Description

Equipment access processing method and device and electronic equipment

Technical Field

The present application relates to the field of communications technologies, and in particular, to a device access processing method and apparatus capable of improving a success rate of device access to an SCG, and an electronic device.

Background

A fifth-generation mobile communication system (5th-generation, abbreviated as 5G) is a new-generation mobile communication technology, and there are two networking schemes, namely, a Non-independent Networking (NSA) and an independent networking (SA), which are obviously different from each other. NSA is deployed based on existing 4G infrastructure, and part of services and functions continue to depend on a Long Term Evolution (LTE) network (also known as a 4G network). The method has the advantages of saving construction cost and realizing quick coverage. The NSA transmits the 5G signals by transforming the 4G base station, the early laying speed is high, the cost is low, the 5G can be popularized as soon as possible, and users can enjoy the signals as many as possible. While the SA requires the construction of an independent base station, the time cost required for realizing large-scale coverage is high, but the SA has the characteristics of higher speed, lower delay and the like. In the future, during the development towards SA, NSA must have a long transition period.

Because the initial deployment stage of the New Radio (NR) of 5G is now in the transition process from 4G to 5G, the problem of abnormal configuration in the actual network cannot be avoided. When a User Equipment (User Equipment, UE) supporting an NSA mode adds an NR Secondary Cell Group (SCG) in some places, there may be an SCG addition failure. If SCG addition fails, the network issues a measurement B1 event; if the NR Reference Signal Received Power (RSRP) meets the threshold, the UE may add the same problematic NR cell. Wherein RSRP is one of the key parameters that can represent radio signal strength in LTE networks and the physical layer measurement requirement, and is the average of the received signal power over all REs (resource elements) that carry reference signals within a certain symbol.

In the same geographical location, if the UE frequently and repeatedly adds the same problematic NR cell, frequent measurements are made, and SCG addition always fails. This may decrease the success rate of UE accessing SCG, cause instability of UE data transmission, and increase additional power consumption.

In order to achieve the above object, the present application provides a device access processing method, including the following steps: acquiring failure information of which the state is SCG addition failure when user equipment accesses an NR cell to be accessed in an NSA mode, wherein the failure information comprises the geographical position of the user equipment, the cell ID of the NR cell to be accessed and the failure reason of SCG addition failure; comparing the acquired failure information with failure information recorded in a preset access blacklist, and judging whether the same failure information exists in the access blacklist or not; and if the same failure information exists in the access blacklist, controlling the user equipment to stop performing access attempt on the current NR cell to be accessed and continue performing access attempt on other NR cells.

In order to achieve the above object, the present application further provides an apparatus for device access processing, where the apparatus includes: a failure information obtaining unit, configured to obtain failure information in a state of SCG addition failure when a user equipment accesses an NR to be accessed cell in an NSA mode, where the failure information includes a geographic location where the user equipment is located, a cell ID of the NR to be accessed cell, and a failure reason of SCG addition failure; the comparison unit is used for comparing the acquired failure information with the failure information recorded in a preset access blacklist so as to judge whether the same failure information exists in the access blacklist or not; and the processing unit is used for controlling the user equipment to stop performing access attempt on the current NR cell to be accessed and continue performing access attempt on other NR cells when the comparison result obtained by the comparison unit indicates that the same failure information exists in the access blacklist.

Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are exemplary only for the purpose of illustrating the present application and are not to be construed as limiting the present application. In the description of the present application, the terms "first", "second" are used only to distinguish a plurality of elements from each other, and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1, a flowchart of a device access processing method according to a first embodiment of the present application is shown. The method comprises the following steps: s1, acquiring failure information of SCG addition failure when the user equipment accesses the NR cell to be accessed in the NSA mode; s2, comparing the acquired failure information with the failure information recorded in a preset access blacklist, and judging whether the same failure information exists in the access blacklist or not; and S3, if the same failure information exists in the access blacklist, controlling the user equipment to stop performing access attempt on the current NR cell to be accessed and continue performing access attempt on other NR cells. A detailed explanation is given below.

In step S1, failure information in a state of SCG addition failure is obtained when the user equipment accesses the NR cell to be accessed in the NSA mode. The failure information includes the geographical location of the user equipment, the cell ID of the NR cell to be accessed, and a failure reason for SCG addition failure.

Specifically, the corresponding geographical location may be obtained from Measurement information (Measurement Report) reported by the UE; the cell ID of the NR cell to be accessed may be acquired according to an RRC Reconfiguration state (RRC Connection Reconfiguration). The acquired failure information may be stored in a modem EFS file system of the UE.

In a further embodiment, the failure reason may be obtained according to the NR RRC reconfiguration state and according to a preset condition. Specifically, the correspondence between the failure reason and the failure value may be predefined in the RRC layer of the user equipment; and after the user equipment acquires the corresponding failure value according to the RRC reconfiguration state, acquiring the failure reason of SCG addition failure of the user equipment in the NSA mode according to the corresponding relation.

There are three layers of information for the control plane between the UE and the base station (e.g., evolved Node-B, eNB): the first Layer is a Physical Layer (PL), the second Layer is a Medium Access Control (MAC), and the third Layer is a Radio Resource Control (RRC); that is, the RRC processes the third layer information of the control plane between the UE and the eNB. The corresponding relation between the failure reason and the failure value can be predefined in the RRC layer of the UE according to a 3GPP protocol, and the RRC layer of the UE can automatically judge the RRC reconfiguration state; and the UE acquires the corresponding failure value according to the RRC reconfiguration state and further acquires the corresponding failure reason according to the corresponding relation. The RRC layer may also report the failure reason to a corresponding base station (e.g., a corresponding 4G base station); meanwhile, a file can be established in the modem EFS file system of the UE for storing information such as failure reasons and failure times.

The UE supporting the NSA mode may join the 5G network in an SCG adding manner, but because the 5G network is in a network deployment stage, it is inevitable that the UE network transmission is abnormal and the power consumption is increased because the network configuration is abnormal, not the UE configuration. After the UE receives the RRC connection reconfiguration, various types of failures may occur during the SCG addition process. Specifically, the failure reasons include: t310 timeout (T310-Expiry), user equipment synchronization Failure in SCG cell (Synch reconfiguration Failure-SCG), random Access Failure (random Access protocol), number of times of RLC retransmission (RLC-MaxUMRetx), SRB3 encryption Failure (SRB3-Integrity Failure), SCG reconfiguration Failure (SCG-reconfiguration Failure).

In step S2, the obtained failure information is compared with the failure information recorded in a preset access blacklist, and whether the same failure information exists in the access blacklist is determined.

Specifically, the access blacklist includes at least one failure information record, and each of the failure information records is recorded with a corresponding geographic location, a cell ID, and a failure reason. And when the geographic position, the cell ID and the failure reason in the acquired failure information are completely the same as the geographic position, the cell ID and the failure reason in any failure information record in the access blacklist, judging that the same failure information exists in the access blacklist. The access blacklist may be stored in a file established in the UE's modem EFS file system.

Regarding step S3: and if the same failure information exists in the access blacklist, controlling the user equipment to stop performing access attempt on the current NR cell to be accessed and continue performing access attempt on other NR cells. When it is determined that the same failure information does not exist in the access blacklist, the user equipment may be controlled to continue to perform an access attempt on the current NR cell to be accessed, and other operations may also be performed to further optimize the access operation.

For the ue access in the NSA mode, if it is determined that the failure information of the ue accessing a certain NR cell in a certain geographic location is the same as a certain piece of failure information recorded in a preset access blacklist, the access attempt is not performed on the current to-be-accessed NR cell, and instead, the access attempt is performed on other NR cells, so that the success rate of the device accessing the SCG can be improved.

In a further embodiment, the method further comprises the steps of: s4, when judging that the same failure information does not exist in the access blacklist, updating the failure times of the acquired failure information; s5, judging whether the failure times are larger than or equal to a preset time threshold, if so, executing a step S3, otherwise, executing a step S6; s6, controlling the user equipment to continue to perform access attempt to the current NR cell to be accessed.

That is, for UE access in NSA mode, it is determined whether frequent access to SCG fails when the UE accesses a certain NR cell in a certain geographical location; if the frequent access to the SCG fails, the access attempt is not performed on the current NR cell to be accessed, and the access attempt is performed on other NR cells, so that the success rate of the equipment to access the SCG can be improved.

In a further embodiment, the failure times are failure times of the same geographical location, the same cell ID, and the same failure reason. For example, the number of failures due to timeout of T310 in the same geographical location and the same cell ID is denoted as a11, the number of failures due to synchronization failure of the UE in the SCG cell is denoted as a12, the number of failures due to random access failure is denoted as a13, the number of failures due to failure exceeding the number of RLC retransmissions is denoted as a14, the number of failures due to encryption failure of SRB3 is denoted as a15, and the number of failures due to SCG reconfiguration failure is denoted as a 16. And when judging whether the failure times are larger than or equal to a preset time threshold value, judging the failure times of the same geographic position, the same cell ID and the same failure reason. For example, for the failure times a11 of the same geographical location, the same cell ID, and the failure cause of T310 timeout, the failure times a11 is compared with the failure times threshold a 01; the failure frequency threshold a01 is a failure frequency threshold whose failure cause is T310 timeout. For example, the failure times a13 of the random access failure in the same geographical location, the same cell ID and the failure reason are compared with a failure time threshold a 03; the failure frequency threshold a03 is a failure frequency threshold in which the reason for failure is a random access failure. By subdividing the failure reasons and comparing the corresponding times, the access operation can be optimized more reasonably.

The failure frequency threshold corresponding to each failure reason may be stored in a file established in the modem EFS file system of the UE. The geographical location, cell ID, failure cause, failure times, etc. obtained during the current access may also be stored in a file established in the modem EFS file system of the UE. And reading and comparing values in corresponding files, and judging corresponding failure times only if the same geographical position, the same cell ID and the same failure reason are met.

In a further embodiment, the method further comprises: and when the failure times are judged to be larger than or equal to a preset time threshold value, recording the failure information to the access blacklist. Therefore, when the user equipment performs the access attempt of the NR cell again in the NSA mode, the obtained failure information is compared with the failure information recorded in the preset access blacklist, and when the same failure information exists in the access blacklist, the user equipment can be directly controlled to stop performing the access attempt on the current NR cell to be accessed and continue performing the access attempt on other NR cells, so that repeated access attempt operations are avoided.

In a further embodiment, the method further comprises: starting timing when the failure information with the SCG adding failure state is acquired; when the failure times are judged to be smaller than a preset time threshold value, further judging whether the timing time is larger than or equal to the preset timing threshold value; if the timing time is greater than or equal to a preset timing threshold (for example, 5 to 10 minutes), clearing the failure times, and waiting for the next access attempt; and if the timing time is less than a preset timing threshold value, controlling the user equipment to continue to perform access attempt on the current NR cell to be accessed. That is, for the user equipment access in the NSA mode, it is determined whether the UE fails to access the SCG frequently within a certain time period when the UE accesses a certain NR cell at a certain geographical location; if the frequent access of the SCG fails within a certain time period, the access attempt is not performed on the current NR cell to be accessed, and the access attempt is performed on other NR cells, so that the success rate of the SCG accessed by the equipment can be improved. And if the SCG is not frequently accessed within a certain time period, the access attempt is not forbidden to be continuously carried out on the current NR cell to be accessed. For example, after failing to attempt access to the same cell ID on the first day, at the same geographical location, access attempts to the same cell ID on the second day, at the same geographical location, are not restricted. Therefore, the device access is reasonably configured, and the power consumption of the access attempt and the access attempt of the accessible NR cell are balanced.

In the device access processing method provided in this embodiment, when a user equipment supporting an NSA mode joins a 5G network in an SCG addition manner, if it is determined that failure information of the user equipment accessing a certain NR cell in a certain geographic location is the same as a certain piece of failure information recorded in a preset access blacklist, an access attempt is not performed on the current to-be-accessed NR cell, and instead, an access attempt is performed on other NR cells. For the area with the SCG network configuration abnormity, the success rate of the user equipment accessing the SCG can be improved, the user data transmission stability is improved, and the network transmission abnormity and the power consumption increase of the user equipment caused by the network configuration abnormity are avoided.

Referring to fig. 2, a flowchart of a device access processing method according to a second embodiment of the present application is shown. In this embodiment, the device access processing method includes the following steps: s21, acquiring failure information of SCG addition failure of the user equipment in the NSA mode, and starting timing; s22, judging whether the access blacklist has failure information which is the same as the acquired failure information, if so, executing a step S23, otherwise, executing a step S24; s23, controlling the user equipment to stop performing access attempt on the current NR cell to be accessed and continue performing access attempt on other NR cells; s24, updating the failure times corresponding to the failure information; s25, judging whether the failure times corresponding to the failure information are larger than or equal to a preset time threshold, if so, executing a step S26, otherwise, executing a step S27; s26, recording the failure information to the access blacklist and executing the step S23; s27, judging whether the timing time is larger than or equal to a preset timing threshold, if so, executing a step S28, otherwise, executing a step S29; s28, clearing the failure times and waiting for the next access attempt; and S29, controlling the user equipment to continue to perform access attempt on the current NR cell to be accessed, and returning to the step S21 (wherein the timing is continued, and the timing is not re-timed at this time).

In the device access processing method provided in this embodiment, when a UE supporting an NSA mode joins a 5G network in an SCG adding manner, it is determined whether the UE fails to frequently access an SCG within a preset time when the UE accesses a certain NR cell in a certain geographical location; and if the frequent access to the SCG fails, the access attempt is not performed on the current NR cell to be accessed, and the access attempt is performed on other NR cells. For the area with the SCG network configuration abnormity, the success rate of the UE accessing the SCG can be improved, the data transmission stability of the user can be improved, and the network transmission abnormity of the UE and the power consumption increase caused by the network configuration abnormity can be avoided.

Based on the same inventive concept, the application also provides a device access processing device.

Referring to fig. 3, an architecture diagram of a device access processing apparatus according to a third embodiment of the present application is provided. The device access processing device of the embodiment comprises: a failure information acquisition unit 31, a comparison unit 32, and a processing unit 33.

Specifically, the failure information obtaining unit 31 is configured to obtain failure information in a state of SCG addition failure when the user equipment accesses the to-be-accessed NR cell in the NSA mode. The failure information includes the geographical location of the user equipment, the cell ID of the NR cell to be accessed, and a failure reason for SCG addition failure. The failure information obtaining unit 31 may obtain a corresponding geographical location from Measurement information (Measurement Report) reported by the UE; the cell ID of the NR cell to be accessed may be acquired according to an RRC Reconfiguration state (RRC Connection Reconfiguration); the failure reason can be obtained according to the NR RRC reconfiguration state and the preset condition. The acquired failure information may be stored in a modem EFS file system of the UE.

Specifically, the correspondence between the failure reason and the failure value may be predefined in the RRC layer of the user equipment; and after the user equipment acquires the corresponding failure value according to the RRC reconfiguration state, acquiring the failure reason of SCG addition failure of the user equipment in the NSA mode according to the corresponding relation.

Specifically, the failure reasons include: t310 timeout (T310-Expiry), user equipment synchronization Failure in SCG cell (Synch reconfiguration Failure-SCG), random Access Failure (random Access protocol), number of times of RLC retransmission (RLC-MaxUMRetx), SRB3 encryption Failure (SRB3-Integrity Failure), SCG reconfiguration Failure (SCG-reconfiguration Failure).

The comparing unit 32 is configured to compare the acquired failure information with failure information recorded in a preset access blacklist, so as to determine whether the same failure information exists in the access blacklist. Specifically, the access blacklist includes at least one failure information record, and each of the failure information records is recorded with a corresponding geographic location, a cell ID, and a failure reason. And when the geographic position, the cell ID and the failure reason in the acquired failure information are completely the same as the geographic position, the cell ID and the failure reason in any failure information record in the access blacklist, judging that the same failure information exists in the access blacklist. The access blacklist may be stored in a file established in the UE's modem EFS file system.

The processing unit 33 is configured to control the user equipment to stop performing the access attempt on the current to-be-accessed NR cell and continue performing the access attempt on other NR cells when the comparison result obtained by the comparing unit 32 indicates that the same failure information exists in the access blacklist. When it is determined that the same failure information does not exist in the access blacklist, the user equipment may be controlled to continue to perform an access attempt on the current NR cell to be accessed, and other operations may also be performed to further optimize the access operation.

In a further embodiment, the processing unit 33 is further configured to update the failure times of the acquired failure information when the comparison result obtained by the comparing unit 32 is that the same failure information does not exist in the access blacklist. The comparing unit 32 is further configured to determine whether the failure times are greater than or equal to a preset time threshold; the processing unit 33 is further configured to control the ue to stop performing the access attempt on the current to-be-accessed NR cell and continue performing the access attempt on other NR cells when the comparison result obtained by the comparing unit 32 is that the failure number is greater than or equal to a preset number threshold; and if the comparison result obtained by the comparing unit 32 is that the failure times are smaller than a preset time threshold, controlling the user equipment to continue to perform access attempt on the current to-be-accessed NR cell.

In a further embodiment, the failure times are failure times of the same geographical location, the same cell ID, and the same failure reason. The failure frequency threshold corresponding to each failure reason may be stored in a file established in the modem EFS file system of the UE. The geographical location, cell ID, failure cause, failure times, etc. obtained during the current access may also be stored in a file established in the modem EFS file system of the UE. And improving and reading values in corresponding files for comparison, and judging corresponding failure times only if the same geographic position, the same cell ID and the same failure reason are met.

In a further embodiment, the processing unit 33 is further configured to record the failure information to the access blacklist when the comparison result obtained by the comparing unit 32 is that the failure time is greater than or equal to a preset time threshold. Therefore, when the user equipment performs the access attempt of the NR cell again in the NSA mode, the obtained failure information is compared with the failure information recorded in the preset access blacklist, and when the same failure information exists in the access blacklist, the user equipment can be directly controlled to stop performing the access attempt on the current NR cell to be accessed and continue performing the access attempt on other NR cells, so that repeated access attempt operations are avoided.

In a further embodiment, the apparatus may further comprise a timing unit 34. The timing unit 34 starts timing when the failure information acquisition unit 31 acquires the failure information whose status is SCG addition failure. When the comparison result obtained by the comparing unit 32 is that the failure times are smaller than the preset time threshold, the timing time is further compared with a preset timing threshold (for example, 5 to 10 minutes) to determine whether the timing time is greater than or equal to the preset timing threshold; the processing unit 33 is further configured to clear the failure times and wait for a next access attempt when the comparison result obtained by the comparing unit 32 is that the timing time is greater than or equal to a preset timing threshold; and when the comparison result obtained by the comparing unit 32 is that the timing time is less than the preset timing threshold, controlling the user equipment to continue to perform access attempt on the current to-be-accessed NR cell. That is, for the user equipment access in the NSA mode, it is determined whether the UE fails to access the SCG frequently within a certain time period when the UE accesses a certain NR cell at a certain geographical location; if the frequent access of the SCG fails within a certain time period, the access attempt is not performed on the current NR cell to be accessed, and the access attempt is performed on other NR cells, so that the success rate of the SCG accessed by the equipment can be improved. And if the SCG is not frequently accessed within a certain time period, the access attempt is not forbidden to be continuously carried out on the current NR cell to be accessed. For example, after failing to attempt access to the same cell ID on the first day, at the same geographical location, access attempts to the same cell ID on the second day, at the same geographical location, are not restricted. Therefore, the equipment access is reasonably configured, and the power consumption of the access attempt and the access attempt of the accessible cell are balanced.

The method of claim 1, wherein a correspondence of failure reasons to failure values is predefined at a user equipment RRC layer; and after the user equipment acquires the corresponding failure value according to the RRC reconfiguration state, acquiring the failure reason of SCG addition failure of the user equipment in the NSA mode according to the corresponding relation.

3. The method of claim 1, wherein the failure reason comprises: t310 time-out, synchronization failure of user equipment in SCG cell, random access failure, number of RLC retransmissions exceeded, SRB3 ciphering failure, SCG reconfiguration failure.

4. The method of claim 1, wherein the access blacklist includes at least one failure information record, and each failure information record has a corresponding geographical location, a cell ID, and a failure reason recorded therein; and when the geographic position, the cell ID and the failure reason in the acquired failure information are completely the same as the geographic position, the cell ID and the failure reason in any failure information record in the access blacklist, judging that the same failure information exists in the access blacklist.

5. The method of claim 1, wherein the method further comprises:

updating the failure times of the acquired failure information when the same failure information does not exist in the access blacklist;

judging whether the failure times are larger than or equal to a preset time threshold value or not;

if the failure times are larger than or equal to a preset time threshold value, controlling the user equipment to stop performing access attempt on the current NR cell to be accessed and continue performing access attempt on other NR cells;

and if the failure times are smaller than a preset time threshold value, controlling the user equipment to continue to perform access attempt on the current NR cell to be accessed.

6. The method of claim 5, wherein the number of failures is the number of failures for the same geographical location, the same cell ID, and the same reason for failure.

7. The method of claim 5, wherein the method further comprises: and when the failure times are judged to be larger than or equal to a preset time threshold value, recording the failure information to the access blacklist.

8. The method of claim 5, wherein the method further comprises:

starting timing when the failure information with the SCG adding failure state is acquired;

when the failure times are judged to be smaller than a preset time threshold value, further judging whether the timing time is larger than or equal to the preset timing threshold value;

and if the timing time is greater than or equal to a preset timing threshold value, clearing the failure times.

9. An apparatus access processing device, the apparatus comprising:

a failure information obtaining unit, configured to obtain failure information in a state of SCG addition failure when a user equipment accesses an NR to be accessed cell in an NSA mode, where the failure information includes a geographic location where the user equipment is located, a cell ID of the NR to be accessed cell, and a failure reason of SCG addition failure;

the comparison unit is used for comparing the acquired failure information with the failure information recorded in a preset access blacklist so as to judge whether the same failure information exists in the access blacklist or not;

and the processing unit is used for controlling the user equipment to stop performing access attempt on the current NR cell to be accessed and continue performing access attempt on other NR cells when the comparison result obtained by the comparison unit indicates that the same failure information exists in the access blacklist.

10. An electronic device, characterized in that the electronic device comprises:

a processor; and

a memory storing computer-executable instructions that, when executed by the processor, cause the steps of the method of any one of claims 1 to 8 to be performed.
