Referring to fig. 1, a schematic structural diagram of a wireless communication system according to an exemplary embodiment of the present application is shown. As shown in fig. 1, the wireless communication system is a communication system based on a cellular mobile communication technology, and may include: several terminals 110 and base stations 120.

For example, a Station (STA), a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile), a Remote Station (Remote Station), an Access point, a Remote Terminal (Remote Terminal), an Access Terminal (Access Terminal), a User Equipment (User Terminal), a User agent (User agent), a User Equipment (User Device), or a User Terminal (UE). Alternatively, the terminal 110 may be a device of an unmanned aerial vehicle, a vehicle-mounted device, or the like.
The base station 120 may be a network device in a wireless communication system. The wireless communication system may also be a 5G system, which is also called a New Radio (NR) system. Alternatively, the wireless communication system may be a next-generation system of a 5G system.
Optionally, the base station 120 may be a base station (gNB) adopting a centralized distributed architecture in the 5G system. When the base station 120 employs a centralized Distributed architecture, it typically includes a Central Unit (CU) and at least two Distributed Units (DU). A Packet Data Convergence Protocol (PDCP) layer, a Radio Link layer Control Protocol (RLC) layer, and a Media Access Control (MAC) layer are set in the central unit; a Physical (PHY) layer protocol stack is disposed in the distribution unit, and the embodiment of the present application does not limit the specific implementation manner of the base station 120.
The base station 120 and the terminal 110 may establish a radio connection over a radio air interface. In different embodiments, the wireless air interface is a wireless air interface based on a fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; alternatively, the wireless air interface may be a wireless air interface based on a 5G next generation mobile communication network technology standard.

The embodiment of the present application is not limited to the implementation form of the network management device 130.
The terminal in fig. 1 may transmit data to the base station through a modem, or may receive data transmitted by the base station through the modem. In the related art, after receiving Data through a modem, a terminal needs to store the received Data, wherein the terminal divides the received Data into two parts, one part is Data Tag (Data Tag) for describing payload Data (payload Data) of the received Data. The current major data storage schemes are: when the 5G modem receives the data, the payload part of the data is stored in the DDR, the description part of the data is stored in the on-chip memory, and when the data needs to be acquired, the two parts of data can be combined through the corresponding relation between the description information stored in the on-chip memory and the payload part in the DDR, so that the data is acquired.
The procedure of transmitting the application data to the base station in the terminal may be as follows: the terminal stores application data to be sent in a DDR through an AP, encrypts the application data to be sent through an encryptor (Cipher), performs Integrity protection on the application data to be sent through an Integrity protector (Integrity), stores the application data processed through the Cipher and the Integrity in an on-chip memory, and finally transmits the application data through a physical layer.
Referring to fig. 2, a schematic structural diagram of data stored in a terminal according to an exemplary embodiment of the present application is shown. As shown in fig. 2, first description information 201, second description information 202, and third description information 203 are stored On an On Chip Memory 200 of the terminal, and first payload data 205, second payload data 206, and third payload data 207 are stored On a DDR204 of the terminal. Wherein the first description information 201 is used to describe the first payload data 205, the second description information 202 is used to describe the second payload data 206, and the third description information 203 is used to describe the third payload data 207.
The life cycles of the first description information 201 and the third description information 203 are the same, the life cycle of the second description information 202 is greater than that of the first description information 201 and the third description information 203, if the first description information 201, the second description information 202 and the third description information 203 are stored in an on-chip memory, when the first description information 201, the second description information 202 and the third description information 203 are released, the description information needs to be screened according to the life cycles, and redundant searching and judging operations are introduced, for example, when the first description information 201 and the third description information 203 are established and released for multiple times, the complexity of terminal management on the description information is increased, and the management efficiency of data in the on-chip memory is reduced.
In order to improve the management efficiency of data after the data is stored in the terminal and extend the way of storing the data in the terminal, the present application provides a solution, please refer to fig. 3, which shows a flowchart of a method for storing data according to an exemplary embodiment of the present application. The method can be applied to the terminal with the data receiving function shown in fig. 1. As shown in fig. 3, the data storage method may include the following steps:
The description information is used for describing Payload data of the first target data.
Alternatively, the first target data may be any set of data received by the modem. In the application, after receiving the first target data through the modem, the terminal may obtain a logical Channel that receives the first target data, for example, the modem marks the logical Channel for the received data according to its current operating state, for example, the modem operates in a state of receiving a Common Control Channel (CCCH), and the modem marks the logical Channel for the received data as the CCCH Channel, so as to obtain the logical Channel for the first target data.
Optionally, the description information of the first target data may also be information that is established by the modem for the first target data and used for describing payload information of the first target data.
Wherein the first storage address is a storage address of the description information of the first target data in the first memory. That is, the modem may obtain a storage address of the description information of the first target data in the first memory according to the logical channel of the first target data.
The modem stores the obtained description information of the first target data in a first memory according to the first storage address, so that the storage positions of the description information of the target data of the same logical channel in the first memory are the same, and the storage positions of the description information of the target data of different logical channels in the first memory are different. Alternatively, the first memory may be the above-mentioned on-chip memory, or may be a separately provided memory for storing description information of data.
In summary, after the modem in the terminal receives the first target data, the terminal may obtain the logical channel of the first target data and the description information of the first target data according to the first target data, obtain the storage address of the description information of the first target data in the first storage according to the logical channel of the first target data, and store the description information of the first target data according to the obtained storage address. The method and the device can divide and store the description information of the first target data through the received logic channels, ensure that the description information of the same logic channel is in the same storage position and the description information of different logic channels is in different storage positions, avoid multiple searching and judging steps caused by chaotic storage of the description information of different periods, improve the management efficiency of data after data storage, and reduce the calculation period of the processor in the modem, thereby improving the utilization rate of the processor in the modem and optimizing the performance of the processor in the modem.
In a possible implementation manner, the first memory is another memory different from the on-chip memory, and the first memory is used for storing description information of data received by the modem. For example, the first memory is another memory different from the on-chip memory, and the terminal includes a second memory, which is the on-chip memory. The above-described scheme shown in fig. 3 is described by way of example.
Referring to fig. 4, a flowchart of a method of storing data provided by an exemplary embodiment of the present application is shown. The method can be applied to the terminal with the data receiving function shown in fig. 1. As shown in fig. 4, the data storage method may include the following steps:
The description information is used for describing Payload data of the first target data. The first target Data may be Data in any logical channel received by the modem, for example, the first target Data may be channel Data of RLC (radio link Control) or PDCP (Packet Data convergence protocol).
After receiving the first target data, the terminal may obtain the logical channel of the first target data and the description information of the first target data, where the obtaining manner may refer to the description in step 301 in the embodiment in fig. 3, and details are not described here.
Wherein the second storage address is a storage address of the description information of the first target data in the second memory.
That is, the terminal acquires the storage addresses of the respective data in the second memory in the order in which the respective data in the first target data are received. For example, a first storage area in a second memory in the terminal is free, the terminal receives 3 pieces of target data in sequence, description information of the first piece of target data is stored in bits from 3 rd to 8 th in the first storage area in the second memory, description information of the first piece of target data is stored in bits from 9 th to 10 th in the first storage area in the second memory, description information of the third piece of target data is stored in bits from 11 th to 15 th in the first storage area in the second memory, and so on, the terminal can obtain storage addresses of the description information in the second memory according to the receiving sequence of the first piece of target data.
And step 403, storing the description information of the first target data into a second memory according to the second memory address.
Correspondingly, after the terminal obtains the second storage address, the terminal stores the description information of the first target data into the second storage according to the second storage address.
In step 404, a first number is obtained, where the first number is the number of each logical channel corresponding to the description information stored in the second memory.
Optionally, in this application, the terminal may further actively obtain the number of each logical channel corresponding to the stored description information in the second memory, count the number of each logical channel corresponding to the stored description information, and determine whether to start the first memory according to the first number, where the first memory is used in the terminal to store the description information of each first target data according to the logical channel. The terminal may determine whether the first number is greater than the number threshold, if so, execute step 404, otherwise, the terminal continues to store the description information of the first target data in the second memory according to the above scheme.
In response to the first quantity being greater than the quantity threshold, the first memory is activated, step 405.
The terminal may start the first memory after judging that the first number is greater than the number threshold. For example, the number threshold is 2, and when the number of each logical channel corresponding to the description information stored in the second memory exceeds 2, it indicates that the life cycles of the description information of each target data stored in the second memory are different, at this time, the first memory needs to be started, and the description information of the target data is stored according to the logical channels by the first memory, so that the description information of the target data of different logical channels is prevented from being stored in the same location.
Alternatively, the terminal may acquire the storage address in the first memory according to the logical channel of the first target data. In a possible implementation manner, different storage areas are previously divided in the first storage corresponding to different logical channels, and the terminal may obtain the first storage area in the first storage according to a correspondence between the logical channel and each storage area, where the first storage area is a storage area corresponding to the logical channel in the first storage; . Please refer to table 1, which shows a table of correspondence between logical channels and storage areas of the first memory according to an exemplary embodiment of the present application.
| Logical channel | First memory |
| Logical channel one | Storage area one |
| Logical channel two | Storage area two |
| Logical channel three | Storage area three |
| …… | …… |
TABLE 1
As shown in table 1, if the logical channel of the first target data is logical channel one, the storage area of the first target data in the first memory is storage area one.
Optionally, the terminal acquires the first storage area in the logical channel according to the first target data, and generates the first storage address according to the first storage area. For example, the first memory area corresponds to bits 900 to 40000 of the first memory, and the terminal may generate the first memory address for storing the description information of the first target data according to the remaining bits in the area. That is, after the terminal obtains the first storage area, it may generate a storage address for the first target data in the order of the remaining bits in the first storage area.
That is, the terminal may store the description information of the first target data in the first memory in accordance with the first storage address.
In a possible implementation manner, since the description information of the first target data is stored in the second memory, the terminal may store the description information of the first target data from the second memory into the first memory according to the first storage address; and releases the description information of the first target data stored in the second memory. That is, the terminal may acquire the description information of the first target data from the second memory and store the description information of the first target data in the first memory according to the first storage address generated as described above.
In a possible implementation manner, the modem in the terminal may further receive a data transfer instruction of the first processor, the data transfer instruction being used for instructing to store description information of the first target data from the second memory into the first memory; and in response to the data transfer instruction, storing the description information of the first target data from the second memory into the first memory according to the first memory address. The first Processor may be a Baseband Processor (BP).
That is, in the process of starting the first memory, the terminal may also generate a data transfer instruction through the first processor, so that the modem may store the description information of the first target data from the second memory into the first memory in response to the data transfer instruction.
Optionally, in this application, when the step 401 is executed, Payload data of the first target data may also be obtained in response to receiving the first target data. And storing Payload data of the first target data into the DDR.
That is, the present embodiment also stores the Payload data of the first target data, and obtains the Payload data of the first target data and stores the Payload data of the first target data in the DDR at the same time as the step 401.
In summary, after the modem in the terminal receives the first target data, the terminal may obtain the logical channel of the first target data and the description information of the first target data according to the first target data, obtain the storage address of the description information of the first target data in the first storage according to the logical channel of the first target data, and store the description information of the first target data according to the obtained storage address. The method and the device can divide and store the description information of the first target data through the received logic channels, ensure that the description information of the same logic channel is in the same storage position and the description information of different logic channels is in different storage positions, avoid multiple searching and judging steps caused by chaotic storage of the description information of different periods, improve the management efficiency of data after data storage, and reduce the calculation period of the processor in the modem, thereby improving the utilization rate of the processor in the modem and optimizing the performance of the processor in the modem.
In addition, by means of independently setting the first memory, the data request amount of the on-chip memory in the terminal can be reduced, and the acquisition efficiency and the management efficiency of the first target data are improved.
In a possible implementation manner, the method embodiments of fig. 3 and fig. 4 are illustrated by taking the terminal as a mobile phone, and taking the first memory, the on-chip memory and the modem included in the mobile phone as an example. Referring to fig. 5, a flowchart of a method of storing data provided by an exemplary embodiment of the present application is shown. The method is executed by a mobile phone in daily life, and as shown in fig. 5, the data storage method may include the following steps:
In step 503, a first number is obtained, where the first number is the number of logical channels of the first target data stored in the on-chip memory.
In response to the first quantity being greater than the quantity threshold, a first memory is activated, step 504.
Optionally, details of the steps 501 to 506 may refer to the description of each step in fig. 4, and are not described herein again.
Please refer to fig. 6, which shows a schematic structural diagram of data stored in a mobile phone according to an exemplary embodiment of the present application. As shown in fig. 6, first description information 601, second description information 602, and third description information 603 are stored on the on-chip memory 600, and first payload data 606, second payload data 607, and third payload data 608 are stored on the DDR 605. When the number of logical channels of the first description information 601, the second description information 602, and the third description information 603 is greater than the number threshold, the first memory 604 is activated, and the first description information 601, the second description information 602, and the third description information 603 stored in the on-chip memory 600 are transferred to the first memory 604, and are distinguished and stored according to the logical channels of the respective description information by the first memory.
In summary, after the modem in the terminal receives the first target data, the terminal may obtain the logical channel of the first target data and the description information of the first target data according to the first target data, obtain the storage address of the description information of the first target data in the first storage according to the logical channel of the first target data, and store the description information of the first target data according to the obtained storage address.
