Based on above-mentioned correspondence, UE identifies that the process of the data packet corresponding to different bearer can be as follows：

First, downlink data packet is sent to UE by eNB by physical layer；

Then, UE is by crossing the PDCP layers of itself, rlc layer, MAC layer, PHY layer, the lower line number transmitted by resolving inversely eNB According to packet.In the resolving of the downlink data packet, if corresponding to including in the MAC layer data packet of the downlink data packet LCID, then UE the correspondence of the LCID and DRB ID of UE is sent to according to the LCID and eNB（Or LCID and SRB ID Correspondence）, so that it may to determine the DRB ID corresponding to the downlink data packet（Or SRB ID）, and further will be to the MAC Rlc layer data packet obtained from layer data packet is decapsulated is sent to the DRB ID（Or SRB ID）Corresponding RLC entities, And then PDCP layer data packets obtained from being decapsulated to rlc layer data packet are sent to the DRB ID（Or SRB ID）Institute is right The PDCP entities answered.

By the above-mentioned prior art it is found that same be carried on different access phases and can use different types of carrying ID tables Show, their one-to-one relationship is as shown in Figure 6.In Fig. 6, this load identification of DL-TFT as shown in figure right side, in P- A protocol layer interface mark S5/S8-TEID can be mapped as in GW；And S5/S8-TEID can be then mapped in S-GW S1-TEID is identified for another protocol layer interface；Further, S1-TEID can be mapped to protocol layer interface mark in the enb Know RB-ID；And RB-ID can be mapped to this mark of UL-TFT in UE.

By taking EPS is carried as an example, it can be mapped to carry for various bottoms between the interface of different protocol layers, specifically reflect It is as follows to penetrate process：

MME is that EPS carryings are established in the service that UE is provided, and are sent to after determining the EPS ID of EPS carryings for S-GW eNB；

In the sides eNB, according to the mapping relations of the EPS ID and DRB ID that make an appointment, by the above-mentioned EPS ID received with DRB ID are mapped, to determine the DRB ID corresponding to the EPS ID；Meanwhile if control is also set up between the sides eNB and UE The signaling bear of UE and eNB Radio Links processed, i.e. SRB can then determine SRB ID；

When UE and eNB are communicated, UE obtains what eNB was sent by the DRB represented by the DRB ID that determine from physical layer Downlink data packet, the downlink data packet be decapsulated obtain MAC layer data packet when, UE is according in MAC layer data packet LCID and be sent in advance by eNB UE LCID and DRB ID mapping relations（The mapping relations can also be to make an appointment 's）, corresponding DRB ID are determined, so that it is determined that going out which RLC entity is the MAC layer data packet should be sent to.For passing through SRB And send downlink data packet for, similarly, UE according in corresponding MAC layer data packet LCID and sent in advance by eNB To the mapping relations of LCID and the SRB ID of UE（The mapping relations can also be to make an appointment）, determine corresponding SRB ID, So that it is determined that going out which RLC entity is the MAC layer data packet should be sent to.

According to above-mentioned mapping process it is found that UE is according to the mapping of LCID and LCID and DRB ID in MAC layer data packet Relationship, it may be determined that whether some downlink data packet comes from some special modality, such as comes from SRB0, or come from DRB5 Etc..

It is carried on different access phases according to same and can use different types of carrying ID expressions, and it is different types of Has this feature of one-to-one relationship between carrying ID, the specific implementation process of the present embodiment 2 includes mainly as shown in Figure 7 Following step：

Step 71, when some special modality of UE（The special modality can be specifically EPS carryings, radio bearer, logic letter Channel, transmission channel, physical channel between road, PCCP and RLC）Corresponding UL and DL data packets are by the first communication node（Such as The base stations Macro）When service, UE obtains the downlink data packet of the special modality from the first communication node；

Step 72, the first communication node configures the second communication node（It can be the base station of cell）Send special modality Downlink data packet；

Wherein, downlink data packet here can come from the rrc layer of the first communication node, PDCP layers, rlc layer, MAC layer it One.

Step 73, downlink data packet is sent to UE by the second communication node by special modality.

Step 74, UE receives downlink data packet from the second communication node, and by the decapsulation to the downlink data packet, obtains Obtain MAC layer data packet；

Step 75, UE is according to the LCID for including in MAC layer data packet, and the LCID with the determination of the first communication node in advance With the correspondence of different gap markers, the gap marker for corresponding to the LCID in the MAC layer data packet is determined；

Step 76, UE is determining, by the channel represented by the gap marker corresponding to LCID, to send downlink data When the communication node of packet is the second communication node different from the first communication node, by the channel（Special modality i.e. described previously） The upstream data packet third communication node that is sent to the second communication node or makes an appointment.

In example 2, the downlink data packet in Step1 and Step2 can be control signaling or business number According to corresponding downlink data packet.Control signaling can be RRC information, PDCP control signalings, RLC feedback signalings, MAC signalings, object Manage the corresponding signaling of control channel；And the corresponding downlink data packet of business datum, then can be specifically EPS carryings, DRB, LCH, The corresponding downlink data packet of transmission channel, Physical Shared Channel.

Usually, after the upstream data packet corresponding to the special modality is sent to the second communication node by UE, subsequently may be used also Further to receive downlink data packet from the second communication node.

By embodiment 2 it is found that when the UE that the first communication node is serviced receives the downlink for being respectively from different channels When data packet, it can be determined corresponding to downlink data packet according to the LCID in the MAC layer data packet corresponding to downlink data packet The mark of special modality, to be the different from the first communication node in the communication node for judging to send downlink data packet When two communication nodes, UE can be triggered, and to send this to the second communication node or the third communication node made an appointment specific Upstream data packet corresponding to channel.The process be the equal of by " UE determines the special modality communication node to be moved to " this One step, be transferred to the Radio Link between UE and the first communication node quality condition be also unlikely to trigger UE migrations it is specific logical It is carried out when road, to save the time needed for special modality migration.

Embodiment 3

Embodiment 3 primarily directed to UE there are one MAC entity or multiple MAC entities the case where.In this case, under UE identifications The process of special modality corresponding to row data packet is as shown in figure 8, include following key step：

Step 81, SRB（Or DRB）Corresponding data packet is sent to UE by the base stations Macro originally, and UE is also by corresponding Upstream data packet corresponding to PDCP- physical layer transmission respective carriers gives the base stations Macro.

Step 82, the base stations Pico（In embodiment 3, it can be assumed that the concept of the base stations Pico is equal to Small Cell）From Rrc layer, PDCP layers or rlc layer, the SRB between the base stations Macro and UE should be passed through by receiving the script transmitted by the base stations Macro （Or DRB）And the downlink data packet sent, and the downlink data packet is sent to UE using physical layer channel.

Wherein, the base stations Pico include specific LCID into the downlink data packet transmitted by UE or include specific MACCE and specific LCID, specific effect is see step 83.

Step 83, UE is by the downlink data packet received from physical layer channel after being descapsulated into MAC layer data packet, according to The content of LCID in MAC layer data packet, determine the downlink data packet that is received from physical layer channel be not received by before, Should the SRB between the base stations Macro and UE be passed through by the base stations Macro（Or DRB）And the downlink data packet sent；

Or UE can also be received upper according to the MACCE in above-mentioned MAC layer data packet, first determination from physical layer channel It states downlink data packet and comes from the base stations Pico, then, further according to LCID in MAC layer data packet, before learning that the downlink data packet is What is be not received by should be by the SRB between the base stations Macro and UE（Or DRB）The data packet carried.

Step 84, when UE identifies the above- mentioned information that LCID is characterized, or identify that MACCE and LCID are characterized After above- mentioned information, UE can restart（Or it is newly-built）The PDCP entities and RLC entities of the sides UE as shown in Figure 9, or only restart（Or it is new It builds）The RCL entities of the sides UE as shown in Figure 10.Here PDCP and RLC entities or RLC entities is corresponding with Pico.

Should specifically it restart（Or it is newly-built）Which entity depends on Small Cell namely Pico as shown in fig. 9 or 10 Initial tunneling layer of the base station to the downlink data packet transmitted by UE.If the protocol layer is PDCP layers, the sides UE need to restart （Or it is newly-built）PDCP entities and RLC entities, two entities as represented by Fig. 9 left-hand broken lines part；And if the protocol layer is RCL Layer, then the sides UE only need to restart（Or it is newly-built）RLC entities, an entity as represented by Figure 10 left-hand broken lines part.

Wherein, described to restart, it can refer to restarting for UE itself, can also be that an instruction information is sent by MAC entity To rlc layer, to indicate that RLC entities are restarted.

Step 85, UE controls MAC entity and MAC layer data packet is sent to RLC entities so that the carry out such as RLC entities are follow-up Unpacking process.

Step 86, script should be passed through the SRB between the base stations UE and Macro by UE（Or DRB）The upstream data of transmission encapsulates For upstream data packet and it is sent to the base stations Pico.

When carrying out upstream data encapsulation, by the SRB（Or DRB）Corresponding PDCP entities and RLC entities（Or it is only RLC entities）Package is carried out according to packet serial number SN used in the base stations Pico.Wherein, which can be exactly that the sides UE are used itself Packet serial number number, i.e. the initialization package serial number number of the sides UE, but under such scene, the base stations Macro need in advance by the sides UE itself The used packet serial number number is sent to the base stations Pico, and Pico is allowed to establish corresponding entity, to realize subsequently to upper line number According to the decapsulation of packet.

Embodiment 4

Embodiment 4 be also for UE there are one MAC entity or multiple MAC entities the case where.Due to embodiment 4 and embodiment 3 realization thought is similar, therefore the following main distinction point mainly introduced between the two embodiments：

In example 4, UE, by being decapsulated to it, obtains RLC after obtaining the downlink data packet that the base stations Pico are sent Layer data packet；Then, UE obtains the instruction information encapsulated in the rlc layer data packet.Wherein, the instruction information is for illustrating：Envelope The downlink data packet equipped with the instruction information comes from the base stations Pico；To which RLC entities are restarted in UE execution（Or RLC entities and PDCP entities）Operation.

Wherein, above-mentioned instruction information to illustrate the downlink data packet come from the base stations Pico.The instruction information can be one A explicit information；Or the instruction information is also an implicit information.For example, due to the base stations Pico RLC entities and Packet serial number SN used in the RLC entities of the base stations Macro belongs to different sets, therefore can be with the RLC entities institute of the base stations Pico The SN used is as the instruction information, i.e., implicit information.As it can be seen that the meaning of " implicit " is, has set meaning with one Information indicate other meanings, indicate that downlink data packet comes from such as used in the RLC entities of the base stations Pico SN here The base stations Pico.And the meaning of " explicit " can then be summarized as that the information for not having set meaning is specified to indicate certain meaning.

It should be noted that the base stations Macro can base stations SN and Macro used in the RLC entities by the base stations Pico SN used in RLC entities, which is pre-configured with, gives the base stations UE and Pico.
