Description

Resource allocation method, base station, resource request method and user equipment

The present invention relates to a resource allocation method, a base station, a resource request method, and a user equipment, and particularly relates to a resource allocation method and a base station capable of achieving traffic offloading in heterogeneous networks (HetNet). Resource request method and user equipment.

With the development of technology and the progress of the times, a variety of mobile communication devices have become an indispensable part of people's lives. However, when too many mobile communication devices are attached to a limited number of enhanced Node Bs (eNodeBs, eNBs), an overload situation may occur on the cellular network. At this point, users of mobile communication devices may experience discontinuous or lower communication service quality, resulting in a poor user experience. Therefore, network operators need to solve these problems.

In order to solve the problem of network overload, the Third Generation Partnership Project (3GPP) proposed small cells. the concept of. Small cells can be used to extend the coverage of macro cells and increase the signal intensity at the cell edge, thereby increasing the data rate of mobile communication devices. However, small cells still suffer from problems such as insufficient bandwidth and interference. For example, small cells generally use the same frequency as giant cells without increasing the channel bandwidth, thus creating a situation of interference with giant cells. In order to avoid this problem, small cells need to perform interference avoidance and elimination operations. On the other hand, since small cells have not been widely deployed in recent years, if the network operator wants to solve the above problems, the cost of its construction will be quite high.

In recent years, wireless local area networks (WLANs) have been widely deployed in many places, especially in buildings. The RAN2 organization in 3GPP, which is responsible for the radio layers 2 and 3, begins to discuss the interworking between WLAN and 3GPP access networks, namely HetNet. The main advantage of HetNet is that each radio access technology (NAT) uses a different frequency, thus achieving a higher capacity gain. In terms of deployment, network operators can use giant cells to achieve large coverage while achieving high capacity with HetNet.

Although HetNet can solve the current problems of network operators, there are still many difficulties to be solved in its implementation. First, the notification mechanism between HetNet will be the first difficulty. In particular, since different RATs use different co-adapters to communicate with devices in their networks, a notification mechanism that can integrate and coordinate these RATs is needed. Second, the second difficulty lies in the need to meet the service requirements of mobile communication devices. In a homogeneous network, mobile communication devices may experience poor channel quality, thus May need to be handoff. However, using different RATs may suffer from different wireless communication conditions and violate quality of service (QoS). In order to avoid a poor user experience and efficient use of network resources, it is important to allocate resources based on service characteristics to mobile communication devices in different RATs.

In addition, the third difficulty is to determine the target network. An overly trivial decision-making algorithm can not only lead to low-network users, but also lead to network bottlenecks. On the other hand, the global decision-making algorithm in HetNet will be quite complicated due to the need to consider the channel situation, the network situation and the situation of the mobile communication device. For example, most mobile communication devices today support dual-mode communication modes for WLAN and cellular networks. Users need to decide which network to use. In this case, different users may choose the same target network, which may cause the network to be overloaded.

Many studies on HetNet decision algorithms have been proposed today. However, few studies have focused on making decisions while considering multiple mobile communications devices and network information. If a decision algorithm only considers the information of a single mobile communication device, such as location information, received signal strength (RSS), and signal to noise ration (SNR), the network may be overloaded. The situation makes this decision algorithm unable to guarantee the smooth operation of mobile communication devices.

On the other hand, if a decision-making algorithm only considers network information, such as network load, network characteristics, and cost, it cannot improve the channel without considering the channel quality between the channel mobile communication device and the network. Usage rate and service The experience makes this decision algorithm unable to produce comprehensive decision results. In addition, even if a decision-making algorithm combines information from a single mobile communication device with network information, its decision may not achieve a low service blocking rate. For example, when a mobile communication device has multiple candidate networks, the decision cannot increase the usage of multiple networks without considering the candidate network of the mobile communication device. Therefore, network operators need to comprehensively consider the information of multiple mobile communication devices and network information to achieve the required QoS and increase network usage.

In view of this, the embodiments of the present invention provide a resource allocation method, a base station, a resource request method, and a user equipment. The resource request method can effectively provide information of the user equipment to the base station reference.

The A/D converter or D/A converter is configured to convert the analog signal format to a digital signal format during uplink (ie, UE to base station 110) signal processing, while the downlink (ie, base station 110 to UE) signals Processing period The converted digital signal format is an analog signal format.

The UEs 120_1~120_N may individually include a transceiver module, a communication protocol module, and a memory (not shown). Taking the UE 120_1 as an example, it may include a transceiver module 122 and a communication protocol module 124. Both the transceiver module 122 and the memory can be connected to the communication protocol module 124. The transceiver module 122 can be configured to transmit and receive signals from other devices within its coverage. The transceiver module 122 can perform analog digital signal conversion, digital analog signal conversion, modulation, demodulation, signal amplification, low-pass filtering, and band pass filtering ( Bandpass filtering). For example, the transceiver is configured to provide information of the received signal to the protocol module, to tune the data received from the protocol module to a modulated signal, and to transmit the modulated signal to other devices.

The protocol module 114 of the base station 110 and the protocol module (e.g., the protocol module 124) of the UEs 120_1~120_N may be configured to receive a request message and process the commands in the message. (or perform the appropriate action based on the parameters in the message). The protocol module can include a processor and an embedded software or firmware. The embedded software or firmware program may include a code of a Communication Protocol Stack. Additionally, the memory can be configured to temporarily store various parameters or other materials. The UEs 120_1~120_N may further include other components (eg, antenna modules) for implementing the above functions of the transceiver, the protocol module, and the memory. According to the wireless network implementation scheme of the base station 110, such as CDMA, WCDMA, GSM, UMTS, 3G, 4G, WiMAX, LTE, etc., and other components may also be included in the UEs 120_1~120_N and the base station 110.

In this embodiment, the UE 120_1~120_N individual communication protocol modules can integrate the channel quality between the UE and the one or more base stations into a target list, and attach the target list to a specific signal (for example, The measurement report defined in LTE is sent to a base station for reference by the base station as a communication resource allocation.

Taking the UE 120_1 as an example, if the transceiver module 122 can measure the channel quality with a plurality of specific base stations (including the base station 110), the protocol module 124 can generate a target list according to the quality of the channels. . It should be understood that the plurality of specific base stations are not limited to base stations operating in the same communication standard, but may be base stations operating separately for different communication standards such as WLAN and LTE. In other words, the plurality of specific base stations can form a HetNet.

In this target list, the communication protocol module 124 of the UE 120_1 can arrange each specific base station and corresponding channel quality in descending order. That is, in the target list generated by the UE 120_1, the specific base station ranked first is the base station having the best channel quality for the UE 120_1, and the specific base station ranked second is the UE 120_1. A base station with sub-optimal channel quality. The channel quality relationship between the other specific base stations in the target list of the UE 120_1 and the UE 120_1 should be derived according to the teachings herein, and details are not described herein.

After the protocol module 124 generates its target list, the protocol module 124 can control the transceiver module 122 to send the target list to the specific base station. one of them. In one embodiment, the protocol module 124 can control the transceiver module 122 to only send its target list to a particular base station that has the best channel quality for the UE 120_1, but not to other specific base stations. For example, assuming that the channel quality between the UE 120_1 and the base station 110 is optimal for the UE 120_1, the protocol module 124 can control the transceiver module 122 to send its target list to the base station 110.

Based on the foregoing teachings, the UEs 120_2~120_N may also perform operations similar to the UE 120_1 to send their individual target lists to the corresponding specific base stations, and details are not described herein again.

2 is a flow chart of a resource allocation method according to an embodiment of the invention. The method proposed in this embodiment can be performed by the base station 110 in FIG. 1, and the detailed steps of the method will be described below with the respective components of FIG.

In step S210, the transceiver module 112 can receive at least one target list corresponding to the at least one UE. For convenience of explanation, it is assumed that the at least one target list received by the transceiver module 112 corresponds to the UEs 120_1~120_N, but the embodiments of the present invention are not limited thereto. It should be noted that the at least one target list received by the transceiver module 112 is not necessarily sent by the UEs 120_1~120_N, but may also be forwarded by other specific base stations, and the details will be later. Explain in the space.

Next, in step S220, the communication protocol module 114 can find the UE with the lowest channel resource requirement from the UEs 120_1~120_N. The channel resource requirement is, for example, a bandwidth required by the UE when transmitting data, but is not limited thereto.

Thereafter, in step S230, the communication protocol module 114 can determine whether the load status of the base station 110 is 2 or not to serve the UE. If yes, the protocol module 114 can continue to step S240; if not, the protocol module 114 can continue to step S250.

In an embodiment, the load status of the base station 110 can be characterized as the remaining bandwidth that the base station 110 can allocate. In this case, when the bandwidth required by the UE with the lowest channel resource requirement does not exceed the remaining bandwidth, the protocol module 114 determines that the load status of the base station 110 is sufficient to serve the UE, and thus the steps can be continued. S240. On the other hand, when the bandwidth required by the UE with the lowest channel resource requirement exceeds the remaining bandwidth, the protocol module 114 determines that the load status of the base station 110 is insufficient to serve the UE, and thus may proceed to step S250. .

In step S240, the communication protocol module 112 can allocate communication resources to the UE according to the minimum channel resource requirement. Specifically, the protocol module 112 can allocate the bandwidth required by the UE to the UE from the remaining bandwidth that has not been allocated.

From another point of view, the UEs 120_1~120_N are not connected to the base station 110 according to the channel quality between the base station 110, but the base station 110 determines whether it is sufficient to serve the UEs 120_1~120_N according to the load status thereof. UE with the lowest channel resource requirements. In this way, the present invention proposes a method to avoid an overload situation caused by a large number of UEs simultaneously connected to the base station 110.

In step S250, the communication protocol module 112 may not allocate communication resources to the UE, and forward the target list corresponding to the UE in the target list. From another point of view, when the base station 110 is connected to the UE with the lowest channel resource requirement, it cannot serve At this time, this means that the network usage of the base station 110 has been fully utilized. In this case, base station 110 may forward the target list of UEs with the lowest channel resource requirements to one of the plurality of particular base stations.

In an embodiment, assuming that the plurality of specific base stations and their channel qualities are arranged in descending order of the target list of the UEs having the lowest channel resource requirements, the base station 110 may forward the target list to the The specific base station in the target list that is next to the base station 110, that is, the channel quality with the UE is second only to the specific base station of the base station 110.

In other embodiments, after step S250, base station 110 may inform other specific base stations that they have completed resource allocation while forwarding the target list.

In short, the base station 110 proposed by the present invention can comprehensively consider the information of multiple UEs and the network information of the base station 110, thereby effectively avoiding the overload of the base station 110 and improving its network usage. On the other hand, when the base station 110 determines that its load status is insufficient to serve the UE having the lowest channel resource requirement for the base station 110, the base station 110 can hand the UE to another specific base station for service. In other words, the UE is less blocked from being inadvertently connected to a certain base station in a high load state, but can be served by a base station having a service capability (for example, a low load state). As a result, the overall network service blocking rate can be effectively reduced, thereby improving the user's service experience.

In other embodiments, the base station 110 can determine the order in which the communication resources are allocated by each specific base station by exchanging load status with other specific base stations. Taking the base station 110 as an example, before the step S220 of FIG. 2, the transceiver module Group 112 can obtain the current load status corresponding to other specific base stations. Moreover, the communication protocol module 114 can determine whether the load status of the base station 110 is higher than each current load status corresponding to another specific base station.

If the load status of the base station 110 is higher than the respective current load status corresponding to other specific base stations, this means that the base station 110 is the closest one of the plurality of specific base stations, and thus can execute Figure 2 before other specific base stations. The method is to allocate the communication resources of the base station 110. In this case, since the base station 110 will preferentially allocate the remaining communication resources to the UE having the lowest communication resource requirement, it is possible to effectively avoid the situation in which the base station 110 is overloaded.

If the load status of the base station 110 is not higher than the respective current load status corresponding to the other specific base stations, the base station 110 may allocate the communication resources of the base station 110 to the other specific base stations. In other words, the base station 110 will allow other heavily loaded specific base stations to preferentially perform the method of FIG. 2 to allocate corresponding communication resources, thereby avoiding an overload situation on these particular base stations.

In other embodiments, since the load status of the base station 110 may be sufficient to serve one or more UEs, the appropriate UE may be selected from the considered UEs to allocate communication resources through the mechanism shown in FIG. Moreover, when the channel quality between the base station 110 and a certain UE is too poor, even if the load status of the base station 110 is sufficient to serve the UE, the base station 110 may not allocate communication resources to the UE.

Please refer to FIG. 3. FIG. 3 is a flowchart of a resource allocation method according to the embodiment of FIG. 2. The method proposed in this embodiment can be performed by the base station 110 in FIG. 1, and the detailed steps of the method will be described below with the respective components of FIG.

In step S310, the transceiver module 112 can receive at least one target list corresponding to the at least one UE. In step S320, the communication protocol module 114 can find the UE with the lowest channel resource requirement from the UEs 120_1~120_N. In step S330, the communication protocol module 114 can determine whether the load status of the base station 110 is sufficient to serve the UE. If yes, the protocol module 114 can continue to step S340; if not, the protocol module 114 can continue to step S380. For details of the steps S310 to S330, refer to the description of steps S210 to S230 in FIG. 2, and details are not described herein again.

In step S340, the communication protocol module 114 can determine whether the specific channel quality between the base station 110 and the UE is lower than the channel quality threshold. If yes, the protocol module 114 can continue to step S380; if not, the protocol module 114 can continue to perform steps S350-S370 and return to step S320. The channel quality threshold is, for example, an ideal channel quality (ICQ) of the UE, which can be set by the designer to any index value according to requirements, for example, an SNR of 10, etc., but the present invention The embodiments are not limited thereto.

In step S380, the communication protocol module 112 may not allocate communication resources to the UE, and forward the target list corresponding to the UE in the target list. For details of step S380, refer to the description of step S250 in FIG. 2, and details are not described herein again.

In other words, when the quality of the channel between the UE having the lowest channel resource requirement and the base station 110 is too poor, in order to prevent the UE from experiencing a poor experience such as an unclear signal and a discontinuous call process when using the service, The base station 110 can hand this UE to other specific base stations for resource allocation.

In step S350, the protocol module 112 can be based on the lowest channel resource. It is required to allocate communication resources to this UE. For details of step S350, refer to the description of step S240 in FIG. 2, and details are not described herein again.

At this time, since the base station 110 has allocated communication resources to the UE having the lowest channel resource requirement, the communication protocol module 114 may update the load status of the base station 110 according to the communication resource in step S360. Next, in step S370, the communication protocol module 114 may exclude the UE from the at least one UE, and return to step S320. That is, the base station 110 may find the UE with the lowest channel resource requirement from other UEs that have not been allocated communication resources, and perform steps S330-380 according to the details, and details thereof are not described herein again.

As taught in the previous embodiment, the base station 110 and other specific base stations may mutually exchange load states with each other before allocating communication resources to the respective UEs, so as to determine the allocation of communication resources according to the load status of each specific base station. The order (for example, a specific base station that is heavily overloaded allocates communication resources first).

Therefore, in an embodiment, even after the base station 110 has completed its own communication resource allocation operation, the base station 110 does not immediately establish a connection with the UE it serves according to its communication resource allocation operation, but will wait for each specific base station. After the communication resource allocation operation for the UE is completed, the connection with the UE served by the base station 110 is established.

In summary, the resource request method and the UE proposed by the embodiment of the present invention can integrate the channel quality between the UE and the multiple base stations into a target list, and send the target list to the multiple of the platforms. One, in turn, allows the base station receiving the target list to make the best distribution of communication resources. The capital proposed by the embodiment of the invention The source allocation method and its base station may, after receiving the target list corresponding to the UE, determine whether to serve the UE with the lowest channel resource requirement among the considered UEs according to the load status thereof. When the base station determines that its load status is sufficient to serve the UE, the base station will allocate communication resources to the UE. In other words, each UE does not determine the base station to be connected according to the channel quality between it and each base station. In this case, the base station can allocate the remaining communication resources as much as possible, thereby achieving the effect of high network usage. Moreover, since the base station does not serve the UE whose load state cannot be loaded, it is possible to avoid an overload situation at the same time.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and any one of ordinary skill in the art can make some changes and refinements without departing from the spirit and scope of the present invention. The scope of the invention is defined by the scope of the appended claims.
