Description

Transmission control protocol confirmation message segment sending method and device

technical field

The invention relates to wireless communication technology, in particular to a transmission control protocol (TCP) confirmation message segment sending method and device.

Background technique

In order to effectively improve the coverage and increase the communication capacity of the system, the 3rd Generation Partnership Project (3GPP) standard organization is currently studying related technical standards for deploying small cells in the Long Term Evolution-Enhanced (LTE-A) system. The so-called small cell means that within the coverage of the original macro cell, one or more small base station clusters are deployed in a specific area according to different terrain conditions and customer needs, and the system capacity is increased through short-distance communication and wireless resource multiplexing . A non-ideal backhaul (backhaul) link is used to connect the small cell base station and the macro base station, so that the two have a certain cooperative communication capability.

When the user is within the coverage of the macro cell and the small cell at the same time, the radio resource control (RRC) online status of the two base stations can be maintained at the same time, that is, the macro cell and the small cell can serve the user at the same time, and the user maintains the macro cell and the small cell. Small cells have two physical communication links. In this way, the user's uplink and downlink communication rate can be effectively increased, and the communication capacity of the system can be increased.

When small cell (SmallCell) dual connectivity is applied, the Packet Data Convergence Protocol (PDCP) sublayer of a macro cell will follow the order of arrival from the core network and the load sharing strategy for each TCP confirmation segment of each data radio bearer (DRB) Submitted to the radio link control (RLC) logical channel corresponding to the macro cell and the small cell for parallel transmission, in order to obtain a satisfactory dual connection throughput.

At present, most of the mobile Internet services are business applications carried on the transmission service provided by TCP. When using dual connections, each user may use dozens to hundreds of TCP connections to access the Internet, especially for Hypertext Transfer Protocol (Http) business applications, and each Http business service will trigger dozens of TCP connections. connect. Due to the limited number of DRBs, in most cases, the IP packet streams of multiple TCP connections of different services will be carried by one DRB, which may cause the performance of different TCP services to affect each other.

The TCP service is connection-oriented. The service throughput of the TCP connection and the congestion window size of the sender will be affected by the feedback quality of the TCP acknowledgment segment fed back by the receiver. The maximum throughput of a TCP connection is equal to the TCP maximum sending window size divided by the round-trip time (RTT, Round-TripTime) of the TCP connection. The RTT is the TCP sender sending a TCP data segment to receiving the corresponding TCP confirmation segment time. Although the dual connection provides a wider wireless transmission link, under the condition of dual connection, it is possible that the TCP connection cannot make full use of the wireless transmission link provided by the dual connection because the TCP acknowledgment segment cannot be fed back in a timely and reliable manner. Satisfactory TCP connection throughput and user service experience.

In the existing multi-service application scenario, the TCP confirmation message segments (generated by the UETCP protocol) of multiple TCP connections corresponding to multiple downlink TCP services may be blocked by the TCP confirmation message segments of the uplink TCP services, and cannot be processed in time. Sending to the TCP service server through the wireless access network and the core network may even be discarded due to PDCP congestion, causing the TCP protocol of the TCP service server to perform timeout retransmission and TCP slow start processing to reduce the current TCP congestion window, even if The dual-link downlink air interface of the current access network has free physical resource blocks (PRBs) available for use, which will also reduce the downlink service throughput of the corresponding TCP connection. Similarly, the uplink TCP acknowledgment segment may be blocked by the TCP acknowledgment segment of the downlink TCP service. Even if the uplink air interface of the dual-link of the current access network has free PRB resources available for use, the corresponding TCP connection will be reduced. Uplink business throughput.
