Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of emergency communication base station, and particularly relate to a connection establishment method and device for a backpack type base station and the backpack type base station. BACKGROUND

[0002] The base station is an interface device for mobile devices to access the Internet, and refers to a radio transceiver station that performs information transmission between mobile telephone terminals and mobile communication switching centers in a certain radio coverage area.

[0003] When a sudden event such as a natural disaster occurs, the original base station in the area where the sudden event occurs is damaged, the network communication in the area is blocked, and the personnel to be rescued cannot successfully send rescue information, which is not conducive to the timely and smooth development of rescue work. Based on this, the backpack type base station emerges as the times require. How to provide communication services for terminals of different operators through the backpack type base station becomes a problem to be solved. SUMMARY

[0004] In view of the above problems, embodiments of the present application provide a connection establishment method and device for a backpack type base station and the backpack type base station. The backpack type base station can not only establish communication connections with terminals of multiple operators in the area where a sudden event occurs, but also can meet the needs of most terminals for network and relieve network pressure.

[0005] In a first aspect, a connection establishment method for a backpack type base station is provided. The backpack type base station is in communication connection with core network devices of multiple operators. The method comprises the following steps:

[0006] Obtaining quantity information of terminals of each operator in a target area, the target area being a signal coverage area of the backpack type base station; sending broadcast information based on the quantity information and a predetermined rule, the broadcast information at least containing public land mobile network identifiers (PLMN IDs) of the multiple operators; wherein the PLMN IDs of the multiple operators are determined according to operator information to which different terminals in the target area belong, the target area being a signal coverage area of the backpack type base station; receiving an access request sent by a target terminal, the access request being sent by the target terminal after listening to the broadcast information containing the PLMN ID of the operator to which the target terminal belongs; and sending an access response to the target terminal to establish a communication connection with the target terminal.

[0007] According to the above scheme, the broadcast information sent by the backpack-type base station contains the PLMN IDs of multiple operators, and the PLMN IDs of the multiple operators are determined according to the operator information to which the terminals in the target area belong. Therefore, no matter which operator the terminal in the target area belongs to, the terminal can send an access request to the backpack-type base station when it is determined that the broadcast information listened to contains the PLMN ID of the operator to which the terminal belongs. The backpack-type base station can establish connections with different terminals of multiple operators in the target area (the area where the burst situation occurs) based on the received access request sent by the target terminal, so as to facilitate the terminals of multiple operators in the target area to communicate through the backpack-type base station and the core network device of the corresponding operator. In addition, the backpack-type base station can send different broadcast information in different time periods based on the quantity information and the predetermined rule. In this way, the demand of most terminals for the network can be met, and the network pressure can be relieved.

[0008] In some embodiments, the sending of the broadcast information based on the quantity information and the predetermined rule comprises: sorting the operators to which the terminals belong in descending order of the quantity information to obtain an operator sequence; and sending, based on the operator sequence, broadcast information carrying the PLMN ID of the operator corresponding to the i-th sequence in the i-th time period, and sending broadcast information carrying the PLMN ID of the operator corresponding to the (i+1)-th sequence in the (i+1)-th time period; wherein i is an integer greater than 0, and the i-th time period is earlier than the (i+1)-th time period.

[0009] According to the above scheme, the backpack-type base station can send broadcast information carrying the PLMN ID of the operator corresponding to the operator with a higher sequence in the earlier time period, and send broadcast information carrying the PLMN ID of the operator corresponding to the operator with a lower sequence in the later time period, in other words, the backpack-type base station can send broadcast information carrying the PLMN ID of the operator in the time periods in the order of sequence. In this way, the terminals of the operator with a higher sequence can preferentially access the backpack-type base station and the core network device of the corresponding operator to implement communication, and the terminals of the operator with a lower sequence can access the backpack-type base station and the core network device of the corresponding operator to implement communication later. The demand of most terminals for the network can be met, and the network pressure can be relieved.

[0010] In some embodiments, the length of the i-th time period is greater than the length of the (i+1)-th time period.

[0011] By the above scheme, the sending time length of the broadcast information carrying the PLMN ID corresponding to the operator with a high ranking is longer, and the sending time length of the broadcast information carrying the PLMN ID corresponding to the operator with a low ranking is shorter. When the operator with a high ranking is an operator with a large number of terminals, and the operator with a low ranking is an operator with a small number of terminals, the sending time length of the broadcast information is set in this way, which not only ensures that the terminals of the operator with a high ranking have enough time to receive the broadcast information, but also reduces unnecessary resource waste caused by the long sending time length of the backpack-type base station sending the broadcast information carrying the PLMN ID corresponding to the operator with a low ranking.

[0012] In some embodiments, after receiving the access request sent by the target terminal, the method further includes: determining the number of terminals currently accessing the backpack-type base station; and sending an access response to the target terminal when the number of terminals currently accessing the backpack-type base station is less than a first number threshold.

[0013] By the above scheme, the backpack-type base station allows the target terminal to access the backpack-type base station only when it is determined that the number of terminals currently accessing the backpack-type base station is less than the first number threshold. In this way, the possibility of communication congestion can be reduced by limiting the number of terminals accessing the backpack-type base station, thereby facilitating the guarantee of good communication quality.

[0014] In some embodiments, after receiving the access request sent by the target terminal, the method further includes: determining the number of terminals currently accessing the backpack-type base station; and sending an access response to the target terminal when the number of terminals currently accessing the backpack-type base station is less than a first number threshold.

[0015] By the above scheme, the number of terminals accessible by each target operator is set to a corresponding second number threshold according to the capacity of the backpack-type base station to access terminals. The backpack-type base station allows the target terminal to access the backpack-type base station only when it is determined that the number of terminals of the target operator currently accessing the backpack-type base station is less than the second number threshold. In this way, the possibility of communication congestion can be reduced by limiting the number of terminals of the target operator allowed to access the backpack-type base station, thereby facilitating the guarantee of good communication quality.

[0016] The second aspect of the embodiments of the present application provides a connection establishment apparatus for a backpack-type base station in communication connection with core network devices of a plurality of operators, the apparatus comprising:

[0017] The acquisition module is configured to acquire the number information of terminals of each operator in a target area, the target area being a signal coverage area of the backpack-type base station.

[0019] The receiving module is configured to receive an access request sent by the target terminal, the access request being sent by the target terminal after determining that the broadcast information contains the PLMN ID of the operator to which the target terminal belongs.

[0020] The responding module is configured to send an access response to the target terminal to establish a communication connection with the target terminal.

[0021] In some embodiments, the sending module is specifically configured to: sort the operators to which the terminals belong in a descending order of the quantity information to obtain an operator sequence; send, based on the operator sequence, the broadcast information carrying the PLMN ID of the operator with the i-th sequence in the i-th time period, and send the broadcast information carrying the PLMN ID of the operator with the (i+1)-th sequence in the (i+1)-th time period; wherein i is an integer greater than 0, and the i-th time period is earlier than the (i+1)-th time period.

[0022] In some embodiments, the length of the i-th time period is greater than the length of the (i+1)-th time period.

[0038] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0039] Figure 1 This is a flowchart illustrating a connection establishment method for a backpack-type base station, provided in an embodiment of this application. The method is applied to the backpack-type base station, which communicates with core network equipment from multiple operators. It should be noted that the backpack-type base station provided in this embodiment can provide communication assurance for terminals in areas experiencing emergencies (i.e., the target area), ensuring stable network operation in that target area. Emergencies can include disasters such as earthquakes, mudslides, and floods. Furthermore, terminals include, but are not limited to, mobile phones, personal digital assistants (PDAs), tablets, and portable devices (e.g., laptops, pocket computers, or handheld computers) with communication capabilities.

[0040] like Figure 1As shown, the connection establishment method for a backpack-type base station in this embodiment may include the following steps.

[0041] Step 101: Obtain the number of terminals of each operator in the target area, which is the signal coverage area of ​​the backpack base station.

[0042] The operators to which different terminals belong within the target area may include a first operator, a second operator, a third operator, etc. This application does not limit the types of operators to which different terminals belong within the target area. However, for ease of description, this application will only use the first operator, the second operator, and the third operator as examples for illustration, but this does not constitute a limitation on the scope of application of this application.

[0043] Information on the number of terminals of each operator in the target area may include, for example, the number of terminals of the first operator, the number of terminals of the second operator, and the number of terminals of the third operator in the target area.

[0044] Step 102: Send broadcast information based on quantity information and predetermined rules.

[0045] The broadcast information includes at least the Public Land Mobile Network IDs (PLMNs) of multiple operators, and the PLMNs of multiple operators are determined based on the operator information of different terminals in the target area.

[0046] The pre-set rules can be rules for sending broadcast information in advance. These pre-set rules can include the order in which broadcast information containing different PLMN IDs is sent, the duration of the broadcast information containing different PLMN IDs, etc.

[0047] A PLMN ID is a network identifier established for the purpose of providing terrestrial mobile communication services to the public, and each operator has its own unique PLMN ID. In this step, to facilitate communication between terminals of different operators via the backpack base station, multiple operators' PLMN IDs can be broadcast. These multiple operator PLMN IDs are determined based on the operator information of different terminals within the target area, which is the signal coverage area of ​​the backpack base station.

[0048] Step 102 can be achieved through, for example... Figure 2 This is achieved through steps 1021 and 1022 shown.

[0049] Step 1021: Sort the terminal operators according to the order of quantity information from largest to smallest to obtain the operator ranking.

[0050] When the operators to which different terminals in the target area belong include the first operator, the second operator, and the third operator, and the number of terminals is the number of terminals, sorting the number of terminals of these three operators in descending order may result in the following situations:

[0051] In the first scenario, if the number of terminals from these three operators is the same, then these three operators are ranked equally, with a total of 1. In other words, there is no specific order among these three operators.

[0052] In the second scenario, two of the three operators have the same number of terminals, but the number of terminals differs from that of the remaining operator. For example, suppose the first and second operators each have 10 terminals in the target area, and the third operator has 5 terminals. Since 10 > 5, the operator ranked 1st in the resulting operator ranking is the first and second operators, and the operator ranked 2nd is the third operator.

[0053] In the third scenario, the number of terminals from these three operators is different. For example, suppose the number of terminals from the first operator in the target area is 10, the number of terminals from the second operator is 8, and the number of terminals from the third operator is 5. Since 10 > 8 > 5, the operator ranked 1st is the first operator, the operator ranked 2nd is the second operator, and the operator ranked 3rd is the third operator.

[0054] Step 1022: Based on the operator sorting, send a broadcast message carrying the PLMN ID corresponding to the operator sorted as i in the i-th time period, and send a broadcast message carrying the PLMN ID corresponding to the operator sorted as i+1 in the i+1 time period.

[0055] Where i is an integer greater than 0, and the i-th time period is earlier than the (i+1)-th time period.

[0056] Continuing with the example of the first scenario above, when these three operators are ranked as number 1, the backpack-type base station can send broadcast information carrying the PLMN IDs of these three operators in the first time period. In other words, broadcast information carrying the PLMN IDs of these three operators is sent simultaneously within the same time period. In this way, terminals of these three operators can simultaneously access the backpack-type base station, thereby enabling communication with the core network equipment of their respective operators through the backpack-type base station.

[0057] Continuing with the example of the second scenario above, when the operators ranked 1 are the first and second operators, and the operator ranked 2 is the third operator, the backpack base station can send broadcast information carrying the PLMN IDs corresponding to the first and second operators in the first time period, and broadcast information carrying the PLMN IDs corresponding to the third operator in the second time period. In this way, terminals from a larger number of operators can preferentially access the backpack base station and the corresponding operator's core network equipment to communicate, thus meeting the network needs of most terminals.

[0058] Continuing with the example of the third scenario above, when the operator ranked 1 is the first operator, the operator ranked 2 is the second operator, and the operator ranked 3 is the third operator, the backpack-type base station can send broadcast information carrying the PLMN ID corresponding to the first operator in the first time period, broadcast information carrying the PLMN ID corresponding to the second operator in the second time period, and broadcast information carrying the PLMN ID corresponding to the third operator in the third time period. This allows a larger number of terminals from different operators to preferentially access the backpack-type base station and the corresponding operator's core network equipment to achieve communication, meeting the network needs of most terminals.

[0059] In this embodiment, the backpack-type base station can, based on the obtained operator ranking, send broadcast information carrying the PLMN IDs of operators ranked higher in the earlier time periods and broadcast information carrying the PLMN IDs of operators ranked lower in the later time periods. In other words, the backpack-type base station can send broadcast information carrying the PLMN IDs of operators in time periods according to a chronological order. In this way, terminals of operators ranked higher can preferentially access the backpack-type base station and communicate with the corresponding operator's core network equipment, while terminals of operators ranked lower can access the backpack-type base station and communicate with the corresponding operator's core network equipment later. This satisfies the network needs of most terminals while alleviating network pressure.

[0060] It is worth noting that, in this embodiment, the terminal's operator can be sorted not only in descending order of quantity information as in step 1011, but also in ascending order of quantity information. When sorting the terminal's operator in ascending order of quantity information, the order of sending broadcast information is simply the reverse of the order described in step 1012. This embodiment does not limit the method of sorting the terminal's operator.

[0061] In some embodiments, the duration of the i-th time period can be set to be greater than the duration of the (i+1)-th time period.

[0062] The duration of the i-th time period is longer than the duration of the (i+1)-th time period. This allows for a longer transmission time for broadcast messages carrying the PLMN IDs of operators with higher rankings, and a shorter transmission time for broadcast messages carrying the PLMN IDs of operators with lower rankings. When the operators with higher rankings have a larger number of terminals, and the operators with lower rankings have a smaller number of terminals, setting the broadcast message transmission time in this way not only ensures that terminals of the operators with higher rankings have sufficient time to receive broadcast messages, but also reduces unnecessary resource waste caused by the backpack base station transmitting broadcast messages carrying the PLMN IDs of operators with lower rankings for a longer duration.

[0063] After sending the broadcast message, proceed to step 103:

[0064] Step 103: Receive the access request sent by the target terminal. The access request is sent by the target terminal after it has determined that the broadcast information it has been listening to contains the PLMN ID of its own operator.

[0065] It should be noted that terminals whose PLMN ID is included in the broadcast information are target terminals, and target terminals can send access requests to the backpack base station. Terminals whose PLMN ID is not included in the broadcast information are not target terminals, and non-target terminals cannot send access requests to the backpack base station.

[0066] When the backpack base station sends broadcast information in step 102, terminals located within the target area can listen to the broadcast information sent by the backpack base station. Subsequently, the terminals within the target area can parse the listened broadcast information and determine whether it contains the PLMN ID of their own operator. For example, the terminals within the target area can extract each PLMN ID contained in the parsed broadcast information and then compare each PLMN ID with the PLMN ID of their own operator. If the comparison finds that a certain PLMN ID in the broadcast information is the same as the PLMN ID of their own operator, it is determined that the listened broadcast information contains the PLMN ID of their own operator, and the terminal is the target terminal. Subsequently, the target terminal can send an access request to the backpack base station. Correspondingly, the backpack base station can receive the access request sent by the target terminal.

[0067] To alleviate the processing burden on backpack base stations, in some embodiments, after receiving the access request sent by the target terminal in step 103, the backpack base station can directly send an access response to the target terminal in step 104 to establish a communication connection with the target terminal.

[0068] Of course, in other embodiments, the access request may carry the PLMNID of the operator to which the target terminal belongs. When the backpack base station receives the access request sent by the target terminal, it can first determine whether the target terminal sending the access request has permission to access the backpack base station based on the PLMNID carried in the access request. For example, the backpack base station can compare the PLMN ID carried in the access request with the PLMN ID included in the broadcast information. If the PLMN ID carried in the access request is a PLMN ID included in the broadcast information, then it is determined that the target terminal sending the access request has permission to access the backpack base station. When it is determined that the target terminal sending the access request has permission to access the backpack base station, an access response is sent to the target terminal through the following step 104 to establish a communication connection with the target terminal. In this way, the possibility of mistakenly accessing the backpack base station as a target terminal can be reduced.

[0069] Step 104: Send an access response to the target terminal to establish a communication connection with the target terminal.

[0070] After a backpack-type base station connects a target terminal to the base station based on an access request, it sends an access response to the target terminal. This allows the target terminal to promptly know that it has successfully connected to the backpack-type base station, thus enabling it to stop sending further access requests to the base station in a timely manner.

[0071] Backpack-type base stations communicate with the core network equipment of multiple operators. After the backpack-type base station establishes a communication connection with the target terminal, the target terminal can communicate with the core network equipment of the operator to which the target terminal belongs through the backpack-type base station.

[0072] For example, if the backpack base station establishes a communication connection with a terminal of the first operator based on an access request, the backpack base station can operate on the frequency band of the first operator, enabling the first operator's terminal to communicate with the first operator's core network equipment in the target area via the backpack base station. In this way, the first operator's terminal can successfully send distress signals or other communication information out of the target area.

[0073] It is worth noting that after receiving the access request from the target terminal in step 103, the backpack base station can directly connect the target terminal to the backpack base station without performing any judgment steps, and send an access response to the target terminal as in step 104 to establish a communication connection with the target terminal. Of course, after receiving the access request from the target terminal in step 103, the backpack base station can at least perform some judgment steps as in the following two embodiments, and only send an access response to the target terminal in step 104 when it is determined that the actual access status of the terminal in the current backpack base station meets certain conditions.

[0074] In some embodiments, after receiving an access request from a target terminal, the backpack base station can determine the number of terminals currently connected to the backpack base station. If the number of terminals currently connected to the backpack base station is less than a first threshold, an access response is sent to the target terminal.

[0075] It should be noted that the first quantity threshold is the maximum number of terminals that a backpack-type base station can allow to access.

[0076] Each time a backpack-type base station allows a terminal to access the network, it updates the number of terminals already connected to the base station. For example, it can increment the number of connected terminals by one to obtain the current number of connected terminals. Subsequently, when the backpack-type base station receives an access request from a target terminal, it can compare the current number of connected terminals with a first threshold to determine whether to allow the target terminal that sent the access request to access the base station. If it determines to allow the target terminal that sent the access request to access the base station, it sends an access response to it.

[0077] On the one hand, if it is determined that the number of terminals currently connected to the backpack-type base station is less than a first threshold, it indicates that the backpack-type base station still has the capacity to provide access for the target terminal. Therefore, the target terminal can be connected to the backpack-type base station based on the access request. After access, an access response can be sent to the target terminal so that the target terminal can be promptly notified of successful access and thus stop sending access requests to the backpack-type base station.

[0078] On the other hand, if it is determined that the number of terminals currently connected to the backpack base station is greater than or equal to a first threshold, it indicates that the backpack base station has no spare channels for the target terminal to access, and therefore the target terminal can be temporarily denied access. To facilitate timely notification of access failure to the target terminal and thus prompt it to stop sending access requests to the backpack base station, the backpack base station can send an access failure notification to the target terminal while refusing access. Optionally, the temporarily denied target terminal can access the backpack base station during its subsequent idle time.

[0079] In this embodiment, the backpack base station only allows the target terminal to access the backpack base station when it determines that the number of terminals currently connected to the backpack base station is less than a first quantity threshold. In this way, the possibility of communication congestion can be reduced by limiting the number of terminals connected to the backpack base station, which helps to ensure good communication quality.

[0080] In other embodiments, after receiving an access request from a target terminal, the backpack base station can also determine the number of terminals of the target operator currently connected to the backpack base station, where the target operator is the operator to which the target terminal belongs. If the number of terminals of the target operator currently connected to the backpack base station is less than a second threshold, an access response is sent to the target terminal.

[0081] It should be noted that the second quantity threshold is the threshold for the number of terminals of the target operator allowed to access the backpack base station. The second quantity threshold set for different target operators can be the same or different. Optionally, different second quantity thresholds can be set based on the number of terminals of each target operator in the target area. For example, if the number of terminals of the first operator is larger than that of the third operator in the target area, then the second quantity threshold set for terminals of the first operator can be larger than the second quantity threshold set for terminals of the third operator.

[0082] Each time a backpack-type base station allows a terminal from a different operator to access the base station, it updates the number of terminals from that operator already connected, enabling separate statistics on the number of terminals from each operator connected to the base station. For example, when the backpack-type base station allows a terminal from the first operator to access the base station, it increments the number of terminals from the first operator already connected to the base station by one, obtaining the current number of terminals from the first operator already connected to the base station. Subsequently, when the backpack-type base station receives an access request from a target terminal, it compares the current number of terminals from the target operator already connected to the base station with a second threshold number to determine whether to allow the target terminal that sent the access request to access the base station and sends an access response to it.

[0083] For example, suppose the second quantity threshold set for terminals of the first operator is 20, the second quantity threshold set for terminals of the second operator is 14, and the second quantity threshold set for terminals of the third operator is 10. Currently, the number of terminals of the first operator that have been connected to the backpack base station is 15, the number of terminals of the second operator that have been connected to the backpack base station is 14, and the number of terminals of the third operator that have been connected to the backpack base station is 9.

[0084] If the backpack base station receives an access request from a terminal of the first operator, it can compare the second quantity threshold set for the first operator's terminals with the number of first operator's terminals currently connected to the backpack base station. Since 15 < 20, the backpack base station can connect the first operator's terminal to the backpack base station and send an access response to it. Similarly, if the backpack base station receives an access request from a terminal of the second operator, since 14 = 14, the backpack base station will not connect the second operator's terminal to the backpack base station. If the backpack base station receives an access request from a terminal of the third operator, since 9 < 10, the backpack base station can connect the third operator's terminal to the backpack base station and send an access response to it.

[0085] In this embodiment, based on the number of terminals that the backpack base station can access, a corresponding second threshold is set for the number of terminals that each target operator can access. The backpack base station only allows a target terminal to access the backpack base station when it determines that the number of terminals of the target operator currently connected to the backpack base station is less than the second threshold. In this way, the possibility of communication congestion can be reduced by limiting the number of terminals of the target operator allowed to access the backpack base station, thus ensuring good communication quality.

[0086] Furthermore, by setting different second quantity thresholds for the number of terminals from different target operators allowed to access the backpack-type base station, resources corresponding to the quantity of terminals from different target operators can be allocated. This can reduce the occurrence of communication congestion for terminals from some operators while terminals from other operators have surplus communication resources. While ensuring good communication quality for terminals from each target operator, resources can also be allocated and utilized reasonably and effectively.

[0087] The connection establishment method for a backpack base station provided in this application embodiment includes broadcast information from the backpack base station containing PLMN IDs of multiple operators. These PLMN IDs are determined based on the operator information of different terminals within the target area. This ensures that regardless of which operator a terminal in the target area belongs to, it can send an access request to the backpack base station when it detects that the broadcast information contains its own operator's PLMN ID. Based on the received access requests from the target terminals, the backpack base station can establish connections with different terminals of multiple operators within the target area, facilitating communication between terminals of multiple operators within the target area and the core network equipment of their respective operators through the backpack base station. Furthermore, the backpack base station can send different broadcast information sequentially at different times based on quantity information and predetermined rules, thus meeting the network needs of most terminals while alleviating network pressure.

[0088] It is worth noting that, when the backpack-type base station of this application sends broadcast information, in addition to sending multiple broadcast messages containing the PLMN IDs of operators sequentially in time periods through step 102 above, it can also send broadcast messages containing the PLMN IDs of multiple operators simultaneously.

[0089] For example, the type of target operator can be determined based on the operator information of different terminals within the target area. Based on the type of target operator, the corresponding number of PLMN IDs can be determined. This number of PLMN IDs is then carried in the broadcast information and sent.

[0090] It should be noted that the target operator is any one of the multiple operators whose original base stations are damaged and which belong to different terminals in the target area. The backpack-type base station can provide base station services only to the target operator.

[0091] Carrier information includes the frequency bands allocated to carriers for communication. Different carriers use different frequency bands, and each carrier's frequency band includes multiple frequency points. For any given frequency band, a backpack base station can receive radio frequency signals at a specific frequency point within that band. For example, a backpack base station can receive radio frequency signals at a frequency of 810MHz based on a frequency point of 810MHz. When determining the target carrier type based on the carrier information of different terminals within the target area, the backpack base station can receive radio frequency signals at corresponding frequencies based on each carrier's frequency points, and determine the target carrier type based on the received radio frequency signals.

[0092] In some examples, if a particular operator fails to receive radio frequency signals at any of its frequency points, it is assumed that the operator's existing base stations within the target area are damaged and unusable, thus identifying that operator as the target operator. Conversely, if a particular operator can receive radio frequency signals at a specific frequency point, it is assumed that the operator's existing base stations within the target area are undamaged and usable, thus determining that the operator is not the target operator.

[0093] For example, the first operator uses frequency bands for communication, including band 1 and band 2. Band 1 includes frequency points 1 and 2, and band 2 includes frequency points 3 and 4. If the backpack base station fails to receive radio frequency signals at any of the first operator's frequency points 1, 2, 3, and 4, then the first operator's original base station is considered damaged, and the first operator can be identified as the target operator. Conversely, if the backpack base station can receive radio frequency signals at any of the first operator's frequency points 1, 2, 3, and 4, then the first operator's original base station is considered undamaged, and the first operator will not be identified as the target operator.

[0094] In other examples, if the signal power of the radio frequency (RF) signals received at various frequencies from a particular operator is too low, the RF signal may be generated by noise. Therefore, to reduce false positives caused by noise, the backpack base station, after receiving the RF signal at a specific frequency from a particular operator, can also acquire the signal power of that RF signal. Only when the acquired RF signal power is greater than a preset threshold is it considered that the original base station of that operator in the target area is not damaged, thus determining that the operator is not the target operator. Conversely, when the acquired RF signal power is less than or equal to the preset threshold, it is considered that the original base station of that operator in the target area is damaged, and the operator is identified as the target operator. This reduces the probability of missing some target operators due to false positives. The preset threshold can be the minimum power value obtained from the RF signals transmitted and received by the original base station.

[0095] After identifying the target operator type, the backpack base station can determine the corresponding number of PLMN IDs based on that operator type. It's understood that there's a one-to-one correspondence between the target operator type and the corresponding number of PLMN IDs. In other words, if n target operators are identified, the corresponding number of PLMN IDs is n, where n is a positive integer. The backpack base station can then carry the PLMN IDs corresponding to the target operators in its broadcast information.

[0096] When n=1, the target operator is any one of the first, second, and third operators, and the corresponding PLMN ID count is 1. Assuming the first operator is the target operator, its PLMN ID can be included in the broadcast message. When n=2, the target operator is any two of the first, second, and third operators, and the corresponding PLMN ID count is 2. Assuming the first and third operators are the target operators, both their PLMN IDs can be included in the broadcast message. When n=3, all three operators are target operators, resulting in 3 PLMN IDs. All three PLMN IDs can be included in the broadcast message, meaning the PLMN IDs of the first, second, and third operators can be included simultaneously.

[0097] In this embodiment, the backpack base station can carry the corresponding number of PLMNIDs determined based on the type of target operator in the broadcast information and send them. In this way, the terminals of all target operators in the target area can simultaneously listen to the broadcast information sent by the backpack base station, which facilitates the simultaneous communication of all target operator terminals in the target area through the backpack base station.

[0098] This application also provides a connection establishment device for a backpack-type base station, which communicates with the core network equipment of multiple operators. Figure 3 This is a schematic diagram of the cell establishment device provided in the embodiments of this application, as shown below. Figure 3 As shown, the cell establishment apparatus provided in this application embodiment includes: an acquisition module 301, a sending module 302, a receiving module 303, and a response module 304.

[0099] The acquisition module 301 is used to acquire the number of terminals of each operator in the target area, which is the signal coverage area of ​​the backpack base station.

[0100] The sending module 302 is used to send broadcast information based on quantity information and predetermined rules. The broadcast information contains at least the Public Land Mobile Network IDs (PLMN IDs) of multiple operators. The PLMN IDs of these multiple operators are determined according to the operator information of different terminals in the target area.

[0101] The receiving module 303 is used to receive the access request sent by the target terminal. The access request is sent by the target terminal after it determines that the broadcast information it has listened to contains the PLMN ID of its own operator.

[0102] The response module 304 is used to send an access response to the target terminal to establish a communication connection with the target terminal.

[0103] In some embodiments, the sending module 302 is specifically used for:

[0104] The terminals are sorted by operator according to their quantity information from largest to smallest. Based on the operator sorting, a broadcast message carrying the PLMN ID of the operator sorted by i is sent in the i-th time period, and a broadcast message carrying the PLMN ID of the operator sorted by i+1 is sent in the (i+1)-th time period; where i is an integer greater than 0, and the i-th time period is earlier than the (i+1)-th time period.

[0105] In some embodiments, the duration of the i-th time period is greater than the duration of the (i+1)-th time period.

[0106] In some embodiments, the response module 304 is further configured to:

[0107] Determine the number of terminals currently connected to the backpack-type base station. If the number of terminals currently connected to the backpack-type base station is less than a first threshold, send an access response to the target terminal.

[0108] In some embodiments, the response module 304 is further configured to:

[0109] The number of terminals belonging to the target operator currently connected to the backpack base station is determined. The target operator is the operator to which the target terminal belongs. If the number of terminals belonging to the target operator currently connected to the backpack base station is less than a second threshold, an access response is sent to the target terminal. The second threshold is the number of terminals belonging to the target operator that are allowed to connect to the backpack base station.

[0110] The connection establishment apparatus for a backpack-type base station provided in this application embodiment includes broadcast information from the backpack-type base station containing PLMN IDs of multiple operators. These PLMN IDs are determined based on the operator information of different terminals within the target area. Therefore, regardless of which operator a terminal in the target area belongs to, it can send an access request to the backpack-type base station when it determines that the broadcast information it has received contains the PLMN ID of its own operator. Based on the received access requests from the target terminals, the backpack-type base station can establish connections with different terminals of multiple operators within the target area, thereby facilitating communication between terminals of multiple operators within the target area and the core network equipment of the corresponding operators through the backpack-type base station. Furthermore, the backpack-type base station can send different broadcast information sequentially in time periods based on quantity information and predetermined rules, which can meet the network needs of most terminals and alleviate network pressure.
