Problems solved by technology

[0006] In the process of realizing the present invention, the inventor found that the prior art has at least the following problems: when the UE is redirected to a certain RAT or frequency according to the needs, the UE may be redirected according to the cell before the RAT or frequency initiates normal services. Reselection priority reselects back to the original cell, so that normal services cannot be initiated on this RAT or frequency; and when the UE migrates to another RAT due to business-driven reasons, it may also stay on forever according to the cell reselection priority In this RAT, the user equipment cannot normally initiate services in other systems

Embodiment 3

[0053] Embodiment 3 is a user equipment 310, such as image 3 shown, including:

[0054] A receiving unit 311, configured to receive the migration indication information sent by the source system where the user equipment is located;

[0055] a redirecting unit 312, configured to redirect to a target frequency or a cell in the target wireless access system;

[0056] The radio resource connection establishment and cell reselection unit 313 is configured to perform the radio resource connection establishment process and the cell reselection process after redirection, and before the radio resource connection establishment succeeds or fails according to the relocation instruction information received by the receiving unit, And / or, before the timer expires, the user equipment is not reselected back to the source system or the cell in the source frequency.

[0057] The radio resource connection establishment and cell reselection unit 313 may include:

[0058] The first execution m...

Embodiment 4

[0063] Embodiment 4 is a user equipment 410, such as Figure 4 shown, including:

[0064] a receiving unit 411, configured to receive the migration indication information sent by the source system where the user equipment is located;

[0065] a redirecting unit 412, configured to redirect to a target frequency or a cell in the target wireless access system;

[0066] The cell reselection unit 413 is configured to perform a cell reselection process after redirection, and not to reselect the user equipment back to the source system or the source system before the timer expires according to the relocation indication information received by the receiving unit. cell in the source frequency.

[0067] The cell reselection unit 413 may include:

[0068] a first execution module, configured to perform a cell reselection process after redirection, and ignore the cell reselection priority of the source system or source frequency before the timer expires according to the relocation inst...

Embodiment 6a

[0084] Example 6a, taking switching from the E-UTRAN packet domain to UTRAN as an example, such as Figure 6a The specific process is as follows:

[0085] 601a) establishing an RRC signaling connection between the UE and the evolved base station eNB;

[0086] 602a) the eNB instructs the UE to perform corresponding measurements through a measurement control message;

[0087] 603a) The UE performs inter-system measurement according to the eNB instruction;

[0088] 604a) UE sends a measurement report to eNB;

[0089] 605a) eNB, radio network controller RNC, and mobility management entity MME prepare for packet switching;

[0090] 606a) The eNB sends a move command to the UE, instructing the UE to perform handover, the move command also carries relocation indication information, and the indication information is used to instruct the user equipment after the service is completed and / or after the timer expires , and then migrate from UTRAN to a specified system, taking E-UTRAN a...

Abstract

The invention discloses a method and a device for processing migration of user equipment, wherein the method comprises the following steps: receiving migration instruction information sent by a sourcesystem to which the user equipment belongs; redirecting the user equipment to a target frequency or a cell in a target wireless access system; and performing the process of establishing wireless resource connection and the process of reselecting the cell after the user equipment is redirected, and according to the migration instruction information, not reselecting the user equipment back into thecell in the source system or a source frequency. The method and the device can avoid that the user equipment cannot initiate a service normally because of the reselection of the priority of the cell.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method and apparatus for processing migration of user equipment. Background technique [0002] With the development of mobile communication technology, more and more mobile communication systems have appeared, such as Global System For Mobile Communication (GSM), Wideband Code Division Multiple Access (WCDMA), Code Division Multiple Access 2000 (Code Division Multiple Access 2000, CDMA2000), Time Division Synchronous Code Division Multiple Access (Time Division-Synchronous CDMA, TD-SCDMA), Long Term Evolution (Long Term Evolution, LTE) and Global Microwave Interconnection Access System ( World Interoperability for Microwave Access, WIMAX) and more. [0003] In a communication system, such as an LTE system, during the redirection process, redirection information may be sent to the terminal through a radio resource control (Radio Resource Control, RRC) conn...
