Description

Method and terminal equipment for wireless bearer processing

This application claims the priority of a Chinese patent application filed with the Chinese Patent Office on August 30, 2019, with the application number 201910816489.2, and the invention title is "a method and terminal equipment for wireless bearer processing", the entire content of which is incorporated by reference In this application.

Technical field

This application relates to the field of communication technologies, and in particular to a method and terminal equipment for processing radio bearers.

Background technique

With the development of access network technology, the 3GPP protocol has been continuously improved and improved along with the progress of communication technology. Among them, the 3GPP R15 protocol defines long term evolution (LTE) and new radio (NR). Dual connectivity (DC) architecture. In the initial stage of the application of the DC architecture, most network operators adopted the LTE and NR dual connectivity (E-UTRA-NR Dual Connectivity, EN-DC) architecture in the DC architecture. Using this architecture does not need to update the existing 4th generation mobile communication technology (4G) core network to a 5G core network, but only needs to add a 5G base station on the basis of the existing 4G base station , So as to provide the terminal with a "4G+5G" joint access service, increase the bandwidth of the radio bearer, and achieve the effect of increasing the data transmission rate. In other communication networks (such as wireless local area networks), there are also methods to increase the bandwidth of the wireless bearer, which can also achieve the effect of increasing the data transmission rate.

Take the EN-DC architecture in the DC architecture as an example. In the EN-DC network, the terminal first accesses the network through a 4G base station to establish a radio resource control (RRC) connection. When the 4G base station has a coordinated 5G base station, the 4G base station can reconfigure the specific 4G radio bearer established by the terminal and the 4G base station to add link resources for the 5G network through RRC reconfiguration, and split the original 4G radio bearer into dual links Above, a split bearer is formed. By splitting the bearer, the user's uplink data can be transmitted through 4G and 5G wireless links at the same time, shunted to 4G and 5G cells, and then aggregated in 5G base stations. Downlink data can also be shunted through 5G base stations, passing 4G and 5G The cell is sent to the terminal and converged in the terminal. It can be seen that the split bearer has a larger bandwidth, and the data throughput rate of the split bearer is higher. This wireless bearer with increased bandwidth through the configuration of network-side equipment (such as base stations, wireless routers, etc.) can be called a large-bandwidth wireless bearer.

In the current network architecture, since there is currently no corresponding protocol stipulating how the network side device selects the radio bearer when configuring the large bandwidth radio bearer, when the terminal and the network side device establish multiple radio bearers, the network side device may only One or part of the radio bearers is configured as a large-bandwidth radio bearer, and the large-bandwidth radio bearer configured by the network-side device may not be a radio bearer used to transmit service data. If the network side device configures an established radio bearer as a large-bandwidth radio bearer, and the terminal has a data service request, it may re-establish a new radio bearer service to transmit service data, instead of using the established radio bearer. The high-bandwidth radio bearer is used to transmit service data, as shown in Figure 1, which will cause the large-bandwidth radio bearer to not be effectively used.

Fig. 3 is a schematic diagram of an embodiment of a radio bearer processing method provided by an embodiment of the present application.

As shown in FIG. 3, an embodiment of the radio bearer processing method provided by the embodiment of the present application may include:

301. The terminal device generates a first network interface.

When a data service request is generated in the application processing layer of the terminal device, the data service request will carry the access point name (APN). When the APN carried in the data service request corresponds to the existing radio bearer When the APN is inconsistent, the terminal device will use the APN carried in the data service request to request the network side device to establish a new radio bearer. After the establishment of the new radio bearer is completed, the application processing layer of the terminal device will configure a network interface corresponding to the data service request. The first network interface in this embodiment is a network interface correspondingly generated by the terminal device after the new first radio bearer is established.

302. The terminal device obtains parameter information of each radio bearer in the first radio bearer set.

In this embodiment, the first radio bearer set includes the first radio bearer newly established by the network side device for the terminal device and at least one existing second radio bearer, and the first network interface is the first newly created radio bearer for the terminal device according to the terminal device. The radio bearer is generated accordingly. It should be noted that the at least one existing second radio bearer included in the above-mentioned first radio bearer set is established before the first radio bearer is established, and at least one radio bearer included in the first radio bearer set is when the terminal device accesses the network. When registering, the network side device actively establishes for the terminal device instead of being triggered by the terminal device. The application processing layer of the terminal device actively triggers the establishment of the network side device on demand. The terminal device can actively trigger the network side device to establish more radio bearers according to demand to increase the number of radio bearers in the first radio bearer set, so that the first radio bearer set contains as many high-bandwidth radio bearers as possible. The first network interface can be mapped and bound to the large-bandwidth radio bearer as much as possible, thereby improving the utilization rate of the large-bandwidth radio bearer. The function of the terminal device to obtain the parameter information of each radio bearer in the first radio bearer set is to filter out the large-bandwidth radio bearers matching the service type supported by the first network interface from the first radio bearer set.

303. The terminal device determines the second radio bearer set according to the parameter information of each radio bearer in the first radio bearer set and the first network interface.

In this embodiment, the terminal device can determine the service type supported by each radio bearer, such as a specific service and a general service, according to the parameter information of each radio bearer in the first radio bearer set. Specific services refer to a small part of special services in data services (for example, specific IP services, which require a specific radio bearer to transmit the quintuple information of IP packets). Such specific services can only be based on specific network interfaces and The wireless bearer is used for service data transmission. General business refers to most of the Internet business in the data business, this general business can be based on any network interface and wireless bearer for business data transmission. The second radio bearer set includes radio bearers in the first radio bearer set that match the service type supported by the first network interface.

304. The terminal device determines a target radio bearer according to the parameter information of each radio bearer in the second radio bearer set, where the target radio bearer is a radio bearer in the second radio bearer set whose bandwidth value meets a preset condition.

In this embodiment, after the terminal device determines the second radio bearer set, the terminal device can determine a target radio bearer whose bandwidth value meets a preset condition from the second radio bearer set to perform mapping and binding with the first network interface. The target radio bearer is a large-bandwidth radio bearer, which may be a split bearer configured by a base station for terminal devices in an access network scenario, or a radio bearer whose bandwidth is increased in other common scenarios by other means. Generally, the number of such large-bandwidth radio bearers is small, so the terminal device can also directly determine a radio bearer with the largest bandwidth value from the second radio bearer set as the target radio bearer.

It should be noted that since the first network interface is generated by the terminal device according to the newly created first radio bearer, the service types supported by the first network interface and the first radio bearer must also be the same, that is, the second radio bearer The first radio bearer is also included in the set, so there may be a situation where the target radio bearer is the first radio bearer.

305. The terminal device maps and binds the target radio bearer with the first network interface.

In this embodiment, after the terminal device determines the target radio bearer, the target radio bearer is the optimal radio bearer for the first network interface, and the terminal device maps and binds the target radio bearer to the first network interface. Thus, the service data is transmitted based on the first network interface and the target radio bearer.

In this embodiment, the terminal device can map and bind the first network interface to the target radio bearer when generating the first network interface, so that the data service of the terminal device based on the first network interface can be transmitted through the target radio bearer. Data, so as to make full use of the large-bandwidth characteristics of the target radio bearer, increase the data throughput rate during service data transmission, and improve the network performance and the effective utilization of the large-bandwidth radio bearer.

In a specific embodiment, the terminal device may also connect some network interfaces that have established a mapping binding relationship with a radio bearer with a smaller bandwidth value to the new high-bandwidth radio bearer when a new large-bandwidth radio bearer is established. Re-mapping and binding, so as to make full use of the newly built large-bandwidth radio bearer network resources.

In a specific embodiment, the parameter information of the radio bearer may include: dual connectivity (DC) status information corresponding to the radio bearer, quality of service (QOS) parameters, and quality of service (QOS) class identifiers. Identifier, QCI), Internet protocol address (Internet protocol address, IP), and service flow template (traffic flow template, TFT) and other parameters.

The content of the above-mentioned embodiments will be described in further detail below.

FIG. 4 is a schematic diagram of another embodiment of a method for processing a radio bearer provided by an embodiment of the present application.

As shown in FIG. 4, another embodiment of the radio bearer processing method provided by the embodiment of the present application may include:

401. The terminal device generates a first network interface.

In this embodiment, the content of step 401 is similar to the content of step 301, and reference may be made to the related description in step 301 above, which will not be repeated here.

402. The terminal device obtains parameter information of each radio bearer in the first radio bearer set.

In this embodiment, the parameter information of each radio bearer may include: DC state information, QOS parameters, QCI, IP address, and TFT corresponding to each radio bearer.

403. The terminal device determines, according to at least two of the QCI, IP address, and service flow template TFT corresponding to each radio bearer in the first radio bearer set, what each radio bearer in the first radio bearer set supports. business type.

In this embodiment, QCI is used to indicate indicators such as the service delay and packet loss rate of the radio bearer. When the value of the QCI corresponding to the radio bearer is between 5 and 9, it means that the radio bearer can support general services, otherwise It shows that the radio bearer can only support specific services. The IP address and TFT are used to define the five-tuple information of the IP packet that can be transmitted by the wireless bearer. If there is a TFT in the parameter information corresponding to the radio bearer, it means that the radio bearer can only support specific services. If there is no TFT, it means that it may support general services. Through the combination of parameter information formed by QCI, IP address and TFT, the type of service supported by the radio bearer can be judged.

404. The terminal device determines the service type supported by the first network interface.

In this embodiment, specifically, the terminal device can determine the type of service supported by the first network interface according to the routing information corresponding to the first network interface, and the routing information corresponding to the first network interface corresponds to when the terminal device generates the first network interface. Generated. The terminal device can determine the service type supported by the first network interface by acquiring the routing information. For example, assuming that the routing rules contained in the routing information corresponding to the first network interface are general routing rules, and there is no special identification to limit, and the routing table contained therein has default routes, it can indicate that the first network interface supports general services. Otherwise, it means that the first network interface can only support specific services.

405. The terminal device determines the second radio bearer set according to the service type supported by each radio bearer in the first radio bearer set and the service type supported by the first network interface.

In this implementation, according to whether each radio bearer and the first network interface in the first radio bearer set support general services or specific services at the same time, a radio bearer that matches the service type supported by the first network interface can be determined. The second radio bearer set can be determined.

406. The terminal device determines the target radio bearer according to the DC state information or QOS parameter corresponding to each radio bearer in the second radio bearer set.

In this embodiment, the DC state information corresponding to each radio bearer in the second radio bearer set may indicate whether the radio bearer is a split bearer. When the DC status information corresponding to a radio bearer indicates that the radio bearer is a split bearer, it indicates that the radio bearer is a target radio bearer. The QOS parameter corresponding to each radio bearer in the second radio bearer set may be used as a reference for the bandwidth size of all radio bearers in the second radio bearer set. Specifically, the maximum aggregation bit rate (aggregation maximum bit rate, AMBR) in the QOS parameter corresponding to each radio bearer indicates the maximum rate of the radio bearer under the control of the core network, and the radio bearer indicated by AMBR is under the control of the core network The greater the maximum rate, the greater the bandwidth. In this embodiment, the terminal device can select the radio bearer with the largest bandwidth as the target radio bearer according to the QOS parameters.

407. The terminal device maps and binds the target radio bearer with the first network interface.

In this embodiment, the content of step 407 is similar to the content of the above step 305, and reference may be made to the related description of the above step 305, and the details will not be repeated here.

408. The terminal device sends a radio bearer establishment request to the network side device, and the radio bearer establishment request is used to request the network side device to establish a new third radio bearer for the terminal device.

In this embodiment, the terminal device can actively trigger the network side device to establish a new radio bearer, that is, the third radio bearer, by sending a radio bearer establishment request to the network side device. The purpose of creating a new third radio bearer is to increase the number of radio bearers in the first radio bearer set in the foregoing embodiment, thereby increasing the screening range of target radio bearers, so that the network interface generated by the terminal device has a larger space for radio bearer selection.

409. If the bandwidth value of the third radio bearer is greater than the radio bearer corresponding to the second network interface and matches the service type supported by the second network interface, the terminal device maps and binds the second network interface with the third radio bearer set.

In this embodiment, the second network interface is a network interface generated by the terminal device before the third radio bearer is established. The second network interface is originally mapped and bound with other radio bearers that do not have the characteristics of large bandwidth. When the newly created third radio bearer is greater than the bandwidth value of the radio bearer originally corresponding to the second network interface, and can be combined with the second network If the service types supported by the interface match, the terminal device can re-map and bind the second network interface and the third radio bearer, as shown in FIG. 5. In this way, the original data service based on the second network interface can transmit service data through the newly created third radio bearer, which can increase the data transmission rate and fully utilize the network resources of the newly created third radio bearer.

In this embodiment, the terminal device can actively trigger the establishment of more radio bearers, which increases the selection space for radio bearers. When the terminal device generates a new network interface, it is easier to select a large-bandwidth wireless network interface suitable for the new network interface. The bearer can also provide a better radio bearer option for the existing network interface of the terminal device when the newly-built radio bearer is a large-bandwidth radio bearer.
