Description

Uplink bandwidth configuration method and device

technical field

The present invention relates to the communication field, in particular to a method and device for configuring an uplink bandwidth.

Background technique

At present, the miniaturization and flattening of base stations is a rapid development direction of mobile communication systems. In a flat network structure, a wireless access point usually exchanges data with a gateway through a backhaul network, such as an asymmetric digital subscriber line (ADSL for short), microwave, and Ethernet. The uplink rate of the backhaul network has a certain limit. For example, the typical uplink peak rate standard of the ADSL protocol standard is 896Kbps, 1.2Mbps, 3.5Mbps, etc., and the maximum uplink rate of the mobile communication system may be greater than the maximum bandwidth of the backhaul network, such as UMTS. The HSUPA service supports transport layer peak rates of 5.74Mbps, 11.50Mbps, and 23Mbps in different versions of the 3rd Generation Partnership Project (The 3rd Generation Partnership Project, referred to as 3GPP). Therefore, there may be cases where the uplink service rate is greater than the available interface of the backhaul network. bandwidth scenarios. In addition, the bearer used by the backhaul network interface is generally a public network. There are situations where the same wired access point carries multiple access devices at the same time, and the total actual bandwidth may exceed the maximum bandwidth supported by the backhaul network. If the uplink rate is not adjusted, there will be a phenomenon that the air interface has correctly decoded the data, and due to the limited bandwidth of the backhaul network, transmission packet loss will occur, which will affect the rate of the application layer. This not only causes poor user experience, but also causes waste of air interface resources and reduces the efficiency of the entire wireless network.

Matching solves the problem in the related art that the uplink service rate of the backhaul network does not match the bandwidth of the backhaul network, improves the transmission efficiency of uplink transmission data, and saves air interface resources.

Here we take the third generation (3rd Generation) network as an example. For example, in the Universal Mobile Telecommunications System (UMTS for short), the home base station (Home NodeB, referred to as HNB) and the home base station gateway (HNB Gateway, referred to as the maximum uplink access rate of the interface between HNB GW), as the maximum uplink access rate supported by the backhaul network. Of course, other network elements may also be used in other networks, and are not limited to HNB and HNB GW.

Preferably, the maximum uplink subscription rate for wired broadband access on the Iuh interface between the HNB and the HNB GW can be obtained as the maximum uplink access rate supported by the backhaul network. Obtaining the maximum uplink access rate supported by the backhaul network in this way is simple, convenient and easy to operate.

Here we take the third generation (3rd Generation, referred to as 3G) network as an example for illustration. Preferably, when configuring the maximum uplink transmission rate of the wireless access point, the high-speed uplink can be configured according to the maximum uplink access rate supported by the backhaul network. The maximum uplink transmission rate of the High Speed Uplink Packet Access (HSUPA) service. Of course, other services may also be used in other networks, and are not limited to HSUPA services.

As a preferred implementation manner, the maximum uplink transmission rate of the wireless access point may be configured to be equal to the maximum uplink access rate supported by the above-mentioned backhaul network. In this manner, uplink transmission can be performed at the highest possible transmission rate while ensuring a low packet loss rate in uplink transmission.

In addition, in order to further match the maximum uplink transmission rate of the wireless access point with the maximum uplink access rate supported by the backhaul network, after initially configuring the maximum uplink transmission rate of the wireless access point, the maximum The uplink transmission rate is fine-tuned.

As a preferred implementation, it can periodically detect whether there is indication information indicating that the data packets transmitted by the wireless access point are discontinuous, and if the indication information is received, the maximum The uplink transmission rate; and if the indication information is not detected, the maximum uplink transmission rate of the wireless access point may be increased.

In order to make the increase speed of the available bandwidth slower than the decrease speed, C3 is smaller than C1 and C2, and because the priority of RTP packets is higher, when the RTP packets are discontinuous, usually the GTP-U packets are also discontinuous, when the GTP-U When the packets are discontinuous, the RTP packets may be continuous, so C1>C2 can be made. Therefore, as a preferred implementation manner, C1>C2>C3 can be set.

Preferably, the continuity of the data packet can be judged by reading the sequence number (Sequence Number, SN for short) field in the data packet through the continuity of the SN field in the data packet. This judgment method is simple and easy to operate.

Embodiment one

This preferred embodiment provides a method for configuring the uplink rate of the wireless access point based on backhaul network bandwidth detection for the scenario where the wireless access point in the flat network transmits data to the base station gateway through the backhaul network. The method controls the uplink transmission rate , so that it can be adapted to the available network bandwidth of the backhaul network, so as to achieve the most efficient data transmission.

This preferred embodiment is introduced by taking the WCDMA system as an example. The miniaturization of WCDMA base stations has caused changes in network element functions, interfaces and networking methods. In this preferred embodiment, a 3G home base station (3G Home NodeB, referred to as HNB) is used as a wireless access point, which is connected to a 3G home base station gateway (3G HNB Gateway, referred to as HNB GW) through an Iuh interface. Aiming at the available bandwidth of the wired access network at different rates of the Iuh interface between the HNB and the HNB GW and the maximum uplink HSUPA rate supported by the HNB, this preferred embodiment proposes a method for controlling the maximum uplink rate of HSUPA. Detection can accurately and dynamically adjust the uplink rate of the HSUPA service so that it can match the wired bandwidth of the Iuh port to achieve the optimal data transmission effect.

The method for controlling the HSUPA maximum uplink rate in this preferred embodiment includes the following steps:

Step S2, record the maximum uplink access bandwidth value A allocated by the wired access operator or obtained through testing into the configuration table of the 3G home base station in the 3G home base station management system (Home NodeB Management System, referred to as HMS).

In step S4, during the preparation process of the 3G home base station, the HMS sends the maximum uplink access bandwidth value A to the HNB through a message.

In step S6, the HNB GW checks whether there is a discontinuous data packet according to the Iuh interface user plane data detection, and if so, notifies the HNB through a message. After receiving the message, the HNB adjusts the maximum uplink service rate of HSUPA, and can adjust the maximum uplink service rate of HSUPA in time according to the value A and whether there is a discontinuous indication of data packets.

Through this preferred embodiment, no matter what kind of backhaul network the Iuh interface is, the HSUPA uplink service rate can be adjusted according to the initial configuration value, so as to achieve the effect that the uplink rate of the 3G home base station is accurately adapted to the wired broadband.

Embodiment two

In actual networking, the maximum uplink transmission rate of the backhaul network can be limited by the adopted protocol standard and the contract with the cable broadband operator. Therefore, by matching the maximum uplink transmission rate of the 3G femtocell with the maximum uplink transmission rate of the wired broadband access network, the entire communication system can transmit uplink data most efficiently and avoid packet loss of the uplink data of the 3G femtocell.

Fig. 4 is the schematic flow chart that carries out HSUPA speed regulation based on the detection result of Iuh mouth according to embodiment two of the present invention, as shown in Fig. 4, this flow process comprises the following steps:

In step S402, the HMS sets the maximum uplink bandwidth value A of the HNB according to the maximum uplink subscription rate of the wired broadband access, and enables the SN field in the GTP-U protocol for the Iuh interface user plane data field data packet.

Step S404, in the operation and maintenance process HNB preparation of HNB initialization, send the value A to the HNB through the HNB preparation message.

In step S406, the HNB sets the maximum uplink rate bandwidth as A1=A (assigning the value of A to A1) through the HSUPA scheduler, and schedules the maximum rate of uplink services according to the value A1.

In step S408, periodically check whether there is a discontinuous packet indication message, if yes, go to step S410, otherwise go to step S412.

Step S410, update the maximum rate limit of the HSUPA uplink service according to the indication values B1, B2 and the current maximum uplink bandwidth indication A1 (wherein, B1 is the corresponding indication value when the RTP packets in the data packet are discontinuous, and B2 is the GTP in the data packet -U indicates the value corresponding to discontinuous packets). If B1 is received, then A1=A1-C1; if B2 is received, then A1=A1-C2, where A1>0, then return to step S408.

Step S412, if not, then A1=A1+C3 and A1<=A. Then return to step S408.

C1, C2, and C3 dynamically adjust the available bandwidth step size; according to the voice service (Circuit Service, referred to as CS) and data service (Packet Service, referred to as PS) priority is different (for example, the priority of RTP packets and GTP-U packets) Different levels), and the principle that the increase of available bandwidth is slower than the decrease, which can guarantee C1>C2>C3.

After the adjustment of A1 is completed, the current UPA UE can also be calculated according to the maximum uplink rate bandwidth A1, the actual uplink bandwidth A2 used in the last scheduling period, and the bandwidth A3 corresponding to the scheduling authorization assigned to the UPA UE in the last scheduling period. Bandwidth A3=A1-A2+A3, and then limit the scheduling grants that UPA UEs can use according to A3, so as to further ensure that the maximum uplink rate bandwidth is limited.

Fig. 5 is a schematic flow diagram of the HNB GW detecting discontinuous packets and sending a corresponding indication to the HNB according to Embodiment 2 of the present invention. As shown in Fig. 5, the flow may include the following steps:

Step S504: Perform protocol detection on the User Datagram Protocol (UDP) packet, remove the header, and analyze and judge if the payload of the UDP packet is a Real-time Transport Protocol (RTP) packet, then Go to step S506, if it is a general packet radio service tunneling protocol (General Packet Radio Service tunneling protocol-User data, GTP-U for short) packet at the user level, then go to step S510.

Step S506, detecting the sequence number (Sequence Number, SN for short) field in the RTP packet, if it is non-continuous, then enter step S508.

In step S508, the HNB GW sends a discontinuous packet indication to the HNB, and the sending indication value is B1.

Step S510, detecting the sequence number (Sequence Number, SN for short) field in the GTP-U packet, if it is discontinuous, then enter step S512.

In step S512, the HNB GW sends a discontinuous packet indication message to the HNB, and the sending indication value is B2.
