Abstract
The present invention relates to a temporary cluster conversation requesting method which comprises the following steps: an initiator is required to transmit a conversation requesting message of URI containing all called subscribers to a PoC server of a called subscriber; the PoC server of the called subscriber inquires black and white lists of the called subscriber; the PoC server of the called subscriber compares the inquired black and white lists of the called subscriber and the URI of other called subscribers to obtain the called subscribers in all temporary clusters in the black and white lists of the called subscriber; the PoC server of the called subscriber makes the result contained in the connection requesting message to send the result to the called subscriber. The temporary cluster conversation requesting method of the present invention makes the called subscriber know whether users in the own black and white lists are invited, and consequently, whether joining the conversion or not is decided, and the called subscriber can not receive the information of the users out of the own black and white lists, and thereby, the problem that the privacy is exposed is avoided. Moreover, the troublesome operation does not needed to be added by a calling subscriber and the called subscriber, the time for establishing the conversation is shorter and the network flow is small.
Description
Technical field
(Push to Talk over Cellular, PoC) business relates in particular to a kind of conversation request method that is applied in the interim group in the PoC service to the present invention relates to Push to talk over Cellular.
Background technology
PoC service is a kind of based on the mobile cellular public network, and networks such as GPRS, cdma2000, WCDMA or cdma2000 for example adopt the half duplex communication system of voip technology, and it has used the PTT in the group system (Push-to-Talk, pushes to talk) characteristic.The PTT business also claims push-to-talk service, and it can support " point-to-point " and " putting multiple spot " Speech Communication, and the promoter of session can tabulate to the group and initiate conversation by ID of group or caller.
Group in the PoC service can be divided into two classes: a class group is the group that has set up before initiating a session request, the information of this group is kept at XDM (XML Document Management, the extend markup language data management) in the server, being provided with the back initiation session uses, in this case, initiation session people initiates a session request by the ID of group, and the PoC server is received request back extraction group list, the member in the invite group then from the XDM server; Another kind of group is interim group, the group that promptly before initiating a session request, does not have foundation, initiation session people files a request to the PoC server by the form that adds the tabulation wait to invite the people in conversation request message, the PoC server receives that the request back parses the list of waiting to invite the people from the tabulation of request message, send conversation request to people to be invited then.
In the PoC service, the access strategy that also has the user, it is black and white lists, the user is by being provided with blacklist (reject list), the terminating call barred of people in the blacklist can be fallen, by white list (accept list) is set, the user can come the calling of the people in automatic-answering back device or the manual answering white list in conjunction with the answer-mode of oneself; Whether the not calling of the people in black and white lists needs called subscriber's manual confirmation to reply.The tabulation of called subscriber's black and white lists is kept in the XDM server in PoC service, participating in function server (ParticipatingFunction Server, PF Server) receives controlled function server (Controlling Function Server, CFServer) after the conversation request, participating in to check and to carry out user's access strategy when function server issues this request to the called subscriber.
In the PoC service, also support user's privacy, promptly the user can specify oneself whether to hide number when participating in session, adopts anonymous mode to insert session.At present when setting up group or the user when adding PoC session, usually specify the own pet name in session, by hiding the mode of the number and the pet name, prevented that preferably user URI (Uniform Resource Identifier, unified resource identifier) from leaking the problem of giving other members in the group.
Because when sending interim cluster conversation, the called subscriber does not also insert, and interim group do not have information and deposit in the database before calling, so called subscriber's the pet name is unavailable.When initiating interim cluster conversation, can only adopt the form of called URI tabulation to make a call.Called for one, perhaps, whom has been invited is the reference that the called subscriber determines whether to add session, therefore the called subscriber has the demand that obtains all called subscriber's identity informations, if all called subscribers' URI is given called, the problem that the called subscriber URI that then can cause some to be reluctant to reveal URI is leaked.
The conversation request of at present interim group has four kinds of modes:
The one, the calling subscriber issues the PoC server with the invitation of the conversation request of interim group, and the PoC server does not provide any other called subscriber's information when each called subscriber initiates to invite.This mode causes the called subscriber can't know which user has been invited, and therefore lacks whether necessary reference accepts this interim group with decision conversation request.
The 2nd, the calling subscriber issues the PoC server with the invitation of the conversation request of interim group, and the PoC server provides every other called subscriber's information when each called subscriber initiates to invite.This mode then can cause because the called subscriber may be a lot, so network traffics are big, leaked part called subscriber's URI in addition, therefore have the privacy compromise problem.
The 3rd, when the calling subscriber issues the PoC server with the invitation of the conversation request of interim group, specify which called subscriber's identity information to be hidden, the PoC server is when each called subscriber initiates to invite, the calling subscriber is specified the called subscriber's who hides identity Information hiding, the information that every other called subscriber is provided is to the called subscriber, and the called subscriber that hide identity is shown as hiding.This mode can cause the calling subscriber to be difficult to know that the understanding between the called subscriber concerns, even under the situation of understanding, also has the situation of not knowing the other side URI between the called subscriber of understanding, has the danger of potential leakage privacy of user; The calling subscriber specifies the called subscriber whether to hide identity before calling in addition, and is cumbersome; And network traffics are big.
The 4th, when the calling subscriber issues the PoC server with the invitation of the conversation request of interim group, the PoC server sends not conversation request with any called user information to the called subscriber, the called subscriber is receiving the request back has added session (after other called subscribers' addings to which user of PoC server requests, there has not been privacy concern), after the PoC server acknowledge, this called subscriber determines whether add again.Signaling process complexity when this mode can cause session to be set up, setting up session needs the long period, and only obtains the called subscriber's of current participation session information, and reference significance may not be very big, particularly the session initial stage.
Summary of the invention
Technical problem to be solved by this invention is to provide which user in the black and white lists that a kind of called subscriber can know oneself to be invited to add interim cluster conversation, and can not reveal the conversation request method of interim group of own black and white lists user's in addition privacy.
