一种呼叫处理方法及装置
摘要：
本发明涉及通信技术，特别涉及扩频码分多址系统中为新到达呼叫指配信道化码的呼叫处理方法及装置，以解决现有技术中无法通过选择OVSF码来降低PAPR的问题。所述方法主要包括：产生码长与到达呼叫所需数据速率相应的可指配空闲OVSF码；确定每一个可指配空闲OVSF码的影响系数，该影响系数为可指配空闲OVSF码与所有忙码分别相乘形成的一组组合码中，最大游程长度大于等于8的组合码个数；选择最小影响系数对应的一个可指配空闲OVSF码作为信道化码并指配给所述呼叫。所述装置主要包括码生成模块、码分析模块和码指配模块。使用本发明所述方法选择的可指配空闲OVSF码，与使用其他可指配的空闲OVSF码相比PAPR最低。
摘要（英）：

This invention relates to a call process method and a device for allocating channel codes for newly arrived calls in a SCDMA, in which, the method includes: generating allocatable idle OVSF codes corresponding to the data rate needed by step length and the arrived call, determining the influence factor for each OVSF code, which is the number of combined codes with the greatest travel length of 8 in a set of combined codes formed by multiplying the OVSF codes and all busy codes, an allocated idle OVSF code corresponding to the least influence factor is selected as a channel code to be allocated to the call, said device includes a code generation module, a code analyzing module and a code allocating module.
