Description

METHOD, SYSTEM AND DEVICE FOR CONFIGURING SEMI-PERSISTENT SCHEDULING RESOURCE}

TECHNICAL FIELD The present invention relates to a resource scheduling technique, and more particularly, to a method, system and apparatus for arranging ring scheduling resources, the apparatus including a base station and a radio network controller.

With the development of the system, it will be a trend to provide wireless business support through the IP Multimedia Subsystem (IMS) based on the Internet Protocol. A feature of the wireless service provided by the IMS system is that a user equipment (UE) can simultaneously use a plurality of service services. For example, the UE performs a web browsing task while simultaneously performing a voice task.

The mobile communication system mainly provides a load for a plurality of tasks, and control of the load of tasks is performed by a radio network controller (RNC). The RNC maps one workload to one logical channel, while at the same time the RNC maps at least one logical channel onto one media access layer dedicated data stream (MAC-d stream). In the following description, the work data transmission in the upward direction and the business data transmission in the downward direction will be described.

In the uplink business data, there are a number of tasks in the RNC, each data stream corresponds to one logical channel, and the RNC is logical so that at least one logical channel is mapped to one MAC-d stream. The mapping relationship between the channel and the MAC-d stream is pre-arranged, and the correspondence relationship between the MAC-d stream and the priority queue is further arranged such that another MAC-d stream corresponds to at least one priority queue. The correspondence between the arranged MAC-d stream and the priority queue is informed to the base station Node B. When proceeding with the downlink transmission, the RNC maps the data stream on at least one logical channel to one MAC-d stream and transmits it to Node B via the MAC-d stream, and Node B sends the RNC via the MAC-d stream. After receiving the transmitted data stream, the data buffer of the MAC-d stream is buffered in the corresponding priority queue according to the priority of the data stream by the correspondence between the MAC-d stream and the priority queue. The stream consists of a number of data packets. In other words, the data stream carries a plurality of data packets. Node B detects the characteristics of each data packet loaded on the data stream buffered in each priority queue, and schedules resources to be used when transmitting data between Node B and UE for each data packet. Node B sends a data packet to the UE through the scheduled resource. The nature of the data packet includes the size of the data packet.

In the downward direction, one MAC-d stream may be mapped to different priority queues. Node B schedules according to the priority of different data packets loaded on the same MAC-d stream. Here, different logical channels mapped to the same MAC-d stream may be viewed as "sub streams" from corresponding same MAC-d streams. Since these substreams may have different priorities, the substreams may be mapped to different priority queues.

In the uplink task data, when there are a plurality of tasks in the terminal as well, the data stream of each task corresponds to one UE-side logical channel, and the RNC pre-arranges the mapping relationship between the logical channel and the MAC-d stream. In addition, a plurality of logical channels corresponding to a plurality of tasks are also mapped onto at least one MAC-d stream, and the RNC informs the base station Node B of the mapping relationship between the arranged MAC-d stream and the logical channel. When the uplink transmission is performed, the UE loads at least one logical channel with data streams corresponding to a plurality of tasks and transmits the same to Node B, and then Node B transmits at least one data stream according to the mapping relationship between the MAC-d stream and the logical channel. The data stream loaded on the logical channel is mapped to one MAC-d stream and transmitted to the RNC through the MAC-d stream.

In the ascending direction, Node B receives the ascending business data stream, transmits it directly to the RNC through the MAC-d stream, buffers the data stream back to the priority queue, and does not wait for the transmission process. No longer does the concept of priority queues appear in the process. Node B also detects the characteristics of each data packet sent from the received UE and schedules resources for the data packet. The UE transmits each data packet to the Node B through the scheduled resource. The nature of the data packet includes the data packet size.

The interrelationship between logical channels, MAC-d streams and priority queues in mobile communication systems has been introduced above. The following describes the ring scheduling method and a problem present in a high speed packet access (HSPA) system in a mobile communication system.

Currently, ring scheduling, which is discussed in the Continuous Packet Connectivity (CPC) feature of the HSPA + system, is a kind of scheduling method. The ring scheduling predicts according to the characteristics of the downlink data stream to be transmitted by Node B or the characteristics of the upstream data stream sent from the receiving terminal, thereby pre-distributing resources for transmission of the data stream for a subsequent long time. Scheduling method. A resource arranged in a ring scheduling method is called a ring scheduling resource. The characteristic of the data stream includes the size and time of the data packet loaded in the transmitted data stream, and when the characteristic of the data stream changes within a certain time, the Node B relocates the scheduling scheduling in the ring for the UE. In this way, by using a method of scheduling resources according to the characteristics of the data stream, it is possible to arrange the ring scheduling resources in advance for transmission of the data stream in a subsequent long time, and according to the characteristics of each data packet as in the previous method. There is no need to arrange resources for the transmission of data packets in real time, simplifying the operation.

In the current system, when Node B performs business services, some tasks should be ring-scheduled, but some tasks are not suitable for ring-scheduling. The RNC determines whether a service is suitable for serving the service in a ring scheduling manner according to the Quality of Service (QOS) information of the work exchanged between the RNC and the core network. However, in the prior art, Node B cannot know which task's data stream should use ring scheduling. In other words, it does not accurately detect the characteristics of the data stream that must use the ring scheduling method. Therefore, suitable ring scheduling resources cannot be allocated to the data streams serviced by the ring scheduling scheme, resulting in a failure of the deployment of ring scheduling resources.

An embodiment of the present invention provides a method for arranging a ring scheduling resource capable of realizing an arrangement for a ring scheduling resource.

Embodiments of the present invention provide a system for arranging in-ring scheduling resources that can realize the arrangement for in-band scheduling resources.

2 is a diagram illustrating the structure of an arrangement system of ring scheduling resources in an embodiment of the present invention.

In order to more clearly the objectives, technical solutions and advantages of the present invention, the following further describes the present invention in combination with the embodiments and drawings.

The RNC (Radio Network Controller) determines whether a task is suitable for servicing for the task using a ring scheduling scheme according to QoS information of the task exchanged between the RNC and the core network. In an embodiment of the present invention, the RNC sends a ring scheduling instruction to Node B, which includes information on which task's data stream should be loaded and transmitted in the ring scheduling resource. After receiving the data stream, the Node B determines the data stream to be loaded and transmitted in the ring scheduling resource according to the instruction, and then arranges the ring scheduling resource according to the characteristics of the data stream, The characteristic includes the size of the data packet loaded in the data stream and the time interval of the data packet. This realizes the allocation of scheduling resources in the ring. The deployment described herein includes not only the placement for the initial ring scheduling resource, but also the relocation for subsequent ring scheduling resources.

1 is a flowchart illustrating a method of arranging semi-persistent scheduling (SPS) resources in an embodiment of the present invention. The method includes the following procedure.

[Step 101], Node B receives the ring scheduling instruction sent by the RNC.

The Node B may be directly connected to the RNC controlling the Node B, and may be indirectly connected to the RNC controlling the Node B through other RNCs. Here, the RNC directly connected to the Node B is referred to as a first RNC, and the RNC directly connected to the Node B is referred to as a second RNC.

In the case where Node B is connected to the RNC controlling the Node B through other RNCs, Node B is directly connected to the first RNC, the first RNC is connected to the second RNC, the second RNC and the first RNC Are connected via an interface Iur, and the second RNC generates a ring scheduling instruction and sends the ring scheduling instruction to the first RNC.

Based on the quality of service (QOS) information of the tasks that are exchanged between the RNC and the core network, the RNC determines whether a task is suitable to service the task in a ring scheduling scheme. The ring scheduling method determined by the RNC is to arrange the ring scheduling resource according to the logical channel, the ring scheduling resource according to the MAC-d stream, and the ring scheduling resource according to the priority queue. Method, and the like.

In the downward direction, the ring scheduling instruction may be a ring scheduling instruction arranged according to a MAC-d stream, or the ring scheduling instruction may be a ring scheduling instruction arranged according to a priority queue, or The ring scheduling instruction may be a ring scheduling instruction arranged according to a logical channel.

In the upward direction, the ring scheduling instruction may be a ring scheduling instruction arranged according to a logical channel, or the ring scheduling instruction may be a ring scheduling instruction arranged according to a MAC-d stream. It is determined by the RNC that the scheduling indication is placed according to which object, and is not limited to the manners of arranging according to the above-described logical channel, MAC-d stream, and priority queue.

The ring scheduling instruction may be carried in any interface Iub signal between Node B and the first RNC, the interface Iub signal being a radio link establishment request message, a radio link increase request, a synchronous radio link reconfiguration message, or an asynchronous radio link. Reconfiguration messages. The ring scheduling indication of the present procedure may be a new information element increased in the interface Iub signal between the Node B and the first RNC. For example, it may be a new information element incremented in a radio link establishment request message, a radio link increase request, a synchronous radio link relocation message, or an asynchronous radio link relocation message.

[Step 102] Node B determines a data stream to which ring scheduling resources are to be arranged according to the ring scheduling instructions.

In the downward direction, if the ring scheduling indication is a ring scheduling indication DL arranged according to the MAC-d stream, the indication includes a MAC-d stream identifier and the RNC corresponds to a MAC corresponding to the MAC-d stream identifier. -d Indicates that the data stream sent to Node B through the stream is the data stream to which scheduling resources in the ring are to be located. If the ring scheduling instruction is a ring scheduling instruction placed according to a priority queue, the indication includes a priority queue identifier, Node B receives a data stream sent by the RNC through a MAC-d stream, According to the correspondence relationship between the MAC-d stream stored in the Node B and the priority queue, the data is buffered in the corresponding priority queue, and then the data stream buffered in the priority queue is transmitted to the UE. If the identifier of the priority queue of the extracted data is the identifier of the priority queue included in the indication, the extracted data stream is a data stream to which scheduling resources in the ring are to be arranged. If the ring scheduling instruction is a ring scheduling instruction arranged according to a logical channel, the indication includes a logical channel identifier, and when the data stream is transmitted to a logical channel corresponding to the logical channel identifier, the ring scheduling resource You should use the method. This situation is relatively appropriate for Node B, which supports L2 (Layer2) reinforcement. In this situation, the data stream sent by the RNC and received by the Node B includes the logical channel identifier that sent the data stream of the RNC. After the Node B receives the data stream sent by the RNC, if the logical channel identifier in the data packet loaded in the data stream is the logical channel identifier included in the indication, the data stream is the data to which the scheduling resource in the ring should be placed. It is a stream.

In the upward direction, if the ring scheduling instruction is a ring scheduling instruction arranged according to a logical channel, the logical channel identifier is included in the instruction, and the ring is transmitted when transmitting a data stream on a logical channel corresponding to the logical channel identifier. It indicates that the scheduling method should be used. Node B receives the data stream uploaded by the UE. If the logical channel identifier in the data packet loaded on the data stream is the logical channel identifier included in the indication, the data stream is a data stream in which scheduling scheduling resources are to be arranged. If the ring scheduling instruction is a ring scheduling instruction arranged according to the MAC-d stream, the indication includes a MAC-d stream identifier and replaces a data stream in the MAC-d stream corresponding to the MAC-d stream identifier. When transmitting, it indicates that the ring scheduling scheme should be used. The UE loads data streams corresponding to a plurality of tasks in at least one logical channel, transmits them to Node B, and then Node B performs logical MAC-d streams and logic. According to the mapping relationship between the channels, the data streams loaded on at least one logical channel are mapped in the MAC-d stream. If the identifier of the MAC-d stream is a MAC-d stream identifier included in the indication, the data stream of the MAC-d stream is a data stream to which ring scheduling resources are to be arranged.

[Step 103], Node B allocates ring scheduling resources according to the characteristics of the data stream determined in step 102.

The characteristics of the data stream in this step include the data packet size and data packet time interval loaded in the data stream, and the arrangement not only includes the initial arrangement for the ring scheduling resource, but also the subsequent data stream characteristics. This change also includes relocation of scheduling resources in the ring. In the ascending direction, the change of the data stream characteristic can be determined not only through the data packet received by the Node B, but also through the scheduling information (SI) transmitted by the UE to the Node B. Specifically, if the ring scheduling resource is arranged according to the logical channel, the Node B receives the SI sent from the UE, and the highest priority logical channel ID (HLID) in the SI is the ring scheduling. The logical channel ID where the resource is located, and if the information in the SI indicates that there are relatively many data packets to be sent to the base station BS in the logical channel corresponding to the highest priority logical channel identifier, that is, the UE sends out the HLID. If it means that there are relatively many data packets to do, it is necessary to relocate scheduling resources in the ring for the HLID data stream.

In the following, the method of arranging the ring scheduling resource according to the present invention will be described by dividing into a downward direction and an upward direction, for example.

The downward direction will be described with reference to the first and second embodiments.

Table 1 has deployed the "HS-DSCH MAC-d Flows Information" IE, which is a ring scheduling indication.

The "HS-DSCH MAC-d Flows Information" IE includes priority queue identifier information. The Node B receives a data stream sent by the RNC through the MAC-d stream, and stores the MAC- stored in the Node B. According to the correspondence relationship between the d stream and the priority queue, the data stream is buffered in the corresponding priority queue, and then the data stream buffered in the priority queue is extracted and transmitted to the UE. If it is a priority queue identifier included in the indication, the data stream is a data stream to which the scheduling scheduling resource is to be arranged, and the scheduling scheduling instruction (Semi) placed by the content of the last term in the "HS-DSCH MAC-d Flows Information" IE. -persistence schedule indicator information, and if the semi-persistence schedule indicator in the above embodiment is TRUE, TRUE is IE shall first means contain a ring in scheduling instructions arranged in accordance with the priority queue priority queue identifier to which the indication means is a priority queue identifier contained in the "HS-DSCH MAC-d Flows Information" IE.

After receiving the 'HS-DSCH MAC-d Flows Information' IE, the Node B determines that the ring scheduling instruction disposed in the IE is TRUE. It can be seen that the data stream is a data stream to which scheduling resources in the ring are to be arranged. Step 103 of FIG. 1 specifically includes the following contents. According to the characteristics of the data stream determined in step 102, Node B allocates the ring scheduling resource, and when the ring scheduling resource is placed, the Node B allocates the ring scheduling resource information to be allocated in the high speed shared control channel (HS-SCCH, High). Notify the UE via the speed-share control channel.

In Embodiment 2, the ring scheduling instruction of step 101 of FIG. 1 is a ring scheduling instruction arranged according to a logical channel identifier, and the indication is a radio link establishment request message, a radio link increase request, a synchronous radio link reconfiguration message, or the like.

Format. The frame head of the FP frame contains a logical channel identifier (ID) that sends the FP frame. In the following, the new information element is expressed as an SPS Logical Channel List IE, and its specific format is shown in Table 2.

[Table 2] "SPS Logical Channel List" IE

The " SPS Logical Channel List " IE includes an instruction indicating whether to arrange the ring scheduling resource for each logical channel of one UE. Herein, an indication indicating whether or not the scheduling scheduling resource is allocated to each logical channel is expressed in the form of a bit string. Since all logical channels associated with one UE have a maximum of 16, the bit string may be set to a bit string of 16 or less. The value at each bit can be set to "0" and "1", specifically "0" to indicate that no scheduling scheduling resources are placed on the corresponding logical channel and "1" to ring the corresponding logical channel. Indicates that the scheduling resource has been deployed.

After receiving the " SPS Logical Channel List " IE, the Node B can know which logical channel the data stream on which the logical stream wants to allocate in the ring by the bit string value in the IE. Step 102 of FIG. 1 specifically includes the following contents. Node B, after receiving the data stream sent by the RNC, judges according to the logical channel identifier in the data packet loaded on the data stream, and if the logical channel identifier in the data packet is declared in the indication, the ring scheduling resource must be placed. If the logical channel identifier to be used, then the data stream is the data stream to which scheduling scheduling resources are to be located. Then, Node B allocates the ring scheduling resources according to the characteristics of the data stream, and notifies the UE of the ring scheduling resource information arranged when the ring scheduling resources are arranged through the HS-SCCH.

In the downward direction, the ring scheduling instruction is also referred to as the "HS-SCCH less" instruction without the high speed shared control channel.

The ascending direction will be described with reference to the third and fourth embodiments.

The "E-DCH Logical Channel Information" IE includes a logical channel ID. As shown in Table 1, the content of the last term in the "E-DCH Logical Channel Information" IE is the semi-persistence schedule indicator information arranged, and the semi-persistence schedule indicator in the above embodiment. TRUE, TRUE indicates that the logical channel indicated by the logical channel ID included in the "E-DCH Logical Channel Information" IE is the logical channel to which the scheduling resource in the ring should be allocated.

In the case where Node B supports the enhancement characteristic of L2 (Layer2), the data packet loaded on the data stream sent by the UE to Node B is in the form of MAC-e PDU, and is a protocol data unit (MAC-e PDU, MAC). The header of the -e Protocol Data Unit includes a DDI value. The DDI value is analyzed and the analyzed value corresponds to the ID of the logical channel that sent the MAC-e PDU. In the case where Node B does not support the Layer 2 (L2) enhancement feature, the data packet loaded in the data stream sent by the UE to Node B is in the form of a protocol data unit (MAC-is PDU, MAC-is Protocol Data Unit). The header of the MAC-is PDU includes an LCH-ID value. The LCH-ID value is analyzed and the analyzed value is the ID of the logical channel that sent the MAC-e PDU.
