It needs to be determined that.
After receiving the frequency range for carrying out self terminal combination, the dual system dual link that network side frequency range can carry out next step is matched
It sets, second system is accessed with instruction terminal.
In specific implementation, network side frequency range can be issued to terminal by RRC signaling, can also be connect by RRC signaling
Receive the terminal frequency range combination from the terminal.
As previously mentioned, the specific frequency range that network side frequency range includes can be determined according to the demand of specific deployment scenario, terminal
Matching network side frequency range and the preset frequency range combination of terminal, to obtain targeted terminal frequency range combination.
Terminal can be combined with matching network side frequency range and preset frequency range, to obtain the combination of terminal frequency range.Terminal is preset
Frequency range combination may include the first system frequency range that terminal supports dual system dual link, and can be with the first system frequency range
It is combined so that the terminal carries out the second system frequency range of the dual system dual link.
It is carried out further to comprising the diverse network side frequency range of frequency range and corresponding terminal frequency range individually below
Explanation.
When network side frequency range only includes all or part of frequency range that the first system supports terminal access, terminal can be with pair net
Network side frequency range and the combination of preset frequency range, obtain the combination of terminal frequency range.
For example, network side frequency range includes frequency range a and frequency range b, then can use frequency range a and the reflexless terminal frequency range b is default
Frequency range combination, obtain including at least a or the frequency range combination comprising b, such as the combination of available following frequency range: { a+x }, { a
+y},{a+b+z},{a+u},{b+u}.Wherein, frequency range x, frequency range y, frequency range z, frequency range u are the frequency range of second system.Groups of frequency bands
Closing { a+b+z } can support the frequency range a and frequency range b of the first system and second system frequency range z to carry out dual link with instruction terminal.?
That is, dual link is not limited to carry out in two frequency ranges.
After receiving the combination of terminal frequency range, however, it is determined that the terminal frequency range combination that real network can support terminal to report
At least one then has the premise for carrying out the further relevant configuration of dual link.Whether further configured, Ke Yijin
The judgement of row preset condition is further configured if meeting preset condition.
Preset condition may include that the serving cell frequency range of terminal is contained in the first system frequency range in the combination of terminal frequency range.
For example, the terminal groups of frequency bands that terminal reports is combined into { b+u }, network side can support the first system frequency range b and second system frequency range u
Dual link, the frequency range of terminal service cell is frequency range b, then the serving cell frequency range of terminal is contained in the combination of terminal frequency range
The first system frequency range.
Preset condition can also including signal strength etc. other conditions.If meeting preset condition, network side can be with
It is further configured, to carry out dual link.
Before step S11, it can also determine that the second system supports the frequency range of terminal access.
Network side frequency range can also not only include all or part of frequency range that second system supports terminal access, but also including first

Close, frequency range combination in select not only comprising frequency range x, frequency range y, frequency range z but include frequency range a, frequency range b frequency range combine.Assuming that choosing
Following frequency range combination out: these groups of frequency bands cooperations then can be that the conjunction of terminal groups of frequency bands reports to by { a+x }, { b+y }, { a+b+z }
Network side.
Network side frequency range can also only include all or part of frequency range that second system supports terminal access.Terminal can also be with
Only the network side frequency range including second system frequency range is combined with the preset frequency range of terminal for matching, obtains the combination of terminal frequency range.
