Description

动态配置数字信号处理器算法通道的方法、 设备及系统
[1] 技术领域
[2] 本发明涉及通信技术领域, 尤其涉及一种动态配置数字信号处理器算法通道的 方法、 设备及系统。
[3] 发明背景
[4] TC (Transcoder, 码变换器) 单元主要用于语音编解码, 如图 1所示, 为所述 T
Figure imgf000003_0001
Controller, 基站控制器) 网元和 MSC (Mobile Service switching
Figure imgf000003_0002
Processor, 数字信号处理器) 器件来实现其语音编解码功能。 每块 DSP以资源池 方式实现对语音编解码算法的支持。 在 GSM (Global System
Mobile, 全球移动通信系统) 中支持的语音编解码算法包括: FR (Full rate, 全速率) 、 EFR (Enhance FR, 增强型 FR) 、 HR (Half
rate, 半速率) 、 AMR (Adaptive Multi- Rate, 自适应多速率) 等。
[6] 如图 2所示, 釆用所述资源池方式, 每个 DSP即为一个小的完备的资源池, 支 持上述所有业务类型, DSP个体之间不存在差异, 根据 DSP支持各种业务的性能 预先确定了各 DSP支持的通道数 (假设为 40路) , 各个 DSP构成的小资源池聚合 后再统一由上层管理模块进行管理。
[7] 在实现本发明过程中, 发明人发现现有技术一至少存在如下缺点:
[8] 在设定 DSP支持的通道数吋, 由于 DSP无法确定各种业务所占的比例, 因此, 为兼顾各种算法, DSP需要取其所支持的算法中占用资源最大的算法来计算。 这 种设定通道数的方法使得 DSP性能得不到饱和运用, 存在一定的资源浪费, DSP 的通道支持数目受到所支持的各种算法中资源占用最大的一种算法的限制。 例 如, 在图 2中, 釆用占用资源最大的 HR算法计算支持通道数, 而由于存在例如 F R这样占用率只接近 50%的算法, 并且如果当前 DSP实际业务中 FR算法占较大的 比例, 则 DSP资源不能得到饱和应用, 造成了近一半的资源浪费。
与本发明相关的现有技术二的技术方案为:
将 DSP之间支持的业务算法进行差异化、 单一化, 即每个 DSP只支持一种算法 , 先组建不同算法的资源池, 再聚合后统一由上层管理模块进行管理。 如图 3所 示, 具体业务算法分配方案为: 先根据单一业务算法计算每个 DSP支持的通道数 , 发布对应的算法加载软件, 然后根据各个 DSP支持的算法建立各种算法的资源 池, 由资源管理模块在各个算法资源池中进行选取分配; 同吋, 在系统运行过 程中, 各种算法的资源池大小需要根据实际用户情况进行动态调整。
在实现本发明过程中, 发明人发现现有技术二至少存在如下缺点:
各种算法资源间不得共用, 在实际用户情况改变吋, 需要进行资源池的动态调 整, 即重新加载支持某种算法的 DSP软件使其满足当前用户业务需要, 再划分到 该业务的资源池来满足业务容量的需求, 增加了控制复杂度, 同吋加载的 DSP算 法软件需要根据业务算法种类而分, 版本维护成本增加, 当出现突发业务比例 变换吋, 可能因比例不能得到及吋调整而造成某种业务算法资源池紧缺, 从而 不能及吋提供业务服务。
