Description

The transmission method of network element data and communication system in a kind of communication network

Technical field

The present invention relates to mobile communication technology, the transmission method and the communication system of network element data in particularly a kind of communication network.

Background technology

Mobile communication system in future, for example in back three generations (B3G:Beyond three Generation) or LTE-A (Long Term Evolution-Advance, long-term evolution upgrading), system will provide higher peak data rate and cell throughout, also need simultaneously bigger bandwidth, at present the following unassigned bandwidth of 2GHz seldom, the part or all of bandwidth that the B3G system needs can only be on higher frequency range, for example 3GHz is above seeks.Frequency range is high more, and it is fast more that radio wave propagation is decayed, and transmission range is short more, under the therefore same overlay area, guarantee continuous covering, needs more base station, because the base station has higher cost usually, this can increase the cost of arranging net undoubtedly.In order to solve the cost problem of arranging net, each manufacturer and standardization body begin one's study relaying (relay) are incorporated in the cellular system, increase to cover.

Fig. 1 introduces RN (Relay Node for the LTE-A system, via node) network architecture schematic diagram after, RN is linked into EPC (EvolvedPacket Core by the donor cell under the eNB (evolution base station) (alms giver sub-district), evolution block core net), do not have direct wave point with EPC, each RN can control one or more sub-districts.Under this framework, UE (User Equipment, subscriber equipment) and the interface of RN are called Uu so, and RN and DeNB and interface be called Un.

According to the discussion of present 3GPP (3rd Generation partnership project, 3 generation collaborative project), each company has proposed multiple candidate's protocol stack architecture now.Now wherein framework 1,3 is briefly introduced.

Framework 1 is as follows:

Fig. 2 is the schematic diagram of framework 1, and as shown in the figure, MME is (Mobility ManagementEntity) among the figure, and donor-eNB is a donor base station.RN has dual identity in this framework as seen from the figure:

At first, RN has the identity of UE, so it has oneself SGW/PGW (ServingGateway/PDN Gateway, gateway/PDN Gateway; PDN:Packed Data NetworkGateway, packet data network), be referred to as RN-GW (Tandem Gateway) among the application, the external node packet that is sent to RN all will pass through RN-GW so, RN-GW issues current serving BS DeNB (the donor eNB of RN then, donor base station is promptly controlled the base station of donor cell), DeNB issues RN on the Un mouth then.

Secondly, for the UE that inserts RN, RN has the identity of eNB, and this moment, the downlink data of UE need send to the serving BS of UE from the SGW/PGW of UE, i.e. RN, and RN issues UE on the Uu mouth then.And when the data of UE when UE-GW issues RN, this packet can pass through RN-GW, this moment, RN-GW can be considered as it to issue the data of RN, placed it in the EPS carrying of RN, issued DeNB earlier, issued RN again.

Fig. 3 is the U plane protocol stack configuration diagram of framework 1, and the U plane protocol stack framework of framework 1 as shown in Figure 1; Fig. 4 is the U plane protocol stack configuration diagram of framework 3, and the SGW/PGW of RN in the framework 1 is integrated among the DeNB, can obtain a kind of distortion of framework 1, is called framework 3, and its U plane protocol stack framework as shown in Figure 4.Wherein, each the agreement implication among the figure is as follows:

App.: use (Application);

TCP: transmission control protocol (Transmission Control Protocol);

UDP: User Datagram Protoco (UDP) (User Datagram Protocol);

IP: IP (Internet Protocol);

PDCP: packet data polymerized agreement (Packet Data Convergence Protocol);

RLC: Radio Link control (Radio Link Control) agreement;

MAC: medium access control (Media Access Control) agreement;

PHY: physical layer protocol;

GTP-u:GPRS tunnel protocol (GPRS Tunneling Protocol);

The L1:L1 layer protocol;

The L2:L2 layer protocol.

In RN-GW, EPS (Evolved Packet System, evolved packet system) carrying need be mapped in the EPS carrying of RN, issues DeNB then, DeNB uses the radio bearer of RN that packet is issued RN on the Un mouth, and RN issues UE with data on the radio bearer of UE on the Uu mouth then.In existing technical scheme, a plurality of UE EPS carryings are classified according to its QoS (Quality of Service, service quality) attribute under the RN, and the UE EPS carrying of identical QoS attribute can be mapped in the RN EPS carrying of same agreement.Down direction, the packet that each UE-GW sends all belongs to certain UE EPS carrying, UE-GW just fills in DSCP (the DiffServCode Point in IP packet header according to the QoS of this UE EPS carrying, the Differentiated Services code-point) issues RN-GW behind the territory, after RN-GW receives, check DSCP territory wherein, just know the QoS of the UE EPS that this IP bag is affiliated, send in the RN EPS carrying of agreement before placing it in then.Equally, up direction also is that so RN knows these mapping relations, therefore knows which RN EPS carrying the UE upstream data of receiving should be placed in.

But what the scheme of prior art was suitable for is user side data, and the characteristics of user face data are by EPS carrying transmission.And the inventor notices that in the invention process the deficiencies in the prior art are: be deployed with in the system of RN, RN as the base station can carry out alternately with other nodes, promptly receive and dispatch the IP packet, such as the various S1AP message between core network control surface node UE-MME (mobility of user equipment management entity) and the RN, the effect of message may be used to control RN, UE under the RN and the NAS between its MME (Non Access Stratum, Non-Access Stratum) message etc. also may have been carried.Again such as IP data mutual between RN and OAM (Operations, Administration and Maintenance, the Operations, Administration and Maintenance) node etc.How to transmit in RN EPS carrying as the IP data that do not have the QoS attribute mutual between this class wired network network element and the RN, this problem does not have solution as yet.

Embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present invention is described.

Fig. 5 is the transmission method implementing procedure schematic diagram of network element data in the communication network, as shown in the figure, when the data of transmission wired network network element, can comprise the steps:

Step 501, set up each RN EPS carrying and determine each wired network network element in the communication network, described wired network network element is the network element that logic interfacing is arranged with RN, and this wired network network element does not have the defined QoS attribute of LTE with the data that RN transmits;

The mapping relations of step 502, each carrying of foundation and each wired network network element;

Step 503, in corresponding RN EPS carrying, transmit the packet of each wired network network element according to described mapping relations.

In the enforcement, each wired network network element is meant that with RN logic interfacing is arranged, and the data that itself and RN transmit do not have the defined QoS attribute of LTE, comprise MME, MCE (Multi-cell/multicast CoordinationEntity, many cell multicasts coordination entity), MBMS-GW (MBMS gateway; MBMS:MultimediaBroadcast/Multicast Service, multimedia broadcasting multicast services), UE-MME, other eNB, other RN, OAM node etc., the said equipment is in wired network, MME, GW and MCE belong to equipment of the core network, and eNB, RN belong to the scope of Access Network, and OAM is not in the system architecture of 3GPP definition, but it carried out with all being connected by IP alternately of eNB, so can come to carry out transfer of data by RN EPS carrying by the scheme in the embodiment of the invention.For equipment of the core network, each equipment or be used for chain of command, perhaps be used for user's face: such as all MME and MCE all is the chain of command network element, all GW are user's veil units.

In addition, in the EPS standard, defined 2 kinds of options simultaneously, the two difference is on the S5/S8 interface: option one has adopted GTP based S5/S8 (seeing 3GPP TS 23.401), and option 2 has adopted PMIPbased S5/S8 (seeing 3GPP TS 23.402).In option one, PGW both had been responsible for distinguishing UE (i.e. the IP bag of identification arrival is to issue which UE's), also was responsible for distinguishing each EPS carrying under the UE (determining promptly the IP bag of issuing certain UE should be placed in which EPS carrying of this UE); And in option 2, PGW only is responsible for distinguishing UE (i.e. the IP bag that identification arrives is to issue which UE's), SGW then on the working foundation of PGW, is responsible for distinguishing each EPS carrying under the UE (determining promptly the IP bag of issuing certain UE should be placed in which EPS carrying of this UE).

The technical scheme that provides in the embodiment of the invention is applicable to 2 kinds of top options simultaneously, does not therefore specifically distinguish the PGW of RN and the SGW of RN in the description below, but the two is referred to as RN-GW.If that system uses is option one (GTP based S5/S8), that so described RN-GW refers to is exactly RN-PGW; And if system uses is option 2 (PMIP based S5/S8), that so described RN-GW refers to is exactly RN-SGW.

In the enforcement, the effect of setting up mapping relations in step 502 is:

At down direction, RN-GW receives from behind the IP of the wired network network element bag, can be according to mapping relations, and which RN EPS carrying decision should place it in transmits.

At up direction, need when sending message, can which RN EPS carrying it be placed it in according to the mapping relations decision and transmit to wired network network element (as MME etc.) at RN.

In concrete the enforcement, these mapping relations can be fixed, and content can not need frequent variations by determining as concrete implementers such as operators.

In the enforcement, mapping relations can have two kinds at least, and a kind of mapping relations can be the IP address of each wired network network element and the mapping relations of each RN EPS carrying; Another kind of mapping relations can be value or the value of ToS (Type ofService, type of service) territory (size is 8bit) and the mapping relations that each RN EPS carries in the DSCP territory (size is 6bit) of IP traffic mutual between each wired network network element and the RN.Enforcement to this dual mode describes below.

Need to prove that mapping relations can be that unit sets up with each wired network network element, such as being set to the mapping relations that certain RN EPS carries for certain wired network network element device UE-MME sets up one, being set to the mapping relations that certain RN EPS carries and set up other one for another wired network network element device OAM node simultaneously, can be independently between these mapping relations.In addition, for same wired network network element device, the RN EPS carrying of its up direction mapping and the RN EPS carrying of down direction mapping, the two can be identical or different, all can adopt the default EPS bearing of RN or the non-default EPS bearing of RN.

One, mapping relations are the IP address of each wired network network element and the enforcement of the mapping relations that each RN EPS carries.

1, the configuration of mapping relations.

When the configuration mapping relations, can mapping relations be disposed respectively to RN-GW and RN by OAM;

Perhaps, by OAM mapping relations are disposed to RN-GW, then when this RN EPS carrying is set up, by RN-GW TFT (Traffic Flow Template, the Business Stream masterplate) parameter of described mapping relations as the carrying attribute disposed to RN through RN-MME (Mobility Management Entity of via node).

Fig. 6 as shown in the figure, in concrete the enforcement, when the OAM node disposes mapping relations to RN-GW and RN respectively, can comprise the steps: for mapping relations being disposed the implementing procedure schematic diagram to RN-GW and RN respectively

Step 601, OAM are to RN-GW configurating downlink mapping relations;

Step 602, RN-GW use the descending mapping relations that disposed;

Step 303, OAM are to RN collocating uplink mapping relations;

Step 604, RN use the up mapping relations that disposed.

In the enforcement, before the configuration operation of OAM can occur in RN EPS carrying foundation, also can be after it.Can dispose RN-GW earlier in the enforcement, and then configuration RN.Because if the wired network network element in the mapping relations also comprises OAM itself, after should be earlier the RN-GW configuration being finished, the downstream IP data that RN-GW just issues follow-up OAM the configuration information place of RN correctly are mapped to corresponding RNEPS carrying and are uploaded to RN.If order is anti-, OAM may be difficult to arrive RN to the configuration information of RN so.

Fig. 7 is the implementing procedure schematic diagram through RN-MME configuration mapping relations, as shown in the figure, can comprise the steps: when the configuration mapping relations

Step 701, OAM are to RN-GW configurating downlink mapping relations and up mapping relations;

Step 702, RN-GW are to RN-MME collocating uplink mapping relations;

Step 703, RN-GW use the descending mapping relations that disposed;

Step 704, RN-MME are to RN collocating uplink mapping relations;

Step 705, RN use the up mapping relations that disposed.

In the enforcement, the OAM node disposes these mapping relations to RN-GW, when this RN EPS carrying is set up, gives RN as the TFT parameter of carrying attribute through the final configuration of RN-MME with configuration information by RN-GW then.Wherein RN-GW can occur in the RN EPS loading establishing process the configuration of RN, the bearing modification process after perhaps RN EPS carrying is set up.

In the prior art, the TFT parameter is all disposed in each EPS carrying accordingly, wherein contains elements such as far-end IP address, distal end slogan, local port number, protocol type.Above-mentioned mapping relations just can utilize one or more element to set up the corresponding relation of EPS carrying and wired network network element.

2, the use after the mapping relations configuration finishes.

In the process data packet of each wired network network element of transmission, can be:

When transmitting downlink data, determine according to the IP address in the IP packet header whether these data are produced by the wired network network element by RN-GW, if then this IP bag is placed in the corresponding RN EPS carrying of this wired network network element and transmits according to mapping relations;

When transmit ascending data, determine according to the IP address in the IP packet header whether these data mail to the wired network network element by RN, if then this IP bag is placed in the corresponding RNEPS carrying of this wired network network element and sends according to mapping relations.

In concrete the enforcement, at first establish the mapping relations of the IP address of gauze network element and the RN EPS carrying that certain is pre-configured.When a wired network network element can have a plurality of IP address, these addresses all can be mapped in the corresponding RN EPS carrying too.

In concrete the enforcement, when transfer of data, at down direction, after RN-GW receives that destination address is the IP data of RN, according to the source IP address in the IP packet header, in case the IP matching addresses with in the mapping relations that disposed then is mapped to it in certain pre-configured RN EPS carrying according to mapping relations, for example the non-default EPS bearing of certain of the default EPS bearing of RN or RN.

At up direction, RN is according to the target IP address in the IP packet header, in case the IP matching addresses with in the mapping relations that disposed then is mapped to it in certain pre-configured RN EPS carrying according to mapping relations, for example the non-default EPS bearing of certain of the default EPS bearing of RN or RN.

In the foregoing description, what mapping relations embodied is far-end IP address, does not get rid of other elements that use simultaneously in the TFT parameter in the enforcement, as the distal end slogan etc.
