Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only the present invention's part embodiment, instead of whole embodiments. Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment one
The open a kind of data relay transmission method of the present embodiment one, is applied to first user equipment, and with reference to figure 1, described method can comprise the following steps:
S101: receive the UE data packet from user equipment (UE).
Wherein, the data that described UE data packet comprises are user data or signaling data.
The source UE of described UE data packet, it is possible to be other UE outside described first user equipment, namely accesses the access UE of relaying UE. In other embodiments of the present invention, the source UE of described UE data packet, it is also possible to be the first user equipment of carrying the inventive method, i.e. relaying UE.
Original protocol stack of existing common UE, namely realize it to call, send the protocol stack needed for terminal function such as short message and comprise: for sending and receiving user data provides the data plane protocols stack of technical support, and for sending and receiving signaling data provide the surface protocol stack of technical support.
Wherein, data plane protocols stack comprises PHY (PhysicalLayer, physical layer) agreement, MAC (MediaAccessControl successively by bottom to upper strata, media get involved control layer) agreement, RLC (RadioLinkControl, wireless chain control layer) agreement, PDCP, IP, APP agreement; Surface protocol stack comprises PHY agreement, MAC protocol, rlc protocol, PDCP, RRC agreement and NAS agreement by bottom successively to upper strata, and UE is according to the function needed for its corresponding layer of the various protocol realization in above-mentioned protocol stack.
In order to realize relaying scheme, UE is called possessing, while sending the terminal functions such as short message, also possesses data relay effect, the data interaction being embodied as between access UE and mobile communication corresponding node of network (such as base station) provides data relaying function, with reference to the relaying UE protocol stack structure that figure 2 (a) and Fig. 2 (b) illustrates, the present embodiment adds a virtual relaying function sublayer between the rlc protocol layer and PDCP agreement layer of UE original data plane protocols stack and surface protocol stack, this sublayer can be the newly-increased sublayer (belonging to PDCP layer) of former PDCP layer RLC side, it can also be the newly-increased sublayer (belonging to rlc layer) of former rlc layer PDCP side, it can also be an independent agreement layer, can also be that the function to original PDCP or rlc layer increases.
On this basis, as shown in Fig. 2 (a) and Fig. 2 (b), using PHY, MAC, RLC, relaying function sublayer, each layer agreement of PDCP, IP/RRC, APP/NAS as UE function side agreement, it is achieved for UE provides support with UE role's sending and receiving base station data; Using PHY, MAC, RLC, each layer agreement in relaying function sublayer as relaying function side agreement, it is achieved the data accessing UE with relaying role's sending and receiving for UE provide support; Wherein, relaying function side and UE function side can independently possess its RLC, MAC separately and PHY layer, it is also possible to share one or more above-mentioned layer, agreement total in UE function side protocol stack and relaying function side protocol stack merged to realize, reduce redundancy.
Relaying function side and UE function side realize the logical cohesion of two function sides by its total relaying function sublayer, and based on this, UE is in the process of interim data, it may be achieved its role transforming between UE role and relaying role. Such as, UE is after UE function side receives, with UE role, the interim data bag coming from base station, it is corresponding format data packet by it in relaying function sub-layer processes, this data packet enters another relaying function side, function side afterwards, UE is relaying role by UE role transforming simultaneously, finally, relay data is forwarded with relaying role by the relaying function side of UE.
After increasing relaying function sublayer on original protocol stack basis, UE possesses terminal function and data relaying function simultaneously, forms relaying UE. As shown in Figure 3. Relaying UE can keep signaling and data cube computation with access UE and base station as relaying node simultaneously.
The application's method specifically for relaying function sublayer as the independent agreement layer of between rlc protocol layer and PDCP agreement layer, is explained by the present embodiment.
With reference to figure 4, so that row data on UE (namely UE need to send data to base station) is carried out relaying, assume that relaying function sublayer is independent agreement layer, then A1/A2/A3 is the wireless carrying from UE function side (relaying UE its data), namely transmit downwards by relaying UE applied layer and through PDCP process PDCPPDUIP bag; B1/B2/B3 is the wireless carrying from relaying function side, is specially the PDCPSDUIP bag that the rlc layer of relaying function side is upwards submitted, and carrying that this is wireless may for deriving from the data packet of an access UE, it is also possible to be the multiple data packets from multiple access UE.
In order to realize the differentiation of relaying morphological data (what derive from access UE treats interim data) with UE morphological data (relaying UE its data), the relaying function sublayer of the present embodiment possesses following function one or function two:
Multiple PDCPSDUIP bags, PDCPPDUIP packet aggregation from relaying function side and UE function side is mapped as the less preset format result data packet of number by the polymerization mapping ruler (the polymerization mapping ruler as formulated based on QoS, APN, IP address or signaling type etc.) that function one, foundation are preset; Such as, it is mapped as this polymerization mapping ruler of a big data packet according to by data packet identical for signaling type polymerization, it is achieved by data packet A identical for signaling typexAnd BxIt is mapped as a data packet Cx;
Wherein, described result data packet comprises former PDCPSDUIP bag or the PDCPPDUIP bag of correspondence mappings, and the source UE of described former PDCPSDUIP bag or PDCPPDUIP bag identifies, to realize relaying morphological data and the differentiation of UE morphological data.
Function two, according to mapping ruler one to one, by being mapped as the preset format result data packet of equal amts one by one from multiple PDCPSDUIP bags of relaying function side and UE function side, PDCPPDUIP bag, such as, by data packet AxAnd BxIt is mapped as data packet C respectivelyx1And Cx2��
Correspondingly, the described result data packet of function two comprises former PDCPSDUIP bag or the PDCPPDUIP bag of correspondence mappings equally, and the source UE of described former PDCPSDUIP bag or PDCPPDUIP bag identifies.
When the wireless carrying received only comprises a data packet, then directly by mapping ruler one to one, the PDCPSDUIP bag of reception or PDCPPDUIP are mapped as the result data packet of corresponding format.
If described relaying function sublayer is an independent sublayer, then with reference to, shown in figure 5, relaying function sublayer, according to the difference mapping principle, can increase a relaying protocol header (corresponding to function two) for each PDCPSDUIP bag or PDCPPDUIP bag; Or for increase a relaying protocol header (corresponding to function one) by the aggregated data bag of multiple PDCPSDUIP bag, PDCPPDUIP packet aggregation gained.
Fig. 6 shows composition and the form of relaying protocol header, specifically comprises:
D/C element: for representing that this bag is the signaling data of user data or control signal, represent when value is D that this bag is user data, represent when value is C that this bag is signaling data;
SourceID (source mark) element: represent that Data Source is UE side or relaying side, further specifically derives from which access UE of relaying side in order to mark;
L element: the length representing PDCPSUDIP bag or PDCPPDUIP bag;
R element: for keeping byte-aligned, according to L and the SourceID length used, fills with reservation bit.
Each PDCPSDUIP bag that aggregated data bag comprises or ODCPPDUIP all may correspond to an independent sub-head of relaying agreement, multiple sub-head merges into a relaying protocol header, or multiple PDCPSDU or PDU only has a relaying protocol header, this relaying protocol header comprises organizes D/C more, SourceID and L element, and respectively with multiple PDCPSDU or PDU one_to_one corresponding.
If the function that described relaying function sublayer is original PDCP or rlc layer increases, then:
In the data packet head form of original PDCP or rlc layer, increase the element of the various features such as characterization data source mark, data packet length such as above SourceID element, L element, or utilize the reservation bit R in existing PDCP or rlc layer data packet form to represent above-mentioned functions.
Above the arrangement and function of relaying function sublayer is defined the preprocessing part that can be used as the inventive method.
On this basis, if access UE need to transmit data (for user data) to base station eNB, there is data relay demand, with reference to figure 7, then access UE and produce user data in its applied layer, the user data produced carries out corresponding form encapsulation through each agreement layer (IP, PDCP, RLC, MAC) of the conventional protocol stack of this UE successively, and enters UE physical layer, finally the UE packet transmission being encapsulated as corresponding format is gone out by radio frequency.
In other embodiments of the present invention, when relaying UE need to transmit data to base station eNB, the applied layer of relaying UE produces data and it transfers to downwards PDCP layer, after user data is encapsulated as PDCPPDUIP bag (i.e. described first raw data packets) by PDCP layer, continue to transfer to it downwards relaying function sublayer.
S102: the first decapsulation process preset by described UE data packet, obtains the first raw data packets.
Still for user data, if relaying function sublayer is the independent agreement layer between rlc layer and PDCP layer, after then the physical layer of relaying UE receives the UE data packet of access UE, upwards transmit data packet, make it carry out decapsulation process through the PHY of relaying side protocol stack, MAC, rlc protocol layer successively, obtain PDCPSDUIP bag, be i.e. described first raw data packets, finally, PDCPSDUIP bag is forwarded to relaying function sublayer by rlc protocol layer.
