Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a terminal network access control method, related devices, and a wireless communication system. Background Art

[0002] In the field of wireless communications, when a terminal accesses a base station, it needs to establish a signaling radio bearer (SRB) and a data radio bearer (DRB). When establishing a DRB, the core network allocates core network and base station resources to the user terminal based on the user terminal's priority.

[0003] However, when establishing an SRB, the terminal simply sends an RRC setup request message to the base station, and the base station responds to the RRC setup request message to establish a signaling radio bearer for the terminal. In this process, there is usually no priority processing mechanism. The base station does not distinguish the priorities of different terminals, and cannot implement preferential treatment for specific terminals. Summary of the Invention

On this basis, when the first type of terminal sends an RRC establishment request message to the base station, the first reserved value is recorded in the first reserved data bit of the establishment reason field, wherein the first reserved data bit is the reserved data bit allocated for the first type of terminal in the establishment reason field, and the first reserved value is the reserved value allocated for the first type of terminal.

[0055] The technical solution of the embodiment of the present application is applicable to the application scenario of establishing a signaling radio bearer SRB between the terminal and the base station. The technical solution of the embodiment of the present application can enable the base station to clarify the priority of the terminal when establishing an SRB with the terminal, and establish an SRB with the terminal according to the terminal priority, so that the high-priority terminal can have priority in establishing the SRB.

[0056] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0057] Exemplary Implementation Environment

[0058] Figure 1A schematic diagram of an exemplary application scenario of the technical solution proposed in an embodiment of the present application is shown. The scenario is a wireless communication system, which includes at least one terminal 1 and a base station 2. The terminal 1 and the base station 2 are connected through a wireless network. The wireless network can be any type of network, such as a wireless public communication network, a wireless private communication network, a wireless public private communication network, etc. The above-mentioned terminal 1 can be any type of communication terminal, such as a mobile phone, a mobile computer, a tablet computer, a wearable device, an industrial network device, a gateway device, or any other terminal device with a wireless communication function. The above-mentioned base station 2 can be any type of communication base station. For example, according to the communication mode, the above-mentioned base station 2 can be a 5G base station, a 4G base station, etc., and according to the station size and power size, the above-mentioned base station 2 can be a macro base station, a micro base station, a pico base station, a flying base station, etc.

[0059] In an embodiment of the present application, various terminal devices in industrial scenarios are used as terminal 1 in the above-mentioned wireless communication system, and a 5G base station GNB (the next Generation Node B) is used as base station 2 in the above-mentioned wireless communication system. The technical solution of the embodiment of the present application is exemplarily introduced based on the wireless communication system.

[0060] exist Figure 1 In the wireless communication system shown, when terminal 1 accesses the communication network of base station 2, it needs to establish SRB (Signaling Radio Bearer) and DRB (Data Radio Bearer) messages. When establishing the DRB, the core network allocates core network and base station resources to the user based on the relevant QoS settings. The relevant QoS settings allow high-priority users to preempt the resources of lower-priority users, thereby ensuring the service of high-priority users.

[0061] However, SRB only implements relatively simple user access priority screening in very few scenarios, such as: GNB handles access attempts of "emergency", "mps-PriorityAccess" and "mcs-PriorityAccess" (i.e. emergency calls, multimedia, data users) with high priority establishment. This priority screening is effective only under conditions where the RRC rejects these access attempts in extreme network loads, which may threaten the stability of GNB.

[0062] That is to say, during the normal SRB establishment process, the terminal simply sends an RRC establishment request message to the base station, and the base station responds to the RRC establishment request message to establish an RRC connection with the terminal, that is, to establish a signaling radio bearer for the terminal. In this process, there is usually no priority processing mechanism. The base station does not distinguish the priorities of different terminals and cannot implement priority processing for specific terminals. Therefore, according to the current terminal access solution, the base station cannot use SRB messages to distinguish the priority of user access and the resource weight to be obtained. This results in the inability of terminals with urgent services to quickly access the network and obtain sufficient network resources. It may also lead to unreasonable allocation of network resources and reduce the efficiency of network resource utilization.

[0063] Exemplary Methods

[0064] Figure 2 A flow chart of a terminal network access control method proposed in an embodiment of the present application is shown. The terminal network access control method is applied to Figure 1 The wireless communication system shown is specifically implemented by cooperation between a terminal 1 and a base station 2 in the wireless communication system.

[0065] As the basis for executing the terminal access control method proposed in the embodiment of the present application, the base station 2 stores the reserved data bits allocated in advance for each terminal type in the establishment reason field of the RRC establishment request message in the preset terminal type, the reserved value allocated for each terminal type, and the access priority information corresponding to each reserved value.

[0066] Specifically, in the 3GPP protocol, certain data bits in the EstablishmentCause field in the RRCSetUpRequest message are reserved. Specifically, the spare1, spare2, spare3, spare4, spare5, and spare6 bits in the EstablishmentCause field are reserved, meaning that these bits are idle. Under normal circumstances, when a terminal sends an RRCSetUpRequest message to a base station, the spare1, spare2, spare3, spare4, spare5, and spare6 bits in the EstablishmentCause field are all empty, meaning they carry no information.

[0067] This embodiment of the present application allocates the aforementioned reserved data bits to different types of terminals. Specifically, within each reserved data bit, different terminal types are allocated reserved data bits. For example, spare1 is allocated to industrial pads, spare2 is allocated to alarm terminals, spare3 is allocated to inspection equipment, spare4 is allocated to gateway devices, and so on. With this allocation, different types of terminals can carry data content within their allocated reserved data bits.

[0068] Based on the above-mentioned reserved data bit allocation, the embodiment of the present application further allocates a reserved value to each type of terminal, and sets a corresponding access priority for each reserved value.

[0069] The above-mentioned reserved value can be a numerical value or an identifier consisting of text and / or characters. For example, the reserved value "00000001" can be set for the terminal type assigned the reserved data bit "spare1", the reserved value "00000010" can be set for the terminal type assigned the reserved data bit "spare2", the reserved value "00000011" can be set for the terminal type assigned the reserved data bit "spare3", the reserved value "00000100" can be set for the terminal type assigned the reserved data bit "spare4", the reserved value "00000101" can be set for the terminal type assigned the reserved data bit "spare5", and the reserved value "00000110" can be set for the terminal type assigned the reserved data bit "spare6".

[0070] According to the above introduction, different reserved values ​​are allocated to different terminal types, and different access priorities are set for different reserved values. In addition, the reserved data bits allocated to each terminal type, the reserved values ​​allocated to each terminal type, and the access priority information corresponding to each reserved value are all stored in the base station.

[0071] Based on the above configuration, an embodiment of the present application proposes a terminal network access control method. This method enables a certain type of terminal to carry a reserved value pre-assigned for that type of terminal in the reserved data bit in the EstablishmentCause field of the RRC establishment request message when establishing an SRB. When the base station receives the RRC establishment request message, it determines the terminal network access priority based on the reserved value in the reserved data bit, and then establishes an SRB with the terminal based on the terminal network access priority.

[0072] The following describes in more detail the terminal access control method proposed in the embodiment of the present application, using the processing process when a first-type terminal establishes an SRB with a base station. The above-mentioned first-type terminal is any one of the preset terminal types for which reserved data bits are pre-allocated in the establishment cause field of the RRC establishment request message.

[0073] See also Figure 2 As shown, the terminal network access control method proposed in the embodiment of the present application specifically includes:

[0074] S101. A first type terminal sends an RRC establishment request message including an establishment cause field to a base station, where a first reserved data bit of the establishment cause field records a first reserved value.

[0075] The first reserved data bit is a reserved data bit allocated to the first type terminal in the establishment reason field, and the first reserved value is a reserved value allocated to the first type terminal.

[0076] Specifically, assuming that the first type of terminal is an industrial pad, and according to the above embodiment, the reserved data bit "spare1" in the EstablishmentCause (the first reserved data bit) has been allocated to the industrial pad in advance, and the reserved value "00000001" (the first reserved value) has been allocated to the industrial pad. Then, when the first type of terminal sends an RRC setup request message RRCSetUpRequest containing the EstablishmentCause to the base station, the first type of terminal can carry the reserved value "00000001" in the spare1 reserved data bit in the EstablishmentCause of the RRCSetUpRequest message.

[0077] The above-mentioned RRC establishment request message may be an RRC establishment request message sent by the terminal when initiating RRC access, or may be an RRC re-establishment request message sent by the terminal in the RRC re-establishment process.

[0078] That is, when the first type terminal initiates an RRC access request to the base station, the terminal may send the above-mentioned RRC establishment request message including the establishment cause field to the base station, or when the first type terminal initiates an RRC re-establishment request to the base station, the terminal may also send the above-mentioned RRC establishment request message including the establishment cause field to the base station. As a result, whether the terminal initiates an RRC access request to the base station for the first time or when the terminal and the base station re-establish RRC, the terminal may add the reserved value allocated to the terminal to the reserved data bit allocated to the terminal when sending the RRC establishment request message to the terminal.

[0079] S102. The base station receives an RRC establishment request message including an establishment cause field sent by a first type terminal.

[0080] As described in step S101 above, when the first type terminal sends the RRC establishment request message RRCSetUpRequest to the base station, the first reserved value allocated for the first type terminal is added to the first reserved data bit of the establishment cause field EstablishmentCause.

[0081] Then, the base station may receive the RRC establishment request message including the establishment cause field sent by the first type terminal.

[0082] S103. The base station determines the network access priority of the first type of terminal according to the first reserved data bit, the first reserved value, and pre-stored access priority information corresponding to each reserved value.

[0083] Specifically, the base station pre-stores the terminal type corresponding to each reserved data bit, the reserved value allocated to each terminal type, and the access priority information corresponding to each reserved value.

[0084] On this basis, when the base station receives the RRCSetUpRequest message sent by the first type of terminal, it queries which reserved data bit carries the reserved value from each reserved data bit of the EstablishmentCause field of the message, and reads the reserved value from the reserved data bit carrying the reserved value.

[0085] Then, the base station can determine the network access priority of the first type of terminal that currently sends the RRC establishment request message by querying the pre-stored access priority information corresponding to each reserved value. Specifically, the base station retrieves a reserved value that is the same as the reserved value in the received RRC establishment request message from the pre-stored access priority information corresponding to each reserved value, and determines the network access priority of the first type of terminal based on the access priority information corresponding to the reserved value.

[0086] For the first type of terminal described above, assuming that the first type of terminal is an industrial pad, and according to the above embodiment, the reserved data bit "spare1" in the EstablishmentCause (the first reserved data bit) has been allocated to the industrial pad in advance, and the reserved value "00000001" (the first reserved value) has been allocated to the industrial pad. Then, when the first type of terminal sends an RRC establishment request message RRCSetUpRequest containing the EstablishmentCause to the base station, the first type of terminal can carry the reserved value "00000001" in the spare1 reserved data bit in the EstablishmentCause of the RRCSetUpRequest message.

[0087] When the base station receives the RRCSetUpRequest message from the industrial pad, it reads the reserved value "00000001" from the spare1 field in the EstablishmentCause field of the message. The base station then retrieves the access priority information corresponding to "00000001" from the pre-stored access priority information corresponding to each reserved value. The access priority corresponding to this access priority information is the network access priority of the industrial pad.

[0088] S104. The base station responds to the RRC establishment request of the first type of terminal according to the network access priority of the first type of terminal.

[0089] Specifically, after determining the network access priority of the first type of terminal, the base station responds to the RRC establishment request of the first type of terminal according to the network access priority of the first type of terminal, that is, decides whether to respond to the RRC establishment request of the first type of terminal immediately or to give priority to responding to the RRC establishment requests of other terminals.

[0090] Since there will be a large number of terminals within the coverage area of ​​the base station network, that is, a large number of terminals are connected to the communication network through the same base station. At this time, at the same time, there may be multiple terminals that simultaneously initiate RRC establishment requests to the base station. According to the technical solution of the embodiment of the present application, different types of terminals will respectively carry the reserved values ​​allocated to them in the reserved data bits in the RRC establishment request messages they send. In this way, after the base station receives the RRC establishment request messages sent by various types of terminals, it determines the network access priority of the corresponding terminal that initiated the RRC establishment request through the reserved values ​​in each received RRC establishment request message, and then responds to the RRC establishment request of each terminal in turn according to the network access priority of each terminal, and establishes an RRC connection with each terminal.

[0091] For example, when a first-type terminal sends an RRC establishment request message to a base station, another type of terminal also sends an RRC establishment request message to the base station. Furthermore, the other type of terminal also carries a reserved value in the pre-allocated reserved data bit in the sent RRC establishment request message, as described in the above embodiment. When the base station receives these RRC establishment request messages, it determines the network access priority of the different types of terminals based on the reserved values ​​in the messages. For the first-type terminal, if its network access priority is higher than that of the other types of terminals, the base station will prioritize responding to the RRC establishment request of the first-type terminal, thereby completing RRC establishment with the first-type terminal. If the network access priority of the first-type terminal is lower than that of the other types of terminals, the base station will prioritize responding to the RRC establishment request of the other types of terminals. After completing RRC establishment with the other types of terminals, the base station will respond to the RRC establishment request of the first-type terminal, thereby completing RRC establishment with the first-type terminal.

[0092] As an example, when the number of terminals in the target wireless cell requested to access the network by the above-mentioned first type terminal reaches the upper limit, if the first type terminal initiates an RRC establishment request to the base station to access the target wireless cell, then according to the technical solution of the above-mentioned embodiment of the present application, when the base station responds to the RRC establishment request of the first type terminal based on the network access priority of the first type terminal, it first selects a second terminal from the target wireless cell based on the network access priority of the first type terminal. The second terminal is a terminal with a lower network access priority than the first type terminal. Then, the base station disconnects the wireless connection with the second terminal and establishes an RRC connection with the first type terminal.

[0093] Specifically, according to the introduction of the above embodiments of the present application, when a terminal establishes an RRC connection with a base station, a reserved value is carried in the RRC establishment request message, so that the base station can determine the network access priority of the terminal that has entered the network or is requesting network access.

[0094] On this basis, if the number of terminals in the target wireless cell that the first type terminal requests to access has reached the upper limit, it is no longer possible for the first type terminal to directly establish an RRC connection with the target wireless cell. In this case, the base station selects a terminal with a lower network access priority than the first type terminal from the target wireless cell as the second terminal based on the network access priority of the first type terminal and the network access priorities of each terminal already in the target wireless cell, and disconnects the wireless connection with the second terminal. This will create a vacancy in the target wireless cell to allow the new terminal to access. At this time, the base station can respond to the RRC establishment request of the first type terminal and establish an RRC connection with the first type terminal.

[0095] Furthermore, in an embodiment of the present application, in addition to storing the network access priority information corresponding to each reserved value, the base station also stores a first identifier and a second identifier corresponding to each reserved value, wherein the first identifier is used to indicate whether it is allowed to preempt the network resources of other terminals, and the second identifier is used to indicate whether it is allowed to be preempted by other terminals.

[0096] Illustratively, in an embodiment of the present application, the base station stores the information shown in Table 1.

[0097] Table 1

[0098] Reserved value Seize resources Preempted Access priority Scheduling weight Spare1 Y N 6 100 Spare2 Y Y 5 90 Spare3 N Y 4 80 Spare4 N N 3 50 Spare5 Y Y 2 20 Spare6 N Y 1 10

[0099] As shown in Table 1, in addition to storing the access priority corresponding to each reserved value, the base station also stores the "preempted resource" flag, "preempted" flag and scheduling weight corresponding to each reserved value.

[0100] Among them, the "preempt resources" identifier, as the first identifier corresponding to the reserved value, is used to indicate whether the terminal type corresponding to the reserved value is allowed to preempt network resources of other terminals, N indicates that preempting network resources of other terminals is not allowed, and Y indicates that preempting network resources of other terminals is allowed; the "be preempted" identifier, as the second identifier corresponding to the reserved value, is used to indicate whether the terminal type corresponding to the reserved value is allowed to be preempted by other terminals for network resources, N indicates that preempting network resources by other terminals is not allowed, and Y indicates that preempting network resources by other terminals is allowed; the access priority table corresponding to the reserved value indicates the network access priority of the terminal type corresponding to the reserved value, and the larger the value of the access priority, the higher the network access priority; the scheduling weight corresponding to the reserved value is used to indicate the weight of the terminal type corresponding to the reserved value when being scheduled and allocated time-frequency resources by the base station, and the larger the scheduling weight corresponding to the reserved value, the greater the weight of the terminal type corresponding to the reserved value when being scheduled and allocated time-frequency resources by the base station.

[0101] Based on the above information storage, after the base station selects the second terminal from the target wireless cell, before disconnecting the wireless connection with the second terminal, it first determines whether the first type of terminal is allowed to preempt the network resources of other terminals and whether the second terminal is allowed to be preempted by other terminals based on the first identifier corresponding to the first reserved value and the second identifier corresponding to the second reserved value corresponding to the second terminal.

[0102] That is, based on the "grab resources" flag corresponding to the first reserved value corresponding to the first type of terminal, determine whether the first type of terminal is allowed to grab network resources of other terminals, and based on the "be grabbed" flag corresponding to the second reserved value corresponding to the second type of terminal, determine whether the second terminal is allowed to be grabbed by other terminals for network resources.

[0103] If the first type of terminal allows to preempt the network resources of other terminals, and the second terminal allows to be preempted by other terminals, the base station disconnects the wireless connection with the second terminal.

[0104] Otherwise, if the first type terminal is not allowed to seize network resources of other terminals, the base station can only wait for other terminals in the target wireless cell to actively disconnect from the target wireless cell, and then respond to the RRC establishment request of the first type terminal and establish an RRC connection with the first type terminal.

[0105] If the first type of terminal allows the network resources of other terminals to be preempted, but the second terminal does not allow the network resources to be preempted by other terminals, the base station needs to re-search other terminals as the second terminal and re-execute the above judgment until the second terminal selected by the base station allows the network resources to be preempted by other terminals, and then the base station disconnects the wireless connection with the second terminal.

[0106] The above processing process enables the base station to pre-determine the network access priority of different types of terminals, as well as the resource preemption priority of different types of terminals. In this way, the base station can not only determine the network access priority of the terminal according to the terminal type when the terminal accesses the network, thereby reasonably arranging the access of each terminal to the base station network, but also, when the base station network is fully loaded, allocate network resources to high-priority terminals according to the resource preemption priority of different types of terminals, thereby further realizing the priority processing of high-priority terminals and high-priority services, and further optimizing the utilization value of base station network resources.

[0107] Based on the above scheme, if a terminal has not been pre-allocated reserved data bits and has not been pre-allocated reserved values, then when the number of terminals in the target wireless cell that the terminal requests to access reaches the upper limit, if the terminal initiates an RRC establishment request to join the target wireless cell, the base station will reject the RRC establishment request of the terminal in accordance with the standard RRC rejection process.

[0108] From the above introduction, it can be seen that the terminal access control method proposed in the embodiment of the present application can store in the base station the reserved data bits allocated in advance for each terminal type in the establishment reason field of the RRC establishment request message, the reserved value allocated for each terminal type, and the access priority information corresponding to each reserved value. On this basis, when the first type of terminal sends an RRC establishment request message to the base station, the first reserved value is recorded in the first reserved data bit of the establishment reason field, wherein the first reserved data bit is the reserved data bit allocated for the first type of terminal in the establishment reason field, and the first reserved value is the reserved value allocated for the first type of terminal.

[0109] Correspondingly, the base station can determine the network access priority of the first type of terminal based on the first reserved data bit, the first reserved value, and the access priority information corresponding to the first reserved value in the received RRC establishment request message, and then respond to the RRC establishment request of the first type of terminal based on the network access priority of the first type of terminal.

[0110] The above solution enables the base station to clarify the priority of the terminal when establishing an SRB with the terminal, and establish the SRB with the terminal according to the terminal priority, so that the terminal with a high priority can have priority in establishing the SRB.

[0111] Furthermore, as shown in Table 1, in addition to storing the network access priority information corresponding to each reserved value, the base station also stores the scheduling weight information corresponding to each reserved value.

[0112] See also Figure 2 As shown, after the base station executes step S104 to establish an RRC connection with the first type of terminal, it also executes step S105 to allocate time-frequency resources to the first type of terminal according to the scheduling weight information corresponding to the first reserved value.

[0113] Specifically, the base station constructs a first scheduling queue in descending order of scheduling weights according to the scheduling weight information corresponding to the first reserved value of the first type of terminal and the scheduling weight information corresponding to other terminals to which resources are currently to be allocated.

[0114] The first type of terminals and other terminals to be allocated resources are sorted in descending order of scheduling weight based on the scheduling weight information corresponding to their respective reservation values ​​to form a terminal queue. The terminals with the top N scheduling weights are then selected from the terminal queue to form a first scheduling queue, where N is a positive integer.

[0115] The base station first allocates time domain resources to terminals in the first scheduling queue. If no RLC layer resources are received for a terminal in the first scheduling queue during the processing period for allocating time domain resources for the first scheduling queue, the terminal is removed from the first scheduling queue and placed in a subsequent scheduling queue for resource allocation.

[0116] For each terminal in the first scheduling queue that is allocated time domain resources, within each time domain resource interval, that is, within a TTI, frequency domain resources are allocated to each terminal according to the scheduling weight information of each terminal in the video resource interval.

[0117] Specifically, within a TTI, each terminal to which the TTI resources are allocated is allocated frequency domain resources within the TTI according to the scheduling weight of each terminal.

[0118] For example, assuming that two terminals are allocated in the same TTI, and the scheduling weights of the two terminals are 50 and 100 respectively, then in the TTI, the frequency domain resources in the TTI are allocated to the two terminals at a ratio of 50:100.

[0119] In addition, during the frequency domain resource allocation process described above, the terminal's QCI can also be considered for resource allocation. For example, if some terminals within the same TTI are not assigned scheduling weights, frequency domain resources can be allocated to these terminals based on their QCIs. If terminals within the same TTI are assigned both scheduling weights and corresponding QCIs, frequency domain resources can be allocated to each terminal based on the scheduling weights as described in the above embodiment. Alternatively, frequency domain resources can be allocated to each terminal based on a combination of scheduling weights and QCIs.

[0120] For example, assuming that within the same TTI, the scheduling weight of terminal A is 100 and the QCI is 10; the scheduling weight of terminal B is 50 and the QCI is 5, then To calculate and determine the allocation ratio of the frequency domain resources of the two terminals within the TTI, or by The allocation ratio of the frequency domain resources in the TTI to the two terminals is calculated and determined, and then the frequency domain resources in the TTI are allocated to the two terminals according to the allocation ratio of the frequency domain resources in the TTI.

[0122] S201. Send an RRC establishment request message including an establishment cause field to a base station, where a first reserved data bit of the establishment cause field contains a first reserved value, wherein the first reserved data bit is a reserved data bit allocated in the establishment cause field for the first type of terminal, and the first reserved value is a reserved value allocated for the first type of terminal;

[0123] The RRC establishment request information is used to trigger the base station to determine the network access priority of the first type of terminal according to the first reserved data bit and the first reserved value.
