Description

Transmission delay reporting, application method and device

Technical field

The present invention relates to the field of communications technologies, and in particular, to a transmission delay reporting, application method and apparatus.

Background technique

RNC. At present, the RNC has two purposes for the TP value, that is, two requirements/uses: a) is sent to the base station in the dedicated channel establishment signaling to guide the placement of the search window; b) the RNC reports in the system The operator can use the TP reported by the RNC to evaluate the distribution of UE locations in the cell as an important reference for positioning, network planning, and optimization. In this use, the TP value is expected to reflect the distance of the UE from the base station as accurately as possible.

The TP value reported by the NodeB is calculated using the phase of the strongest energy path.

S1, receiving at least two TPs reported by the base station;

S2, the at least two kinds of TP are used for different purposes.

The at least two types of TPs may include at least a first TP calculated according to a radial phase (transmission delay) of the strongest energy path, and a diameter of the multipath according to the access search or a path of the multipath accessing the search. The second TP calculated by the energy weight center. The first TP can be used for the system, and the second TP can be used for sending the base station to guide the placement of the search window.

It can be seen that the embodiment of the present invention proposes another way to solve the problem compared with the prior art. In the embodiment of the present invention, the first TP obtained according to the phase of the strongest energy path (transmission delay) can more accurately reflect the distance between the UE and the base station, and therefore can be better applied to the network in order to perform the network. Optimization, traffic map, user location measurement application of mobile communication network, etc.; and using the second TP calculated according to the diameter center or the radial energy weight center to guide the placement of the search window, the calculated search window can be better.

Therefore, after reporting multiple TP values by using the technical solution of the embodiment of the present invention, the RNC can use different TPs for different needs, enhance the pertinence of different needs, and optimize the existing TP reporting mechanism.

In addition, in addition to the first TP and the second TP, those skilled in the art may also use the base station to upload For other purposes, the TP can be specifically designed according to actual needs, and will not be described herein.

The interaction between the base station and the RNC can be seen in Figure 2.

In other embodiments of the present invention, the reporting method may further include the steps of calculating the first TP and calculating the second TP.

Since the calculation method of the first TP is the same as that of the prior art, this article does not introduce too much. The following describes how to calculate the second TP.

A method of calculating the second TP may include: passing a formula

The diameter center P of the multipath of the access search is calculated, and P is used as the second TP. Wherein, P _i represents the transmission delay of the i-th path in the multipath of the access search (i is less than or equal to N greater than equal 1); and N represents the total number of paths of the multipath of the access search. The second TP calculated in this manner is the aforementioned second TP calculated according to the radial center of the multipath of the access search.

Another way to calculate the second TP can include: passing the formula

The diameter energy center P' is calculated, and P' is the second TP. Wherein, P _i represents the transmission delay of the i-th path in the multipath of the access search, E _i represents the path energy of the i-th path in the multipath of the access search; and N represents the multipath of the access search. The total number of paths. The second TP calculated in this way is the aforementioned second TP calculated from the center of the radial energy weight.

In addition, it should be noted that in the prior art, since only one type of TP is transmitted, the base is The station and the RNC have only one interface. In the embodiment of the present invention, at least two types of TPs are to be reported. Therefore, the interface between the base station and the RNC can be added, and the at least two types of TPs can be reported through different interfaces. The new interface can be a private interface. For example, for the first TP and the second TP, it can be reported through two interfaces.

It should be noted that the interface mentioned above may be a logical interface or a physical interface. The so-called logical interface can be implemented by reporting the at least two TPs through different FP group packets. Reporting different TPs through different FP group packets is logically equivalent to using different logical interfaces. Although in reality, these different FP group packets may be reported through the same physical interface.

Certainly, different FP group packages can be reported separately by using two or more physical interfaces, and those skilled in the art can perform flexible design, and details are not described herein.

In addition, in other embodiments of the present invention, the at least two types of TPs may also be reported by the same FP group package.

More specifically, in the existing FP frame, the Propagation delay field is used to transmit the TP value (that is, the first TP in the embodiment of the present invention). It is described in 6.2.7.5 of 3GPP protocol 25.435 that the existing TP (ie, the first TP) uses 8 bits. Currently, there are still 11 bits of idleness in the FP frame that are not used. Therefore, some or all of the bits in the FP frame can be used to transmit the second TP value. In addition, in other embodiments of the present invention, 1 bit of the idle 11 bits may also be used to indicate whether the second TP needs to be identified and processed.

Corresponding to the reporting method and the application method, the embodiment of the present invention further provides a TP reporting device and a TP application device. The TP reporting device can serve as a base station, and the TP application device can serve as an RNC.
