Abstract: A method for network equipment to generate authentication information in the mobile communication system, at least includes the following process: set security key corresponding to mobile terminal in network equipment; and network equipment generates authentication information corresponding to mobile terminal based on said security key and a random number. And, a method for mobile terminal to authenticate communication network in the mobile communication network, at least includes the following process: set security key corresponding to mobile terminal in the mobile terminal; and after the authentication information from network equipment is received, the mobile terminal determines whether the network authentication succeeds based on said security key set by the mobile terminal and the authentication information.

Abstract: A communication method, system, and apparatus are applied to the field of communications technologies. The communication method includes presetting first correspondence between a user identifier and an extension number in a VoIP server. After the VoIP server receives a call request and if the call request contains a called extension number, a called user identifier is acquired according to the called extension number and the preset first correspondence. The call request is sent to a first client corresponding to the called user identifier, so that the first client is capable of forwarding a call to a voice communication telephone set connected to the first client.

Abstract: A system for realizing the reception of a incoming call number by a terminal includes a CDMA network and a HRPD network providing service support for the terminal, respectively, where an MSC in the CDMA network connects with an access network of the HRPD network via interface A1. A method for realizing the reception of a incoming call number by a terminal in advance includes: the MSC in the CDMA network transmitting the incoming call number of a paging to the access network of the HRPD network through interface A1; the access network forwarding the incoming call number of this paging to the called terminal; the called user deciding whether to accept the incoming call based on the received incoming call number. Accordingly, the switching between HRPD and CDMA2000 1x can be avoided when the user decides not to accept the incoming call.

Abstract: A method for implementing the media gateway function is disclosed by the embodiment of the present invention, including: receiving a first signaling message; determining to perform a processing of a base station application layer or a processing of a media gateway control application layer according to a Simple Control Transmission Protocol (SCTP) link, wherein the SCTP link is indicated by the first signaling message; if determine to perform the processing of the media gateway control application layer, routing traffic data to a destination device. A radio access control device and a radio access system according to the above mentioned method are further disclosed. According to the embodiment of the present invention, the exchange number of an IP packet is reduced, and the bearer is separated from the control.
