The embodiment of the invention provides a message processing method and a message processing device, and finds that a modem with a small memory cannot realize the functions supported by an air interface message with a higher protocol version, because the radio resource control reconfiguration message has a large memory occupation in the air interface message with the higher protocol version, the modem cannot normally work due to the reset condition when decoding the received RRC reconfiguration message. Based on the discovery, in the embodiment of the invention, after the modem acquires the RRC reconfiguration message; the cell meeting the preset condition in the RRC reconfiguration message is cut, the memory occupation of the cut RRC reconfiguration message is reduced, so that when the cell is decoded according to the cut RRC reconfiguration message, the modems cannot be reset due to insufficient memory, namely, in the embodiment of the invention, some modems with smaller memory can support air interface messages with higher protocol version by cutting the RRC reconfiguration message, so that the modems with smaller memory do not need to be eliminated, and the energy is effectively saved.
The modem of the embodiment of the invention can be applied to communication between terminals, and the terminals can comprise: a mobile phone, a tablet computer, a notebook computer, a desktop computer or a server.
In general, if the protocol version of the third Generation Partnership Project (3 GPP) of the air interface message is higher, the air interface message is larger, and the message memory required to be applied when performing Abstract Syntax Notation (asn.1) coding and decoding on the larger air interface message is larger. I.e. air interface messages of higher protocol versions, require a modem with a larger memory as support. Therefore, in a general case, functions supported by a higher 3GPP protocol version air interface message cannot be implemented in a modem with a smaller memory, and an example modem with a smaller memory may include: the EM350 card uses a 3GPP R9 air interface protocol.
However, in specific applications, a scenario that a supplementary Uplink or full Uplink (SUL) function is implemented on a modem with a smaller memory often occurs, and the SUL function depends on a 3GPP R13 air interface protocol.
For example, in a specific implementation, the 3GPP R13 protocol supporting SUL may need to be migrated from a modem with a larger memory to an EM350-D35 card with a smaller memory, but the inventors found that after the migration is completed, a software version of the modem EM350-D35 is compiled and upgraded, and then the modem is reset, and an example air interface message flow table may be as shown in fig. 1. Due to the fact that the modem is reset, online logs are difficult to collect, and the reason for resetting the modem cannot be found through the online logs.
The inventors have further discovered in their research that when the modem is not brought into network, it is not reset. Therefore, further consider that when a modem is not networked, a HiStaudio (modem log tool) is connected to prepare to capture an online log, and then a radio frequency line is connected to enable the modem to be networked to observe whether the problem can be reproduced. However, since the log near the reset time point cannot be recorded in the log, the cause of the reset of the modem cannot be intuitively seen from the log.
In the further analysis of the log, it is found that each time the modem resets, after receiving the air interface RRC reconfiguration message, there is no abnormal printing at the corresponding time point in the log.
Based on this, in the embodiment of the present invention, a modem debug version is first compiled, and compared with an existing modem debug version, the modification of the modem debug version in the embodiment of the present invention includes: printing an RRC reconfiguration message size; the memory for storing the air interface message is not applied; asn.1 decoding is not performed on RRC reconfiguration messages.
Although the flow is abnormal (because the modem does not reply the RRC reconfiguration complete message to the base station, the base station timer sends an RRC release message to the modem after the timeout), the flow is not reset, and the size of the RRC reconfiguration message can be printed. Illustratively, as shown in fig. 2, the size of the printed RRC reconfiguration message is 79184 bytes.
And then the conclusion is obtained: since the RRC reconfiguration message is modified, SUL-related information elements are added, and the message becomes much larger. When the modem receives the RRC reconfiguration message, asn.1 decoding is performed first, and when applying for memory, the memory applied is large (79184 bytes as described above), resulting in insufficient memory left by the modem, thereby causing the modem to reset.
Based on the discovery, in the embodiment of the invention, after the modem acquires the RRC reconfiguration message; and cutting cells meeting preset conditions in the RRC reconfiguration message, wherein the memory occupation of the cut RRC reconfiguration message is reduced, so that the modem cannot be reset due to insufficient contents when decoding is carried out according to the cut RRC reconfiguration message.
As shown in fig. 3, fig. 3 is a flowchart illustrating a message processing method according to an embodiment of the present invention.
The method specifically comprises the following steps:
step S101: a radio resource control, RRC, reconfiguration message is received.
In the embodiment of the present invention, the modem may receive the RRC reconfiguration message sent by the network device such as the base station according to an actual application scenario, and specific content and specific role of the RRC reconfiguration message may be determined according to the actual application scenario, which is not specifically limited in the embodiment of the present invention.
Step S102: and cutting cells meeting preset conditions in the RRC reconfiguration message.
In the embodiment of the present invention, the cell which meets the preset condition in the RRC reconfiguration message may be specifically cut: and deleting the cell meeting the preset condition in the RRC reconfiguration message.
In the embodiment of the present invention, the step of cutting the cell meeting the preset condition in the RRC reconfiguration message may specifically be: and not decoding the cell meeting the preset condition in the RRC reconfiguration message.
It can be understood that, in a specific application, a person skilled in the art may also use other manners to cut the cell meeting the preset condition in the RRC reconfiguration message according to an actual application scenario, which is not specifically limited in this embodiment of the present invention.
In the embodiment of the present invention, the cells satisfying the preset condition may be cells which cannot be identified or are not required by the modem. The normal cell satisfying the predetermined condition may be a higher protocol version cell.
It can be understood that, in a specific application, a person skilled in the art may also set the preset condition according to an actual application scenario, and this is not specifically limited in the embodiment of the present invention.
For example, taking the RRC reconfiguration message as the C-language data structure, in the C-language data structure of the RRC reconfiguration message, the RRCConnectionReconfiguration-v1130-IEs data structure in the corresponding asn.1 in the 3GPP protocol 36.331 in the RRC reconfiguration message may be deleted, and the bit originally used in the C-language data structure to indicate whether the deleted data structure cell exists is not deleted.
In the C language data structure of the RRC reconfiguration message, all data structures from cross carrier scheduling config-r13 (included) to csi-RS-confign pzpdoreleaselist-r 13 (included) in the data structure of the physical config dedicatedcell-r 10 in asn.1 of the RRC reconfiguration message corresponding to 3GPP protocol 36.331 may also be deleted, and each bit in the C language data structure that was originally used to indicate whether these deleted data structure cells exist is not deleted.
After verification, as shown in fig. 4, after the RRC reconfiguration message is trimmed, the modem debugging version is compiled again, and the log-printed RRC reconfiguration message size is 37121 bytes, which is much smaller than the initial RRC reconfiguration message.
In summary, the embodiments of the present invention provide a method and an apparatus for message processing, which find that a modem with a smaller memory cannot implement a function supported by an air interface message with a higher protocol version, because the radio resource control reconfiguration message occupies a larger memory in the air interface message with the higher protocol version, so that when the modem decodes a received RRC reconfiguration message, the modem cannot normally operate due to a situation of resetting caused by insufficient memory. Based on the discovery, in the embodiment of the invention, after the modem acquires the RRC reconfiguration message; the cell meeting the preset condition in the RRC reconfiguration message is cut, the memory occupation of the cut RRC reconfiguration message is reduced, so that when the cell is decoded according to the cut RRC reconfiguration message, the modems cannot be reset due to insufficient memory, namely, in the embodiment of the invention, some modems with smaller memory can support air interface messages with higher protocol version by cutting the RRC reconfiguration message, so that the modems with smaller memory do not need to be eliminated, and the energy is effectively saved.
Optionally, on the basis of the embodiment corresponding to fig. 3, in the message processing method according to the embodiment of the present invention:
the cells meeting the preset conditions are as follows: a cell which is not supported by the communication version of the modem and is at the end of the code stream of the RRC reconfiguration message after being coded; or the like, or, alternatively,
the communication version of the modem does not support, and the plurality of cells are continuously positioned at the end of the code stream of the RRC reconfiguration message after being coded.
In the embodiment of the present invention, a cell that meets a preset condition may be referred to as an independent cell, and specifically, an independent cell refers to a cell of a higher protocol version, which is generally a cell that a corresponding modem software (i.e., a communication version, such as an air interface protocol) does not need to support the function of the cell.
In practical applications, the inventor further finds that, when the modem decodes the RRC reconfiguration message, it is necessary to decode the continuous RRC reconfiguration message, and if an interruption occurs in the RRC reconfiguration message, for example, a part of cells in the middle of the RRC reconfiguration message are clipped, the modem cannot correctly decode the clipped message content.
In a scenario where the RRC reconfiguration message carries multiple Secondary Cell (SCELL) configurations, if one of the SCELL configurations in the RRC reconfiguration message is trimmed, the other SCELL configurations may not be correctly encoded.
Therefore, the method of the embodiment of the present invention is applicable to a scenario in which the RRC reconfiguration message only carries one SCELL configuration, for example, a scenario in which the RRC reconfiguration message corresponds to that the structure array scelltoddmodlist-r 10 in asn.1 in the 3GPP protocol 36.331 only uses one structure array element, but is not applicable to a scenario in which multiple array elements are used.
In summary, the clipped cells have the following common points: the function of the clipped cell does not need to be supported on the software version of the corresponding modem; the stream of the downlink air interface message corresponding to all the deleted cells and having undergone the asn.1 coding must be continuously located at the end of the stream of the downlink air interface message having undergone the asn.1 coding.
That is, in a scenario where the RRC reconfiguration message only carries one Secondary Cell (SCELL) configuration, the cells meeting the preset condition are: a cell which is not supported by the communication version of the modem and is at the end of the code stream of the RRC reconfiguration message after being coded; or, the communication version of the modem does not support, and after being encoded, the modem is continuously located in a plurality of cells at the end of the code stream of the RRC reconfiguration message.
Optionally, the cutting the cell meeting the preset condition in the RRC reconfiguration message includes:
and in the process of decoding the RRC reconfiguration message, not decoding the cell meeting the preset condition in the RRC reconfiguration message.
In the embodiment of the invention, in the process of decoding the RRC reconfiguration message, the cell meeting the preset condition in the RRC reconfiguration message is not decoded, so that the effect of cutting the cell meeting the preset condition can be realized.
Optionally, the cutting the cell meeting the preset condition in the RRC reconfiguration message includes:
in the process of decoding the RRC reconfiguration message, matching each cell included in the RRC reconfiguration message with a preset irrelevant network element configuration table; the configuration table of the irrelevant network element comprises: cell identifiers of cells meeting the preset conditions; and not decoding the cell matched with the irrelevant cell configuration table in the cell identification in the RRC reconfiguration message.
In the embodiment of the invention, the cell identifier which is not supported by the modem can be arranged in an irrelevant cell configuration table, in the process of decoding the RRC reconfiguration message, the cell identifier of each cell can be matched with the cell identifier in the irrelevant cell configuration table, if the cell identifier in the RRC reconfiguration message is matched with the cell identifier in the irrelevant cell configuration table, the irrelevant cell can be considered to exist in the RRC reconfiguration message, and the irrelevant cell is not decoded, so that the effect of cutting the cell meeting the preset condition can be realized.
It can be understood that the irrelevant cell configuration table in the embodiment of the present invention is similar to the function of the blacklist, and in practical application, a whitelist corresponding to the irrelevant cell may also be set according to a practical application scenario, and the cell corresponding to the cell identifier in the whitelist is decoded, which is not specifically limited in the embodiment of the present invention.
Optionally, after the cell meeting the preset condition in the RRC reconfiguration message is trimmed, the method further includes:
and updating the irrelevant network element configuration table according to a preset rule.
In the embodiment of the present invention, it is considered that in practical applications, a protocol version of an RRC reconfiguration message is updated along with development of a communication technology, and an irrelevant cell of the RRC reconfiguration message is changed along with conversion of the protocol version, so that a specific preset rule may be determined according to an actual application scenario, and the irrelevant cell configuration table is updated, and a modem may support RRC reconfiguration messages of different protocol versions according to the updated irrelevant cell configuration table, so as to implement more applications of the modem.
In summary, the embodiments of the present invention provide a method and an apparatus for message processing, which find that a modem with a smaller memory cannot implement a function supported by an air interface message with a higher protocol version, because the radio resource control reconfiguration message occupies a larger memory in the air interface message with the higher protocol version, so that when the modem decodes a received RRC reconfiguration message, the modem cannot normally operate due to a situation of resetting caused by insufficient memory. Based on the discovery, in the embodiment of the invention, after the modem acquires the RRC reconfiguration message; the cell meeting the preset condition in the RRC reconfiguration message is cut, the memory occupation of the cut RRC reconfiguration message is reduced, so that when the cell is decoded according to the cut RRC reconfiguration message, the modems cannot be reset due to insufficient memory, namely, in the embodiment of the invention, some modems with smaller memory can support air interface messages with higher protocol version by cutting the RRC reconfiguration message, so that the modems with smaller memory do not need to be eliminated, and the energy is effectively saved.
