Embodiment 1

[0041] In this embodiment, the RELOCATION COMMOND message sent by the core network device to the RNC based on the Iu interface is extended to carry relocation type information, so that the RNC can identify the type of this relocation according to the information, that is, identify the target network, and then Ensure correct processing of the relocation procedure on the RNC side. Wherein, the relocation type includes: UTRAN->UTRAN, UTRAN->GSM, UTRAN->LTE, that is, the relocation type indicates which target network to switch from UTRAN to.

[0042] In specific implementation, a Handover Type IE (handover type information element) can be added in the 3GPP 25.413 protocol RELOCATION COMMOND message, and the RNC can clearly know which network (such as LTE, GSM or UTRAN).

[0043] Table 1 and Table 2 show the format of an extended RELOCATION COMMOND message according to an embodiment of the present invention.

Embodiment 2

[0061] Since the RNC knows the target system at the beginning of the relocation process (that is, knows which network to tangent to), the RNC can locally maintain identification information used to identify the relocation type or target system type, such as recording which network the RNC is tangent to. Network (such as LTE, GSM or UTRAN), so that after receiving the RELOCATION COMMOND message sent by the core network, the RNC can identify the type of this relocation according to the identification information, that is, identify the target network, and then ensure the relocation process Correct handling on the RNC side.

[0062] Since the RELOCATION COMMOND message and the RELOCATION REQUIRED message are used in pairs, in specific implementation, the RNC may record the relocation type or For the target network, after the RNC receives the RELOCATION COMMOND message returned by the core network equipment, it reads the relocation type identifier of the current relocation process ...

Abstract

The invention discloses a repositioning method and a repositioning device. According to one method, repositioning type information is carried in a repositioning instruction sent to a source radio network control device by a core network, so that a radio network controller can know a target network type according to the repositioning type information, and a terminal is triggered to switch to a corresponding target network, thereby ensuring correct treatment of a repositioning process on a source RNC (Radio Network Control) side. According to the other method, when a repositioning request is sent to the core network by a radio network control device, the repositioning type information during the current repositioning process is recorded by a identifier corresponding to the terminal, and after the repositioning instruction is received from the core network, the repositioning type information during the repositioning process correspondingly recorded by the identifier of the terminal is obtained according to the target terminal of the repositioning instruction, so that the target network type is known by the radio network control device and the terminal is triggered to switch to the corresponding target network, thereby ensuring the correct treatment of the repositioning process on the source RNC side.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a relocation method and equipment thereof. Background technique [0002] LTE (Long Term Evolution, Long Term Evolution) technical standard is the development trend of mobile communication technology. The realization of interoperability between TD (Time Division, Time Division) system and LTE system is of great significance to the development of the mobile communication market. [0003] Currently RNC (Radio Network Controller, radio network controller) to GSM (Global System of Mobile communication, Global System for Mobile Communications) / LTE / UTRAN (Universal Mobile Telecommunications System Terrestrial Radio Access Network, Universal Mobile Communications System Terrestrial Radio Access Network) The message interaction of the Iu interface during relocation is as follows: figure 1 As shown, wherein, the Iu interface is the interface between the RNC and the core netwo...
