Description

The present invention relates to the field of communications, and in particular, to a method for processing link and configuration errors, a user equipment, and a base station. Background Art In an LTE-A system, when a user equipment detects some serious error and cannot communicate again, the user equipment needs to initiate a connection re-establishment process. Through the re-establishment process, the connection between the user equipment and the network side is restored, the security function is reactivated, and the primary cell can also be configured. During the re-establishment process, there is a phase in the communication between the user equipment and the network side that can only send signaling that is not protected by the security mechanism. After the completion of the reconstruction process, only the signaling transmissions that are partially protected by the security mechanism are restored. The data transmission and a part of the signaling transmission protected by the security mechanism require other processes to be configured to be recovered.

In general, the reconstruction process is performed by the Radio Resource Control (RRC) layer. The user equipment must and only initiate the re-establishment process after the security function of the access layer is started. When the rebuild process is initiated, the rebuild process can be initiated when one of the following five conditions is met: (1) a radio link failure is detected; (2) a handover failure; (3) an E-UTRA (Evolved Universal Terrestrial Radio) (Access) fails; (4) The integrity detection failure indication is obtained from the bottom layer; (5) The RRC connection reconfiguration fails.

In the initial stage of the reconstruction process, all radio bearers (except the No. 0 signaling radio bearer) are suspended. At this time, the user equipment and the network can only transmit using the No. 0 signaling radio bearer without security protection. Signaling), the basic underlying configuration is set to the default configuration, and the associated enhanced configuration is released. After completing these operations, cell selection is performed, and a cell with a better signal is selected as the target of connection reconstruction. If a cell is selected within a specified time, the user equipment is ready to send a reestablishment request. After the re-establishment request is sent, if the re-establishment message sent by the base station is received within the specified time, the radio bearer No. 1 radio is recovered (at this time, part of the signaling transmission protected by the security mechanism is restored), The reactivation of the security mechanism is then carried out. Finally, a rebuild complete message is generated, the relevant operations are completed, and the underlying transport is submitted. At this point, the user equipment side reconstruction process ends. On the other hand, in the current LTE-A system, a macro cell (Macro Cell) is mainly deployed. In the future, as the traffic volume increases, in order to perform system load offloading or extended coverage, it may be necessary to continue to deploy small cells (for example, a micro cell Micro Cell or a Pico Cell, a femto cell Femto Cell, a remote radio head RRH, etc.). The coverage area of small cells is relatively small, but the number is relatively large.

However, the inventors have found that if the deployment of small cells is simply increased, the number of handovers can be significantly increased when the terminal moves in a place where dense small cells are deployed. This will increase the control signaling burden. Especially for some high-speed users, the dropped call rate will increase significantly, which will seriously affect the user experience.

It should be noted that the above description of the technical background is only for the purpose of facilitating a clear and complete description of the technical solutions of the present invention, and is convenient for understanding by those skilled in the art.

detailed description

The foregoing and other features of the invention will be apparent from the The specific embodiments of the present invention are disclosed in the specification and the drawings, which are illustrated in the embodiments of the invention The invention includes all modifications, variations and equivalents falling within the scope of the appended claims.

In the standard organization, in order to solve the problems existing in the coexistence of macro cells and small cells, a dual connectivity (Dual Connectivity) structure is proposed. In a dual connectivity architecture, a user equipment (or terminal) can establish two or more connectivity simultaneously with the network side. Typically, one path is between the user equipment and the macro cell base station, and the other is between the user equipment and the small cell base station, which may be referred to herein as a first path (e.g., a macro path) and a second path (e.g., a small path).

In general, the macro channel has more powerful functions than the small path, and can have more control functions. For example, the radio resource control function of the control plane may exist only in the macro path, or the radio resource control function in the macro path has a part of the radio resource control function of the small path in addition to controlling the macro path; or carrying more channels, for example The macro path can carry a broadcast channel, a paging channel, etc.; or carry more types of radio bearers. For example, the macro path can carry a signal radio bearer and a data radio bearer. On the small path, only the data radio bearer can be carried.

It should be noted that the first path of the present invention is not limited to being between the user equipment and the macro cell base station, and the second path is not limited to being between the user equipment and the small cell base station. For example, the first path may also exist between the user equipment and the small cell base station, and the second path may exist between the user equipment and the macro cell base station; in this scenario, the first between the user equipment and the small cell base station The function of the path may be stronger than the function of the second path between the user equipment and the macro cell base station. The present invention is not limited thereto, and the present invention will be described in detail below by taking the first path between the user equipment and the macro cell base station and the second path between the user equipment and the small cell base station as an example. At the same time, there may be more than two paths between the user equipment and the network, such as three or four. Among these paths, one path is the first path and the remaining paths are the second path. The invention is equally applicable to the case of two or more channels.

Within each path, there will be multiple layers (eg, physical layer, MAC layer, RLC layer, etc.) to complete the functions of the control plane (mainly related to the generation and transmission of air interface control signaling) and the functions of the user plane (mainly involved) Empty mouth Transmission of household data). In order to realize the dual connectivity structure, the protocol stack structure of the air interface has various options. The following is an example of a protocol stack structure with a separate Packet Data Converge Protocol (PDCP) layer in the two paths.

Control Plane (CP): For the uplink of the air interface, the transmitter is at the user equipment. FIG. 1 is a schematic structural diagram of a control plane protocol stack on the uplink user equipment side, showing a case of being separated from the PDCP layer.

As shown in Figure 1, there are distributed PDCP layer, RLC layer, MAC layer and physical layer PHY (Physical Layer) in both paths. However, there is a centralized RRC layer in the user equipment, which is used to control two. The other layers in the path.

For the downlink of the air interface, the transmitting end is at the base station. Fig. 2 is a schematic diagram showing the structure of a control plane protocol stack on the downlink base station side, showing the case of being separated from the PDCP layer. As shown in Fig. 2, there are distributed PDCP layer, RLC layer, MAC layer and PHY layer in both paths in the macro base station and the small base station. However, there is a centralized RRC layer in the macro base station for controlling the other layers in the two paths.

User plane (UP): For the uplink of the air interface, the transmitting end is at the user equipment. FIG. 3 is a schematic structural diagram of a user plane protocol stack on the uplink user equipment side, showing a case of being separated from the PDCP layer. As shown in Figure 3, there are distributed PDCP layers, RLC layers, MAC layers, and PHY layers in both paths.

For the downlink of the air interface, the transmitting end is at the base station. Figure 4 is a block diagram showing the structure of the user plane protocol stack on the downlink base station side, showing the case of being separated from the PDCP layer. As shown in FIG. 4, there are distributed PDCP layers, RLC layers, MAC layers, and PHY layers in both paths in the macro base station and the small base station.

If a dual-channel structure is adopted, the reliability of the handover can be improved and the traffic of the user equipment can be increased at the same time. However, the two-pass structure has new problems. For example, in the existing protocol, if the integrity check of the PDCP layer fails, the user equipment performs connection reestablishment. In the dual-path structure, each PDCP layer is in each path, and the failure detection of each path will cause the connection reconstruction of the user equipment. In fact, if the second path is relatively simple, even if the integrity detection fails, the second path needs to stop communication, but the first path is still normal, and the user equipment can still communicate through the first path. Therefore, if only the integrity detection failure of the second path occurs, the user's connection reconstruction is unnecessary and needs to be avoided. In addition, for all dual-path structures, the same problem exists with the relationship between link configuration failure and connection re-establishment. These problems are caused by the special structure of the two-channel. Example 1 The embodiment of the invention provides a method for processing link and configuration errors, which is applied to a communication system in which a dual path exists between a user equipment and a network side. This embodiment will be described from the user equipment side. Wherein, the dual path includes a first path and a second path, and the function of the second path is weaker than the function of the first path.

FIG. 5 is a schematic flowchart of a processing method according to an embodiment of the present invention. As shown in FIG. 5, the method includes: Step 501: When a configuration of a second path fails, or when a packet data convergence protocol layer in a second path is received When the integrity check fails, the user equipment does not initiate a connection re-establishment process.

In this embodiment, if there is a dual path between the user equipment and the network side, when the configuration of the second path fails, the user equipment does not initiate a connection re-establishment process. Specifically, the configuration failure of the second path may include a resource configuration failure or the like.

Or, if there is a dual path between the user equipment and the network side, and there is a distributed in both paths

The PDCP layer, when receiving the integrity detection failure indication of the PDCP layer in the second path, does not initiate the connection re-establishment process.

For example, in the structure shown in Fig. 1 or Fig. 3 and the like, there are distributed PDCP layers in both the first path and the second path. Then, when the user equipment receives the integrity detection failure indication of the PDCP layer in the second path, the connection re-establishment process is not initiated.

Therefore, by enhancing the connection establishment trigger mechanism, it is ensured that the communication between the user equipment and the network is not interrupted unnecessarily, the reliability of the communication is improved, and the user experience is ensured.

In this embodiment, in the case that the user equipment in which the link and the configuration error occur does not initiate connection reestablishment, the second path may be further processed.

FIG. 6 is another flowchart of the processing method of the embodiment of the present invention. As shown in FIG. 6, the processing method includes: Step 601, when the configuration of the second path fails, or when the packet data convergence in the second path is received When the integrity check of the protocol layer fails, the user equipment does not initiate the connection re-establishment process.

Step 602: The user equipment releases the second path.

Step 603: The user equipment notifies the base station that the second path has been released through the uplink of the first path. In a specific implementation, the user equipment may release the second path by itself and then notify the base station that the second path has been released. The process of releasing the second path (e.g., the small path) may include: stopping all of the timers in the second path, and releasing all of the radio resources corresponding to the second path. The method may include releasing a MAC entity in the second path, an RLC entity, a PDCP entity, and the like corresponding to all established radio bearers.

FIG. 7 is another flowchart of a processing method according to an embodiment of the present invention. As shown in FIG. 7, the processing method includes: Step 701: When the configuration of the second path fails, or when the integrity detection failure indication of the packet data convergence protocol layer in the second path is received, the user equipment does not initiate a connection re-establishment process.

Step 702: The user equipment reports an error of the second path to the base station by using the uplink of the first path. Step 703: The user equipment receives a release message sent by the base station by using the downlink of the first path. Step 704: The user equipment is released according to the The message releases the second path.

In a specific implementation, the user equipment may first report to the base station that an error has occurred in the second path through the uplink of the first path. Then, the base station can notify the user equipment to release the second path through the downlink of the first path. After receiving the message sent by the base station to release the second path, the user equipment releases the second path. The process of releasing the second path (e.g., the small path) may include: stopping all of the timers in the second path, and releasing all of the radio resources corresponding to the second path. The method may include releasing a MAC entity in the second path, an RLC entity, a PDCP entity, and the like corresponding to all established radio bearers.

As shown in FIG. 8, the processing method includes: Step 801, when the configuration of the second path fails, or when the packet data convergence in the second path is received When the integrity check of the protocol layer fails, the user equipment does not initiate the connection re-establishment process.

Step 802: The user equipment requests the base station to reestablish the second path by using the uplink of the first path. Step 803: The user equipment receives the re-establishment message sent by the base station by using the downlink of the first path. Step 804, the user equipment reconstructs according to the reestablishment message. The second path.

In a specific implementation, the user equipment may request to reconstruct the second path through the uplink of the first path, that is, implicitly report to the base station that the second path has an error. Then, the base station can notify the user equipment to reestablish the second path through the downlink of the first path. The user equipment reconstructs the second path based on the received message.

Specifically, the process of reestablishing the second path may include: the user equipment suspends all radio bearers belonging to the second path, configures the bottom layer of the second path as a default configuration, and releases other configurations; and then the user equipment selects a more suitable one. The cell, reestablishing the second path between the user equipment and the selected cell, including restoring the suspended radio bearer. During the reconstruction of the entire second path, the user equipment can always communicate with the network side through the first path.

Thus, by releasing or rebuilding the second path, it is possible to ensure that the user equipment recovers from the link and configuration errors. In addition, by reconstructing the second path, on the basis of ensuring continuity of communication between the user equipment and the network, the second path can be restored, thereby improving the communication speed of the user equipment.
