Method for implementing calling using high-speed packet access reinforcement in time division duplex system

Abstract

A method for realizing paging via HSPA in TDD system, comprising: configuring PMRO of a plurality of UE in the TDD system, notifying the PMRO to node B, and using H-RNTI relating to a plurality of different paging sub-channels to respectively identify each paging sub-channel, wherein setting number of wireless frame occupied by each paging sub-channel in the a plurality of paging sub-channels as single or multiple; the RNC configures channel informational correlation between the PICH and the HS-SCCH, number of wireless frame occupied by each paging sub-channel; the RNC pages UE in predetermined state, calculates paging occasion of UE in this state and sending occasion of paging group of the HS-SCCH, and maps the PCCH to data frame of the HS-DSCH to the node B; the node B sends PI in the PICH, and sends HS-DSCH control information on HS-SCCH of this paging group, and sends paging message on the HS-PDSCH; the UE carries out relevant process after receiving the PI, and receives HS-PDSCH control information of the HS-SCCH, and decodes according to the indicated HS-PDSCH, receives paging message from the HS-PDSCH.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a method for realizing paging by using High Speed ​​Packet Accessplus (HSPA+ for short) in a Time Division Duplex (TDD) system. Background technique [0002] With the continuous development of the third-generation mobile communication, HSPA technology is introduced on the basis of high-speed downlink physical access (HSDPA) and high-speed uplink physical access (HSUPA), frequency division duplex (FDD) system supports user equipment ( User Equipment (referred to as UE) is in idle (IDLE) state, cell_paging channel (CELL_PCH) state, and UTRAN (public terrestrial radio access network) registration area_paging channel (URA_PCH) state is in discontinuous reception cycle (DRX ) to detect a paging indicator channel (Paging Indicator Channel, PICH). [0003] In the actual processing process, when the UE detects a Page Indicator (PI for short), if the UE has a dedicated high...

Problems solved by technology

[0005] However, for the UE paging reception mode without dedicated H-RNTI, if the UE being paged in the cell hears PI, each UE must receive the HS-PDSCH at the same time at a fixed offset, where one RRC signaling The paging type 1 message contains at most 8 paging records, and the number of PI carried by PICH is greater than 8 (it can be 18, 36, 72 or 144 according to the high-level configuration), which will cause many UEs to receive redundant paging messages processing, which obviously does not help the UE to save energy

[0006] So far, there is still a lack of effective solutions to the above problems
