In the following description, "some embodiments" are described, which describe a subset of all possible embodiments. However, it can be understood that "some embodiments" can be the same subset or different subset of all possible embodiments, and can be combined with each other without conflict.

[0033] In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the related technologies of the embodiments of the present application will be described below. The following related technologies can be combined with the technical solutions of the embodiments of the present application in any way, and all belong to the protection scope of the embodiments of the present application.

[0034] Currently, the data transmitted between BBUs is still in the point-to-point IP transmission protocol, such as the Xn interface between base stations. If the BBU needs to transmit data to other multiple BBUs at the same time, the BBU initiating the signal transmission needs to send to different BBUs for multiple times, even if the data sent is the same. This will cause waste of transmission network bandwidth. Especially when there is a requirement for sharing of base station BBU hardware resources, multiple BBUs multiplex the hardware capability of one BBU, and if the data bandwidth transmitted between BBUs is too large, it will affect the transmission bandwidth of normal communication services, resulting in a decrease in communication service quality.

[0035] Figure 1 is a schematic diagram of transmission of data between a BBU and a core network provided by an embodiment of the present application. As shown in Figure 1 , the BBU master multiplexes its capability to the BBU slave, so the service data of the BBU slave needs to be sent to the BBU master for processing, and the BBU slave can obtain control information to obtain optimization of service performance. The solid thin arrows in the figure represent the service data corresponding to each BBU issued by the core network, and each data service contains the IP address of the corresponding BBU and the next generation node B identity (GNB ID). Therefore, through the processing of the switching device, each BBU will obtain the service data issued to itself. When the service data of the BBU slave needs to use the hardware of the BBU master, on the one hand, the BBU slave itself issues the service data to the UE, and on the other hand, the BBU slave sends the service data to the BBU master, Figure 1 The dashed arrows in the figure represent the service data transmitted between base stations, and the BBU master processes the service data to obtain related control information for improving the service. The transmission mode still adopts the IP point-to-point mode, and the switching device sends the service data of each BBU slave to the BBU master. It can be seen that the service data (solid thin arrows and dashed arrows) is transmitted twice on the transmission link, which wastes the transmission bandwidth, and when the amount of service data is large, it may occupy the original communication service bandwidth. That is, the problem of the scheme is that the service data is transmitted twice on the transmission link, which wastes the transmission bandwidth, and when the amount of service data is large, it may occupy the original communication service bandwidth. The transmission delay is long twice, and the real-time performance of service optimization is difficult to guarantee. Therefore, the following technical scheme of the embodiment of the present application is proposed.

[0036] In order to facilitate understanding of the technical scheme of the present application, the technical scheme of the present application is described in detail through specific embodiments below. The above related technologies can be combined with the technical scheme of the present application as optional schemes, which all belong to the protection scope of the present application. The present application includes at least part of the following contents.

[0037] It should be noted that the master node described in the embodiments of the present application can be but is not limited to a BBU master, and the slave node described in the embodiments of the present application can be but is not limited to a BBU slave.

[0038] It should be noted that the core network described in the embodiments of the present application can be but is not limited to a 5G core network, an evolved or enhanced 5G core network, a 6G core network, etc.

[0039] It should be noted that the switch described in the embodiments of the present application can also be a switching device, that is, the switch and the switching device can be described by each other.

[0040] It should be noted that the unicast data described in the embodiments of the present application refers to service data transmitted in a unicast manner. The groupcast data described in the embodiments of the present application refers to service data transmitted in a groupcast manner.

[0041] Figure 2 is a flowchart of the information interaction method provided by the embodiments of the present application Figure 1 As shown in Figure 2 The information interaction method comprises the following steps:

[0042] Step 201: The first switch receives unicast data of a first slave node sent by a core network, encapsulates the unicast data of the first slave node into groupcast data, and the destination address of the groupcast data corresponds to the address of the first slave node and the address of a master node to which the first slave node belongs.

[0043] Here, the first switch can be a switch corresponding to a metropolitan access network.

[0044] Here, the first slave node is any one of N slave nodes, and N is a positive integer. Although the first slave node is described in the embodiments of the present application, the characteristics of any one of the N slave nodes can be referred to the description of the first slave node.

[0045] Step 201 specifically: the first switch receives unicast data of N slave nodes sent by a core network; for the unicast data of each slave node, the first switch encapsulates the unicast data of the node into groupcast data.

[0046] In some embodiments, the first slave node is described, and the first switch encapsulates the unicast data of the first slave node into groupcast data, which can be realized by the following way:

[0047] The first switch determines the address of the master node to which the first slave node belongs based on the first information, and determines the groupcast address based on the address of the first slave node and the address of the master node; based on the groupcast address, the unicast data of the first slave node is encapsulated into groupcast data, wherein the destination address of the groupcast data is the groupcast address.

[0048] Specifically, for the first slave node, the first switch determines the corresponding multicast address, which corresponds to the address of the first slave node and the address of the master node to which the first slave node belongs. The first switch adds a multicast header to the unicast data to obtain the multicast data. Here, the destination address in the multicast header is the multicast address. For the other slave nodes among the N slave nodes besides the first slave node, the same logic applies. For example, the multicast address corresponding to the data of slave node 1 includes the address of slave node 1 and the address of the master node to which slave node 1 belongs; the multicast address corresponding to the data of slave node 2 includes the address of slave node 2 and the address of the master node to which slave node 2 belongs; and so on, the multicast address corresponding to the data of slave node N includes the address of slave node N and the address of the master node to which slave node N belongs.

[0049] Step 202: The first switch sends the multicast data to the second switch, which then forwards the multicast data to the first slave node and the master node according to the destination address of the multicast data.

[0050] Here, the second switch can be the switch corresponding to the metropolitan area network access network. The second switch is used to forward data between the master node and N slave nodes.

[0051] Here, after the second switch receives the multicast data from the first slave node, since the destination address of the multicast data includes the address of the first slave node and the address of the master node to which the first slave node belongs, the second switch can forward the data to the first slave node based on the address of the first slave node, and can also forward the data to the master node based on the address of the master node.

[0052] Specifically, 1) For multicast data forwarded to the first slave node, the second switch removes the multicast header to obtain unicast data, and forwards the unicast data to the first slave node according to the destination address of the unicast data (i.e., the address of the first slave node). 2) For multicast data forwarded to the master node, the second switch directly forwards the multicast data to the master node according to the multicast address.

[0053] In some implementations, the method further includes: a first switch receiving unicast data from a master node sent by the core network, and sending the unicast data from the master node to a second switch, the second switch being used to forward the unicast data from the master node to the master node.

[0054] Here, the unicast data sent by the core network to the master node is sent through the first switch to the second switch, and then to the master node. In other words, the data of the master node is ultimately only sent to the master node.

[0055] In some implementations, the method further includes: a first switch acquiring first information, the first information including the address of a master node and the addresses of N slave nodes belonging to the master node, where N is a positive integer, and the first slave node is any one of the N slave nodes.

[0056] In some implementations, the base station network management system obtains the pairing relationship between the master node and the first slave node, obtains the IP address of the master node, and the IP addresses of the slave nodes connected to the master node. Then, the base station network management system informs the N slave nodes connected to the master node of their IP addresses. The base station network management system then informs the network management system of the switching device of this information, and the network management system of the switching device then informs the first switch of this information.

[0057] In the technical solution of this application embodiment, a first switch receives unicast data from a first slave node sent by the core network, encapsulates the unicast data into multicast data, and the destination address of the multicast data corresponds to the address of the first slave node and the address of the master node to which the first slave node belongs. The first switch sends the multicast data to a second switch, which forwards the multicast data to the first slave node and the master node according to the destination address of the multicast data. In this way, data sent by the core network to the first slave node can be simultaneously sent to the first slave node and the corresponding master node through multicast. The first slave node does not need to send the data to the master node again, thereby reducing the bandwidth of service data transmission between nodes in the downlink direction and reducing the latency of service data transmission between nodes.

[0058] Figure 3 This is a flowchart illustrating the information interaction method provided in the embodiments of this application. Figure 2 ,like Figure 3 As shown, the information interaction method includes the following steps:

[0059] Step 301: The second switch receives the unicast data sent by the first slave node, encapsulates the unicast data of the first slave node into multicast data, and the destination address of the multicast data corresponds to the address of the core network and the address of the master node to which the first slave node belongs.

[0060] Here, the second switch can be the switch corresponding to the metropolitan area access network.

[0061] Here, the first slave node is any one of the N slave nodes, where N is a positive integer. Although this embodiment is described using the first slave node, the characteristics of any one of the N slave nodes can be referred to the description of the first slave node.

[0062] Step 301 specifically involves the second switch receiving unicast data from each of the N slave nodes; for each slave node's unicast data, the second switch encapsulates the node's unicast data into multicast data.

[0063] In some embodiments, the first slave node is taken as an example, the second switch encapsulates the unicast data of the first slave node into multicast data, which can be achieved in the following way:

[0064] The second switch determines the address of the master node to which the first slave node belongs based on the first information, and determines the multicast address based on the address of the core network and the address of the master node; and encapsulates the unicast data of the first slave node into multicast data based on the multicast address, where the destination address of the multicast data is the multicast address.

[0065] Specifically, for the first slave node, the second switch determines the corresponding multicast address, which corresponds to the address of the master node to which the first slave node belongs and the address of the core network to which the first slave node is finally connected; and adds a multicast packet header based on the unicast data, thereby obtaining the multicast data, where the destination address in the multicast packet header is the multicast address. For other slave nodes except the first slave node in the N slave nodes, the same as the first slave node, for example: the multicast address corresponding to the data of the slave node 1 includes the address of the master node to which the slave node 1 belongs and the address of the core network to which the slave node 1 is finally connected; the multicast address corresponding to the data of the slave node 2 includes the address of the master node to which the slave node 2 belongs and the address of the core network to which the slave node 2 is finally connected; and so on, the multicast address corresponding to the data of the slave node N includes the address of the master node to which the slave node N belongs and the address of the core network to which the slave node N is finally connected.

[0066] Step 302: The second switch forwards the multicast data to the first switch and the master node according to the destination address of the multicast data, and the first switch is used to decapsulate the multicast data into the unicast data of the first slave node and then forwards the unicast data to the core network.

[0067] Here, the first switch can be the switch corresponding to the metropolitan access network. The first switch is used to forward the data of the master node and the N slave nodes to the core network.

[0068] Here, since the destination address of the multicast data includes the address of the master node to which the first slave node belongs and the address of the core network to which the first slave node is finally connected, the second switch forwards the multicast data of the first slave node to the master node to which the first slave node belongs according to the address of the master node, or forwards the data to the first switch according to the address of the core network. After receiving the multicast data of the first slave node, the first switch decapsulates the multicast data into the unicast data of the first slave node according to the address of the core network to which the first slave node is finally connected, and then forwards the unicast data to the core network.

[0069] Specifically, 1) for the multicast data forwarded to the first switch, the first switch removes the multicast header of the multicast data to obtain unicast data, and forwards the unicast data to the core network according to the destination address of the unicast data (i.e. the address of the core network to which the first slave node is finally connected); 2) for the multicast data forwarded to the master node, the second switch directly forwards the multicast data to the master node according to the multicast address.

[0070] In some embodiments, the method further comprises: the second switch receiving unicast data sent by the master node, and forwarding the unicast data sent by the master node to the first switch, and the first switch being configured to forward the unicast data of the master node to the core network.

[0071] Here, the unicast data sent by the master node is sent to the first switch through the second switch, and then to the core network, that is, the data of the master node is only sent to the core network.

[0072] In some embodiments, the method further comprises: the second switch obtaining first information, the first information comprising the address of the master node and the addresses of N slave nodes subordinate to the master node, N being a positive integer, wherein the first slave node is any one of the N slave nodes.

[0073] In some embodiments, the base station gateway obtains the pairing relationship of the master node and the slave nodes, the IP address of the master node, the IP addresses of N slave nodes subordinate to the master node, and the IP address of the core network to which the master node and the slave nodes are finally connected. Then, the base station gateway informs the master node of the IP addresses of the slave nodes subordinate to the master node. The base station gateway informs the network management device of the switch equipment of the above information, and the network management device of the switch equipment informs the second switch of the information.

[0074] The technical scheme of the embodiments of the present application, the second switch receives unicast data sent by the first slave node, encapsulates the unicast data of the first slave node into multicast data, the destination address of the multicast data corresponding to the address of the core network and the address of the master node to which the first slave node is subordinate; the second switch forwards the multicast data to the first switch and the master node according to the destination address of the multicast data, and the first switch is configured to forward the multicast data to the core network after decapsulating the multicast data into the unicast data of the first slave node. In this way, the data sent by the first slave node to the second switch can be simultaneously sent to the master node and the core network through the multicast mode, and the first slave node does not need to send the data to the master node again, thereby reducing the bandwidth of the transmission of service data between nodes in the uplink direction and the time delay of the transmission of service data between nodes.

[0075] The technical scheme of the embodiments of the present application is illustrated below in conjunction with specific application examples.

[0076] Based on the foregoing embodiments, a scheme for information interaction between base stations is proposed to reduce the occupation of transmission bandwidth and optimize the delay. The core purpose of the present application is to change the way of transmitting information between BBU and core network, so that the original point-to-point transmission between BBU and core network is changed to multi-point-to-point transmission between BBU and core network, so as to reduce the bandwidth and delay. In the downlink direction: the data sent by the core network to the BBU master and the BBU slave is sent to the BBU master at a time. In the uplink direction: the data sent by the UE on the BBU slave to the core network is sent to the BBU master at a time. Based on this, the information interaction method provided by the embodiments of the present application is further described. The specific implementation scheme is as follows:

[0077] I) Downlink direction

[0078] Figure 4 is the downlink service data processing flowchart provided by the embodiments of the present application; as shown in Figure 4 , the 5G core network (5G Core, 5GC) device sends the service data of the BBU master and the BBU slave to the switch 1 (equivalent to the first switch in the foregoing embodiments), and the switch 1 sends the data of each BBU slave to each BBU slave, and sends the service data of the BBU slave and the service data of the BBU master to the BBU master. The specific description is as follows:

[0079] 1) The base station network management obtains the pairing relationship of the BBU master and the BBU slave, and the following information: IP address of the BBU master; IP address of the BBU slave under the BBU master.

[0080] 2) The base station network management informs the BBU master of the IP address of the BBU slave under it, and in addition, the base station network management informs the network management of the switch device of the above information.

[0081] 3) In the downlink direction, the BBU master and the BBU slave under it are divided into a group.

[0082] 4) After the switch 1 parses the service data of the BBU slave, the service data of the BBU slave is packaged according to the multicast mode, and the multicast destination address includes the address of the BBU slave and the address of the BBU master to which it belongs.

[0083] 5) Through the multicast mode, the service data of the BBU master and the BBU slave under it all reach the switch 2 (equivalent to the second switch in the foregoing embodiments).

[0084] 6) For the service data of BBU slaves under switch 2, the switch removes the multicast packet header and restores the unicast format. According to the IP address of each BBU slave, the switch sends the data of each BBU slave to the corresponding BBU slave. For the BBU master, switch 2 still sends all the service data of the BBU master and the service data of the BBU slaves to the BBU master. The BBU master receives its own and the service data of the BBU slaves through the obtained IP address of the BBU slave.

[0085] (ii) Upward direction

[0086] Figure 5 This is a schematic diagram of the uplink business data processing flow provided in the embodiments of this application; as shown below. Figure 5 As shown, the service data of the BBU master and BBU slave are sent to switch 2 (equivalent to the second switch in the aforementioned embodiment). Switch 2 sends the data from the BBU slave to the BBU master and the core network, and switch 2 sends the data from the BBU master to the core network. Specific details are as follows:

[0087] 1) The base station network management obtains the pairing relationship between the BBU master and BBU slave, as well as the following information: the IP address of the BBU master, the IP address of the BBU slave connected to the BBU master, and the IP address of the core network to which the BBU master and BBU slave are ultimately connected.

[0088] 2) The base station network management system informs the BBU master of the IP addresses of its BBU slaves. In addition, the base station network management system informs the network management system of the switch equipment of the above information.

[0089] 3) In the uplink direction, the BBU main network and core network are divided into a group.

[0090] 4) After parsing the uplink service data from the BBU slave, switch 2 adds the corresponding packet header to the BBU slave's service data in a multicast manner. The multicast destination address includes the address of the BBU master and the address of the core network.

[0091] 5) Through multicast, the BBU master receives the uplink data from its BBU slaves, and switch 1 also receives the service data from the BBU slaves.

[0092] 6) After parsing the multicast service data of the BBU slave, switch 1 (equivalent to the first switch in the above embodiment) removes the multicast packet header and multicast IP address from the service data of the BBU slave, changes it to unicast mode, and transmits the uplink signal of the BBU slave to the core network.

[0093] The technical scheme of the embodiment of the application realizes the interaction of information between BBUs in a multicast manner. The BBU network management obtains the subordinate relationship and IP address between BBUs, and informs the switch network management. After identifying the service of the BBU slave, the switch obtains the subordinate relationship and IP address between BBUs, and realizes the multicast between BBUs. The switch can also realize the unicast between the BBU service and the core network by removing the multicast packet header of the BBU. In this way, the application reduces the bandwidth consumed by the transmission of service data between BBUs, and reduces the time delay of the transmission of service data between BBUs.
