The different communication network of 3GPP definition; Like GSM (Global System of Mobile communication; Be global system for mobile communications), UMTS (Universal Mobile Telecommunications System, i.e. UMTS) and LTE (Long Term Evolution, i.e. 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 is as shown in Figure 1, and the function of each network entity is explained as follows:
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: confirm the time that CBS message is gone on the air; Confirm the time that CBS message is gone off the air, and indicate each BSC/RNC CBS message of going off the air; Confirm the time interval that CBS message is repeated to broadcast; Confirm the CBCH of broadcasting CBS message etc.For the GSM network, CBC links to each other with the BSC (Base Station Controller, base station controller) that is positioned at Radio Access Network; For the UMTS system, CBC links to each other with the RNC (Radio Network Controller, radio network controller) that is positioned at Radio Access Network through the Iu interface; For the LTE system, the MME of CBC and core net (Mobility Management Entity, Mobility Management Entity) links to each other.After CBC receives the warning information of CBE transmission; Be configured and encapsulate; Send to BSC (gsm system), RNC (UMTS system), the MME (LTE system) of involved area; BSC/RNC/MME is transmitted to base station (gsm system is that BTS, UMTS system are NB, and the LTE system is eNB) with it again and is broadcast to the user.
The CBS business of definition is all sent on broadcast channel at present.And broadcast channel does not have any safeguard protection at present.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, can carry out safeguard protection to PWS, promptly, introduce signature algorithm and key managing project through using the method for digital signature field and timestamp.After the alert message of broadcasting is received at the terminal, can at first carry out authentication, only work as authentication success and pass through, be sure of that just it is an effective alert message this message.
For any certificate scheme based on signature, PKI or other that authentication need obtain signer are used for the symmetric key of authentication message, and need guarantee that this key is effective.Promptly for UE, network need send to UE by the key that PWS is professional.For this reason, network needs pre-configured PWS professional key and relevant information.After UE successfully networks, promptly can obtain the PWS key information.When disaster took place, CBC received the warning information that CBE sends over like this, promptly can directly give UE with it through the 3GPP Web broadcast.Simultaneously,, also need send to each network entity by the key information that the PWS that upgrade is professional, send to UE by each network entity again if PWS needs regularly or the professional key of PWS is upgraded in not timing.
In current 3GPP standard, how network entity from the PWS key information to UE that distribute obtains the PWS key information, remains the problem that needs solution.
