Embodiment 1

[0048] In this embodiment, the admission decision criterion sent by the source base station is: if there are N bearers in the handover terminal, and only if a candidate cell can accept all of the N bearers, the candidate cell can be used as the target cell. The specific process is as follows:

[0049] Step S01: the source base station sends a handover request message to the candidate base station controlling the candidate target cell, the handover request message includes the admission decision criterion and a list of N bearer information of the handover terminal;

[0050]Step S02: After receiving the handover request message, the candidate base station judges whether all of the N bearers can be accepted according to the currently available resources and the information of the N bearers; The source base station returns a handover request confirmation message; otherwise, generates an acceptance judgment failure result, and returns a handover preparation failure message to the s...

Embodiment 2

[0053] In this embodiment, the admission decision criterion sent by the source base station is: if there are N bearers in the handover terminal, and if a candidate cell can accept the M bearers specified in the N bearers, the candidate cell can be used as the target cell . The specific process is as follows:

[0054] Step S11: The source base station sends a handover request message to the candidate base station controlling the candidate target cell, the handover request message includes the admission decision criterion, the first list including the N bearer information of the handover terminal, and the M designated a second list of carried identification information;

[0055] Step S12: After receiving the handover request message, the candidate base station searches the first list for the bearer information corresponding to each bearer identifier in the second list, and then judges whether all of them can be accepted according to the bearer information and currently availabl...

Embodiment 3

[0059] In this embodiment, the admission decision criterion sent by the source base station is: if there are N bearers in the handover terminal, and only if a candidate cell can accept a specified number of bearers, the candidate cell can be used as the target cell. The specific process is as follows:

[0060] Step S21: the source base station sends a handover request message to the candidate base station controlling the candidate target cell, the handover request message includes the admission decision criterion and a list of N bearer information of the handover terminal;

[0061] Step S22: After receiving the handover request message, the candidate base station judges whether all the specified number of bearers in the bearers to be admitted can be accepted according to the currently available resources, and if so, generates a success result of the admission decision, and sends the result to the source base station Returning a handover request confirmation message; otherwise,...

Abstract

The embodiment of the invention discloses a method for admitting judgment during a switching process. The method comprises the following steps: a candidate base station receives an admission request which contains admission judgment criteria and bearer information to be admitted by a candidate cell and is sent by a source base station; carries out admission judgment on a bearer according to the admission judgment criteria to generate an admission judgment result; and returns a switching request confirmation message or a switching preparation failure message to the source base station according to the admission judgment result. The embodiment of the invention further discloses a system for admitting judgment during the switching process and a device thereof. The method, the system and the device can help greatly improve flexibility of admission judgment during the switching process and nicely meet the experience requirements of users.

Description

technical field [0001] The present invention relates to the field of wireless transmission, in particular to a method, system and device for admitting decision in the handover process. Background technique [0002] In the Long Term Evolution (LTE) system, the handover process is completely controlled by the network side, and the target cell for handover is completely determined by the network side. There are two possible processes as follows: [0003] The first type, such as Figure 1A As shown, it specifically includes the following steps: [0004] Step 101: controlling the base station of the source cell (source base station) to generate the range of candidate cells; [0005] Step 102: the source base station selects a candidate cell (candidate cell 1), and sends a handover request (Handover Request) message to the base station (candidate base station 1) controlling the candidate cell 1; [0006] Step 103: Candidate base station 1 returns a Handover Request Acknowledge (...
