Use-apparatus-measuring swichover method based on wireless network controller transference

Abstract

The method includes steps: after migration of radio network controller (RNC) is accomplished, new service RNC controls user devices to release all measurements under former service RNC; based on own measurement strategy, new service RNC controls user devices to execute relevant measurement. The invention makes new migrated RNC control UE quickly to switch executing measurement operation indicated by measurement strategy. The invention saves resources of air interface and operation resources on network side.

Description

technical field [0001] The invention relates to the technical field of Code-Division Multiple Access (CDMA, Code-Division Multiple Access) mobile communication, in particular to a user equipment measurement handover method based on radio network controller migration in a CDMA system. Background technique [0002] In the CDMA mobile communication network system, radio network controller (RNC, Radio Network Controller) relocation (Relocation) is one of the key technologies in the CDMA standard, and RNC relocation refers to the service of user equipment (UE, User Equipment) in the network system In the process of an RNC (SRNC, Serving RNC) changing from one RNC to another RNC, the migration can be divided into static migration and accompanied migration according to the location of the UE when the migration occurs. [0003] Please refer to Fig. 1 for details, which is a schematic diagram of the process in which the SRNC of the UE is transformed from one RNC to another RNC in the...

Problems solved by technology

[0026] It can be seen that the measurement behavior performed by the UE does not fully meet the measurement strategy requirements of RNC_B of manufacturer B

[0027] Switching the measurement behavior of the relocated UE according to the above process may cause the UE to retain the measurement types that have been established in the RNC, such as the measurement types b(2) and c(3) mentioned above. These measurement types may It will cause the UE to continuously report invalid measurement reports in the new RNC_B, because the new RNC_B does not require the UE to perform measurement behaviors of measurement types b(2) and c(3), and the UE still performs measurement types b(2) ) and c(3) measurement behavior, and continuously report measurement reports related to measurement types b(2) and c(3), which will cause unnecessary waste of air interface resources Uu and operational resources for processing invalid measurement reports on the network side Waste; and the measurement type b(2) performed under the original RNC_A may also cause interference to the correct execution of the measurement type b(1) by the new RNC_B. For example, the original algorithm design of RNC_B only measures one measurement type b, so the UE reports The measurement report b(2) may wrongly trigger RNC_B to be processed according to the algorithm of the measurement report b(1), which may easily cause network compatibility errors

[0028] In addition, the CDMA standard stipulates that for the same measurement type, the allocated measurement filter coefficients (measurement filter coefficients are denoted by C here) cannot exceed two, so using the above process may cause the UE to perform the same measurement type in the new RNC_B More than two measurement filter coefficients are required when measuring behavior: Assuming that the measurement types b(2) and c(3) mentioned in the example above belong to the same measurement type, their measurement filter coefficients are C b(2) ≠C c(3) , then b(1), b(2) and c(3) also belong to the same measurement type in the new RNC_B, so RNC_B attempts to measure the filter coefficient C b(1) ≠C b(2) ≠C c(3) When establishing the measurement type b(1), since the measurement filter coefficient has exceeded two, it does not meet the standard requirements, which will cause the establishment of the measurement type b(1) to fail
