Embodiment 1

[0070] In this embodiment, when a UE in a two-path macro-diversity state (that is, with two RLs) establishes a service, it uses the link deletion method when the R99RL reconfiguration fails in the embodiment of the present invention to illustrate the process of establishing a service. The embodiment is only for illustration, and the application scenarios of the present invention include but not limited to this embodiment. image 3 Shown is the R99RL deletion method in the business establishment process, and this method comprises the following steps (step S302-step S314):

[0071] In step S302, the RNC configures the R99 co-frequency adjacent cell, so that the UE establishes two-path R99 macro-diversity, and then initiates a service establishment procedure. The R99 same-frequency neighboring cell may be an intra-RNC co-frequency neighboring cell, or may be a cross-Iur co-frequency neighboring cell. This embodiment describes in detail the situation that the R99 same-frequency ne...

Embodiment 2

[0081] In this embodiment, when a UE in a two-path macro-diversity state (that is, with two RLs) establishes a service, the process of establishing a service by using the link deletion method when the HSPA non-serving RL reconfiguration fails in the present invention is described. Of course This embodiment is only an example, and the application scenarios of the present invention include but are not limited to this embodiment. Figure 4 Shown is the flow chart of the HSPA non-serving RL deletion method in the business establishment process, and this method comprises the following steps (step S402-step S414):

[0082] In step S402, the RNC configures HSPA co-frequency adjacent cells, so that the UE establishes two-path HSPA macro-diversity, and then initiates a service establishment procedure. The HSPA same-frequency neighboring cell may be an intra-RNC co-frequency neighboring cell, or may be a cross-Iur co-frequency neighboring cell. This embodiment describes in detail the si...

Embodiment 3

[0092] In this embodiment, when a UE in a two-path macro-diversity state (that is, with two RLs) establishes a service, the process of establishing a service by using the link deletion method when the HSPA service RL reconfiguration fails in the present invention is described. The embodiment is only for illustration, and the application scenarios of the present invention include but not limited to this embodiment. Figure 5 Shown is the flow chart of the HSPA service RL deletion method in the service establishment process, and the method includes the following steps (step S502-step S514):

[0093] In step S502, the RNC configures HSPA co-frequency adjacent cells, so that the UE establishes two-path HSPA macro-diversity, and then initiates a service establishment process. The HSPA same-frequency neighboring cell may be an intra-RNC co-frequency neighboring cell, or may be a cross-Iur co-frequency neighboring cell. This embodiment describes in detail the situation that the HSPA ...

Abstract

The invention discloses a method, a device and a system for deleting links. The method comprises that a radio network controller (RNC) detects whether a current situation meets following conditions: user equipment (UE) is in a macrodiversity state, at least one radio link (RL) corresponding to the UE fails in reconfiguration, and at least one RL succeeds in reconfiguration; if the conditions are met, the RNC indicates that the UE delete the RL failing in reconfiguration; and the RNC informs a base station corresponding to the RL failing in reconfiguration to delete the failed RL after receiving response information completed by a business processing flow which is returned by the UE. By means of the method, the device and the system for deleting links, the business processing flow is optimized, the processing time delay is shortened, the air interface interaction is reduced, and air interface resources are saved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a link deletion method, device and system. Background technique [0002] In a Wideband Code Division Multiple Access (WCDMA) system, a user can use multiple codewords on a certain carrier frequency to communicate simultaneously, and these codewords belong to different cells. A state in which multiple radio links (Radio Link, RL for short) links exist between the user and the network is called a macro-diversity state. The macro-diversity technology enables the UE to obtain good radio quality from different cells when it moves between cells. When the UE is in the macro-diversity state and the core network (Core Network, CN for short) initiates the service establishment process, the entire service establishment may fail due to the failure of RL reconfiguration of a certain leg. There are many reasons for RL reconfiguration failure, including code resource congestion, transmission...
