Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the background art, after a base station adds a different system cell as a neighboring cell of the base station through different system ANR, when a UE in the different system cell needs to initiate a voice service, CSFB cannot be performed. This is because, although the inter-system cell is added as a neighboring cell, it is not possible to know a Mobile Switching Center (MSC) corresponding to the inter-system cell, and thus it is not possible to drop the traffic in the LTE network back to the 2G or 3G network. At present, in order to solve this problem, one MSC can be manually configured as an MSC for service fallback, however, this method is troublesome, and brings a large manual maintenance cost.
In the present application, the above problems are fully considered, and the network configuration data in the control range of the centralized control device, including the MSC corresponding to each cell, can be embodied by a Mobile Switching center identifier (MSCID for short). After a base station automatically adds a certain inter-system cell as an adjacent cell, the MSC corresponding to the inter-system cell can be known in a manner of querying a centralized control device, so that CSFB is realized when the UE in the inter-system cell needs to initiate a voice service.
The centralized control device is a management device for coordinating the operation of a plurality of base stations within its control range. It can be located in core network or access network; and the functions of maintaining network configuration data and exchanging MSC information with the base station can be added to the existing equipment (e.g. mobility management entity MME or network management equipment) with centralized control function. Or a centralized control device can be independently set up to realize the functions of maintaining network configuration data and exchanging MSC information with the base station. In summary, the embodiment of the present invention does not set any limitation to the implementation of the centralized control device.
In addition, the centralized control equipment can actively acquire the configuration data of all cells in the control range of the centralized control equipment through configuration synchronization, also can acquire the configuration data of all cells in the control range of the centralized control equipment through the form of active reporting of each network element, and also can acquire the configuration data of all cells in the control range of the centralized control equipment through a manual input mode, and the data should be stored by operators, so that excessive waste on human resources is avoided.
Several embodiments of the present invention will be described in detail below with reference to the accompanying drawings in order to better understand the aspects and effects of the present invention.
Please refer to fig. 1, which is a flowchart illustrating a first embodiment of a method for adding neighbors according to the present invention, as shown in fig. 1, the method includes:
s101, UE in a first cell reports a measurement report to a service base station of the UE, wherein the measurement report carries identification information of a second cell obtained by UE measurement of different systems, and the first cell and the second cell are cells of different systems. For example, the first cell is an LTE cell and the second cell is a GSM or UMTS cell.
In addition, it should be noted that the second cell in this embodiment is a cell for which no neighboring cell relationship is configured with the base station. After receiving the measurement report reported by the UE, the base station learns, according to the second cell identifier in the measurement report, that the second cell is not configured as the neighboring cell of the base station, and needs to add the second cell as the neighboring cell. Before adding the neighbor cell, the base station performs the following steps to obtain the MSCID of the second cell.
S102, the base station sends a query message to the centralized control equipment, wherein the query message carries the identifier of the second cell and is used for querying the MSCID of the second cell.
The base station is located in the control range of the centralized control device, the centralized control device is used for coordinating the operation of a plurality of base stations in the control range of the centralized control device, and the configuration data of the cell controlled by each base station in the control range is stored, and the configuration data comprises the MSCID of the corresponding cell. For example, the configuration data exists in the form of a table that embodies the correspondence between the identity of each cell and the MSCID.
It should be noted that the identifier of the second cell carried in the query message may be identifier information of the second cell in a measurement report reported by the UE, or may be an identifier of the second cell obtained according to the identifier information of the second cell in the measurement report. That is, the identifier of the second cell carried by the query message may be the same as or different from the type of the identifier information reported by the UE in the measurement report. Meanwhile, the cell identifier in the configuration data stored in the centralized control device may be consistent with or inconsistent with the type of the identifier information reported by the UE in the measurement report. And when the cell identifiers are inconsistent, the base station receives the identifier information reported by the UE, needs to convert the identifier information into identifiers which are consistent with the identifier types of the cells stored in the centralized control equipment, and sends the identifiers to the centralized control equipment so as to inquire the corresponding MSCID.
And S103, after receiving the query message, the centralized control equipment queries the stored configuration data to obtain the MSCID corresponding to the identifier of the second cell carried in the query message.
And S104, the centralized control equipment sends the inquired MSCID to the base station.
After obtaining the MSCID of the second cell in the above manner, the base station adds the second cell as a neighboring cell (S105). For example, the identity of the second cell is added to the NRT or NCL of the base station. The MSCID may also be added to the NRT or NCL of the base station at the same time as the cell identity is added. Therefore, the MSCID corresponding to the second cell can be known in the subsequent CSFB, and thus the CSFB failure can be reduced.
It should be noted that step S105 may also occur before step S102, that is, the second cell may be added as a neighboring cell, and then the MSCID of the second cell is obtained. The embodiment of the present invention does not limit this.
For example, the UE is located in a region where the first cell and the second cell overlap. When the UE knows that the signal strength of the second cell is better than that of the first cell through inter-system measurement, it may report a measurement report to the serving base station. The measurement report carries identification information of the second cell to inform the serving base station that the UE can be handed over to the second cell. After receiving the measurement report reported by the UE, the base station finds that the second cell is not a neighboring cell, e.g., not in its NRT. At this time, the base station may add the second cell as a neighboring cell. In order to ensure the normal operation of the CSFB after the second cell is added as the neighboring cell, the base station obtains the MSCID of the second cell by sending a query message to the centralized control device, so that when the UE needs to initiate a voice service, the corresponding MSC can be known, and the CSFB is ensured to be performed smoothly.
It can be seen that, an embodiment of the present invention provides a method for adding a neighboring cell, where an execution main body of the method is a base station, please refer to fig. 2, which is a flowchart of a second embodiment of the method for adding a neighboring cell of the present invention, and the method may include the following steps:
s201, a base station receives a measurement report reported by UE in a first cell controlled by the base station, wherein the measurement report carries identification information of a second cell, and the first cell and the second cell are different system cells.
It should be noted that, the embodiment of the present invention does not limit the content of the identification information, and as long as the information for identifying the second cell is obtained through UE measurement, the information may be used as the identification information. The configuration data of each cell stored by the centralized control equipment comprises the identification of the cell and the MSCID which correspond to each other. The cell identifier may be the same as or different from the type of identifier information reported by the UE in the measurement report. And when the cell identifiers are inconsistent, the base station receives the identifier information reported by the UE, needs to convert the identifier information into identifiers which are consistent with the identifier types of the cells stored in the centralized control equipment, and sends the identifiers to the centralized control equipment so as to inquire the corresponding MSCID.
Taking the first cell as an LTE cell, and the second cell as a first-stage Radio Transmission technology (1X Radio Transmission technology, abbreviated as 1XRTT) cell of a Code Division Multiple Access (CDMA) technology, the cell identifier of the 1XRTT cell may be a base station identifier BaseId, a network identifier (Net ID, abbreviated as NID), and a System identifier (System ID, abbreviated as SID).
S202, the base station sends a query message to the centralized control equipment, wherein the query message is used for querying the MSCID of the second cell and carries the identifier of the second cell.
The centralized control device is a server or a network device that stores the identifier of the second cell and parameters (e.g., MSCID) related to the CSFB service, and the centralized control device may obtain the parameters related to the CSFB service from the identifier of the cell. Alternatively, the centralized control device may store the identities of all cells within its control range and parameters related to the CSFB service. Taking the second cell as the 1XRTT cell as an example, if the base station needs to acquire parameters related to the CSFB service, such as the MSCID, of the 1XRTT cell, the base station sends a query message to the centralized control device, where the query message includes an identifier of the 1XRTT cell, such as BaseID, SID, NID.
Optionally, the centralized control device may be an MME or a network management device. Further, if the centralized control device is an MME, the query message may be a Radio Access Network information management (RIM) message. Wherein the RIM message carries the cell identity of the second cell. Using RIM messages as query messages may avoid adding new interface messages in the definition of the existing protocol.
Optionally, the base station may send the query message to the centralized control device through a private interface.
S203, the base station receives the MSCID of the second cell returned by the centralized control equipment according to the identifier of the second cell.
The base station receives the MSCID of the second cell related to the CSFB service for use when the subsequent UE initiates the CSFB service flow.
And S204, the base station adds the second cell as a neighboring cell.
Wherein the adding, by the base station, the second cell as a neighboring cell includes: and adding the identifier of the second cell into a neighbor cell relation table NRT or a neighbor cell list NCL of the base station.
Further, the above method may further include: adding the MSCID of the second cell to the NRT or NCL.
Optionally, in step S201, after the base station receives the measurement report reported by the UE camped on the first cell, the base station may check whether parameters related to the CSFB of the second cell are already saved, and if so, steps S202 to S203 may not be performed.
Optionally, the parameter MSCID obtained by the method for adding a neighboring cell provided by the present invention may also be used in other business processes in the art.
Optionally, the method for adding a neighboring cell provided by the present invention may also be used to obtain parameters related to the second cell and other service flows, such as: other parameters not stored by the current base station.
In the method for adding a neighboring cell provided in this embodiment, in order to ensure that CSFB after adding a second cell as a neighboring cell can be performed normally in a process of adding a neighboring cell, a base station sends a query message to a centralized control device to obtain an MSCID of the second cell, so that when a UE needs to initiate a voice service, a corresponding MSC can be known, and smooth CSFB is ensured.
In addition, an embodiment of the present invention further provides a neighboring cell adding method, where an execution main body of the method is a centralized control device, please refer to fig. 3, which is a flowchart of a third embodiment of the neighboring cell adding method of the present invention, and the method may include the following steps:
s301, a centralized control device receives an inquiry message sent by a first base station, wherein the inquiry message carries a cell identifier, the centralized control device is used for coordinating the operation of a plurality of base stations in the control range of the centralized control device, configuration data of a cell controlled by each base station in the control range are stored, and the configuration data of each cell comprises an MSCID of a corresponding cell. In addition, the first base station is any base station within the control range of the centralized control device.
The centralized control device may be a server or a network device that stores configuration data of cells controlled by each base station within its control range. Optionally, the centralized control device may be an MME or a network management device.
S302, the centralized control equipment inquires the stored configuration data to obtain the MSCID corresponding to the cell identifier.
If the centralized control device is an MME, the query message may be an RIM message, which carries a cell identifier and is used to query an MSCID corresponding to the cell identifier.
S303, the centralized control equipment sends the inquired MSCID to the first base station.
If the centralized control equipment is an MME, the MME may carry the queried MSCID through an RIM message.
In the method for adding a neighboring cell provided in this embodiment, in order to ensure that CSFB after adding a second cell as a neighboring cell can be performed normally in a process of adding a neighboring cell, a base station sends a query message to a centralized control device to obtain an MSCID of the second cell, so that when a UE needs to initiate a voice service, a corresponding MSC can be known, and smooth CSFB is ensured.

In the embodiment of the invention, in the process of adding the different system cell as the adjacent cell, the MSCID of the different system cell is inquired from the centralized control equipment to obtain and store the MSCID for the subsequent CSFB process, thereby ensuring the CSFB to be smoothly carried out.
