Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method and apparatus. Background Technology

[0002] In the current telecommunications field, due to the high cost of independently building networks, multiple operators typically share network resources. Network resources include network infrastructure, network equipment, and spectrum resources. Infrastructure includes facilities such as data centers, sites, power supply equipment, and towers, while network equipment includes base stations and core network equipment. Two base stations exchange signaling information via the Xn Application Protocol (XnAP) interface. An XnAP channel established through this interface includes the Public Land Mobile Network (PLMN), base station ID, base station ID length, Internet Protocol (IP) address, and port number. However, because different operators have different PLMNs and base station IDs, a single XnAP channel cannot support data interoperability between two different operators.

[0003] In related technologies, if two base stations support data interoperability between multiple operators, it is generally necessary to establish multiple XnAP channels, which in turn requires the establishment of multiple Stream Control Transmission Protocol (SCTP) connections. This results in high connection maintenance costs and excessive equipment resource consumption. Summary of the Invention

[0004] This application provides a communication method and apparatus to solve the problem of wasted IP address and port number resources caused by base stations transmitting data from different providers through different communication connections.

[0005] Firstly, this application proposes a communication method, including:

[0006] The target operator to which the data to be sent belongs is determined, and the second base station indicated by the destination address of the data to be sent is determined; the communication connection between the first base station and the second base station is associated with multiple Xn Application Protocol (XnAP) channels; wherein, the multiple XnAP channels are used to transmit data from different operators;

[0007] Determine the target XnAP channel corresponding to the target operator from the plurality of XnAP channels;

[0018] Receive response information returned by the second base station; the response information is used to indicate that the communication connection and the backup communication connection have been successfully established.

[0019] In some embodiments, the target XnAP channel is established in the following manner:

[0020] When it is determined that the target XnAP channel is not included among the plurality of XnAP channels, a request is made to the second base station through the communication connection to establish the target XnAP channel;

[0021] Based on the request response returned by the second base station, it is determined that the target XnAP channel has been successfully established with the second base station, and the association between the target XnAP channel and the communication connection is recorded.

[0022] In some embodiments, the method further includes:

[0023] When the number of XnAP channels associated with the communication connection is determined to be zero, the communication connection is deleted. Secondly, this application proposes a communication apparatus, which is applied to a first base station, or the apparatus is a first base station, the apparatus comprising:

[0024] The processing unit is configured to determine the target operator to which the data to be sent belongs, and to determine the second base station indicated by the destination address of the data to be sent; the communication connection between the first base station and the second base station is associated with multiple Xn Application Protocol (XnAP) channels; wherein, the multiple XnAP channels are used to transmit data from different operators;

[0025] The processing unit is further configured to determine, from the plurality of XnAP channels, a target XnAP channel corresponding to the target operator;

[0026] A communication unit is used to send the data to be sent to the second base station through the target XnAP channel.

[0027] In some embodiments, after determining the target XnAP channel corresponding to the target operator, the method further includes:

[0028] Obtain the identifier of the target operator corresponding to the stored target XnAP channel;

[0029] The data to be sent is encapsulated using the identifier of the target operator;

[0030] When the communication unit sends the data to be sent to the second base station through the target XnAP channel, it is specifically used for:

[0031] The encapsulated data to be transmitted is sent to the second base station.

[0032] In some embodiments, a backup communication connection is further included between the first base station and the second base station; when it is determined that the communication connection is disconnected, the communication unit communicates with the second base station through the backup communication connection.

[0033] In some embodiments, the communication unit is further configured to:

[0034] When it is determined that the destination address of the data to be sent indicates the second base station, and no communication connection with the second base station is found, a communication request is sent to the second base station; the communication request is used to request the second base station to establish the communication connection and a backup communication connection;

[0035] Receive response information returned by the second base station; the response information is used to indicate that the communication connection and the backup communication connection have been successfully established.

[0037] The processing unit is further configured to determine, based on the request response returned by the second base station, that the target XnAP channel has been successfully established with the second base station, and to record the association between the target XnAP channel and the communication connection.

[0038] In some embodiments, the processing unit is further configured to:

[0042] Based on the above scheme, this application proposes establishing a communication connection when transmitting data between any two base stations, and establishing corresponding XnAP channels for different operators based on this communication connection. Data from different operators can be transmitted through different XnAP channels, thereby enabling the transmission of data from multiple operators between two base stations through a single communication connection. Compared to the prior art of transmitting data from different operators through multiple communication connections, the scheme of this application effectively saves IP address and port number resources. Furthermore, independently managing and maintaining the XnAP channel corresponding to each operator also avoids the problem of high complexity in maintaining a single XnAP channel.

Additionally, the character " / " in this article, unless otherwise specified, generally indicates that the preceding and following related objects have an "or" relationship.

[0052] To facilitate understanding of the proposed solution, the technical background of this application will be introduced first. See [link to relevant documentation]. Figure 1 This is an architecture diagram of a communication system provided in an embodiment of this application. It should be understood that the embodiments of this application are not limited to... Figure 1 The system shown. For example... Figure 1 As shown, the system architecture provided in this application embodiment includes a terminal and a base station. It should be noted that... Figure 1This application does not limit the number of terminals and base stations included in the communication system, but only as an example. For ease of description, Figure 1 The example shows two terminals and two base stations. Additionally, the communication system may also include core network equipment. Figure 1 Not shown in the image. For example, Figure 1 The core network equipment not shown may include the Access and Mobility Management Function (AMF), the Session Management Function (SMF), etc.

[0053] User equipment (UE), also known as terminal equipment, mobile station (MS), or mobile terminal (MT), is a device that provides voice and / or data connectivity to users. Examples include handheld devices with wireless connectivity and in-vehicle devices. Currently, some examples of terminals include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, and wireless terminals in smart homes.

[0054] The first and second base stations involved in this application embodiment are public mobile communication base stations, which are interface devices for mobile terminals to access the Internet. Figure 1The base station shown may be an evolved Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, or a Next Generation Node B (gNB) in a 5G mobile communication system; this application does not limit it to either.

[0055] During the communication process between the first base station and the second base station, a communication connection needs to be established between them first to transmit data. Optionally, when establishing the communication connection, the first and second base stations can obtain each other's port numbers and define the transport layer protocol used for data transmission through information exchange. Then, when transmitting data through the communication connection, the data can be encapsulated using the obtained port number of the other base station and the defined transport layer protocol, and the encapsulated data can be sent to the other base station.

[0056] Furthermore, in the field of communications, due to the high costs of spectrum licenses and network deployment faced by operators building their own networks independently, the concept of multi-operator network sharing has been proposed in current communication systems, such as 5G mobile communication systems. Multi-operator sharing refers to any degree of cooperation or sharing of network infrastructure, network equipment, and spectrum resources among multiple operators (or third-party suppliers), such as multiple operators jointly building base stations, core networks, and other network equipment. For example, if the aforementioned first and second base stations are shared by multiple operators, then data from these multiple operators can be transmitted between the first and second base stations. When transmitting data from different operators, the first and second base stations need to transmit through different XnAP channels. Therefore, before transmitting data, the first and second base stations need to establish an XnAP channel between them to transmit data from different operators. For example, when establishing an XnAP channel between the first and second base stations for any operator, the two base stations can obtain data such as the base station ID, base station ID length, and PLMN for that operator's peer base station through information exchange, and define the application layer protocol used for data transmission, such as Hypertext Transfer Protocol (HTTP). Therefore, when transmitting data from either operator between the first base station and the second base station, the acquired data and the negotiated protocol can be used to encapsulate the data to be transmitted before sending it to the other base station.

[0057] An XnAP channel includes a PLMN, base station ID, base station ID length, IP address, and port number. However, different operators have different PLMNs and base station IDs; for example, the base station IDs of the first base station are different for operators A and B. Therefore, an XnAP channel established between two base stations cannot support data interoperability between more than two different operators. Therefore, two solutions have been proposed in related technologies:

[0058] Option 1: Solve the multi-carrier data interoperability problem by establishing multiple XnAP channels between the two base stations. For example, using... Figure 1 Taking the first base station and the second base station shown as examples, the first base station is set to support the transmission of data from operator A and operator B, and the second base station also supports the transmission of data from operator A and operator B. Therefore, when establishing the XnAP channel between the first base station and the second base station, two XnAP channels need to be established, namely: operator A of the first base station → operator A of the second base station, and operator B of the first base station → operator B of the second base station.

[0059] However, while Scheme 1 can solve the problem of multi-carrier data interoperability between two base stations, it requires establishing SCTP connections for each of the multiple established XnAP channels. Each SCTP connection requires an IP address and port number, resulting in resource issues related to IP addresses and port numbers, as well as high maintenance costs for the base stations, consuming their processing and memory resources. Therefore, this application proposes that after establishing an SCTP connection between the first and second base stations, different XnAP channels are established for different carriers, and the association between the established XnAP channels and the SCTP connection is recorded. This allows data from different carriers to be transmitted through different XnAP channels. Compared to Scheme 1, this application's scheme does not require establishing multiple SCTP channels; instead, it establishes multiple XnAP channels based on a single SCTP channel, thus solving the problem of wasted IP address and port number resources.

[0060] Option 2: Support data from multiple operators simultaneously through a single XnAP channel. Option 2, using a single XnAP channel, increases the complexity of the XnAP data logic and makes maintenance more complicated. It also requires secondary analysis of transmitted packets to determine which operator they belong to. Furthermore, some XnAP channels currently cannot distinguish between operators, thus failing to prevent data interoperability issues between base stations from different operators. Therefore, this application proposes establishing different XnAP channels for different operators, allowing data from different operators to be transmitted through different XnAP channels. Compared to Option 2, this application's solution establishes multiple XnAP channels based on the number of operators, independently managing and maintaining each XnAP channel, thus avoiding the high complexity of maintaining a single XnAP channel in Option 2.

[0061] Below, in conjunction with Figure 1 The communication system shown illustrates the communication method proposed in this application. See also... Figure 2 This is a flowchart of a communication method provided in an embodiment of this application. Optionally, the method flowchart can be... Figure 1 The system shown is executed by either a first base station or a second base station. For ease of description, in Figure 2 The lieutenant general will use the first base station as an example to illustrate the process. Figure 2 The method flow shown specifically includes:

[0062] 201. The first base station determines the target operator to which the data to be sent belongs, and determines the second base station indicated by the destination address of the data to be sent.

[0063] Optionally, the data to be sent may be data forwarded by the first base station, and the first base station can determine the destination address and the operator to which the data belongs based on the header of the data to be sent.

[0064] 202, the first base station queries the target XnAP channel corresponding to the target operator from multiple XnAP channels associated with the communication connection between the first base station and the second base station.

[0065] The multiple XnAP channels associated with the communication connection correspond to different operators and are used to transmit data from different operators.

[0066] Optionally, the communication connection can be established when the first base station and the second base station first transmit data. Based on this communication connection, XnAP channels corresponding to different operators are established, and the communication connection and the association between multiple XnAP channels are recorded. For example, multiple XnAP channels associated with the communication connection to the second base station can be stored in a table. Different XnAP channels are used to transmit data from different operators, and different operator identifiers (such as the ID of the second base station, the ID length of the second base station, and the PLMN of the second base station) can be used to distinguish different XnAP channels. It should be noted that the ID of the second base station, the ID length of the second base station, and the PLMN of the second base station are different for different operators. Therefore, this application proposes to use operator identifiers to distinguish different operator XnAP channels when recording XnAP channels of different operators.

[0067] After determining the target operator to which the data to be transmitted belongs, the first base station can query the target XnAP channel corresponding to the target operator from multiple XnAP channels associated with the recorded communication connection. In one possible query method, when storing the multiple XnAP channels associated with the communication connection between the first base station and the second base station, the first base station can also mark the name of the operator corresponding to each XnAP channel. When querying the XnAP channel of the target operator, the query can be performed by name. In another possible query method, since the PLMNs corresponding to different operators are publicly known, the first base station can query based on the PLMN included in the stored operator identifiers.

[0068] 203. The first base station sends the data to be sent to the second base station through the target XnAP channel.

[0069] In one possible implementation, after the first base station locates the target XnAP channel, it can obtain the identifier of the target operator corresponding to the target XnAP channel from the storage, such as the PLMN, base station ID, and base station ID length of the second base station for the target operator. The first base station can encapsulate the data to be transmitted based on the obtained identifier of the target operator, and send the encapsulated data to the second base station through a pre-established communication connection with the second base station.

[0070] Based on the above scheme, this application proposes establishing a single communication connection when transmitting data between any two base stations. Based on this communication connection, corresponding XnAP channels are established for different operators. Data from different operators can be transmitted through different XnAP channels, thus enabling the transmission of data from multiple operators between two base stations via a single communication connection. Compared to the prior art of transmitting data through multiple communication connections, this application's scheme effectively saves IP address and port number resources. Furthermore, independently managing and maintaining the XnAP channel corresponding to each operator avoids the difficulty of maintaining a single XnAP channel.

[0071] In one possible scenario, if the first base station fails to find the target XnAP channel among multiple XnAP channels during step 202, it can request the establishment of the target XnAP channel from the second base station via the communication connection and record the association between the successfully established target XnAP channel and the communication connection. The process of establishing a target XnAP channel between the first and second base stations is described below:

[0072] Optionally, when requesting to establish a target XnAP channel, the first base station may send a channel establishment request to the second base station, which may carry the identifier of the target operator corresponding to the first base station, such as the PLMN, base station ID, and base station ID length for the first base station of the target operator. After receiving the channel establishment request, the second base station may return a request response to the first base station. The request response indicates that the target XnAP channel has been successfully established with the first base station, and the request response carries the identifier of the target operator corresponding to the second base station, such as the PLMN, base station ID, and base station ID length for the second base station of the target operator. After receiving the request response, the first base station can determine that the target XnAP channel with the second base station has been successfully established. Optionally, the first base station may store the identifier of the target operator corresponding to the second base station and record the association between the target XnAP channel and the communication connection.

[0073] After successfully establishing the target XnAP channel, data from the target operator can be transmitted to the second base station via the target XnAP channel. For example, the first base station can encapsulate the data using the identifier of the target operator corresponding to the target XnAP channel, and then send the encapsulated data to the second base station through the communication connection between the first and second base stations.

[0074] The process of establishing a communication connection between the first base station and the second base station is described below. Optionally, the first base station may send a communication request to the second base station if it determines that the destination address of the data to be transmitted indicates the second base station and no communication connection with the second base station is found. This communication request is used to request the establishment of a communication connection with the second base station. After receiving the communication request, the second base station may return response information to the first base station, indicating that the communication connection between the first and second base stations has been successfully established.

[0075] Optionally, a backup communication connection can also be established between the first base station and the second base station for use when the communication connection is lost. The method for creating the backup communication connection is described in the above-described communication connection creation process and will not be repeated here. After the communication connection between the first base station and the second base station is successfully established, multiple XnAP channels corresponding to different operators can be established based on this communication connection, and the association between the established XnAP channels and the communication connection is recorded. The specific process for establishing XnAP channels based on the communication connection is described in the above embodiments and will not be repeated here. In some embodiments, if a backup communication connection exists, when establishing an XnAP channel for a certain operator based on the communication connection, an XnAP channel for that operator can also be established based on the backup communication connection, and the association between the established XnAP channel and the backup communication connection is recorded. Similarly, if communication is performed using the communication connection, multiple XnAP channels associated with the communication connection can be queried, and one can be selected for data transmission. If communication is performed using the backup communication connection, multiple XnAP channels associated with the backup communication connection can be queried, and one can be selected for data transmission.

[0076] In some embodiments, to maintain and manage the XnAP channel, the first base station and the second base station may periodically transmit keep-alive messages through the XnAP channel. When the first base station determines that the keep-alive message transmission is abnormal, for example, if it has not received a keep-alive message from the second base station within a set number of periods, it can set the corresponding XnAP channel to a disconnected state. In some possible cases, such as when the first base station and the second base station no longer need to transmit data from the target operator, the XnAP channel corresponding to the target operator that is set to a disconnected state can be deleted.

[0077] Optionally, the first base station may also acquire recorded XnAP channels that are associated with the communication connection of the second base station. When it is determined that the number of acquired XnAP channels is zero, that is, when all XnAP channels established based on the communication connection are deleted, the communication connection with the second base station is deleted.

[0078] The following describes the process of establishing communication connections between base stations, establishing XnAP channels, and transmitting data, using specific embodiments as examples. Continuing with the example of the first and second base stations, see [link to relevant documentation]. Figure 3 Here is a flowchart of a communication method proposed in an embodiment of this application, which specifically includes:

[0079] 301, The first base station determines the second base station indicated by the destination address of the data to be sent.

[0080] 302. When the first base station determines that there is no communication connection between it and the second base station, it sends a communication request to the second base station.

[0081] The communication request is used to request the establishment of a communication connection with the second base station.

[0082] 303, The second base station receives the communication request and returns response information to the first base station.

[0083] The response information indicates that the communication connection between the first base station and the second base station has been successfully established.

[0084] 304. The first base station receives the response information and determines the operator A to which the data to be sent belongs.

[0085] 305. The first base station sends a channel request to the second base station through the communication connection.

[0086] The channel request is used to request the establishment of an XnAP channel corresponding to operator A, and the channel request carries the identifier of operator A corresponding to the first base station.

[0087] 306, The second base station receives the channel request and returns a request response to the first base station.

[0088] The request response is used to indicate that the XnAP channel for transmitting data of operator A between the first base station and the second base station has been successfully established, and the request response carries the identifier of operator A corresponding to the second base station.

[0089] Optionally, the second base station may also store the identifier of operator A corresponding to the first base station carried in the channel request, for subsequent transmission of operator A data with the first base station.

[0090] 307. The first base station receives the request response, encapsulates the data to be sent using the identifier of operator A corresponding to the second base station, and sends the encapsulated data to the second base station.

[0091] Based on the same concept as the method described above, see [link to relevant documentation]. Figure 4This application provides a communication device 400 for implementing the various steps in the above method. To avoid repetition, these steps will not be described again here. The device 400 includes a processing unit 401 and a communication unit 402.

[0097] The data to be sent is encapsulated using the identifier of the target operator;

[0098] When the communication unit 402 sends the data to be sent to the second base station through the target XnAP channel, it is specifically used for:

[0099] The encapsulated data to be transmitted is sent to the second base station.
