Under a fifth generation mobile communication (5th generation, 5G) non-independent group Network (NSA) EN-dc (eNB NR dual connection) dual-connection network architecture, an LTE base station (evolved node B, eNB) serves as a master base station (master evolved node B, MeNB) of a UE, a New Radio communication (New Radio, NR) 5G base station (eNB NR-next generation node B, EN-gbb) serves as a secondary base station, the LTE base station eNB is connected to an Evolved Packet Core (EPC) through an S1 interface, and the NR base station EN-gbb is connected to the LTE base station eNB through an X2 interface. How to reasonably control network flow is very important for the actual experience of the current network users and the reasonable utilization of resources. If the shunting is not reasonable, the influence on the current network user is large, the user experience of the current network user is seriously influenced, the bearing capacity of the LTE side is too large, and the unreasonable situation that the NR side still has vacant resources is caused.
Referring to fig. 1, a schematic structure diagram of an EN-DC network system provided in the prior art is shown. The EN-DC network system includes an Evolved Packet Core (EPC) layer and an evolved Universal Mobile Telecommunications System (UMTS) terrestrial radio access network (E-UTRAN) layer. The EPC layer includes a Mobility Management Entity (MME)/serving gateway (S-GW). The E-UTRAN layer includes 5G base stations en-gNB and 4G base stations eNB. Wherein the en-gbb provides NR user plane and control plane protocols and functions for 5G network users. The eNB provides NR user plane and control plane protocols and functions for 4G network users. The interface between the en-gNB and the en-gNB is an X2-U interface, the interface between the en-gNB and the eNB is an X2 interface, and the interface between the eNB and the eNB is an X2 interface. The interface between the en-gNB and the MME/S-GW is an S1-U interface, and the interface between the eNB and the MME/S-GW is an S1 interface.
Currently, there are some shunting schemes, which are roughly classified into static shunting and dynamic shunting. The static shunting directly sets the data traffic transmission proportion of the LTE network and the NR network, and is continuously carried out according to the proportion during shunting; most of the dynamic flow distribution schemes are that LTE side flow distribution is carried out simply when the service flow is judged to be larger than a certain threshold, and only the data volume in a buffer of a data buffer to be transmitted is considered; there are also offloading algorithms that maximize the transmission based on the amount of traffic that the networks on both LTE and NR sides can carry.
Based on the above technical background and the problems existing in the prior art, referring to fig. 2, an embodiment of the present invention provides a data offloading method, and the method mainly includes: and when data which cannot be transmitted completely by the NR device in the service buffer is considered for shunting by the LTE device, because the network bandwidth provided by the NR device is 100M and the LTE device is only 20M, shunting is performed only when the data cannot be transmitted completely in the service buffer of the NR device and the LTE device has resources which can be transmitted, so that the influence on the current network user at the LTE side is ensured to be small, and a shunting request of a user to be shunted in the service buffer is sent to the LTE device for allocating the resources of the LTE device. The LTE device periodically sends a offloading recommendation (i.e., offloading resources at a preset time) to the NR device through an X2 port shown in fig. 1, and informs the current maximum bearer, and the NR device performs an offloading decision according to the recommendation of the LTE device. The shunt suggestion of the LTE device is periodically reported to the NR device according to the actual situation of the LTE side network, after reporting, the NR device stores the suggestion value of the LTE device in its buffer, and periodically updates the suggestion value using new data, and the suggestion value is used when the NR PDCP (packet data convergence protocol) needs the LTE device to shunt. The method specifically comprises the following steps:
201. and the LTE equipment receives a shunting request sent by the new air interface NR equipment.
The offloading request comprises the service data volume of a user to be offloaded, a Channel Quality Indicator (CQI) and historical azimuth data of a preset time period; the historical orientation data at least comprises historical moving speed and historical moving direction; and the user to be shunted is an NR online user in the non-independent networking NSA.
For example, the historical azimuth data may further include an uplink Sounding Reference Signal (SRS).
202. And the LTE equipment calculates the position of the user to be shunted at the preset moment according to the historical position data.
203. The LTE equipment determines available resources according to the direction of the preset moment of the user to be shunted; the available resources are used for transmitting the service data of the user to be shunted.
Optionally, the available resources include idle resources; the LTE equipment determines available resources according to the direction of the preset time of the user to be shunted, and the method specifically comprises the following steps: and the LTE equipment determines unallocated idle resources in the LTE side network according to the direction of the preset time of the user to be shunted.
Optionally, the available resources include space division resources; the LTE equipment determines available resources according to the direction of the preset time of the user to be shunted, and the method specifically comprises the following steps:
the LTE equipment determines at least one first user paired with the user to be shunted according to the direction of the user to be shunted at a preset moment; wherein the first user is an LTE online user in NSA.
The LTE equipment acquires space division resources which are provided by at least one first user and used for transmitting service data of users to be distributed; the space division resources are space division multiplexing resources; the available resource plan includes a space division resource.
Optionally, the resource includes a preemptible resource; the LTE equipment determines available resources according to the direction of the preset time of the user to be shunted, and the method specifically comprises the following steps:
the LTE equipment acquires the data transmission rate of at least one second user; wherein the at least one second user is an LTE online user that does not include the second user in the NSA.
The LTE equipment classifies the data transmission rate of at least one second user according to at least one preset threshold, and calculates the classified at least one second user according to at least one preset shunt occupation ratio to preempt resources; wherein, the preemptible resource is a resource distributed in at least one second user; the preset threshold corresponds to the preset shunt occupation ratio one by one.
Illustratively, two preset thresholds (Th1, Th2) may be set, the second users with a rate greater than Th1 are classified as high-speed users, the second users with a rate less than Th2 are classified as low-speed users, the second users with a rate between Th1 and Th2 are classified as medium-speed users, the preset split ratios which can be set for the distribution of high-speed users, medium-speed users and low-speed users are sequentially P1%, P2% and P3% (only non-guaranteed rate (NGBR) bearers of the high-speed users, the medium-speed users and the low-speed users can be considered), the shunting proportion of the low-speed users is set to be higher according to a scheduling algorithm (such as a proportional fair algorithm or a polling algorithm), the shunting proportion of the high-speed users is set to be lower, namely, P1% < P2% < P3%, since preemption of high-speed user resources may cause a large reduction range of service rate, the throughput of the entire LTE network is greatly affected. The LTE equipment can dynamically adjust the proportion of distributable data according to the service volume of the cell.
204. And the LTE equipment calculates the shunting resources at the preset moment according to the available resources, the data volume and the CQI.
205. And the LTE equipment sends the shunting resources to the NR equipment.
For example, the LTE device may send the split resources to the NR device through X2 port as shown in fig. 1.
206. And the NR equipment sends the service data of the user to be distributed to the LTE equipment at a preset moment according to the distribution resource.
In the method, the LTE equipment calculates the azimuth of the user to be shunted at a preset moment according to historical azimuth data sent by the NR equipment; determining available resources according to the direction of the preset moment of the user to be shunted; then, calculating the shunting resources at a preset moment according to the available resources, the data volume sent by the NR equipment and the CQI; and sending the split resources to the NR device; and the NR device sends the service data of the user to be distributed to the LTE device at a preset time according to the distribution resource. The method and the device can more reasonably transmit the service data of the user to be shunted at the NR side by utilizing the network resource on the premise of ensuring the data transmission performance of the on-line user at the LTE side by calculating the shunting resource at the preset moment.
