Description

Method and device for acquiring IUB port delay performance

The present invention relates to the field of communications, and in particular, to an IUB interface delay performance acquisition method and corresponding device between a radio network controller (RNC) and a base station (NodeB). Background technique

With the development of 3G data services, especially high-speed downlink packet access (HSDPA), high-speed uplink packet access (HSUPA) and other high-speed services, IUB interface to transmission resources Demand has increased dramatically, and the high cost of ATM transmission has seriously affected the profitability of 3G operators. Due to the low cost and easy accessibility of IP transmission, the IUB interface has a tendency to be IP. At the same time, the IP network is weak in terms of QoS guarantee. In order to meet the strict requirements of real-time services (such as voice) for delay and delay jitter, it is necessary to implement voice and data split transmission, and transmit real-time services such as voice from the dedicated line ( For example, IP over PPP over El), to meet the QoS requirements of real-time services, packet switched (PS) non-real-time services are transmitted from the IP public network to save transmission costs.

A possible networking mode of IP transmission on the IUB interface is shown in Figure 1 (other network networking modes are not excluded). The NodeB is integrated into the IP backbone network through access technologies such as Digital Subscriber Line (DSL). The RNC passes Fast Ethernet (FE)/Gigabit Ethernet (GE) is connected to the IP backbone network to implement IP transmission of the IUB interface of the NodeB and the RNC. '

Performance statistics is a basic measure when operators build and maintain commercial networks. Through performance statistics, operators can clearly understand the current operational status of the network, providing a basis for network planning, network maintenance and optimization, and service evaluation.

After the IUB port uses IP as the transmission mode, the delay of the data on the IUB port varies according to different bearer types, modes, and even IP network conditions. The delay data becomes the configuration L3 and L2 parameters (including RLC parameters, time window parameters, Out Loop Power Control (OLPC) The important basis of parameters, L2 cache delay, link delay, etc., is also the basic data for the operator to plan the IUB port IP network structure, select bearer mode, handover method and configuration. Therefore, performance statistics for IUB port transmission delay are essential.

Protocol 3GPP TS 32.403 describes methods and principles for performance statistics on the network side. For the RNC, basically, from the perspective of the process, it is divided into a Radio Resource Control (RRC) process, a Radio Access Bearer (RAB) process, a signaling connection establishment, a soft handover process, a hard handover process, The migration process and the process of switching between systems. According to this agreement, each equipment manufacturer provides operators with unified performance statistics function services. The statistical methods are divided into Cumulative Counter (CC;), Dynamic Variable Statistics (GAUGE), Discrete Event Registration (DER), and Status Check (SI). The statistical object classification is divided into RNC-based and cell-based statistical items.

As mentioned above, the transmission delay of the IUB port is an important basis for the configuration of the service parameters and the construction of the IUB port transmission network. However, the current performance statistics protocol does not take into account the statistics of the IUB port delay, so that the operator cannot obtain specific information from the performance statistics. Important data such as IUB port delay and delay jitter in the transmission mode, it is impossible to intuitively and comprehensively understand the current status of the IUB port transmission network and adopt better optimal configuration. Summary of the invention

The specific statistical methods of each statistical item in Table 1 are described in detail below.

Embodiment 1: CS service IUB port average delay statistics.

Set the statistics period in advance (for example: every 2 hours, each time is 5 minutes). In each statistical period (5 minutes), obtain the CS domain for each type of service on the RNC or cell (CELL). The IUB port delay value in the continuous process; see Figure 2, when the CS service IUB port average is delayed, the delay value of each type of service is added and divided by the corresponding number of statistics to obtain the average of each type of service. Delay.

For example, the CS domain has four service types, namely, a session type service, a flow type service, an interaction type service, and a background type service, and the average delay is separately calculated for the four types of services.

Assume that the ongoing services of the IUB port on the RNC or the cell are: Session-based services: 3;

Flow business: 2;

Interactive business: 1;

Background business 4;

The first session-type service reports the delay of the three IUB interfaces. The IUB interface delay value of each service in the process of its service is synchronized with the frame protocol between the RNC and the base station. The number of IUB port delay values is related to the frame synchronization period and the duration of each service); the second session class service reports two IUB port delay values; the third session class service has one IUB port. The delay value; in this statistical period, the specific calculation of the average delay of the IUB port of the session-type service is:

During the statistical period (for example, five minutes), after each service obtains the IUB port delay through FP synchronization, obtain the delay jitter according to the following method: For each type of service, calculate the multiple IUB ports corresponding to each service separately. The difference between the next delay value and the last delay value in the delay value is used as the IUB port delay jitter value of each service in the course of its service.

Let RTT(i) denote the IUB port delay value reported by the i-th time of a service, and use RTTV to indicate the jitter of the IUB port delay reported twice before and after the service.

RTTV(i)= |RTT(i) - RTT(i-l)|;

The average delay jitter refers to the average value of the RTTV calculated by the above formula for a certain type of service during the statistical period.

The average delay jitter of each type of service obtained in the current statistical period can be reported to the performance monitoring platform in the network.

The average delay jitter value of each type of service counted at the beginning of each statistical period is cleared. Embodiment 4: CS Service IUB port maximum delay jitter statistics.
