Abstract  Abstract

The invention provides a safety capacity negotiation method application time to move a switch for safety capacity negotiation process a following step: A switching to the second network to the first network requests; B. selecting the access network entity of the second network the corresponding security capability or the second network access network entity and a core network entity respectively select the corresponding security capability; and c. the second network sends the selected security capability through the first network to the user equipment UE. The invention also claims a system of security capability negotiation. The invention can avoid switching from 2G/3G to LTE network the MME must know the corresponding security capability of the eNB by some way and avoid switching from the LTE network to the 3G network introducing a new requirement to the SGSN.
