Problems solved by technology

However, the Iu connection must be used during the relocation process of the serving RNC. It can be seen that if the UE does not have an Iu connection when receiving MBMS services, the UE may not be able to perform serving RNC relocation because there is no Iu connection, thus affecting the time when the UE receives MBMS services. continuity

Embodiment Construction

[0052] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation of the present invention in detail in conjunction with the accompanying drawings.

[0053] The first embodiment of the present invention relates to a serving RNC migration method. In this embodiment, there is no corresponding Iu connection between the source RNC and the CN, and the connection corresponds to the UE whose serving RNC is to be migrated. The specific process is as figure 2 shown.

[0054] In step 210, when the UE's serving RNC needs to relocate, the source RNC sends a "relocation required" message to the CN, which is a connectionless message. The "relocation required" message contains "target RNC identification", "source RNC to target RNC transparent container" and "UE identification" information element, wherein the "source RNC to target RNC transparent container" information element contains the RAB of ...

Abstract

The invention relates to the wireless communication field, and discloses a migration method serving a radio network controller and the radio network controller, which ensures UE to carry out service RNC migration when receiving MBMS services. When no Iu connection exists between the source RNC and CN, the migration of the service RNC can be carried out by connectionless message interaction; connection can also be established in advance and then is released after the migration is finished; the message interaction required by the service RNC migration can also be carried out by an Iur interface between the source RNC and a target RNC.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a migration technology of a serving radio network controller (RadioNetwork Controller, "RNC" for short). Background technique [0002] With the development of science and technology, communication has gone through the first generation and the second generation, and entered the period of the third generation. The first-generation mobile communication system is an analog cellular mobile communication system, from the mid-1970s to the mid-1980s; the second-generation mobile communication system is for the purpose of transmitting voice and low-speed data services, so it is also called narrowband Digital communication system; it has been developed to the third generation of mobile communication system, and the goal is broadband multimedia communication. Wideband Code Division Multiple Access (WCDMA for short) is currently one of the three major third generation mobile co...
