Description

Network configuration method and device

Technical Field

The present invention relates to the field of network communication technologies, and in particular, to a network configuration method and apparatus.

Background

In the construction of the 5G network, 5G may be used as a macro coverage independent network, or a hot spot coverage may be performed in a 5G micro cell. No matter which networking mode is adopted, the wireless resource utilization rate can be improved, the system switching time delay is reduced, and the user performance and the system performance are improved through a double-connection technology between an LTE (Long Term Evolution) system and a 5G system.

In the process of realizing EN-DC (E-UTRA-NR Dual Connectivity, 4G/5G Dual Connectivity), NR (New Radio, Wireless New air interface) frequency points are configured in the following mode:

when a User Equipment (UE) establishes a network, a base station acquires an attribute of the UE, determines whether the UE meets a 3GPP (3rd Generation Partnership Project) Release 15 standard, and acquires a switch of a base station EN-DC. When the UE reaches the standard of R15 and supports EN-DC, the UE is configured with supported NR frequency point and B1 measurement event for adding the secondary node EN-gNB. When a B1 measurement event for adding the auxiliary node en-gNB reports a cell related to the neighboring cell relationship, the base station configures the cell with the added en-gNB and configures a B2 measurement event for deleting the en-gNB, so as to meet the requirements of the UE.

However, the above-mentioned way of configuring the NR frequency point has the following disadvantages:

1. wasting network resources. When configuring the en-gbb, the en-gbb is configured only according to whether the capability of the UE meets the standard of R15, but does not consider the actual situation, and for a user with only small packet data, configuring the en-gbb wastes a large amount of Channel resources such as PDSCH (Physical Downlink Shared Channel), PDCCH (Physical Downlink control Channel), and the like.

2. The time delay of the configured en-gNB is larger. In the above NR frequency point configuration manner, when configuring the en-gNB, the B1 measurement event needs to be configured first, and then the en-gNB can be configured only after the B1 measurement event is reported to the designated cell, which is likely to cause a certain time delay.

3. The delay perception and service perception of a Voice over Long-Term Evolution (lte) user or a real-time streaming media user cannot be guaranteed.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

In a specific implementation, the LTE/5G dual connectivity mode includes: 3/3a/3x, 4/4a, and 7/7a/7 x. The interconnection of an LTE.5G system can be realized through an EN-DC double-connection technology, so that the utilization rate of wireless resources of the whole mobile network system is improved, the time delay of system switching is reduced, and the performance of a user and the system is improved.

In the LTE/5G dual connectivity mode 3/3a/3x scenario, both LTE and 5G base stations are connected on the LTE core network, the LTE eNB always acts as a master eNB (i.e., MeNB), the 5G gbb acts as a slave eNB (i.e., SeNB), and the LTE eNB and 5G gbb are interconnected through an Xx interface connection. Control plane up S1-C terminates at LTE eNB, and control plane information between LTE and 5G interacts over the Xx-C interface. The user plane has different user plane protocol architectures under different dual connectivity modes. The data plane radio bearer may be independently served by the MeNB or the SeNB, or may be simultaneously served by the MeNB and the SeNB. MCG bearers when served only by MeNB (MCG is the group of serving cells controlled by MeNB), SCG bearers when served only by SeNB (SCG is the group of serving cells controlled by SeNB), split bearers and SCG split bearers when served by MeNB or SeNB at mode 3a, as in mode 3 and mode 3x in fig. 3.

Under the condition of the dual connectivity mode 3, a separate bearer is established on the MeNB, that is, the LTE eNB, and through the separate bearer, a packet Data Convergence protocol packet pdcp (packet Data Convergence protocol) may be forwarded to a radio link control layer RLC (radio Resource control) of the gNB via the Xx interface, or may be directly sent to the terminal through the local RLC. In the mode 3a, bearers are respectively established on the MeNB and the SeNB, and data is separated on the core network side, which does not affect a data Convergence protocol layer dcp (data Convergence protocol) of the MeNB and the SGNB. In the mode 3x, the split bearer is established on the SGNB, i.e., the 5G gbb side, and the 5G gbb may forward PDCP packets to the LTE eNB through the Xx interface, or may directly transmit the PDCP packets through the local NR RLC.

With the deployment of the 5G core network, one possible LTE and 5G convergence method is to connect an evolved LTE (LTE) eNB to the 5G core network. In this scenario, 3GPP defines two different LTE/5G dual connectivity modes depending on whether the MeNB is an LTE eNB or a 5G gbb. One pattern is 5G gbb as MeNB, referred to as pattern 4/4 a. The other mode is with LTE eNB as MeNB, referred to as mode 7/7a/7 x. The dual connectivity mode 7/7a/7x and the dual connectivity mode 3/3a/3x are similar in protocol architecture, with the difference being whether the core network is a 5G core network or an LTE core network.

Based on the above dual connectivity mode 3, referring to fig. 1, a flowchart of steps of an embodiment of a network configuration method of the present invention is shown. The method specifically comprises the following steps:

step 101, a main base station receives an establishment request initiated by a user terminal;

in practice, after the UE accesses LTE, the LTE eNB main base station may determine whether to add an auxiliary base station to the UE according to UE capabilities reported by the UE, such as whether the UE supports LTE/5G dual connectivity, whether there are 5G cells supporting LTE/5G dual connectivity in a neighbor list, and an Xx link state of the 5G cells, that is, a second 5G base station sgnb (secondary gbb).

In a specific implementation, a path between the LTE eNB main base station (i.e., MeNB, described below) and the user terminal includes a user plane data path and a control plane data path, and a path between the 5G gbb secondary base station (i.e., SeNB, described below) and the user terminal includes a user plane data path. The core network and the MeNB may establish a user plane data path and a control plane data path, and the SeNB and the core network may or may not establish a user plane data path with the core network.

In the embodiment of the invention, a user can initiate a networking establishment request to the MeNB through the user terminal so that the user terminal can access the LTE.

It should be noted that, in the embodiment of the present invention, the MeNB receives the establishment request of the user terminal, and may receive an initial context establishment request initiated by the user terminal, that is, the user terminal does not access the LTE before, which is the first access. The MeNB may also receive an evolved radio access bearer ERAB establishment request initiated by the core network, that is, the user terminal has previously accessed LTE and is attached to the network.

Step 102, acquiring bearer establishment information carried in an establishment request;

in the embodiment of the invention, in the process of accessing the LTE, the initiated establishment request carries information for establishing the target bearer, and the MeNB acquires the bearer establishment information carried in the establishment request and uses the core network for establishing the target bearer for the user terminal.

In a specific implementation, the MeNB receives an establishment request initiated by the user terminal, then obtains bearer establishment information carried in the establishment request, and then establishes a target bearer for the user terminal through the core network.

Step 103, acquiring a bearer service type of a target bearer;

in a specific implementation, after the user terminal establishes a connection with the MeNB and attaches to the network, the core network may establish a default bearer for the user terminal, and when the user terminal needs to initiate another service, such as a real-time voice call, the core network may establish a dedicated bearer corresponding to the QoS for the user terminal according to the service initiated by the user terminal.

In the embodiment of the invention, the core network establishes the target bearer for the user terminal, and the MeNB can acquire the bearer service type of the target bearer. The bearer service type includes a first service bearer and a second service bearer, where the first service bearer is a GBR bearer (i.e., a dedicated bearer), and the second service bearer is a Non-GBR bearer (i.e., a default bearer).

It should be noted that, in the embodiment of the present invention, the first traffic bearer includes a GBR bearer of the target traffic and a GBR bearer of the preset traffic. The Class of QCI (qos Class identifier) may be selected for the GBR bearer of the target traffic, such as QCI1, or QCI2, or QCI3, and QCI 4.

And 104, configuring the auxiliary base station according to the type of the bearer service.

In the embodiment of the present invention, after acquiring the bearer service type of the target bearer established by the core network for the user terminal, the MeNB may determine whether to configure the SGNB for the user terminal according to different bearer service types, as shown in fig. 2, a data flow diagram after configuring the SGNB for the user terminal under LTE/5G dual connectivity.

In a preferred embodiment of the present invention, step 104 may comprise the following sub-steps:

in a specific implementation, after acquiring the bearer service type of the target bearer, the MeNB detects that the bearer service type belongs to the first service bearer, and when the first service bearer is the GBR bearer of the target service, performs substeps S11-S13, and when the first service bearer is the GBR bearer of the preset service, performs substeps 14-S15.

Substep S11, obtaining QoS information of all first service bearers connected between the user terminal and the main base station;

in a specific implementation, after the user terminal accesses the LTE and attaches to the network, the MeNB may obtain a bearer service type established by the core network for the user terminal. When the core network establishes a first service bearer according to the requirement of the user terminal when accessing the LTE, and the first service bearer is a GBR bearer of the target service, the MeNB may obtain QoS information of all first service bearers connected between the user terminal and the base station. The QoS information is the first guaranteed bit rate and value of all the first traffic bearers, including the guaranteed bit rate of the GBR bearer of the target traffic and the guaranteed bit rates of the GBR bearers of other traffic.

Substep S12, determining whether the first guaranteed bit rate and the value satisfy a first preset threshold;

in this embodiment of the present invention, after acquiring the first guaranteed bit rates and values of all the first traffic bearers, the MeNB may compare the sum value with a first preset threshold, and determine whether the sum value meets the first preset threshold.

In a specific implementation, when the sum is greater than or equal to a first preset threshold, the MeNB may select a target 5G neighboring cell to initiate an SGNB adding procedure for the user terminal, configure an SGNB and a first measurement Event for the user terminal, where the first measurement Event is Event B2, and is an Event for reporting and deleting the SGNB, where the target 5G neighboring cell is a 5G cell that supports LTE/5G dual connectivity and is connected in an Xx link state.

When the MeNB detects that the first guaranteed bit rate sum is smaller than the first preset threshold, the MeNB may periodically or real-timely monitor the actual transmission rate of the ue through the data link layer L2, obtain the actual transmission rate of the ue, and perform sub-step S13.

Step S13, judging whether the actual transmission rate meets a second preset threshold;

in a specific implementation, the MeNB may monitor, by using the L2, the actual transmission rate of the user terminal at regular time or in real time, compare the actual transmission rate with a second preset threshold, select a target 5G neighboring cell to initiate an SGNB adding procedure for the user terminal when the actual transmission rate of the user terminal is greater than or equal to the second preset threshold, and configure the SGNB and the first measurement event for the user terminal.

And when the actual transmission rate of the user terminal is less than the second preset threshold, the MeNB continuously monitors the actual transmission rate of the user terminal through the data link layer.

Substep S14, obtaining the actual transmission rate of the user terminal;

in a specific implementation, after the user terminal accesses the LTE and attaches to the network, the MeNB may obtain a bearer service type established by the core network for the user terminal. When the core network establishes the first service bearer according to the requirement of the user terminal when accessing the LTE, and the first service bearer is a GBR bearer of a preset service, that is, the user terminal does not need to establish the GBR bearer of the target service when accessing the LTE. The MeNB may monitor the actual transmission rate of the user terminal in real time during the attachment of the user terminal to the network and then perform sub-step S15.

A substep S15, determining whether the actual transmission rate satisfies a second preset threshold;

In another preferred embodiment of the present invention, step 104 may include the following sub-steps:

substep S21, obtaining the actual transmission rate of the user terminal;

in the embodiment of the present invention, after acquiring the bearer service type of the target bearer, and when detecting that the bearer service type belongs to the second service bearer, the MeNB may monitor the actual transmission rate of the user terminal at regular time or in real time through L2, and acquire the actual transmission rate of the user terminal.

A substep S22, determining whether the actual transmission rate satisfies a second preset threshold;

in a specific implementation, after obtaining an actual transmission rate of the user terminal through L2, the MeNB compares the actual transmission rate with a second preset threshold, and when the actual transmission rate of the user terminal is greater than or equal to the second preset threshold, selects a target 5G neighboring cell for the user terminal to initiate an SGNB adding procedure, and configures an SGNB and a first measurement event for the user terminal.

Compared with the above-mentioned embodiments of sub-step S11-sub-step S15, the difference between the embodiment of sub-step S21-sub-step S22 and the above-mentioned embodiments of sub-step S11-sub-step S15 is that, in this embodiment, when the ue accesses to LTE, the core network establishes a default second service bearer for the ue according to QoS requirements of the ue, when the MeNB determines whether to configure an SGNB for the ue, the core network monitors an actual transmission rate of the ue only through a data link layer L2 of the MeNB, after acquiring the actual transmission rate of the ue, then determines the actual transmission rate, and when the actual transmission rate satisfies a second preset threshold, configures the SGNB and a first measurement event for the ue.

In a preferred embodiment of the present invention, the method may further include the following steps:

and the MeNB receives the first measurement event, deletes the SGNB configured for the user terminal, and then configures a second measurement event for the user terminal.

In a specific implementation, when the user terminal reports a first measurement Event for deleting the SGNB, which indicates that the NR carrier signal is weak at this time, that is, the radio propagation capability of the 5G NR frequency band is insufficient, the MeNB is notified to delete the SGNB, and after receiving the first measurement Event, the MeNB deletes the SGNB and configures a second measurement Event for the user terminal, where the second measurement Event is Event B1 and configures the SGNB for reporting. When the second measurement event configured with the SGNB is reported, it indicates that the NR carrier signal is good, and the SGNB may be configured for the user terminal.

In the embodiment of the invention, the MeNB configures the SGNB for the user terminal, configures the first measurement event, deletes the SGNB when the NR carrier signal is weaker, and configures the second measurement event, so that the SGNB can be configured for the user terminal according to the strength of the NR carrier signal, thereby avoiding the waste of resources and providing the utilization rate of the resources.

In the embodiment of the present invention, the method is applied to LTE/5G dual connectivity, and in a process that a user equipment is attached to a network, an MeNB (i.e. a 4G primary base station) receives an establishment request initiated by the user equipment, where the establishment request includes an initial context establishment request initiated by the user equipment or an evolved radio access bearer ERAB establishment request initiated by the user equipment, then obtains information carried in the establishment request for establishing a target bearer and obtains a bearer service type of the target bearer, then configures an SGNB (a 5G secondary base station) for the MeNB according to different bearer service types, specifically, determines whether the MeNB configures the SGNB according to different bearer service types, by using quality of service (QoS) information or an actual transmission rate detected by a base station data link layer L2, so that when the user equipment is initially accessed and needs a high QoS requirement, the MeNB configures the SGNB, the transmission rate of the user terminal is rapidly improved, the data delay is reduced, and the user perception is improved. In addition, in the access process of the user terminal, when the actual transmission rate of the user terminal reaches a certain condition, the SGNB is configured for the MeNB, the SGNB is configured according to the actual requirement of the user terminal, the problem of resource waste caused by advanced configuration is avoided, the saved resources can be configured for other user terminals, and the utilization rate of the resources is improved.

Referring to fig. 3, a flowchart of steps of another embodiment of a network configuration method of the present invention is shown, which specifically includes the following steps:

Step 302, acquiring bearer establishment information carried in an establishment request;

Step 303, acquiring a bearer service type of a target bearer;

after the ERAB is successfully established, the MeNB may obtain the bearer service type of the target bearer. The bearer service type comprises a first service bearer and a second service bearer, wherein the first service bearer is a GBR bearer, and the second service bearer is a Non-GBR bearer.

Step 304, configuring an auxiliary base station according to the type of the bearer service;

in the embodiment of the present invention, after acquiring the bearer service type of the target bearer established by the core network for the user terminal, the MeNB may determine whether to configure the secondary base station SGNB for the user terminal according to the bearer service type.

In a preferred embodiment of the present invention, step 304 may comprise the following sub-steps:

substep S31, obtaining the guaranteed bit rate and value of all first service bearers connected between the user terminal and the main base station;

in a specific implementation, after the ERAB is successfully established, the MeNB may obtain a bearer service type established by the core network for the ue. When the core network establishes the first service bearer according to the requirement of the user terminal during the ERAB establishment and the first service bearer is the GBR bearer of the target service, the MeNB may obtain the guaranteed bit rate and value of all the first service bearers connected between the user terminal and the base station.

And a sub-step S32 of determining whether the guaranteed bit rate sum value satisfies a first predetermined threshold.

In a specific implementation, after acquiring the guaranteed bit rates and values of all the first traffic bearers, the MeNB may compare the sum with a first preset threshold, and determine whether the sum satisfies the first preset threshold. When the sum is greater than or equal to the first preset threshold, the MeNB may select a target 5G neighbor cell for the user terminal to initiate an SGNB addition procedure, and configure the SGNB and the first measurement event for the user terminal.

Step 305, receiving a deletion request initiated by a user terminal;

the MeNB configures the SGNB for the user terminal, and after a user initiates a request for deleting the ERAB according to actual requirements, the MeNB can receive the ERAB deleting request initiated by the user terminal.

Step 306, acquiring the bearer deletion information carried in the deletion request;

in a specific implementation, the MeNB receives a deletion request initiated by the user terminal, then obtains bearer deletion information carried in the deletion request, and then deletes a target bearer through the core network.

Step 307, acquiring a bearer service type of the target bearer;

in the embodiment of the present invention, the MeNB may obtain the bearer service type of the target bearer while the core network deletes the target bearer. The bearer service type comprises a first service bearer and a second service bearer.

And 308, judging whether to delete the auxiliary base station according to the type of the bearer service.

In the embodiment of the present invention, after the MeNB obtains the bearer service type of the target bearer deleted by the core network, it may be determined whether to delete the secondary base station SGNB configured for the user terminal according to the deleted bearer service type of the target bearer.

In a preferred embodiment of the present invention, step 308 may comprise the following sub-steps:

and a substep S51 of determining whether the bearer service type of the deleted target bearer is the GBR bearer of the target service, if so, executing a substep S52, otherwise, executing a substep S54.

It should be noted that, in the embodiment of the present invention, an example is given in which the user equipment configures the SGNB based on the first guaranteed bit rate satisfying the first preset threshold.

In a specific implementation, after acquiring the bearer service type of the target bearer deleted by the core network, the MeNB may determine the bearer service type, and when the bearer service type is the first service bearer and is a GBR bearer of the target service, perform substep S52; when the bearer traffic type is the first traffic bearer and is a GBR bearer of the preset traffic, the sub-step S54 is performed.

Substep S52, obtaining the guaranteed bit rate and value of all the remaining first service bearers connected between the user terminal and the main base station after deleting the GBR bearer of the target service;

in a specific implementation, when the MeNB detects that the bearer service type of the target bearer deleted by the core network is the first service bearer and is the GBR bearer of the target service, the MeNB may obtain the guaranteed bit rates and values of all remaining first service bearers except the GBR bearer of the target service. Next, sub-step S53 is performed.

And a sub-step S53 of determining whether the guaranteed bit rate sum value satisfies a second predetermined threshold.

After the GBR bearer of the target service is deleted by the core network, the MeNB obtains the guaranteed bit rate and the value of the remaining first service bearer (i.e., the remaining GBR bearer), and then compares the guaranteed bit rate and the value with a second preset threshold to determine whether the guaranteed bit rate and the value satisfy the second preset threshold.

When the sum of the guaranteed bit rates is smaller than the first preset threshold, which indicates that the QoS requirement of the ue is not high at this time, the MeNB may delete the SGNB, and configure a second measurement event for the ue.

When the guaranteed bit rate sum value is greater than or equal to a first preset threshold, the MeNB maintains the SGNB configured for the user terminal.

And a substep S54 of maintaining the SGNB configured for the user terminal.

When the bearer service type of the target bearer deleted by the core network is the first service bearer and is a GBR bearer of a preset service, which indicates that the user terminal still maintains a higher QoS requirement at this time, the SGNB is continuously maintained for the user terminal to meet the requirement of the user.

In the embodiment of the invention, when the request for deleting the ERAB is received, the target bearer can be deleted through the core network, and then whether the SGNB configured for the user terminal is deleted or not is judged according to the bearer service type of the target bearer, so that the waste of resources is avoided.

Step 404, configuring an auxiliary base station according to the type of the bearer service;

In a preferred embodiment of the present invention, step 404 may include the following sub-steps:

substep S61, obtaining the actual transmission rate of the user terminal;

after acquiring the bearer service type of the target bearer established by the core network for the user terminal, the MeNB detects that the bearer service type of the target bearer is the GBR bearer of the preset service, and may monitor the actual transmission rate of the user terminal in real time or at regular time through the data link layer L2.

And a sub-step S62 of determining whether the actual transmission rate satisfies a second predetermined threshold.

Step 405, receiving a deletion request initiated by a user terminal;

after the user initiates a request for deleting the ERAB according to actual requirements, the MeNB may receive the ERAB deletion request initiated by the user terminal.

Step 406, acquiring the bearer deletion information carried in the deletion request;

Step 407, acquiring a bearer service type of the target bearer;

And step 408, judging whether to delete the auxiliary base station according to the type of the bearer service.

In a preferred embodiment of the present invention, step 408 may comprise the following sub-steps:

and a substep S71 of determining whether the bearer service type of the deleted target bearer is the second service bearer, if so, executing a substep S72.

It should be noted that, in the embodiment of the present invention, an example is described by taking an SGNB configured by a user equipment based on that an actual transmission rate satisfies a second preset threshold.

In a specific implementation, after acquiring the bearer service type of the target bearer deleted by the core network, the MeNB may determine the bearer service type, and when it is detected that the bearer service type is the second service bearer, perform substep S72.

And a substep S72 of maintaining the SGNB configured for the user terminal.
