Terminal relocation method, device and system

Abstract

The invention relates to the wireless communication field and discloses a repositioning method of terminals, equipment and a system of a terminal to avoid the serious idling of the Node B plus of an HSPA plus network. In the invention, after the completion of the CS service of the terminal, if the terminal still uses the PS service, the SRNC of the terminal is repositioned from the RNC of a traditional network to the Node B plus of the HSPA plus network. Before repositioning, a decision on whether to reposition can be made on a plurality of grounds, including that whether the SRNC of the terminal is repositioned from the Node B plus of the HSPA plus network to the RNC of the traditional network, as well as the loading information of the RNC of the traditional network and / or the loading information of the Node B plus of the HSPA plus network.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to terminal relocation technology. Background technique [0002] In 2006, the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as "3GPP") passed the High Speed ​​Data Access (High Speed ​​Packet Access, referred to as "HSPA") evolution research project, and the evolved network architecture of HSPA (referred to as HSPA+ network) is based on the packet domain (PS) service, which will provide high bit rate user rate and shorter call delay for PS service; for the circuit of the current third generation mobile communication (The Third Generation, referred to as "3G") system Domain (CS) services will no longer be optimized. [0003] In the HSPA+ network, all functions of the radio network controller (Radio Network Controller, "RNC" for short) of the existing 3G system are placed on the evolved HSPA base station node (NodeB+). On the connection to ...

Problems solved by technology

[0015] The inventors of the present invention have found that as time goes by, if a large number of terminals experience a process of accessing PS services first and then CS services, and the CS services end first, the PS services of these terminals will be concentrated through the RNC of the traditional network Access to the core network, such as Figure 10 As shown, the RNC function of NodeB+ will be weakened

[0016] In addition, in the above two deployment scenarios, while the NodeB+ (or the RNC function of the NodeB+) is idle, the business volume of the traditional RNC will increase greatly, and the access load cannot be shared between the NodeB+ and the RNC of the traditional network.

[0017] Moreover, for terminals that support HSPA+ features (such as high bandwidth and low delay), the PS service performance obtained by these terminals may not meet the subscription requirements of users because the RNC of the traditional network cannot provide the required performance or quality of service.
