Description

Negotiation method, device and communication system for service quality

Technical field

The present invention relates to the field of communications technologies, and in particular, to a QoS (Quality of Service) negotiation method, apparatus, and communication system.

Background technique

In recent years, wireless communication technology has been developed at a high speed. 3GPP standardization has been developed to Rel.13. The key technologies cover the wide configuration of small cells, carrier aggregation, and 3D multiple input and multiple output (MIMO, Multiple). Multi-antenna technology of Input Multiple Output), LTE (Long Term Evolution) of unlicensed band (which can be called Licensed-Assisted-Access).

1 is a schematic diagram of an LTE wireless network showing an LTE wireless network using various technologies. The base station (eNB) is connected to the attached small cell through a loop (Backhual). There are many types of backhaul, for example, optical fiber, Asymmetric Digital Subscriber Line (ADSL), microwave, etc., and different loops have different connection quality; except for transmission media, even if there are these differences, even The same medium is used, and the amount of information exchanged between the small cell and the base station at different transmission moments is also greatly different. Therefore, the connection quality of the same loop at different times will be different. In addition, the small cell and the served user equipment (UE) use a wireless connection, and there are many kinds of wireless connections, such as LTE technology using a licensed frequency band, and LTE/WiFi technology using an unlicensed frequency band. The quality of the connection corresponding to different wireless links is also different.

As shown in FIG. 1, the base station eNB may cover the small cell 1 (the corresponding device is called SC1) and the small cell 2 (the corresponding device is called SC2), wherein, for example, the loop 1 (backhaul 1) between the eNB and the SC1 may be adopted. For optical fiber, loop 2 (backhaul 2) between eNB and SC2 can use ADSL; the connection quality of backhaul 1 and backhaul 2 is different. Both the small cell 1 and the small cell 2 can provide services for the UE, wherein the radio link between the SC1 and the UE is RL1, and the radio link between the SC2 and the UE is RL2; the connection quality of RL 1 and RL 2 is also different. .

In the existing system, if the UE wants to establish a connection with the network and wants to obtain the QoS (Qaulity of Service) level that the service wants, it needs to negotiate with the network.

2 is a schematic diagram of QoS negotiation between a UE and a network. As shown in FIG. 2, an access network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network) is connected to a service gateway (S-GW, Serving GateWay) and a packet data network gateway (P-GW, Packet Data Network GateWay). IP network. The UE performs QoS negotiation with the mobility management entity (MME, Mobile Management Entity) through the eNB, and the eNB does not directly participate in the QoS negotiation. After the MME negotiates the required QoS with the UE, the QoS parameters (for example, QoS Class Identifier (QCI) and Address Resolution Protocol (ARP) parameters are transmitted to the eNB, and the eNB performs wireless. Link connection establishment and data transmission.

It should be noted that the above description of the technical background is only for the purpose of facilitating a clear and complete description of the technical solutions of the present invention, and is convenient for understanding by those skilled in the art. The above technical solutions are not considered to be well known to those skilled in the art simply because these aspects are set forth in the background section of the present invention.

Summary of the invention

However, the inventor has found that the eNB does not obtain the loop link quality of the small cell and the quality of the radio link between the small cell and the UE in time when the eNB establishes a connection according to the QoS parameters.

According to the existing mechanism, the eNB needs to obtain the quality of the link by measuring the backhaul link of the eNB and the small cell from time to time. However, due to the very large interaction between the wireless network data transmission eNB and the small cell in the future, the backhaul link throughput will also change frequently. The untimely measurement cannot reflect the link quality change in time, so the eNB and the allocated eNB are measured based on the previous moment. The link between the small cells may not satisfy the traffic at the next moment, resulting in failure to meet the predetermined QoS. In addition, although the quality of the radio link between the small cell and the UE can be obtained by the measurement of the UE or the small cell, if it is not sent to the eNB in time, the selected small cell may not satisfy the set QoS.

The foregoing and other features of the present invention will be apparent from the The specific embodiments of the present invention are disclosed in the specification and the drawings, which are illustrated in the embodiment of the invention The invention includes all modifications, variations and equivalents falling within the scope of the appended claims.

Example 1

An embodiment of the present invention provides a method for negotiating a service quality, and an embodiment of the present invention is described from a base station side. FIG. 3 is a schematic diagram of a method for negotiating service quality according to an embodiment of the present invention. As shown in FIG. 3, the negotiation method includes:

Step 301: The first base station receives a service request sent by the user equipment.

Step 302: Based on radio link information of a radio link between the user equipment and one or more second base stations capable of providing services for the user equipment, and the one or more second base stations and the The loop link information of the loop between the base stations, the first base station and the core network perform service quality negotiation for the service request;

Step 303: The first base station performs connection configuration of the service request according to the result of the service quality negotiation.

In this embodiment, the first base station may be a macro base station (eNB); the second base station is a small cell base station (also referred to as a transmission point) within the coverage of the macro base station, and may be a micro base station (for example, a Pico base station). It can also be a remote radio head (RRH) or a femto base station (such as a Femto base station). However, the present invention is not limited thereto, and for example, the first base station may also be a micro base station. Hereinafter, only the first base station is a macro base station (eNB), and the second base station is a micro base station (Pico base station) as an example.

In this embodiment, there may be multiple second base stations in the coverage of the first base station, and a backhaul is provided between the first base station and each second base station; each second base station may actively or passively feed back Loop link information for the loop between the first base stations. Thereby, the first base station can obtain loop link information of a loop with each of the second base stations.

In addition, the second base station provides a service for the user equipment, and the second base station and the user equipment have a wireless link; each second base station can feed back the resource occupation information of the wireless link to the first base station, and the user equipment can also directly Or indirectly feeding back quality information of the wireless link to the first base station. Thus, the first base station can obtain wireless link information of the wireless link between the user equipment and the second base station capable of providing service to the user equipment.

It is worth noting that the second base station and the user equipment reporting loop link information and radio link information are not required. For example, the first base station may further preset a number of empirical values of the loop link information and the radio link information, and perform QoS negotiation with the core network according to the experience value. The second base station and the user equipment report the loop link information and the radio link information, so that the first base station can better know the link situation and flexibly configure the connection of the service required by the user equipment.

In this embodiment, the first base station performs a target with the core network based on the wireless link information and the loop link information. The service quality negotiation of the service request, and the connection configuration of the service request is performed according to the result of the service quality negotiation. Therefore, the eNB does not participate in the QoS negotiation in the existing mechanism. In the embodiment of the present invention, the QoS negotiation capability between the user equipment and the network can be effectively improved by the base station participating in and assisting the QoS negotiation.

In this embodiment, the connection configuration of the service request according to the result of the service quality negotiation in step 302 may include: if the service quality provided by the access network within the range of the base station can satisfy the service request, Determining, by the first base station, a second base station serving as the user equipment from one or more second base stations capable of providing services for the user equipment according to the wireless link information and the loop link information; The first base station rejects the service request if the quality of service provided by the access network in the range of the base station cannot satisfy the service request.

For example, after the eNB obtains the quality information of the backhual and the radio link, the eNB may reject the service request if it can find that the QoS that can be provided cannot satisfy the service requirement when performing QoS negotiation with the core network (for example, including the MME and the PGW); If it is found that there is a suitable small cell under the eNB and the wireless connection can support the QoS, the service request is agreed, and a suitable backhaul and a wireless link can be selected.

4 is a schematic diagram of a wireless network for performing QoS negotiation according to an embodiment of the present invention, showing a case where a second base station and a user equipment report loop link information and wireless link information. As shown in FIG. 4, the wireless network may include an eNB and two transmission points SC-A and SC-B, and both SC-A and SC-B may provide services for the UE.

Before the UE attempts to initiate a new service, the SC-A can feed back the loop link information of the loop between the SC-A and the eNB (loop 1), and the SC-B can feed back the loop between the SC-B and the eNB (loop 2). Link information. Moreover, the SC-A can also feed back the radio link resource occupation information of the SC-A, and the SC-B can also feed back the radio link resource occupation information of the SC-B. In addition, the UE may directly or indirectly feed back to the eNB the radio link quality information of the radio link (RL1) with the SC-A and the radio link quality information of the radio link (RL2) with the SC-B. .

When the UE attempts to initiate a new service, the eNB may perform QoS negotiation with the core network according to the request of the new service and the foregoing loop link information and the wireless link information; for example, the QoS level required by the service and the QoS that the access network can reach. Negotiate whether the levels are consistent.

FIG. 5 is another schematic diagram of a wireless network for performing QoS negotiation according to an embodiment of the present invention, showing a case where a connection configuration of a service request is performed according to a result of QoS negotiation.

For example, after negotiation, it is found that both SC-A and SC-B can achieve the required QoS level, and the eNB can select the UE based on the principle of the lowest resource occupancy rate or the principle of the lowest power consumption. The second base station. As shown in FIG. 5, for example, SC-A is selected to provide services for the UE, that is, select a suitable loop (loop 1) and a radio link (RL1).

Therefore, based on the loop link information and the radio link information, the base station can select an appropriate backhual link and a radio link when establishing a service connection with the core network side, so that the QoS requirements and the effective utilization of resources are simultaneously satisfied.

The above describes the case where the base station participates in QoS negotiation. The following is a further description of how to feedback loop link information and wireless link information.

The indication may be performed by signaling, and each small cell is required to feed back backulul information; after receiving the signaling, each small cell feeds back information about the backhaul link with the eNB.

Alternatively, the loop link information may also be fed back periodically; for example, each small cell may measure itself and feed back by cycle. In addition, the loop link information can also be fed back when the preset conditions are met, such as feedback by event; for example, feedback when the backhaul throughput is below a certain threshold, or feedback when the backhaul delay exceeds a certain threshold ,and many more. The present invention is not limited to this, and a specific feedback manner can be determined according to actual conditions.

However, the present invention is not limited thereto, and may include other wireless chains, for example. Road information.

In this embodiment, the eNB may request each small cell to feed back its radio link resource occupation information, and the small cell may also actively feed back the radio link resource occupation information. The eNB may request the UE it serves to feed back the radio link quality information of each small cell that can provide services for the UE, and the UE may also actively feed back the radio link quality information. In addition, the radio link quality information may be directly fed back to the eNB by the UE, or may be indirectly fed back to the eNB by the UE through the small cell.

Step 603: The first base station receives a service request sent by the user equipment.

In this embodiment, when the UE attempts to initiate a new service, the UE may directly send a service request to the first base station; or indirectly send a service request to the first base station through the serving cell.

Step 604: Based on the radio link information and the loop link information, the first base station and the core network perform service quality negotiation for the service request. For details on QoS negotiation, refer to related technologies.

Step 605: The first base station performs connection configuration of the service request according to the result of the service quality negotiation.

It should be noted that the order of the above various steps is not limited thereto; for example, step 602 may be completed before step 601, or step 601 and step 602 may be performed in parallel. In addition, the feedback of the radio link resource occupation information and the radio link quality information in step 602 may be in no particular order.

In this embodiment, the quality information of the backhaul link of the small cell and the eNB is fed back by the small cell, and the quality information of the radio link of the small cell that the UE can provide the service to the UE is fed back by the UE, and the base station can flexibly configure and match. The connection required by the UE for QoS, including the backhual link and the wireless link. Therefore, the eNB can efficiently improve the QoS negotiation capability of the UE and the network, and improve the quality of each link between the UE and the eNB, including the radio link of the UE and the small cell, and the backhual link between the small cell and the eNB.
