information sent by the terminal to the AMF can carry the indication information of the serving cell where the terminal is currently located. In this way, the AMF can be based on the serving cell and the serving cell of the terminal. The correspondence relationship determines the Internet address information corresponding to the local information required by the terminal.

S660. The AMF sends a NAS message carrying Internet address information to the terminal.

In the communication method of this application, the network device is an access network device, and the Internet address information sent by the access network device to the terminal includes not only the Internet address of the local information of the first area to which the terminal belongs, but also the terminal and the first area. When the Internet address of the local information of the adjacent second area, optionally, the Internet address of the local information of the second area may be actively sent by the adjacent access network to the access network device, or it may be the access network device. The network access device actively obtains it from the adjacent access network device.

In some possible implementations, if the Internet address corresponds to the serving cell, that is, the Internet address is at the cell level, the two base stations can interact with each other when the interface between the base stations (such as Xn, X2, etc.) is established. Internet address. For example, base station 1 has cell 1 and cell 2, and base station 2 has cell 3 and cell 4. When the interface between base stations is established, base station 1 sends the corresponding Internet addresses of cell 1 and cell 2 to base station 2, and base station 2 will The Internet addresses corresponding to cell 3 and cell 4 are sent to base station 1.

In other possible implementations, if the Internet address corresponds to the base station, that is, the Internet address time is at the base station level, then when the interface between the two base stations is established between the base stations, base station 1 sends the Internet address corresponding to base station 1 to base station 2. 2 Send the Internet address corresponding to base station 2 to base station 1.

For example, as shown in FIG. 7, in S710, the serving base station of the terminal sends an Xn interface setup request (Xn setup request) message to the neighboring base station. In S720, the neighboring base station returns an Xn interface setup response (Xn setup response) message to the serving base station of the terminal, and the response message carries the Internet address corresponding to the neighboring base station. In S730, the serving base station sends a message to the serving cell's system information. The terminal sends Internet address information, and the Internet address information includes the Internet address corresponding to the serving base station and the Internet address corresponding to the neighboring base station. S730 can refer to the related content in S210, which will not be repeated here.

Or, in S720, the Xn interface establishment response message returned by the neighboring base station to the serving base station of the terminal carries the Internet address corresponding to the cell of the neighboring base station; in S730, the serving base station sends the Internet address to the terminal through the system information of the serving cell Information, the Internet address information includes the Internet address corresponding to the cell of the serving base station and the Internet address corresponding to the cell of the neighboring base station.

In the communication method of this application, optionally, the terminal can not only receive Internet address information from the cell (serving cell) where it resides or from the service access network device corresponding to the serving cell, but also can receive information from neighboring cells or Internet address information of neighboring access network devices. The Internet address information from the serving cell or the serving access network device may be the same or different from the Internet address information from the neighboring cell or the neighboring access network device, and the same may be completely the same or partly the same.

For example, as shown in Figure 8, in S810, the terminal may receive system information from the serving base station (or serving cell), obtain the Internet address information corresponding to the serving base station (or serving cell) from the system information, and save the Internet Address information or update the Internet address information on the terminal; in S820, the terminal can receive system information from a neighboring base station (or neighboring cell), and obtain the Internet address information corresponding to the neighboring base station (or neighboring cell) from the system information, and Save the Internet address information or update the Internet address information on the terminal.

It should be noted that although the above embodiments all relate to how the network device and the terminal transmit the Internet address information used to access the relevant information of the first area to which the terminal belongs, so that the terminal can access the first area based on the Internet address information. Related information of a region, but the communication method proposed in this application can also be applied to transmit other address information that can access external data networks between network devices and terminals. That is, it is not limited here that the Internet address information is only the relevant information used to access the first area.

In other words, each of the above-mentioned embodiments makes simple adaptive modifications, for example, something like "The terminal receives Internet address information from a network device, and the Internet address information is used to access related information in the first area, and the first area is the terminal The geographic area where the terminal is located; the terminal accesses the relevant information of the first area based on the Internet address information.” The description can be adapted accordingly to “the terminal receives the Internet address information from the network device, and the Internet address information is used to access the data network Related information, the terminal accesses the relevant information of the data network based on the Internet address information".
