Background technology
The topmost feature of group service is to dispatch and to group busy.The scheduling feature of group service is meant that the communication terminal to some makes a call simultaneously, allows these communication terminals converse simultaneously; Grouping busy that function is meant do a simple operations on communication terminal of group service makes a call simultaneously, converses simultaneously all communication terminals in the respective communication group, thereby reach the effect of " getting ready to go into action in hundreds ".Above communication terminal can be wire communication terminal, also can be wireless communication terminal.Group service is widely used in special net user, for example users such as army, railway, public security.Often have the demand that dynamically updates group information in the group service, be mainly reflected in newly-built group, deletion group, dynamically reorganization and distant aspect such as get killed, below in newly-built group, deletion group, dynamically simple declaration is carried out in reorganization and distant operation such as get killed.
For the needs that satisfy certain application are set up a communication group, for example public security bureau needs to set up a special project group for tracking down together criminal case, because each member in the communication group may be distributed in different places, the unified manual data of upgrading each member's communication terminal can be very difficult, therefore can make network side by the technology of eating dishes without rice or wine, group information be write automatically each member's communication terminal.
If certain member in the communication group loses its communication terminal, the situation that non-communication group member listens to the communication group dialogue will appear so, at this moment, network side can be by the remote control means, the technology of promptly eating dishes without rice or wine, this communication terminal is ceased to be in force automatically, and this method is called distant getting killed, and avoids non-communication group member to learn communication group member's activity with this.If need to increase new member in the communication group, network side can carry out group information by the technology of eating dishes without rice or wine and dynamically update, and realizes the reorganization of communication group.If completed successfully task for finishing the communication group that a certain task sets up, this communication group has not had the meaning of existence, then need this communication group is dismissed, network side is deleted group information in each communication terminal by the technology of eating dishes without rice or wine equally, with this communication group deletion.
Fig. 1 dynamically updates the group information flow chart in the prior art, and as shown in Figure 1, the process that dynamically updates group information in the prior art may further comprise the steps:
Step 101～step 102: network side is initiated the group information updating request according to the group information updating needs to communication terminal, requires communication terminal to carry out group information updating; After communication terminal is received the group information updating request, carry out corresponding group information updating operation, return the group information updating response to network side then, the informing network side has been accepted the group information updating request of its initiation.Above-described group information updating request comprises increases group communication terminal request, deletion group communication terminal request, the request of deletion group etc.; Correspondingly, the group information updating response returned to network side of communication terminal comprises increases group communication terminal response, deletion group communication terminal response, the response of deletion group etc.
As seen from the above description, the process that dynamically updates group information of the prior art is directly to carry out group information updating, therefore the group information dynamic updating process of communication terminal is very unsafe, the problem that illegal network malicious modification legitimate correspondence terminal data can occur, the group information that illegal communication terminal response network side also can occur simultaneously dynamically updates, and makes network side think that the legitimate correspondence terminal successfully upgraded group information.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Among the present invention, before network side dynamically updates group information, increase network side communication terminal side is carried out the process of authentication, if communication terminal side is by the authentication of network side, judge that then communication terminal is legal, network side is determined communication terminal side is carried out group information updating; At this moment, communication terminal side is carried out authentication to network side, if network side passes through authentication, then the decision network side is a legitimate network, and communication terminal side is carried out corresponding group information updating, otherwise, communication terminal decision network side is non-method network, does not carry out group information updating.If communication terminal side not by the authentication of network side, judges that then communication terminal is illegal, network side is abandoned the group information updating to communication terminal.
Fig. 2 dynamically updates the group information flow chart among the present invention, and as shown in Figure 2, the process that dynamically updates group information among the present invention may further comprise the steps:
Step 201: network side is according to the group information updating needs, at first initiate authentication request to communication terminal, carry the parameter relevant in this authentication request with authentication, for example, the random number that is used for authentication that network side generates at random and the sign of communication terminal self are as IMSI International Mobile Subscriber Identity (IMSI) or Electronic Serial Number (ESN) or mobile identification number (MIN) or travelling carriage number book number (MDN).Network side is according to the authentication arithmetic of making an appointment with communication terminal, and for example cellular authentication and voice security algorithm (CAVE) calculate authentication information to authentication parameter and communication terminal private cipher key.Above-described communication terminal private cipher key is stored in communication terminal and network side in advance, and the private cipher key of different communication terminal room is different.
Step 202: after communication terminal was received authentication request, according to the authentication arithmetic of making an appointment with network side, for example the CAVE algorithm calculated authentication information to authentication parameter and communication terminal private cipher key, then authentication information is sent to network side.After network side is received authentication information, authentication information of receiving and the authentication information that self calculates are compared, if consistent, then network side judges that communication terminal is legal, and execution in step 203 then; Otherwise network side judges that communication terminal is illegal, abandons communication terminal is carried out group information updating.
Step 203: network side is initiated the group information updating request to communication terminal, carries the parameter relevant with group information updating in this group information updating request, and for example group identification etc. requires communication terminal to carry out group information updating.
Step 204: after communication terminal is received the group information updating request, initiation is to the authentication request of network side, this authentication request carries the parameter relevant with authentication, for example, the random number that is used for authentication that communication terminal generates at random and the sign of communication terminal self are as IMSI or ESN or MIN or MDN.Communication terminal is according to the authentication arithmetic of making an appointment with network side, and for example the CAVE algorithm calculates authentication information to authentication parameter and communication terminal private cipher key.
Step 205: after network side was received authentication request, according to the authentication arithmetic of making an appointment with communication terminal, for example the CAVE algorithm calculated authentication information to authentication parameter and communication terminal private cipher key, then authentication information is sent to communication terminal.After communication terminal is received authentication information, authentication information of receiving and the authentication information that self calculates are compared, if consistent, then communication terminal decision network side is a legitimate network, and execution in step 206 then; Otherwise, the illegal network of communication terminal decision network side, group information updating is not carried out in the group information updating request of refusal network side.After the group information updating request of communication terminal refusal network side, can send the group information updating failure response to network side, the informing network side is not accepted the group information updating request of its initiation.This group information updating failure response can further carry cause value, and is illegal as network side.
Step 206: communication terminal carries out corresponding group information updating operation according to the group information updating request, returns the group information updating response to network side then, and the informing network side has been accepted the group information updating request of its initiation.
Above-described group information updating request comprises increases the group communication terminal request, delete the group communication terminal request, dynamic reorganization is asked, group revises asks, newly-built group asks, deletion group asks etc.; Correspondingly, the group information updating response returned to network side of communication terminal comprises that increasing group communication terminal response, deletion group communication terminal response, dynamically reorganization response, group revises response, the response of newly-built group, the response of deletion group etc.Operations such as group are revised and to be meant the priority of revising group, set up in group.
Fig. 3 is an embodiment schematic diagram among the present invention, and as shown in Figure 3, present embodiment is an example with code division multiple access (CDMA) communication network, and the process that dynamically updates group information among this embodiment may further comprise the steps:
Step 301: network side is according to the group information updating needs, at first send authentication request message (MS_AUTH_REQ) to communication terminal, carry authentication parameter in this authentication request message, for example, the random number that is used for authentication that network side generates at random, the IMSI of this communication terminal.Network side is according to the authentication arithmetic of making an appointment with communication terminal, and for example the CAVE algorithm calculates authentication information to authentication parameter and communication terminal private cipher key.
Step 302: after communication terminal is received authentication request message, according to the authentication arithmetic of making an appointment with network side, CAVE algorithm for example, authentication parameter and communication terminal private cipher key are calculated authentication information, and the authentication response message (MS_AUTH_RSP) that will carry authentication information then sends to network side.After network side is received authentication response message, authentication information of receiving and the authentication information that self calculates are compared, if consistent, then network side judges that communication terminal is legal, and execution in step 303 then; Otherwise network side judges that communication terminal is illegal, abandons communication terminal is carried out group information updating.
Step 303: network side sends to communication terminal increases group communication terminal request message (G_DATA_ADD_REQ), carry and the relevant parameter of newly-increased group communication terminal in this increase group communication terminal request message, for example, the sign of group identification, newly-increased group communication terminal, group's priority parameters, group's encryption parameter etc.Described group priority parameters can comprise the priority and the newly-increased priority of group communication terminal in group of group.
Step 304: after communication terminal is received and increased group communication terminal request message, send authentication request message (NSS_AUTH_REQ) to network side, this authentication request message carries authentication parameter, the random number that is used for authentication that for example communication terminal generates at random, the IMSI of this communication terminal.Communication terminal is according to the authentication arithmetic of making an appointment with network side, and for example the CAVE algorithm calculates authentication information to authentication parameter and communication terminal private cipher key.
Step 305: after network side is received authentication request message, according to the authentication arithmetic of making an appointment with communication terminal, CAVE algorithm for example, authentication parameter and communication terminal private cipher key are calculated authentication information, and the authentication response message (NSS_AUTH_RSP) that will carry authentication information then sends to communication terminal.After communication terminal is received authentication response message, authentication information of receiving and the authentication information that self calculates are compared, if consistent, then communication terminal decision network side is a legitimate network, and execution in step 306 then; Otherwise communication terminal decision network side is illegal network, and sending to network side increases group communication terminal failure response, and the informing network side is not accepted the increase group communication terminal request of its initiation.This group information updating failure response can further carry the illegal cause value of network side.
Step 306: communication terminal is according to increasing the group communication terminal request, in the group of its storage, increase corresponding communication terminal, returning to network side then increases group communication terminal response message (G_DATA_ADD_RSP), and the informing network side has been accepted the increase group communication terminal request of its initiation.
Above-described communication terminal can be according to the needs of practical application to the authentication process of network side, only in the group information updating operation of part, carry out, for example, only communication terminal carries out authentication to network side in increasing the group communication terminal procedures, or only in group's modification process communication terminal network side is carried out authentication, or communication terminal carries out authentication to network side in increasing group communication terminal and dynamic regrouping process, or the like.
Above process is that to carry out group information updating with network side and a communication terminal be example, if network side dynamically updates the group information of a plurality of communication terminals in the group, then can simultaneously or carry out above-mentioned group information dynamic updating process successively between network side and a plurality of terminal.If one of them communication terminal does not pass through authentication in the group service group, then network side is abandoned this communication terminal is carried out group information updating, continuation is carried out authentication to other communication terminals in this group, and network side carries out group information updating to the communication terminal by authentication then.
In a word, the above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
