Standby and terminal.
Background technology
In order to enable users to timely and accurately receive the alarm on disaster and other emergencies, warning and crucial letter
Breath, 3GPP (3rd Generation Partnership Project, third generation partner program) define PWS
(Public Warning System, public warning system) business.Meet with such as earthquake, tsunami, hurricane and outdoor fire disaster
During disaster, the business can enable the public to take suitable action to avoid oneself and its household severely injured or dead, or by
The heavy losses of property.
The different communication network that 3GPP is defined, as GSM (Global System of Mobile communication, entirely
Ball GSM), UMTS (Universal Mobile Telecommunications System, universal mobile communications
System) and LTE (Long Term Evolution, Long Term Evolution) support PWS business, and provide that PWS business uses CBS
(Cell Broadcast Service, cell broadcaste service) sends to carry.Its framework is as shown in figure 1, the function of each network element
It is as described below：
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 are 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 BTS (Base Transceiver Station, base transceiver station), UMTS system is 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 after receiving alert message, weight is carried out in another impregnable area
Put, it is unnecessary panic and chaotic so as to be caused 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, introduce signature algorithm and key managing project., can be first to this after terminal receives broadcasting alarm notifications
Alert message is authenticated, and only after certification successfully passes, it is an effective alert message just to firmly believe it.
In order that security intensity reaches certain rank, that is, it is not easy to be broken through by attacker, 3GPP SA3 working groups are recognized at present
Need to take 56 bytes for proper security information.If information safe to use is less than the algorithm of 56 bytes, such as 40 words
The algorithm of section, attacker can be easier to break through, and not reach expected protecting effect.RRC (the Radio and 3GPP eats dishes without rice or wine
Resource Control, wireless heterogeneous networks) agreement to security information reserve maximum length be 43 bytes, it is impossible to meet peace

Below with reference to the accompanying drawings and connected applications example, to describe the present invention in detail.
Using example 1
This shows the pre-configured flows for receiving all segmentations and recombinating again in terminal using example, as shown in Fig. 2 specifically
Including：
1) the pre-configured restructuring strategy in terminal, i.e.,：All segmentations recombinate together after all receiving, and then judge to recombinate again
The legal integrality of the information obtained afterwards；
2) when network side there are the main advertised informations of the PWS to be issued, according to pre-set length, the PWS master is led to
Information is accused to be segmented.Then each segmentation will be handed down to terminal successively；In actual segment, typically by the main advertised informations of PES
Being divided into two segmentations can meet demand.
Wherein, the length of security information no more than eats dishes without rice or wine RRC agreements as the reserved maximum of security information in each segmentation
Length, such as 40 bytes.
3) according to pre-configured strategy, terminal after all segmentations are received, recombinate these be segmented and verify restructuring after
The legal integrality of information.
If the information after restructuring is legal complete, then the protocol layer of terminal sends the main notices of the PWS to interface and disappeared
The content of breath.
Using example 2
This shows the pre-configured flow for often receiving a segmentation and recombinating in terminal using example, as shown in Figure 3.
In this case, end side needs to know that network side is (length for predicting each segmentation) how to be segmented, and such terminal is
Preliminary checking can be carried out according to the partial segments received.Idiographic flow includes：
1) the pre-configured restructuring strategy in terminal, i.e.,：Often receive a segmentation just to recombinate, after judging restructuring immediately after
The legal integrality of obtained information.
2) when network has the main advertised informations of the PWS to be issued, according to pre-set length, to the main notices of the PWS
Information is segmented.Then each segmentation will be handed down to terminal successively；In actual segment, typically by PES main advertised informations point
Can meet demand for two segmentations.
Wherein, the length of security information no more than eats dishes without rice or wine RRC agreements as the reserved maximum of security information in each segmentation
Length, such as 40 bytes.
3) according to pre-configured strategy, after terminal often receives a segmentation, verify by current paid-in all segmentation weights
The legal integrality of the information (being probably partial information, it is also possible to complete information) obtained after group.
The method of checking includes but is not limited in the following way：Terminal extracts responding from first segmentation received
Message is reported, and the main advertised informations of PWS are calculated according to the alert message；Then, from the main advertised informations of PWS that this is calculated
First bit starts, and takes out the information of the information same word joint number with being obtained after the restructuring, and relatively whether the two is identical, if phase
Together, then it is legal complete to judge the information obtained after the restructuring；Otherwise, it is determined that the information obtained after restructuring is illegal complete
's.
This is a kind of verification method for accumulating superposition, and with the increase for receiving division number, the accuracy of checking progressively increases
Add.Until receiving all segmentations, the result of checking is right-on.
If first segmentation is legal complete, then the protocol layer of terminal sends the main notice messages of the PWS to interface
Content.And after other subsequently received segmentations, if it is decided that the information after restructuring is legal complete, then no longer needs to lead to
Interface is known, because having notified interface when first segmentation is verified；And if in other subsequently received segmentations
Afterwards, if it is decided that the information after restructuring is not legal complete, and at this moment the protocol layer of terminal needs to send new information to interface,
Message with hair before indicating interface is mistake, it is necessary to abandon.
Using example 3
This application example assumes that the segmentation to the main advertised informations of PWS only has two sections, because actually general two sections can expire
Sufficient demand.If three sections or more, method is identical.
This shows the SI cycles that terminal configures according to network side using example, when receiving two maximums being segmented to calculate
Between whether the maximum time 4s issued more than the main advertised informations of PWS.In the case that what this application example provided is no more than 4s,
The flow recombinated again after all segmentations is received, as shown in figure 4, specifically including：
1) the lateral terminal configuration SI cycle informations of network；
2) the SI cycles that terminal configures according to network side, to estimate the maximum time for receiving two segmentations whether more than PWS
The maximum time 4s issued.If being no more than 4s, decision is recombinated again after receiving all segmentations；
3) network issues first segmentation to terminal；
4) network issues second segmentation to terminal；
5) terminal is after all segmentations are received, and recombinates these and is segmented and verifies the legal complete of the information that is obtained after restructuring
Property.
If it is legal complete to verify the information obtained after the restructuring, then the protocol layer of terminal is sent to interface to be had
The content of the main notice messages of PWS of body.
Using example 4
This application example assumes that the segmentation to the main advertised informations of PWS only has two sections, because actually general two sections can expire
Sufficient demand.If three sections or more, method is identical.
This shows the SI cycles that terminal configures according to network side using example, when receiving two maximums being segmented to calculate
Between whether the maximum time 4s issued more than the main advertised informations of PWS.What this application example provided be more than 4s in the case of, often receive
It is the flow of recombination checking to a segmentation, as shown in figure 5, specifically including：
1) the lateral terminal configuration SI cycle informations of network；
2) the SI cycles that terminal configures according to network side, to estimate the maximum time for receiving two segmentations whether more than PWS
The maximum time 4s issued.If it exceeds 4s, decision often receives a segmentation and carries out a recombination checking；
3) network issues first segmentation to terminal；
4) terminal directly verifies the legal integrality of the information according to first segmentation received；
If the segmentation is legal complete, then the protocol layer of terminal sends the specific main notice messages of PWS to interface
Content.
5) network issues second segmentation to terminal；
6) after terminal receives second segmentation, the segmentation and first segmentation are recombinated, and again after checking restructuring
The legal integrality of obtained information；
This is a kind of verification method for accumulating superposition, and with the increase for receiving division number, the Exact Travelling of checking progressively increases
Add.Until receiving all segmentations, the result of checking is right-on.
7) if it is illegal complete to verify the information obtained after the restructuring, then the protocol layer of terminal is sent out to interface
Fresh information is sent, the notice before indicating is mistake, it is necessary to carry out discard processing.If verify the letter obtained after the restructuring
Breath is legal complete, then is not longer notified about interface.
