Description

Method and device for obtaining access channel usage

This application claims priority to Chinese Patent Application No. 200710096931.6, entitled "Method and Apparatus for Obtaining Access Channel Usage," filed on April 16, 2007, the entire contents of which are incorporated by reference. In this application.

Technical field

The present invention relates to the field of wireless communications, and in particular, to a method and apparatus for obtaining an access channel usage situation.

Background technique

Mobile network operators need to establish and maintain wireless communication systems. Continuous network optimization is a task that all operators must face throughout the life cycle of wireless communication systems. Planning and optimizing the network requires the same effort as establishing and configuring the network. Especially as the functions of the communication system become more and more powerful, the parameters and alternative configuration options that need to be set are significantly increased compared with the previous network. It takes a lot of time and money to get the right settings. The proper setting is inseparable from the grasp of the actual operation of the network. At the same time of the development of communication technology, higher and higher requirements are also placed on the monitoring and management of the communication network.

In the wireless communication system, the base station indicates the RACH (Random Access Channel) configuration of the user equipment in the broadcast channel or the dedicated signaling through the downlink signaling, and the user equipment determines the random access process according to the configuration. Parameters such as transmission power and channel resources used. If the transmission power of the user equipment is too large, the noise of the communication system is increased, and the power is too small, which may result in a long access attempt time. Similarly, if the RACH resources configured by the base station are relatively small and the number of users is relatively large, the number of user equipments may be increased. The time required for the access to extend the access; if the RACH resource is allocated more and the number of users is less, the resource will be wasted.

It can be seen that, in order to provide good services for users while making reasonable use of the base station radio access resources, it is preferable to match the RACH configuration of the base station to the actual use of the access channel. In other words, understanding the actual usage of the access channel in the general case is a prerequisite for configuring the best RACH parameters for the base station.

In the prior art, operators usually use test instruments, such as road testers, to perform road tests throughout the network, that is, workers carry test instruments to different test sites, perform random access at test sites, and collect random samples. Various random access parameters in the access process, and the obtained parameters are used for network planning or optimization after statistics. Road test requires a lot of manpower and resources, and since random access may occur anywhere in the wireless network, it is quite difficult to choose a suitable road test location itself. Therefore, the number of times that operators conduct drive tests is often very limited, and even so, they have to bear huge costs. The actual use of wireless networks will change with a variety of objective conditions. It is difficult for operators to obtain timely and accurate information. It is often found that the parameters of a certain network need to be adjusted after receiving complaints from users, which reduces the users' Satisfaction.

detailed description

When performing the drive test in the prior art, the test instrument usually simulates various types of access at the selected test sites, and the access type (also referred to as the access reason) may be the data transfer initiated in the connected state. Data transmission, uplink synchronization, and non-access stratum procedures initiated in idle state, etc., all of which include a random access procedure. During the test, the random access parameters used in the random access procedure and the results of the access attempts are recorded, thereby obtaining the access channel usage. The actual random access procedure may occur on any user equipment. The random access procedure performed by the user equipment can reflect the actual network environment, rather than the use of the access channel in the simulated test network environment. And optimization provides an accurate basis.

Therefore, in various embodiments of the present invention, the usage of the access channel is obtained by monitoring the random access procedure in the actual operation of the network. The monitoring of the random access procedure can be performed from the user equipment side and/or the network side, and the various embodiments described below will be separately described.

In the first embodiment of the method for obtaining the access channel usage of the present invention, the user equipment records the usage parameters of the access channel in the random access process, and reports the information to the network side after the access is successful, and is performed by the network side. The reported information is counted. The access parameters of the access channel generally include the random access parameters used by the user equipment in the random access process, and may also include the access process parameters of the user equipment. The random access parameters reflect the user equipment in the random access process. For the utilization of radio resources, the access procedure parameters reflect the random access procedure experienced by the user equipment.

In this embodiment, the user equipment can use the flow shown in FIG. 1.

Step S110: After starting the random access procedure, the user equipment initializes the access procedure parameters. The access procedure parameters may include the number of attempts to access, the number of collisions, the type of access, and the like. As described above, the base station transmits the RACH configuration information in the downlink of the local cell, and informs the user of the RACH resource that the device can use in the random access process. The base station can transmit RACH configuration information in different manners, such as in a broadcast channel, or carry it in dedicated signaling.

Step S120: The user equipment calculates, according to the RACH configuration information received from the base station, a random access parameter to be used in the current access attempt, and the random access parameter usually includes the random access resource and the transmission power used by the current access attempt. In this step, a method of calculating a random access parameter in the prior art can be applied.

Step S130: Record the calculated random access parameters.

Step S140: Perform the current access attempt by using the calculated random access parameter.

Step S150: Determine whether the access is successful. If the process proceeds to step S170, otherwise step S160 is performed. Step S160: Record the access procedure parameters according to the result of the current access attempt, and go to step S120 to start the next access attempt.

Step S170: After the access is successful, the user equipment uplinks the recorded access channel usage parameters. Generally, after the user equipment is successfully accessed, the user equipment sends uplink signaling or uplink data to the network side. The usage parameters can be sent to the network side in the uplink signaling or uplink data. Of course, the user equipment can also use the dedicated uplink signaling or the usage parameters of the uplink data transmission record.

In this way, the network side can learn from the usage parameters reported by the user equipment that the random access procedure has undergone several attempts, several collisions, random access resources used for each access attempt, and each access attempt. Transmission power, access type, etc. used. It should be noted that, according to the configuration or requirement of the network side, which parameters are to be recorded and reported by the user equipment, for example, if the network side does not need to know the transmission power when the user equipment performs random access, the method may be performed in step S130. The transmission power is not recorded, or the transmission power is not reported in step S170. For example, if the network side does not need to know the access procedure parameters, steps S110 and S160 may be omitted, and if the access is unsuccessful, the process directly proceeds to step S120.

In this embodiment, the process on the network side may be as shown in FIG. 2.

Step S210: Receive uplink information of the user equipment. The uplink channel data or the uplink signaling after the user equipment is successfully accessed includes the access channel usage parameter reported by the user equipment.

Step S220: Parsing the access channel usage parameter recorded in the random access process of the user equipment from the uplink information after the successful access. According to the setting of the user equipment, the access channel usage parameter obtained by the network side may include random access used by each access attempt in the random access process of the user equipment. Resources, transmission power used per access attempt, number of attempts to access, number of collisions accessed, and/or access type, and parameters that other user equipment can record during random access.

Step S230: The network side collects usage parameters reported by the user equipment to learn how to use the access channel. The network side can select an algorithm for using the statistical parameters according to actual operation conditions, network planning, or specific needs of the optimization. For example, an algorithm similar to the statistical driving test data in the prior art can be used, and details are not described herein again.

After obtaining the access channel usage on the network side, the operator can determine whether RACH optimization and RACH optimization are needed according to its operation strategy and statistics.

After the application of the embodiment, the operator can obtain the access channel reported by the user equipment at any time during the running of the network, thereby improving the timeliness and accuracy of the information acquisition. The usage of the access channel is obtained along with the operation process. Operators no longer need additional manpower and material expenditures, reducing the cost of network maintenance.

In the second embodiment of the method for obtaining the access channel usage of the present invention, the user equipment may perform an existing random access procedure, and does not need to record and report the usage parameters of the access channel, but the network side accesses the access channel. Random access signals are monitored and recorded. In the embodiment, the network side can use the flow shown in FIG. 3.

Step S310: The network side receives a random access signal sent by the user equipment on the access channel. As described above, the network side informs the user of the RACH resources that can be used by the device in the broadcast channel or the dedicated signaling of the cell. In this step, the network side can monitor the random access signal on each RACH resource configured by the network.

Step S320: The network side records the receiving condition parameter of the random access signal. The receiving condition parameter generally includes whether the random access signal received on a certain RACH resource, whether the received random access signal can be identified, and the receiving power, the access type, and the like. Operators can decide which receiving parameters to record based on their optimization needs and specific networking conditions.

Step S330: The receiving status parameter of the network side statistical record is used to obtain the usage of the access channel.

After applying the embodiment, the operator can obtain the receiving channel parameters of the access channel at any time during the running of the network, not only can obtain the access signal usage in a timely and accurate manner, but also does not need to pay extra human and material resources, and reduces the network. The cost of maintenance. Compared with the first embodiment, the embodiment is only The network side implements that the user equipment is not required to modify the random access procedure, and the radio resources required for reporting the access channel usage parameters can be saved.
