Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technology, and in particular to a data transmission method and device, and a storage medium. Background Art

[0002] With the emergence of new 5G services, there is a demand for dual-SIM dual-data concurrency, such as RCS services.

[0003] To adapt to the coexistence of NSA / SA and the different frequency bands of 4G / 5G networks, dual-card terminals have multiple combinations such as 4G dual-card dual-LTE, 5G main card NSA + secondary card LTE or main card SA + secondary card LTE. Many terminals use TDM to multiplex the RF transmission channel to achieve dual-card dual-pass. If a dual-card terminal can support dual data services, there is a problem of RF resource preemption during concurrent use, which means that one of the card services has to be interrupted.

[0004] Currently, no terminal supports concurrent data services of two cards. Due to the suddenness and disorder of data services, when the data of two cards in the terminal are activated at the same time to occupy radio frequency resources, it is difficult for the terminal to ensure that the services of the two cards can obtain radio frequency resources in time to send and receive data, resulting in service interruption.

[0031] In response to the problem in the related art that it is difficult to ensure that the dual-card services can obtain radio frequency resources in time to send and receive data when the data of the two cards of the terminal device are activated simultaneously to seize radio frequency resources, the present disclosure provides a data transmission method for realizing dual-card dual-data service concurrency based on a dual-card terminal. When the dual-card terminal switches the radio frequency resources to one card, it monitors the link status of the other card at the same time, and switches the radio frequency resources back before the network determines that the link fails, so as to ensure that the RRC connection is not released, avoid service interruption, and realize dual-card dual data (RCS) service concurrency.

[0032] At least one embodiment of the present disclosure provides a data transmission method, which is executed by a terminal device. Figure 2 Another flow chart of the data transmission method in the embodiment of the present disclosure is shown. Figure 2 As shown, the method includes steps S200 and S201.

[0033] S200: The terminal device allocates uplink radio frequency resources to the first terminal card for data service transmission, and starts a first countdown timer corresponding to the second terminal card.

[0034] S201. During a time period when the first countdown timer returns to 0, the terminal device allocates uplink radio frequency resources to the second terminal card for data service transmission, and starts a second countdown timer corresponding to the first terminal card.

[0035] S202: During the time period when the second countdown timer returns to 0, the terminal device allocates uplink radio frequency resources to the first terminal card for data service transmission, and starts the first countdown timer corresponding to the second terminal card.

[0036] In an embodiment of the data transmission method disclosed in the present invention, the terminal device allocates uplink radio frequency resources to the first terminal card for data service transmission, and simultaneously starts the first countdown timer corresponding to the second terminal card to monitor the link status of the second terminal card, and within the time period when the first countdown timer returns to 0, the terminal device allocates uplink radio frequency resources to the second terminal card for data service transmission, that is, before the network determines that the link corresponding to the second terminal card has failed, the uplink radio frequency resources are switched to the second terminal card to ensure that the RRC connection of the second terminal card is not released, avoid service interruption, and realize dual-card dual-data (RCS) service concurrency.

[0037] At least one embodiment of the present disclosure provides a data transmission method, which is executed by a terminal device. Figure 3 Another flow chart of the data transmission method in the embodiment of the present disclosure is shown. Figure 3 As shown, the method includes steps S300 and S304.

[0038] S300: The terminal device determines to perform data transmission.

[0039] For example, the terminal devices need to perform data (eg, RCS) service transmissions separately.

[0040] S301. A terminal device establishes an RRC connection with a network corresponding to a first terminal card and a network corresponding to a second terminal card, respectively.

[0041] When the terminal device needs to perform data (eg, RCS) service transmission, it establishes an RRC connection with the network corresponding to the first terminal card and the network corresponding to the second terminal card.

[0042] S302, the terminal device determines whether the data services of the first terminal card and the second terminal card have TTI overlap. If the first terminal card and the second terminal card have TTI overlap, execute step S303; if the first terminal card and the second terminal card do not have TTI overlap, execute step S304.

[0043] During the T period when dual-card data (such as dual RCS) is concurrent, the terminal device determines whether there is TTI overlap in the transmission and reception of dual-card service data packets and whether there is competition for radio frequency resources. If there is no TTI overlap in the transmission and reception of dual-card service data packets, the terminal device processes the data service concurrency according to the predetermined plan. Otherwise, the terminal device preferentially allocates uplink radio frequency resources to the first terminal card, such as the primary card (card 1) to process the data service, and starts the countdown timer T2 (T2 <Timeout2)。

[0044] S303: Allocate uplink radio frequency resources to the first terminal card for data service transmission, and start a first countdown timer corresponding to the second terminal card.

[0045] When the RRC link layer uninterrupted threshold time of the data service of the second terminal card is less than the period of the timer configured by the network device for the second terminal card to control the data inactivity operation of the terminal device in the RRC_Connected state for controlling the data inactivity operation, the period of the first countdown timer is the threshold time of the RRC link layer uninterrupted threshold time of the data service of the second terminal card; and when the RRC link layer uninterrupted threshold time of the data service of the second terminal card is greater than the period of the timer configured by the network device for the second terminal card to control the data inactivity operation of the terminal device in the RRC_Connected state for controlling the data inactivity operation, the period of the first countdown timer is the period of the timer configured by the network device for the second terminal card to control the data inactivity operation of the terminal device in the RRC_Connected state.

[0046] Setting principle of counter Timeout2: The reference terminal selects the smaller of the threshold time Radiolink_Timeout2 for ensuring that the RRC link layer of the secondary card (Card 2) data service does not break - that is, no Radio Link Failure (RLF) event occurs and the period T_Timer2 of the timer dataInactivityTimer configured by the network for the terminal in the RRC_Connected state to control its data inactivity operation as the reference time Timeout2.

[0047] S304. The first terminal card and the second terminal card perform data service transmission in parallel.

[0048] S305. When the first countdown timer reaches 0, determine whether the data service transmission of the first terminal card has ended. If the data service transmission of the first terminal card has not ended, execute step S305; if the data service transmission of the first terminal card has ended, execute step S306.

[0049] S306. The terminal device allocates the uplink radio frequency resources to the second terminal card for data service transmission and starts the second countdown timer corresponding to the first terminal card.

[0050] When the threshold time for the RRC link layer of the data service of the first terminal card not to break is less than the period of the timer configured by the network device for the terminal device in the RRC_Connected state for the first terminal card to control its data inactivity operation, the period of the second countdown timer is the threshold time for the RRC link layer of the data service of the first terminal card not to break; and when the threshold time for the RRC link layer of the data service of the first terminal card not to break is greater than the period of the timer configured by the network device for the terminal device in the RRC_Connected state for the first terminal card to control its data inactivity operation, the period of the second countdown timer is the period of the timer configured by the network device for the terminal device in the RRC_Connected state for the first terminal card to control its data inactivity operation.

[0051] When T2 = 0 and the data service of the secondary card (Card 2) has not ended, the terminal allocates the uplink radio frequency resources to the secondary card (Card 2) to process the data service, and at the same time starts the main card (Card 1) countdown timer T1 (T1 < Timeout1). Setting principle of counter Timeout1: Select the smaller of Radiolink_Timeout1 and T_Timer1 as the reference time Timeout1.

[0052] S307. The terminal device allocates the uplink radio frequency resources to the second terminal card for data service transmission.

[0053] S308. When the second countdown timer is 0, determine whether the data service transmission of the second terminal card is completed. If the data service transmission of the second terminal card is not completed, the step returns to step S303; if the data service transmission of the second terminal card is completed, execute step S309.

[0054] S309: The terminal device allocates uplink radio frequency resources to the first terminal card for data service transmission.

[0055] It should be noted that the first terminal card and the second terminal card can be the main card and the secondary card of the terminal device, respectively. For example, the first terminal card is the main card and the second terminal card is the secondary card, or the first terminal card is the secondary card and the second terminal card is the main card. Before the network determines that the link corresponding to one of the first terminal card and the second terminal card fails, the uplink radio frequency resources are switched to the other of the first terminal card and the second terminal card until the data service transmission of one of the first terminal card and the second terminal card is completed. The terminal device switches the radio frequency resources between the dual cards to realize the concurrency of dual-card dual-data services, ensure the concurrency of dual-card services within a controllable and limited service delay, and improve the user experience.

[0056] In an embodiment of the data transmission method disclosed in the present invention, the terminal device allocates uplink radio frequency resources to the first terminal card for data service transmission, and simultaneously starts the first countdown timer corresponding to the second terminal card to monitor the link status of the second terminal card, and within the time period when the first countdown timer returns to 0, the terminal device allocates uplink radio frequency resources to the second terminal card for data service transmission, that is, before the network determines that the link corresponding to the second terminal card has failed, the uplink radio frequency resources are switched to the second terminal card to ensure that the RRC connection of the second terminal card is not released, avoid service interruption, and realize dual-card dual-data (RCS) service concurrency.

[0057] The data transmission method disclosed in the present invention is described in detail below in conjunction with the embodiments. The first terminal card is a primary card, and the second terminal card is a secondary card.

[0058] Step 1: The dual SIM cards of the terminal device need to perform data (such as RCS) services separately.

[0059] Step 2: The dual-SIM terminal device establishes RRC connections with two networks respectively.

[0060] Step 3: During the T period, check whether the dual-SIM data services of the terminal device have TTI overlap or compete for radio frequency resources.

[0061] Step 4: If there is no TTI overlap, the terminal device processes the dual-card data services in parallel. If there is TTI overlap, the terminal device preferentially allocates uplink radio frequency resources to the primary card (card 1) to process the data service, and starts the countdown timer T2 at the same time.

[0062] Step 5: Whenever T2=0, whether the data service of the primary card (card 1) is terminated within the T2 period.

[0063] Step 6: If the data service of the primary card (Card 1) ends, the dual-card terminal device allocates uplink radio frequency resources to the secondary card (Card 2) to process the data service. If the data service of the primary card (Card 1) has not ended, the terminal device allocates uplink radio frequency resources to the secondary card (Card 2) to process the data service, and starts the countdown timer T1 of the primary card (Card 1) at the same time.

[0064] Step 7: Whenever T1=0, whether the data service of the secondary card (Card 2) is terminated during the T1 period.

[0065] Step 8: If the data service of the secondary card (Card 2) ends, the dual-card terminal device allocates the uplink radio frequency resources to the primary card (Card 1) to process the data service. If the data service of the secondary card (Card 2) has not ended, the terminal device preferentially allocates the uplink radio frequency resources to the primary card (Card 1) to process the data service, and starts the countdown timer T2 at the same time.

[0066] The present disclosure proposes a data transmission method for realizing dual-card dual-data service concurrency based on a dual-card terminal, taking into account the threshold time Radiolink_Timeout of the terminal radio link failure (RLF) event and the period T_Timer of the timer dataInactivityTimer configured by the network for the terminal in the RRC_Connected state to control its data inactivity operation, and selecting a suitable radio resource switching period (T1 / T2) to realize dual-card data service concurrency, filling the gap that dual-channel terminals cannot perform dual-data service concurrency. The technical solution disclosed in the present disclosure will greatly improve the dual-card terminal's ability to support dual-card data service concurrency, improve the terminal's dual-channel performance, and improve network transmission efficiency.

[0067] The concurrency of dual-SIM dual-data services is the evolution direction of dual-SIM terminals. The disclosed technical solution will help the industry chain to promote dual-pass technology research, verification and standardization for 5G dual-SIM terminals, improve NR network system performance and enhance user experience.
