Description

Communication method and communication device

Technical Field

The present application relates to the field of communications, and more particularly, to a communication method and a communication apparatus.

Background

People always pay more attention to their own information. For example, people want to know information about shopping malls, information about living committees, information about cell properties, information about banks, information about accommodation, traffic information, and so on around their own location.

At present, people usually obtain their information by means of advertisement, signboard, notice or inquiry of passerby. This approach is less convenient. For example, when one wishes to know traffic information around, one does not know where to obtain it. The inconvenience of this method of obtaining information is particularly acute when people are traveling to a new location.

How to improve the convenience of people for acquiring surrounding information is a technical problem to be solved urgently.

With reference to the second possible implementation manner, in a third possible implementation manner, the request information may be a random access preamble. That is, the terminal may transmit a dedicated random access preamble to the access network device to request internet address information for accessing information related to a geographical area where the terminal is located, and then the access network device may transmit the internet address information to the terminal through an RRC message.

With reference to any one of the first to third possible implementation manners, in a fourth possible implementation manner, the internet address information may be carried in system information.

That is, the network device can inform the terminal in advance that it has the capability of providing internet address information for accessing information about a geographical area to which the terminal belongs. Therefore, the terminal can avoid requesting the internet address information from the network equipment under the condition that the network equipment does not have the capability, and the power consumption of the terminal can be saved.

For example, the terminal receives the indication information from the network device before sending the request information to the network device.

With reference to the fifth possible implementation manner, in a sixth possible implementation manner, the indication information may be carried in system information. That is, the access network device may inform the terminal that it has the capability of providing internet address information through the system information.

The mobility management functional entity may be a control plane functional entity, may be provided by an operator network, and is responsible for access control and mobility management of the terminal device accessing the operator network, for example, including functions of mobility state management, allocating a user temporary identity, authenticating and authorizing a user, and the like.

Fig. 1 is a schematic diagram of a communication system to which the method of the embodiments of the present application may be applied. It should be understood that the methods of the embodiments of the present application may be applicable to communication systems that include more or fewer apparatuses or devices, or may include devices or apparatuses with similar functionality.

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

The operator network may include a network open function (NEF), a network storage function (NRF), a Policy Control Function (PCF), a Unified Data Management (UDM) network function, AN Application Function (AF), AN authentication server function (AUSF), AN access and mobility management function (AMF), a Session Management Function (SMF), AN access network (radio) access network (R) AN, and a User Plane Function (UPF), etc. The part of the operator network described above, except for the (radio) access network part, is referred to as the core network part. For convenience of description, the (R) AN will be referred to as RAN as AN example. A device or entity in a communication network for implementing any of the above functions may be referred to as a core network device.

The terminal device may establish a connection with the carrier network through an interface (e.g., N1, etc.) provided by the carrier network, using data and/or voice, etc. services provided by the carrier network. The terminal device may also access the DN via an operator network, use operator services deployed on the DN, and/or services provided by a third party. The third party may be a service party other than the operator network and the terminal device, and may provide services such as data and/or voice for the terminal device. The specific expression form of the third party may be determined according to an actual application scenario, and is not limited herein.

The RAN is a sub-network of the operator network and is an implementation system between the service node and the terminal device in the operator network. The terminal device is to access the operator network, first through the RAN, and then may be connected to a service node of the operator network through the RAN.

An access network device is a device for providing a wireless communication function for a terminal device. Access network devices include, but are not limited to: next generation base station (G node B, gNB), evolved node B (eNB), Radio Network Controller (RNC), Node B (NB), Base Station Controller (BSC), Base Transceiver Station (BTS), home base station (e.g., home evolved node B, or home node B, HNB), Base Band Unit (BBU), transmission point (TRP), Transmission Point (TP), mobile switching center, etc. in 5G.

The AMF network function is a control plane network function provided by an operator network, and is responsible for access control and mobility management of terminal equipment accessing the operator network, including functions such as mobility state management, user temporary identity assignment, user authentication and authorization, and the like.

The SMF network function is a control plane network function provided by an operator network and is responsible for managing a Protocol Data Unit (PDU) session of a terminal device. A PDU session is a channel for transmitting PDUs, and a terminal device needs to transfer PDUs to and from the DN through the PDU session. The PDU session is established, maintained, deleted and the like by the SMF network element. The SMF network element includes session management (e.g., session establishment, modification, and release, including tunnel maintenance between the UPF and RAN), selection and control of the UPF network element, Service and Session Continuity (SSC) mode selection, roaming, and other session-related functions.

The UPF network function is a gateway provided by the operator and is a network function of the operator's network communicating with the DN. The UPF network functions include user plane related functions such as packet routing and transmission, packet detection, service usage reporting, quality of service (QoS) processing, lawful interception, uplink packet detection, downlink packet storage, and the like.

A DN, which may also be referred to as a Packet Data Network (PDN), is a network located outside an operator network, where the operator network may access multiple DNs, and multiple services may be deployed on the DNs, so as to provide services such as data and/or voice for a terminal device. For example, the DN is the internet, or the DN is a private network of an intelligent factory, a sensor installed in a workshop of the intelligent factory may be a terminal device, a control server with the sensor deployed in the DN may provide a service for the sensor. The sensor can communicate with the control server, obtain the instruction of the control server, transmit the sensor data gathered to the control server, etc. according to the instruction. For another example, the DN is an internal office network of a company, the mobile phone or computer of the employee of the company may be a terminal device, and the mobile phone or computer of the employee may access information, data resources, and the like on the internal office network of the company.

The UDM network function is a control plane network function provided by an operator and is responsible for storing information such as a subscriber permanent identifier (SUPI), a credential (trusted), a security context (security context), and subscription data of a subscribed user in an operator network. The SUPI is encrypted during transmission, and the encrypted SUPI is called a hidden subscriber identifier (SUCI).

These information stored by the UDM network function can be used for authentication and authorization of the terminal device to access the operator network. The subscriber of the operator network may be specifically a user using a service provided by the operator network, for example, a user using a mobile phone core card of china telecommunications, or a user using a mobile phone core card of china mobile, and the like. The permanent subscription identity SUPI of the subscriber may be the number of the core card of the mobile phone. The credentials and security context of the subscriber may be a small file stored with an encryption key of the core card of the mobile phone or information related to encryption of the core card of the mobile phone, and used for authentication and/or authorization. The security context may be data (cookie) or token (token) stored on the user's local terminal (e.g., cell phone), etc. The subscription data of the subscriber may be a service associated with the mobile phone core card, such as a traffic package or a network using the mobile phone core card. It should be noted that the information related to the permanent identifier, the credential, the security context, the authentication data (cookie), and the token equivalent authentication and authorization is not distinguished or limited in the present document for convenience of description. Unless otherwise specified, the embodiments of the present application will be described in the context of security, but the embodiments of the present application are also applicable to authentication, and/or authorization information in other expressions. For the purposes of this description, the UDM network function is simply referred to as UDM.

The AUSF network function is a control plane network function provided by an operator, and is generally used for primary authentication, i.e., authentication between a terminal device (subscriber) and an operator network. After receiving the authentication request initiated by the subscriber, the AUSF may authenticate and/or authorize the subscriber through the authentication information and/or authorization information stored in the UDM, or generate the authentication and/or authorization information of the subscriber through the UDM. The AUSF may feed back authentication information and/or authorization information to the subscriber.

The NEF is the operator-provided control plane network function. The NEF opens the external interface of the operator network to third parties in a secure way. When the SMF needs to communicate with a network function of a third party, the NEF network function may act as a relay for the SMF to communicate with the network function of the third party. When the NEF network functions as a relay, it can be used as a translation of the identification information of the subscriber and a translation of the identification information of the network element of the third party. For example, when NEF sends the SUPI of a subscriber from the carrier network to a third party, the SUPI may be translated into its corresponding external Identity (ID). Conversely, when NEF sends an external ID (an ID used in the third party's network) to the operator network, it can be translated into SUPI.

The PCF network function is a control plane function provided by the operator for providing the SMF with a policy for PDU sessions. The policies may include charging related policies, QoS related policies, authorization related policies, and the like.

Fig. 2 is an exemplary flow chart of a communication method in one embodiment of the present application. It should be understood that fig. 2 shows steps or operations of the method, but these steps or operations are only examples, and the technical solution proposed by the present application can also perform other operations or variations of the respective operations in fig. 2.

S210, the network equipment sends an RRC message or an NAS message to the terminal, wherein the RRC message or the NAS message contains Internet address information, the Internet address information is used for accessing relevant information of a first area, and the first area is a geographical area where the terminal is located.

Accordingly, the terminal receives the RRC message or the NAS message from the network device, so that the internet address information can be acquired from the RRC message or the NAS message.

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

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

In one possible implementation, the related information of the first area may include local information of the first area, such as a local talent introduction, convenience information, a detailed map, a restaurant, a merchant discount information, a community event information, a second-hand business information, and the like of the first area. The internet address information for accessing 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 resides in 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 can be understood that, when the terminal changes the serving cell, the serving access network device, or the serving AMF entity, the terminal may obtain new internet address information from the currently serving network device, that is, the internet address information may be updated along with the movement of the terminal, and does not need the participation of the user.

The information related to the first area may be stored in a server in the data network, which may be accessed through internet address information, so that the information related to the first area may be acquired.

Therefore, from the terminal perspective, no matter where the terminal moves, the user can conveniently and quickly acquire the relevant information of the local area (namely the first area) of the position where the terminal is located, the content server corresponding to the internet address information and providing the local information can provide comprehensive information, and can be used as a platform to gather scattered local information of various types, so that the information acquisition is 'extremely simple to the user' (namely the user can conveniently acquire the information), the popularization and the use are easy, and the information antenna can be extended to any place where the wireless signal can reach, including remote rural areas, mountain areas and the like, so that a real information society is constructed; it is naturally advantageous for the operator to provide portal addresses for local information through base stations located throughout the locality. By means of the unique resource, the method realizes differentiated competition with the internet service provider, and the internet manufacturer cannot follow the competition, so that the method has exclusivity and exclusivity. The method opens up a new blue sea for operators. In the business model, an operator can operate a content server providing local information by himself, for example, the content server can be handed to business halls of different levels to perform respective operation management, business returns are obtained through advertisements, video monthly payment, information distribution, electronic shop entrance and the like, the operator can also be rented to a third party to operate, for example, the third party is rented to a local government to operate, an entrance address is rented to make a profit, even some areas operate by himself, and other areas rent to other people to operate. The content server of the local information can provide comprehensive information, so that the user stickiness is improved. For local merchants/businesses/governments/property, etc.: the platform for releasing the information is provided, the efficiency is higher, the platform can be used as a further extension of the advertisement industry, and particularly, the platform for releasing the information is provided for medium and small merchants, and the local pertinence is higher. Compared with single-purpose mobile phone application software which provides services based on positions but provides information in a centralized mode, the information provided by the content server which provides local information and is linked with the internet address can be richer and more comprehensive, the information can be updated more timely through distributed maintenance, in addition, a Global Positioning System (GPS) does not need to be started, and even a mobile phone client program does not need to be installed, so that the mobile phone application software is more competitive.

When the network device is an access network device, the access network device may configure internet address information, so that when the terminal moves into the service range of the access network device, the access network device may send the internet address information to the terminal. Or, 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 sends the internet address information corresponding to the serving cell to the terminal according to the corresponding relationship.

When the network device is a core network device, the core network device may be configured with internet address information, so that when the terminal moves into the management range of the core network device, the core network device may send the internet address information to the terminal. Or, the core network device may be configured with a corresponding relationship between the internet address information and the access network device, so that when the terminal moves into a service range of which access network device, the core network device may send the internet address information corresponding to the access network device to the terminal according to the corresponding relationship. Or, 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 may send the internet address information corresponding to the serving cell to the terminal according to the corresponding relationship.

The areas related to the information that can be accessed by the internet address information corresponding to the multiple serving cells may be completely different, may also be completely the same, or may partially overlap. For example, the internet address information corresponding to different cells may all be relevant information for accessing the eastern region of pump. For another example, the internet address information corresponding to one serving cell may be used to access the relevant information of the golden bridge and the cloud mountain road, and the internet address information corresponding to another serving cell may be used to access the relevant information of the golden bridge and the new golden bridge.

The internet address information may be IP address information, general website information, or domain name address information. For example, one example of the internet address information is: com, http:// aabb.com, or http:// 201.12.101.10.

The information relating to the first area may comprise one or more of the following information: information in the first area, information in a second area adjacent to the first area, and information in a third area including the first area and the second area. This provides the terminal, i.e. the user, with more options and thus better fulfilled requirements.

For example, when the terminal is located in a Pudong area gold bridge in Shanghai, the first area may be a gold bridge, the second area may be a Mount road near the gold bridge, and the third area may be a Pudong area or Shanghai.

The information within any region may include one or more of the following information within the region: traffic information, weather information, geographic information, diet information, and the like.

The internet address information may include one or more internet addresses. When the internet address information includes a plurality of internet addresses, the plurality of internet addresses may correspond to the plurality of areas one by one, or may correspond to a plurality of types of information one by one.

When the plurality of internet addresses correspond to the plurality of areas one by one, in an implementation manner, the areas corresponding to the plurality of internet addresses respectively may be in an adjacent relationship, for example, an area corresponding to one internet address is a gold bridge road, and an area corresponding to another internet address is a cloud mountain road; in another implementation manner, the areas corresponding to the plurality of internet addresses may be in an inclusive relationship, for example, the area corresponding to one of the internet addresses is a golden bridge road, the area corresponding to another internet address is a eastern area, and even another area corresponding to one of the internet addresses is a Shanghai city; in another implementation, the areas corresponding to the internet addresses may include an adjacent relationship or an inclusion relationship. Alternatively, the plurality of internet addresses may correspond to a plurality of areas, and there may be an overlapping portion between the plurality of areas.

The plurality of internet addresses may 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 another of the internet addresses corresponds to traffic information in the first area.

The internet address information may further include a character string name corresponding to the address indicated by the internet address information. For example, http:// aabb.com and "gold bridge" may be included in the internet address information, or http:// ccdd.com and "Pudong area" may be included in the internet address information. Therefore, the user can more intuitively know what information corresponds to the address, and the requirements of the user can be better met.

The terminal, upon receiving the internet address information, may submit the internet address information to a higher layer (e.g., an operating system of the terminal), where the higher layer stores the internet address information or updates the previously stored internet address information. Or, after receiving the internet address information, the terminal may be stored by an Application Service (AS) layer or a non-access stratum (NAS) layer, and when a higher layer of the terminal needs to be used, the terminal transmits the internet address information to the higher layer.

S220, the terminal accesses the 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 (i.e., information of the first area), the user may link to a server providing information related to the first area through the internet address information, so as to obtain the information related to the first area.

For example, a portal or software may be provided on the operating system of the mobile phone, and after the user clicks the portal or software, the mobile phone may open the internet address information, thereby linking to the corresponding server.

For example, when the internet address is http:///aabb.com, after the user clicks the address, the mobile phone automatically opens the website by using a web browser. The opened web addresses may be different for terminals located in different cells. For example, the websites opened by the terminals located in different serving cells respectively correspond to the geographical areas covered by the serving cells in which the terminals are located. Of course, the internet address information received by the terminals corresponding to the multiple cells, the access network devices, or the core network devices may all be the same, may also be partially the same, or may be completely different. That is to say, the websites opened by the terminals served by different cells, access network devices, or core network devices may be the same or different, and this is not limited in this embodiment of the present application.

Alternatively, the terminal may integrate the internet address information received from the network device in the browser software, for example, as a web page in a bookmark or a favorite, the bookmark or web page being exemplified by local information or local treasure, and being linked to the internet address information. Alternatively, a link or icon on the desktop of the terminal (e.g., cell phone) may link to the internet address information.

When the user needs to access the local information, the bookmark, the webpage, the link or the icon is directly clicked, and the operating system of the terminal can directly open the corresponding internet address information, so that the local information is presented to the user.

After the terminal moves, or after the current serving cell or the resident cell is changed, the terminal can acquire the internet address information again, and then automatically update the bookmark, the webpage, the link or the icon into the internet address information.

In the communication method of the embodiment of the application, optionally, the network device may actively send the internet address information to the terminal, the terminal stores the internet address information after receiving the internet address information, and accesses the relevant information of the first area through the internet address information on the terminal when the user needs the internet address information.

Alternatively, the network device may transmit the internet address information to the terminal upon request of the terminal. As shown in fig. 3, in S310, the terminal sends request information to the network device to request internet address information corresponding to a first area to which the terminal belongs; after receiving the request message, the network device sends internet address information corresponding to the first area to the terminal in S320, and the terminal accesses related information of the first area based on the internet address information corresponding to the first area in S330. In fig. 3, S320 may refer to S210, and S330 may refer to S220, which are not described herein again.

When the network device actively sends the 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. And the terminal receives the system information of the service cell and acquires the Internet address information from the system information. The access network device may use a single System Information Block (SIB) to transmit the internet address information, and the terminal may read the SIB to obtain the internet address information.

When the network device actively sends the internet address information to the terminal, if the network device is an access network device, in other possible implementation manners, the access network device may send the internet address information to the terminal when the terminal enters an RRC connected state. For example, the access network device may send the internet address information to the terminal in an RRC connection setup message.

When the network device sends the internet address information to the terminal under the request of the terminal, if the network device is an access network device, the network device may send an on-demand (on-demand) SIB to the terminal under the request of the terminal, and send the internet address information to the terminal through the on-demand SIB. On-demand SIBs may also be referred to as other SIBs. Wireless resources may be saved by sending internet address information through the on-demand SIB.

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 an on-demand SIB including internet address information corresponding to the first area through the dedicated RACH preamble; after receiving the dedicated RACH preamble, the access network device may send an on-demand SIB to the terminal, where the on-demand SIB carries internet address information. After receiving the on-demand SIB, the terminal may acquire internet address information from the on-demand SIB.

When the network device sends internet address information to the terminal under the request of the terminal, if the network device is an access network device, in other possible implementation manners, after the terminal enters an RRC connection state, the terminal sends a dedicated RRC message to the access network device to request the access network device to send the internet address information, 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, the access network device replies a local address response RRC message to the terminal device, and the local address response RRC message carries the internet address information.

When the network device sends the internet address information to the terminal under the request of the terminal, if the network device is a core network device, the network device may send a NAS message under the request of the terminal, and send the internet address information to the terminal through the NAS message.

For example, the terminal may send request information to the core network device through the NAS message, to request internet information corresponding to the first area; and after receiving the NAS message, the core network equipment sends the NAS message to the terminal according to the request information in the NAS message, and the NAS message carries the Internet address information corresponding to the first area. For example, the terminal sends a local address request NAS message to the core network device, and the core network device replies a local address response NAS message to the terminal device, where the local address response NAS message carries internet address information.

In this embodiment, optionally, before the network device sends the internet address information to the terminal, the network device may send indication information to the terminal, to indicate that the network device supports providing internet address information for accessing the relevant information of the geographic area where the terminal is located, or to indicate that the network device can provide the internet address information, and the relevant information of the geographic area where the terminal is located may be accessed through the internet address information.

Further, optionally, as shown in S410 in fig. 4, the network device sends indication information to the terminal, indicating that it supports providing the internet address information. Correspondingly, in S420, the terminal may learn, according to the indication information, that the network device has the capability of providing address information of information related to the geographical area where the terminal is located, and send request information to the network device to request the internet address information; in S430, the network device sends the internet address information to the terminal according to the request of the terminal; in S440, the terminal accesses the related information of the geographic area to which it belongs based on the internet address information. The method shown in fig. 4 helps to avoid wasting resources. In fig. 4, S420 may refer to S310, S430 may refer to S210, and S440 may refer to S220, which is not described herein again.

When the network device is an access network device, in some possible implementations, the network device may send the indication 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 obtains the function that the access network equipment supports the internet address information corresponding to the geographical area where the terminal is located by reading the system information of the current serving cell (or the resident cell). After learning that the access network device has the function, the terminal can request internet address information from the access network device through RRC signaling. The terminal can immediately request the internet address information from the access network device, or the terminal device can request the internet address information from the access network device when the user needs the internet address information.

When the network device is a core network device, in some possible implementation manners, the network device may send indication information to the terminal in a registration process of the terminal, for example, in an initial registration or a mobility update registration process, so as to inform the terminal whether the network device supports providing the internet address information corresponding to the geographic area where the terminal is located for the terminal. For example, the network device may send the indication information to the terminal in a registration response message.

In the following, with reference to fig. 5, taking an access network device as a base station as an example, how a terminal obtains internet address information for accessing relevant information of a geographic area from the access network device in the present application is described.

For convenience of description, the internet address information for accessing the relevant information of the geographic area where the terminal is located is simply referred to as internet address information corresponding to the geographic area where the terminal is located.

S510, the base station broadcasts system information of a current service cell of the terminal, wherein the system information carries indication information, and the indication information is used for indicating that the cell supports a function of providing the terminal with internet address information corresponding to related information of a geographic area where the terminal is located. The terminal knows that the base station supports the function by reading the system information of the current serving cell (or camping cell).

S530, the terminal reads the system information and sends a request to the service base station after learning that the base station supports the function, so as to obtain the Internet address information corresponding to the geographic area where the terminal is located.

Optionally, if the terminal is in an idle (idle) state, S520 needs to be executed before S530, that is, the terminal needs to enter an RRC connection state first to send 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 the function, the terminal may not immediately send a request to the serving base station, but send a request to the serving base station when the user needs the internet address information corresponding to the geographical area where the user is located, so as to obtain the internet address information corresponding to the geographical area where the user is located.

Compared with the implementation mode that the terminal immediately sends the request to the service base station after knowing that the base station supports the function, the implementation mode that the user sends the request to the service base station only when needing the internet address information can save communication resources and save power consumption of the terminal. This is because the latter requires RRC connection regardless of whether the user needs internet address information, and the terminal in the idle state enters an RRC connected state to request internet address information from the base station, whereas the former requires the terminal in the idle state to perform an RRC connected state only when the user needs the internet address information.

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

S540, the base station sends RRC message carrying Internet address information to the terminal through the service cell.

In the following, with reference to fig. 6, taking core network equipment as an AMF entity as an example, how a terminal obtains internet address information for accessing relevant information of a geographic area where the terminal is located from the core network equipment in the present application is described.

Wherein, the AMF entity is called AMF for short. The internet address information used for accessing the relevant information of the geographic area where the terminal is located is simply referred to as 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), the terminal sends a registration request (registration request) message to the AMF to request registration. The step may refer to the existing terminal registration process, which is not described herein again.

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

And S640, after receiving the registration receiving message and knowing that the AMF supports the function, the terminal sends a request to the AMF to acquire the Internet address information corresponding to the geographic area.

Or, after receiving the registration receiving message and knowing that the base station supports the function, the terminal does not immediately send a request to the AMF, but sends a request to the AMF when the user needs the internet address information, so as to obtain the internet address information corresponding to the geographic area where the user is located. If the terminal is in an idle (idle) state, S630 needs to be performed before S640, that is, the terminal needs to enter an RRC connected state first to send a request to the AMF.

Compared with the implementation mode that the request is sent to the AMF immediately after the terminal learns that the AMF supports the function, the implementation mode that the user sends the request to the AMF only when the user needs the internet address information can save communication resources and save power consumption of the terminal. This is because the latter requires RRC connection regardless of whether the user needs internet address information, and the terminal in the idle state enters an RRC connected state to request internet address information from the AMF, whereas the former requires the terminal in the idle state to perform an RRC connected state only when the user needs internet address information.

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

And S650, after receiving the request of the terminal, the AMF determines the Internet address information corresponding to the geographic area where the terminal is located for the terminal.

Alternatively, the internet address information may be determined according to the address of the terminal. Further, the internet address information may 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 may carry indication information of the serving cell where the terminal is currently located, so that the AMF may determine the internet address information corresponding to the local information required by the terminal according to the serving cell of the terminal and the corresponding relationship.

S660, the AMF sends the NAS information carrying the Internet address information to the terminal.

In the communication method of the application, the network device is an access network device, and when 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 internet address of the local information of the second area adjacent to the first 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 may be actively obtained by the access network device from the adjacent access network device.

In some possible implementations, if the internet address corresponds to a serving cell, that is, the internet address is at a cell level, when an interface (e.g., Xn, X2, etc.) between base stations is established, two base stations may interact with the internet address corresponding to their respective cells. For example, a cell 1 and a cell 2 are located under the base station 1, a cell 3 and a cell 4 are located under the base station 2, when an interface between the base stations is established, the base station 1 sends internet addresses corresponding to the cell 1 and the cell 2 to the base station 2, and the base station 2 sends internet addresses corresponding to the cell 3 and the cell 4 to the base station 1.

In other possible implementation manners, if the internet address corresponds to the base station, that is, the internet address is at the base station level, when the two base stations establish an interface between the base stations, the base station 1 sends the internet address corresponding to the base station 1 to the base station 2, and the base station 2 sends the internet address corresponding to the base station 2 to the base station 1.

For example, as shown in fig. 7, in S710, the serving base station of the terminal transmits 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, where the response message carries the internet address corresponding to the neighboring base station; in S730, the serving base station sends internet address information to the terminal through the system information of the serving cell, where the internet address information includes an internet address corresponding to the serving base station and an internet address corresponding to an adjacent base station. S730 may refer to the related content in S210, and is not described herein again.

Or, in S720, the Xn interface setup 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 internet address information to the terminal through the system information of the serving cell, where the internet address information includes an internet address corresponding to the cell of the serving base station and an internet address corresponding to a cell of an adjacent base station.

In the communication method of the present application, optionally, the terminal may receive internet address information not only from a cell (serving cell) in which the terminal resides or from a serving access network device corresponding to the serving cell, but also from an adjacent cell or from an adjacent access network device. The internet address information from the serving cell or the serving access network device may be the same as or different from the internet address information from the neighboring cell or the neighboring access network device, where the same may be completely the same or partially the same.

For example, as shown in fig. 8, in S810, the terminal may receive system information from a serving base station (or a serving cell), acquire internet address information corresponding to the serving base station (or the 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 may receive system information from the neighboring base station (or the neighboring cell), acquire internet address information corresponding to the neighboring base station (or the neighboring cell) from the system information, and store the internet address information or update the internet address information on the terminal.

It should be noted that, although the foregoing embodiments all refer to how to transmit internet address information for accessing the relevant information of the first area to which the terminal belongs between the network device and the terminal, so that the terminal can access the relevant information of the first area according to the internet address information, the communication method provided by the present application may also be applied to transmit other address information that can access an external data network between the network device and the terminal. That is, it is not limited herein that the internet address information is only related information for accessing the first area.

That is, the above embodiments are simply adapted, for example, like that "the terminal receives internet address information from the network device, the internet address information is used for accessing the related information of the first area, and the first area is the geographic area where the terminal is located; the terminal accesses the related information of the first area based on the internet address information. "the terminal receives internet address information from the network device, the internet address information is used for accessing the related information of the data network, and the terminal accesses the related information of the data network based on the internet address information", for this simple adaptation, it is not listed here, but the solution after the simple adaptation is also within the protection scope of the embodiment of this application.
