A method for implementing message authentication is provided. The method includes the following steps. A path by which a destination address of a message to be sent can be reached is determined. A signature processing is performed on the message to be sent according to a private key corresponding to the path, so as to obtain an authentication code. The message to be sent and the authentication code are sent through the path.

A method, a communication system, and a network entity for group handover are provided. The method includes the following steps. A first tunnel connection is established between a mobile relay station (MRS) and a serving entity (SE). A target entity (TE) obtains group information about the group to be handed over, and the group information includes information about a first tunnel. According to the group information, the TE configures information about a second tunnel for the group, and the information about the second tunnel is required for group handover. The group nodes are handed over from the SE to the TE according to the information about the second tunnel. Thereby, the group information that needs to be transmitted in a handover process is reduced, and problems resulting from the number of handovers can be avoided.
