Description
Technical Field
The present application relates to the field of wireless communications, and in particular, to a data processing method, apparatus, device, and storage medium.
Background
In the 5G network, the UE in the radio resource control INACTIVE state (RRC-INACTIVE) means that the UE maintains a CONNECTED mode (CM-CONNECTED) and can move within the notification area configured by the radio access network without notifying the base station. And the base station which has performed service with the UE in the notification area last time stores the context information of the UE and keeps the connection with the core network.
When the UE recovers the communication connection with the base station side, the UE needs to inform the base station side of its own id information, so that the base station side can quickly find the context information of the UE and the connection with the core network. This identity information is the inactive radio network temporary identity (I-RNTI). The third generation partnership project (3GPP) specifies two types of I-RNTIs, one being a full length I-RNTI, a 40-bit binary string; the other is a short I-RNTI, a 24-bit length binary string. The two types of I-RNTIs are formed by two parts, namely a user equipment identifier and a base station identifier, wherein the user equipment identifier is used for distinguishing different user equipment in the base station, and the base station identifier is used for distinguishing different base stations. When the context information of a certain user equipment cannot be found in the base station, a request needs to be sent to the base station where the user equipment is originally located according to the base station identifier in the I-RNTI of the user equipment to obtain the context information of the user equipment.
The number of bits of the base station identifier specified by 3GPP is 32 bits, and generally, only the full-length I-RNTI can be used to identify the context information of the user equipment, the number of bits reserved for the user equipment identifier is only 8 bits, the number of user equipment capable of being identified can reach up to 128, the number of UEs which can be served by one base station in an actual network mostly reaches thousands, the number of the existing user equipment identifiers cannot meet the requirement of the user equipment identifier, and therefore, a more practical and effective technical scheme needs to be provided.

A data processing method provided in the embodiment of the present application is described below, and fig. 2 is a schematic flow chart of the data processing method provided in the embodiment of the present application. It is noted that the present specification provides the method steps as described in the examples or flowcharts, but may include more or less steps based on routine or non-inventive labor. The order of steps recited in the embodiments is merely one manner of performing the steps in a multitude of orders and does not represent the only order of execution.

Specifically, as shown in fig. 2, the method may include:
s201, acquiring the same high-order identification among the base station identifications of a plurality of base stations in the current wireless access network.
In practical application, the current wireless access network is usually a 5G wireless access network, each base station in the 5G wireless access network has its own base station identifier, the base station identifier is usually a binary string with a fixed length, optionally, the base station identifier may be a 32-bit binary string, and the same high-order identifier, i.e., high-order code, of the base station identifiers of different base stations in the same 5G wireless access network is generally the same.

Specifically, the same high-level identifier between identifiers of base stations may be preset in the background, and the background sends a configuration instruction carrying the same high-level identifier to the base station, so that the base station sets the same high-level identifier.
For example, when the configuration range of the base station identifier in the current radio access network is 0x 00690001-0 x00698001, the same high-order identifier preset in the background is 0x 00690000.
And S303, storing the same high-order mark in a database of the current base station.
As can be seen from the above embodiments, the present application may send the preset same high-order identifier to the base station through the background, so as to split the identifier of the base station.
In a specific embodiment, as shown in fig. 4, fig. 4 is a flowchart illustrating a method for acquiring the same high-order identifier between base station identifiers according to an embodiment of the present disclosure, specifically, when the base stations in the current radio access network are connected through a preset interface, the method for acquiring the same high-order identifier may include:
s401, obtaining the base station identifications of the base stations.
In practical application, when the scale of the radio access network is small, the base stations in the network may be connected through a preset interface, and the base station identifiers of the plurality of base stations may be obtained from an interface neighbor list in the radio access network, and optionally, the preset interface may include an Xn interface.
And S403, performing XOR operation on any two base station identifiers in the base station identifiers of the plurality of base stations to obtain a plurality of identifier XOR data.
Specifically, the identifier xor data between different base station identifiers can be obtained through xor operation.
S405, target identification XOR data is obtained from the plurality of identification XOR data, and the target identification XOR data is the identification XOR data with the highest number of bits in the plurality of identification XOR data.
S407, determining the positions of the different low-order identifiers and the positions of the same high-order identifiers among the base station identifiers of the plurality of base stations according to the target identifier XOR data.
Specifically, the location bit of the target identifier xor data is used as the location bit of the difference lower identifier, and the location bits of the other identifiers except the difference lower identifier in the base station identifier are used as the location bits of the same higher identifier.
And S409, taking 1 as the position of the same high-order mark, and taking 0 as the position of the different low-order mark to obtain a high-order mask.
S411, performing a bitwise and operation on the high bit mask and any one of the base station identifiers of the plurality of base stations to obtain the same high bit identifier.
For example, there are 3 base stations in a small radio access network, where 3 base stations are connected through an Xn interface, and the base station identifiers of the 3 base stations are 0x00000001, 0x00000002, and 0x00000003, respectively;
carrying out XOR operation on any two base station identifications in the 3 base station identifications to obtain 3 identification XOR data which are respectively as follows:
0x00000001∧0x00000002＝0x00000003，
0x00000001∧0x00000003＝0x00000002，
0x00000002∧0x00000003＝0x00000001；
obtaining target identification exclusive-or data 0x00000003, namely 0b11 from the 3 identification exclusive-or data, and omitting 0 before the highest bit 1;
according to the target identification XOR data, determining that the position of the difference low-order identification is the 1 st to 2 nd bits of the binary system, and the position of the same high-order identification is the 3 rd to 32 nd bits of the binary system;
taking 1 as the position of the same high-order mark, and taking 0 as the position of the different low-order mark to obtain a high-order mask 0b 11111111111111111111111111111111111111111100;
and carrying out bitwise AND operation on the high-order mask and any base station identifier in the 3 base station identifiers to obtain the same high-order identifier 0x 00000000.
S203, acquiring the base station identification of the current base station.
S205, removing the same high-order mark from the base station mark of the current base station to obtain the short base station mark of the current base station.
In a specific embodiment, as shown in fig. 5, fig. 5 is a flowchart illustrating a method for generating a short base station identifier of a current base station according to an embodiment of the present disclosure, which may specifically include:
s501, determining the positions of the different low-order identifiers among the base station identifiers of the plurality of base stations according to the positions of the same high-order identifier.
In practical application, the length of the base station identifier is generally fixed, and the bits of other identifiers except the same high-order identifier in the base station identifier are used as the bits of the different low-order identifiers.
S503, the position of the same high-order mark is taken as 0, and the position of the different low-order mark is taken as 1, so as to obtain a low-order mask.
And S505, performing bitwise AND operation on the low bit mask and the base station identifier of the current base station to obtain the short base station identifier of the current base station.
For example, the base station id of the current base station is 0x00691001, and the same high bit id between the base station ids is 0x00690000, the bit where the difference low bit id is located is the 1 st to 4 th bits of hexadecimal, i.e. the 1 st to 16 th bits of binary, and the bit where the same high bit id is located is the 5 th to 8 th bits of hexadecimal, i.e. the 17 th to 32 th bits of binary.
The bit with the difference low bit identification is taken as 1, and the bit with the same high bit identification is taken as 0, resulting in the low bit mask 0b 0000000000001111111111111111, i.e. 0x0000 FFFF.
And performing bitwise AND operation on the low bit mask and the base station identifier of the current base station, namely 0x00691001&0x0000FFFF is 0x00001001 is 0x1001, and obtaining the short base station identifier of the current base station as 0x 1001.
It can be seen from the above embodiments that the base station short identifier can be obtained by removing the same high bits in the base station identifier, thereby increasing the number of bits of the initial device identifier and increasing the number of user devices that can be identified.
And S207, determining the number of the initial equipment identification bits based on the preset identification upper limit number of bits and the number of the bits of the short base station identification.
Specifically, the method for determining the number of identification bits of the initial device may include: and taking the difference between the preset identification upper limit digit and the digit of the short base station identification as the initial equipment identification digit.
Specifically, the difference between the numbers of bits may be a difference between binary numbers of bits.
In practical application, the preset identifier upper limit digit may be an upper limit digit of a Radio Network Temporary Identifier (RNTI) in a Radio access Network, specifically, the Radio Network temporary identifier may include an inactive Radio Network temporary identifier (I-RNTI), the I-RNTI may include a short I-RNTI and a full length I-RNTI, both I-RNTIs may be composed of a user equipment identifier and a base station identifier, and in this specification embodiment, both I-RNTIs may be composed of an initial device identifier digit and a base station short identifier.
In a specific embodiment, as shown in fig. 6, when the preset identifier upper limit bit number includes a preset short identifier upper limit bit number and a preset long identifier upper limit bit number, the taking a difference between the preset identifier upper limit bit number and the short base station identifier bit number as the initial device identifier bit number may include:
s601, calculating the bit number difference between the preset short identification upper limit bit number and the short base station identification bit number.
Specifically, the preset short identity upper limit digit may be an upper limit digit of a short I-RNTI, the short I-RNTI is usually a 24-bit binary character string, and the digit difference may be a binary digit difference.
S603, determining the maximum identification number corresponding to the digit difference.
Specifically, according to the binary digit difference, the power of the digit difference of 2 is used as the maximum identification number.
S605, determining whether the maximum identification number is greater than the maximum device support number of the current radio access network.
In practical applications, when the radio access network supports the access of the user equipment, an upper limit value of the number of the user equipment exists, and the upper limit value is used as the maximum equipment support number.
And S607, when the judgment result is yes, taking the digit difference as the initial equipment identification digit.
And S609, when the judgment result is negative, taking the difference between the preset long identification upper limit digit and the digit of the short base station identification as the initial equipment identification digit.
Specifically, when the maximum identification number corresponding to the difference between the preset short identification upper limit digit and the digit number of the short base station identification is smaller than the maximum equipment support number, the difference between the preset long identification upper limit digit and the digit number of the short base station identification is used as the initial equipment identification digit. The preset upper limit number of the long identifier may be the upper limit number of the full-length I-RNTI, and the length I-RNTI is usually a 40-bit binary string.
Specifically, the difference between the preset upper limit number of bits of the long flag and the number of bits of the short base station flag may be a binary number difference.
For example, the base station short identifier of the current base station is 0x1001, the corresponding hexadecimal digit number is 4 bits, the corresponding binary digit number is 16 bits, and the maximum device support number of the current radio access network is 3500;
presetting the bit number difference between the short identification upper limit bit number and the short base station identification bit number to be 24-16-8 bits;
the maximum identification number corresponding to the bit number difference is 28256, that is, the maximum number of users that the above bit number difference can identify is 256;
because 256 is less than 3500, that is, the maximum identification number is less than the maximum device support number of the current radio access network, the difference between the preset long identifier upper limit digit and the digit of the short base station identifier is used as the initial device identification digit, that is, the initial device identification digit is 40-16 to 24 digits, and the maximum identification number corresponding to the initial device identification digit is 22416777216, the identification requirement of the device in the current wireless access network can be satisfied.
By using the technical scheme of the embodiment, the initial equipment short identifier can be used when the maximum equipment support number of the current radio access network is small, and the initial equipment long identifier can be used when the maximum equipment support number is large, so that the length of the initial equipment identifier is reduced as far as possible under the condition of meeting the identification requirement of user equipment, the length of the I-RNTI is reduced, and the signaling overhead in the communication process is saved.
And S209, generating an initial device identifier corresponding to the first target device according to the number of the initial device identifier bits.
In practical application, the first target device may be a user device in an inactive state in a current radio access network, and a last service object of the first target device in a notification area of the current radio access network is the current base station.
Specifically, determining the coding range of the initial equipment identifier according to the number of bits of the initial equipment identifier; and selecting a target identifier from the coding range as an initial device identifier corresponding to the first target device, wherein the target identifier is an identifier which is not used in the coding range.
For example, if the number of bits of the initial device identifier is 24 bits, the encoding range of the initial device identifier is 0b00 … … 000(24 bits 0) -0 b111 … … 111(24 bits 1), i.e., 0x 000000-0 xfffffff, and one target identifier 0x001011 is selected from the encoding range as the initial device identifier corresponding to the first target device.
S211, generating first target device identification information based on the initial device identification and the short base station identification.
Specifically, the first target device identification information may be an RNTI of the first target device, and the RNTI may include an I-RNTI.
In a specific embodiment, the number of bits n of the short base station identifier may be determined, the initial device identifier of the first target device is shifted to the left by n bits, and the initial device identifier of the first target device after the left shift is added to the short base station identifier to obtain the first target device identifier information. For example, the initial device identifier of the first target device is 0x001011, the short base station identifier is 0x1001, the initial device identifier of the first target device after the left shift is 0x0010110000, and correspondingly, the first target device identifier information is 0x 0010111001.
S213, sending the first target device identification information to the first target device.
In practical application, when the first target device is in an inactive state, the I-RNTI of the first target device is sent to the first target device, so that when the first target device recovers communication connection with the base station side, the base station side is informed of own identification information by using the I-RNTI, and the base station side can quickly find context information of the first target device and connection with a core network.
It can be seen from the above embodiments that the same high-order identifier between base station identifiers can be obtained, and the same high-order identifier in the base station identifier of the current base station is removed, so that the number of bits of the base station identifier is reduced, the number of bits of the initial equipment identifier is increased, and the identifier requirement of the user equipment is met while the normal distinguishing function of the base station identifier is not influenced.
In an embodiment of this specification, as shown in fig. 7, fig. 7 is a flowchart illustrating a method for restoring context information of a target device, which may specifically include:
and S701, receiving a service recovery request sent by a second target device, wherein the service recovery request includes second target device identification information, and the second target device is any user equipment in the current wireless access network.
In practical application, when the second target device in the inactive state needs to recover the communication connection with the base station side, a service recovery request may be sent to the current base station, where the service recovery request may be a Radio Resource Control (RRC) recovery request, the RRC recovery request carries second target device identification information, and the second target device identification information may be an I-RNTI of the second target device.
S703, matching the identifier information of the second target device in the identifier information base of the current base station.
Specifically, the database of the current base station includes an identification information base, and the identification information base is used for storing the I-RNTI of the user equipment generated by the current base station.
In practical application, the I-RNTI of the second target equipment is matched in the identification information base of the current base station to judge whether the I-RNTI of the second target equipment is generated by the current base station.
S705, when the second target device identification information is matched, recovering the context information of the second target device from the identification information base.
In practical application, when the identification information of the second target device is matched in the identification information base of the current base station, that is, when the I-RNTI of the second target device is generated by the current base station, the context information of the second target device is found from the identification information base, so as to recover the service connection of the second target device based on the context information.
S707, when the second target device identification information is not matched, determining a base station identification of a target base station, where the target base station is a base station that generates the second target device identification information.
