Description

Technical Field

[0001] This application belongs to the field of communication technology, and in particular relates to a communication method, device, storage medium, program product and converged gateway system. Background Technology

[0002] Because wireless networks can be obstructed by building structures, there may be areas indoors where mobile devices cannot access the wireless network, known as blind spots. Small base stations can be deployed in these blind spots to supplement wireless network coverage.

[0003] To ensure that small base stations can achieve their signal coverage function, related technologies can connect small base stations to optical modems, thereby ensuring that small base stations can connect to the core network and guarantee their signal coverage function.

[0004] However, when transmitting communication signals through an optical modem, it is impossible to prioritize the communication signals between the base station and the core network, which leads to signal delays and even communication interruptions. Summary of the Invention

[0005] This application provides a communication method, device, storage medium, program product, and converged gateway system that can achieve priority forwarding of message data between the base station and the core network.

[0006] In a first aspect, embodiments of this application provide a communication method applied to a converged gateway system. The converged gateway system includes an optical modem module and a base station module. The optical modem module includes a first communication interface connected to an optical line terminal equipment and a second communication interface connected to the base station module. The method includes: in response to receiving message data sent by the first communication interface or the second communication interface, determining the address identifier of the message data; if the address identifier of the message data matches any preset address identifier stored in a preset address identifier list, storing the message data in a priority forwarding queue; and forwarding the message data according to the storage order of the message data in the priority forwarding queue.

[0007] In one embodiment, the method further includes: if it is determined that the address identifier of the message data does not match any of the preset address identifiers stored in the preset address identifier list, storing the message data in a non-priority forwarding queue; if it is determined that the priority forwarding queue is an empty queue, forwarding the message data according to the storage order of the message data in the non-priority forwarding queue.

[0008] In one implementation, the message data includes downlink message data received from the first communication interface;

[0009] If the address identifier of the message data matches any of the preset address identifiers stored in the preset address identifier list, the message data is stored in the priority forwarding queue, including: if the source address identifier of the downlink message data matches any of the preset address identifiers stored in the preset address identifier list, the downlink message data is stored in the downlink priority forwarding queue; the message data is forwarded according to the storage order of the message data in the priority forwarding queue, including: forwarding the downlink message data in the downlink priority forwarding queue through the second communication interface according to the storage order of the message data in the downlink priority forwarding queue.

[0010] In one implementation, the message data includes uplink message data received from the second communication interface;

[0011] If the address identifier of the message data matches any of the preset address identifiers stored in the preset address identifier list, the message data is stored in the priority forwarding queue, including: if the destination address identifier of the uplink message data matches any of the preset address identifiers stored in the preset address identifier list, the uplink message data is stored in the uplink priority forwarding queue; and the message data is forwarded according to the priority forwarding queue, including: forwarding the uplink message data in the uplink priority forwarding queue through the first communication interface according to the storage order of the message data in the uplink priority forwarding queue.

[0012] In one embodiment, before storing the message data in the priority forwarding queue when it is determined that the address identifier of the message data matches any preset address identifier stored in the preset address identifier list, the method further includes: obtaining the preset address identifier list through the base station module.

[0013] In one implementation, obtaining a preset address identifier list through a base station module includes: obtaining the preset address identifiers after address changes through the base station module.

[0014] In one embodiment, forwarding message data according to the storage order of message data in the priority forwarding queue includes: when it is determined that the data forwarding interface corresponding to the message data is in an idle state, forwarding the message data according to the storage order of message data in the priority forwarding queue; or, when it is determined that the data forwarding interface corresponding to the message data is in a message forwarding state, after forwarding the current message data, forwarding the message data according to the storage order of message data in the priority forwarding queue; wherein the data forwarding interface corresponding to the message data is a first communication interface or a second communication interface.

[0015] Secondly, embodiments of this application provide a converged gateway system, including: an optical modem module, used to implement the communication method in the first aspect or any one of the embodiments of the first aspect, the optical modem module including a first communication interface and a second communication interface, the first communication interface being used to transmit message data with an optical line terminal device;

[0016] The base station module is connected to the second communication interface of the optical modem module. The base station module is used to transmit message data with the optical modem module.

[0017] In one embodiment, the system further includes a power supply that supplies power to the optical modem module and the base station module.

[0018] Thirdly, embodiments of this application provide a communication device, the device comprising:

[0019] The determination module is used to determine the address identifier of the message data in response to receiving message data sent by the first communication interface or the second communication interface;

[0020] The storage module is used to store the message data in the priority forwarding queue when the address identifier of the message data matches any of the preset address identifiers stored in the preset address identifier list.

[0025] The communication method, device, storage medium, program product, and converged gateway system of this application determine whether the message data received by the optical modem module is a communication signal between the base station and the core network by judging the address identifier of the message data. If so, the message data is stored in a priority forwarding queue to achieve priority forwarding of the message data. This ensures that the message data between the base station and the core network can be preferentially allocated the data transmission bandwidth of the base station backhaul channel, thereby ensuring timely and effective delivery of communication data between the base station module and the core network.

[0036] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0038] With the development of technology, Fiber to the Home (FTTH) has become an infrastructure that enables the construction of lines in most scenarios. Users access broadband by connecting to the operator's Optical Line Terminal (OLT) equipment through an optical modem, also known as an Optical Network Unit (ONU). The terminal devices users use daily, such as mobile phones, tablets, and smart home appliances, mostly rely on wireless networks. These wireless networks are typically either wireless signals converted from wired signals by the optical modem (Wi-Fi) or mobile communication network wireless signals transmitted by the operator's base stations, thus ensuring users' daily internet access needs.

[0039] However, wireless networks are obstructed by building structures. Wireless signals emitted by outdoor macro base stations can penetrate building structures to reach indoor terminal devices, or vice versa, resulting in significant signal attenuation. When this attenuation is too great, leading to excessively low signal levels, neither the terminal device nor the macro base station can demodulate the received wireless signal. This causes indoor terminal devices to be unable to access the wireless network or experience communication interruptions. These areas where terminal devices cannot access the wireless network are called dead zones.

[0040] In related technologies, to solve the problem of user terminal equipment access in blind areas, wireless network operators typically deploy a low-cost, low-power, small base station device (i.e., an integrated picocell) in the blind area to provide wireless network access for users in the blind area. It's important to understand that a small base station cannot generate a wireless signal out of thin air; it must connect to the core network to reliably transmit the signal to the blind area. The communication channel between the picocell and the core network is called the backhaul channel. The picocell receives and responds to signaling from the core network, modulates and transmits data from the core network, and simultaneously sends access information and service data from the accessing terminal equipment to the core network, thereby providing access and various services to the terminal equipment.

[0041] Furthermore, in related technologies, the pico base station can be connected to the optical modem via a network port, with the optical modem and upstream OLT equipment providing the backhaul channel for the pico base station. However, during equipment installation, separate installation spaces for the optical modem and pico base station are required, along with separate wiring and power supply schemes, which creates difficulties for equipment installation and management.

[0042] Furthermore, the communication bandwidth between the base station and the core network has a significant impact on the base station's functionality and performance. However, due to the limited data forwarding capabilities of the optical modem, in addition to forwarding communication signals between the base station and core network equipment, it also needs to provide corresponding bandwidth for some terminal devices to achieve data communication. This may affect the communication between the base station and the core network. For example, low bandwidth or high latency between the base station and the core network will directly lead to reduced terminal service speeds, voice stuttering / delay, and other problems. Since optical modems and pico base stations are generally from different manufacturers, it is difficult for these manufacturers to achieve deep cross-device collaborative optimization for data between the base station and the core network.

[0043] To address the problems of the prior art, embodiments of this application provide a communication method, device, storage medium, program product, and converged gateway system. The converged gateway system provided in this application embodiment will be described first below.

[0044] Figure 1 A schematic diagram of the architecture of a converged gateway system provided in one embodiment of this application is shown. Figure 1 As shown, the converged gateway system 100 includes: an optical modem module 110, which includes a first communication interface and a second communication interface, the first communication interface being used for message data transmission with the optical line terminal equipment; and a base station module 120, which is connected to the second communication interface of the optical modem module and is used for message data transmission with the optical modem module.

[0045] For example, the optical modem module can provide data transmission guarantee for the signal extension function of the base station module, that is, the optical modem module provides a bearer for the wireless network between the base station module and the core network.

[0046] In one example, the optical modem module can be an ONU.

[0047] The optical modem module connects to the base station module through the second communication interface and to the OLT device through the first communication interface. The OLT device connects to the core network through the operator's network, thereby establishing a communication channel between the base station module and the core network.

[0048] In one example, Figure 2 This application provides a schematic diagram of the network communication path of a converged gateway system according to an embodiment of the present application. Figure 2 As shown, the data packets sent from the core network to the base station module are routed through the operator's network and forwarded to the OLT device. The OLT device then forwards them to the optical modem module, which in turn forwards them to the base station module. Similarly, the data packets sent from the base station module to the core network follow the same path but in the opposite direction.

[0049] For example, a base station module is a network device connected to the user side of an optical modem module. Furthermore, the base station module needs to communicate with the core network connected to the operator's network.

[0050] The packets carrying communication data in the base station module need to be routed and forwarded through the optical modem module, OLT equipment, and operator network. The communication process and data packets must comply with relevant network communication protocols.

[0051] In one example, the base station module can be a small base station, such as a pico base station.

[0052] In some optional embodiments, the converged gateway system also includes a power supply. The power supply provides power to the optical modem module and the base station module.

[0053] For example, when deploying the wiring of a converged gateway system, only one power cable can be laid to power both the optical modem module and the base station module, thereby simplifying the internal wiring and external connection wiring of the converged gateway system, further simplifying installation and avoiding difficulties in equipment management.

[0054] In one example, the power supply in the converged gateway system can be built-in; alternatively, it can be an external power source. For instance, it can be connected to an external power source via the same power line to power both the optical modem module and the base station module, ensuring the functionality of the converged gateway system.

[0055] In this embodiment, the converged gateway system includes an optical modem module that integrates optical modem functionality and a base station module that integrates base station functionality. By integrating the optical modem module and the base station module, the separate deployment of the optical modem and base station is avoided, effectively reducing the requirements of the device for the installation environment and facilitating the installation and management of the device.

[0056] Below, in conjunction with Figure 3 , Figure 4 The following examples illustrate converged gateway devices.

[0057] Figure 3 This illustration shows a schematic diagram of the location of a converged gateway system in a communication network according to an embodiment of this application. Figure 4 A schematic diagram of the architecture of a converged gateway system provided in one embodiment of this application is shown.

[0058] The converged gateway system integrates the functions of a small base station and an optical modem. The optical modem module in the converged gateway system not only needs to establish communication connections with the base station modules but also needs to provide users with comprehensive service access, such as bandwidth access management services, internet access services, IPTV services, and VoIP services. To achieve the comprehensive service access capabilities of the optical modem module, such as… Figure 3 As shown, the converged gateway system needs to connect to the OLT equipment of the operator's fiber optic cable. The OLT equipment connects to the operator's network, and through correct routing via the corresponding equipment on the operator's network, it can connect to various service platforms and the Internet. The core network equipment of the wireless network consists of specific devices connected to the operator's network. The base station module connects to the optical modem module and, through correct network configuration and routing, establishes a network connection with the core network. Corresponding wireless network services, such as telephone and SMS, are then provided through the core network equipment.

[0059] In one example, the core network may include an evolved packet core (EPC), i.e., a 4G core network; or, the core network may include a 5th generation core network (5GC), i.e., a 5G core network.

[0060] Furthermore, to enable various service access functions within the converged gateway system, the optical modem module not only connects to the OLT device via the incoming fiber optic cable through the first communication interface and to the base station module through the second communication interface, but also includes multiple terminal device communication interfaces. These terminal device communication ports include both wired and wireless types. For example... Figure 4 As shown, the optical modem module includes multiple wired terminal device communication ports, such as network ports 1 to 4. Furthermore, the optical modem module also includes a wireless terminal device communication interface, which can transmit message data via an antenna. Similarly, the base station module can also transmit message data via the wireless terminal device communication interface, i.e., using an antenna, thereby enabling the corresponding wireless network services.

[0061] In one example, such as Figure 4As shown, the first communication interface can be a Passive Optical Network (PON) interface. The second communication interface can be mapped to port 5 of the optical modem module, i.e., LAN5.

[0062] In this embodiment of the application, by constructing a converged gateway system, the requirements for the installation environment are effectively reduced, external connections are reduced, power supply lines are reduced, and the operator's management of the equipment is facilitated.

[0063] Furthermore, the communication method provided in the embodiments of this application will be described. The communication method is applied to the aforementioned converged gateway system.

[0064] Figure 5 A flowchart illustrating a communication method provided in one embodiment of this application is shown. Figure 5 As shown, the communication method includes the following steps:

[0065] S510. In response to receiving message data sent by the first communication interface or the second communication interface, determine the address identifier of the message data.

[0066] S520. If the address identifier of the message data matches any of the preset address identifiers stored in the preset address identifier list, store the message data in the priority forwarding queue.

[0067] S530. Forward the message data according to the storage order of the message data in the priority forwarding queue.

[0068] In some embodiments, in S510, the optical modem module can receive message data sent from the OLT device and message data sent from the base station module through the first communication interface and the second communication interface, respectively. It then determines the address identifier corresponding to the received message data based on the received message data.

[0069] In one example, the message data received by the optical modem module can carry communication data between the base station and the core network.

[0070] In some embodiments, in S520, if it is determined that the address identifier of the message data matches any preset address identifier stored in the preset address identifier list, the message data is stored in the priority forwarding queue.

[0071] For example, the optical modem module may store a list of preset address identifiers, wherein the list contains one or more preset address identifiers. These preset address identifiers can be used as indicators to determine whether packet data should be forwarded preferentially.

[0072] In one example, if the address identifier of the message data matches any of the preset address identifiers stored in the preset address identifier list, it can be determined that the message data needs to be forwarded with priority; conversely, if the address identifier of the message data does not match any of the preset address identifiers stored in the preset address identifier list, it can be determined that the message data does not need to be forwarded with priority.

[0073] In another example, the preset address identifier can be the address identifier corresponding to the core network device.

[0074] For example, the priority forwarding queue stores message data that is to be forwarded and needs to be prioritized for forwarding.

[0075] In one example, when it is determined that a message output needs to be prioritized for forwarding, the message pointer corresponding to the message data can be stored in the priority forwarding queue.

[0076] For example, the priority forwarding queue may include a downlink priority forwarding queue and an uplink priority forwarding queue.

[0077] The data received by the optical modem module from the first communication interface, originating from the operator's network, and needing to be forwarded to other devices on the user side, is called downlink data. In other words, downlink data can be data transmitted from the core network to the base station.

[0078] In some optional embodiments, when the message data is downlink message data received from the first communication interface, if it is determined that the source address identifier of the downlink message data matches any preset address identifier stored in the preset address identifier list, the downlink message data is stored in the downlink priority forwarding queue; and the downlink message data in the downlink priority forwarding queue is forwarded through the second communication interface according to the storage order of the message data in the downlink priority forwarding queue.

[0079] For example, after receiving downlink packet data from the first communication interface, the optical modem module can obtain the source address of the downlink packet data and match the source address identifier of the downlink packet data with the preset address identifiers stored in the preset address identifier list. If it is determined that the source address identifier of the downlink packet data matches any preset address identifier stored in the preset address identifier list, the downlink packet data is stored in the downlink priority forwarding queue and forwarded through the second communication interface.

[0080] The source address identifier of downlink message data can be used to characterize the source of the downlink message data, that is, the network address of the device that sent the message data. In one example, the source address identifier of the downlink message data can be the source Internet Protocol (IP) address.

[0081] When multiple downlink packets are stored in the downlink priority forwarding queue, the downlink packets can be forwarded according to their storage order in the queue. For example, a first-in-first-out (FIFO) approach can be used to forward downlink packets in the downlink priority forwarding queue.

[0082] In this embodiment, when the optical modem module forwards packet data from network-side devices, if it determines that the packet data is downlink packet data received from the first communication interface, originating from the operator network, and needs to be forwarded to other devices on the user side, it determines whether the downlink packet data is a packet that needs to be forwarded with priority. If it determines that the source address identifier corresponding to the downlink packet data matches a preset address identifier list, it can be determined that the downlink packet data needs to be forwarded with priority. Furthermore, the downlink packet data can be stored in a downlink priority forwarding queue and forwarded through the second communication interface. This ensures that the downlink packet data can preferentially occupy the network-side communication bandwidth; that is, the downlink packet data can be preferentially allocated the data transmission bandwidth of the base station backhaul channel, thereby ensuring timely and effective delivery of communication data between the base station module and the core network.

[0083] The message data received by the optical modem module from the base station module via the second communication interface, and which needs to be forwarded to other devices on the network side, is called uplink message data. That is, uplink message data can be data transmitted from the base station to the core network.

[0084] In some optional embodiments, when the message data is uplink message data received from the second communication interface, if it is determined that the destination address identifier of the uplink message data matches any preset address identifier stored in the preset address identifier list, the uplink message data is stored in the uplink priority forwarding queue; and the uplink message data in the uplink priority forwarding queue is forwarded through the first communication interface according to the storage order of the message data in the uplink priority forwarding queue.

[0085] For example, after receiving uplink message data from the second communication interface, the optical modem module can obtain the destination address of the uplink message data and match the destination address identifier of the uplink message data with the preset address identifiers stored in the preset address identifier list. If it is determined that the destination address identifier of the uplink message data matches any preset address identifier stored in the preset address identifier list, the uplink message data is stored in the uplink priority forwarding queue and forwarded through the second communication interface.

[0086] When multiple uplink data packets are stored in the uplink priority forwarding queue, the uplink data packets can be forwarded according to their storage order in the uplink priority forwarding queue. For example, the uplink data packets in the uplink priority forwarding queue can be forwarded in a first-in, first-out (FIFO) manner.

[0087] The source address identifier of uplink message data can be used to identify the recipient of the uplink message data, that is, the network address of the device receiving the message data. In one example, the destination address identifier of the uplink message data can be the destination IP address.

[0088] In this embodiment, when the optical modem module forwards message data from the user-side device, if it determines that the message data is uplink message data received from the base station module via the second communication interface and needs to be forwarded to other devices on the network side, it determines whether the uplink message data is message data that needs to be forwarded with priority. If it determines that the destination address identifier corresponding to the uplink message data matches a preset address identifier list, it can be determined that the uplink message data needs to be forwarded with priority. Furthermore, the uplink message data can be stored in an uplink priority forwarding queue and forwarded through the first communication interface. This ensures that the uplink message data can preferentially occupy the user-side communication bandwidth; that is, the uplink message data can be preferentially allocated the data transmission bandwidth of the base station backhaul channel, thereby ensuring timely and effective delivery of communication data between the base station module and the core network.

[0089] In some embodiments, in S530, the message data can be forwarded according to the storage order of the message data in the priority forwarding queue.

[0090] For example, when the optical modem module receives multiple message data that need to be prioritized for forwarding, it can store the message data in the priority forwarding queue according to the order in which the message data is received, and forward the message data according to the storage order of the message data in the priority forwarding queue.

[0091] In one example, message data can be forwarded in a first-in, first-out order in a priority forwarding queue.

[0092] In some optional embodiments, if it is determined that the data forwarding interface corresponding to the message data is in an idle state, the message data is forwarded according to the storage order of the message data in the priority forwarding queue; or, if it is determined that the data forwarding interface corresponding to the message data is in a message forwarding state, after forwarding the current message data, the message data is forwarded according to the storage order of the message data in the priority forwarding queue. The data forwarding interface corresponding to the message data is either a first communication interface or a second communication interface.

[0093] For example, when forwarding message data, the status of the data forwarding interface corresponding to the message data can be determined, and the timing of forwarding the message data can be determined based on the status of the data forwarding interface corresponding to the message data.

[0094] The data forwarding interface status can include idle status and packet forwarding status. When it is determined that the data forwarding interface corresponding to the packet data is in an idle state, the packet data can be forwarded directly according to the storage order of the packet data in the priority forwarding queue. When it is determined that the data forwarding interface corresponding to the packet data is in a packet forwarding state, the data forwarding interface can continue to forward the current packet data, and after the current packet data has been forwarded, it will forward the packet data according to the storage order of the packet data in the priority forwarding queue.

[0095] Understandably, different message data correspond to different data forwarding interfaces. When the message data is uplink message data, the corresponding data forwarding interface can be the first communication interface; when the message data is downlink message data, the corresponding data forwarding interface can be the second communication interface.

[0096] In this embodiment of the application, when forwarding message data, the forwarding timing of the message data is determined by first judging the status of the data forwarding interface corresponding to the message data. That is, if the data forwarding interface is in an idle state, the message can be forwarded directly. If the data forwarding interface is forwarding other message data, the currently forwarded message data is forwarded first, and then the corresponding message data is forwarded. In this way, the priority of message data between the base station and the core network is guaranteed, while taking into account the overall stability and efficiency of the gateway convergence system.

[0097] For example, when the optical modem module receives message data sent from the first communication interface or the second communication interface, the address identifier of the message data can be determined. It is then determined whether the address identifier corresponding to the message data matches a preset address identifier list. If the address identifier of the message data matches any preset address identifier stored in the preset address identifier list, the message data is stored in a priority forwarding queue. The message data is then forwarded according to the storage order of the message data in the priority forwarding queue. It can be understood that in this embodiment, by determining the address identifier of the message data received by the optical modem module, it is determined whether the message data is a communication signal between the base station and the core network. If so, the message data is stored in the priority forwarding queue, achieving priority forwarding of the message data. This ensures that message data between the base station and the core network can be preferentially allocated the data transmission bandwidth of the base station backhaul channel, thereby guaranteeing timely and effective delivery of communication data between the base station module and the core network.

[0098] Furthermore, in order to ensure the service access function of the optical modem module, as another implementation of this application, this application also provides another implementation of the communication method, as detailed in the following embodiments.

[0099] Figure 6 A flowchart illustrating a communication method provided in one embodiment of this application is shown. Figure 6 As shown, the communication method further includes the following steps S540 and S550:

[0100] S540. If the address identifier of the message data does not match the preset address identifier stored in the preset address identifier list, the message data is stored in a non-priority forwarding queue.

[0101] For example, after the optical modem module obtains the address identifier of the packet data, if it determines that the address identifier of the packet data does not match any of the preset address identifiers stored in the preset address identifier list, it can determine that the packet data belongs to the non-priority forwarding packet data.

[0102] In other words, if the address identifier of the message data does not match any of the preset address identifiers stored in the preset address identifier list, the message data can be considered not to be message data between the base station and the core network, meaning that the message data does not need to be prioritized for forwarding. For example, data that is not prioritized for forwarding can be data used to implement various access services, such as bandwidth access management services, Internet access services, IPTV services, VoIP services, etc.

[0103] For example, a non-priority forwarding queue can be used to store message data that is forwarded but does not require priority forwarding.

[0104] S550. If the priority forwarding queue is determined to be empty, forward the message data according to the storage order of the message data in the non-priority forwarding queue.

[0105] For example, before forwarding packet data in a non-priority forwarding queue, it can be determined whether there is packet data in the priority forwarding queue that needs to be forwarded first, and the forwarding timing of packet data in the non-priority forwarding queue can be determined based on the status of the priority forwarding queue.

[0106] If it is determined that there are packets in the priority forwarding queue that require priority forwarding, then the data in the priority forwarding queue will be forwarded first, and so on, until all packets in the priority forwarding queue have been forwarded before packets in the non-priority forwarding queue are forwarded. Conversely, if it is determined that the priority forwarding queue is empty, that is, all packets in the priority forwarding queue have been forwarded, packets in the non-priority forwarding queue can be forwarded directly.

[0107] In this embodiment of the application, when it is determined that the message data is non-priority forwarding message data, that is, access service data, the access service data can be forwarded through a non-priority queue, thereby ensuring the service access function of the optical modem module.

[0108] For example, the optical modem module can obtain a preset address identifier list from the base station module by communicating with it.

[0109] The base station module can obtain the core network address through the gateway and construct a preset address identifier list based on the core network address. This preset address identifier list is then sent to the optical modem module, enabling the optical modem module to accurately determine which packet data needs to be prioritized for forwarding based on the preset address identifier list.

[0110] In some optional embodiments, the optical modem module can obtain the preset address identifier after the address change through the base station module.

[0111] For example, technicians can change the address of the core network, and after the core network changes the address, the base station module can obtain the changed address identifier of the core network, that is, the preset address identifier after the address change.

[0112] Understandably, after the address corresponding to the core network changes, the corresponding address identifier can be re-obtained through the base station module, and the address identifier after the address change can be updated to the preset address identifier list stored in the optical modem module to ensure the correctness of the address identifier corresponding to the core network, thereby ensuring the correctness of the packet data that needs to be prioritized for forwarding.

[0113] Below, in conjunction with Figure 7 The following examples illustrate the communication method.

[0114] Figure 7 A flowchart illustrating a communication method provided in one embodiment of this application is shown. Figure 7 As shown, in step S701, after detecting that the base station module has accessed the optical modem module through the second communication interface, the base station module obtains the priority forwarding address IP, i.e., the preset address identifier, from the base station module. Specifically, after detecting that the base station module has accessed through the second communication interface, the optical modem module initiates a process of receiving and sending packet data from the second communication interface, and then reads the priority forwarding address IP from the second communication interface to determine whether subsequent packet data is a packet that needs priority forwarding. Furthermore, when the priority forwarding IP address changes, the base station module should proactively send a notification to the optical modem module.

[0115] In step S702, in response to the optical modem module receiving message data from the second communication interface, it is determined whether the destination IP corresponding to the message data is consistent with the address IP that is prioritized for forwarding. If yes, S703 is executed; otherwise, S704 is executed.

[0116] In step S703, the packet data is stored in the uplink priority forwarding queue. In step S704, the packet data is stored in the uplink non-priority forwarding queue.

[0117] Further, in step S705, it can be determined whether the first communication port has not forwarded data. If so, then step S706 is executed to determine whether all packet data in the uplink priority forwarding queue has been forwarded. If not, then return to step S705.

[0118] This can be achieved by determining whether the network-side forwarding port is idle, and whether the first communication port is forwarding data. If it is idle, no data forwarding is being performed; otherwise, data forwarding is being performed.

[0119] After confirming that all packet data in the priority forwarding queue has been forwarded, step S707 is executed to forward packet data in the uplink non-priority forwarding queue. After confirming that all packet data in the priority forwarding queue has not been forwarded, the process returns to step S706.

[0120] Similarly, for downlink message data, in step S708, after the optical modem module receives message data from the first communication interface, it determines whether the source IP corresponding to the message data is consistent with the address IP that is prioritized for forwarding. If yes, proceed to S709; otherwise, proceed to S710.

[0121] In step S709, the message data is stored in the downlink priority forwarding queue. In step S710, the message data is stored in the downlink non-priority forwarding queue.

[0122] Further, in step S711, it can be determined whether the second communication port has not forwarded data. If so, then step S712 is executed to determine whether all packet data in the downlink priority forwarding queue has been forwarded. If not, then return to step S709.

[0123] One way to determine whether the second communication port is forwarding data is to check if the process on the second communication port is idle.

[0124] After determining that all packet data in the priority forwarding queue has been forwarded, step S713 is executed to forward packet data in the downlink non-priority forwarding queue.
