Detailed Description
In the embodiment of the invention, the network side frequency band is sent to the terminal, the terminal frequency band combination (namely the frequency band combination supported by the terminal) from the terminal is received, double connection can be carried out based on the terminal frequency band combination, and then the data transmission capability of the second system is fully utilized.
The terminal frequency band combination is obtained by matching all frequency band combinations supported by the terminal with the network side frequency band, and the network side frequency band is used for indicating all or part of the frequency bands accessed by the first system and/or the second system which support the terminal, so that the terminal frequency band combination is different in different connection scenes and is generated according to the current network side state and the current terminal state. Therefore, the pertinence of the terminal frequency band combination is stronger, the system resources occupied by the transmission terminal frequency band combination are less, and the efficiency is higher.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 1 is a flowchart of a dual-system dual-connection method in an embodiment of the present invention, which is applicable to a network side, and includes the following steps:
step S11, a network side frequency band is issued to a terminal, the terminal has access to a first system, the network side frequency band is used for indicating all or part of frequency bands which the first system and/or a second system support terminal access;
step S12, receiving a terminal frequency band combination from the terminal, wherein the terminal frequency band combination is obtained after all frequency band combinations supporting dual-system dual connection of the terminal are matched with the network side frequency band, and the dual-system dual connection refers to accessing a second system based on the first system.
The network side frequency band sent to the terminal may be sent to the terminal by a base station of the first system, and the network side frequency band may only include a frequency band that the first system or the second system supports the terminal to access, for example, may only include all or part of a frequency band that the first system supports the terminal to access, or may only include all or part of a frequency band that the second system supports the terminal to access.
The network side frequency band may include all or part of the frequency bands that the first system supports the terminal access, and may also include all or part of the frequency bands that the second system supports the terminal access. The frequency band specifically included in the network side frequency band may be determined according to the actual deployment scenario needs.
After receiving the frequency band combination from the terminal, the network side frequency band may perform the next dual-system dual-connection configuration to indicate that the terminal accesses the second system.
In specific implementation, the network side frequency band may be sent to the terminal through RRC signaling, or the terminal frequency band combination from the terminal may be received through RRC signaling.
As described above, the specific frequency band included in the network side frequency band may be determined according to the requirements of the specific deployment scenario, and the terminal matches the network side frequency band and the frequency band combination preset by the terminal, so as to obtain a targeted terminal frequency band combination.
The terminal can match the network side frequency band and a preset frequency band combination to obtain a terminal frequency band combination. The preset frequency band combination of the terminal may include a first system frequency band in which the terminal supports dual-system dual connection, and a second system frequency band which can be combined with the first system frequency band so that the terminal performs the dual-system dual connection.
The following further describes the network-side frequency bands including different frequency bands and the corresponding terminal frequency bands.
When the network side frequency band only includes all or part of the frequency bands which the first system supports the terminal to access, the terminal can match the network side frequency band with a preset frequency band combination to obtain a terminal frequency band combination.
For example, the network-side frequency band includes a frequency band a and a frequency band b, and then the frequency band a and the frequency band b may be used to match a frequency band combination preset by the terminal, so as to obtain a frequency band combination at least including a or b, for example, the following frequency band combinations may be obtained: { a + x }, { a + y }, { a + b + z }, { a + u }, and { b + u }. The frequency band x, the frequency band y, the frequency band z and the frequency band u are frequency bands of a second system. The frequency band combination { a + b + z } may indicate that the terminal supports dual connection of the frequency band a and the frequency band b of the first system with the frequency band z of the second system. That is, dual connectivity is not limited to being on two frequency bands.
After receiving the terminal frequency band combination, if it is determined that the actual network can support at least one of the terminal frequency band combinations reported by the terminal, the method has the premise of further dual-connection related configuration. Whether to perform further configuration or not can be judged according to preset conditions, and if the preset conditions are met, the further configuration is performed.
The preset condition may include a first system frequency band included in the terminal frequency band combination by the serving cell frequency band of the terminal. For example, the terminal frequency band combination reported by the terminal is { b + u }, the network side can support dual connection of the first system frequency band b and the second system frequency band u, and the frequency band of the terminal serving cell is the frequency band b, so that the frequency band of the terminal serving cell is included in the first system frequency band in the terminal frequency band combination.
The preset condition may also include other conditions such as signal strength. If the preset condition is met, the network side can be further configured to perform dual connectivity.
Before step S11, the frequency bands that the second system supports terminal access may also be determined.
The network side frequency band may include all or part of the frequency bands that the second system supports the terminal access, and may also include all or part of the frequency bands that the first system supports the terminal access. The terminal matches a preset frequency band combination according to the network side frequency band to obtain a terminal frequency band combination which comprises both the frequency band supported by the first system in the network side frequency band and the frequency band supported by the second system in the network side frequency band.
For example, the network-side frequency band includes a frequency band x, a frequency band y, a frequency band z, a frequency band a, and a frequency band b, where the frequency band a and the frequency band b are a first system frequency band, and the frequency band x, the frequency band y, and the frequency band z are a second system frequency band. The terminal is matched with the network side frequency band and a preset frequency band combination, and the frequency band combination which not only contains the frequency band x, the frequency band y and the frequency band z, but also contains the frequency band a and the frequency band b is selected from the frequency band combination. Assume that the following band combinations are selected: and the frequency band combinations are reported to the network side as the terminal frequency band combination.
The network side frequency band may also include only all or part of the frequency bands that the second system supports the terminal to access. The terminal can also match a network side frequency band only including the second system frequency band with a frequency band combination preset by the terminal to obtain a terminal frequency band combination.
For example, the network side frequency band includes a frequency band x and a frequency band y, and after receiving the request, the terminal performs matching to obtain a frequency band combination supporting dual-system dual connection at least including the frequency band x or the frequency band y as a terminal frequency band combination, for example, the following frequency band combinations are obtained: { a + x }, { b + y }. After receiving the terminal frequency band combination, the network side may further perform dual connectivity configuration if it is determined that the network side can support at least one of the frequency band combinations and the predetermined condition is satisfied.
In the embodiment of the present invention, the first system frequency band is a frequency band that the first system supports the terminal access, and the second system frequency band is a frequency band that the second system supports the terminal access.
When the base station of the first system and the base station of the second system provide the dual connectivity service for the terminal, an interface may be provided between the base station of the first system and the base station of the second system, and the base station of the first system and the base station of the second system may obtain the frequency band related information of the other party through the interface.
After receiving the terminal frequency band combination, for example, after the base station of the first system receives the terminal frequency band combination, it may further determine whether the base station of the second system can cooperate with the base station of the first system to support the terminal frequency band combination to perform dual connectivity. And determining whether to perform the next double-connection configuration according to the judgment result. If it is determined that dual connectivity cannot be supported in the terminal frequency band combination, the terminal may not be configured with the measurement of the second system.
Before the network side frequency band is sent to the terminal, the terminal can be determined to support dual-system dual-connection. If the terminal can not support dual-system dual-connection, the network side frequency band is not sent to the terminal, the inquiry of the terminal frequency band combination is not carried out, and other subsequent steps are not carried out, so that the signaling overhead can be further saved.
The terminal usually supports dual connectivity between different system base stations in a specific frequency band, and if the terminal does not support dual connectivity between a first system base station and a frequency band of a second system base station in the coverage area of the first system base station, subsequent measurement configuration signaling for the dual connectivity is unnecessary.
In the embodiment of the present invention, if the terminal frequency band combination is not received, it may be considered that the terminal does not support the first system base station and the frequency band of the second system base station within the coverage area thereof to establish dual connection, so that subsequent measurement and configuration may not be performed, and system resources may be further saved.
The first system and the second system in the embodiment of the invention can be an LTE system and a 5G system respectively. For example, an LTE system may serve as the first system, and a 5G system may serve as the second system; alternatively, the 5G system may serve as the first system, and the LTE system may serve as the second system.
In the initial stage of deployment of the 5G system, the LTE system is usually not deployed independently, and at this time, the LTE system is used as the first system, the 5G system is used as the second system, so that the close cooperation between the 5G system and the LTE system can be established, the neighbor measurement of the 5G system by using the LTE system configuration middle terminal is used for performing the dual-connection between the LTE system and the 5G system, and the data transmission capability of the 5G system is fully utilized.
