Given the rapid development in the field of communications, there will certainly be future types of communication technologies and systems that can be used to implement this disclosure. This should not be construed as limiting the scope of this disclosure to only the aforementioned systems.

[0022] As used herein, the term "network device" refers to a node in a communication network through which terminal devices access the network and receive services. Depending on the terminology and technology applied, network devices can refer to base stations (BS) or access points (APs), such as Node B (NodeB or NB), evolved Node B (eNodeB or eNB), NR NB (also known as gNB), Remote Radio Unit (RRU), Radio Head (RH), Remote Radio Head (RRH), relay, Integrated Access and Backhaul (IAB) nodes, low-power nodes such as femtoseconds and picoseconds, etc.

In the following description, the terms "terminal device," "network device," "terminal," "user equipment," and "UE" are used interchangeably.

[0024] As mentioned above, CDRX technology is now widely used in Long Term Evolution (LTE) and 5G communication systems to manage the power of terminal devices in communication control. CDRX technology is used to save power consumption of terminal devices when they are in a communication connection state. Based on CDRX technology, even when the terminal device is in a communication connection state with network devices (e.g., intermittently transmitting and receiving data), the baseband transceiver of the terminal device can sleep and turn off radio frequency transmission and reception, thereby reducing the power consumption of the terminal device.

[0025] However, in some communication scenarios, the CDRX mode between the terminal device and the network device may be in an unconfigured state (or disabled). If frequent data transmission and reception continue between the terminal device and the network device in this situation, the terminal device will maintain a communication connection without CDRX configuration. Consequently, the baseband transceiver of the terminal device will not go into sleep mode or shut down, leading to significant power consumption. An example communication scenario could be: in scenarios with high data transmission and reception activity (e.g., high throughput data transmission and reception), the operator's network equipment may disable CDRX mode to provide excellent data transmission performance. After the high data transmission and reception activity ends, the operator's network equipment may fail to reconfigure CDRX due to various reasons (e.g., configuration errors), resulting in the current Radio Resource Control (RRC) connection remaining in an unconfigured CDRX state. In this case, if the terminal device still has low data transmission and reception activity, the previous RRC connection will remain in a long-term connection state, leading to severe power consumption of the terminal device.

[0026] It should be understood that only example communication scenarios applicable to the embodiments of this disclosure are given herein. In practical applications, there may be many more communication scenarios where the power consumption of the terminal device is high due to the CDRX being in an unconfigured state.

[0027] In view of this, embodiments of the present disclosure propose a communication control scheme. According to the scheme of the embodiments of the present disclosure, firstly, the state of CDRX between the terminal device and the network device is determined. If the state indicates that CDRX is in an unconfigured state, based on at least one of the duration of the unconfigured state of CDRX and the data transmission and reception status of the terminal device, it is determined whether to trigger reconnection. Further, if it is determined that reconnection should be triggered, a reconnection operation between the terminal device and the network device is triggered.

[0028] In this way, during communication between the terminal device and the network device, if the terminal device determines that the CDRX between the terminal device and the network device is in an unconfigured state, it can trigger a reconnection operation between the terminal device and the network device, thereby inducing the network device to restore the CDRX configuration of the terminal device. This solves the problem of increased power consumption of the terminal device when the CDRX is in an unconfigured state, especially for terminal devices that frequently experience intensive data transmission and reception, reducing power consumption of this type of terminal device while ensuring good data communication performance.

[0029] The following section provides a detailed description of various example implementations of this scheme, with reference to the accompanying drawings.

[0030] Figure 1A schematic diagram of an example environment 100 in which embodiments of the present disclosure can be implemented is shown. For example... Figure 1 As shown, example environment 100 may include terminal device 110 and user 130. Terminal device 110 may be any type of mobile terminal, fixed terminal, or portable terminal with communication capabilities, including mobile phones, desktop computers, laptop computers, notebook computers, netbook computers, tablet computers, media computers, multimedia tablets, handheld computers, portable gaming terminals, VR / AR devices, personal communication system (PCS) devices, personal navigation devices, personal digital assistants (PDAs), audio / video players, digital cameras / camcorders, positioning devices, television receivers, radio receivers, e-book devices, gaming devices, or any combination thereof, including accessories and peripherals of these devices or any combination thereof. In some embodiments, terminal device 110 may also support any type of interface for user 130 (such as "wearable" circuitry). Terminal device 110 may be a single terminal device or a combination of multiple terminal devices of any type, including accessories and peripherals of the devices or any combination thereof.

[0031] In this example environment 100, terminal device 110 may run client 111 and baseband transceiver 112. As an example, client 111 may correspond to the operating system of terminal device 110. As another example, client 111 may correspond to any type of application installed on terminal device 110. The application can be any suitable type of application that terminal device 110 can run, and examples may include, but are not limited to, social applications, game applications, or other suitable applications. User 130 can interact with the application via terminal device 110 and / or its attached devices. Baseband transceiver 112 can be used to send and receive data with network device 121 of network 120.

[0032] The communication control network 120 can provide any communication services required by the user 130, including voice calls, video calls, SMS and MMS services, data internet access services, etc. In this example environment 100, the network device 121 of the network 120 can send and receive data with the baseband transceiver 112 of the terminal device 110, and the network device 121 can connect to the server 122. Communication between the terminal device 110 and the network device 121 can be implemented according to any appropriate communication protocol(s). Examples of communication protocols include, but are not limited to, cellular communication protocols such as first generation (1G), second generation (2G), 2.5G, 2.75G, third generation (3G), fourth generation (4G), 4.5G, fifth generation (5G), and sixth generation (6G), wireless local area network communication protocols such as IEEE 802.11, and / or any other protocols currently known or to be developed in the future.

[0033] Server 122 can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks, and big data and artificial intelligence platforms. Server 122 may include, for example, computing systems / servers such as mainframes, edge computing nodes, computing devices in a cloud environment, etc. Server 122 can perform data processing to respond to user communication needs.

[0034] It should be understood that the structure and function of the various elements in environment 100 are described for illustrative purposes only and do not imply any limitation on the scope of this disclosure.

[0035] The following description will continue with reference to the accompanying drawings, which will provide some exemplary embodiments of this disclosure.

[0036] Figures 2 to 3 Flowcharts of example communication control processes 200 and 300 according to some embodiments of the present disclosure are shown. Communication control processes 200 and 300 can be based on... Figure 1 The environment shown is 100% achieved. The following is combined with... Figure 1 To describe Figure 2 and Figure 3 The data communication process is shown.

[0037] like Figure 2 As shown, during communication between terminal device 110 and network 120, the baseband transceiver 112 of terminal device 110 can receive the CDRX status configuration of terminal device 110 from network device 121. This status configuration can configure terminal device 110 to operate in CDRX mode or not in CDRX mode.

[0038] In embodiments of this disclosure, baseband transceiver 112 sends (211) the status of the CDRX between terminal device 110 and network device 121 to client 111 of terminal device 110. The CDRX status between terminal device 110 and network device 121 can include a configured state and a non-configured state. If the CDRX is in a configured state, it indicates that terminal device 110 is allowed to periodically enter a sleep state while maintaining a communication connection with network device 121. In the CDRX sleep state, terminal device 110 can avoid listening to the Physical Downlink Control Channel (PDCCH) from network device 121, thereby reducing the power consumption of terminal device 110. If terminal device 110 needs to receive downlink data or send uplink data, terminal device 110 can also wake up from the sleep state to enter a wake-up state, allowing terminal device 110 to perform normal data transmission and reception operations. In embodiments of this disclosure, a non-configured CDRX state indicates that network device 121 has not configured the CDRX or that the CDRX configuration information is incorrect. If CDRX is in an unconfigured state and the terminal device 110 performs low-activity data transmission and reception, the terminal device 110 cannot enter a sleep state, which leads to high power consumption of the terminal device 110 and reduces the usage time of the terminal device 110.

[0039] As an example, the specific communication process between terminal device 110 and network device 121 can be found in [reference]. Figure 3 .like Figure 3 As shown, if client 111 determines that terminal device 110 needs to communicate with network device 121, client 111 can establish a (311) communication connection. After receiving the notification from client 111 to establish a communication connection, baseband transceiver 112 can first establish a (312) Protocol Data Unit (PDU) / Packet Data Network (PDN) connection. PDU, as a data unit exchanged between different layers in the communication protocol stack, can realize data encapsulation, transmission, and decapsulation. PDN is the external data network accessed by terminal device 110 during communication. It is understandable that the PDU / PDN connection can provide terminal device 110 with a channel to access the external data network.

[0040] Continue to refer to Figure 3After establishing (312) the PDU / PDN connection, the baseband transceiver 112 then establishes (313) an RRC connection between the terminal device 110 and the network device 121 of the network 120. The RRC connection is the channel for data transmission between the terminal device 110 and the network device 121 during communication. The RRC connection ensures effective data transmission between the terminal device 110 and the network device 121. After the RRC connection is established, the network device 112 can configure CDRX information and send (314) the status of the CDRX between the terminal device 110 and the network device 121 to the terminal device 110. The baseband transceiver 112 of the terminal device 110 can receive the CDRX status sent by the network device 121 and send the CDRX status to the client 111 of the terminal device 110 (315).

[0041] Furthermore, if client 111 determines (316) that the CDRX between terminal device 110 and network device 121 is in a configured state, it can perform normal data transmission and reception (317) with network device 121. Understandably, when configuring the CDRX, terminal device 110 and network device 121 can perform low-activity data transmission and reception. For example, if the number of applications in active state (or usage state) on terminal device 110 is less than a certain threshold, terminal device 110 may perform low-activity data transmission and reception. As an example communication scenario, assuming the threshold is 1, if terminal device 110 is in a pure desktop state, or if there are no active applications on terminal device 110, terminal device 110 may perform low-activity data transmission and reception. For another example, if the data throughput rate of terminal device 110 is less than a certain rate threshold, terminal device 110 may perform low-activity data transmission and reception. As an example of a communication scenario, terminal device 110 uses a 4G network for communication. If the data throughput rate of terminal device 110 is lower than the rate threshold of 1MB / s, terminal device 110 may perform low-activity data transmission and reception.

[0042] Similarly, depending on specific needs, high-activity data transmission and reception may also be required between terminal device 110 and network device 121. For example, if the number of applications in active state (or usage state) on terminal device 110 is equal to or higher than a certain threshold, terminal device 110 may be in a high-activity data transmission and reception state. As an example communication scenario, assuming the threshold is 1, if there are 5 active applications on terminal device 110, terminal device 110 may be in a high-activity data transmission and reception state. As another example, if the data throughput rate of terminal device 110 is equal to or higher than a certain rate threshold, terminal device 110 may be in a high-activity data transmission and reception state. As an example communication scenario, if terminal device 110 uses a 5G network for communication, and its data throughput rate is higher than the rate threshold of 10MB / s, terminal device 110 may be in a high-activity data transmission and reception state. Understandably, the parameters (such as the aforementioned number threshold and rate threshold) can be adjusted according to the communication network adaptability of terminal device 110. For example, higher number and / or rate thresholds can be set for 5G networks compared to 4G networks. It should be understood that this is only an example communication scenario involving low / high activity data transmission and reception; in practical applications, more, fewer, or other communication scenarios can be considered depending on the data transmission and reception situation.

[0043] Continue to refer to Figure 3 If high-activity data transmission and reception are performed between terminal device 110 and network device 121, or if high-speed data transmission occurs between terminal device 110 and network device 121, network device 121 may not reconfigure CDRX after the high-speed data transmission ends. In this case, network device 121 sends (318) a status indication of CDRX between terminal device 110 and network device 121 to terminal device 110, indicating that CDRX is in an unconfigured state. Then, baseband transceiver 112 of terminal device 110 receives the CDRX status sent by network device 121 and sends (211) the received CDRX status to client 111.

[0044] Reference Figure 2 Client 111 determines (212) that CDRX is in an unconfigured state based on the state of the received CDRX. Further, client 111 determines (213) whether to trigger reconnection between terminal device 110 and network device 121 based on at least one of the duration of CDRX's unconfigured state and the data transmission and reception status of terminal device 110.

[0045] Figure 4 A flowchart illustrating an example process 400 for determining a trigger for reconnection according to some embodiments of the present disclosure is shown. Process 400 can be considered as... Figure 2 and Figure 3 Example implementation of operation 213 in the example.

[0046] like Figure 4 As shown, in box 410, client 111 determines that the CDRX of terminal device 110 is in an unconfigured state based on the received CDRX status. For a period of time, in box 420, client 111 can continue to determine whether the CDRX of terminal device 110 is still in an unconfigured state. This is because the CDRX might be in an unconfigured state due to high-activity data transmission and reception requirements between terminal device 110 and network device 121, but such high-speed data transmission and reception requirements usually do not last long. In box 430, if client 111 determines that the CDRX of terminal device 110 is in a configured state, meaning the CDRX configuration state has been restored, then it can exit the current process 400 of determining to trigger a reconnection.

[0047] In box 440, if client 111 determines that CDRX is still in an unconfigured state (e.g., the duration exceeds a threshold), it continues to determine whether the data throughput rate of terminal device 110 is lower than the rate threshold. If client 111 determines that the data throughput rate of terminal device 110 is equal to or higher than the rate threshold, it restarts the determination of whether CDRX is still in an unconfigured state. In box 450, if client 111 determines that the data throughput rate of terminal device 110 is lower than the rate threshold, it can increment the count of the wait counter by 1, and can execute box 460 after waiting for a predetermined time (e.g., 10 seconds).

[0048] In box 460, client 111 can determine whether the wait counter count is greater than a predetermined value (e.g., 2). If client 111 determines that the wait counter count is equal to or less than the predetermined value (e.g., 2), it returns to box 420 to determine whether CDRX remains in an unconfigured state, etc. If it determines that the wait counter count is greater than 2 (e.g., 2), then in box 470, client 111 can determine to trigger a reconnection operation between terminal device 110 and network device 121.

[0049] In other words, based on Figure 4 In example process 400, client 111 can determine to trigger reconnection when it is determined that the CDRX has been in an unconfigured state for a preset duration (e.g., 30s) and the data throughput rate of terminal device 110 remains below the rate threshold within the preset duration.

[0050] It is understandable that the above-mentioned parameters, such as the scheduled time and the scheduled value related to the waiting counter, can be arbitrarily configured according to actual needs; the above description is merely an example. It should be understood that... Figure 4The process 400 shown is only an example flow for determining whether to trigger a reconnection. In actual applications, more, less, or other communication information can be combined as needed to determine whether to trigger a reconnection operation between the terminal device 110 and the network device 121.

[0051] Reference Figure 2 If client 111 determines to trigger reconnection, trigger execution (214) of reconnection operation between terminal device 110 and network device 121.

[0052] Figure 3 An example of a reconnection operation between terminal device 110 and network device 121 is also specifically illustrated. For example... Figure 3 As shown, if client 111 determines to trigger reconnection, it can first disconnect (321) the communication connection with network device 121. After receiving the notification from client 111 that the communication connection has been disconnected, baseband transceiver 112 can first disconnect (322) the PDU / PDN connection, and then disconnect (323) the RRC connection between terminal device 110 and network device 121.

[0053] Furthermore, client 111 can re-establish (324) the communication connection between terminal device 110 and network device 121. Similarly, after receiving notification from client 111 to re-establish the communication connection, baseband transceiver 112 can re-establish (325) the PDU / PDN connection, and then establish (326) a new RRC connection between terminal device 110 and network device 121. Network device 121 reconfigures CDRX information based on the notification to establish a new RRC connection. And network device 121 can send the status of the reconfigured CDRX to (327) terminal device 110. Similarly, after receiving the status of the CDRX corresponding to the new RRC connection, baseband transceiver 112 sends the status of the CDRX to client 111 (328).

[0054] Network device 121 can re-determine whether to configure CDRX for terminal device 110 based on the new RRC connection established by terminal device 110. If terminal device 110 does not have a high data throughput data communication requirement at this time, network device 121 can configure CDRX for terminal device 110. In this case, the baseband transceiver 112 of terminal device 110 can notify client device 111 that CDRX is in the configuration state. Therefore, after receiving the CDRX status corresponding to the new RRC connection, client device 111 can determine (329) that CDRX is in the configuration state. In subsequent processes, terminal device 110 can continue to perform data transmission and reception with network device 121 in CDRX mode (330) and can save device power consumption.

[0055] As can be seen from the above embodiments, the embodiments of this disclosure can at least send the status of the CDRX of the terminal device 110 and the network device 121 to the terminal device 110. The terminal device 110 can start a detection process to determine whether to trigger a reconnection when it determines that the CDRX is in an unconfigured state. If the terminal device 110 detects that a reconnection should be triggered, it can trigger a reconnection operation between the terminal device 110 and the network device 121 to ensure that the CDRX of the terminal device 110 and the network device 121 is in a normal configuration state. This ensures that while the terminal device 110 and the network device 121 are performing normal data transmission and reception, the CDRX can be adjusted to enter a sleep state or a wake-up state based on the data transmission and reception status of the terminal device 110 and the network device 121, thereby reducing the power consumption of the terminal device 110 and extending the usage time of the terminal device 110.

[0056] Figure 5 A flowchart of an example process 500 for communication control according to some embodiments of the present disclosure is shown. Process 500 can be implemented at terminal device 110. Reference is made below. Figure 1 To describe process 500.

[0057] like Figure 5 As shown in block 510, terminal device 110 determines the state of connected discontinuous reception (CDRX) between terminal device and network device.

[0058] In box 520, terminal device 110, in response to a status indication that CDRX is in an unconfigured state, determines whether to trigger a reconnection based on at least one of the duration of the unconfigured state of CDRX and the data transmission and reception status of the terminal device.
