Claim:
1. A security processing method in a network handover process of a mobile terminal from a source network to a target network, the method comprising: receiving, by a mobile switching center (MSC) server in the source network, a handover request message; generating, by the MSC server, a random value; generating, by the MSC server based on the random value, a target key in the target network, wherein the target network is any one of a high speed packet access (HSPA) network or a long term evolution (LTE) network; sending, by the MSC server, security information comprising the target key to a target network node regardless of whether the target network is the HSPA network or the LTE network, wherein the target key is used for a target access network node to perform, according to the target key, secure communication processing on a mobile terminal handed over to the target network; receiving, by the MSC server, a handover response message sent by the target network node, wherein the handover response message carries a transparent container which is generated by the target access network node; and sending, by the MSC server, a handover command to the mobile terminal for the mobile terminal to access the target network, wherein the handover command carriers the random value and the transparent container.
