Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of transmission, processing method, network equipment and terminal of PWS master's advertised information.
Background technology
In order to make the user can receive timely and accurately alarm, warning and key message about disaster and other emergency, 3GPP (3rd Generation Partnership Project, third generation partner program) defined PWS (Public Warning System, public warning system) business.When meeting with disasters such as earthquake, tsunami, hurricane and outdoor fire disaster, this business can so that the public can take suitable action with avoid own and the household severely injured or dead, or suffer the heavy losses of property.
The different communication network of 3GPP definition, such as GSM (Global System of Mobile communication, global system for mobile communications), UMTS (Universal Mobile Telecommunications System, universal mobile telecommunications system) and LTE (Long Term Evolution, Long Term Evolution) all support PWS professional, and the professional CBS (Cell Broadcast Service, cell broadcaste service) that adopts of regulation PWS carries transmission.Its framework as shown in Figure 1, the following explanation of the function of each network element:
Cell Broadcast Entity (Cell Broadcast Entity is called for short CBE): the communication network that does not belong to the 3GPP definition.CBE is responsible for CBS (Cell Broadcast Service, cell broadcaste service) is formatd, and comprises CBS message is divided into the different pages;
CBC (Cell Broadcast Center is called for short CBC): belong to the part of core network, can link to each other with a plurality of CBE.CBC is responsible for the management of CBS message, comprising: determine the time that CBS message is gone on the air; Determine the time that CBS message is gone off the air, and indicate each BSC (Base Station Controller, base station controller)/RNC (Radio Network Controller, radio network controller) CBS message of going off the air; Determine the time interval that CBS message is repeated to broadcast; Determine the CBCH of broadcasting CBS message etc.For the GSM network, CBC links to each other with the BSC that is positioned at Radio Access Network, and interface is IuBC; For the UMTS system, CBC links to each other with the RNC that is positioned at Radio Access Network by the IuBC interface; For the LTE system, the MME of CBC and core net (Mobility Management Entity, Mobility Management Entity) links to each other, and interface is S1BC.After the alert message that CBC sends the CBE that receives is configured and encapsulates, send to BSC (gsm system), RNC (UMTS system) and the MME (LTE system) of involved area, BSC/RNC/MME is transmitted to it base station of each system again, and (gsm system is BTS (Base Transceiver Station, base transceiver station), the UMTS system is NodeB (Node B), the LTE system is eNB (enode b)), by base station broadcast to the user.
The CBS business of definition all sends at broadcast channel at present.And present broadcast channel is without any safety precautions.The assailant can distort alert message, perhaps receive alert message after, reset in another impregnable area, thereby in the public, cause unnecessary panic and chaotic.
In order to prevent the appearance of this situation, 3GPP determines PWS is carried out safeguard protection, namely by using the method for digital signature field and timestamp, introduces signature algorithm and key managing project.After terminal is received broadcast warning message, can at first authenticate this alert message, only after authentication success passes through, be sure of that just it is an effective alert message.
In order to make security intensity reach certain rank, namely be not easy victim and break through, 3GPP SA3 working group thinks that proper security information need to take 56 bytes at present.If use security information less than the algorithm of 56 bytes, such as the algorithm of 40 bytes, the assailant can break through than being easier to, and does not reach the protection effect of expection.And the 3GPP maximum length that RRC (Radio Resource Control, Radio Resource control) agreement reserves to security information of eating dishes without rice or wine is 43 bytes, can not satisfy the demand of security intensity.Because this parameter length is subject to TB (Transport Block, the transmission block) size of physical layer in the RRC agreement, so this length can not increase.
