Embodiment 1

[0092] Embodiment 1 is: during the RRC establishment process and the subsequent RB establishment / modification / release process, the implementation process of the user changing cell access method in a high-speed environment.

[0093] In the process of RRC establishment, the implementation flow of the method for user-changing cell access in a high-speed environment includes the following steps:

[0094] Step 201, the RNC obtains the RSCP and AOA received by the PCCPCH of the local cell and the adjacent cell through the RRC connection request message.

[0095] In step 201, obtaining the RSCP received by the PCCPCH of the local cell and the adjacent cell from the RRC connection request message may be: reporting the RRC connection request message to the RNC on a random access channel (RACH). The RACH measurement information is encapsulated in the RRC connection request message, that is, the RSCP received by the PCCPCH of the local cell and the neighboring cell.

[0096] Wherein, th...

Abstract

The invention discloses a user subdistrict switching access method under the high speed environment. The method includes the following steps: obtaining the received signal code power (RSCP) received by a primary common control physical channel (PCCPCH) of the subdistrict and the adjacent subdistrict, the angle (AOA) between a subdistrict uplink signal channel and an antenna, and the moving direction of user equipment (UE); determining the subdistrict switching access according to the decision mode of the RSCP received by the PCCPCH and the UE moving direction; or determining the subdistrict switching access according to the decision mode of the AOA and the UE moving direction; or determining the subdistrict switching access according to the decision results of the two decision modes. The invention also discloses a user subdistrict access system under the high speed environment. The user call is better realized under the high speed environment by adopting the method and the system.

Description

technical field [0001] The invention relates to a cell-changing access technology for a user, in particular to a cell-changing access method and system for a user in a high-speed environment. Background technique [0002] With the rapid development of maglev railways, high-speed railways and highways, mobile communication in high-speed environments has become a current concern. At present, maglev railways, high-speed railways and highways used in high-speed environments are usually designed as straight lines or curves with small radians. scope. For the design of cell coverage in a high-speed environment, adopting this simple coverage networking method avoids the problems of frequent switching and frequent reselection caused by complex coverage networking methods, which is conducive to later network adjustment and optimization. [0003] In a high-speed environment, users are in a fast-moving state. Taking Shanghai's commercial maglev railway as an example, its top speed ca...
