Technical Field

[0001] This disclosure relates to the technical field of data transmission, and more specifically, to a 5G large-tower broadcast data transmission system, method, and apparatus. Background Technology

[0002] With the rapid development of mobile internet, traditional broadcasting methods that only target television receivers can no longer meet user needs. The inability of mobile devices like smartphones to directly receive traditional terrestrial digital television signals has become a major pain point in this field. Against this backdrop, the international mobile communications standards organization 3GPP released the 5G Big Tower Broadcast standard in Release 16. Because 5G Big Tower Broadcast can simultaneously cover traditional television and new media terminals such as mobile phones, it has quickly attracted widespread attention from broadcasting organizations and terrestrial digital television operators worldwide.

[0003] Currently, in practical network infrastructure, the transmission channels for terrestrial digital television single-frequency networks mainly include fiber optics, microwave, and satellite. Not only are fiber optics and microwave difficult to guarantee as bidirectional networks, but satellite transmission is also a typical unidirectional network. If 5G large-tower broadcast services are to be carried on such existing networks, a key technical challenge arises: the M3 interface in the 5G large-tower broadcast standard requires bidirectional communication capabilities between the MME and MCE for dynamically negotiating session parameters, reporting errors, and updating configurations. Providing bidirectional transmission conditions for M3 is difficult. Summary of the Invention

It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0025] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0026] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0027] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0029] <System Implementation> Figure 1 This is a schematic diagram of the structural composition of a 5G large-tower broadcast data transmission system applicable to one embodiment. For example... Figure 1 As shown, the 5G tower broadcast data transmission system can include a first transmission network element and a second transmission network element, and is applied to the construction and operation and maintenance of 5G tower broadcast single frequency network (SFN), especially for the scenario of smoothly upgrading my country's existing terrestrial multimedia broadcast (DTMB) transmission and distribution network to the 5G tower broadcast system.

[0030] The first transmission network element is used to receive one-way service data broadcast by the 5G tower from the single-frequency network.

[0031] In this embodiment, the first transmission network element can be a Mobility Management Entity (MME). One-way service data refers to media stream data originating from the core network, such as a Multimedia Broadcast Multicast Service (MBMS) gateway, that needs to be broadcast to a wide range of end users. This one-way service data is transmitted via the M1 user plane interface protocol.

[0032] The second transmission network element transmits data unidirectionally with the first transmission network element. The second transmission network element is used to receive unidirectional service data based on unidirectional static configuration and output the unidirectional service data to the associated user terminal.

[0033] In this embodiment, the second transmission network element can be a Multi-Cell / Multicast Coordination Entity (MCE) in a 5G large-tower broadcast architecture, or an eNB (evolved Node B) deployed in the 5G large-tower broadcast architecture. In a distributed MCE architecture, the functions of the MCE can be merged into the base station, enabling the second transmission network element to possess all the functions of the MCE itself. One-way static configuration refers to defining the rules for receiving, processing, and forwarding service data based on fixed parameters pre-set locally or in the network management system, without requiring bidirectional signaling interaction with the first transmission network element (such as a Mobility Management Entity (MME)). User terminals can include traditional set-top boxes, mobile phones, tablets, and other new media terminals.

[0034] In this configuration, unidirectional static configuration is built upon specific configuration parameters output unidirectionally by the first transmission network element. These specific configuration parameters are key parameters related to MBMS services, such as service quality, bit rate, priority, and area information. The first transmission network element statically distributes these parameters through the Operation and Maintenance (O&M) interface, rather than negotiating them through dynamic M3 interface signaling procedures. This allows the entire data transmission link to operate independently and stably after configuration, free from complex bidirectional signaling interactions, making it particularly suitable for the numerous unidirectional transmission channels (such as satellite and unidirectional microwave) present in DTMB networks.

[0035] In some embodiments, the second transmission network element is further configured to generate a static configuration interface based on specific configuration parameters unidirectionally transmitted by the first transmission network element; wherein the static configuration interface includes a target signaling group; and a unidirectional static configuration of the second transmission network element is generated based on the configuration operation of the target signaling group.

[0036] Specifically, the second transmission network element can be built into or connected to a graphical O&M configuration interface, i.e., a static configuration interface. This interface pre-sets "target signaling groups" that need to be configured. These signaling groups correspond to signaling parameters that originally required dynamic interaction via the M3 interface. The process of manually or AI-generated assigning values ​​to the parameters of the target signaling groups on this interface is called the "configuration operation." After the configuration operation is completed, the interface generates a static configuration interface containing the specific parameter values, displaying the final configuration result. Finally, the second transmission network element receives and loads this final configuration result, solidifies it, and generates its own "one-way static configuration." In these examples, by providing an intuitive O&M configuration interface, the originally complex M3 signaling process, which required interaction between multiple network elements (MME, MCE), is simplified into a localized static configuration, greatly reducing operational complexity.

[0037] In some embodiments, the signaling groups included in the static configuration interface include a first signaling group and a second signaling group; The first signaling group consists of a single parent signaling group, and the second signaling group consists of a parent signaling group and at least one child signaling group.

[0038] Specifically, signaling on the static configuration interface can be grouped according to its structure. The first signaling group is "flat," meaning that a single signaling item is a complete configuration item in itself, without containing more granular sub-items. The second signaling group has a "hierarchical" structure, with a parent signaling item (e.g., a function category) containing multiple sub-signaling items (e.g., specific parameters of that function). This grouping method helps to clearly organize and present up to dozens of M3 signaling parameters, making it convenient for operations and maintenance personnel to classify, search, and configure them, thus improving the efficiency and accuracy of configuration.

[0039] In these examples, the user-friendliness of the configuration interface can be significantly improved by dividing M3 signaling into different signaling groups according to its structure and function for display and configuration.

[0040] In some embodiments, the second signaling group includes service quality signaling, bit rate service quality signaling, priority signaling, entity identification signaling, area list signaling, and temporary mobile group identifier.

[0041] In this embodiment, these signaling signals are core parameters that ensure the correct establishment and transmission of MBMS services. By incorporating them into the second signaling group for configuration, the basic broadcast function is guaranteed to be implemented.

[0042] In some embodiments, the service quality signaling includes a quality category identifier; the bit rate service quality signaling includes a downlink maximum bit rate and a downlink guaranteed bit rate; the priority signaling includes a priority, a preemption capability parameter, and a preemption parameter; the entity identifier signaling includes an identifier code and an extended code; the area list signaling includes an area code; and the temporary mobile group identifier includes a service unique identifier.

[0043] Furthermore, the parent signaling can contain more specific child signaling, which corresponds to specific information elements (IEs) defined in the M3 protocol. For example: "Service Quality of Service Signalling (MBMS E-RAB QoS parameters)" includes "Quality Category Identifier (QCI)," which can usually be configured to 1, representing the default QoS quality classification; "Bit Rate Service Quality Signalling (GBR QoS Information)" includes "Maximum Bit Rate Downlink (MBMS E-RAB Maximum Bit Rate Downlink)" and "Guaranteed Bit Rate Downlink (MBMS E-RAB Guaranteed Bit Rate Downlink)," with the guaranteed bit rate generally selected; "Allocation and Retention Priority Signalling" includes "Priority Level (selectable from 1-14, with 1 being the highest)," "Pre-emption Capability (Y / N)," and "Pre-emption Vulnerability (Y / N)"; "Global MCE ID Signalling" includes "MCE ID" and "MCE ID Extension"; "MBMS Cell List Signalling" includes "Cell List" and "Cell Code." "Item" refers to the list of base stations; "Temporary Mobility Group Identifier (TMGI)" contains the "Service Unique Identifier (Service ID)". Through the configuration of these sub-signalings, a precise static definition of the core parameters in the M3 protocol is achieved.

[0044] In some embodiments, the first signaling group includes bit rate signaling, Internet Protocol address, endpoint identifier, service area, mobile network identifier, minimum data transmission time, and absolute data transmission time.

[0045] The first signaling group can configure signaling parameters that are themselves "leaf nodes," meaning they do not contain more fine-grained sub-signaling parameters. Examples include "Bit Rate," "IP Address," "GTP-TEID," "MBMS Service Area," "PLMN Identity," "Minimum Time to MBMS Data Transfer," and "Absolute Time of MBMS Data." Treating these signaling parameters as independent, flat configuration items simplifies the configuration process, as they do not require expanding or selecting sub-items; values ​​can be directly entered.

[0046] In some embodiments, the first transmission network element is deployed on the network end of a single-frequency network, and the second transmission network element is directly deployed on the target base station associated with the user end.

[0047] Specifically, in the distributed MCE architecture of 5G large-tower broadcasting, the first transmission network element can be deployed on the core network side or the network end, while the second transmission network element is deployed on the base station side of the radio access network. For the transformation scenario of DTMB single-frequency networks, the logical functions of the MCE can be merged into the base station equipment; that is, the "second transmission network element" itself or its associated control unit includes the static configuration functions of the MCE. Therefore, from a physical deployment perspective, the second transmission network element is directly located at the target base station associated with the user end, responsible for the final signal transmission, while the first transmission network element acts as a source node located upstream on the network end, providing configuration parameters. This deployment method allows the base station to break free from its dependence on bidirectional signaling from the core network, achieving localized autonomous configuration.

[0048] The 5G tower broadcast data transmission system in this embodiment eliminates the complex dynamic signaling process of the M3 interface. Instead of obtaining MBMS service-related parameters through bidirectional signaling negotiation via the MCE, it performs unidirectional static configuration locally. This allows the second transmission network element to stably receive and forward unidirectional service data broadcast by the 5G tower in a unidirectional network environment, relying solely on pre-configured parameters. This system solves the technical challenge of establishing bidirectional communication via the 5G tower broadcast M3 interface under unidirectional transmission conditions such as fiber optics, microwave, and especially satellite. It achieves smooth adaptation to existing DTMB single-frequency networks, requiring only the replacement of the exciter to complete the network upgrade, significantly reducing construction costs.

[0049] <Method Implementation> Figure 2 This is a flowchart illustrating a 5G tower broadcast data transmission method according to one embodiment. Figure 2As shown, the 5G tower broadcast data transmission method of this embodiment may include the following steps S210 to S230: In step S210, the first transmission network element receives unidirectional service data broadcast by the 5G tower from the single-frequency network output.

[0050] In step S220, the second transmission network element receives unidirectional service data based on a unidirectional static configuration; wherein, the unidirectional static configuration is constructed based on specific configuration parameters output unidirectionally by the first transmission network element.

[0051] In step S230, the second transmission network element outputs unidirectional service data to the associated user terminal.

[0052] The specific implementation methods, technical effects, and explanations of terms such as "first transmission network element," "second transmission network element," "one-way static configuration," and "specific configuration parameters" involved in the above steps S210, S220, and S230 are the same as the corresponding description of the 5G large tower broadcast data transmission system in Embodiment 1, and will not be repeated here.

[0053] In some embodiments, the method further includes a static configuration generation step before step S210. Specifically: For example, before step S210, the method further includes: specific configuration parameters unidirectionally output by the first transmission network element; the second transmission network element generating a static configuration interface based on the specific configuration parameters unidirectionally transmitted by the first transmission network element; wherein the static configuration interface includes a target signaling group; and the second transmission network element generating a unidirectional static configuration based on the configuration operation of the target signaling group.

[0054] The core of this step lies in eliminating all seven processes in the M3 protocol (MBMS session startup, stop, update, reset, M3 establishment, MCE configuration update, and error indication). Instead, signaling related to MBMS services (such as QCI, Bit Rate, TMGI, etc.) is extracted and statically assigned manually or semi-automatically as target signaling groups on the MCE's O&M interface. Signaling unrelated to MBMS services (such as Message Type, Cause, MCE MBMS M3AP ID, etc.) is ignored without any configuration. After the maintenance personnel complete the configuration on the O&M interface, the system generates the final one-way static configuration and distributes or persists this configuration to the second transmission network element (base station). During this process, the base station no longer needs to perform M3 Setup procedures with the MME, nor does it need to handle dynamic session startup and shutdown; its operating state is entirely determined by the local static configuration.

[0055] As can be seen from steps S210 to S230 above, the 5G tower broadcast data transmission method of this embodiment fully simulates the core functions of the M3 interface through two steps: process cancellation and static parameter configuration, and realizes service data reception and forwarding in a unidirectional network environment. This method, with its clear steps and procedures, provides specific and operable technical guidance for network upgrades and transformations in actual engineering projects, ensuring that the 5G tower broadcast system can be deployed quickly and at low cost on existing DTMB transmission and distribution networks.
