    摘要: An emergency call-based security algorithm negotiation method and apparatus are disclosed. The method comprises the following steps: after receiving an attachment request from a User Equipment (UE) and determining that the attachment request is an emergency attachment request, a network side sets UE security capabilities to support a null algorithm only; or, the network side determines that the UE security capabilities included in the attachment request support the null algorithm only; performing Non-Access Stratum (NAS) and Access Stratum (AS) selection processing taking the null algorithm as a security algorithm for the user equipment. A mobility management entity (MME) and an evolved Node-B (eNB) can perform security negotiation directly on the basis that the user equipment only supports the null algorithm when the NAS and NA security negotiation is performed, so that the access efficiency and the call completing rate of emergency calls are improved.
