On carrier wave, the second business is optionally carried on a second carrier.When above-mentioned first business and the second service concurrence, such as terminal
Equipment should use the first business, while also use the second business, if reception level of the terminal device on first carrier
It is all satisfied preset access demand with the reception level on the second carrier wave, and terminal device has bigger bandwidth demand at this time,
Such as requested second business of terminal device, when required resource is greater than resource corresponding to the second carrier wave, if this
When first carrier on volume load it is lower (resource of first carrier there are also remaining), then access network equipment can be carried out carrying
Wave polymerization, i.e., be used to carry the second business for the part resource on first carrier.The part of the second business is carried on second at this time
On carrier wave, another part is carried on first carrier.Since terminal device supports carrier wave polymerization, terminal device can be distinguished
First business required for being parsed on first carrier and the second carrier wave and the second business.
That is, access network equipment and terminal device support continuous carrier folding, in narrowband in the implementation
Under carrier capacity is unrestricted (such as there are in remaining situation for the resource of first carrier), carrier wave polymerization property can use, eventually
End equipment can be used simultaneously two carrier resources, ensure the peaking capacity of unit/terminal.The algorithm has ensured that the capacity of network will not
Because carrier wave division is limited, while also having taken into account Deta bearer, the utilization rate of resource is improved.
