Description

User data transmission processing method, device, system and computer storage medium Technical field

The present invention relates to the field of communications, and in particular to a method, an apparatus, a system, and a computer storage medium for transmitting and processing user data.

Background technique

With the rapid development of wireless multimedia services, people's demand for high data rates and user experience is increasing, which puts high demands on the system capacity and coverage of traditional cellular networks. In the traditional Long Term Evolution (LTE) cellular network, the macro base station provides access services for the user equipment (User Equipment, UE for short) as the only access side network element. In order to meet the user's demand for higher data rates and improve the spectrum efficiency of the cellular network, the 3rd Generation Partnership Project (3GPP) introduced a low power node (Low Power Node, LPN for short) as the Acer The supplement of the station provides access services for the UE. The LPN features low-cost, low-power, and easy-to-deploy. It can include hotspot deployment and enhanced coverage. It can effectively improve the data rate of high-rate data services in indoor or outdoor hotspots and improve remote areas or communities. Edge coverage. Generally, the LPN may also be referred to as a small base station, which may include, but is not limited to, a Home evolved NodeB (HeNB), a pico base station (Pico), and a Radio Remote Unit (RRU). Radio Remote Head (RRH) and Relay Node (RN). In a hotspot deployment scenario, in order to achieve high data rates and spectrum efficiency, a large number of small base stations need to be deployed intensively in the area. However, since the coverage of the small cell under the small base station is small, the probability of a handover failure occurs when the medium-high speed mobile UE passes through the small base station, thereby affecting UE service continuity. In order to improve the UE mobile performance after the introduction of the small cell, the industry proposes to ensure basic coverage by a certain base station (for example, a macro base station), and the UE always maintains a radio resource control (Radio Resource Control, RRC for short) connection with the base station, and small The cell serves only as a transmission point (TP) to provide a higher data rate and meet the user's power saving requirements. FIG. 1 is a schematic diagram of a dual connectivity architecture according to the related art. As shown in FIG. 1 , in this system architecture, a UE maintains a connection with at least two base stations and uses radio resources under two base stations, so that radio resource aggregation across nodes can be implemented. This architecture is usually called a dual connectivity architecture. . The two base stations connected to the UE have a certain management control capability and are generally referred to as a primary eNB (referred to as a MeNB), and the other base station is referred to as a secondary eNB (SeNB). After the UE accesses the MeNB, the dual connection can be implemented through the SeNB adding procedure. After the SeNB is successfully added, the SeNB can perform a series of management, for example, SeNB modification, SeNB deletion, and SeNB modification.

For each UE, on the control plane, the MeNB can connect to the Mobility Management Entity (MME) through the S1-MME, and the MeNB and the SeNB are connected through X2-C. On the user plane, for the MCG bearer, the MeNB can connect to the Serving Gateway (S-GW) through the S1-U, and the SeNB does not participate in data transmission to the user plane. For the split bearer, the MeNB can connect to the S-GW through the S1-U, and the MeNB can connect to the SeNB through the X2-U. For the SCG bearer, the SeNB can connect to the S-GW through the S1-U, and the MeNB does not participate in data transmission to the user plane.

2 is a schematic diagram of a user plane data protocol stack of LTE according to the related art. As shown in FIG. 2, the downlink data received from the core network through the user-level GPRS Tunneling Protocol for the User Plane (GTP-U) can be aggregated by packet data after being unpacked. Packet Data Convergence Protocol (PDCP) sub-layer, Radio Link Control (RLC) protocol sub-layer, Medium Access Control (MAC) protocol sub-layer and physical layer (PHY) is sent to the user equipment (User Equipment, UE for short); the uplink data is transmitted in the opposite direction to the downlink data. FIG. 3 is a schematic diagram of a split mode 1 of a user plane according to the related art. FIG. 4 is a schematic diagram of a split mode 2 of a user plane according to the related art. When discussing the dual connectivity of Release 12, 3GPP discusses the splitting mode of two user planes: one is 1A, and the bearer user plane of the UE on the MeNB and the SeNB is directly connected to the S-GW, as shown in Figure 3; One is 3C, and the MeNB performs a shunt anchor point. The data is shunted between the PDCP layer and the RLC layer, and sent to the MeNB and the SeNB for transmission, as shown in FIG. 4 .

FIG. 5 is a flowchart of adding a first SeNB to a UE for a dual connectivity user plane architecture 1A according to the related art based on an existing dual connectivity network architecture. As shown in FIG. 5, the process may include the following processing steps:

In the process of the UE, if the UE moves to the SeNB and detects the SeNB cell, the MeNB reports a measurement report, and the MeNB can determine, according to the measurement report, the SeNB adding procedure for the UE. The MeNB may send a SeNB Addition Request (SeNB Addition Request) message to the SeNB, where the SeNB Add Request message carries the GTP information of the S-GW end of the S1 transport bearer. The GTP information may include: a transport layer address and a GTP tunnel endpoint identifier TEID.

Step S504: The SeNB returns a SeNB Addition Request Acknowledge message to the MeNB, where the SeNB adds the GTP information of the SeNB end carrying the S1 transport bearer in the request acknowledgement message, the GTP information of the SeNB end carried by the downlink data carried by the bearer, and the bearer. The uplink data is forwarded to the GTP information of the SeNB side.

Step S506: The MeNB initiates an RRC reconfiguration complete message process to the UE, and after the UE reconfiguration is completed, the MeNB sends a SeNB Reconfiguration Complete message to the SeNB.

Step S508: The MeNB sends an E-RAB Modification Indication (E-RAB Modification Indication) message to the MME, where the GTP information of the MeNB end carrying the S1 transport bearer carrying the bearer on the MeNB is carried in the E-RAB modification indication message. There is GTP information of the SeNB end of the S1 transport bearer that is modified to the bearer on the SeNB. The GTP information includes: a transport layer address and a GTP tunnel endpoint identifier TEID.

Step S510: The MME returns an E-RAB Modification Indication Confirm message to the MeNB.

In addition, FIG. 6 is a flowchart of the UE based on the existing dual-connection network architecture. For the dual-connection user plane architecture 1A, the MeNB of the UE is unchanged, and the UE moves between the SeNBs. As shown in FIG. 6, the process may include the following processing steps:

In the process of the UE, if the UE moves from the source SeNB1 to the target SeNB2 and detects the target SeNB2 cell, the MeNB reports the measurement report to the MeNB, and the MeNB can determine, according to the measurement report, the SeNB change procedure for the UE. The MeNB sends an SeNB Add Request message to the target SeNB2, where the SeNB adds the GTP information of the S-GW end carrying the S1 transport bearer in the request message. The GTP information may include: a transport layer address and a GTP tunnel endpoint identifier TEID.

Step S604: The target SeNB2 returns an SeNB Add Request Acknowledgment message to the MeNB, where the SeNB adds the GTP information of the SeNB end including the S1 transport bearer in the request acknowledgement message, the GTP information of the SeNB end carried by the downlink data of the bearer, and the SeNB of the uplink data carried by the bearer. GTP information on the side.

Step S606: The MeNB sends an SeNB Release Request message to the source SeNB1 to release the source SeNB1.

Step S608: The MeNB initiates an RRC reconfiguration message procedure to the UE, and after the UE reconfiguration is completed, the MeNB sends an SeNB reconfiguration complete message to the target SeNB2.

Step S610: The MeNB sends an E-RAB modification indication message to the MME, where the GTP information of the MeNB end including the S1 transmission bearer of the bearer remaining on the MeNB in the E-RAB modification indication message further includes modifying the bearer to the target SeNB2. S1 transmits the GTP information of the target SeNB2 end of the bearer. The GTP information may include: a transport layer address and a GTP tunnel endpoint identifier TEID.

Step S612: The MME returns an E-RAB modification indication acknowledgement message to the MeNB.

In the case of the dual-connected user plane architecture 1A, during the UE's mobility, the MeNB needs to add a new SeNB to the UE or replace it with the SeNB served by the UE. The S1 user plane data is sent by the S-GW to the MeNB and the SeNB respectively, that is, the anchor point of the S1 user plane is located in the core network element S-GW. In the process of adding or changing the SeNB, the MeNB needs to initiate a path update (path update). The process updates the S1 bearer information. Usually SeNB is a small base. In the scenario where the coverage of the small base station is small and is densely deployed in the hotspot area, and the UE moves in a large number of densely deployed areas of the small base station, if the SeNB adds/changes each time, the core network element needs to participate in the interaction, which will result in Larger core network signaling load and delay in the SeNB management process.

In response to the above problems, no effective solution has been proposed yet.
