The independent signal that only signal and a signal type are C, can also be converted into the independent signal that three signal types are B, very
The independent signal that signal type is D can be extremely converted into, how to carry out conversion depending on transformation rule set in advance to determine.
Next expansion description further will be carried out to the transformation rule in step S201.Transformation rule is typically and network rings
The demand in border is related, and transformation rule can be divided at least three kinds of different situations by difference according to demand.
Step S201 the first situation：
The signal type being converted to according to transformation rule belongs to the independent signal that the mixing module receives
Any one or more of signal type.
In this case, the signal for the independent signal that any signal type receives with mixing module can be converted into
Type is related, that is to say, that if mixing module receive independent signal signal type there was only A, B and C if, then pass through
It is combination of the signal type for the independent signal of any one or more in A, B and C that what transformation rule was drawn, which is also only possible to, and
And the number of independent signal of the number for the independent signal changed out with receiving is identical.Specifically which kind of transformation rule can be pre-
First set.
Step S201 second of situation：
The signal type being converted to according to transformation rule is used to represent the independent letter handled by the processing module
Number type any one or more.
In this case, can be converted into any signal type with and the processing module phase that is connected of the separation module
Close, in step S104 it has been described that the processing module that what is referred to is relevant with the flow direction of data flow, that is to say, that such as
When processing module described in fruit is referred to as the signal processing chip in local, the type for the independent signal changed out is just and at signal
The signal type that reason chip can be handled is related, for example local only has the signal processing chip that energy process signal type is A, that
The independent signal received is converted into the independent signal that signal type is A by hybrid chip, if local can only be located
Manage signal type be A and B signal processing chip, the signal type that hybrid chip receives the independent signal of three be respectively B,
C and D, then the independent signal changed out by transformation rule both can be the independent signal that a signal type is A and two
The list that the independent signal and a signal type that the independent signal or two signal types that signal type is B are A are B
Only signal, is possibly even the independent signal that three signal types are A or the independent signal that three signal types are B etc.,
The number of independent signal of the number for the independent signal changed out with receiving is identical.
If the processing module is referred to as the processing component of network side, the type of the independent signal changed out is just and place
The signal type that can handle of reason component is related, can be the signal type that processing component can be handled any one or more
Combination, and the number of independent signal of the number for the independent signal changed out with receiving is identical.Specifically which kind of is changed
Rule can be preset.
Step S201 the third situation：The signal type being converted to according to transformation rule belongs to be passed according to data
What defeated demand determined.
In such case, described data transfer demands can be data transmission bauds, data transfer energy consumption etc., with data
Exemplified by transmission speed, if the signal type that mixing module receives three independent signals is respectively A, B and C, wherein class signal
The data transmission bauds of type A independent signal is that 1M is per second, and the data transmission bauds of signal type B independent signal is every for 800K
Second, the data transmission bauds of signal type C independent signal is per second for 15K, in order to improve data transmission bauds, by signal type
B independent signal and signal type C independent signal are converted to signal type A independent signal by transformation rule, obtain three
Individual signal type A independent signal.Transformation rule can also be selected according to other demands, being specifically which kind of transformation rule can be pre-
First set.The number of independent signal of the number for the independent signal changed out with receiving is identical.
From the present embodiment as can be seen that independent signal by the multiple unlike signal types received under heterogeneous network environment
A mixed signal is mixed into according to certain mixing rule very much so that terminal can receive the mixed signal using an equipment,
Mixing rule during by the mixed signal received to mix reversely isolates an independent signal for forming the mixed signal
Or multiple different types of independent signals and corresponding processing module is sent to, so that terminal is provided with heterogeneous network ring
The ability of the different types of independent signal of simultaneous transmission under border.
Before the independent signal received is mixed, changed individually with corresponding transformation rule according to different demands
The signal type of signal, such as can be handled according to the signal type of the independent signal received, local processing module
Signal type or transmission speed etc., thus further increase the scope of application of technical solution of the present invention.

Machine only has the signal processing chip that energy process signal type is A and B, and hybrid chip receives the class signal of the independent signal of three
Type is respectively B, C and D, then the independent signal changed out by transformation rule both can be that a signal type is the independent of A
The independent signal and a class signal that the independent signal or two signal types that signal and two signal types are B are A
Type is B independent signal, is possibly even the independent signal that three signal types are A or the list that three signal types are B
Only signal etc., the number of independent signal of the number for the independent signal changed out with receiving is identical.
If the processing module is referred to as the processing component of network side, the type of the independent signal changed out is just and place
The signal type that can handle of reason component is related, can be the signal type that processing component can be handled any one or more
