Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method for processing a radio bearer and a terminal device.
Background
With the development of access network technology, the 3GPP protocol is continuously perfecting and improving with the progress of communication technology, wherein the 3GPP R15 protocol defines a Dual Connectivity (DC) architecture of Long Term Evolution (LTE) and New Radio (NR). In the early stage of DC architecture application, most network operators adopt LTE and NR Dual Connectivity (EN-DC) architecture in DC architecture. By adopting the architecture, the existing fourth generation mobile communication technology (4G) core network does not need to be updated to a 5G core network, and only the 5G base station needs to be newly added on the basis of the existing 4G base station, so that the 4G +5G combined access service is provided for the terminal, the bandwidth of a wireless bearer is improved, and the effect of improving the data transmission rate is achieved. In other communication networks (e.g., wireless local area networks), there is a method for increasing the bandwidth of the radio bearer, which can also achieve the effect of increasing the data transmission rate.
Taking an EN-DC architecture in the DC architecture as an example, under an EN-DC network, a terminal first accesses the network through a 4G base station to establish Radio Resource Control (RRC) connection. When the 4G base station has a cooperative 5G base station, the 4G base station may reconfigure, by RRC, to add a link resource of the 5G network to a specific 4G radio bearer established by the terminal and the 4G base station, and split the original 4G radio bearer onto a dual link to form a split bearer (split bearer). By splitting the bearer, the uplink data of the user can be transmitted through the 4G and 5G wireless links at the same time, and is distributed to the 4G and 5G cells, and then is converged in the 5G base station, and the downlink data can also be distributed through the 5G base station, and is sent to the terminal through the 4G and 5G cells, and is converged in the terminal. Therefore, the split bearer has larger bandwidth, and the data throughput rate of the split bearer is higher. Such a radio bearer with bandwidth increased by means of configuration of a network side device (e.g., a base station, a wireless router, etc.) may be referred to as a large bandwidth radio bearer.
In the current network architecture, since there is no corresponding protocol to stipulate 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 configure one or some of the radio bearers as the large bandwidth radio bearer, and the large bandwidth radio bearer configured by the network side device may not be a radio bearer for transmitting service data. If the network side device configures an established radio bearer as a large bandwidth radio bearer, and when a data service request is generated by the terminal, it is possible to re-establish a new radio bearer service to transmit service data, and the established large bandwidth radio bearer is not used to transmit service data, for example, as shown in fig. 1, which may result in that the large bandwidth radio bearer cannot be effectively utilized.

In order to solve the problem that a terminal device cannot effectively utilize an established large-bandwidth radio bearer in an existing network architecture, which results in high-quality network resource waste, the embodiment of the present application provides a radio bearer processing method. The embodiment of the application also provides corresponding terminal equipment. The following are detailed below.
Fig. 3 is a schematic diagram of an embodiment of a method for radio bearer processing according to an embodiment of the present application.
As shown in fig. 3, an embodiment of a method for radio bearer processing provided in an embodiment of the present application may include:
301. the terminal device generates a first network interface.
When a data service request is generated in an application processing layer of the terminal device, the data service request carries an Access Point Name (APN), and when the APN carried by the data service request is inconsistent with an APN corresponding to an existing radio bearer, the terminal device requests a network side device to establish a new radio bearer by using the APN carried by the data service request. After the new radio bearer is established, the application processing layer of the terminal device configures a network interface corresponding to the data service request. The first network interface in this embodiment is a network interface that is generated by the terminal device after the new first radio bearer is established.
302. The terminal equipment acquires the parameter information of each radio bearer in the first radio bearer set.
In this embodiment, the first radio bearer set includes a 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 generated by the terminal device correspondingly according to the newly established first radio bearer. It should be noted that the at least one existing second radio bearer included in the first radio bearer set is already established before the first radio bearer is established, where the at least one existing second radio bearer is established for the terminal device by the network side device when the terminal device registers in the access network, and is not actively triggered and established by the terminal device, and the other radio bearers are actively triggered and established by the application processing layer of the terminal device according to requirements. The terminal device may actively trigger the network side device to establish more radio bearers according to a requirement, so as to increase the number of radio bearers in the first radio bearer set, so that the first radio bearer set includes more large-bandwidth radio bearers as much as possible, and thus, the first network interface may be mapped and bound with the large-bandwidth radio bearers as much as possible, thereby improving the utilization rate of the large-bandwidth radio bearers. The function of the terminal device for acquiring the parameter information of each radio bearer in the first radio bearer set is to screen out a large bandwidth radio bearer matched with the service type supported by the first network interface from the first radio bearer set.
303. And the terminal equipment determines a 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 may determine, according to the parameter information of each radio bearer in the first radio bearer set, a service type supported by each radio bearer, for example, a specific service and a general service. The specific service refers to a small part of special services in the data service (for example, a specific IP service, which requires a specific radio bearer to transmit five-tuple information of an IP packet), and this specific service can only transmit service data based on a specific network interface and the radio bearer. The general service refers to most of internet services in data services, and such general service can perform service data transmission based on any network interface and radio bearer. The second set of radio bearers includes radio bearers in the first set of radio bearers that match traffic types supported by the first network interface.
304. And the terminal equipment determines a target radio bearer according to the parameter information of each radio bearer in the second radio bearer set, wherein the target radio bearer is the radio bearer of which the bandwidth value in the second radio bearer set meets the preset condition.
In this embodiment, after the terminal device determines the second set of radio bearers, the terminal device may determine, from the second set of radio bearers, a target radio bearer whose bandwidth value meets a preset condition to perform mapping 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 a terminal device in an access network scenario, or a radio bearer with bandwidth increased by other means in other traffic scenarios. In general, the number of such large bandwidth radio bearers is small, so the terminal device may 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-established first radio bearer, the service types supported by the first network interface and the first radio bearer are also necessarily consistent, that is, the second radio bearer set also includes the first radio bearer, and then there may be a case where the target radio bearer is the first radio bearer.
305. And the terminal equipment maps and binds the target radio bearer with the first network interface.
In this embodiment, after the terminal device determines a target radio bearer, which is an optimal radio bearer for the first network interface, the terminal device performs mapping binding on the target radio bearer and the first network interface, so that the service data is transmitted based on the first network interface and the target radio bearer.
In this embodiment, when generating the first network interface, the terminal device may map and bind the first network interface with the target radio bearer, so that a data service of the terminal device based on the first network interface may transmit data through the target radio bearer, thereby making full use of a characteristic of a large bandwidth of the target radio bearer, improving a data throughput rate during service data transmission, and improving network performance and an effective utilization rate of the large bandwidth radio bearer.
In a specific embodiment, when a new large-bandwidth radio bearer is established, the terminal device may further perform mapping binding again on some network interfaces that have already established mapping binding relationship with a radio bearer having a smaller bandwidth value and the new large-bandwidth radio bearer, so as to fully utilize the network resources of the newly established large-bandwidth radio bearer.
In a specific embodiment, the parameter information of the radio bearer may include: the radio bearer may include parameters such as Dual Connectivity (DC) status information, quality of service (QOS) parameters, QOS Class Identifier (QCI), internet protocol address (IP), and Traffic Flow Template (TFT) corresponding to the radio bearer.
The contents of the above embodiments will be described in further detail below.
Fig. 4 is a schematic diagram of another embodiment of a method for radio bearer processing according to an embodiment of the present application.
As shown in fig. 4, another embodiment of the method for radio bearer processing provided in this 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, which is not repeated herein.
402. The terminal equipment acquires the parameter information of each radio bearer in the first radio bearer set.
In this embodiment, the parameter information of each radio bearer may include: each radio bearer corresponds to DC state information, QOS parameters, QCI, IP address, and TFT.
403. And the terminal equipment determines the service type supported by each radio bearer in the first radio bearer set according to at least two items of the service quality grade identification QCI, the IP address and the service flow template TFT corresponding to each radio bearer in the first radio bearer set.
In this embodiment, the QCI is used to indicate indexes such as service delay and packet loss rate of the radio bearer, and when a value of the QCI corresponding to the radio bearer is between 5 and 9, it indicates that the radio bearer can support a general service, otherwise, it indicates that the radio bearer can only support a specific service. The IP address and TFT are used to define five tuple information of IP packets that the radio bearer can transmit. If there is a TFT in the parameter information corresponding to the radio bearer, it indicates that the radio bearer can only support a specific service, and if there is no TFT, it indicates that it may support a general service. The service type supported by the radio bearer can be judged through the parameter information combination formed by the QCI, the IP address and the TFT.
404. The terminal device determines the type of service supported by the first network interface.
In this embodiment, specifically, the terminal device may determine the service type supported by the first network interface according to the routing information corresponding to the first network interface, where the routing information corresponding to the first network interface is correspondingly generated when the terminal device generates the first network interface. The terminal device may determine the service type supported by the first network interface by obtaining the routing information. For example, assuming that the routing rule included in the routing information corresponding to the first network interface is a general routing rule, and there is no special identifier for limitation, and the routing table included therein has a default route, it may be said that the first network interface supports general services, otherwise, it may be said that the first network interface can only support specific services.
405. And the terminal equipment determines a 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 embodiment, according to whether each radio bearer in the first radio bearer set and the first network interface simultaneously support a general service or a specific service, a radio bearer matching the service type supported by the first network interface can be determined, and the second radio bearer set can be determined.
406. And the terminal equipment determines the target radio bearer according to the DC state information or QOS parameters corresponding to each radio bearer in the second radio bearer set.
In this embodiment, the DC status information corresponding to each radio bearer in the second set of radio bearers may indicate whether the radio bearer is a split bearer. When the DC status information corresponding to one 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 set of radio bearers can be used as a reference for the bandwidth size of all radio bearers in the second set of radio bearers. Specifically, the maximum 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 manager, and the larger the maximum rate of the radio bearer under the control of the core network manager indicated by the AMBR is, the larger the bandwidth of the radio bearer is. In this embodiment, the terminal device may select the radio bearer with the largest bandwidth as the target radio bearer according to the QOS parameter.
407. And the terminal equipment maps and binds the target radio bearer with the first network interface.
In this embodiment, the content of step 407 is similar to that of step 305, and reference may be made to the related description of step 305, which is not repeated herein.
408. And the terminal equipment sends a radio bearer establishment request to the network side equipment, wherein the radio bearer establishment request is used for requesting the network side equipment to establish a new third radio bearer for the terminal equipment.
In this embodiment, the terminal device may actively trigger the network side device to establish a new radio bearer, that is, a third radio bearer, by sending a radio bearer establishment request to the network side device. The purpose of newly building the third rb is to increase the number of rbs in the first rb set in the above embodiment, thereby increasing the screening range of the target rb, so that the network interface generated by the terminal device has a larger rb selection space.
409. And if the bandwidth value of the third radio bearer is greater than the radio bearer corresponding to the second network interface and is matched with the service type supported by the second network interface, the terminal equipment maps and binds the second network interface and the third radio bearer.
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 without large bandwidth characteristics, and 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 matched with the service type supported by the second network interface, the terminal device may map and bind the second network interface and the third radio bearer again, as shown in fig. 5. Therefore, the original data service based on the second network interface can transmit service data through the newly-built third radio bearer, the data transmission rate can be improved, and the network resource of the newly-built third radio bearer is fully utilized.
In this embodiment, the terminal device may actively trigger establishment of more radio bearers, so as to improve a selection space of the radio bearers, and when the terminal device generates a new network interface, it is easier to select a large-bandwidth radio bearer suitable for the new network interface, and when the new radio bearer is a large-bandwidth radio bearer, it may also provide a better radio bearer selection for the existing network interface of the terminal device.
The foregoing describes a method for radio bearer processing provided in this embodiment, and the following describes a terminal device provided in this embodiment.
