In order that those skilled in the art more fully understand the scheme of the embodiment of the present invention, the embodiment of the present invention is described in further detail with embodiment below in conjunction with the accompanying drawings.
The means of communication, base station and the WAP of the embodiment of the present invention, it polymerize the communication system to be formed suitable for different system, the communication system being polymerized by LTE and WiFi is mainly introduced herein, but is not limited only to the system that is polymerized by above-mentioned LTE and WiFi.Before the concrete technical scheme of the embodiment of the present invention is introduced, first the communication system that LTE and WiFi are polymerized simply is introduced below.
LTE system has the advantages that wide coverage, supports high-speed mobile, while having the shortcomings that data rate is low, price is high, transimission power is big, is relatively more suitable for the scenes such as high-speed motion, outdoor a wide range of activity；WiFi system has the advantages that data rate is high, price is low, transimission power is small, while having, coverage is small, AP (Wireless Access Point, wireless access points）Between cut the shortcomings of Lost bags rate is high when changing, be relatively more suitable for the scenes such as geo-stationary, indoor small range activity.After LTE systems and the respective advantage and disadvantage of WiFi systems, the two is organically combined, gives full play to the advantage of the two, realizes the communication process of high efficiency, low cost by both polymerizable systems.Referring to Fig. 1, show the structural representation of a kind of LTE system and WiFi systematic polymerizations, wherein AP30 as WiFi system access bridge, the base station 20 of LTE systems can be directly connected to, base station receives mobility management entity MME (Mobility Management Entity) 10 PDNs issued (the Public Data NetWorks, public data network of LTE access networks）Data, and data are handed down to user equipment (UE) 40 by WiFi AP.For simple LTE system or simple WiFi system, the performance and handling capacity of whole communication system just can be significantly improved after two kinds of systems are organically combined, realizes that high efficiency, low cost communicates.
Structure is formed after the paradigmatic system shown in Fig. 1, a most key problem is when UE enters the coverage of WiFi system, and when having downlink data arrival, UE and WiFi AP is set up data cube computation, be this embodiments of the invention provide the following means of communication.Referring to Fig. 2, the flow chart of the means of communication of embodiment of the present invention embodiment 1 is shown, including：Step 101, base station receives the instruction message that mobility management entity is sent；The instruction message includes Positioned at the Media Access Control Address of the user equipment of WAP, the instruction message is used to indicate that the base station passes through user equipment described in the WAP paging.
After mobility management entity MME receives the downlink data notification message that gateway Serving GW are issued, i.e., it can send the above-mentioned instruction message for calling user device to base station.Generally, indicate that message can be presented as beep-page message, communicated in order that wireless access point AP accurately can be set up with user equipment, indicate that in message MAC (the Media Access Control, medium education of user equipment should be included）Address.
Because the instruction message that MME is issued is a kind of LTE message, in order that correctly parsing identifies the content for indicating message to the AP in WiFi system, base station needs to Reseal its instruction message received according to the requirement of AP protocol stacks, i.e., LTE instruction message is packaged into Wifi frame structure.
The difference for the protocol layer being polymerize according to LTE system and WiFi system, the instruction message after encapsulation is also different.If for example, LTE system and WiFi system are aggregated in RLC (Radio Link Control, wireless chain control layer agreement）Layer, the then instruction message after encapsulating is the RLC PDU that base station is generated;If LTE system and WiFi system are aggregated in PDCP (Packet Data Convergence Protocol, PDCP）Layer, the then instruction message after encapsulating is the PDCP PDU that base station is generated.
It should be noted that, for included in the MAC Address for indicating the user equipment in message, it can be that the user equipment with LTE and WLAN polymerizing powers voluntarily reports LTE network, specifically, user equipment can pass through attach request after powering（Attach Request) MME is carried to, it can also be asked when user equipment does synchronous with core net by tracing section updating（Tracking Area Update Request) MME is carried to, the present invention is not limited this.MME can be stored in MME after the MAC Address of user equipment is received as a part for the customer equipment context, and base station is handed down in case being added to when needed in instruction message.
Step 102, the base station sends the instruction message to the WAP, so that the WAP is communicated according to the Media Access Control Address with the user equipment.
AP is after the instruction message after receiving the encapsulation that base station is issued, just the blunt MAC addresses according to user equipment generate corresponding packet, for example, the MAC Address of user equipment is added to WiFi frame head, then packet is handed down to specified user equipment, the i.e. user equipment with above-mentioned MAC Address.
In this method embodiment, what is carried out between WAP and user equipment is point-to-point paging, therefore MME is handed down in the instruction message of base station should include the MAC Address of user equipment, such base Stand by the packet of generation could be handed down to specified user equipment by AP, AP is set up data cube computation with specified user equipment.It should be noted that, in order to realize point-to-point paging, user equipment will also judge whether the packet that AP is issued is directed to oneself by way of detecting MAC Address, if the MAC Address of user equipment itself matches with the MAC Address that AP is issued, user equipment can just receive the packet that AP is issued, and then data cube computation is set up with AP, carry out high efficiency, low cost communication using the carrier aggregation system shown in Fig. 1.It is corresponding with above-mentioned means of communication embodiment 1, the embodiment of the present invention additionally provides a kind of communication system embodiment 1, including base station, mobility management entity MME, wireless access points AP and user equipment (UE), wherein base station and MME belongs to LTE system, AP belongs to wlan system, and MME preserves UE MAC Address.Below using beep-page message as exemplified by indicating message, the Signalling exchange schematic diagram with reference to shown in Fig. 3 is simply introduced the information interactive process above-mentioned various pieces role and each several part.
Step 201, the UE with LTE and WALN polymerizing powers reports its MAC Address to network, and MME is received after the MAC Address of the UE, and the part as UE contexts is stored in MME.
Step 202, after MME receives the Downlink Data Notification message that Serving GW are issued, paging message is issued to associated base stations.If MME saves the MAC Address of the UE, MME also includes the MAC Address of the UE into the hair beep-page message under base station.
Step 203, base station encapsulates beep-page message according to AP protocol stacks, and the beep-page message after encapsulation is sent into AP (if without specified otherwise, AP herein refers to AP all in wlan system).
Step 204, just the blunt MAC Address according in beep-page message generates corresponding packet to AP, i.e., UE MAC Address is added to WLAN frame head, and packet is handed down into UE.
Step 205, UE judges whether it wants received data packet by way of detecting the MAC Address that AP is issued, if UE itself MAC Address is identical with the MAC Address that AP is issued, then it is assumed that packet is sent for oneself, should receive the packet.
It should be noted that, in embodiment 1 shown in above-mentioned Fig. 2 and 3, AP is received after instruction message, it can will directly indicate that message is transmitted to the UE of the MAC Address issued with base station, it need not recognize that base station sends the intention for indicating message, that is, base station only can issue instruction message, nothing to AP It need to pay close attention to whether AP can recognize.Certainly, in order that AP knows the intention of this communication behavior, while issuing instruction message to AP in base station, can also make that AP knows that it is currently received by certain means is an instruction message.For making AP identifications indicate the technological means of message, it will wouldn't be described in detail herein in follow-up expansion description.Referring to Fig. 4, the flow chart of the means of communication of embodiment of the present invention embodiment 2 is shown, including：Step 301, base station receives the instruction message that mobility management entity is sent；Described to indicate that message includes the Media Access Control Address and the exclusive wireless access point identification of the user equipment of the user equipment positioned at WAP, the instruction message is used to indicate that the base station passes through user equipment described in the WAP paging.
Step 302, the blunt exclusive wireless access point identification according to the user equipment of base station, it is determined that sending the WAP for indicating message.
Step 303, the WAP is communicated according to the Media Access Control Address with the user equipment.
Compared with embodiment of the method 1, the present embodiment is being realized outside the point-to-point paging between wireless access point AP and user equipment, and the AP that data cube computation is set up with user equipment further also is defined into privately owned AP.So-called privately owned AP refers to the AP for only allowing part contracted user's equipment to access, i.e. not all user equipment positioned at privately owned AP all can access the privately owned AP.In the present embodiment, by setting up the data cube computation between UE and privately owned AP, just it is avoided that instruction message is all broadcasted in base station to all AP, saves interface-free resources.
Specifically, a kind of privately owned AP implementation is determined as step 302, can be presented as：The mapping relations of the base station just exclusive wireless access point identification of the blunt service set according to the WAP and the user equipment, it is determined that sending the WAP for indicating message.
Can be SSID (Service Set Identifier) as a kind of implementation of service set, a kind of implementation of exclusive wireless access point identification can be CSG IDs (Closed Subscriber Group Identifier), the two --- correspondence.Whom MME will be not only with this clear and definite paging object by indicating that message sends the MAC Address of user equipment to base station；Also CSG IDs are sent to base station, whom the AP that calling user device is specifically used for the mapping relations by CSG IDs and AP SSID is. It is corresponding with above-mentioned means of communication embodiment 2, the embodiment of the present invention additionally provides a kind of communication system embodiment 2, as different from Example 1, MME in the present embodiment also supports calling optimization function, base station is configured between CSG IDs and AP SSID --- and mapping relations, AP is privately owned AP.With reference to the Signalling exchange schematic diagram shown in Fig. 5, the information interactive process above-mentioned various pieces role and each several part is simply introduced.
Step 401, the UE with LTE and WiFi polymerizing powers reports its MAC Address to network, and MME is received after the MAC Address of the UE, and the part as UE contexts is stored in MME.
Step 402, after MME receives the downlink data notification message that Serving GW are issued, paging message is issued to associated base stations, and the MAC Address of CSG IDs and UE belonging to UE are included in paging message.
Step 403, the mapping relations between blunt the CSG IDs and APs according to its configuration of base station ability SSID, search the corresponding AP of CSG IDs in beep-page message (AP herein refers to privately owned AP).
Step 404, after base station selected good AP, beep-page message is encapsulated according to AP protocol stacks, and the beep-page message and UE MAC Address after encapsulation are sent to the AP of selection.
Step 405, UE MAC Address is added to WiFi frame head by privately owned AP, and packet is handed down into specified UE, the data cube computation set up between privately owned AP and specified UE.Referring to Fig. 6, the flow chart of the means of communication of embodiment of the present invention embodiment 3 is shown, including：Step 501, base station receives the instruction message that mobility management entity is sent, and the instruction message is used to indicate that the base station passes through WAP calling user device.
Step 502, the base station sends the instruction message to the WAP, so that the WAP is communicated according to public medium access control address with the user equipment positioned at the WAP.
It is different from embodiment of the method 1, the present embodiment is not to carry out the point-to-point paging between AP and user equipment, but use broadcast mode to issue packet to all user equipmenies in AP coverages, therefore MME is handed down in the instruction message of base station without including the MAC Address of user equipment.Corresponding to the present embodiment, user equipment is received after instruction message, and whether oneself is directed to without the MAC Address detection AP having using it packets issued.Using the present embodiment technical scheme, in user equipment and AP Set up after data cube computation, also carry out high efficiency, low cost communication using the carrier aggregation system shown in Fig. 1.Corresponding with above-mentioned means of communication embodiment 3, the embodiment of the present invention additionally provides a kind of communication system embodiment 3, and unlike embodiment 1, MME need not preserve the MAC Address of user equipment.Below using beep-page message as exemplified by indicating message, the Signalling exchange schematic diagram with reference to shown in Fig. 7 is simply introduced the information interactive process above-mentioned various pieces role and each several part.
Step 601, after MME receives the downlink data notification message that Serving GW are issued, paging message is issued to associated base stations.It should be noted which associated base stations is the MME location area informations that can be registered according to UE determine to be handed down to.
Step 602, base station encapsulates beep-page message according to AP protocol stacks, and the beep-page message after encapsulation is sent into AP (if indicated without special, AP herein refers to AP all in wlan system).
Step 603, AP generates corresponding packet using UE public MAC Address, i.e., UE public MAC Address is added into WLAN frame head, and give all UE by the data packet broadcast.
It should be noted that in embodiment 3 shown in above-mentioned Fig. 6 and 7, if there is AP protocol stack identification to indicate the function of message, base station just can will directly indicate that message be sent to AP, i.e., the intention of base station transmission configured information is recognized by protocol stack；If AP protocol stacks indicate the function of message without identification, base station is while the instruction message after encapsulation is issued to AP, and should also make that AP knows that it is currently received by certain means is an instruction message.The realization rate for indicating message, which is simply introduced, to be recognized to AP below, mode in mainly being presented as following two：
One kind is, one instruction message identifier is set, while the instruction message after encapsulation is issued to AP in base station, it may also indicate that message identifier is handed down to AP, so that AP recognizes the instruction message according to the mark, i.e. what AP is intended that according to the clear and definite base station transmission message of the mark；
One kind is, definition carrying indicates the dedicated signaling of message between base station and AP, instruction message after encapsulation is sent to AP by base station by the dedicated signaling, so that AP recognizes the instruction message according to the dedicated signaling, i.e. what AP clear and definite base stations by way of dedicated signaling sent message is intended that what.Referring to Fig. 8, the flow chart of the means of communication of embodiment of the present invention embodiment 4 is shown, including: Step 701, base station receives the instruction message that mobility management entity is sent, and the instruction message includes the exclusive wireless access point identification of the user equipment, and the instruction message is used to indicate that the base station passes through WAP calling user device.
Step 702, the blunt exclusive wireless access point identification according to the user equipment of base station, it is determined that sending the WAP for indicating message.
Step 703, the base station sends the instruction message to the WAP, so that the WAP is communicated according to public medium access control address with the user equipment positioned at the WAP.
The present embodiment is similar to the mentality of designing of embodiment of the method 3, it is the UE broadcast paging messages into wlan system coverage, except that, embodiment 3 is the packet for broadcasting generation to UE by all AP in WiFi system, embodiment 4 is then to carry out data broadcasting by specified privately owned AP, the AP all broadcast paging messages that can so avoid base station all under covering, save resource.Therefore MME, which is handed down in the instruction message of base station, should include exclusive wireless access point identification, a privately owned AP is specified with this, so the instruction message after encapsulation correctly could be sent to the privately owned AP specified by base station, and then the beep-page message after encapsulation is broadcasted from privately owned AP to all UE that can access the AP, the so-called UE that can access the AP refers to contracted user's equipment of the privately owned AP.
Specifically, a kind of privately owned AP implementation is determined as step 702, can be presented as：The mapping relations of the base station just exclusive wireless access point identification of the blunt service set according to the WAP and the user equipment, it is determined that sending the WAP for indicating message.
