Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a method, a device, a collection device and a storage medium for collecting mobile terminal information.
Background
LTE (Long Term Evolution) is a Long Term Evolution of The UMTS (Universal Mobile Telecommunications System) technical standard established by The 3GPP (The 3rd Generation Partnership Project) organization, which was formally established and initiated at The 3GPP multi-toronto conference in 12 months in 2004.
At present, the existing LTE information acquisition device provides better cell signals than the public network, and can induce the terminal in the standby state to trigger cell reselection, and register the cell with the acquisition device, thereby completing the acquisition process. In order to satisfy the cell reselection threshold of the remote terminal and make the downlink coverage of the acquisition equipment wider, some technologies increase the downlink transmission power of the acquisition equipment.
However, according to the electromagnetic wave propagation theory, the farther the propagation distance, the greater the signal attenuation. Under the condition that the maximum transmitting power of the terminal is not changed, when an uplink signal transmitted by the terminal reaches the acquisition equipment after being transmitted in a long distance, the signal power is too low, and the signal-to-noise ratio does not reach a demodulation threshold, so that the demodulation fails. Therefore, when the uplink transmitting power of the terminal and the receiving sensitivity of the acquisition equipment are unchanged, the acquisition performance of the acquisition equipment cannot be improved and the acquisition range of the acquisition equipment cannot be enlarged by only increasing the downlink transmitting power of the acquisition equipment, and the success rate is low during remote acquisition.

Example one
Fig. 1 is a schematic flowchart of a method for acquiring mobile terminal information according to an embodiment of the present invention, which is applicable to a scenario of acquiring an IMSI of a mobile terminal, and the method may be executed by a device for acquiring mobile terminal information, and the device may be implemented in a software and/or hardware manner and may be integrated on an acquisition device.
As shown in fig. 1, a method for collecting information of a mobile terminal according to an embodiment of the present invention includes:
s110, controlling the mobile terminal to split the message packet with the established RRC connection into first data of a first piece and second data of a second piece.
The mobile terminal refers to a terminal into which a Subscriber Identity Module (SIM) card is inserted, and includes but is not limited to a mobile phone, an IPAD, and the like, and the specific mobile terminal is not limited herein. RRC is to perform radio resource management, control and scheduling by a certain policy and means, and make full use of limited radio network resources as much as possible to ensure that the radio network resources reach a planned coverage area and improve service capacity and resource utilization as much as possible while satisfying the requirement of service quality. The first slice refers to a carrier carrying first data and the second slice refers to a carrier carrying second data. Specifically, the second slice may be one slice, and may be a set of multiple slices (excluding the first slice). If the second slice is one slice, the second data is data of the second slice; if the second slice is a set of multiple slices (excluding the first slice), the second data may be a set on each slice of data in the multiple slices. In this embodiment, the second slice may be a set of multiple slices, that is, the data packet may be split into multiple slices of data, and is not limited to two slices. Preferably, the data packet is split into two pieces of data, i.e. the second piece is one piece.
The first data and the second data are part of data of the message packet, and the total data of the first data and the second data form the total data of the message packet. The size of the first data and the size of the second data are not particularly limited. Preferably, the first data size is smaller than the second data. Specifically, the size of the first data and the size of the second data are preconfigured and divided into the first data and the second data according to the preconfigured data information fragment.
Specifically, the packet data size of the message in this step is relatively large, and in order to realize that one message packet transmits all data, the MCS, RBNum, and TbSize need to be considered comprehensively. Taking 130 bytes of a data packet as an example, if transmission needs to be completed, according to the resource scheduling algorithm configuration table, MCS may be set to 5, RBNum to 15, and TBSize to 165 byte. Due to the fact that the transmitting power of the terminal is limited, when the RBNum is 15, the power of each RB is low, and when an uplink signal transmitted by the terminal reaches the acquisition device, the uplink signal does not reach a demodulation threshold corresponding to the MCS, and therefore successful demodulation cannot be achieved.
In this step, the message packet is split to perform multi-chip transmission, so that uplink resources required by each small chip are reduced, and when the total transmission power is not changed, the uplink signal power of each RB is increased, thereby solving the problem of demodulation failure caused by insufficient power on each RB during large packet transmission.
S120, allocating a first demodulation resource to the first data, and allocating a second demodulation resource to the second data.
The first demodulation resource refers to a resource for demodulating the first data. The second demodulation resource refers to a resource for demodulating the second data. Specifically, the first demodulation resource and the second demodulation resource may be configured in advance, and the demodulation resources do not need to be allocated adaptively. When demodulating, directly allocating a first demodulation resource and a second demodulation resource through the pre-configured demodulation resource information, and respectively demodulating the first data and the second data. The first demodulation resource is related to a size of the first data.
Optionally, the first demodulation resource includes a first RB number, a first MCS, and a first TBSize. Optionally, the second demodulation resource includes a second RB number, a second MCS, and a second TBSize. Optionally, the second RB number is not greater than the first RB number.
S130, demodulating the first data based on the first demodulation resource.
In this embodiment, the first data is demodulated by the preconfigured first demodulation resource, and since the size of the first data relative to the data packet is reduced, when the first data is demodulated based on the first demodulation resource, when the number of RBs is unchanged or smaller, the uplink signal power of each RB is increased, so that the success rate of demodulation is increased, and the success rate of information acquisition is increased.
S140, demodulating the second data based on the second demodulation resource.
In this embodiment, the second data is demodulated by the preconfigured second demodulation resource.
S150, sending an information acquisition request to the mobile terminal according to the successfully demodulated demodulation information of the first data and the second data.
The demodulation success information refers to information that the first data and the second data are successfully demodulated at the same time. Specifically, if the first data and the second data are successfully demodulated, it indicates that the data of the entire message packet has been transmitted to the acquisition device. The information acquisition request refers to a request for acquiring information of the mobile terminal. In this embodiment, the information acquisition request is an International Mobile Subscriber Identity (IMSI) acquisition request. The IMSI is an identification code that is not repeated in all cellular networks to distinguish different users in the cellular networks.
And S160, receiving the target information sent by the mobile terminal based on the information acquisition request.
The target information refers to information to be acquired in the information acquisition request. In this embodiment, the target information is the IMSI of the mobile terminal.
According to the technical scheme of the embodiment of the invention, the message packet which is established and completed by RRC connection is divided into the first data of a first piece and the second data of a second piece by controlling the mobile terminal; allocating a first demodulation resource to the first data, and allocating a second demodulation resource to the second data; demodulating the first data based on the first demodulation resources; demodulating the second data based on the second demodulation resource; sending an information acquisition request to the mobile terminal according to the successful demodulation information of the first data and the second data; and receiving the target information sent by the mobile terminal based on the information acquisition request, thereby achieving the technical effect of improving the success rate of successfully completing information acquisition when the uplink transmitting power of the terminal and the receiving sensitivity of the acquisition equipment are unchanged.
Example two
Fig. 2 is a flowchart illustrating a method for acquiring information of a mobile terminal according to a second embodiment of the present invention. The embodiment is further detailed in the technical scheme, and is suitable for a scene of collecting the IMSI of the mobile terminal. The method can be executed by a device for acquiring the information of the mobile terminal, and the device can be realized in a software and/or hardware mode and can be integrated on an acquisition device.
As shown in fig. 2, a method for acquiring information of a mobile terminal according to a second embodiment of the present invention includes:
s210, controlling the mobile terminal to split the message packet with the established RRC connection into first data of a first slice and second data of a second slice.
The mobile terminal is a terminal into which a Subscriber Identity Module (SIM) card is inserted, and includes but is not limited to a mobile phone, an IPAD, and the like, and the specific mobile terminal is not limited herein. The first slice refers to a carrier carrying first data and the second slice refers to a carrier carrying second data. The first data and the second data are part of data of the message packet, and the total data of the first data and the second data form the total data of the message packet. The size of the first data and the size of the second data are not particularly limited.
In this embodiment, the first data is valid data in the data packet, for example, data determining an access type, so as to be released to the mobile terminal subsequently. When the mobile terminal is released, the access type needs to be determined, so that a RELEASE request corresponding to the access type is sent out, and the mobile terminal is released. Optionally, the byte length of the first data is not less than the preset length threshold. The setting of the preset length threshold may be determined according to the access type. Specifically, the current access types include Attach access and Tau access, and the effective data lengths of different access types are different. Through the analysis of the bit code stream, the effective data length of the Attach access is found to be not more than 14 bytes; the effective data length of Tau access is 20 bytes. Therefore, on the premise that the access type is not clear, in order to ensure that demodulation can be successfully performed regardless of which access type, the preset length threshold is greater than the maximum value of valid data in the multiple access types, and the preset length threshold may be 20bytes or more, where a specific value of the preset length threshold is not limited. Preferably, the preset length threshold is 20 bytes.
S220, allocating a first demodulation resource to the first data, and allocating a second demodulation resource to the second data.
The first demodulation resource refers to a resource for demodulating the first data. The second demodulation resource refers to a resource for demodulating the second data. Specifically, the first demodulation resource and the second demodulation resource may be configured in advance, and the demodulation resources do not need to be allocated adaptively. When demodulating, directly allocating a first demodulation resource and a second demodulation resource through the pre-configured demodulation resource information, and respectively demodulating the first data and the second data. The first demodulation resource is related to a size of the first data.
S230, demodulating the first data based on the first demodulation resource.
In this embodiment, the first data is demodulated by the preconfigured first demodulation resource.
S240, demodulating the second data based on the second demodulation resource.
In this embodiment, the second data is demodulated by the preconfigured second demodulation resource.
Optionally, in order not to affect the acquisition flows of other mobile terminals, the second RB number of the second data does not exceed the first fragment. According to the AMC scheduling algorithm, when the length is a certain length, a higher second MCS and a smaller second RB number are adopted to carry the content of the second data, namely, the transmission of the second data is realized.
And S250, receiving a second demodulation failure message of the second data.
The second demodulation failure message is a message that the second data demodulation fails. Specifically, the first data is not less than the preset threshold, and when the first data is 20bytes, the byte length of the second data is relatively large. The second data may not be demodulated normally when the mobile terminal is moving at a high speed and away from the device, resulting in a failure in the transmission of the message packet.
S260, filling analog data corresponding to the second data based on the second demodulation failure message to generate the demodulation success message.
Specifically, since the first data includes valid data, the second data is invalid data, and the part of data is filled with the analog data, so that transmission of the message packet is completed, and thus the flow is executed next to complete information acquisition. The analog data is data that is simulated so that the second data can be normally transmitted. For example, when demodulation fails, a Cyclic Redundancy Check (CRC) error occurs, where CRC is a channel coding technique that generates a short fixed-bit Check code according to data such as a network data packet or a computer file, and is mainly used to detect or Check errors that may occur after data transmission or storage; the analog data is then padded with the correct CRC so that the second data transfer is complete.
In an optional embodiment, the second slice includes at least one FI indicator, and the padding analog data corresponding to the second data based on the second demodulation failure message includes:
receiving the FI indication identifier based on the second demodulation failure message;
and filling analog data corresponding to the second data based on the FI indication identification.
The FI (finish indication) indication mark is a mark for determining each piece of data, and the FI indication mark can determine which piece of data is carried. Specifically, when receiving a data packet sent by the mobile terminal, the device may indicate, at a data header (PDU Head) of the protocol data unit, an FI indicator of each slice. For example, for a PDU with only one slice, FI is 0b 00; for a multi-slice PDU, the FI of the first slice is 0b01, the middle slice is 0b11, and the last slice is 0b 10. And the equipment determines whether uplink resource authorization needs to be continuously carried out on the mobile phone according to the FI indication carried by each piece until all uplink data are transmitted.
S270, sending an information acquisition request to the mobile terminal according to the successfully demodulated demodulation information of the first data and the second data.
The demodulation success information refers to information that the first data and the second data are successfully demodulated at the same time. Specifically, if the first data and the second data are successfully demodulated, it indicates that the data of the entire message packet has been transmitted to the acquisition device. The information acquisition request refers to a request for acquiring information of the mobile terminal. In this embodiment, the information acquisition request is an International Mobile Subscriber Identity (IMSI) acquisition request. The IMSI is an identification code that is not repeated in all cellular networks to distinguish different users in the cellular networks.
And S280, receiving target information sent by the mobile terminal based on the information acquisition request.
The target information refers to information to be acquired in the information acquisition request. In this embodiment, the target information is the IMSI of the mobile terminal.
In an optional implementation manner, after demodulating the first data based on the first demodulation resource, the method may further include:
receiving a first demodulation failure message of the first data;
retransmitting the first data according to a hybrid automatic repeat request (HARQ) based on the first demodulation failure message.
The first demodulation failure message refers to a message that the first data demodulation fails. Specifically, since the first data includes valid data, the first data cannot be padded with analog data, and complete demodulation needs to be ensured for the first data. Therefore, when the first data demodulation fails to generate the first demodulation failure message, the first data needs to be retransmitted. And retransmitting when the first data demodulation fails so as to ensure the success rate of correct demodulation.
In another optional embodiment, after retransmitting the first data according to a hybrid automatic repeat request HARQ based on the first demodulation failure message, the method may further include:
judging whether the retransmission times are larger than a preset time threshold value or not;
and if the retransmission times are larger than the preset times threshold, terminating the acquisition process.
The preset number threshold is a criterion for determining whether to continue retransmission. The specific value of the preset number threshold is not limited. Preferably, the preset number threshold is 3. When the retransmission times are larger than the preset times threshold value, the demodulation is still not successful, if the range of the mobile terminal is too far away from the equipment and is not in the signal coverage range of the equipment, the acquisition process is terminated, and the long-term occupation of resources is avoided.
According to the technical scheme of the embodiment of the invention, the message packet which is established and completed by RRC connection is divided into the first data of a first piece and the second data of a second piece by controlling the mobile terminal; allocating a first demodulation resource to the first data, and allocating a second demodulation resource to the second data; demodulating the first data based on the first demodulation resources; demodulating the second data based on the second demodulation resource; sending an information acquisition request to the mobile terminal according to the successful demodulation information of the first data and the second data; and receiving the target information sent by the mobile terminal based on the information acquisition request, thereby achieving the technical effect of improving the success rate of successfully completing information acquisition when the uplink transmitting power of the terminal and the receiving sensitivity of the acquisition equipment are unchanged.
