The terminal in fig. 1 may transmit data to the base station through the modem, or may receive data transmitted from the base station through the modem. In the related art, after a terminal receives Data through a modem, the terminal needs to store the received Data, wherein the terminal divides the received Data into two parts, and one part is description information (Data Tag) of the Data, and the description information is used for describing Payload Data (Payload Data) of the received Data. The current primary 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 obtained.
The process of transmitting application data to the base station in the terminal may be as follows: the terminal stores the application data to be sent in the DDR through the AP, encrypts the application data to be sent through an encryptor (Cipher), and after Integrity protection is carried out on the application data to be sent through an Integrity protector (Integrity), the application data processed through the Cipher and the Integrity is stored in an on-chip memory, and finally the application data is transmitted through a physical layer.
Referring to fig. 2, a schematic diagram of a structure of in-terminal storage data according to an exemplary embodiment of the present application is shown.

The life cycle of the first description information 201 is the same as that of the third description information 203, and 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 together in the 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 cycle, redundant searching and judging operations are introduced, for example, the situation that the first description information 201 and the third description information 203 are established and released for multiple times increases the complexity of managing the description information by the terminal, and reduces the management efficiency of data in the on-chip memory.
In order to improve the management efficiency of data storage in the terminal and expand the data storage manner in the terminal, the present application provides a solution, please refer to fig. 3, which shows a method flowchart of a data storage method 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 steps of:
in step 301, in response to receiving the first target data through the modem, a logical channel of the first target data and description information of the first target data are acquired.
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 the terminal receives the first target data through the modem, the terminal can acquire the logical channel for receiving the first target data, for example, the modem marks the logical channel for the received data according to the current working state of the modem, for example, the modem works in a state of receiving a CCCH (Common Control Channel ), and the modem marks the logical channel for the received data as a CCCH channel, so that the logical channel for the first target data can be acquired.
Alternatively, the description information of the first target data may be information that is created by the modem for the first target data and is used to describe payload information of the first target data.
Step 302, a first storage address is obtained according to a logical channel of the first target data.
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 acquire the 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.
In step 303, according to the first storage address, the description information of the first target data is stored in the first memory.
The modem stores the obtained description information of the first target data in the first memory according to the first storage address, so that the storage positions of the description information of the target data of the same logic channel in the first memory are the same, and the storage positions of the description information of the target data of different logic channels in the first memory are different. Alternatively, the first memory may be the on-chip memory described above, 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 memory 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 application can divide and store the description information of the first target data through the received logic channel, ensures 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, thereby avoiding the steps of searching and judging for multiple times caused by chaotic storage of description information of different periods, improving the management efficiency of data after data storage, reducing the calculation period of a processor in a modem, improving the utilization rate of the processor in the modem, and optimizing the performance of the processor in the modem.
In one possible implementation, the first memory is another memory different from the on-chip memory, and is used for storing description information of data received by the modem. The first memory is another memory different from the on-chip memory, and the terminal includes a second memory, which is an example of the on-chip memory. The scheme shown in fig. 3 is described by way of example.
Referring to fig. 4, a method flowchart of a data storage method according to an exemplary embodiment of the 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 steps of:
in step 401, in response to receiving the first target data through the modem, a logical channel of the first target data and description information of the first target data are acquired.
The description information is used for describing Payload data of the first target data. The first target data may be data within any logical channel received by the modem, for example, the first target data may be channel data of RLC (Radio Link Control, radio link control layer) or channel data of PDCP (Packet Data Convergence Protocol, packet data convergence protocol layer).
After receiving the first target data, the terminal may acquire the logical channel of the first target data and the description information of the first target data, and the acquiring manner may refer to the description in step 301 in the embodiment of fig. 3, which is not described herein again.
Step 402, obtaining the second storage address according to the order in which the first target data is received in each data.
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 is received. For example, a first storage area in a second memory in the terminal is idle, the terminal receives 3 target data sequentially, the description information of the first target data is stored from the 3 rd bit to the 8 th bit in the first storage area in the second memory, the description information of the first target data is stored from the 9 th bit to the 10 th bit in the first storage area in the second memory, the description information of the third target data is stored from the 11 th bit to the 15 th bit in the first storage area in the second memory, and so on, and the terminal can obtain the storage address of the description information in the second memory according to the receiving sequence of the first target data.
And step 403, storing the description information of the first target data into a second memory according to the second storage address.
Correspondingly, after obtaining the second storage address, the terminal stores the description information of the first target data into the second memory according to the second storage address.
Step 404, obtaining a first number, where the first number is the number of logical channels corresponding to the description information stored in the second memory.
Optionally, in the present application, the terminal may further actively acquire the number of each logical channel corresponding to the description information stored 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, and if yes, 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 number being greater than the number threshold, a first memory is started 405.
After judging that the first number is greater than the number threshold, the terminal can start the first memory. For example, the number threshold is 2, when the number of the logic channels corresponding to the description information stored in the second memory exceeds 2, the life cycle of the description information of each target data stored in the second memory is different, and the first memory is required to be started at this time, and the description information of the target data is stored according to the logic channels through the first memory, so that the description information of the target data of different logic channels is prevented from being stored in the same position.
Step 406, obtaining a first storage address according to the logical channel of the first target data, where the first storage address is a storage address of the description information of the first target data in the first memory.
Alternatively, the terminal may obtain 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 divided in the first memory in advance corresponding to different logic channels, and the terminal can acquire the first storage area in the first memory according to the corresponding relation between the logic channels and each storage area, wherein the first storage area is the storage area corresponding to the logic channels in the first memory; . Referring to table 1, a table of correspondence between logical channels and a storage area of a first memory according to an exemplary embodiment of the present application is shown.
| 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 a logical channel one, the storage area of the first target data corresponding to the first memory is a storage area one.
Optionally, the terminal acquires the first storage area in a logic channel according to the first target data, and generates the first storage address according to the first storage area. For example, the above-mentioned first storage area corresponds to 900 th to 40000 th bits of the first memory, and then the terminal may generate a first storage address for storing description information of the first target data according to the bits remaining in the area. That is, after the terminal obtains the first storage area, the terminal may generate a storage address for the first target data in the order of bits remaining in the first storage area.
In step 407, according to the first storage address, the description information of the first target data is stored into the first memory.
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 one 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 in the first memory from the second memory according to the first storage address; and releasing 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 into the first memory according to the first storage address generated as described above.
In one possible implementation, the modem in the terminal may further receive a data transfer instruction of the first processor, where the data transfer instruction is used to instruct to store the description information of the first target data from the second memory into the first memory; and storing the description information of the first target data from the second memory to the first memory according to the first storage address in response to the data transfer instruction. The first processor may be a baseband processor (Baseband Processor, BP).
That is, in the above-described process of starting the first memory, the terminal may also generate a data transfer instruction by 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, the step 401 may further be performed in the present application to obtain Payload data of the first target data 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, acquires the Payload data of the first target data at the same time of the above step 401, and stores the Payload data of the first target data in the DDR.
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 memory 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 application can divide and store the description information of the first target data through the received logic channel, ensures 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, thereby avoiding the steps of searching and judging for multiple times caused by chaotic storage of description information of different periods, improving the management efficiency of data after data storage, reducing the calculation period of a processor in a modem, improving the utilization rate of the processor in the modem, and optimizing the performance of the processor in the modem.
In addition, by 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 one possible implementation manner, the method embodiments of fig. 3 and fig. 4 are illustrated by taking the mobile phone as the terminal, and the first memory, the on-chip memory and the modem included in the mobile phone as examples. Referring to fig. 5, a method flowchart of a data storage method according to an exemplary embodiment of the application is shown. The method is carried out by a mobile phone in daily life, and as shown in fig. 5, the data storage method can comprise the following steps:
in step 501, in response to the modem receiving the first target data, description information and payload information of the first target data are acquired.
In step 502, the description information of the first target data is stored in an on-chip memory.
In step 503, a first number is obtained, the first number being the number of logical channels of the first target data stored in the on-chip memory.
In step 504, a first memory is started in response to the first number being greater than a number threshold.
In step 505, the description information of the first target data in the on-chip memory is stored into the first memory.
Step 506, storing the payload information of the first target data into the DDR.
Optionally, details of the execution of steps 501 to 506 may refer to the descriptions of the respective steps in fig. 4, which are not described herein.
Referring to fig. 6, a schematic diagram of a structure of data stored in a mobile phone according to an exemplary embodiment of the application is shown. As shown in fig. 6, the first description information 601, the second description information 602, and the third description information 603 are stored on the on-chip memory 600, and the first payload data 606, the second payload data 607, and the third payload data 608 are stored on the DDR 605. When the number of the logic channels of the first descriptive information 601, the second descriptive information 602 and the third descriptive information 603 is greater than the number threshold, the first memory 604 is started, the first descriptive information 601 and the second descriptive information 602 stored in the on-chip memory 600 are transferred to the first memory 604, and the third descriptive information 603 is distinguished and stored according to the logic channels of the descriptive information through 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 memory 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 application can divide and store the description information of the first target data through the received logic channel, ensures 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, thereby avoiding the steps of searching and judging for multiple times caused by chaotic storage of description information of different periods, improving the management efficiency of data after data storage, reducing the calculation period of a processor in a modem, improving the utilization rate of the processor in the modem, and optimizing the performance of the processor in the modem.
