The dynamic adjustment is well adapted to the transmission requirements of bursty and high-speed services, and improves the utilization of transmission resources.

Referring to the schematic diagram of the point-to-multipoint microwave transmission structure shown in FIG. 1, the microwave main station and a plurality of microwave slave stations connected to the microwave main station, and a wired transmission network connected to the microwave main station are connected to the wired transmission network. The device may have a GGSN (Gateway General Packet Radio Service Support Node). SGSN (Serving GPRS Support Node), RNC (Radio Network Controller), Serving Gateway GW and MME (Mobility Management Entity), each microwave slave station and one base station Connected; the microwave master station allocates transmission resources for each microwave slave station, each microwave slave station transmits base station services according to the allocated transmission resources, and the microwave master station aggregates base station services from each microwave slave station, and then passes through the wired transmission network after statistical multiplexing.

Referring to FIG. 2, this embodiment provides a method for allocating a transmission resource for microwave transmission. The method is applied to a microwave transmission system, where the system includes a microwave primary station and a microwave slave station that communicates with the microwave master station, and the method includes:

101: The microwave master station acquires resource requirement information of the microwave slave station with which it communicates;

102: The microwave primary station allocates transmission resources for the microwave slave station according to the obtained resource requirement information of the microwave slave station.

The microwave primary station may determine the resource requirement information corresponding to the microwave slave station according to the locally buffered data of the microwave slave station that communicates with the microwave slave station, or the microwave master station receives the transmission resource request message sent by the microwave slave station that communicates with the microwave master station, The resource request information carries the resource requirement information;

The resource requirement information may specifically be a bandwidth required for the microwave slave station to transmit data;

Alternatively, the resource demand information includes: bandwidth and priority information required for the microwave slave to transmit data (eg, gold/silver/bronze card users);

Or, the resource requirement information includes: a bandwidth required by the microwave slave station to transmit data and a quality of service QoS (Quality of Service) information;

Alternatively, the resource requirement information includes: bandwidth required by the microwave slave station to transmit data, priority information, and quality of service QoS information;

The microwave master station can adopt various allocation methods when allocating transmission resources to the microwave slave station according to the resource requirement information of the microwave slave station, for example:

The microwave primary station allocates transmission resources for a plurality of microwave slave stations according to a ratio of bandwidth required for data transmission by a plurality of microwave slave stations;

Or the microwave primary station equally allocates transmission resources to the plurality of microwave slave stations that have determined the resource requirement information;

Or, considering the bandwidth required for the data transmission from the microwave slave station, and the priority information/QoS information of the microwave slave station, allocating transmission resources for the plurality of microwave slave stations; for example, for two microwave slave stations that also require a bandwidth of 5 Mbps, If the QoS of a microwave slave is a high level and the QoS of a microwave slave is a low level, it is preferable to ensure that the transmission resources are allocated to the microwave slaves with a high QoS level. Before the step 101, the method may further include: the microwave primary station may pre-allocate a certain guaranteed transmission resource for each microwave slave station, thereby providing each base station with the minimum transmission resource required to ensure base station signaling and real-time voice service transmission. In this way, when the transmission resource needs to be allocated dynamically, the microwave primary station will ensure the remaining transmission resources except the transmission resource as the dynamic transmission resource, and then allocate the dynamic transmission resource to each microwave slave according to the obtained resource requirement information of the microwave slave station.

Further, in the initial stage of network deployment, the remaining transmission resources other than the above guaranteed transmission resources may also be equally distributed to the respective microwave slave stations. In the subsequent communication process, when the microwave primary station allocates transmission resources, the remaining transmission resources other than the above-mentioned guaranteed transmission resources may be reallocated according to the proportion of each microwave slave station resource requirement information.

Of course, in actual applications, the guaranteed transmission resources may not be allocated in advance, but all the transmission resources are used as dynamic transmission resources, and the transmission resources are allocated to the respective microwave slave stations according to the resource requirement information of each microwave slave station.

After the step 102, the method further includes: the microwave primary station transmitting the allocation information of the transmission resource to the microwave slave station;

The microwave slave station receives the allocation information of the transmission resource, and transmits the allocation information of the transmission resource to the base station;

The base station, the microwave slave station, and the microwave master station transmit data according to the allocation information of the transmission resources.

The above-mentioned transmission resource allocation method for microwave transmission is suitable for microwave transmission, especially point-to-multipoint microwave transmission. Accordingly, the functions of the microwave master station and the microwave slave station are as follows:

A microwave master station is a device with aggregation function for aggregating and distributing received data;

A microwave slave station is a device with a forwarding device function for forwarding received data.

In this embodiment, the resource requirement information corresponding to the microwave slave station is obtained, and the transmission resource is allocated according to the resource requirement information, thereby realizing dynamic allocation of the transmission resource. In the face of bursty, high-speed services, more transmission resources can be allocated than fixed transmission resources, the utilization of transmission resources is improved, and the data transmission requirements of wireless network broadband are satisfied.

The above describes the transmission resource allocation method of microwave transmission. The following describes the different methods corresponding to the resource demand information of the microwave slave station that the microwave master station obtains, and elaborates how the microwave master station dynamically allocates the transmission according to the acquired resource demand information. Resources. Example 2

When the microwave primary station allocates dynamic transmission resources, the dynamic transmission resources may be evenly distributed to the microwave slave stations (that is, the microwave slave stations whose data to be sent exceeds a preset threshold), for example, the dynamic transmission resource has a remaining bandwidth of 10 Mbps as an example. If there are two microwave slave stations whose data to be sent exceeds the preset threshold, the bandwidth of each of the two microwave slave stations will be increased by 5 Mbps; or according to the amount of data buffered, according to a certain plan, such as according to the determined resource requirements. The proportion of information is allocated to the transmission resource, that is, the larger the amount of data to be transmitted, the more newly allocated transmission resources.
