Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a voice switching method and apparatus based on semi-static scheduling. Background Technology

[0002] With the development of communication technology, in order to achieve full network signal coverage, the overlapping coverage areas between different cells are increasing. As network load gradually increases, downlink interference in these overlapping coverage areas becomes more severe. In addition, the deployment of time-synchronized networking will further increase physical downlink control channel (PDCCH) interference.

[0003] Interference with the PDCCH causes it to be restricted, resulting in the base station not receiving the measurement report (MR) reported by the user equipment. Therefore, the base station cannot promptly switch resources for the user equipment's current service based on the MR, leading to the reconstruction or disconnection of the current service. Summary of the Invention

[0004] This application provides a semi-static scheduling-based voice switching method and apparatus, which enables timely resource switching of voice services when PDCCH is limited.

[0005] In a first aspect, embodiments of this application provide a voice handover method based on semi-static scheduling, specifically including: after a voice service connection is established, a network device activates semi-static scheduling and issues time-frequency resources and modulation and coding strategies; within the scheduling period of the semi-static scheduling, the network device uses the time-frequency resources and the modulation and coding strategies to receive a measurement report sent by a user terminal; the network device sends a handover instruction to the user terminal according to the measurement report, so that the user terminal performs voice service handover according to the handover instruction.

[0006] In this embodiment, the network device can utilize semi-statically scheduled time-frequency resources and scheduling and coding strategies to receive measurement reports reported by the user terminal, thereby enabling monitoring of the channel quality where the user terminal is located. When the channel quality of the user terminal is poor, timely switching can be achieved to ensure service quality.

[0007] Optionally, before activating the semi-static scheduling, the network device can pre-set the size of the uplink semi-static scheduling measurement report (MR), the uplink scheduling period, and the downlink scheduling period. The size of the uplink semi-static scheduling measurement report can be obtained by statistically analyzing the sizes of various measurement reports in the existing network. That is, the pre-set size of the schedulable measurement report needs to satisfy the data volume of most measurement reports. Specifically, the size of the uplink semi-static scheduling measurement report is 40 bytes. This ensures that the data volume of the schedulable measurement report will not affect uplink order selection and thus demodulation reliability, nor will it prevent MR fragmentation caused by incomplete MR transmission in a single semi-static scheduling operation, thereby affecting MR scheduling.

[0008] Optionally, to avoid voice service outages or reconstructions, the uplink scheduling period of this semi-static scheduling needs to be less than the reconstruction time for the maximum number of retransmissions. To further reduce the impact on voice services, the uplink scheduling period can be set to the maximum protocol duration of 640 milliseconds. Since the downlink scheduling power is higher than the uplink, its downlink scheduling period can remain unchanged at 20 milliseconds.

[0009] Optionally, in the downlink scheduling of this semi-static scheduling, after receiving a measurement report, if the measurement report indicates that the quality of the cell to which the current voice service is accessed is lower than a threshold, the network device can generate a corresponding handover instruction based on the measurement report, and then use the time-frequency resources and 0 / 1 order scheduling of the semi-static scheduling to schedule the handover instruction, and send the handover instruction to the user terminal so that the user terminal can access other cells for the current voice service according to the handover instruction.

[0010] Optionally, when scheduling the switching instruction in a semi-static scheduling state, the size of the switching instruction is 80 bytes or the size of the voice data packet is greater than 80 bytes.

[0011] Optionally, during the process of receiving the measurement report and downlink handover command, the network device dynamically schedules the voice data packets for the voice service. This can prevent voice data packet loss from affecting the quality of the voice service.

[0012] Secondly, this application provides a voice switching device that has the function of implementing the network device behavior described in the first aspect above. This function can be implemented by hardware or by hardware executing corresponding software. The hardware or software includes one or more modules corresponding to the aforementioned function.

[0013] In one possible implementation, the apparatus includes units or modules for performing the steps of the first aspect above. For example, the apparatus includes: a processing module for activating semi-static scheduling after a voice service connection is established; a transmitting module for issuing time-frequency resources and modulation and coding strategies; a receiving module for receiving a measurement report sent by a user terminal using the time-frequency resources and the modulation and coding strategies during the scheduling period of the semi-static scheduling; and the transmitting module for sending a handover instruction to the user terminal according to the measurement report, so that the user terminal performs voice service handover according to the handover instruction.

[0014] Optionally, a storage module may also be included to store the necessary program instructions and data for the voice switching device.

[0015] In one possible implementation, the device includes a processor and a transceiver, the processor being configured to support the network device in performing the corresponding functions of the method provided in the first aspect above. The transceiver is used to instruct communication between the network device and the user terminal, sending the switching instructions involved in the method to the user terminal. Optionally, the device may also include a memory coupled to the processor, which stores program instructions and data necessary for the voice switching device.

[0016] In one possible implementation, when the device is a chip within a voice switching device, the chip includes a processing module and a transceiver module. The processing module may be, for example, a processor, which activates semi-static scheduling after a voice service connection is established. The transceiver module may be, for example, an input / output interface, pins, or circuits on the chip, transmitting instructions generated by the processor to other chips or modules coupled to this chip. The processing module can execute computer-executable instructions stored in a storage unit to support the voice switching device in performing the method provided in the first aspect above. Optionally, the storage unit may be a storage unit within the chip, such as a register or cache. Alternatively, the storage unit may be a storage unit located outside the chip, such as read-only memory (ROM) or other types of static storage devices capable of storing static information and instructions, such as random access memory (RAM).

[0017] In one possible implementation, the device includes a processor, a baseband circuit, a radio frequency (RF) circuit, and an antenna. The processor controls the functions of each circuit section, the baseband circuit generates instructions, which are then processed by the RF circuit through analog-to-digital conversion, filtering, amplification, and up-conversion before being transmitted to the user terminal via the antenna. Optionally, the device also includes a memory that stores necessary program instructions and data for the voice switching device.

[0018] In one possible implementation, the device includes a communication interface and logic circuitry. The logic interface is used to activate semi-static scheduling after a voice service connection is established. The communication interface is used to distribute time-frequency resources and modulation and coding strategies. During the scheduling period of the semi-static scheduling, a measurement report sent by a user terminal is received using the time-frequency resources and the modulation and coding strategies. A handover command is sent to the user terminal according to the measurement report, so that the user terminal performs voice service handover according to the handover command.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application are described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Those skilled in the art will understand that with the emergence of new application scenarios, the technical solutions provided by the embodiments of this application are also applicable to similar technical problems.

[0031] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or device that includes a series of steps or modules is not necessarily limited to those explicitly listed, but may include other steps or modules not explicitly listed or inherent to such processes, methods, products, or devices. The naming or numbering of steps appearing in this application does not imply that the steps in the method flow must be performed in the chronological / logical order indicated by the naming or numbering. The execution order of named or numbered process steps can be changed according to the desired technical purpose, as long as the same or similar technical effect is achieved. The division of units in this application is a logical division. In practical applications, there may be other division methods. For example, multiple units may be combined or integrated into another system, or some features may be ignored or not executed. In addition, the shown or discussed mutual coupling, direct coupling, or communication connection may be through some interface, and the indirect coupling or communication connection between units may be electrical or other similar forms, none of which are limited in this application. Furthermore, the units or sub-units described as separate components may or may not be physically separated, may or may not be physical units, or may be distributed among multiple circuit units. Some or all of the units can be selected to achieve the purpose of the solution in this application according to actual needs.

[0032] With the development of communication technology, in order to achieve full network signal coverage, the overlapping coverage areas between different cells are increasing. However, as network load gradually increases, downlink interference in these overlapping coverage areas becomes more severe. Furthermore, the deployment of time-synchronized networks adds additional PDCCH interference. This PDCCH interference leads to PDCCH limitation, resulting in the MR base station failing to receive reports from user equipment. Figure 1 As shown, when a user terminal is conducting voice services with a base station, if the PDCCH is restricted, the user terminal cannot detect the downlink control information (DCI) sent by the base station, which is equivalent to the base station not receiving the uplink measurement report. At this time, the user terminal will send uplink scheduling requests to the base station multiple times. When the uplink scheduling request exceeds the maximum number of retransmissions (64), the current service will be rebuilt or dropped.

[0033] To address this issue, this application provides the following technical solution: After a voice service connection is established, the network device activates semi-static scheduling and distributes time-frequency resources and modulation and coding strategies; within the scheduling period of the semi-static scheduling, the network device uses the time-frequency resources and the modulation and coding strategies to receive measurement reports sent by user terminals; the network device sends a handover instruction to the user terminal based on the measurement report, so that the user terminal can switch voice services according to the handover instruction.

[0034] For ease of understanding, some terms in the embodiments of this application are explained below:

[0035] Semi-persistent scheduling (SPS), also known as semi-permanent scheduling, differs from dynamic scheduling, which allocates radio resources to user terminals once every transport time interval (TTI) (specified via PDCCH). SPS allows for semi-static configuration of radio resources, periodically allocating these resources to a specific user terminal. For voice services, dynamic scheduling requires updating time-frequency resources or modulation and coding schemes (MCS) via PDCCH every 20 milliseconds, resulting in significant PDCCH resource consumption. For small-packet services like Voice over Internet Protocol (VoIP) with periodic transmission, the semi-persistent scheduling feature of VoIP is introduced. The specific process can be described as follows... Figure 2As shown, when entering a call period, the base station (eNodeB) allocates a fixed amount of resources to the user terminal once via PDCCH messages (i.e., activates semi-static scheduling and distributes time-frequency resources and MCS). Before exiting the call period or releasing resources, it is not necessary to allocate resources again via PDCCH, thus saving PDCCH resources. During the static period or when resources are released, the semi-static scheduling can be activated directly.

[0036] Figure 3 This is a schematic diagram of the architecture of a mobile communication system used in an embodiment of this application. As shown in the figure, the mobile communication system includes a core network device 301, a radio access network device 302, and at least one terminal device (such as...). Figure 3 Terminal devices 303 and 304 are included in this document. The terminal devices connect wirelessly to the wireless access network equipment, which in turn connects wirelessly or via a wired connection to the core network equipment. The core network equipment and the wireless access network equipment can be independent physical devices, or they can integrate the functions of the core network equipment and the logical functions of the wireless access network equipment onto the same physical device. Alternatively, a single physical device can integrate some of the functions of the core network equipment and some of the functions of the wireless access network equipment. The terminal devices can be fixed in location or mobile.

The embodiments of this application do not limit the application scenarios of the wireless access network equipment and terminal equipment.

[0040] The embodiments of this application can be applied to both downlink and uplink signal transmission. For downlink signal transmission, the transmitting device is a wireless access network device, and the corresponding receiving device is a terminal device. For uplink signal transmission, the transmitting device is a terminal device, and the corresponding receiving device is a wireless access network device.

They can also communicate using spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used between the WLAN devices and terminal devices.

[0042] The following is combined with Figure 4 The following describes the voice switching method based on semi-static scheduling in the embodiments of this application:

[0043] 401. The network device establishes a voice service with the user terminal.

[0044] When a user terminal engages in voice services with other user terminals, the network device establishes a channel with the user terminal for voice service data transmission.

[0045] 402. During the call, the network device activates the semi-static scheduling and sends time-frequency resources and MCS to the user terminal.

[0046] During a voice call, the network device activates the semi-static scheduling and sends the voice data packets, measurement reports, and time-frequency resources and MCS used by the handover command for the voice service during the semi-static scheduling period to the user terminal.

[0047] Optionally, before activating the semi-static scheduling, the network device can also pre-set the size of the uplink semi-static scheduling MR and the uplink scheduling period and downlink scheduling period in the semi-static scheduling.

[0048] The size of the measurement report for this semi-static uplink scheduling can be obtained by statistically analyzing the sizes of various measurement reports in the existing network. Table 1 shows the statistical breakdown of the measurement report sizes.

[0049] Table 1

[0050] Measurement report size range (bits) count Percentage (%) 3-5 84 1.00 5-7 133 1.58 7-9 81 0.96 9-11 157 1.86 11-13 188 2.23 13-15 825 9.78 15-17 479 5.68 17-19 1197 14.19 19-21 1507 17.86 21-23 1054 12.49 23-25 1025 12.15 25-27 657 7.79 27-29 418 4.95 29-31 287 3.40 31-33 225 2.67 33-35 84 1.00 35-37 9 0.11 37-39 22 0.26 41-43 5 0.06 43-45 1 0.01 total 8438

[0051] As shown in Table 1 above, among the total 8438 measurement reports, the maximum data size of a measurement report is 45 bits, while the data size of most measurement reports ranges from 13 bits to 33 bits. The pre-set size of the schedulable measurement report needs to accommodate the data size of most measurement reports. Specifically, the size of the uplink semi-static scheduled measurement report is 40 bytes. This ensures that the data size of the schedulable measurement report will not affect uplink order selection and thus demodulation reliability, nor will it prevent a single semi-static scheduling from failing to transmit the entire MR, leading to MR fragmentation and thus affecting MR scheduling.

[0052] Optionally, to avoid voice service outages or reconstructions, the uplink scheduling period of this semi-static scheduling needs to be less than the reconstruction time for the maximum number of retransmissions. To further reduce the impact on voice services, the uplink scheduling period can be set to the maximum protocol duration of 640 milliseconds. Since the downlink scheduling power is higher than the uplink, its downlink scheduling period can remain unchanged at 20 milliseconds.

[0053] 403. During the scheduling period of the semi-static scheduling, the network device uses the time-frequency resources and the MCS to schedule the measurement report generated by the user terminal.

[0054] During the semi-static scheduling period, the network device checks whether the user terminal has a MapReduce (MR) that needs to be scheduled. If so, the network device prioritizes using the semi-static scheduling time-frequency resources and MCS to schedule the MR. At this time, the network device switches the voice data packets of the voice service to dynamic scheduling. This prevents voice services from being affected.

[0055] 404. The network device sends a handover command to the user terminal based on the measurement report.

[0056] When the measurement report indicates that the quality of the current voice service of the user terminal is lower than a preset threshold, the network device can determine the voice service to be switched according to the measurement report, and then generate a switching instruction to send the switching instruction to the user terminal.

[0057] In this embodiment, after generating the handover instruction, the network terminal can also obtain the size of the data volume of the handover instruction. Then, when the size of the handover instruction meets the preset downlink scheduling signaling size, the handover instruction is scheduled using the time-frequency resources of the semi-static scheduling and the 0 / 1 order scheduling. Specifically, when scheduling the handover instruction in the semi-static scheduling state, the size of the handover instruction is 80 bytes or the size of the voice data packet is greater than 80 bytes.

[0058] 405. The user terminal switches voice services according to the switching instruction.

[0059] In this embodiment, the switching instruction is used to instruct the user terminal to perform voice switching related information; then the user terminal performs voice service channel switching according to the voice switching related information, thereby ensuring the transmission quality of voice data packets of the voice service and thus avoiding the voice service from being affected.

[0060] In this embodiment, the network device can utilize semi-statically scheduled time-frequency resources and scheduling and coding strategies to receive measurement reports reported by the user terminal, thereby enabling monitoring of the channel quality where the user terminal is located. When the channel quality of the user terminal is poor, timely switching can be achieved to ensure service quality.

[0061] The above describes a voice switching method based on semi-static scheduling in the embodiments of this application. It is understood that, in order to achieve the above functions, the voice switching device includes corresponding hardware structures and / or software modules for executing each function.

Whether a function is executed in hardware or by computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of this application.

[0062] This application embodiment can divide the voice switching device into functional modules according to the above method example. For example, each function can be divided into its own functional module, or two or more functions can be integrated into one processing module. The integrated module can be implemented in hardware or as a software functional module. It should be noted that the module division in this application embodiment is illustrative and only represents one logical functional division. In actual implementation, there may be other division methods.

Specifically, in the technical solutions provided in the embodiments of this application, the transmitter 5021 can specifically be used to perform, for example, operations performed by the receiving module or the transceiver module in the voice switching device when the semi-static scheduling-based voice switching method is applied to the voice switching device in subsequent method embodiments.

[0067] The processor 504 can be used to execute the instructions stored in the memory 503 to control the transceiver 502 to receive and / or send messages, thus fulfilling the function of the voice switching device in the method embodiment of this application. As one implementation, the function of the transceiver 502 can be implemented through a transceiver circuit or a dedicated transceiver chip. In this embodiment, receiving messages by the transceiver 502 can be understood as inputting messages to the transceiver 502, and sending messages by the transceiver 502 can be understood as outputting messages to the transceiver 502.
