Problems solved by technology

[0004] However, with the increase of LPN cells, the network deployment environment becomes more complex and also brings some problems
First of all, because the coverage area of ​​LPN cells is much smaller than that of macro cells (Macro Cells), and the capacity is relatively small, some LPN cells may be overloaded by users, which will affect user data. Throughput, while some other LPN cells or macro cells will be at a relatively low load level. If the load is to be balanced, the network side needs to perform load balancing operations, but this process is not flexible enough, especially when there are many cells. The load imbalance caused by the lack of sex is even more serious
In addition, due to the large number of LPN cells, when the UE moves within the network, it will cause frequent inter-cell handovers (Handover), resulting in frequent data service interruptions or even call drops, which will also cause user data Throughput and user experience degradation
At the same time, this frequent switching will also cause the terminal and the network, especially the core network, to receive a large amount of signaling impact, which may lead to system resource congestion or even paralysis

Embodiment 1

[0059] Image 6 It is a schematic diagram of the implementation flow of the data forwarding method in the embodiment of the present invention, such as Image 6 As shown, the data forwarding method in the embodiment of the present invention includes:

[0060] Steps S101-S102: When an interaction message between the MeNB and the SeNB passes through the mobility anchor, the mobility anchor allocates GPRS tunnel protocol information, and notifies the MeNB or SeNB of the allocated GPRS tunnel protocol information. Wherein, the GPRS tunnel protocol information includes a transport layer address and a tunnel endpoint identifier. Specifically, based on Figure 5 Under the shown dual connectivity network architecture, in the dual connectivity SCG bearer, the mobility anchor notifies the MeNB or SeNB of the allocated GPRS tunnel protocol information, including:

[0061] During the preparation process for adding SeNB, the mobility anchor forwards the GPRS tunneling protocol informatio...

[0073] Figure 7 It is a schematic diagram of the implementation process of the data forwarding method of an application example of the present invention Figure 1 , the application example takes the SCG bearer as an example, which involves the SeNB addition preparation process in the dual connectivity architecture, and this process is the case where the interaction message between the MeNB and the SeNB is encapsulated in the X2 message transmission message. Such as Figure 7 As shown, the data forwarding method includes the following steps:

[0074] Step 201: The MeNB sends an X2 message transfer (X2 MESSAGE TRANSFER) message to the mobility anchor, where a SeNB addition request (SENB ADDITION REQUEST) message is encapsulated in the X2 message transfer message.

[0075] Specifically, the MeNB encapsulates the SeNB addition request message into the X2 message transmission message, and adds the identity of the source MeNB and the identity of the target SeNB in ​​the X2 messag...

[0086] Figure 8 It is a schematic diagram of the implementation process of the data forwarding method of an application example of the present invention Figure II , the application example takes split bearer as an example, which involves the SeNB addition preparation process in the dual connectivity architecture, and this process is the case where the interaction message between the MeNB and the SeNB is not encapsulated in the X2 message transmission message. Such as Figure 8 As shown, the data forwarding method includes the following steps:

[0087] Step 301: MeNB sends a SeNB addition request message to the mobility anchor;

[0088] Here, the SeNB addition request message is not encapsulated in the X2 message transmission message, but is directly sent to the mobility anchor through the MeNB, and the SeNB addition request message includes the identity of the source MeNB and the identity of the target SeNB. The SeNB addition request message includes the MeNB X2AP ID, bea...

Abstract

Provided are a data forwarding method, a mobile anchor point and a computer storage medium. The method comprises: when an interactive message between a master evolved Node B (MeNB) and a slave evolved Node B (SeNB) passes through a mobile anchor point, the mobile anchor point allocating general packet radio service (GPRS) tunnel protocol information, and informing the MeNB or the SeNB of the allocated GPRS tunnel protocol information, the mobile anchor point being a mobile anchor point established between the MeNB and the SeNB.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a data forwarding method and a mobile anchor point. Background technique [0002] With the continuous evolution of wireless communication technologies and standards, mobile packet services have been greatly developed, and the data throughput capability of User Equipment (UE, User Equipment) or terminals has been continuously improved. Taking the Long Term Evolution (LTE, Long Term Evolution) system as an example, it can support data transmission at a maximum downlink rate of 100 Mbps within a 20M bandwidth. In the subsequent enhanced LTE network, the data transmission rate will be further increased, even reaching 1Gbps. [0003] In order to meet the growing demand of data traffic and the characteristics of geographically uneven business, operators are also adding low power nodes (LPN, Low Power Node) during the process of deploying new generation communicat...
