detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

Before describing the embodiment of the present invention, first understand the relevant information of the traditional cellular network and the 5G network.

The design of traditional cellular networks is centered on the cell, that is to say, user access/establishment/removal, network coverage, resource scheduling, mobility management, signaling control, planning/optimization, etc. are all carried out with independent cells of.

The 5G network, with high real-time synchronous collaboration requirements as the norm, is oriented to big data business scenarios and dense node deployment scenarios. From the capability indicators of the 5G network, it can be seen that the traditional network architecture can no longer meet the needs of the 5G era. If the traditional network architecture is still used to achieve the capability index of the 5G network, the relationship between users in the cell and between cells will become more and more complicated. At the same time, the resource occupation method of the public channel of the traditional cellular network has become a serious burden on the network in the 5G high-density scenario; and the signaling control process under the traditional cellular network can no longer meet the fast and flexible air interface requirements of 5G. As a result, when traditional cellular networks face 5G scenarios, there are problems such as high signaling overhead and prolonged signaling processing time in resource allocation, which makes it impossible to meet the higher service needs of users.

Therefore, in view of the diverse scenarios in the 5G network that require diverse network technology requirements, the design of the 5G wireless network should rethink the design principle of the center of the cell.

Based on this, in various embodiments of the present invention: the decellularization unit of the base station uses the cell resources obtained by the base station itself to allocate corresponding cell resources for the UE; the first Cell_MAC unit of the base station allocates the corresponding cell resources for the UE based on the Cell resources, on the cell resources allocated for the UE, allocate radio resources corresponding to the service for the UE; the base station includes more than one Cell_MAC unit; the first Cell_MAC unit is the cell resource allocated for the UE The corresponding Cell_MAC unit.

It should be noted that the first, second, ... used herein only represent different Cell_MAC units, and do not limit the functions of the Cell_MAC units.

Embodiment one

The base station provided in this embodiment, as shown in FIG. 1, the base station includes: a No More Cell (No More Cell) unit 11 and a first Cell_MAC unit 12; wherein,

The de-celling unit 11 is configured to allocate corresponding cell resources to the UE by using the cell resources obtained by the base station itself;

The first Cell_MAC unit 12 is configured to allocate radio resources corresponding to services for the UE on the cell resources allocated for the UE based on the transmission characteristics of the UE; the base station includes more than one Cell_MAC unit; the second A Cell_MAC11 unit is a Cell_MAC unit corresponding to the cell resources allocated for the UE.

Wherein, in actual application, the base station may obtain the resource of each cell through reporting by the UE or interacting with other base stations.

Here, in actual application, for the application scenario of 5G network, the solution of this embodiment can be applied to the application scenario of macro base station + micro base station. Correspondingly, at this time, the resources of each cell obtained by the base station are micro Each cell resource corresponding to the base station.

The decellularization unit 11 is specifically configured to: use the obtained cell resources to allocate corresponding cell resources to the UE based on a global or local optimal convergence algorithm.

In an embodiment, the decellularization unit 11 may include: a control plane signaling processing module, configured to use the obtained cell resources to allocate corresponding cell cluster resources to the UE based on a global or local optimal convergence algorithm ; and based on the global or local optimal convergence algorithm, and in combination with the allocated cell cluster resources, allocate corresponding cell resources for the UE.

More specifically, in an embodiment, as shown in FIG. 2 , the decellularization unit 11 may include: a control plane signaling processing submodule 111 and a centralized scheduling submodule 112; wherein,

The control plane signaling processing submodule 111 is configured to allocate corresponding cell cluster resources to the UE based on the global or local optimal convergence algorithm by using the obtained cell resources;

The centralized scheduling submodule 112 is configured to allocate corresponding cell resources to the UE based on a global or local optimal convergence algorithm and in combination with allocated cell cluster resources.

That is to say, in actual application, the control plane signaling processing submodule 111 and the centralized scheduling submodule 112 may be set together to form the control plane signaling processing module.

When the UE needs to perform services, the decellularization unit 11 uses the cell resources obtained by the base station itself to allocate corresponding cell resources for the UE; correspondingly, the first Cell_MAC unit 12 based on the transmission characteristics of the UE, On the cell resources allocated to the UE, allocate radio resources corresponding to services to the UE, so that the allocated radio resources can be used to transmit service data subsequently.

Wherein, since the function of the decellularization unit 11 is to be realized, the decellularization unit 11 is required to have the ability of cloud computing based on big data.

The allocated cell resources include the power, identity, channel, etc. of the cell.

Since the control plane signaling processing sub-module 111 uses the obtained cell resources to allocate corresponding cell cluster resources to the UE based on a global or local optimal convergence algorithm, all cell resources must be used to allocate corresponding cell cluster resources. The amount is massive, so the processing speed of this process is relatively slow (such as a radio resource control (RRC, Radio Resource Control) process), and the centralized scheduling submodule 112 allocates a corresponding resource for the UE in combination with the allocated cell cluster resources The amount of data in the cell resources is relatively small, so the processing speed of this process is relatively fast.

In one embodiment, during the business process, the decellularization unit 11 is also used to transmit and process business data from the core network;

The first Cell_MAC unit 12 is further configured to use the radio resource allocated for the UE to send the service data after transmission processing to the UE through an air interface.

In addition, in the process of performing the service, it is also necessary to transmit other user plane data except the service data. At this time, the first Cell_MAC unit 12 is also used to transmit other user plane data except the service data The data is processed for transmission, and other user plane data after transmission processing is sent to the UE through the air interface by using the radio resources allocated for the UE.

Here, the transmission processing refers to various processing required for sending the user plane data delivered by the core network to the UE, such as compression, encryption and so on.

The service data may be user plane data processed based on Packet Data Convergence Protocol (PDCP, Packet Data Convergence Protocol)/Radio Link Control (RLC, Radio Link Control) protocol, etc.; the other user plane data may be based on Transmission Control Protocol (TCP, Transmission Control Protocol)/Internet Internet Protocol (IP, Internet Protocol) processed high-level user plane data, etc.

As shown in FIG. 3 , the decellularization unit 11 may further include: a user plane data packet processing module 113, configured to process service data from the core network based on the resource allocation result of the control plane signaling processing submodule 111 transmission processing;

Correspondingly, the centralized scheduling submodule 112 is configured to allocate a corresponding cell cluster resource for the UE based on a global or local optimal convergence algorithm, combined with the processing result of the user plane data packet processing module 113 and the allocated cell cluster resources. Cell resources, and send the service data after transmission processing to the first Cell_MAC unit;

The first Cell_MAC unit 12 is configured to send the service data after transmission processing to the UE through the air interface after receiving the service data sent by the centralized scheduling sub-module.

In an embodiment, during service use, the location of the UE may move, thereby triggering cell handover. In this case, when the UE undergoes cell handover due to location movement, the control The signaling processing sub-module 111 is further configured to re-allocate corresponding cell cluster resources to the UE based on the global or local optimal convergence algorithm by using the obtained cell resources;

Correspondingly, as shown in FIG. 4 , the centralized scheduling submodule 112 is configured to reallocate corresponding cell resources for the UE based on a global or local optimal convergence algorithm and in combination with reallocated cell cluster resources;

The second Cell_MAC unit 13 is configured to allocate radio resources corresponding to services for the UE on the cell resources re-allocated for the UE based on the transmission characteristics of the UE; and use the allocated radio resources for the UE The wireless resource is used to send the service data after the transmission process to the UE through the air interface; the second Cell_MAC unit 13 is a Cell_MAC unit corresponding to the cell resource re-allocated for the UE.

It should be noted that: in the above embodiment, when the control plane signaling processing submodule 111 and the centralized scheduling submodule 112 are combined to form the control plane signaling processing module, the control plane signaling The processing module executes the functions of the control plane signaling processing submodule 111 and the centralized scheduling submodule 112.

It can be seen from the above description that the solution of the embodiment of the present invention is a design idea of removing cells (No More Cell) for the base station, and adopts hierarchical centralized wireless access control to realize fast/ Slow resource scheduling, coordination and switching.

Specifically, the resource control and coordination functions of the entire network (such as all micro base stations controlled by the base station itself) are centralized in units of radio resource management units (cells) necessary on the network side. This resource control and coordination function mainly includes radio resource management. (RRM, Radio Resource Management) and media access control (MAC, Media Access Control) control and coordination function, this control and coordination function is especially suitable for slow control across cells (such as RRC process, etc.), such as System information distribution, identity distribution, mobility handover between large areas, etc., so as to realize real-time collaboration of real-time synchronization of air interfaces across cells.

Based on the description of the functions of each unit in the base station above, a schematic diagram of the network architecture shown in FIG. 5 can be obtained. As shown in Figure 5, the base station adopts the basic idea of decellularization, and centralizes the control and coordination of the cell resources of the entire network (such as all micro base stations controlled by the base station itself) through the decellularization unit, and delegates the function of fast air interface control to the The Cell_MAC unit of the base station shown in Figure 5, that is to say, each Cell_MAC unit mainly implements two functions: for the lower part (UE), it provides high real-time control for the flexible air interface; The control plane of the network provides corresponding services, so that the decellularization unit realizes its own functions.

In other words, the base station implements centralized control and coordination of radio resources by removing cellular units, and this centralized control and coordination can be referred to as centralization of the control plane.

At the same time, the user plane data packet processing module of the cellular unit centralizes the data processing function of the entire network (such as all the micro base stations controlled by the base station itself), transmits and processes business data in a centralized manner, and increases the fine processing of business data, that is, realizes Big data calculation of business data to reduce data movement, such as centralized transmission and processing of business data based on PDCP/RLC protocol, so as to realize rapid transmission of business data. However, the processing function of user plane data other than service data, such as high-level user plane data processed based on TCP/IP, is moved down to the corresponding Cell_MAC unit, and the Cell_MAC unit processes other user plane data except the service data. Perform transmission processing to provide users with richer data services.

The decellularization unit allocates corresponding cell resources to the UE based on the obtained cell resources and based on a global or local optimal convergence algorithm. In other words, the decellularization unit concentrates the computing functions of a large number of cells, quickly calculates the global or local optimal convergence results, and provides users with the most suitable wireless resources (including: Physical Resource Block (PRB, Physical Resource Bulk), Power, etc.) services; and after obtaining the global or local (Cell level) optimal convergence results, it is distributed to the Cell_MAC unit, and the corresponding Cell_MAC unit then allocates the corresponding air interface resources for the UE, so as to realize the rapid allocation of air interface resources . Therefore, the computing power of decellularized cells can be considered as a kind of centralized computing power.

In addition, from the perspective of links, as shown in Figure 5, user links are divided into centralized user links (links shown by "←→" in Figure 5) and decentralized user links (links shown in Figure 5 middle link shown); specifically, the user link from the Cell_MAC unit to the core network (CN) unit modules is a centralized user link, while the Cell_MAC unit to the air interface adopts a decentralized user link road. in,

The centralized user link uses the traditional radio bearer to transfer services, which can be regarded as a semi-static link, which is only responsible for carrying specific services. In other words, when the service changes, the centralized user link will change, and when the service does not change, the centralized user link will not change, so the user link can be called a semi-static link.

Distributed user links, according to the user's channel status on the air interface and the needs of the entire network, dynamically select the appropriate physical (PHY) channel to send data to the air interface in real time. In other words, the decentralized user link is a dynamic link .

Centralized and decentralized user links are based on the control, data, and computing structures provided by the centralized control plane, centralized user plane, and centralized computing capabilities to achieve real-time collaboration with the real-time synchronization of the air interface. The advanced air interface transmission technology breaks through the flat control method of the traditional network architecture and realizes the "No More Cell" function of the network.

Here, it should be noted that: as shown in Figure 5, in actual application, there are corresponding signaling between each Cell_MAC unit and the control plane signaling processing submodule, the centralized scheduling submodule, and between the modules of the decellularization unit. Command interaction to realize resource allocation and data transmission, as shown in the thick solid line in Figure 5 shown.

In actual application, the decellularization unit 11, the first Cell_MAC unit 12, the control plane signaling processing module, the control plane signaling processing submodule 111, the centralized scheduling submodule 112, and the user plane data packet processing module 113, the second The Cell_MAC unit 13 can be composed of a central processing unit (CPU, Central Processing Unit), a microprocessor (MCU, Micro Control Unit), a digital signal processor (DSP, Digital Signal Processor) or a programmable logic array (FPGA, Field-Programmable GateArray) implementation.

In the base station provided by the embodiment of the present invention, the decellularization unit 11 allocates corresponding cell resources for the UE by using the cell resources obtained by the base station itself; the first Cell_MAC unit 12 allocates the cell resources based on the UE, On the cell resources allocated for the UE, allocate radio resources corresponding to the service for the UE; the base station includes more than one Cell_MAC unit; the first Cell_MAC unit 12 is a cell resource corresponding to the UE allocated In this way, the Cell_MAC unit adopts centralized resource control and coordinated processing methods, which can effectively reduce signaling overhead and signaling processing delay, thereby effectively meeting the real-time collaboration requirements of high real-time synchronization and improving user experience.

In addition, during the service process, the decellularization unit 11 transmits and processes the service data from the core network; the first Cell_MAC unit 12 uses the wireless resources allocated for the UE to transmit the service data after transmission and processing through the air interface Sending to the UE, in this way, the data processing speed can be effectively improved, and the user experience can be further improved.

When the UE undergoes cell handover due to location movement, the control plane signaling processing submodule 111 uses the obtained cell resources to re-allocate the corresponding cell cluster for the UE based on a global or local optimal convergence algorithm resources; the centralized scheduling submodule 112 re-allocates corresponding cell resources for the UE based on a global or local optimal convergence algorithm combined with the reallocated cell cluster resources; the second Cell_MAC unit 13 utilizes According to the transmission characteristics of the UE, on the cell resources re-allocated for the UE, allocate radio resources corresponding to the service for the UE; and use the radio resources allocated for the UE to send the service data after transmission to the UE through the air interface The UE; the second Cell_MAC unit 13 is the Cell_MAC unit corresponding to the cell resources re-allocated for the UE, so that the signaling overhead and signaling processing delay can be further effectively reduced, and the air interface can be further effectively implemented. Real-time collaboration for real-time synchronization.

In addition, since the base station in the embodiment of the present invention only needs to be modified in software, it has good scalability and can quickly support a large number of users. Moreover, it has good compatibility, and can be well compatible with 3G, 4G and other networks.

Embodiment two

Based on the base station of the embodiment of the present invention, this embodiment provides a resource allocation method, as shown in FIG. 6, the method includes the following steps:

Step 601: the decellularization unit of the base station uses the cell resources obtained by the base station itself to allocate corresponding cell resources for the UE;

Specifically, the decellularization unit allocates corresponding cell resources to the UE based on a global or local optimal convergence algorithm by using the obtained cell resources.

More specifically, the control plane signaling processing submodule of the decellularization unit allocates corresponding cell cluster resources to the UE based on the obtained cell resources based on a global or local optimal convergence algorithm;

The centralized scheduling submodule of the decellularization unit allocates corresponding cell resources for the UE based on a global or local optimal convergence algorithm and in combination with allocated cell cluster resources.

Here, in actual application, the control plane signaling processing submodule and the centralized scheduling submodule may be set together to form a control plane signaling processing module. At this point, for the above process, it is:

Among them, in actual application, for the application scenario of 5G network, the solution of this embodiment can be applied to the application scenario of macro base station + micro base station. Correspondingly, at this time, the resources of each cell obtained by the base station are micro Each cell resource corresponding to the base station.

Step 602: The first Cell_MAC unit of the base station allocates radio resources corresponding to services for the UE on the cell resources allocated for the UE based on the cell resources allocated for the UE.

Here, the base station includes more than one Cell_MAC unit; the first Cell_MAC unit is the Cell_MAC unit corresponding to the cell resources allocated for the UE.

When the UE needs to perform services, the decellularization unit allocates corresponding cell resources for the UE by using the cell resources obtained by the base station itself; correspondingly, the first Cell_MAC unit is based on the transmission characteristics of the UE, On the cell resources allocated by the UE, radio resources corresponding to the service are allocated to the UE, so that the allocated radio resources are subsequently used to transmit service data.

The allocated cell resources include the power, identity, channel, etc. of the cell.

Since the control plane signaling processing submodule uses the obtained cell resources to allocate corresponding cell cluster resources to the UE based on a global or local optimal convergence algorithm, all cell resources must be used to allocate corresponding cell cluster resources, and the amount of data It is massive, so the processing speed of this process is relatively slow (such as the RRC process), and the centralized scheduling submodule is combined with the allocated cell cluster resources to allocate corresponding cell resources for the UE, and the amount of data is relatively small.

The service data after the transmission process is sent to the UE through the air interface; the second Cell_MAC unit is a Cell_MAC unit corresponding to the cell resource re-allocated for the UE.
