Problems solved by technology

[0010] When the BS is paging the MS, it does not know the specific location information of each paged MS, let alone the channel conditions of each MS, so the performance of sending paging messages cannot be well guaranteed. It may cause that some paging cannot be received correctly in time, especially for some high-priority paged users. When paging cannot be received correctly, the paging performance of these high-priority users cannot be guaranteed
Therefore, the existing paging mechanism may reduce the paging success rate, increase the paging delay, and affect the user's QoS (Quality of Service, service quality) experience

Embodiment 1

[0040] This embodiment takes the 802.16e system as an example, and describes that the BS encodes the paging message into multiple HARQ (Hybrid Automatic Repeat reQuest, Hybrid Automatic Repeat reQuest) data subpackets, and assigns them to multiple frames to realize The process of paging the MS.

[0041] see figure 2 , is a schematic flowchart of Embodiment 1 of the present invention. When the BS needs to send downlink data to the MS in idle mode, the BS needs to wake up the MS through paging. The BS wakes up these MSs by broadcasting a paging message in the paging cycle of the MSs, and the process includes steps:

[0042] Step 201, when the BS decides to send a paging message to the MS, it encodes the paging information to form multiple HARQ data subpackets, and allocates transmission resources for these HARQ data subpackets.

[0043] The BS can send one or more HARQ data subpackets of the paging message in one MS paging cycle, especially when the BS finds that the user pr...

Embodiment 2

[0054] This embodiment takes the 802.16e system as an example, and describes that the BS encodes a paging message into multiple HARQ data subpackets, and assigns them to multiple different time and frequency resources in a certain frame, and paging the MS process.

[0055] When the BS needs to send downlink data to the MS in idle mode, the BS needs to wake up the MS through paging. The BS wakes up these MSs by broadcasting a paging message in the paging cycle of the MSs, and the process includes steps:

[0056] Step 301, when the BS decides to send a paging message to the MS, it encodes the paging information to form multiple HARQ data subpackets, and allocates transmission resources for these HARQ data subpackets.

[0057] The BS can send one or more HARQ data subpackets of the paging message in one MS paging cycle, especially when the BS finds that the user priority of the paged MS is high, it can send two or more HARQ data subpacket.

[0058] In a paging cycle, since mul...

Embodiment 3

[0068] This embodiment takes the 802.16e system as an example, and describes that the BS encodes the paging message into a HARQ data subpacket, and sends it in the downlink subframe negotiated with the MS, and the MS receives the paging message in the negotiated downlink subframe the process of.

[0069] see Figure 5 , is a schematic flow chart of Embodiment 3 of the present invention. When the BS needs to send downlink data to the MS in idle mode, the BS needs to wake up the MS through paging. The BS wakes up these MSs by broadcasting a paging message in the paging cycle of the MSs, and the process includes steps:

[0070]Step 501, when the BS decides to send a paging message to the MS, it encodes the paging information to form multiple HARQ data subpackets, and the HARQ data subpackets indicate that the data packets are paging message data and carry the target MS's Identification information. The BS allocates transmission resources for these HARQ data subpackets accordi...

Abstract

The invention discloses a calling method in wireless communications system and a device hereof; the method of the invention comprises the following steps that a base station codes the calling information of object terminal into at least an HARQ data sub-package; the base station dispatches the HARQ data sub-package to at least one frame in the calling period of the object terminal for broadcasting according to the distributed resources of the HARQ data sub-package or the resources of the object terminal negotiation. By adopting the invention, the performance for receiving call information and the call completion rate could be increased; at the same time, call delay could be reduced and the service quality for users could be promoted.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a paging method and device in a wireless communication system. Background technique [0002] WiMAX (Worldwide Interoperability for Microwave Access) is an alliance jointly established by major broadband wireless access equipment manufacturers and chip manufacturers in 2001. It was initially promoted by IT equipment manufacturers and chip manufacturers. Its standardization organization is IEEE (Institute of Electrical and Electronics Engineers). The WiMAX air interface standard adopts IEEE 802.16. 802.16 is a metropolitan area network standard for broadband wireless access and packet switching. Among them, 802.16d (802.16-2004) is suitable for fixed wireless access, and 802.16e (802.16-2005) is suitable for certain Wireless access for mobility. The air interface standard defined by 802.16e of WiMAX adopts advanced OFDM (Orthogonal Frequency Division Multiplexing) te...
