Background technology
3GPP (3 at present
rdgeneration Partnership Project, third generation partner program) the just adjacent communication problem between research equipment and equipment of ProSe working group, if its main application scenarios is the equipment close together when communication, wish that transfer of data between equipment and equipment can directly be carried out between two equipment or forward by the serving BS of equipment connection, and need not pass through core net, thereby reduce the cost of serving of operator when can improving user's experience.3GPP is desirable to provide the adjacent communication service under network control completely.
The communication process of two equipment rooms that define in 3GPP in prior art, its data channel is as shown in Figure 1: UE1 (User Equipment, subscriber equipment) data are sent to eNB (the evolved Node B of service, evolved base station), and eNB can be delivered to data equipment of the core network Serving GW (the Serving GateWay of service, gateway) and PGW (Packet GateWay, packet data gateway), PGW can route data to according to routing table service PGW and the Serving GW of UE2, the Serving GW of UE2 service is delivered to data the eNB of UE2 service, pass to UE2 by eNB again.Example shown in Fig. 1 is the scene of the Serving GW when UE1 and UE2 service when identical with PGW, has now omitted the process that routes data to the PGW serving into UE2 for the PGW of UE1 service.
As seen from Figure 1, even if the position between two terminals of communication is very close, communication data also needs the eNB by serving separately, and core net could arrive opposite end, and communication delay is very large, but also can take the resource of network.Therefore 3GPP is studying now about the communication technology between nearby device, when even communicating pair distance is very near, can realizes between two UE communication or only realize high-speed traffic by the transmission of eNB.
Fig. 2 (a), Fig. 2 (b) is for realizing the data transfer path figure between terminal after adjacent communication.As shown in Fig. 2 (a), UE1 and UE2 can directly transmit, do not need through mobile network appliance, or as shown in Fig. 2 (b), when two UE are connected to same eNB, can pass through the eNB forwarding data of service, and not need data route to cross core net.This transmission means can reduce the time delay of transfer of data, and can save the Internet resources of the resource of network, particularly core net.
The demand of adjacent communication is being discussed at present in 3GPP SA1, according to result is discussed, adjacent communication roughly can be divided into two large class problems, and a class problem is the proximity relations discovery procedure between terminal, and Equations of The Second Kind problem is the problem how contiguous UE realizes direct communication.
Proximity relations discovery procedure between terminal is not only the prerequisite that realizes adjacent communication, also has a lot of application scenarioss simultaneously.For example businessman can send Discount Promotion advertisement to passer-by's terminal by detecting proximity relations, user can be by near the information such as restaurant and supermarket proximity relations discovery feature search current location, and bus station can be according to the proximity relations discovery feature forecast public transport information etc. of arriving at a station.
About the adjacent communication between terminal, what 3GPP paid close attention to is connection setup and the maintenance process under network control, and terminal can obtain adjacent communication service and traditional EPS (Evolved Packet System, Evolved Packet System) carrying data, services simultaneously.Adjacent communication is achieved many things at one stroke: the transfer of data load in core net can be alleviated in operator; User can obtain the shorter communication service of time delay; The adjacent communication demand of public safety and business application is met.SA2 has following description in the project verification file of adjacent communication:
Adjacent communication: two contiguous UE are by the communication of the communication path set up between UE.Lead nearly communication can be divided into two kinds: the direct communication between UE, between UE, pass through the communication of eNB route.It is English that the text is as follows:
ProSe?Communication:a?communication?between?two?Ues?in?proximity?by?means?of?a?communication?path?established?between?the?Ues.
The?path?for?discovery?and?communication?could?for?example?be?established
-directly?between?the?Ues
-network?based,e.g.routed?via?local?eNB(s).
Below other background technology the present invention relates to is introduced.
SDF(Service Data Flow, server data stream) refer to that the IP with certain " feature " wraps.People can come " mark " by name, or with identity card " mark ", IP bag is to identify with the combination of the data field of IP head in IP bag.For TCP (Transmission Control Protocol, transmission control protocol)/UDP (User Datagram Protocol, User Data Protocol) IP packet, to be represented by following five IP header fields (being called for short IP five-tuple): (three are positioned at IP head above, 2 next are arranged in UDP or TCP head): source IP address, target ip address, protocol type (UDP or TCP), source port Port, target P ort.TFT (Traffic Flow Template, data flow template) is exactly that one or more IP five-tuples form.SDF is exactly that the IP being identified by TFT wraps.A corresponding IP bag of SDF has identical TFT.
User can use multiple IP operation simultaneously.The corresponding one or more SDF of each IP operation.Some different SDFs have identical QoS (Quality of Service, service quality), and some different SDFs do not have identical QoS.Under same PDN (Packet Data Network, Packet Data Network) connects, the SDFs of identical QoS should carry to transmit by same EPS.There is different Q CI (QoS Class Identifier, QoS rank identifier) or ARP(Allocation and Retention Priority, distribute and retain priority) the SDFs of QoS can not transmit by same EPS Bearer.
A PDN connects corresponding to one or more EPS Bearer.Each EPS Bearer must have different QCI or ARP.Under an EPS Bearer, can there be one or more SDF.In the time that an EPSBearer is established, this EPS Bearer just has QCI+ARP, and has UL_TFT(up link TFT)+DL_TFT(down link TFT)
In the time of a corresponding SDF_TFT ∈ of SDF (certain) Bearer_TFT, this SDF is transmitted by this Bearer.Therefore, only under same PDN connects, just likely different SDF is transmitted by same Bearer.
In the time that an IP packet arrives, extract its IP five-tuple, while then judging IP five-tuple ∈ (certain) Bearer_TFT, this IP packet is transmitted by this EPS Bearer.
Business is not to send an IP bag, but has successively sent a lot of packets, these not IP packet in the same time just formed a SDF.The IP five-tuple intersection of all IP bags has just formed the TFT of SDF.
A SDF is mapped to the process that an EPS Bearer transmits and is called BB (Bearer Binding, bearing binding), the entity that completes DL data BB function is BBERF (Bearer binding and event reporting function, bearing binding and reporting events function) or PCEF (Policy and Charging enforcement function, strategy and charging execution function entity), the BB of up UL data completes in UE.EPS bearing binding is illustrated as shown in Figure 3.
LTE(Long Term Evolved at present, Long Term Evolution) in system, communication between UE is that the EPS carrying connecting by PDN realizes, if having proximity relations between terminal, terminal should communicate by direct or local adjacent communication path.Prior art does not provide the method that the communication between terminal is switched between EPS carrying and adjacent communication path in the time that 3GPP network provides adjacent communication service.
