Embodiment Construction

[0117] Based on the defects in the existing technology, in order to effectively reduce the interruption time of data transmission when RACH-less handover is adopted, the embodiment of the present invention proposes a method for allocating uplink resources, which is applied to a network system that can realize RACH-less handover middle.

[0118] Such as Figure 5 As shown, it is a schematic flowchart of a method for allocating uplink resources proposed by an embodiment of the present invention, which specifically includes the following steps:

[0119] Step S501, when the user equipment in the network system needs to perform cell handover, the network equipment corresponding to the target cell of the cell handover judges whether the user equipment can perform RACH-less handover.

[0120] If the network device corresponding to the target cell judges that the user equipment can perform RACH-less handover, perform step S502;

[0121] If the network device corresponding to the tar...

Abstract

The invention discloses an uplink resource allocating method and uplink resource allocating equipment. Through a preset rule, network equipment corresponding to a target cell sends a message containing uplink resource allocating information to user equipment, so that the user equipment acquires the uplink resource information, and sends a switching completion message through uplink resources so as to complete cell switching of the user equipment. The method and the equipment can reduce data transmission interruption time caused by random access in the switching process and reduce transmissiondelay.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for allocating uplink resources. Background technique [0002] In the network architecture of the existing Long Term Evolution (LTE) system, such as figure 1 shown. The network-side entity of the LTE system is composed of a Mobility Management Entity (MME) / Service Gateway (S-GW), and an evolution NodeB (eNB). The interface between eNB and eNB is X2 interface, and the interface between MME / S-GW and eNB is S1 interface. [0003] In an LTE network, when a user equipment (User Equipment, UE) moves from one eNB to another, in order to keep ongoing services from being interrupted, it is necessary to perform eNB handover. If there is an X2 connection between eNBs, then the handover process can be completed through the X2 interface; if there is no X2 interface between the eNBs, then the handover process can be completed through the S1 interface.
