Connect the server to the second mobile terminal. To achieve the above objective, the present invention provides a mobile content sharing and delivery system in an integrated network environment, which includes a first-action terminal to transmit information to the Internet; a court server n's temporary storage or And storing at least one receiving end of the information to establish a connection between the first mobile terminal and the receiving end; and at least one second mobile terminal as the receiving end receiving the data transmitted by the home server. The present invention further provides a method for secure transmission in an integrated network environment, which is a mechanism required to be connected between a first-action terminal, a family ship H, and at least a second action terminal, including a publication (4): The family ship-supply-transmission period is transmitted to the first action & and the first-action terminal; the first-action terminal and the home-feeding device pre-generate the k-supplier, and the second mobile terminal starts to download; And the home feeding device is self-satisfied after the start of the transmission transaction - the transaction is linked to the connection between the family and the second line. The details of the present invention are more easily understood by the detailed description of the specific embodiment. Technical content, features, and effects achieved by the present invention. [Embodiment] The present invention provides a mobile content sharing and transmission system and method thereof in an integrated network environment, and the first figure shows the action content in the integrated network environment according to the present invention. The block diagram of the sharing and delivery system 201038032 includes a first mobile terminal 10 for transmitting information to a home server 12 on the Internet, and the 12th serving device temporarily stores or stores the information of the first mobile terminal. And searching for at least one of the information as the second mobile terminal 14 of the receiving end to establish a connection between the first mobile terminal 1 and the first mobile terminal 14, so that the second mobile terminal 14 can receive through the home feeding device I? Information to the first mobile terminal 10. ° The first mobile terminal 10 and the second mobile terminal 14 use the address layer, the search layer (Discovery 丨ayer), and the description layer (Descrjpti〇) in the plug and play protocol. n 丨ayer) and a control layer, wherein the addressing layer obtains a network address of each of the first mobile terminal ι and the second mobile terminal 14 when the first mobile terminal 1 and the second mobile terminal 14 When joining the network, the addressing layer is addressed by a dynamic host configuration protocol (Dynam|c H〇st Configuration Protocol, DHCP) or an automatic 丨p mode, which is used when the dynamic host configuration protocol does not exist; A mobile terminal searches for the second mobile terminal 14 using a search layer using a simple service search protocol (S_e Serv|ce D|sc〇very pr〇t〇c〇|, SSDP) in a small area network. The first mobile terminal 10 and the second mobile terminal 14 are periodically scheduled in advance. The position of the righteousness broadcasts and uses the broadcast-message to indicate the access location of the description file of the first-action terminal 1Q and the second action-end 14 through the description layer; the control layer side-fresh object access protocol (Sim yesterday Object Access) P "otocol, S0AP" is customized, and the Ηπρ and xml technologies are integrated to provide the Web service based information. The control layer can provide the first action terminal 1Q and the second action terminal 14 _ material exchange and content sharing browsing.- ——, currently plug-in (four) organization has standardized __ some (four) device communication format to ensure that the same type of devices from different manufacturers can communicate normally, but the action content The transmitted heart H has been derogated. For this reason, the architecture design of the present invention is customized at the present stage by the control layer - a simple communication format to meet the basic meta data exchange and sharing content browsing requirements. . In addition, although the message standard of the Simple Object Access Agreement is based on a reliable network or a small __ Road towel, there is a very good effect. The package information transmitted by Renren is too large, which will cause additional computer operations 201038032 1 Bear. These situations make the simple object access protocol not turn over in an unreliable wireless network environment' and long-distance transmission. Therefore, the present invention will implement the control of the leak-proof device in the mobile terminal device. On the home server, another set of remote transmission mechanism similar to the Remote Procedure Call Protocol (RPC) architecture, in the wide-area _ medium mobile device and home value Communicate with each other. Ο—Unsynchronized data transmission part, this issue _ counts three basic data download services and internal recording services, in which the content directory service considers the mobile broadcast system of the mobile handheld device simple 'this service is designed to establish the first - mobile terminal And the virtual broadcast system of the second action end, on the 'and according to the user's request to show the shared content, all the shared items j corresponding to the _ _ (meta_data), for example: virtual age can create audio films, etc. Categories.

Z: The device stores three files of 1, 2, and 3 in the device, and two files of 1, 2, 3, 4, and 5 are stored in the second file. The first action terminal 伺 = servo: device 12 asks for a file to share the file 'through °: seeking j private comparison, the first - action terminal 10 decides to guide the download list - the binding terminal 14 requires it to change from the family ship 12 Download; this is clear. Case 1 is sent directly by the first-action 1G, although there are also the first and the first end. However, the second mobile terminal 14 may be required to download the 2, 3, 4, 5 files through the different network, and the home server 12 end of the 201038032 terminal 10. (3) Continued transmission service: Due to the situation that the content sharing process may encounter disconnection and reconnection, etc. 'This service is designed to allow the second mobile terminal to continue the transmission service before the transmission deadline has expired, as long as the second mobile terminal Still retaining the slot location table on the other's home feeding device, the unfinished downloading operation can be continued. The system architecture of the present invention uses a secure transmission mode with authorization and verification mechanisms, as shown in the fourth figure. When the first mobile terminal 1 asks to initiate a redirect download, a secure transfer transaction is initiated and the home server 12 is responsible for managing the transaction process and status. The process of this transaction will be specified - a transaction period; the pure limit means the entire transmission transaction process, including: starting from the first-action terminal 1 notification of the home server 12 and the second mobile terminal 14, the first The second mobile terminal 14 can re-download the download until the desired item is downloaded, unless any of the following occurs: the second mobile terminal 14 terminates the transmission request, the transmission transaction period ends, or the interval between the two downloads exceeds a certain time. The set value ensures that the resources on the home server 12 and the connected network resources are effectively used. In addition, in the transaction process, in order to ensure that the home server 12 can believe that the second mobile terminal 14 is a trustworthy person, the present invention further designs a simple symmetric double gold mine protection mechanism, and the use of the gold balance includes the following two: (1) Provider Key (P-Key): It is pre-generated by the home server 12 and the first mobile terminal 10 to ensure a trust relationship between the two. The provider key is used at intervals. Will be updated 'to avoid the possibility of being cracked after repeated use; (2) Transaction Key (T-Key): It is a temporary, useful period of the key 'When a transaction opens Automatically generated by the home server 12, valid only during the transaction, to protect the short transaction identity between the second mobile terminal 14 and the home server 12 and is not known by the second mobile terminal 14. Once the transaction is completed, it will expire immediately to avoid the possibility that the transaction record may be arbitrarily signed by the unauthorised user; when the mother has a redirected download, the first terminal 10 will send to the home server 12 Request 201038032 The new transaction key, this key transaction will not be the end of the second act 14 know, and immediately expire after the end of the transfer transaction, so as not to be imitated. In the system architecture of the present invention, data is transmitted between the first mobile terminal, the home server, and the second mobile terminal in an XML-RPC mode, and the two-field data is used to confirm the remote program call protocol (Rem). 〇te pr〇cedure ca丨丨, RPC) The identity of the home server and the receiving end (ie the second mobile terminal) and the authorization status. Each RPC request contains the identity authentication information of the RPC transmitter (ie, the first mobile terminal) to confirm whether the transmitter is trusted or has sufficient authority to perform the specified action. Even this requirement must include a set of verification codes to prevent the data from being arbitrarily falsified, and to perform non-original actions. The RPC family feeding service can compare the verification code with the verification code calculated by itself. The following is the representation format of the sum: Identifier := #{P-Key} | (#{P-Key} &#{T-Key})

Since the provider Jin Yu and the transaction key are unique in the transaction, the RPC home server can use the value check to determine whether the sender of the message is trustworthy. 0 The home server is designed with a virtual file system, which is above the native file system. 'But it does not need to reflect the directory structure of the native file system. The directory structure of the virtual file system can be the slot defined by the user. Directory name, each file and directory has a meta-data description as described in the third figure, plus some management purpose information, including Global Resource Locator (URL). The URL) block is specially defined with two types: real and virtual. The relative position of the real url file in the native file system, such as 1^1_:=/?1_8356/eight\/_01"/内灿阳/1\^ Button 69, and virtual 111^1_ is a temporary file location reference, dynamically generated by the name corresponding service, such as URL:= /URLBase/PicXXX.jpeg; virtual file system will transfer it to 201038032 after obtaining virtual URL Back to the real URL representation. The virtual URL is a meaningless string generated dynamically by the group. For each transaction, it is required to share the hard-to-reach ride to establish an access point, and store the virtual correspondence so that the second action end is transparent. Temporary access points require storage until the transaction is closed, and all corresponding and temporary access transfers generated during the process are automatically destroyed. Therefore, the virtual file system and dynamic name mapping mechanism provide a simple and secure content. The directory service 1 state name corresponds to Lai's method to enhance security without causing additional burden. When the client obtains the virtual URL, the file can still be downloaded through the Ηπρ certificate method. In summary, in order to release the local area network The mobile limit, the integration of the use of a variety of existing network technologies and standards to provide a safe line of rectification, providing non-synchronous transmission $ support, this is a sneak peek in the money and decoration, color. Usually In other words, mobile handheld devices are powered by batteries, because f is symmetrical, both sides must consume electricity in transmission; and in ^, provide Yu-villa will touch the family ship from 6_ county Under the device, 'there are three advantages to using this kind of gradual content delivery: first, at the fixed network home = the server can provide greater data throughput and thus shorten the transmission time; the second provider It can avoid long-distance transmission and reduce energy miscellaneous; third, both the provider and the receiver can: the two parties are not required to be in the same network environment at the same time, and can freely provide a set of double money lion industry. In addition to the invention, the present invention implements a virtual case on the virtual battleship to establish a temporary effect: the cedar through the virtual _ system and the dynamic access point can be mutually _, _ protect the receiver file 荦 ,, this I am also working on the virtual server on the server. The size of the transaction process is determined by the age of the county. The failure is not arbitrarily accessed through the protection of the home server. 201038032 Invention:: The above is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.
