Ball GSM), UMTS (Universal MobileTelecommunications System, universal mobile communications system
System) and LTE (Long TermEvolution, Long Term Evolution) support PWS business, and provide that PWS business uses CBS
(CellBroadcast Service, cell broadcaste service) carries transmission.Its framework as shown in figure 1, the function of each network element such as
Lower explanation：
Cell Broadcast Entity (Cell Broadcast Entity, abbreviation CBE)：It is not belonging to the communication network that 3GPP is defined.
CBE is responsible for being formatted CBS (Cell Broadcast Service, cell broadcaste service), including CBS message is divided
To the different pages；
CBC (Cell Broadcast Center, abbreviation CBC)：Belong to a part for core network, can be with
It is connected with multiple CBE.CBC is responsible for the management of CBS message, including：Determine that CBS message starts the time of broadcast；Determine CBS message
The time 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 that CBS message is repeatedly broadcast
Interval；It is determined that CBCH of broadcast CBS message etc..For GSM network, CBC is with being located at Radio Access Network
BSC is connected, and interface is IuBC；For UMTS system, CBC passes through IuBC interfaces and the RNC phases positioned at Radio Access Network
Even；For LTE system, (Mobility Management Entity, mobile management is real by the MME of CBC and core net
Body) it is connected, interface is S1BC.After CBC is configured and encapsulated to the CBE received the alert messages sent, it is sent to by shadow
BSC (gsm system), the RNC (UMTS system) and MME (LTE system), BSC/RNC/MME for ringing region forward it to each system again
(gsm system is that BTS (BaseTransceiver Station, base transceiver station), UMTS system are NodeB (sections for the base station of system
Point B), LTE system is eNB (enode b)), by base station broadcast to user.
The CBS business defined at present is sent over the broadcast.And broadcast channel is without any safeguard protection at present
Measure.Attacker can distort alert message, or receive after alert message, be weighed in another impregnable area
Put, so as to cause unnecessary panic and confusion in the public.
In order to prevent the appearance of such case, 3GPP determines to carry out safeguard protection to PWS, i.e., by using digital signature word
The method of section and timestamp, introduces signature algorithm and key managing project.Terminal is received after broadcasting alarm notifications, can be first to this
Alert message is authenticated, only after certification is successfully passed, and it is an effective alert message just to firmly believe it.
For any certificate scheme based on signature, authentication is required to obtain the key of signer, i.e., for UE,
Need the key of acquisition signer.Because the key is usually a public key, therefore network is in order to ensure the freshness and peace of key
Full property for each key, it is necessary to set an effective life cycle.In the life cycle, the key can normally be made
With；Before the key expires, network needs to be updated the key, and successfully enables new key, to ensure that the key is
Effectively.But in current 3GPP specifications, still do not defined to how PWS keys are updated.

The next PWS keys used；
8) MME is according to the key updating message received, updates next PWS keys used for locally preserving and current
The PWS keys used, and send key updating response message to CBC；
2) MME judges that the currently used PWS keys received are identical with what is locally preserved, without updating, newly receives
Next PWS keys are different from the next PWS keys used locally preserved, then using the next PWS keys received
Substitute the next PWS keys used locally preserved；
3) UE sends TAU request messages to MME；
4) MME sends to UE and current key id and next keyid is carried in TAU response messages, message；
5) UE is received after TAU response messages, by being contrasted with the key id locally preserved, judges next key id more
It is new, it is all different from what is locally preserved.Now UE abandons next key, retains currentkey.And please in TAU processes next time
The next key looked for novelty；
6) UE indicates that network increases nextkey parameters in the response in normal TAU request messages next time.The TAU
Next key requests are carried in request message and indicate parameter；
7) MME sends TAU response messages to UE, and message carries next key keys, including nextkey and next key
id；
