Problems solved by technology

However, the RRC Redirection method requires the UE to reselect the GSM system, and the reselection process generally takes a long time, which will affect the UE experience; the RAB Directed Retry method directly directly selects a GSM cell for the UE by the RNC, because it is randomly selected The GSM cell is for the new UE to access, and it is impossible to know whether the selected GSM cell is the cell with the best quality. Therefore, the UE adopts the blind handover method when handover

Embodiment Construction

[0031] In order to solve the problems existing in the prior art, the present invention proposes a new load balancing method from the TD-SCDMA system to the GSM system, that is, by judging that when the TD-SCDMA cell is congested, the TD-SCDMA Part of the UEs that are online and support GSM in the SCDMA cell are handed over to the GSM cell, so that the TD-SCDMA cell always has enough idle code resources, thus ensuring that new access UEs can successfully access the TD-SCDMA cell.

[0032] Based on the above introduction, the specific realization of the scheme of the present invention includes:

[0033] A load balancing method from a time division-synchronous code division multiple access TD-SCDMA system to a global mobile communication GSM system, the method comprising: when judging that a TD-SCDMA cell is congested, selecting a part in the TD-SCDMA cell An online user terminal UE supporting GSM handovers the selected UE to a GSM cell.

[0034] In order to make the object, tec...

Abstract

The invention discloses a load balancing method from a time division-synchronization code division multiple access (TD-SCDMA) system to a global system for mobile communication (GSM) system, which comprises the following steps of: when that a TD-SCDMA cell is in congestion is determined, selecting partial online user terminals (UE) supporting the GSM in the TD-SCDMA cell, and switching the selected UE to a GSM cell. Therefore, the load balancing method from the TD-SCDMA system to the GSM system can ensure that UE newly accessing a user terminal successfully accesses a cell in the TD-SCDMA system.

Description

technical field [0001] The invention relates to the technical field of inter-system load balancing, in particular to a load balancing method from a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system to a Global Mobile Communication (GSM) system. Background technique [0002] The Orthogonal Variable Spreading Factor (OVSF) code resource of the cell in the TD-SCDMA system is limited, and the BRU (basic resource unit) is the basic unit of the OVSF code resource. The service to be established by the user terminal (UE) entering the cell needs to occupy a certain amount of OVSF code resources. This makes it impossible for the UE to access the cell. Therefore, in order to maintain the normal working state of the new UE, it is necessary to connect the new UE to the GSM system to realize load balancing from the TD-SCDMA system to the GSM system. [0003] figure 1 It is a working flow chart of the load balancing method from the TD-SCDMA system to the GSM syst...
