Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] In the EUTRAN system, the lower layer (RLC layer or MAC layer) is rebuilt (when the UE accesses or initiates a call or handover or the protocol layer is wrong, the UE initiates RRC connection establishment and connection reconfiguration, triggering the RLC layer and MAC layer to perform Protocol layer reconstruction), high layer (PDCP layer or RRC layer) or low layer receives suspension indication, or data link (including: one or more radio bearers between PD...

Abstract

The embodiment of the invention discloses a method and equipment of data suspension, which relates to the technical field of communication and carries out effective data suspension in an EUTRAN system. The method comprises the following steps: a lower layer carries out reconstruction; after reconstruction is completed, a high layer transmits data to the lower layer; and after the data suspension is triggered, the high layer carries out suspension on the data of a data link or indicates the lower layer to carry out suspension on the data of the data link. The technical scheme provided by the embodiment of the invention can be widely applied in the EUTRAN system, carries out data suspension according to the functional characteristics of different protocol layers, and effectively controls thetransmission of the data.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and equipment for data suspension in an EUTRAN (Evolved UMTS Terrestrial Radio Access Network, Evolved UMTS Terrestrial Radio Access Network) system. Background technique [0002] In the EUTRAN system, a UE (User Equipment, user equipment) interacts with a NodeB through a Uu radio interface, and the Uu radio interface is divided into a physical layer, a data link layer and a network layer. The data link layer further includes the following sublayers: Medium Access Control (MAC, Medium Access Control), Radio Link Control (RLC, Radio Link Control) and Packet Data Convergence Protocol (PDCP, Packet Data Convergence Protocol). [0003] Each sub-layer interface of the data link layer has a SAP (Service Access Point, service access point). The SAP between the physical layer and the MAC layer provides a transmission channel, and the SAP between the MAC layer and ...
