Problems solved by technology

That is to say, when each node allocates the bandwidth, the data transmission time from MS to MMR-BS is greatly reduced, but the reduction of transmission time is at the expense of more waiting time spent by MMR-BS and each RS, so, from The whole process from allocating bandwidth to transferring data is still relatively long
At the same time, because the MMR-BS and each RS allocate bandwidth for the next-level nodes in advance, the link conditions may also change during the waiting period for data transmission, and the allocated bandwidth cannot adapt to the changed link conditions, which will Affects the transfer of data

Embodiment 1

[0056] The multi-hop network in this embodiment includes MMR-BS, RS1-RSn, wherein RSn is the synchronization station of MS; in addition, this embodiment adopts the first type of resource scheduling method, and the scheduling management messages involved are distributed scheduling Manage messages.

[0057] Figure 4 is a schematic diagram of message flow in this embodiment, such as Figure 4 As shown, this embodiment includes the following steps:

[0058] Step 401: The MMR-BS generates a scheduling management message according to system resources and service requirements, and sends the scheduling management message to RS1.

[0059] The system resources and business requirements can be information such as system resource conditions, path information, time delay of each link, and service quality (Qos); the scheduling management message includes bandwidth grant time and bandwidth size, and the bandwidth grant time can be MMR - The time when the BS provides bandwidth to RS1 may ...

Embodiment 2

[0086] Same as Embodiment 1, the multi-hop network of this embodiment also includes MMR-BSs, RS1-RSn, wherein RSn is a synchronization station of MS; in addition, this embodiment adopts the second type of resource scheduling method.

[0087] Figure 5 is a schematic diagram of message flow in this embodiment. Such as Figure 5 As shown, this embodiment includes the following steps:

[0088] Step 501: MS sends a bandwidth request to RSn.

[0089] Step 502: RSn sends a bandwidth request to its superior node.

[0090] Step 503: RSn will give the MS the bandwidth allocated for the MS.

[0091] Step 504: RSn obtains the given bandwidth from its superior node.

[0092] Step 505: MS transmits data to RSn through the bandwidth obtained from RSn bandwidth provision.

[0093] Step 506: RSn transmits the received data to the upper-level node through the bandwidth obtained from the bandwidth provision of its own upper-level node.

[0094] Since there are multiple RSs between the MM...

Embodiment 3

[0104] Same as Embodiment 1, the multi-hop network of this embodiment also includes MMR-BS, RS1-RSn, wherein RSn is the synchronization station of MS; in addition, this embodiment adopts the third type of resource scheduling method, that is, adopts In the resource scheduling method of polling time control or the resource scheduling method of giving time control to bandwidth, the scheduling management messages involved are centralized scheduling management messages.

[0105] Figure 6 It is a schematic diagram of the message flow using the polling time control resource scheduling method. Such as Figure 6 As shown, the resource scheduling method for polling time control includes the following steps:

[0106] Step 601: The MMR-BS generates a scheduling management message according to system resources and service requirements, and sends the scheduling management message to RS1.

[0107] The scheduling management message described here is similar to the scheduling management me...

Abstract

The invention provides a resource dispatching method and a system based on a wireless system, applied to a multi-hop network, and the specific realization method is: a bandwidth is given to MS by a mobile terminal MS synchronous station, and data are transmitted to the synchronous station of MS through the acquired bandwidth by MS; data is transmitted to an upper node through the bandwidth given by the upper node from each level of nodes between MS and MMR-BS supporting a mobile multi-hop relay station, after a bandwidth given by the upper node is acquired between a lower node given by the bandwidth and the data received from the lower node and data of the lower node are received. The invention has the advantages that the application of the scheme can assure the acquirement of the bandwidth before receiving the transmitted data from the lower node; the space between the acquired bandwidth and the received transmission data is relatively small; not only can the whole data transmission time be effectively compressed, but also the distributed bandwidth is in line with the real-time condition of a link of the network; a problem of disabled bandwidth distribution can be effectively avoided.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a resource scheduling method and system of a wireless system. Background technique [0002] In a wireless communication system, according to the communication path between the source and the sink, the network structure can be a network structure in which the source and the sink communicate directly, such as a cellular network; it can also be a communication between the source and the sink through the forwarding of a relay node At present, network structures such as relay network and grid network all belong to this type. [0003] Since the source and sink can communicate directly, the cellular network can also be called a single-hop network, and the network that needs to be forwarded by a relay node is collectively called a multi-hop network. [0004] Among them, the single-hop network has only two endpoints, the base station (BS) and the mobile terminal (MS). When all...
