Technical Field

[0001] The present application belongs to the field of mobile communication technology, and in particular, relates to a network sharing system, method, electronic device and storage medium. Background Art

[0002] The 3rd Generation Partnership Project (3GPP) considered network sharing at the beginning of the formulation of the 5th Generation Mobile Communication Technology (5G) standard, and explicitly required that both the terminal and the network radio access network (RAN) and the core network side support the 5G network sharing function. According to the degree of sharing, network sharing is divided into the following five types: roaming, site sharing, radio access network sharing (Multi-Operator RAN, MORAN), core network sharing (Multi-Operator CoreNetwork, MOCN) and gateway core network sharing (Gateway Core Network, GWCN).

[0003] The existing MOCN network sharing method requires all the hardware on the RAN side to be shared, so it is difficult to achieve sharing by more than two operators in practice, which increases the construction investment. Therefore, the industry urgently needs a network sharing solution that can achieve sharing by more than two operators. Summary of the invention

DETAILED DESCRIPTION

[0012] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0013] The terms "first", "second", etc. in this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in this application represents at least one of the connected objects, and the character " / " generally represents that the front and back associated objects are in an "or" relationship. It should be noted that the data involved in this application are all obtained on the premise of obtaining user authorization.

[0014] Network sharing is divided into the following five types according to the degree of sharing: roaming, site sharing, MORAN, MOCN and GWCN.

[0015] The first one: roaming In this way, an operator has no physical network at all. The cells, base stations and core networks are all rented from others. It only needs to build user management and service platforms. At present, virtual operators between countries and within the country mainly adopt this method, providing services to users by sharing the networks of the three major operators.

[0016] Although this method does not require the effort of building a network and can also quickly carry out business with the help of other people's mature networks, the priority of resource use is inevitably low, and there is no network autonomy.

[0017] The second type: site sharing In this way, the two operators only share the physical site, including: machine room, tower, power supply, antenna system, etc. At present, China Tower adopts this model in China, where the infrastructure is built by China Tower Corporation and then leased to the three major operators, so as to achieve resource sharing and reduce duplicate investment.

[0018] The third type: MORAN This type of sharing is one step closer than site sharing. It also shares the main equipment of the wireless access network, the base station, by sharing the baseband unit (BBU). The BBU is connected to the remote radio unit (RRU) / active antenna unit (AAU) of the same manufacturer. The RRU / AAU is independent for each operator, and each carrier is independently configured and managed. Inside the wireless side 5G base station (the next Generation Node B, gNB), logically independent different cells are used to provide independent use to multiple operators. Although this method is shared, it is not thorough. It only shares the modules inside the base station that are not related to the wireless access resources, while the most critical parts: cells and frequencies are still used by each operator and each one does its own thing. At present, this sharing method has not been adopted in China.

[0019] The fourth type: MOCN This type of sharing is one step closer to MORAN. It not only shares the main equipment of the wireless access network, the base station hardware itself, but also shares the most critical modules related to wireless access resources inside the base station: cells and frequencies. In other words, BBU, RRU / AAU are all shared, and all RAN equipment on the site side is shared. Sharing a certain segment or several segments of carriers from different operators forms a continuous large-bandwidth shared carrier, which can further reduce infrastructure and equipment costs. At present, domestic operators mainly use this mode for sharing.

[0020] Fifth: GWCN This type of sharing goes one step further than MOCN. It not only shares the main equipment of the wireless access network - base station hardware and the most critical modules related to wireless access resources: cells and frequencies, but also some network elements of the core network.

[0021] For the wireless side, GWCN performs the same as MOCN, and both need to consider the resource allocation and management issues within the base station. For the core network, the shared network elements also need to consider the capacity allocation. In addition, the Home Subscriber Server (HSS) for user management is the core of the core network and is not shared. The high-level service platform has different services for specific operators and is not shared. However, considering the independence of domestic operators, even if China Telecom and China Unicom share, the two parties build the core network independently and do not share. Therefore, the sharing method of GWCN is not adopted in China.

[0022] Figure 1 For the existing 5G MOCN network sharing architecture, only the RAN side can be shared in the 5G system. The access and mobility management function (AMF) in the user equipment (UE), RAN and core network should support the ability of operators to use more than one public land mobile network (PLMN) identity (Identity, ID).

[0023] For key technologies and processing procedures in the MOCN network architecture, such as system message broadcasting of shared networks, PLMN list processing, UE network registration, mobility management, network sharing and network slicing, the 3GPP protocol has relevant technical standard descriptions, as follows: 1. System message broadcast If a shared NG-RAN is configured as an available network (including multiple PLMNs and / or multiple SNPNs) for UE selection, each cell in the shared RAN shall include the available operator information in the shared network in the broadcast message. The broadcast system message broadcasts a PLMN ID and / or a subset of PLMN ID + NID and one or more additional parameter sets for each PLMN (such as cell ID, TAC, CAG identifier, etc.).

[0024] When the UE accesses a shared cell, the system message broadcast in the shared cell indicates the TAC and cell identifier (NR Cell Identify, NCI) for each subset of the PLMN, and each cell of each PLMN provides a TAC and a cell NCI. Through SIB1, it can be known that the gNB indicates the TAC and NCI for each subset of the PLMN. The specific description is as follows Figure 2 As shown, the UE can obtain a PLMN identification information list (PLMN-Identity InfoList) consisting of 1 to 12 PLMN-IdentiyInfo from SIB1. Each PLMN-IdentiyInfo contains a TAC, an NCI and a plmn-IdentityList consisting of 1 to 12 PLMN-Identities, that is, one SIB1 information element can obtain up to 12 different PLMN-Identities corresponding to different cell identities. Of course, different PLMN-Identities can also be configured for one cell Identity.

[0025] 2.PLMN list processing The AMF prepares a list of PLMN IDs suitable as target PLMNs and uses them for idle mode cell selection (cell reselection) and handover and RRC connection release with redirection. The AMF provides the following functions: 1) Provide the UE with a list of PLMNs, which the UE should consider as equivalent to the serving PLMN[8]; 2) Provide a priority list of allowed PLMNs to NR-RAN. When prioritizing these PLMNs, the AMF may consider the following information: UE's HPLMN, serving PLMN, preferred target PLMN (e.g. based on the last used EPS PLMN) or operator's policy.

[0026] 3.UE network registration When a UE of a certain operator subscribes to a core network corresponding to a certain operator of a shared network, the UE should be able to select the subscribed core network in the coverage area of ​​the shared network and receive subscribed services from the core network.

[0027] In a shared NR-RAN, each cell should include the PLMN-ID of the available core network in the shared network in the broadcast system information. For example, if the shared network is composed of China Mobile, China Telecom and China Unicom, the PLMN-ID of the core network of China Mobile, China Telecom and China Unicom should be included in the broadcast system information.

[0028] When the UE performs an initial registration, an available PLMN shall be selected to serve the UE. The UE uses all received broadcast PLMN-IDs during the PLMN selection / reselection process. The UE shall inform the NG-RAN of the selected PLMN so that the NG-RAN can route correctly. At the same time, the NG-RAN shall inform the core network of the selected PLMN. Since access can be made using the broadcast PLMN-ID in the system information. For any network, after initial registration to a shared network, and while remaining served by the shared network, the network selection process may cause the UE to perform reselection of another available PLMN.

[0029] 4. Mobility Management The NG-RAN uses the selected PLMN (provided by the UE at RRC establishment, or by the AMF / source NG-RAN at N2 / Xn handover, where N2 is the interface between the NG-RAN and the AMF, and Xn is the interface between the NG-RAN and the NG-RAN) to appropriately select target cells for future handovers (and general radio resources), and the UE should not be moved, such as by handover, to another available PLMN as long as the network-selected PLMN is available to serve the UE's location.

[0030] In case of handover or network control release to a shared network: 1) When multiple PLMN IDs are broadcasted in a cell selected by the NG-RAN, the NG-RAN shall select a target PLMN taking into account the priority list of PLMN IDs provided from the mobility restriction list of the AMF.

[0031] 2) For an Xn-based handover procedure, the source NG-RAN indicates the selected PLMN ID to the target NG-RAN 3) For N2 based handover procedure, the NG-RAN indicates to the AMF a selected PLMN ID as part of the TAI sent in the "Handover Request" message. The source AMF uses the TAI information provided by the source NG-RAN to select the target AMF / MME. The source AMF shall forward the selected PLMN ID to the target AMF / MME. The target AMF / MME indicates the selected PLMN ID to the target NG-RAN / eNB so that the target NG-RAN / eNB can appropriately select the target cell for future handovers.

[0032] The change of serving PLMN is indicated to the UE via 5G-GUTI as part of the UE registration.

[0033] 5. Network sharing and network slicing Network slicing is defined in PLMN, while network sharing is sharing between different PLMNs. In the case of network sharing, each PLMN in the shared NG-RAN can define and support a PLMN-specific slice set supported by the non-shared NG-RAN.

[0034] The existing MOCN network sharing method requires all the hardware on the RAN side to be shared, so it is difficult to achieve sharing by more than two operators in practice, which increases construction investment. For example, the current network sharing between domestic operators is mainly shared by China Mobile and China Telecom and China Unicom, both of which adopt the MOCN method. Among them, China Unicom and China Telecom are built in different areas. Whoever builds it will invest, maintain and bear the network operation costs; each of the two companies only needs to build half of the 5G base stations and share the sites they have built with each other. The operation and maintenance of the sites are all handled by the main construction party; the 5G spectrum resources of both parties are shared, and the core network is built independently without sharing. China Radio and Television and China Mobile share through the MOCN method. China Radio and Television allows China Mobile to use the 700M frequency band, and China Mobile builds its own 700M network and 2.6GHz network to share with China Radio and Television through the MOCN method. As the investment in 5G frequency band network construction continues to increase, operators' investment in 5G networks is becoming increasingly tight, and they are also willing to further reduce construction investment. Therefore, in some scenarios, there is a probability of sharing by more than two operators; in addition, considering the operators' emphasis on the ownership of base station equipment assets, for operators that have not signed and reviewed cooperative sharing, they will not agree to share core network and BBU equipment with other operators.

[0035] Based on this, the present application proposes a network sharing system, method, electronic device and storage medium to solve the problem in related technologies that it is difficult to achieve sharing by more than two operators, which increases construction investment.

[0036] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0037] Figure 3 A schematic diagram of a network sharing system provided by an embodiment of the present application. Figure 3 As shown, the network sharing system of the embodiment of the present application may specifically include: Multiple non-shared baseband units BBU31 corresponding to multiple operators ( Figure 3 In the figure, operator A corresponds to BBU1 and operator B corresponds to BBU2 as an example), as well as a digital aggregation unit (DAU) 32 and a medium radio frequency device 33 shared by multiple operators.

[0038] Among them, BBU31 is managed and maintained by the corresponding operator, and the assets belong to the operator. DAU32 and medium-frequency equipment 33 are built by third-party tower operators, and the assets also belong to the third-party tower operators.

[0039] Each BBU31 includes a main control and a baseband (or baseband board). The network management of the corresponding operator is responsible for the management and maintenance of the BBU31. Figure 3 In the figure, it is shown as an example that the master control of BBU A corresponds to the network management A, and the master control of BBU B corresponds to the network management B). BBU31 is connected to the DAU32 through the baseband.

[0040] The radio frequency device 33 at least includes a physical radio frequency unit (physical RRU, pRRU).

[0041] DAU32 is used to: set the corresponding virtual radio frequency unit VRRU identifier (VRRU-id) for each pRRU set according to the pRRU sets and cell parameters planned by each operator for each cell, set parameters for each pRRU in the corresponding pRRU set according to the cell parameters, and communicate with each BBU31 and each pRRU based on the VRRU identifier.

[0042] The number of cells planned by each operator is determined by each operator according to its own coverage and coverage capacity requirements. Specifically, each operator plans according to its own coverage and coverage capacity requirements, as well as the coverage and coverage capacity of each pRRU, and obtains the number of cells to be planned, as well as the pRRU set and cell parameters planned for each cell.

[0043] Taking operator A, operator B, cell 1 to cell 3, pRRU1 to pRRU6 as an example, the planning relationship can be shown in Table 1: Table 1 Planning relationship

[0044] The pRRUs in the pRRU set are the pRRU resources planned for the corresponding cell. For example, the pRRU set A1 {pRRU1, pRRU2} indicates that the pRRU resources planned by operator A for cell 1 are pRRU1 and pRRU2.

[0045] The parameters of a cell are used to define the specific physical resources and configuration information of the cell, and may include but are not limited to at least one of the following parameters: cell identifier (CELL-id), frequency band (Freq-Band), bandwidth (Bandwidth), subcarrier spacing, time slot ratio, number of transceiver units (TRX) and duplex mode (Duplex Mode), etc.

[0046] DAU32 sets a corresponding virtual radio unit VRRU identifier (VRRU-id) for each pRRU set according to the pRRU set and cell parameters planned by each operator for each cell, as shown in Table 2: Table 2 VRRU-id corresponding to pRRU set

[0047] DAU32 also sets parameters for each pRRU in the corresponding pRRU set according to the parameters of each cell, as shown in Table 3 below: Table 3 Parameter settings for each pRRU

[0048] It should be noted here that the set pRRU parameters do not include parameters in the cell parameters that are not used by the pRRU, such as subcarrier spacing, time slot ratio, etc.

[0049] Furthermore, the intermediate radio frequency device 33 may also include a hub (HUB) for connecting the DAU 32 and the pRRU, for example Figure 3 In the example, HUB1 is used to connect DAU32 and pRRU1, and DAU32 and pRRU2.

[0050] Further, such as Figure 3 As shown, the network sharing system of the embodiment of the present application may also include an aggregation management unit (Aggregation Management Unit, AMU), and the network manager of the remote aggregation center (RAC) of the third-party tower operator is responsible for managing and maintaining the RAC.

[0051] The DAU 32 communicates with each BBU 31 and each pRRU based on each VRRU identifier.

[0052] Specifically, BBU31 sends and receives data through a fiber optic interface of the baseband board, such as the Common Protocol Radio Interface port (CPRI port), and DAU32 sends and receives data through the uplink port (DAU port). Taking the example of BBU31 sending data to DAU, BBU31 sends data to DAU32 through the fiber optic interface, and DAU receives the data sent by BBU31 through the uplink port. DAU matches the VRRU identifier (VRRU-id) corresponding to the data received through the uplink port with the VRRU identifier (VRRU-id) configured for the uplink port, and determines whether the uplink port for receiving the data is correct based on the matching result. If the matching result is a match, it is determined that the uplink port for receiving the data is correct, and the received data is sent to the corresponding pRRU; if the matching result is a mismatch, it is determined that the uplink port for receiving the data is incorrect, and the received data is not sent to the pRRU.

[0053] After adopting the network sharing system of the embodiment of the present application, except for BBU31, all other RAN devices on the site side are shared. BBU31 is still managed by each operator, and each BBU31 completes the configuration of the cell and the corresponding mid-RF resources. In addition, in order to ensure that the BBU31 of different operators can be sent to the same RRU or HUB and RRU of the expanded base station after configuration, the embodiment of the present application adds a network element DAU32 to the network sharing system, which can realize the function of passing the configuration of multiple BBU31 to the shared mid-RF device 33. In this way, it can realize the equipment sharing of more than two operators, further reduce the construction cost, and enable each operator to independently operate its own network.

[0054] by Figure 3 For example, the total resource specifications of the HUB and pRRU downstream of DAU32 can be shared by the BBU31 upstream of DAU32. Therefore, the allocation of resource specifications of each BBU31 needs to be configured on the DAU32 side according to each upstream port. BBU31 needs to be configured within the resource slice specifications sent by DAU32 and cannot exceed the specifications.

[0055] In order to ensure that the BBU31 configuration of each operator can correspond one-to-one with the HUB and pRRU resources, the embodiment of the present application proposes a new configuration method, by virtualizing the HUB and pRRU resources, represented here by VRRU, the resource specifications of BBU31 and DAU32 are both corresponded by a VRRU. On the BBU31 side, VRRU represents a group of medium radio frequency resources associated with the logical cell configured on BBU31, and on the DAU32 side, VRRU represents a specific group of HUB+pRRU resources.

[0056] Therefore, when configuring a co-built and shared cell, you need to plan in advance and write the planned content into the VRRU. The planned content includes: 1) Cell coverage planning, that is, the relationship between the cell parameters NRDUCELL and the pRRU set. NRDUCELL is configured on the BBU31 side, and the pRRU set is configured on the DAU32 side. NRDUCELL-VRRU-id is used for association. Therefore, NRDUCELL-VRRU-id needs to be aligned with BBU31 and DAU32. Each VRRU on the DAU32 side corresponds to a RF combiner group. If one NRDUCELL is to be equipped with multiple RF combiner groups, multiple VRRUs need to be configured.

[0057] 2) The cell specifications (including frequency band, bandwidth, number of TRXs and duplex mode) of the DAU32 and BBU31 are configured in NRDUCELL on the BBU31 side and VRRU-Radio-resource on the DAU32 side. Only when the corresponding cell specifications are consistent, will the DAU32 establish the corresponding carrier resources.

[0058] 3) The docking port between VRRU of BBU31 and VRRU of DAU32. VRRU data of an NRDUCELL on the BBU31 side receives and sends data from an optical fiber interface of the baseband board. VRRU data of DAU32 receives and sends data from an uplink port of DAU32. DAU32 receives the VRRU-id sent from BBU31 according to the DAU port. Use the VRRU-DAU-port configuration to check to ensure that the VRRU-id received from BBU31 is consistent with the VRRU-id configured on this uplink port.

[0059] The configuration relationship is shown in Table 4 below: Table 4 Configuration relationship

[0060] Example: BBU31 side: / / Add a vrru configuration on the BBU side add nrducell-vrru: slot=slot nrducell-id=nrducell-id nrducell-vrru-id=vrru-id DAU32 side: / / Add a vrru configuration on the DAU side add vrru-radio-resource: nrducell-vrru-id=**; trxnum=**; cell-bandwidth=**; frequency-band=**; duplex-mode=**; / / Add an rru group on the DAU side add rru-group:group-id=group-id / / Add the RRU device to an RRU group on the DAU side add rru-groupeqm:group-id=group-id rcn=rcn / / Add an rru group on the DAU side corresponding to a vrru add vrru-rru-group: vrru-id=vrru-id vrru-coverage-id=vrru-coverage-idgroup-id=group-id max-transmit-power=max-transmit-power In summary, the network sharing system of the embodiment of the present application includes multiple non-shared baseband units BBU corresponding to multiple operators; a digital aggregation unit DAU and a medium radio frequency device shared by multiple operators, the medium radio frequency device includes a physical radio frequency unit pRRU, and the DAU is used to: set a corresponding virtual radio frequency unit VRRU identifier for each pRRU set according to the pRRU set and cell parameters planned by each operator for each cell, and set parameters for each pRRU in the corresponding pRRU set according to the cell parameters, and communicate with each BBU and each pRRU based on the VRRU identifier. The embodiment of the present application proposes a new network sharing system, introduces a DAU and VRRU configuration method, and separates the configuration of logical cells from the configuration of actual medium radio frequency resources, so that in a co-construction and sharing scenario, each operator has the right to configure the cell, which not only solves the co-construction and sharing problem of more than two operators and reduces construction investment, but also ensures that each operator has the configuration of radio frequency resources. At the same time, third-party tower operators can also dynamically adjust the medium radio frequency resources allocated to each operator through DAU. Based on the network sharing system of the above embodiment, the present application embodiment also provides a network sharing method. Figure 4 As shown, the network sharing method of the embodiment of the present application is applied to the DAU of the network sharing system of the above embodiment, and the network sharing system includes: multiple non-shared BBUs corresponding to multiple operators; DAUs and medium radio frequency devices shared by multiple operators, and the medium radio frequency devices include pRRUs. The network sharing method may specifically include the following steps: S401, according to the pRRU sets and cell parameters planned by each operator for each cell, a corresponding VRRU identifier is set for each pRRU set.

[0061] S402: Setting parameters for each pRRU in the corresponding pRRU set according to the cell parameters.

[0062] S403: Communicate with each BBU and each pRRU based on the VRRU identifier.

[0063] Furthermore, the BBU sends and receives data through a fiber optic interface of the baseband board, and the DAU sends and receives data through an uplink port. The network sharing method may also include: matching the VRRU identifier corresponding to the data sent by the fiber optic interface received through the uplink port with the VRRU identifier of the uplink port; and determining whether the uplink port receiving the data is correct based on the matching result.

[0064] To clearly illustrate the network sharing method of the embodiment of the present application, Figure 5 The overall process of the network sharing method in the embodiment of the present application is described in detail. Figure 5 As shown, the network sharing method of the embodiment of the present application includes the following steps: S501: According to the pRRU sets and cell parameters planned by each operator for each cell, a corresponding VRRU identifier is set for each pRRU set.

[0065] S502: Set parameters for each pRRU in the corresponding pRRU set according to the cell parameters.

[0066] S503, determine whether the VRRU identifier corresponding to the data sent by the optical fiber interface received through the uplink port matches the VRRU identifier of the uplink port. If yes, execute step S504. If no, execute step S505.

[0067] S504, determining that the uplink port receiving the data is correct, and sending the received data to the corresponding pRRU.

[0068] S505, determining that the uplink port for receiving the data is incorrect, and not sending the received data to the pRRU.

[0069] In the embodiment of the present application, the specific process of the network sharing method in the embodiment of the present application can refer to the relevant description in the above-mentioned network sharing system embodiment, which will not be repeated here.

[0070] In summary, the network sharing method of the embodiment of the present application is applied to a new network sharing system, and a DAU and VRRU configuration method is introduced. By separating the configuration of the logical cell from the configuration of the actual RF resources, each operator has the right to configure the cell in the co-construction and sharing scenario, which not only solves the co-construction and sharing problem of more than two operators and reduces the construction investment, but also ensures that each operator has the configuration of RF resources. At the same time, the third-party tower operator can also dynamically adjust the RF resources allocated to each operator through DAU.
