Description
Communication means and system in user network on 04 04th, 2006 this application claims Patent Office of the People's Republic of China, Application No. 200610025438.0, the priority of the Chinese patent application of entitled " communication system and its method of user equipment in user network " was submitted, and entire contents are hereby incorporated by reference in the application.Technical field
The present invention relates to the communications field, the more particularly to communication technology in user network between user equipment.Background technology
In recent years, increase with the development and people of science and technology to high-tech product demand, ancillary equipment that people are possessed gradually increases, users are not only possible while possessing multiple laptop computers, mobile phone etc., it it may also be desirable to connect the ancillary equipment such as printer, scanner, modem on the PC of oneself, sometimes USB interface is also plugged, the photo in digital camera is transmitted and stored into hard disk.Continually the various cables being wrapped after a certain interface, PC are extracted in insertion, are all made user while experience new technology brings enjoyment, are had to stand some inconvenience.In addition, mobile of the information transmission between enterprises each department personnel also to information transmission in modern enterprise proposes higher requirement, in limited working environment, composition LAN can realize information sharing and collaborative share（Printer, scanner etc.）, but thickly dotted wiring gives people to make troubles again.For this phenomenon, academia proposes a new concept：Individual domain network（Personal Area Network, cylinder claims " PAN,）.PAN Wang Network are exactly in the space that a radius of action is smaller, type of service is abundant, towards special group, to realize the mobile radio communication of wireless connection.This is a kind of and wide area network, the LAN still less wireless network of scope arranged side by side.
The core concept of PAN networks is that traditional wire cable is replaced with radio or infrared ray, realizes the intelligent interconnection of personal information terminal, sets up personalized Xin Xi Wang Network.From the perspective of computer network, PAN networks are a LANs；From the perspective of communication network, PAN networks are an access networks, therefore someone calls PAN networks the solution of communication network " last rice ".Application scenario of the PAN network positions in family and small office.Its main application includes：Speech Communication gateway, data communication gateway, information appliance interconnection are exchanged automatically with information.
PAN networks realize that technology mainly has：Bluetooth（Bluetooth), Infrared Data Association（Infrared Data Association, cylinder claims " IRDA ") infrared communication technology etc..
Can be with blunt all user equipmenies (User Equipment well to same user closely by PAN networks, referred to as " UE ") it is managed and is exchanged with information, but PAN network range is smaller after all, such as the stronger UE of mobile phone mobility can not possibly be limited in a PAN network, user is managed to its own all UE for convenience, Network is netted in the UE compositions family for belonging to same user by us, and the user network can include physically phase ^ [blunt far more UE or the PAN networks being made up of UE.
In the prior art, the communication bag between each UE in same Yong Hu Wang Network is containing two kinds of situations, one, it is that the UE both sides communicated are in together in the same PAN networks of same user network, that is UE both sides' short-range communication, in this case, wireless technical approach can be used, such as use bluetooth, infrared communication wireless technology, or use wired technical approach, as using the cable technology including USB cables, the point-to-point communication of UE both sides directly carried out, without the management by carrier network.That is, the UE both sides of communication need not move through core net, only in PAN network internals by closely connecting direct communication, as shown in figure 1, being this kind of communication mode between UE1 and UE2.
Secondly, for not under same access network, UE1 and UE3 in UE i.e. not in same PAN networks, such as Fig. 1, due to needing telecommunication, therefore the communication between them needs the switching centre provided via operator to swap, that is, when UE1 needs to be communicated with UE2, being initiated to ask by its access network A by UE1, then pass through switching centre and access network B, get to UE3.In addition to some control signalings, UE1 data transfer is needed also exist for successively by access network A, switching centre and access network B, can just be transferred to UE3.
In actual applications, the security communicated using such scheme in same user network between each UE can not be guaranteed, and the communication between each UE largely occupies switching centre's resource.
Due to using point-to-point communication between the UE in same PAN networks in same user network, that is, the UE both sides communicated need not move through core net, only exist:PAN network internals are directly set up connection and communicated, in the absence of any safety certification measure, so as to can not ensure the security of communication.And when the UE communicated in same user network is not in same PAN networks, communicating pair must could be communicated by switching centre, the ample resources of switching centre is occupied.The content of the invention
The embodiment of the present invention provides the communication system and its method of user equipment in a kind of user network, makes
Safety guarantee can be obtained by obtaining the communication information in user network between UE.
The embodiment of the present invention provides a kind of communication means being used in user network, comprises the following steps：When two user equipmenies for belonging to same user need communication, communication request is sent to the management entity for preserving the user equipment registration information by the first user equipment, and the connection with second user equipment is set up in request；
The management entity carries out safety certification according to the communication request and the log-on message preserved to first, second user equipment；
After certification success, first user equipment directly sets up point-to-point connection with second user equipment.
The embodiment of the present invention provides a kind of user network communication system, and with least two user equipmenies and its access network for belonging to same user, the system includes：
Management entity, for preserving the log-on message of the user equipment and carrying out safety certification to the user equipment；
Communication request is sent to the management entity, the management entity carries out safety certification according to the communication request and the log-on message preserved to first, second user equipment by the first user equipment when needs and second user equipment are set up and communicated；
After certification success, the first user equipment directly sets up point-to-point connection with second user equipment.
In summary, in technical scheme provided in an embodiment of the present invention, two UE in user network are set up before point-to-point connection, are first passed through access network and are asked to management entity to related UE safety certification, only related UE certification all by when just set up point-to-point connection.By increasing the safety certification before connection, it is therefore prevented that illegal UE is unwarranted to UE in user network to be accessed.Management entity can also ensure the safety of data transfer by providing key to the successful UE of certification.
When two UE for belonging to same user need to be communicated, safety certification is carried out to communicating pair by the management entity in the user network, ensure the legitimacy of communicating pair, and pass through in certification rear, further key is provided by management entity for communicating pair so that the security of communicating pair data transfer is protected.
If two UE are not in same people domain network, point-to-point connection is the long-range connection set up by respective access network.Because the point-to-point between two UE is connected without switching centre, institute
So that the resource of switching centre can be saved from when communicating far huge.Brief description of the drawings
Fig. 1 is the schematic diagram that the UE in the prior art in same user network is communicated；Fig. 2 is the communication system architecture figure of UE in user network according to a first embodiment of the present invention；Fig. 3 is the communication system architecture figure of UE in user network according to a second embodiment of the present invention；Fig. 4 is the communication means flow chart of UE in user network according to a third embodiment of the present invention.Embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is described in further detail.
Principle below according to the present invention is illustrated to the communication system of UE in the user network of first embodiment of the invention.
As shown in Fig. 2 UE communication system includes and belongs at least two UE and its access network of same user in user network, and for preserving these UE log-on message and the management entity of safety certification being carried out to it.Wherein, the above-mentioned each UE for belonging to same user is located in same PAN networks, and is interacted by same access network with its management entity.
Specifically, multiple UE of same user are belonged in the system before needing to be communicated, are registered in advance in its management entity, meanwhile, the management entity preserves each UE registered log-on message.Thereafter, when the UE1 of the user needs the UE2 foundation with belonging to the user to communicate, UE1 sends communication request by its common access network A to management entity first, request is communicated with UE2, and UE1 log-on messages in itself and UE2 device id are included in the communication request.Management entity is received after the request, the log-on message just preserved before blunt evidence carries out safety certification to UE1 and UE2, such as, whether UE1 log-on message is consistent with the log-on message preserved in management entity contrast communication request, judge whether the UE1 for initiating communication request is legal, and judge whether UE2 has registered according to UE2 identification number, safety certification is carried out to UE1 and UE2.If certification success, the management entity sends the device id for including UE1 in the request message of communication, request message to UE2.UE2 is received after the request message, decides whether to agree to be communicated with 1, and sends corresponding feedback information to management entity according to the decision.Management entity is judged the feedback information received, if UE2 receives the request communicated with UE1, management entity is further UE1 and UE2 generation temporary keys, and the key is sent respectively into UE1
And UE2, meanwhile, the UE2 confirmation messages for receiving this communication are sent to UE1 by management entity.UEl and UE2 sets up its being directly connected in PAN network ranges after the key is received, and after a connection setup, the temporary key provided by management entity is communicated.
Second embodiment of the invention is roughly the same with first embodiment, as shown in Figure 3, UE communication system includes at least two UE and its access network for belonging to same user in user network in second embodiment, and for preserving these UE log-on message and the management entity of safety certification being carried out to it, it differs only in each Ε for belonging to same user in the system of second embodiment not in same PAN networks, each UE is interacted by respective access network and management entity, and the UE both sides communicated are needed after safety certification success, long-range connection is set up by respective access network.
Such as, same user possesses multiple UE, wherein, UE1 and UE3 be not in same PAN networks, and UE1 is connected with access network A, and UE3 is connected with access network B.When UE1 needs to be communicated with UE3, UE1 to the communication request that is communicated with UE3 of management entity transmission, includes UE1 log-on messages in itself and UE3 device id by access network A in the communication request.Management entity carries out safety certification according to the request message received and the log-on message preserved to UE1 and UE3, if safety certification success, the communication request message of the device id comprising UE1 is sent to Ε 3.UE3 receives the request message from management entity by access network B, decides whether to agree to be communicated with UE1, and sends corresponding feedback information to management entity according to the decision.If management entity receives the feedback information that UE3 agrees to carry out this communication, it is further then UE1 and UE3 generation temporary keys, and the key is sent respectively to UE1 and UE3, meanwhile, the UE2 confirmation messages for receiving this communication are sent to UE1 by management entity.UEl and UE3 sets up long-range connection, and after a connection setup, communicated by the temporary key by access network A and access network B respectively after the key is received.
UE communication means in the user network of third embodiment of the invention, as shown in figure 4, in step 410, UE1 sends the communication request communicated with 2 to management entity when needing to be communicated with belonging to the UE2 of same user.Specifically, belonging to the UE1 and UE2 of same user can be located in same PAN networks, it can also be located in different PAN Wang Network, if UE1 and UE2 is located at same PAN networks, then UE1 sends the communication request communicated with UE2 by its common access network when needs are communicated with UE2 to management entity；If UE1 and UE2 is located in different PAN networks, UE1 passes through the access belonging to it when needs are communicated with UE2
Net sends the communication request communicated with UE2 to management entity.Wherein, UE1 log-on message and UE2 device id are included in communication request.
Step 420 is subsequently entered, management entity is received after the communication request from UE1, safety certification is carried out to UE1 and UE2 according to information therein.
Specifically, each UE needs for belonging to same user are registered in management entity in advance, and management entity also needs to preserve registered UE log-on message.Therefore, after management entity receives the communication request from UE1, safety certification can be carried out to UE1 and UE2 according to the information in the communication request and the log-on message itself preserved.
Step 430 is subsequently entered, whether through safety certification management entity judges UE1 and UE2, if entering step 450 if, whereas if not passing through, then into step 440;
In step 440, management entity returns to this communication request failure to UE1.Due to only the UE both sides for needing to communicate all through safety certification when, management entity just continues this communication request, so as to effectively prevent, illegal UE is unwarranted to UE in user network to be accessed, and has ensured the security of communicating pair.
In step 450, through safety certification, management entity sends the request message of communication to UE2 to UE1 and UE2, pretty to seek the device id that UE1 is included in message.
Step 460 is subsequently entered, UE2 receives the request message from management entity, and decides whether that agreement carries out this communication according to wherein UE1 device id.Equally, if UE1 and UE2 is located at same PAN networks, UE2 receives the request message from management entity by its common access network, and decides whether to agree to carry out this communication；If UE1 and UE2 is located in different PAN Wang Network, UE2 receives the request message from management entity by the access network belonging to it, and decides whether to agree to carry out this communication.If UE2 agrees to carry out this communication, the feedback message for receiving this communication is sent to management entity, into step 480, conversely, then entering step 470;In step 470, UE2 sends the feedback message of this communication of refusal to management entity, and management entity is received after the refuse information, and then notifies UE1 this communication request failures.
In step 480, because UE2 agrees to be communicated with UE1, therefore management entity is this communication generation temporary key, and the temporary key is sent respectively into UE1 and UE2, meanwhile, the UE2 confirmation messages for receiving this communication are sent to UE1 by management entity.Due to the temporary key UE both sides need communicated when produce temporarily, have stronger randomness and real-time, be difficult by
Illegal user is cracked, and communicating pair is communicated by temporary key, has ensured the security of data transfer in communication process.
Step 490 is subsequently entered, UE1 and UE2 set up point-to-point connection and communicated after the temporary key is received.Specifically, if UE1 and UE2 is in same PAN networks, UE both sides set up being directly connected in its PAN network range, and after a connection setup, the temporary key provided by management entity is communicated；If UE1 and UE2 are not in same PAN networks, UE1 and UE2 set up long-range connection by its respective access network respectively, and equally after a connection setup, are communicated by the temporary key.
Because when carrying out telecommunication, the UE both sides of communication no longer need, by switching centre, largely to have saved the resource of switching centre, enable its resource more reasonably to be utilized.
Although by referring to some of the preferred embodiment of the invention, the present invention is shown and described, but it will be understood by those skilled in the art that can to it, various changes can be made and equivalent substitution in the form and details, without departing from the spirit and scope of the present invention.
