Description

A method for verifying whether a base station can communicate normally

technical field

The invention relates to a WCDMA (Wideband Code Division Multiple Access) network and a CDMA2000 (Code Division Multiple Access 2000, Code Division Multiple Access 2000) network, and specifically relates to a method for verifying whether a base station can communicate normally.

Background technique

With the emergence of more third-generation mobile communication systems (such as WCDMA and CDMA2000) commercially available, the task of base station installation and commissioning will become more and more heavy. One day is responsible for the installation and commissioning tasks of several sites, which requires an extremely convenient call verification method that can be easily completed by one person to verify the installation of base stations.

As shown in Figure 1, in the prior art, a portable analog RNC (Radio Network Controller, radio network controller) is used to simulate the behavior of the network side, through its docking with the base station (NodeB), a cell is established, and two real UEs are supported (User Equipment, user terminal equipment) to verify the correctness of NodeB installation.

This method has the following disadvantages:

1) The cost is high, and each engineer needs to be equipped with two mobile phones;

2) It is inconvenient. It is extremely inconvenient for an engineer to use two mobile phones on site to call another mobile phone for verification through one mobile phone.

Contents of the invention

The technical problem to be solved by the present invention is to provide a method for verifying whether the base station can communicate normally, and overcome the disadvantages of high cost and inconvenient verification methods in the prior art.

In order to solve the technical problems, the present invention adopts the following technical solutions:

A method for verifying whether a base station can communicate normally, comprising the following steps:

A. After the simulated wireless network controller receives the call setup message from the user terminal equipment, if the called number in the message meets certain conditions, the verification process is started;

B. Buffering the user plane data of the user terminal equipment in an analog radio network controller, and sending the user plane data to the user terminal equipment after a predetermined time elapses.

The method, wherein: said step A comprises the following steps:

A1. The simulated wireless network controller sends a call processing message to the user terminal equipment;

A2, assigning an Iu interface user plane instance for processing user voice data, setting the peer Iu interface user plane instance of the user terminal equipment as itself;

A3. Send a ringing message and a connection message to the user terminal equipment;

A4. After receiving the connection confirmation message responded by the user terminal device, enter the call state.

The method, wherein: the step B includes the following steps: after the Iu interface user plane instance receives the uplink voice data of the user terminal equipment, allocate a certain buffer space, and cache the uplink voice data , start a timer at the same time, after the timer expires, send the buffered data as downlink voice data to the user terminal equipment.

Said method, wherein: a certain condition in said step A is: said called number is an 8-digit number.

Said method, wherein: a certain condition in said step A is: said called number is the local number of said user terminal equipment.

Said method, wherein: a certain condition in said step A is: said called number is a fixed number.

The invention has the beneficial effects of simple realization, cost saving and convenient use.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

In the present invention, the uplink voice data generated by the user speaking through the UE is buffered at the analog RNC side, and then sent to the UE as downlink voice data, so that the user can hear the content of his own speech in the earpiece of the UE, while the existing The simulated RNC can achieve this function with only minor changes:

After the simulated RNC receives the non-access stratum CC SETUP (call setup) message reported by the UE, it judges whether the called number carried in the message is a specific number (such as using an 8-digit number, or the UE's local number). number, or a fixed number); if it is, it is determined that the UE calls itself, and after the simulated RNC successfully allocates the Iu interface user plane (Iu UP) instance for processing the UE voice data, it directly sends CALL PROCEEDING (call connection) to the UE message; and identify the peer Iu UP instance corresponding to the Iu UP instance as itself; then, directly send the ALERTING (ringing) message and the CONNECT (connection) message to the UE, and wait for the CONNECT ACK (connection confirmation) that the UE responds to After the message, it enters the call state.

The UE converts the voice signal generated by the user's speech into uplink voice data and sends it to the simulated RNC through the air interface. After receiving the uplink voice data, the simulated RNC forwards it to the Iu UP instance corresponding to the UE for processing. The Iu UP instance receives the uplink voice After receiving the data, allocate a certain amount of buffer space to buffer the uplink voice data received from the user, and start a timer at the same time. After the timer expires, the cached data is sent to the UE as downlink voice data. Converted to a speech signal so that the user can hear his own voice through the earpiece. The purpose of starting the timer and delaying for a certain period of time is to facilitate the user to confirm that the content of his own speech heard is sent from the earpiece of the UE.

As shown in Figure 2, the specific operation steps are as follows:

After receiving the CC SETUP (call setup) message of the user terminal equipment for verification, a1 judges whether the called number carried in the message is the number used to identify the user terminal equipment for verification;

a2 If so, send a CALL PROCEEDING (call connection) message to the user terminal equipment for verification;

a3 allocate the Iu UP instance for processing UE voice data, and simultaneously set the peer Iu UP instance of the user terminal equipment used for verification as itself;

a4 sends an ALERTING (ringing) message and a CONNECT (connecting) message to the user terminal equipment for verification;

After a5 receives the CONNECT ACK (connection confirmation) message that the user terminal equipment that is used for verification responds, enter conversation state, will receive the user's uplink voice data buffer, start a timer simultaneously, after waiting timer overtime, Then the buffered data is sent to the UE as downlink voice data.

The protocol version used in the present invention is the R99 (2001.06) protocol, the main references are: 25.331, 25.415, 25.433, 25.413, 24.008; the protocol can be upgraded.

The beneficial effects brought by the technical solution of the present invention:

1. Save the initial cost, each engineer or each group of engineers only needs to be equipped with a mobile phone;

2. Easy to use, a mobile phone can easily verify whether the call can be completed;

3. The implementation is simple, and the existing analog wireless network controller only needs to be slightly modified.
