In the following description, for illustrative purposes, set forth many details, for example, flow chart and system configuration so as toUnderstanding to one or more embodiments of the invention is provided.However, for those skilled in the art it is apparent that these haveBody details is not required to practice the invention.
According to an aspect of the present invention, with determine the associated phone user in position request and access the Internet content.CauseThe offer of special net content is to be customized according to position, and provide in a series of network of local customs.Given local networkNetwork includes server, and the server is configured to include the content for being suitable for its position.The delivering of content is to pass through localBase station, cellular phone from the particular home network configured after this manner to user are realized.
For example, the information in relation to Hollywood can pass through Hollywood when detecting phone user close to Hollywood areaThe one or more cellular network base stations in area access.These base stations deliver internet content related with this area, such asWebsite in relation to film and movie star.What the base station that the internet content is saved in covering this area can easily accessIn server so as into the service area phone user provide faster with more efficient transmission.
By being optimized for position of the wireless network user to internet content, the present invention realize optimal data stream withVarious abundant informations and data from internet are accessed for phone user.
Fig. 1 is the block diagram for illustrating the system 100 according to the present invention for being configured to provide internet content delivering.System100 fundamental is user equipment (UE) 110, Radio Access Network (RAN) 120, core cellular network (CCN) 130, outsideNetwork (EN) 140 and local custom network (LCN) 150.
UE 110 is arranged to the cellular phone communicated with one or more base stations of RAN 120.Although UE110 are preferably cellular phone, it should be appreciated that, various equipment can be equipped with identical communication function.UE 110 otherExample includes personal digital assistant (PDA), set-top box, information station or any personal meter for being configured to have wireless communication abilityCalculate device.
RAN 120 and CCN 130 preferably implements the customary components of cellular network and is further described below.RAN120 include base station and radio network controller (RNC) element.Base station provides resource management, and provides for converting UE 110The interface of data flow between RNC.RNC controls the radio resource for the base station that it is connected to, and also manages and arrive UE110 connection.
CCN 130 is connected with EN 140.The most important example of EN 140 can be divided into two kinds: circuit switching (CS)144 network of 142 networks and packet switch (PS).142 network of CS is provided to be connected for the circuit switching of circuit-switched service, exampleSuch as telephone communication and ISDN.144 network of PS provides the connection for being used for packet data service.Internet is the very heavy of PS networkIt wants and famous application.
CCN 130 includes MSC/VLR, GMSC, HLR, SGSN and GGSN element.HLR (home location register) is storageSuch as database of the information of customer service profile etc.Service profile includes information, the information include the service allowed,Random zone, forwarding number etc..HLR stores 110 position UE in order to call and other information routers are to UE 110.
MSC/VLR (mobile services switching centre and Visited Location Registor) provides friendship to the UE for being located at current location respectivelyOperation and database are changed for carrying out circuit switching (CS) business.VLR is by the service profile of user, and about the position UEMore accurate information is stored in service system.CS connection by GMSC (gateway MSC), GMSC is located to external CS networkTie point switch.
SGSN (service GPRS (General Packet Radio Service) supporting node) is functionally similar to the function of MSC/VLR, stillIt is typically used to packet switch (PS) business.PS connection passes through GGSN (Gateway GPRS Support Node).
LCN 150 includes one or more computing devices, and the computing device is configured to include memory, working abilityWith interface to provide function described herein.LCN 150 includes being configured to provide the local service of customization internet contentDevice.LCN 150 is further configured to include access to content monitoring module, and the access to content monitoring module monitoring access to the Internet is simultaneouslyAnd determine the content of the designated position suitable for LCN 150.
Therefore LCN 150 executes monitoring relevant to the content being locally applicable in and cache.For function for monitoring, prisonDepending on including local IP access, determine that the user for being located at the position accesses those contents.For caching function, LCN 150Keep the cache for the internet content being locally applicable in comprising refresh to add new content and remove by deriving fromThe outmoded content that the information of function for monitoring determines.
For determine content whether be a kind of locally applicable technology be measurement access frequency.If being located at being permitted for the positionMulti-user determines to access specific internet content, then the specific internet content be just determined to be it is locally applicable andIt is comprised in cache in next reproducting periods.
In addition to carrying out monitoring and cache to locally applicable content, LCN 150 is configured to logically approachIn the base station (one or more) for the cellular network for being located at specific position.In one example, close in logic is by making LCN150 close physical proximity with related one or more base station (such as base station in same geographical area) Lai Shixian's.For example,LCN 150 can be located in the region of the determination postal region number (one or more) of metropolitan areas or covering metropolitan areas.It can replaceGround is changed, it is close in logic to be realized in the case where being not necessarily to and being physically adjacent to.For example, this can include LCN 150 by providingThe private resource of high bandwidth connection between local user is realized.In this example, LCN 150 is configured to without physicsLocally applicable content is more efficiently and quickly delivered in the case where neighbouring due to private resource.
According on the other hand, to further increase efficiency, the locally applicable content for giving LCN is organized in pointIn layer structure.The content of first layer is considered to have the content of the applicability of highest local.It is provided also according to first layer attachedAdd layer, a sequence of layer is gradually covered biggish geographic area (that is, the base station for being gradually covered greater number).According to a sideFace, the layering are related to the communication with the adjacent LCN for covering increased region, to determine the local content for being suitable for additional level.Thus, for example, first layer is applicable in content (for example, as being only LCN or small-sized local with the local for being located at first level granularityLCN group monitoring/determination) it is corresponding, the second layer and the local for being located at second level granularity be applicable in content (for example, by pairThe content often accessed within the scope of the large area that the access of several LCN in the large area of restriction is monitored to determineLogic " and " or intersection) corresponding, etc..
Therefore the operation of the system for updating LCN is described referring concurrently to the flow chart of Fig. 1 and Fig. 2.The mistakeThe internet content that journey starts from user's access to current location carries out monitoring 202.This is by monitoring CCN 140 and PSThe gateway of connection between 144 networks is realized to track the internet content that phone user is accessed.
It will be noted that the content of monitoring can be there are two beneficial use.One is adjust locally applicable contentDelivering, this can be determined by the access frequency of given position.Another kind be allow content supplier (such as businessman or otherCommercial entity) receive such instruction: those contents are locally applicable.This allows supplier's help or further of contentIt participates in determining that is locally applicable.For example, the businessman for being provided with the instruction of the local applicability of certain contents may wishPrestige enables the user of the range to obtain advertisement, coupon etc..
Together with the monitoring 202, make to request internet content base station (one or more) determination (one orIt is multiple) 204.This can find internet content is requested to send by checking VLR and HLR by base station execute.It answersThis notices that base station discovery is only that can determine a kind of mode of physical location.Other examples including but not limited to makeIt is determined with GPS, postcode, telephone number and IP address information.
Next step includes according to the monitoring 202 to base station (one or more) and determining (one or more) 204 come reallyFixed 206 contents being locally applicable in.The determination of local applicability is by determining that access frequency is performed.Alternatively, localApplicability can be by will request the position of user (base station) to carry out with position associated with requested content is identified asCompare to determine.
Then, for current (such as first) layer, content is loaded 208 logically close to the user's of given positionIn server.This can be loaded with internet content by arrangement and/or current (such as first) layer of other information/data takesDevice (one or more) is engaged in complete to realize so as to the data being stored in the server for phone user by base stationsOptimal and faster data transmission.For example, the server can be placed logically close to base station, wherein phone user is logicalThe base station is crossed to access the data being stored in one or more servers.
The process is according to requiring to iterate through multiple layers.If it is determined that 210 extra plays are to be updated, then step 202-208 are just performed and load next 212 (such as second) stratum servers (one or more) to use locally applicable content.Such asDescribed such, when layer increases, this preferably needs broader geographic area.The process continues until determination210: being determined and load without more layers needs.The number of layer in given system will according to application and according to requiring andVariation.Layering often refers to maximize the locally available content arrived and generates and manage needed for the layer for increasingly wide regionProcess resource between tradeoff.
The content for being stored in one or more base stations can refresh 214 according to any desired timetable or triggering.ForRefresh operation, process described above are repeated, are started again with first layer.It is outmoded interior to be perhaps otherwise determined as no longerIt is that locally applicable content can be removed, and can increase new content certainly during the refresh cycle.
Additional server can be according to requiring longitudinally and/or laterally to be increased.Longitudinal direction refers to can be to earnestIt manages position and increases server to cover first, second, third, etc. layer.Laterally refer to that increase is corresponding from different positions notSame server group (that is, a group is used for first layer, second group for second layer, etc.).
Regular timetable or a certain number of activities can be used in the refreshing of triggering layering.In 150 server of LCNInternet content according to should be from the request to internet content that base station is sent and the discovery content that updates be modified.StorageInternet content in the server refreshes in reasonable time, such as when the user of the not accessed content of server is floodedWhen.
Therefore server is loaded information for broadcasting and/or multicasting and/or any to be visited by phone userThe data asked are to realize the optimal transmission of the user in service area.
Locally applicable content can be according to requiring to be sent and be delivered to user.For sending locally applicable internetThe example of the communication path of content includes the relatively straightforward path by RAN 120, then passes through RAN by CCN 130120 path or other.
Various technologies can be used for reality to the request of internet content together with UE 110 (or other equipment) userNow by the locally applicable content of 150 cache of LCN.In one example, UE 110 promotes the request of internet contentInitial inspection is carried out to the content in locally applicable content, conventional access to the Internet is followed by, if the content provesIf being content lacking in the locally applicable content of current cache.In addition, according to the side of layering described aboveMethod can carry out attempting for the first time from first layer being followed by second layer, etc. to meet request.It is searched in response to specific requestThe number of plies of rope can change according to requiring.When specifying the searched number of plies to use up for current request, conventional internet is visitedIt asks and be used to retrieve content relevant to the request.
Various cache managements and network optimization technology can be used for managing locally applicable content.For example, complete association(FA), directly mapping (DM) and group (SA) mechanism that is connected can be used to determining particular content and can be stored on serverWhere technology example.In addition it is possible to using for ensuring block validity and for managing cache hit and missTechnology.Random, LRU (least recently used) and FIFO (first in first out) block alternative are that those can be used for pipeManage the scheme of the block in cache.
According on the other hand, present invention facilitates for mobile payment (or the transmitting and such as alarm of other informationEtc information reception) system scheme.Preferably, this respect of the invention realizes cellular network, wireless personal areaNet (WPAN) and wireless recognition technique.Various technologies can be used for these component parts, including but not limited to be used for Cellular NetworksThe 3G technology of network；Zigbee, Bluetooth or UWB technology for WPAN；And RFID (the example for wireless recognition techniqueSuch as NFC).

The signal of Figure 16 illustrates the control system for the multimedia communication between different user terminals.
According to the one aspect of the present embodiment, the change server being differently positioned in a network environment provides routing functionEnergy and linkage function, and function is bidirectionally provided.Therefore, this aspect provide content transmitting and reception and depend on company, instituteRespective protocol used in the equipment and such equipment connect converts such content in two directions.
According to the other side of the present embodiment, cellular television function is provided.Here, TV is in form and functionallyIt further include cellular communication feature and above-mentioned translation functionality.Preferably, it is one or more right to provide in cellular televisionUser should be allowed to access and watch in a manner of being similar to for accessing conventional TV channels in " channel " of cellular applicationThe received content of institute in this way.
Also according on the other hand, one or more embodiments of the invention be internet, wireless network, cable, DSL,Satellite and TV communication are provided and are effectively integrated, and enable to carry out the communication between potential different user terminals.User is wholeEnd includes home and office intranets apparatus (such as TV, computer) and wireless terminal (such as mobile phone, PDA).According to weIn the system that face is configured, administrative center (MC) receives, selects, converts, compresses, decompresses and routes the data to user's endEnd.Various examples be shown and once according to the introduction of aspect to those skilled in the art instructed to they comeSay that it will be apparent.As an example, for example those signals from fire perceiving device or theft sensor pass through MC system quiltIt is sent to cellular phone and/or 911 centers of user.One can be executed by MC system combination user terminal and other MC systemsA little processing functions.In other examples, the call (wireless or wired) of user is routed to specified by userPhone, mobile terminal, computer and/or TV.
MC system functionality includes being received, converted and being emitted to content in two directions.It further includes for inciting somebody to actionContent map and it is routed to the facility of various connected equipment and for storing the content used for Local or Remote equipmentData storage.
Reception, conversion and the transmitting of multimedia content can be executed using MC system in two directions.For example, this can be withIncluding receive and emit from cellular network, internet, PSTN, other administrative centers signal, and receive and transmitting come fromThe signal of user terminal, the user terminal include TV, monitor, diaper monitoring, video camera, fire alarm, theft sensor etc..
About conversion, MC system includes the conversion module with routine, for selecting, extracting, compress, decompress, adjustEntire data and change data format and/or power lever and/or data packet size/format.
MC system also includes mapping table and routing module.Mapping table is described further below.It matches telephone number, cablePort, the port DSL, IP address etc..Routing module is used to route data to destination by designated channel.Routing module allowsThe received data from each provenance inbound is routed, each provenance includes but is not limited to cable, radio and television and internet.It is also permittedPermitted to be routed to establish and receiving the various interfaces in terminal, various interfaces include but is not limited to RS232, USB2.0 and vision cablePort.Routing module receives the relevant information about routing from the result for the same routing checked in mapping table, and therefore realApply routing.
Finally, MC system includes the data storage of such as hard disk.This allows MC system to carry out storage content to help being directed toUser terminal faster with more effective data receiver and transmitting.MC system can also easily retain it is switched (such asIt is compression, encoded, having encrypted, decompressed) content is for subsequent other access.The switched contentIt can internally be provided or externally be emitted from MC system.
It should also be noted that MC system further includes that software and/or hardware is used to filtering and handling virus, such as is related to Cellular NetworksThe virus of network and respective cell communication.For example, when content is just emitted and received by MC system, MC system can periodically or be heldVirus signature is checked continuously.Therefore virus shielding (virus screen) process can be applied to multimedia content and their turnIt changes, and is in identical local (domain of MC system).This is useful, because virus shielding can be turned in multimedia contentMultimedia content is applied to before or after changing.Processing may include preventing or being isolated viral, the viral number of deletion detectedAccording to or file, and to other MC systems or external system convey attack there may be.
It may include the data grouping of for recognition purpose equipment when communicating inbound to MC system.This can beTo by the form of the relevant unique device identifier of each equipment of MC system administration.To depositing for mapping table inquiry unique identifier?.Once this is performed successfully, the corresponding information about communication process can be automatically collected from mapping table.
In addition, or alternatively, MC system (and/or CHS) is according to predefined agreement by reference to received dataThe part of grouping can obtain formatting, addressing and other information.For example, the information in received data grouping can indicate to useIn the format (such as TCP grouping) in internet of transmitting and for received format (such as data defined in 3G by WCDMAGrouping), and corresponding to the destination-address for having converted data format.Overhead in received data grouping can notifyMC/CHS is about next transport protocol and matched format.That is, removing institute's phase by the received data grouping of MC/CHSIt include some regulation extra datas outside the content-data of prestige.The information notifies MC/CHS about inbound data format transmission agreement,And there are also the outbound data formats and transport protocol that correspond to the data format.
For example, if data grouping includes identifier DI1, it is determined that the main TV (main that communication is destined in familytelevision).In similar example, all communications to locking equipment can be required according to same format and identical address.For example, convention video output can be by the cable between the output of the video of MC system and the video input of main TV(such as passing through coaxial cable, block cable, HDMI cable) is directly connected.About the example, MC system includes conventional defeatedOut for the connection to TV.
Also there is network-based connection, such as to personal computer (such as household LAN router) or directly arrive outfitThere is the connection of the TV of network interface card and related functionality.In these examples, address information (and the corresponding item in mapping tableMesh) may include particular device network address.MC system is equipped with the network interface card of their own and corresponding output to joinAdd these communications.Again as indicated by mapping table, these and other communications can be carried out (such as by using cellular telephone numberCode or directly communication of the local radio communication to cellular phone).
There can also be such situation, that is, need for the given multiple and different processes of equipment application and accordingly to convert and fixedLocation.For example, television set may be coupled to both the video output of network connection and MC system.As another example, it is noted that honeycombPhone can have the communication capacity of replacement.In these environment, mapping table also may include for specifying address, signal formatDeng multiple and different entries.
Therefore, the information in mapping table can also be associated with for some processing scope (category) generations to locking equipmentCode.For example, the processing scope code #1 for television set can indicate that inbound communication should be addressed, convert (if applicable)And TV is routed to by video output.Conventional television signal only may be supplied to TV by this.On the other hand, it is used forThe processing scope code #2 of television set can indicate that inbound communication should be addressed, converts and be routed by network connection.In addition, comparing other content, some specific contents need additional or different processing (such as convert, decrypt).Additional placeReason scope code (as device identifier) can be included in the number in data grouping.
Data grouping can also arrive MC system by differently providing.In one embodiment, data grouping may be embodied inIt is sent in the stem region of the packet data of MC system by source.In addition, data grouping sometimes can oneself include for convertingAnd/or the information of addressing equipment appropriate.For example, data grouping oneself may include the network address of destination equipment to replaceSame content is inquired in the mapping table.Such as another example, the key for decrypting content can also be provided in data groupingThe all or part of information.For another example another example, data grouping may include label whether to track viral shielding processInstruction through successfully completing.
Intending the equipment to work together with MC system can allow equipped with software and/or hardware, the software and/or hardwareThey are inserted into and convey information appropriate in the communication with MC system.For example, cellular phone can equipped with for MCThe software for the data grouping being properly configured is provided in the initial communication of system, the initial communication is directed toward destination equipment.
MC system depends on relevant device and destination for data is treated differently data.For example, from beeThe received data of nest network are selected and then by converting to be shown in the family or office with different type display screenOn apparatus.Similarly, some contents can more suitably be shown by mobile telephone display.
In addition, some data are also compressed and are reorganized in MC system, so that they have specific data packet sizeWith format with the requirement for matching associated transport network.For example, sent from wet diaper, fire alarm and/or theft sensorSignal can phone for transmission to user or 911 centers.The information can be by be compressed before wireless network transmissions, when makingWith its permission increased efficiency when radio communication channel.Furthermore it is possible to which application is safe and cryptographic protocol (such as SSL) and mistakePrevent agreement and encoding mechanism (such as Huffman, Solomon or Turbo LDPC coding) to ensure that transmitted information is protectedIt holds safety and is free from mistakes.
