Detailed Description
First, an application scenario of the present disclosure will be explained. In the 5G network construction process, in order to save the network construction cost, some operators use a network co-construction and sharing mode to construct the 5G network. For example, the chinese telecom and the chinese unicom will share the co-construction in the 3.5GHz band, and it is determined that an NSA (Non-Stand Alone networking) deployment scheme is adopted, the chinese telecom will use its 1.8GHz LTE (Long Term Evolution ) FDD (Frequency Division duplex) as a MN (Master Node) of dual connection, the chinese unicom will use its 2.1GHz LTE FDD as a MN of dual connection, and the 5G NR (New Radio, new wireless) TDD (Time Division duplex) of the 3.5GHz band will be used as an SN (Slave Node, secondary Node) of dual connection.
To implement the co-establishment sharing between the two operators, the resources of the 5G cell that the two operators share need to be reasonably allocated, so that the terminal using the two operator networks can fairly and efficiently access the 5G network, otherwise, the co-establishment sharing cannot be maintained, which results in a great deal of resource waste.
However, in the related art, there is no technical scheme for performing dual connectivity simultaneously with LTE FDD cells of frequency points of different frequency bands of two operators in a 5G NR cell of the same frequency point, so there is no technical scheme and operation experience that can be referred to at present. The inventor finds in a research process that after receiving an access request message of a target terminal sent by an LTE base station, an NR base station may first obtain a load value of the NR base station, and if it is determined according to the load value that a current load of the NR base station is low, for example, close to an empty load, the NR base station determines to access the target terminal; if the current load of the NR base station is determined to be higher according to the load value, whether the target terminal is accessed can be determined according to a plurality of parameters carried in the access request information. In this way, resources of the NR base stations can be allocated reasonably, so that a terminal using the two operator networks can access the 5G network fairly and efficiently.
In order to solve the above problem, the present disclosure provides a method, an apparatus, a storage medium, and a network device for network access. After the first network equipment receives an access request message sent by the second network equipment, whether a target terminal is accessed is determined by acquiring a load value of the first network equipment and according to the access request message and the load value, and if the target terminal is determined to be accessed, an access confirmation message is sent to the second network equipment. In this way, the first network device can determine whether to access the target terminal according to the access request message and the load condition, so that the resources of the first network device can be reasonably distributed, and the target terminal can be fairly and efficiently accessed to the first network device.
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
In the description that follows, the terms "first," "second," and the like are used for descriptive purposes only and are not intended to indicate or imply relative importance nor order to be construed.
Fig. 1 is a flowchart of a method for network access provided by an embodiment of the present disclosure, where the method is applied to a first network device, and the first network device may be an NR base station. As shown in fig. 1, the method may include:
s101, receiving an access request message sent by second network equipment.
Wherein the second network device may be an LTE base station; the access request message is used to request the first network device to access the target terminal, and may include a terminal identifier of the target terminal, a target service rate required by the service connection requested to be established by the target terminal, an operator identifier of a target operator to which the second network device belongs, and a service connection identifier corresponding to the service connection requested to be established by the target terminal.
In this step, after receiving the service connection request sent by the target terminal, the second network device may first determine whether the target terminal supports 5G dual connectivity, and if it is determined that the target terminal supports 5G dual connectivity, may send an access request message to the first network device according to the service connection request sent by the target terminal, so as to request the first network device to access the target terminal.
S102, acquiring a load value of the first network equipment.
The load value may be a load value at the current time, or a load value of a preset time window after the current time.
In this step, after receiving the access request message sent by the second network device, the first network device may obtain a load value of the first network device, where the load value may be a utilization rate of a physical resource block or a utilization rate of a transport layer packet resource, or a utilization rate of a hardware resource, such as a utilization rate of a CPU, a memory, or the like, or a utilization rate of an average cell capacity, which is not limited in this disclosure. In addition, since the utilization rate of the physical resource block, the utilization rate of the transport layer packet resource, the utilization rate of the hardware resource, and the utilization rate of the average cell capacity at the same time or in the same time period may be different, for example, the utilization rate of the current physical resource block is 40%, the utilization rate of the current transport layer packet resource is 35%, the utilization rate of the current hardware resource is 45%, and the utilization rate of the average cell capacity is 40%, and any one of them may not be accurate enough as the load value, the average value of the utilization rate of the current physical resource block, the utilization rate of the current transport layer packet resource, the utilization rate of the current hardware resource, and the utilization rate of the average cell capacity may be obtained, and the average value is used as the load value of the first network device.
S103, determining whether to access the target terminal according to the access request message and the load value.
In this step, after obtaining the load value of the first network device, the load condition of the first network device may be determined according to the load value, for example, if the load value is low, for example, the load value is 5%, that is, when the load value is close to an empty load, the access target terminal may be directly determined; if the load value is high, for example, the load value is 99%, that is, the load value is close to full load, the access rejection of the target terminal can be directly determined; if the load value is an intermediate value, for example, the load value is 80%, it cannot be determined whether to access the target terminal directly according to the load value. At this time, whether the remaining resources of the first network device can meet the resources required by the service connection requested to be established by the target terminal can be determined according to the access request message, and if the remaining resources of the first network device can meet the requirements of the service connection, the target terminal can be accessed; and if the residual resources of the first network equipment cannot meet the requirement of the service connection, determining to refuse to access the target terminal.
And S104, if the access target terminal is determined, sending an access confirmation message to the second network equipment.
The access confirmation message may include a device identifier of the first network device, random access resource configuration information allocated to the target terminal by the first network device, and an address of the first network device.
In this step, if the first network device determines to access the target terminal according to the access request message and the load value, an access confirmation message may be sent to the second network device, so that the second network device may send the resource configuration information to the target terminal according to the access confirmation message. After receiving the resource configuration information sent by the second network device, the target terminal may send an access request to the first network device according to the resource configuration information to request to access the first network device.
It should be noted that, if the first network device determines to reject to access the target terminal according to the access request message and the load value, the first network device may send an access rejection message to the second network device.
By adopting the method, after the first network equipment receives the access request message sent by the second network equipment, whether the target terminal is accessed is determined by acquiring the load value of the first network equipment and according to the access request message and the load value, and if the target terminal is determined to be accessed, the access confirmation message is sent to the second network equipment. In this way, the first network device can determine whether to access the target terminal according to the access request message and the load condition, so that the resources of the first network device can be reasonably distributed, and the target terminal can be fairly and efficiently accessed to the first network device.
Fig. 2 is a flowchart of a second network access method provided by an embodiment of the present disclosure, and the method is applied to a second network device, which may be an LTE base station. As shown in fig. 2, the method may include:
s201, receiving a service connection request sent by a target terminal.
The service connection request may include a terminal identifier of the target terminal and a target service rate required by the service connection requested to be established by the target terminal.
S202, according to the service connection request, sending an access request message to the first network equipment.
The access request message is used to request the first network device to access the target terminal, and may include a terminal identifier of the target terminal, a target service rate required by the service connection requested to be established by the target terminal, an operator identifier of a target operator to which the second network device belongs, and a service connection identifier corresponding to the service connection requested to be established by the target terminal.
In this step, after receiving the service connection request sent by the target terminal, the second network device may first determine whether the target terminal supports 5G dual connectivity, and if it is determined that the target terminal supports 5G dual connectivity, may send an access request message to the first network device according to the service connection request sent by the target terminal, so as to request the first network device to access the target terminal.
S203, receiving the access confirmation message sent by the first network device.
The access confirmation message may include a device identifier of the first network device, random access resource configuration information allocated to the target terminal by the first network device, and an address of the first network device.
In this step, after receiving the access request message sent by the second network device, the first network device may obtain a load value of the first network device, and determine whether to access the target terminal according to the access request message and the load value. If the first network device determines to access the target terminal, an access confirmation message may be sent to the second network device; if the first network device determines to reject the access to the target terminal, a reject access message may be sent to the second network device.
And S204, sending resource configuration information to the target terminal according to the access confirmation message.
The resource configuration information may include a device identifier of the first network device, and random access resource configuration information allocated to the target terminal by the first network device, and the random access resource configuration information may include a beam identifier and a random access request preamble sequence identifier used when the random access request is transmitted by the target terminal and allocated by the first network device.
In this step, after the second network device receives the access confirmation message sent by the first network device, the second network device may send the resource configuration information to the target terminal according to the access confirmation message. After receiving the resource configuration information sent by the second network device, the target terminal may send an access request to the first network device according to the resource configuration information to request to access the first network device.
By adopting the method, after the second network device receives the service connection request sent by the target terminal, the second network device can send the access request message to the first network device according to the service connection request, and after the first network device confirms to access the target terminal, the first network device receives the access confirmation message sent by the first network device and sends the resource configuration information to the target terminal according to the access confirmation message, so that the target terminal can access the first network device according to the resource configuration information. In this way, the first network device may determine whether to access the target terminal according to the access request message and the load condition sent by the second network device, so that resources of the first network device may be reasonably allocated, and the target terminal may fairly and efficiently access the first network device.
Fig. 3 is a flowchart of a third method for network access provided by an embodiment of the present disclosure. As shown in fig. 3, the method includes:
s301, the second network device receives a service connection request sent by the target terminal.
The service connection request may include a terminal identifier of the target terminal and a target service rate required by the service connection requested to be established by the target terminal.
S302, the second network device sends an access request message to the first network device according to the service connection request.
The access request message may include a terminal identifier of the target terminal, a target service rate required by the service connection requested to be established by the target terminal, an operator identifier of a target operator to which the second network device belongs, and a service connection identifier corresponding to the service connection requested to be established by the target terminal.
It should be noted that, after the second network device receives the service connection request sent by the target terminal and establishes a connection between the target terminal and the core network device, according to the terminal identifier in the service connection request sent by the target terminal, the second network device may obtain an operator identifier of a target operator to which the second network device belongs and an address for communication between the target terminal and a network element of the core network, that is, a request address.
In this step, after receiving the service connection request sent by the target terminal, the second network device may determine whether the target terminal supports 5G dual connectivity, and if it is determined that the target terminal supports 5G dual connectivity, the second network device may send an access request message to the first network device to request the first network device to access the target terminal.
S303, the first network device receives an access request message sent by the second network device.
S304, the first network device obtains the load value of the first network device.
S305, the first network device determines whether to access the target terminal according to the access request message and the load value.
In this step, after obtaining the load value of the first network device, the first network device may first determine whether the load value is greater than or equal to a first preset load threshold. If the load value is smaller than a first preset load threshold value, the current load of the first network equipment is low, and an access target terminal is determined; if the load value is greater than or equal to the first preset load threshold and less than the second preset load threshold, the first network device may determine whether to access the target terminal according to the target service rate.
The first preset load threshold and the second preset load threshold may be preset load thresholds, for example, the first preset load threshold may be set to 20%,10% or 5%, and the second preset load threshold may be set to 70%,65% or 60%, which is not limited by the present disclosure. In addition, different preset load thresholds may be set according to the load type, for example, if the first network device determines the load value according to the utilization rate of the physical resource block, the first preset load threshold may be set to 20%, and the second preset load threshold may be set to 70%; if the first network device determines the load value according to the average cell capacity occupancy, the first preset load threshold may be set to 5%, and the second preset load threshold may be set to 60%.
It should be noted that, if the first network device determines that the load value is greater than the second preset load threshold, it may determine to deny access to the target terminal.
Further, when determining whether to access the target terminal according to the target service rate, the first network device may first obtain a preset rate threshold corresponding to the target operator according to an operator identifier of the target operator, which is sent by the second network device. The preset rate threshold may be determined by a contract made by a co-established and shared operator, for example, the same preset rate threshold may be set for two co-established and shared operators, or the preset rate threshold allocated to the operator may be determined according to an amount paid by the operator, for example, if the amount paid by the operator a is higher, the preset rate threshold of the operator may be dynamically set according to time, for example, from 9 to 12 points, the resource allocated to the operator a is 50% of the total resource, from 20 to 23 points, the resource allocated to the operator a is 80% of the total resource, and then the resource occupancy rate is converted into the corresponding rate.
After obtaining the preset rate threshold corresponding to the target operator, the first network device may determine, from the service connections currently established with the first network device, a plurality of target service connections belonging to the target operator, for example, if 20 service connections currently established with the first network device are connected, 8 target service connections belonging to the target operator may be determined from the 20 service connections. Thereafter, the first network device may obtain a sum of service rates corresponding to the target service connections to determine a service rate used by the target operator, and may obtain a difference between the sum and a preset rate threshold, where the difference may be calculated, for example, by the following formula:
Figure BDA0002351164830000131
wherein D is diff Difference between sum of service rates corresponding to a plurality of target service connections and a predetermined rate threshold, D threshold To preset a rate threshold, D i Is the traffic rate of terminal i.
After obtaining the difference between the sum of the service rates corresponding to the multiple target service connections and the preset rate threshold, the first network device may compare the target service rate with the difference, and determine whether the target service rate is less than the difference. If the target service rate is less than the difference value, determining to access the target terminal; and if the target service rate is greater than or equal to the difference value, determining to refuse to access the target terminal.
S306, if the first network device determines to access the target terminal, the first network device sends an access confirmation message to the second network device.
The access confirmation message may include a device identifier of the first network device, random access resource configuration information allocated to the target terminal by the first network device, and an address of the first network device.
In this step, if the first network device determines to access the target terminal, an access confirmation message may be sent to the second network device; if the first network device determines to reject access to the target terminal, a reject access message may be sent to the second network device.
