ForewordWith continuous construction of networks and continuous development of radio services the operator needs to expand thedevelopment of radio services, the operator needs to expand the capacity of the existing network.
Due to the network construction strategy at the early stage and the difference between the frequency band used at the early stage and the frequency band used for capacity expansion, the function and performance requirements of the network whose capacity isand performance requirements of the network whose capacity is to be expanded are different from those of the existing network.
Based on different scenarios and requirements, Huawei puts forward a series of multi-band and multi-carrier solutions.

After using other frequency bands or other carriers to expand the capacity of the existingAfter using other frequency bands or other carriers to expand the capacity of the existing UMTS network, the network operator should pay attention to the following points:
Impact of capacity expansion on the experience of the existing users
Load balancing status of the network before and after capacity expansion
Performance requirementsDifferent from the single-band networking mode, the operator should pay special attention to the following points in the multi-band and multi-carrier networking mode:
Access success rate: retry access success rate between different frequency bands and carriers
Handover success rate: handover success rate between different frequency bands and carrierscarriers
Access delay: access delay upon redirection

Border areas between the low frequency band and the high frequency band are configured as
inter-frequency neighbor cells. The version later than R10 supports 64 inter-frequency neighbor
cells, unlimited number of frequencies, and a maximum of three frequency bands.

For the handover from UMTS900 to UMTS2100, if UMTS2100 has two frequencies, the frequency F1 is used as the preferred cell for coverage based inter-frequency handover Infrequency F1 is used as the preferred cell for coverage based inter-frequency handover. In this case, UMTS900 only needs to be configured with a single inter-frequency neighbor
cell F1. (Among the two frequencies, if only F1 supports the HSPA+R99 hybrid service, F1
is recommended.))

Aptitudinal camping on F2In case of capacity expansion through discontinuous coverage of UMTS2100, the
signals covering the UMTS900 cell are slightly stronger than those covering the
UMTS2100 cell. If a UE is prone to camp on the UMTS900 cell, when the UE is blind
handed over to the UMTS2100 neighbor cell covered by weak signals during the
DRD process at the RAB stage in connection state, DRD fails. Therefore, aptitudinal
camping on UMTS2100 is recommended.

Summaryy
Multi-band and multi-carrier capacity expansion is based on
the current networking scenarios. The purpose of capacity
expansion is to compensate for blind areas or increase the
capacity of hotspot areas, and optimize the user camping
policy, mobility management, service bearer, access policy,
d i b d hand connection state management based on the parameter
configuration policy for algorithms such as the load control
