A method for assigning wireless interface measurement control identifier

Abstract

The invention discloses a method for allocating a wireless interface measurement control identifier. When UTRAN needs to start a wireless interface measurement control and apply for a measurement control identifier for it, it is judged whether the started measurement control belongs to the measurement control that must be used for the basic algorithm function. If it belongs, it will directly return the measurement control ID corresponding to the currently started measurement control in the static area of ​​the measurement control ID allocation table; if it does not belong, then choose an idle measurement control ID in the dynamic area of ​​the measurement control ID allocation table and return the current The selected measurement control identification, and at the same time update the measurement control identification allocation table. The invention can not only ensure that the measurement control necessary for basic algorithm functions can be allocated to the measurement control identification, but also enable the measurement control of other functions to be allocated to the measurement control identification in time, which is beneficial to the smooth execution and further expansion of UTRAN functions.

Description

technical field [0001] The invention relates to wireless interface management technology, in particular to a method for allocating wireless interface measurement control signs in a WCDMA network system. Background technique [0002] In the WCDMA network system, the Universal Terrestrial Radio Access Network (UTRAN) starts the corresponding measurement of the UE by sending a radio interface measurement control message to the user equipment (UE). The message must contain a measurement control identification information element for Uniquely identifies a measurement control. Usually, the radio interface between the UTRAN and the UE is called a UU interface, and the measurement control identifier allocation table is used to record the usage of the measurement control identifier. [0003] The 3rd Generation Partnership Project (3GPP) agreement stipulates that the value range of the measurement control identifier is 1 to 16, which means that a UE can not start more than 16 measure...

AI Technical Summary

Problems solved by technology

Although the method of statically allocating measurement control identifiers is relatively simple to implement, its disadvantage is that when the total number of measurement controls for all possible UU interfaces activated by a UE exceeds 16, UTRAN cannot implement measurement control beyond 16 Even if the allocation of the total number of UU interface measurement controls within 16 can be temporarily met, this allocation scheme is not conducive to meeting the demand for an increase in the number of UU interface measurement controls after the UTRAN function is enhanced

However, once the number of UU interface measurement controls used at the same time exceeds 16, there are some defects: the excess UU interface measurement control cannot be started normally because the measurement control identification cannot be applied for before other measurement control identifications are released. Moreover, if the UU interface measurement control that needs to be activated is precisely the measurement control that must be used for basic algorithm functions, such as the same-frequency measurement used for soft handover decisions, if this measurement control cannot be activated, serious consequences such as call drop will occur. , so the dynamic allocation cannot completely guarantee that the measurement control that must be used by the basic algorithm function can be allocated to the measurement control identifier
