Description
[ technical field ] A method for producing a semiconductor device
The present disclosure relates to the field of communications, and in particular, to a communication processing method, an apparatus, and a base station.
[ background of the invention ]
Currently, various parameters related to ue (user equipment) access in a common LTE (Long Term Evolution) base station are configured by comprehensively considering various optimization targets of the existing network. For example, random access preambles are assigned based on estimating contention based random access and non-contention based random access demands based on an existing network traffic model. The scheduling of the uplink resource needs to be performed according to the SR (Service Request) and BSR (Buffer Status Report) reported by the UE and the priority of the UE. A BI (Backoff Indicator) mechanism of the random access procedure is sent opportunistically according to the eNodeb load status. And, the signaling flow of UE access and release is implemented strictly according to the 3gpp (3rd Generation Partnership Project) protocol.
However, the parameter configuration, resource scheduling manner, signaling flow implementation, and the like of the conventional LTE small cell are mainly to solve the access problem of the current network common wireless UE, and it is required to ensure that a certain quality of service is provided for the accessed UE. Therefore, the conventional LTE small base station is relatively limited in UE access amount, and cannot meet the requirement that a user in a specific industry wants to quickly acquire a large amount of UE user identities (i.e., UE IDs) without providing service to the UE.

Example one
The application scenarios of the embodiment of the invention are as follows: users in a specific industry want to quickly acquire user identifiers of massive UEs through a base station in a dense traffic area such as a subway, a station, and the like. The application scene aims at optimizing the UE access amount, and the capability and the quality of the base station for providing services for the UE do not need to be considered. In this context, the inventor proposes a communication processing method flow aiming at optimizing UE access amount.
It should be noted that the communication processing method of the embodiment of the present invention is mainly used in a special industry that has acquired user qualifications. Because the base station needs to access the core network of the operator to acquire the user identification information of the user, the special industry has the authority to acquire the user identity, and the operator can only allow the base station of the embodiment of the invention to access the core network under the requirement of the qualified department. That is, the base station of the embodiment of the present invention can only function if it is supported by the operator. The base station of the embodiment of the invention can realize the aim of obtaining the user information without obtaining the user information by any person or unit. Therefore, the base station in the embodiment of the invention does not operate independently, needs to be authorized, can be supervised, does not take actions which damage public interests, and can ensure that the base station acquires the user identification information as legal actions.
The embodiment of the invention provides a communication processing method, which is applied to a base station.
Fig. 1 is a flowchart illustrating a communication processing method according to an embodiment of the present invention. As shown in fig. 1, in this embodiment, the communication processing method may include the following steps:
s101, establishing wireless connection with terminal equipment;
s102, acquiring identification information of the terminal equipment with the established wireless connection;
s103, sending a connection rejection indication message to the terminal equipment which has acquired the identification information;
and S104, responding to the condition that the triggering condition is met, and releasing the resources related to the terminal equipment.
After acquiring the identification information of the terminal device, S103 sends a connection rejection indication message to the terminal device that has acquired the identification information, so as to avoid that the terminal device that has acquired the identification information (that means the base station has already acquired the identification information of the terminal device) repeatedly accesses the base station and occupies resources of the base station, so that other UEs that have not been acquired by the base station with the identification information can more easily and faster access the base station.
The terminal device in S104 refers to the UE that has already acquired the identification information by the base station. The purpose of the base station communicating with the UE by using the communication processing method flow of this embodiment is to acquire the user identifier of the UE as much as possible, rather than to provide specific services to the UE. Therefore, in S104, when the trigger condition is satisfied, the base station releases the resources related to the terminal device, so as to quickly vacate the resources, and enable other UEs that have not been acquired by the base station with the identification information to more easily and quickly access the base station. Therefore, the base station can quickly acquire the user identifications of a large number of UE.
For example. It is assumed that one base station can access 10 UEs simultaneously, and the interaction time of each UE with the base station is the same (this is assumed here for convenience of explanation and is not necessary in practical application). The current base station has access to 10 UEs simultaneously, namely UE 1-UE 10, and after acquiring identification information ID 1-ID 10 of UE 1-UE 10, the base station respectively sends connection rejection indication messages to UE 1-UE 10, and then immediately releases resources related to UE 1-UE 10 when a trigger condition is met, so that the released resources can be used by other 10 un-accessed UEs. After releasing the resources related to the UEs 1 to 10, the base station connects to the UEs 11 to 20 by using the released resources to obtain the identification information IDs 11 to 20 of the UEs. Assuming that 5 seconds are required for each UE to interact with the base station, the base station can acquire the identification information of 20 UEs within 10 seconds. If the base station does not send a connection rejection indication message to the IDs 1 to 10 after acquiring the identification information IDs 1 to 10 of the UEs 1 to 10, some UEs of the UEs 1 to 10 may repeatedly access the base station within the next 5 seconds after the base station releases resources related to the UEs 1 to 10, for example, the UEs 1 and the UEs 2 repeatedly access the base station, and the number of the identification information of the UEs acquired by the base station is 18 within 10 seconds. However, if the base station only releases the resources related to the UEs 1 to 7 and does not release the resources related to the UEs 8 to 10 after acquiring the identification information IDs 1 to 10 of the UEs 1 to 10, the base station can only access 7 UEs which are not duplicated with the UEs 1 to 10 in the next 5 seconds, and thus the number of the identification information of the UEs acquired by the base station is 17 in 10 seconds.
It can be seen that, through S103 and S104, the accessed UE cannot access the base station any more, and after the base station acquires the UE user identifier, the resource related to the UE is immediately released when the trigger condition is satisfied, and the released resource can be used by other UEs that are not accessed to access the base station, so that the success probability and the access number of the terminal device that is not acquired by the base station with the identifier information to access the base station are increased, thereby increasing the speed of accessing the base station by the UE, further increasing the speed of acquiring the UE user identifier by the base station, and enabling the base station to acquire a large number of UE user identifiers quickly.
In a specific implementation procedure, before establishing a wireless connection with a terminal device, the communication processing method may further include: and configuring the values of the specified configuration parameters in the base station according to the specified principle.
The specified principle may be a principle of maximizing the access amount of the terminal device.
For example, if the value of the specified configuration parameter in the base station is not set according to the principle of optimizing the access amount of the terminal device, the base station can simultaneously access 10 UEs, and after the value of the specified configuration parameter in the base station is set according to the principle of optimizing the access amount of the terminal device, the number of UEs that the base station can simultaneously access will be greater than 10, for example, may be 20, so that the speed of acquiring the UE identifier by the base station can be increased.
For example, it is still assumed that the interaction time of each UE with the base station is the same, 5 seconds. If the values of the specified configuration parameters are set in a conventional manner, the base station can access 10 UEs simultaneously, and the base station can acquire the user identities of 20 UEs within 10 seconds. After the values of the designated configuration parameters in the base station are set according to the principle of optimizing the access amount of the terminal equipment, the base station can be simultaneously accessed to 20 pieces of UE, so that the base station can acquire the user identifications of 40 pieces of UE within 10 seconds, and therefore, after the values of the designated configuration parameters in the base station are set according to the principle of optimizing the access amount of the terminal equipment, the speed of acquiring the user identifications of the UE by the base station is greatly increased.
In a specific implementation process, configuring the values of the specified configuration parameters in the base station according to the specified principle may include: configuring the value of the access level Q-RxLevMin to be a numerical value smaller than the lower limit value of the conventional range of the access level Q-RxLevMin; configuring the number of contention-based random access codes, numberOfRA-Preambles, to be a value greater than the number of non-contention-based random access codes; configuring the number sizeoffra-preamblinggroup pa of the group a preambles to a value greater than the number of the group B preambles; the Prach spectral offset value Prach-FreqOffset is configured to be a value greater than a specified upper limit value.
In a specific implementation, the value of the access level Q-RxLevMin is-70, the number of contention-based random access codes numberOfRA-Preambles is 64, the number of group a Preambles sizeoffra-preamblesGroupA is 40, and the Prach spectral offset value Prach-FreqOffset is 92.
The purpose of configuring the value of the access level Q-RxLevMin to a value smaller than the lower limit value of the conventional range of Q-RxLevMin is to make the cell of the base station easier for the UE to select access during the cell selection phase. For example, the access level (Q-RxLevMin) of a conventional LTE small base station is generally between-124 dBm and-128 dBm, and when the value of Q-RxLevMin is set to a limit value of-70, i.e., -140dBm, the cell of the base station is most easily selected for access by the UE during a cell selection phase.
When the number of contention-based random access codes, numberOfRA-Preambles, is configured to be greater than the number of non-contention-based random access codes, the number of contention-based random access codes (numberOfRA-Preambles) may be configured to be the limit value 64, that is, the non-contention-based random access codes are not reserved. In an application scenario of acquiring the user identifier of the UE, the base station may rapidly release the UE after acquiring the ID of the UE, so that the LTE small station may not provide service for the UE, may not connect to the core network of the current network, and may not have the non-competitive access requirements such as handover. Therefore, all random access codes are provided for random access based on competition so as to be used for accessing massive UE, and the speed of acquiring the user identification of the UE by the base station can be further increased.
It should be noted that the base station does not connect to the core network of the current network after acquiring the ID of the UE. Therefore, the acquired ID of the UE cannot be transmitted to other places through the core network, and the safety of user information is guaranteed.
In the case where the number of contention-based random access codes (numberOfRA-Preambles) is configured as the limit value 64, it is considered that the number sizeoffra-preambsgroupa of the a-group Preambles may be set to 40.
In a specific implementation process, establishing a wireless connection with a terminal device may include: responding to a received Radio Resource Control (RRC) connection request sent by the terminal equipment, sending an RRC connection establishment message to the terminal equipment so that the terminal equipment can send a scheduling request to the base station according to the RRC connection establishment message; and in response to receiving the scheduling request sent by the terminal equipment, scheduling the corresponding resource for the terminal equipment so that the terminal equipment can be connected to the base station by using the scheduled resource.
In the LTE system, after receiving Msg4, the UE reports SR to transmit Msg5(RRC Connection Setup complex) and requests uplink resources. And the eNB (namely the base station) side indicates the UE after finishing the uplink resource scheduling. The UE then sends Msg5 up to the eNB along with the Attach Request NAS message. Generally, after receiving an SR, an LTE base station issues an UL grant (uplink scheduling grant), first configures a small portion of resources for a UE (enough UE to upload a BSR), and then the UE informs an eNB of the data amount to be transmitted by the UE through the BSR.
And responding to the received scheduling request sent by the terminal equipment, scheduling corresponding resources for the terminal equipment, namely after the base station receives the SR, scheduling the resources for the Msg5 by the base station, so that the delay time can be reduced, the UE can be connected to the base station more quickly, and the base station can acquire the identification information of the UE more quickly.
In a specific implementation process, in response to receiving a scheduling request sent by a terminal device, scheduling a corresponding resource for the terminal device may include: and in response to receiving the scheduling request sent by the terminal equipment, scheduling at least six PRBs (Physical Resource blocks) for the terminal equipment.
And in response to the received scheduling request sent by the terminal equipment, scheduling at least six Physical Resource Blocks (PRBs) for the terminal equipment, and ensuring that the base station cannot be segmented when the Msg5 reports to the base station, so that the UE can access the base station more quickly, and the success rate of UE access can be improved.
In a specific implementation procedure, the communication processing method may further include: when receiving an Access request of a terminal device, if the Access volume of the current terminal device reaches a specified value, sending an RAR MAC PDU (Random Access Media Access Control Protocol Data Unit, Random Access Response Media Access Control layer Protocol Data Unit) to the terminal device; when the RAR MAC PDU to be currently transmitted is the last RAR MAC PDU in an RAR-window (Random Access Response window), a backoff indicator BI is added to the RAR MAC PDU to be currently transmitted.
That is to say, the base station does not determine whether to send the BI according to the load condition, but adopts a strategy of issuing the BI in time, so that a large amount of accessed UEs can be scattered in time, and the probability of preamble collision caused by accumulation of a large amount of repeated random accesses along with the time is prevented from increasing.
For example, the base station may estimate the number of RAR MAC PDUs that can be sent in the RAR-window first, and bring the BI when determining that the current RAR MAC PDU is the last RAR-window. For example, when the frame configuration is 2 and the PRACH configuration Index is 1, at most 4 DL (downlink) subframes in the RAR-window can transmit MSG 2. The BI may be carried on the 4 th RAR at this time, with the value of the BI determined based on the number of UEs remaining unprocessed random access.
In a specific implementation process, the trigger condition may be: receiving a response message of the terminal equipment responding to the connection rejection indication message within a specified time after the connection rejection indication message is sent to the terminal equipment; or the time length from the moment of sending the connection rejection indication message to the terminal equipment reaches the specified time length.
Wherein, the Connection rejection indication message is an attribute request or a TAU request, if the RRC Connection setup complete message carries the attribute request, the base station sends the attribute request to the UE, and if the RRC Connection setup complete message carries the TAU request, the base station sends the TAU request to the UE.
The base station starts a timer while issuing an attach reject or a TAU reject. And if the base station receives an acknowledgement message ACK returned by the UE before the timer is overtime, releasing the related resources of the UE. If the UE does not receive the attachreject or the TAU reject or the UE receives the attachreject or the TAU reject but the base station does not receive the ACK (acknowledgement) message returned by the UE due to reasons such as channel environment, and the like, after the timer is timed out, the base station immediately releases the local UE resource in order to achieve the purpose of quickly releasing the UE resource.
In a specific implementation process, the base station is a long term evolution LTE base station.
