Description

Multi-mode deep fusion method, device and base station

Technical field

The present application relates to, but is not limited to, the field of communication technologies, and in particular, to a multi-mode deep fusion method, apparatus, and base station.

Background technique

TDD (Time Division Duplexing) and FDD (Frequency Division Duplexing) are two technical modes under the LTE (Long Term Evolution) standard. These two technical modes use different channels when transmitting data. FDD utilizes uplink and downlink frequency transmission. When FDD supports symmetric services, it can make full use of uplink and downlink spectrum, but when it supports asymmetric services, spectrum utilization. Will be greatly reduced. TDD uses one frequency to set the uplink and downlink transmission time, but in order to resist interference, there may be waste of resources.

The combination of FDD and TDD can complement each other's advantages and disadvantages, and the two modes aggregate spectrum to achieve higher data rate and throughput. At present, some operators have begun to consider converged networking. From the perspective of the deployment of major operators and national policies, the integration of the two is a big trend.

At present, there are two main ways to integrate FDD and TDD:

1. TDD and FDD are deployed on an eNodeB (Evolved Node B, the evolved Node B), which is a site on the hardware, but logically still two sites. There are two IP addresses, a base station ID (identification), an S1 link, and an X2 link, which respectively characterize TDD and FDD. The internal deployment of the base station is an FDD and TDD common signaling resource board, but each has an independent baseband resource board. In this scenario, the IP (Internet Protocol) address and the SCTP (Stream Control Transmission Protocol) link and the base station ID resource are greatly wasted. The simulated TDD base station and the FDD base station can only reach the original single. Half of the total capacity of the die design.

2. TDD and FDD are deployed on an eNodeB, and the common processing module is extracted for the data configuration module, protocol layer RRC (Radio Resource Control), GTPU (GPRS Tunnelling Protocol for the Userplane). adaptation. Each cell-level function maintains the original design, abstracting an adaptation module for With the FDD/TDD design incompatibility problem, in this scenario, the processing is complicated, and an additional processing module is required, the development workload is large, the software version maintenance cost is high, the performance is poor, and the efficiency is low.

The essence of the above two schemes is that TDD and FDD use two sets of processing methods. With the integration of FDD and TDD, it is necessary to find a simple and effective implementation method.

Moreover, the total capacity of the base station can be dynamically used, and the processing is simple and effective. The implementation process of the embodiments of the present invention will be described in detail below through several embodiments.

In the first embodiment of the present invention, a base station is configured, the base station is configured to have no mode attribute, and each cell in the base station is configured to have a mode attribute. In this embodiment, the network management is in the network. The base station and the cell are configured, and the configuration data is sent to the base station, and the base station receives the configuration data and stores it.

The configuration principle of the network management system is that the base station does not have the mode attribute, that is, the configured base station level configuration data is a configuration data that does not distinguish between modes. In an embodiment, the configured base station level configuration data includes a base station ID, a PLMN (Public Land Mobile Network) ID, a base station IP address, and S1 port link configuration information.

When the network management system is configured, the configuration principle is that the cell has a mode attribute, that is, the configured cell configuration data is cell level configuration data related to the mode to which the cell belongs. In the embodiment of the present invention, the modes include, but are not limited to, a TDD mode and an FDD mode. When the mode includes the TDD mode and the FDD mode, if the cell belongs to the TDD mode, the configured cell configuration data is cell-level configuration data specific to the TDD mode, including but not limited to: uplink-downlink subframe matching information, special subframe. Mode parameters, etc. If the cell belongs to the FDD mode, the configured cell configuration data is cell-level configuration data specific to the FDD mode, including but not limited to: a central carrier frequency of the uplink of the cell, a bandwidth parameter of the uplink system, and the like.

Based on the foregoing configuration, the base station in the embodiment of the present invention may implement unified processing of signaling and a differentiated mode for resource configuration without distinguishing modes. As shown in Figure 1, the base station in this embodiment includes: a control signaling board 110 and a baseband resource board 120;

The control signaling board 110 is configured to carry the network-wide unique identifier of the base station when performing interaction with the mobile management entity MME or the neighboring base station, and use the unified allocation mode when the UE accesses any cell. The UE allocates the unique identifier of the UE, and stores the mapping relationship between the unique identifier information of the UE and the current serving cell of the UE and the mode to which the UE belongs; and carries the unique identifier of the UE when performing the UE-level signaling interaction with the MME or the neighboring base station. And querying the mapping relationship according to the unique identifier of the UE, determining a mode of the current serving cell of the UE, and configuring the baseband resource board 120 according to the determined mode and the cell configuration data of the serving cell;

The baseband resource board 120 is configured to configure a baseband resource for the UE according to the configuration of the control signaling board 110.

In the embodiment of the present invention, the entire network unique identifier of the base station includes: a base station ID and a PLMN ID.

In an embodiment of the present invention, the control signaling board 110 fills the entire network unique identifier of the base station in a global eNodeB identifier field in the base station level signaling, and performs base station level signaling with the MME or the neighboring base station. The UE and the neighboring base station perform UE-level signaling interaction with the MME or the neighboring base station as the unique identifier of the UE in the UE-level signaling on the S1 port or the X2 port of the UE.

In an embodiment of the present invention, the baseband resource board may be a one supporting multiple modes. The baseband resource board may also be a baseband resource board supporting a single mode. When the baseband resource board supports a single mode, one or more baseband resource boards corresponding to the mode are provided for each mode.

In the embodiment of the present invention, when equipped with multiple baseband resource boards supporting different modes:

The control signaling board 110 determines a baseband resource board for configuring a baseband resource according to a mode used by the current serving cell of the UE; and extracts cell configuration data of the current serving cell, and configures the determined baseband resource board, and the baseband resource board is configured according to the baseband resource board. The configuration of the control signaling board 110 configures baseband resources for the UE.

In an embodiment of the present invention, the control signaling board 110 is further configured to: send a cell broadcast according to a mode to which the cell belongs; and the cell broadcast carries the network-wide unique identifier of the base station and mode information of a mode to which the cell belongs. .

In an embodiment of the present invention, the control signaling board 110 is further configured to: when receiving the measurement report sent by the UE, if the cell corresponding to the measurement object in the measurement report and the current cell of the UE are different in the base station The mode cell, after performing the measurement parameter admission and configuration, selects the cell corresponding to the measurement object as the target cell to be handed over, and sends an RRC reconfiguration message to the UE, where the reconfiguration message carries the cell data in the mode to which the target cell belongs.

In summary, in the convergence scheme proposed in this embodiment, the signaling processing flow of the control signaling board is unified, and the mode processing is no longer distinguished; and the baseband resources of all the related processes of the cell need to be differentially processed according to the cell mode, which is simple and effective. A multi-mode deep fusion.

In order to clarify the embodiment of the present invention, the TDD mode and the FDD mode deep fusion are taken as an example, and the base station architecture described in FIG. 1 is used to describe the process of implementing TDD and FDD deep fusion by the base station.

In this embodiment, the process of implementing deep integration of TDD and FDD by the base station includes:

Step 1: The base station data configuration background (network management) configures the base station data and configures the cell data. The configuration principle is that the base station does not have the attribute of the mode, and the cell has the mode attribute.

When the base station data configuration is configured in the background, the base station ID, the base station IP address, the PLMN ID, the link configuration information of the S1 interface, the link configuration information of the X2 interface, and the like are configured, that is, the parameter configuration related to the base station level is configured. Use one copy.

When configuring cell data, configure a TDD or FDD cell according to the networking situation. The configuration of different parameters of the mode is moved to the cell-related configuration. For the TDD cell, the uplink and downlink subframe matching information and the special subframe mode parameters are configured; for the FDD cell, the central carrier frequency of the uplink of the cell is configured. , uplink system frequency domain bandwidth parameters. At this time, there will be an FDD mode cell under one base station, and there will also be a TDD mode cell.

Step 2: The control signaling board mainly carries the base station data configuration management and signaling flow control, and the TDD and FDD processing processes are unified. The control signaling board stores base station and cell related configuration information. When interacting with the MME or the neighboring eNodeB, for non-UE level signaling (ie, base station level signaling), the base station information is mainly identified by the base station ID and the PLMN ID, and now the different mode base station ID and the PLMN ID are the same, so the non-UE The level signaling process is unified; the UE level signaling is identified by the EnbUeId allocated by the base station to the UE. In the deep convergence architecture, the control signaling board allocates the EnbUeId for the UEs of different modes using the same rule, so the UE level letter Make process processing uniform. For the transport layer link of the MME or the neighboring base station, since the IP presentation of the base station is one, the transmission is uniformly processed.

Step 3: The original processing mode of the baseband resource board is unchanged. Protocol layer PHY (physical layer), MAC (Media Access Control, media access control layer), RLC (Radio Link Control, Radio Link Control Protocol), PDCP (Packet Data Convergence Protocol) module are bearers On the baseband resource board. The control signaling board identifies the mode information of the cell and the UE accessing the cell that the UE accesses according to the EnbUeId allocated to the UE, determines the baseband resource board that needs to be configured according to the mode information of the access cell, and invokes the configured cell data. The baseband resource board is configured, and the baseband resource board is processed according to the mode in which the UE accesses different cells.

It can be seen from steps 2 and 3 that under the new architecture, the baseband resources of all the cell-related processes need to be differentially processed, and the processes related to the base station can be shared. Because the process involving air interface transmission needs to have a clear baseband resource configuration, it is necessary to identify FDD or TDD, and perform different parameter setting and message content, and message processing mode (for example, for the mode of the cell accessed by the UE, data is performed. The choice of modem. The process involving the base station does not involve the baseband resource attribute, so it can be shared.

In the new architecture, the UE access identification mode is: when the UE accesses, the base station can obtain the mode corresponding to the cell according to the cell ID accessed by the UE, and the base station allocates an EnbUeId to the UE, and the base station stores the UE context-related information and the EnbUeId. When the UE is in connection with the base station, with the MME Alternatively, the EnbUeId may be used to match the corresponding UE context information.

The implementation process of the embodiments of the present invention will be described in more detail below with reference to several application examples.

Application example 1:

This embodiment provides an implementation manner in which a base station implements deep fusion in deep integration of FDD and TDD, including:

Step 1: According to the deployment of the network, the base station data configuration background allocates a base station level data such as an IP address and a base station ID to the base station, configures S1 coupling and X2 coupling, and configures a TDD or FDD cell and a mode-specific parameter associated with the cell. .

Step 2: After receiving the configuration data of the base station, the control signaling board processes the interaction between the S1 interface and the X2 interface at the base station level and the UE level. Handling the signaling process of the RRC layer, including:

1) For base station level signaling of the S1 port, the MME identifies the base station by the eNodeB ID and the PLMN ID. The base station level signaling includes messages such as S1SETUP REQUEST/S1SETUP RESPONSE/ENB CONFIGURATION UPDAT. For example, when the S1 port is established, the base station sends an S1 SETUP REQUEST, which carries the Global eNB ID, which is composed of the eNodeB ID and the base station PLMN ID. After receiving the MME, the MME performs corresponding processing and simultaneously returns S1SETUP RESPONSE to the corresponding base station. After deep integration, the base station data configuration background allocates an eNodeB ID and a PLMN ID, so different modes can be processed uniformly.

2) For the UE-level signaling of the S1 interface, the UE accesses or the S1 handover, and the MME and the base station perform the transmission interaction through the MME UE S1AP ID and the eNB UE S1AP ID identifier. The base station allocates an EnbUeId to the UE, and the ID also serves as the unique identifier eNB UE S1AP ID for interaction with the MME, and the MME allocates the MME UE S1AP ID to the UE. The UE-level signaling of the S1 port carries the two identifiers, and the UE can be uniquely identified. The identifier can be mapped to the corresponding cell, and the corresponding mode information of the cell is determined. The UE level signaling includes messages such as INITIAL UE MESSAGE/INITIAL CONTEXT SETUP REQUEST/INITIAL CONTEXT SETUP RESPONSE/HANDOVER REQUIRED. For example, the first S1 message sent by the base station, INITIAL UE MESSAGE, carries the eNB UE S1AP ID and E-UTRAN CGI (composed of the base station PLMN, eNodeB ID, and cell ID). After receiving the MME, the MME performs corresponding processing and allocates an MME UE S1AP ID to the UE, and sends an INITIAL CONTEXT SETUP REQUEST to the base station, carrying the MME UE S1AP ID. And the eNB UE S1AP ID, after receiving by the base station, the MME UE S1AP ID and the eNB UE S1AP ID can be matched to the corresponding UE.

3) For the base station level signaling of the X2 port, the base station performs transmission interaction between the eNodeB ID and the PLMN ID identifier. The base station level signaling includes messages such as X2 SETUP REQUEST/X2 SETUP RESPONSE/ENB CONFIGURATION UPDATE. For example, the X2 port establishes a message X2 SETUP REQUEST, which carries the Global eNB ID, and after receiving the corresponding base station, performs corresponding processing, and returns a message X2 SETUP RESPONSE to the corresponding base station. Therefore, different modes can be processed uniformly.

4) For the UE-level signaling of the X2 port, the base stations perform transmission interaction through the X2 UE S1AP ID identifier. The base station allocates an EnbUeId to the UE, and the ID also serves as a unique identifier for the interaction between the base stations. The X2 UE S1AP ID is used to carry the received UE signaling, and carries the identifier. For the received UE level signaling, the identifier can be mapped to the corresponding The cell can determine the corresponding mode information of the cell. UE level signaling includes messages such as HANDOVER REQUEST/HANDOVER REQUEST ACKNOWLEDGE/HANDOVER CANCEL. For example, the UE-level signaling HANDOVER REQUEST, the handover source side sends a HANDOVER REQUEST, and carries the EnbUeId allocated by the local base station to the UE as the Old eNB UE X2AP ID, and the handover target base station receives the message for corresponding processing, and allocates the EnbUeId to the UE as the New eNB. The UE X2AP ID, the target side replies to the handover original side HANDOVER REQUEST ACKNOWLEDGE, carrying the Old eNB UE X2AP ID and the New eNB UE X2AP ID.

Step 3: The control signaling board obtains the relevant configuration of the cell and saves the related information of the cell. After the cell is established, the broadcast information is filled in according to different modes to which the cell belongs, and the broadcast information is sent. For example, the TDD cell, the SystemInformationBlockType1 will fill in the cell TDD-Config. For a single-mode TDD or FDD UE, the UE receives the cell broadcast of the corresponding mode according to the registered operator, and for the dual-mode UE, according to the signal strength of the cell, one of the cells is selected to initiate random access, and the RRC layer receives the RRC of the UE access. The connection request acquires corresponding mode information of the cell according to the accessed cell information.

Step 4: The control signaling board allocates an EnbUeId to the accessed UE, and saves the UE context information, and then the mode information of the UE access can be uniquely determined according to the ID. According to the mapping relationship, the control signaling board can send different mode messages to the corresponding baseband resource board. During the UE access process, the base station needs to configure the radio resource and other related information for the UE. When acquiring the radio resource information, the unified processing module obtains parameters of different modes, for example, uplink and downlink subframe scheduling of the TDD.

It should be pointed out that the above-mentioned "steps" do not indicate the order of execution.

Application example 2:

This embodiment provides the behavior of UE access in the FDD and TDD deep convergence scenario:

Step 1: For a single-mode UE, the UE receives a broadcast of the corresponding cell according to the registered operator information. For the dual-mode UE, the UE selects a cell with a good signal to initiate a random access procedure according to the strength of the received signal.

Step 2: There are TDD cell A and FDD cell B in the station. The UE accesses the TDD cell A, and the control signaling board receives the RRCConnectionRequest sent by the UE. The base station allocates a unique identifier of the UE to the UE, and the base station maintains the data correspondence between the unique identifier 0 of the UE and the TDD cell A and the cell mode. The UE accesses the FDD cell B, and the control signaling board receives the RRCConnectionRequest sent by the UE, and the base station allocates a unique identifier of the UE to the UE, and the base station maintains the unique identifier 1 of the UE and the data corresponding to the FDD cell B and the cell mode. Relationship; the base station maintains a mapping table between the unique identifier of the base station and the cell. The control signaling board is configured with a baseband resource board, which carries cell related information, and the baseband resource board allocates corresponding resources to the UE. For TDD, uplink and downlink are scheduled according to time allocation in the same frequency band, while FDD is scheduled for different frequency bands of uplink and downlink. After the baseband resource board is configured, the control signaling board sends an RRCConnectionSetup message to the UE. When the message is set up, the radio resource related information is not filled in the same mode. The cell in the differentiated mode is obtained according to the cell accessed by the UE. Parameter information. After receiving the RRCConnectionSetup, the UE sends an RRCConnectionSetupComplete to the base station.

Step 3: After receiving the RRCConnectionSetupComplete, the RRC layer performs the S1 interface routing. After the RRC layer is selected, the first S1 interface message InitUeMessage is set up, and the message carries the unique identifier EnbUeId of the UE on the base station side, and is sent to the MME. In the interaction with the MME, there is no need to distinguish the mode of the cell, and the processing flow is unified. For the signaling and bearer transmission of the S1 port, Through IP transmission, the S1 interface user plane and control plane are based on IP transmission. The difference is that the control plane adopts SCTP at the IP layer to provide reliable transmission for wireless network layer signaling. Currently, different modes use the same IP, so the transmission is a unified processing flow.

Application example 3:

This embodiment provides a behavior for switching between different mode cells in a UE station in a scenario of FDD and TDD deep convergence:

Step 1: The base station sends TDD and FDD cell broadcasts. The dual-mode UE initially accesses the FDD cell, and the base station sends a measurement configuration to the UE, and carries the TDD neighbor information. The UE measures the neighboring cell signal to the base cell signal, and after the measurement threshold is met, the UE sends a measurement report to the base station.

Step 2: After receiving the measurement report sent by the terminal UE, the RRC layer selects the target TDD cell that the UE needs to switch after the measurement parameter is received and configured, and the base station sends an RRC reconfiguration message to the UE, and the reconfiguration message carries the TDD-specific parameters: tdd-AckNackFeedbackMode, srs-MaxUpPts, TDD-Config, etc. in SoundingRS-UL-ConfigCommon.

Step 3: After receiving the RRC reconfiguration message, the UE initiates a random access to the TDD cell, and the random access is successful, and the UE sends the RRC reconfiguration completion to the base station.

In summary, the TDD and FDD deep fusion scheme described in the embodiment of the present invention is compared with the traditional coupling method:

From the operator's point of view, it saves resources for operators. After large-scale commercial use of LTE, IP resources are limited and IP is combined into one, which saves operators' IP resources. The SCTP link with the MME is saved in half. At the same time, through the fusion mode of the patent, the single mode scenario can be compatible, and the single mode or the mixed mode uses the manner described in the solution, which greatly reduces the maintenance cost of the operator and improves the performance of the base station.

From the user's point of view, the handover success rate, re-establishment success rate and quality of service are improved. As an independent site, only inter-station switching and re-establishment can be performed between different modes. After the fusion, switching between the TDD and FDD in the station and re-establishment can be performed.

From the perspective of the equipment manufacturer, the implementation method is simple and effective, and only needs to change the relevant module of the control signaling board for adaptation, and no other changes are required. At the same time, the capacity of the system increases the number of users. The original base station halved the capacity of both FDD and TDD. After the integration, the users of the mixed mode and single mode The number specifications are the same.

Step 22: When the UE accesses an arbitrary cell, the base station allocates a unique identifier of the UE to the UE by using a unified allocation manner, and stores a mapping relationship between the unique identifier information of the UE and the current serving cell of the UE and the mode to which the cell belongs.

Step 23: When the base station performs UE-level signaling interaction with the MME or the neighboring base station, the base station carries the unique identifier of the UE.

Step 24: When the resource is configured, the base station queries the mapping relationship according to the unique identifier of the UE, determines the mode of the current serving cell of the UE, and configures the UE according to the current mode of the serving cell and the cell configuration data of the serving cell.
