Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.

The FAPI interface between the physical layer L1 and the medium access control layer L2 of the existing 4G,5G base station and the signaling/data of the medium access control layer L2 and the wireless resource control layer L3 do not carry the identification of the receiving and transmitting equipment, and the received data cannot identify the receiving equipment of the receiving equipment at a high layer, namely cannot inquire the receiving position area of the data, so the prior art cannot realize the admission control of a smaller granularity range.

In some technologies, multiple sets of access control parameters are configured for user terminals UE of the same access class according to network resource conditions, so as to implement priority to allow certain user terminals UE initiating an access procedure to access a network, which is essential for improving the network resource utilization rate. Access control for the location of the user terminal UE cannot be achieved. In some technologies, according to the identification of the base station registration information, if the base station is in an illegal area, the base station is forbidden to access the core network, so that the base station cannot serve the user under the small base station, which is a control access method of the base station, and cannot accurately perform area access control on the user terminal UE. So at present, the admission control method for prohibiting or allowing the UE to access to the appointed transceiver equipment under the scenes of multi-transceiver equipment (such as AAU/RU/RRU/O-RU/PRRU/RRH/TRP/RFU/head end and the like) of a large coverage area cell, a building stereo cell and the like cannot be solved. There is a problem in that the range of admission control is too large, and smaller granularity of admission control based on location areas cannot be achieved. Thus, an admission control method of smaller granularity range (based on location area) is proposed.

The refined admission control method based on the location area has wider application, such as:

( 1) Broad coverage planar cells (e.g.: manufacturing plant, mine )

1) The equipment robot of the installation terminal is limited to work in a designated workshop and area, can be disconnected when moving out of an authorized range, and gives an alarm to a system, informs an administrator of timely processing, and avoids safety accidents; as shown in fig. 1, the base station admission control method based on the location area and the transceiver device of the present application can realize that the user terminal UE-1 can only access the location area of Region-5, and can also realize that the user terminal UE-1 is prohibited from accessing the location area of Region-5, and allow to access other location areas except the location area of Region-5, as shown in fig. 2.

2) Specific areas such as a core manufacturing area and the like prohibit unauthorized terminals from accessing, such as security accidents such as secret leakage caused by incapacity of a (camera) terminal device to transmit data, serious damage caused by entry of equipment invaded by a hacker and the like;

(2) Building three-dimensional district (e.g. bank, secret related unit)

1) Based on the security factor, the vault/core security area can only limit the access of high-level authorized terminals, and the terminals in the area not can not be accessed;

2) The security or different functional departments have different jurisdiction division, the distributed terminals can only be used in the jurisdiction of the users, and the terminals which are accessed are refused to be accessed or released when the distributed terminals exceed the area range, so that security accidents and terminal secret leakage events are avoided;

the application relates to a base station admittance control method based on a location area and a receiving and transmitting device, which comprises the steps of firstly configuring a relation table for a base station, wherein the relation table comprises the location area, the receiving and transmitting device identification and actions, and the actions comprise the admission or refusal of the access, and the specific process is as follows:

after the transceiver is powered on and started, a registration request is initiated to a configuration management module OM of the base station, the configuration management module OM distributes a unique transceiver identifier device_ID of the base station to each transceiver, and the transceiver identifier is written into a configured relation table and can be directly used next time.

As shown in table 1, each location area includes one or more transceiver devices, and each location area corresponds to an action, and the configuration relationship table is as follows:

TABLE 1 location area and Transceiver configuration relationship Table

As shown in table 2-table 3, the relationship table may further include a time period and/or a user terminal identifier, and an action value is assigned to the location area according to the time period; as shown in table 2, a time period is added to the configured relationship table.

Table 2 configuration relation table containing time slots

As shown in table 3, a user terminal identifier ue_id is added to the configured relationship table;

TABLE 3 configuration relationship table of location area and transceiver

The receiving and transmitting equipment receives uplink data of a user terminal (UE), and a physical layer of a base station transmits the uplink data to a media access control layer (L2) of the base station; a field of a transceiver equipment identification list is added in a FAPI interface between a physical layer and a media access control layer L2 and is used for carrying one or more transceiver equipment Port numbers RU_Port_ID;

the media access control layer L2 or the radio resource control layer L3 of the base station is based on the configured relation table; and acquiring an Action corresponding to the Region zone_ID of the receiving and transmitting equipment, searching whether the user terminal UE is associated with the Region zone_ID, outputting a judging result according to Action actions configured by the user terminal UE if the judging result exists, outputting a judging result according to default Action actions in the Region if the judging result does not exist, and outputting a judging result according to default actions of a cell if the position Region does not exist, wherein the flow chart is shown in figure 2.

Outputting a judging result based on the action corresponding to the position area; the base station allows access to the user terminal UE in the location area based on the determination result, or the base station denies access to the user terminal UE in the location area based on the determination result.

Example 1

In the LTE scenario, the UE initiates random access, if the area where the transceiver of the eNB is located configures the area to prohibit access of all UEs within a specified time period (or other policies), a policy that allows access of all UEs within the current time period may be configured in the relationship table, where the configuration of the relationship table is managed by the user; at this time, the user terminal identifier ue_id does not need to be identified, after the base station eNB receives the first signaling MSG1 sent by the user terminal UE, the media access control layer L2 of the base station eNB directly refuses the access of the user terminal UE through the second signaling MSG2, and the user terminal UE does not need to wait until the third signaling MSG3 and even the fifth signaling MSG5 are interacted and refused, so that the fastest refusing is realized; as shown in fig. 4, the specific implementation steps are as follows:

step 101, a network management system configures a relation table for a base station eNB, wherein action values are assigned to a location area according to time periods, all user terminals (UE) are forbidden to access in a certain time period in an area where a transceiver device is located, and the relation table is shown in a table 2;

step 102, the transceiver receives the Preamble data sent by the UE, and sends the Preamble data to the physical layer of the base station through an eCPRI interface message of the uplink data interface, where the eexc_id cell in the eCPRI data interface carries the number ru_port_id of the Port of the transceiver to indicate from which transceiver the Preamble is received;

Step 103, the physical layer L1 of the base station receives Preamble data of the UE received by one or more transceivers, after the combining process, the Preamble data and the Port number ru_port_id of the transceivers are filled into the rach.indication or nb_harq.indication interface in the SCF082 LTE FAPI interface, and a field "device_id List" field of the transceiver identifier List is newly added in the rach.indication or nb_harq.indication, and is used for carrying the Port number ru_port_id of one or more transceivers, where the Port number ru_port_id of the transceivers is used as a transceiver identifier;

in step 104, the medium access control layer L2 of the base station eNB receives the uplink data of the rach. Indication or nb_harq. Indication interface, where the uplink data includes a transceiving equipment identifier List device_id List, reads the configuration of the network management system, queries the current time of the area where the user terminal UE is located through the transceiving equipment identifier List device_id List to prohibit all the user terminal UE from accessing, adds a backoff indication information unit BI (Backoff Indicator) in the second signaling MSG2 (RAR) to indicate the waiting time for the user terminal in the location area to initiate access again, and the backoff indication information unit BI may be configured.

The embodiment has the beneficial effects that the user terminal UE initiates the initial random access to LTE system request, the base station eNB directly refuses all user terminal UEs to access after receiving the first signaling MSG1, and the base station does not need to wait for the third signaling MSG3 when the access refusing is advanced to the second signaling MSG2 stage, so that the method has the fastest response and the highest performance.

Example two

In the LTE scenario, the UE initiates random access, if the area where the transceiver of the eNB is located configures the area to prohibit access of all UEs within a specified time period (or other policies), a policy that allows access of all UEs within the current time period may be configured in the relationship table, where the configuration of the relationship table is managed by the user; at this time, the identification of the user terminal UE does not need to be identified, after the eNB receives the third signaling MSG3 sent by the user terminal UE, the base station eNB media access control layer L2 refuses the access of the user terminal UE, so that the interaction with the radio resource control layer L3 message is reduced, and a faster admission response is realized. As shown in fig. 5, the specific implementation steps are as follows:

step 201, the network management system configures a relation table for the base station eNB, wherein the action value is assigned to the location area according to time periods, and the area where the transceiver equipment is located prohibits all user terminals UE from accessing in a certain time period, and the relation table is shown in table 2;

Step 202, in the third signaling MSG3 stage, the physical layer of the base station receives uplink data of the UE received by one or more transceivers, and after the combining process, fills the uplink data and the Port number ru_port_id of the transceivers into an rx_ulsch.indication interface in the SCF082 LTE FAPI interface, and adds a field "device_id List of the transceiver identifier" in the rx_ulsch.indication, which is used to carry the Port number ru_port_id of one or more transceivers;

in step 203, the medium access control layer L2 of the base station eNB receives the uplink data including the third signaling MSG3, the uplink data includes a transceiver Device identifier List, and reads the configuration of the network management system, and the access of all the user terminals UE is prohibited at the current time in the area where the user terminals UE are located by querying the transceiver Device identifier List device_id List in the uplink data, and the medium access control layer L2 of the base station sends the RRCConnectionReject signaling to the user terminals UE in the area of the location, thereby rejecting the access of the user terminals UE.

The embodiment has the advantages that the user terminal UE initiates an initial random access to LTE system request, the base station eNB receives the third signaling MSG3 according to the relation table by the media access control layer L2 and then refuses the user terminal UE to access, and the user terminal UE does not need to wait until interaction with the mobile management entity MME, so that signaling interaction with the user terminal UE and the mobile management entity MME is reduced, and better performance is achieved; and the rejection flow is advanced to the processing of the media access control layer L2, so that the signaling interaction between the media access control layer L2 and the radio resource control layer L3 is reduced, and the performance is higher than that of the rejection of the radio resource control layer L3.

Example III

In the LTE scenario, the UE initiates random access, if the area where the transceiver of the eNB is located configures the area to prohibit access of all UEs within a specified time period (or other policies), a policy that allows access of all UEs within the current time period may be configured in the relationship table, where the configuration of the relationship table is managed by the user; at this time, the ue_id does not need to be identified, and after the base station eNB receives the third signaling MSG3 sent by the UE, the base station eNB radio resource control layer L3 denies access to the UE, as shown in fig. 6, and the specific implementation steps are as follows:

step 301, the network management system configures a relation table for the base station eNB, wherein the location area is assigned with action values according to time periods, and the area where the transceiver equipment is located is forbidden to be accessed by all user terminals UE in a certain time period, and the relation table is shown in table 2;

step 302, in the third signaling MSG3 stage, the physical layer of the base station receives uplink data of the UE received by one or more transceivers, and after the combining process, fills the uplink data and the Port number ru_port_id of the transceivers into an rx_ulsch.indication interface in the SCF082 LTE FAPI interface, and adds a field "device_id List" of the transceiver identifier in the rx_ulsch.indication, which is used to carry the Port number ru_port_id of one or more transceivers;

Step 303, the base station eNB media access control layer L2 receives the uplink data including the third signaling MSG3, and sends the device_id List and MSG3 in the uplink data to the radio resource control layer L3, where the field is newly added in the uplink control signaling UL-CCCH-Message carrying the third signaling MSG3, where the field is a "transceiver equipment identifier List device_id List" and is used to carry the Port numbers ru_port_id of one or more transceivers;

step 304, the radio resource control layer L3 reads the relation table, and inquires through a transceiving equipment identification List device_id List in the uplink data that all user terminals UE are forbidden to access at the current moment in the area where the user terminals UE are located, and then the radio resource control layer L3 sends an RRCConnectionReject signaling to the user terminals UE in the location area, and denies the access of the user terminals UE;

the embodiment has the advantages that the user terminal UE initiates an initial random access to LTE system request, the base station eNB refuses the access of all the user terminals UE by the radio resource control layer L3 according to the relation table, and the refusing flow is put into the radio resource control layer L3 for processing, so that the method is more in line with the architecture of uniform admission control of the radio resource control layer L3;

example IV
