Description

Communication processing method and device

Technical Field

The present invention relates to the field of communications, and in particular, to a communication processing method and apparatus.

Background

The rapid development of mobile internet, internet of things, and other business applications has become a major driving force for the development of fifth generation mobile communication technology (5G). They have an urgent need for 5G with access rates comparable to that of optical fibers, connectivity capabilities of billions of devices, a perfect real-time experience, and wireless broadband access capabilities anywhere and anytime. In addition, important indexes such as energy consumption efficiency, spectral efficiency and peak rate also need to be comprehensively considered in the design of the 5G system. China established the IMT-2020(5G) push group in 2013 to drive the development of 5G technology. It is expected that a 5G vision, critical capacity requirements and spectrum planning will develop in 2015, according to the international global situation, after which 5G standardization work will be initiated and start to be commercially available after 2020. In terms of international standards, technical standards of a Long-Term Evolution advanced (Long-Term Evolution) system are mainly formulated by the 3GPP international standardization organization. It was preliminarily believed that 5G-oriented standard research work was initiated in 3rd generation partnership project (3 GPP) R14 (expected in 2016).

In future mobile networks, the traffic demand will increase continuously, and the number and types of terminals will increase explosively. As one of important scenes and technical means of 5G, Ultra Dense Networks (UDN) are receiving more and more attention. When the existing LTE-a technology is applied to an ultra-dense network, interference between Common Reference Signals (CRS) of cells becomes more serious as the number of cells increases. To avoid this interference, the UDN often needs to perform inter-cell coordination switching, i.e. turning off some cell base stations for a certain period of time to reduce interference, and turning off another cell base station for another period of time. In order to coordinate and reduce the interference of each cell, the ideal backhaul link can be used to exchange the traffic information in real time, and the switch of each cell can be controlled centrally according to the traffic information. However, the ideal backhaul link greatly increases the deployment cost of the backhaul network, and it is difficult to fully implement the ideal backhaul in all coverage scenarios in actual network deployment. In order to coordinate interference between cells under the condition that a backhaul link is not ideal, an interference coordination mode (hereinafter, referred to as a pattern switching mode) in which cell switching is performed according to a pattern is often used, that is, each cell switches cell signals according to a certain pattern, so as to reduce interference between cells. The specific switching patterns may be uniformly distributed by the central node, or may be generated by each cell and its neighboring cells through negotiation according to the detected interference condition. Each unit time period for cell switching in a pattern may be from one 1 millisecond (ms) subframe to multiple 10ms radio frames, and the control duration of the entire pattern (i.e., the entire switching pattern period) depends on the actual length of the employed switching pattern, and may be from several ms to tens, hundreds, thousands of ms, or even longer. In this way, the interaction of the related control information among the cells can be performed according to the actual delay condition of the backhaul link, and an aperiodic or periodic switching control pattern with a corresponding length is generated. The granularity of unit time for performing cell switching once is referred to as a unit time period of pattern switching, and the length of the unit time period may be one or more subframes. For simplicity, in the following description, a unit period in which switching is performed in a pattern of one subframe is referred to as an ON subframe, and a subframe in an OFF state is referred to as an OFF subframe.

Although the pattern switching mode can effectively perform interference coordination under the condition that the backhaul link is not ideal, the peak rate of the user is limited to a certain extent. This is because the cell is in an OFF (OFF) state for a portion of the subframe segment, which the user cannot use for data transmission. To overcome this drawback, a multi-connection data transfer scheme may be adopted, i.e. a user establishes multiple connections with multiple neighboring cell base stations at the same time, and uses different connections for data transmission at different switch unit times. Therefore, the user can utilize all the sub-frames to carry out data transmission, and the peak rate of transmission is greatly improved. Meanwhile, because a plurality of connections exist simultaneously, the reliability of user access is obviously improved. The multi-connection mechanism may also serve as a potential solution for highly reliable communication. Moreover, because each cell of the UDN uses a channel with the same frequency point, the multi-connection communication mode can be realized only by using one set of wireless equipment without increasing the cost of the user terminal, which is completely different from the different-frequency dual-connection scheme discussed by 3 GPP. It is noted that the ON subframe configuration used by each connection of the multi-connection user may be different from the ON subframe configuration in the switching pattern of the peer base station of each connection, and the former may be only a subset of the latter. The ON subframes used by a connection between a connected base station and a multi-connection user are referred to as ON subframes belonging to a connection, and the distribution of the ON subframes is also referred to as the subframe configuration of the connection provided by the base station.

However, as the user moves, some connected base stations may issue handover requests or commands. However, the overall service quality is reduced by adopting the switching process in the related technology, and how to optimize the whole switching process in the pattern switch mode and minimize the influence caused by connection switching is a problem which needs to be studied.

Aiming at the problem that the overall service quality is reduced when a base station is switched in the related technology, an effective solution is not provided at present.

Through the steps, when the first source base station of the user equipment needs to be switched, the subframes of the first source base station communicating with the user equipment can be distributed to other source base stations connected with the user equipment and a target base station, so that more subframes for communicating can be arranged between other source base stations and the user equipment, the influence of base station switching on the service is reduced, the problem that the overall service quality is reduced when the base station is switched in the related technology is solved, and the effect of completing the base station switching under the condition of not influencing the service quality is further achieved.

step S204, the second source base station communicates with the user equipment by using the subframe allocated by the first source base station.

Through the steps, when the first source base station of the user equipment needs to be switched, the second source base station connected with the user equipment receives the subframes distributed by the first source base station and communicates with the user equipment by using the distributed subframes, so that more subframes for communicating can be arranged between the second source base station and the user equipment, the influence of base station switching on services is reduced, the problem that the overall service quality is reduced when the base station is switched in the related technology is solved, and the effect of completing base station switching under the condition of not influencing the service quality is further achieved.

Fig. 3 is a flowchart of a third communication processing method according to an embodiment of the present invention, and as shown in fig. 3, the flowchart includes the following steps:

step S302, a target base station receives a subframe which is distributed by a first source base station of user equipment and is used for communication between the first source base station and the user equipment;

step S304, the target base station communicates with the user equipment by using the subframe allocated by the first source base station.

In the above step, when it is determined that the ue needs to switch the first source base station, the first source base station allocates the subframe in which the first source base station communicates with the ue to the target base station, so that the target base station can communicate with the ue using the allocated subframe, which solves the problem in the related art that the overall service quality is reduced when the ue switches the base station, and achieves the effect of completing the base station switch without affecting the service quality.

In order to optimize the user experience in the whole switching process in the pattern switch mode and reduce the influence caused by connection switching as much as possible, the embodiment of the invention also provides a cooperation mechanism for multi-connection communication in the switching process in the pattern switch mode. The cooperation mechanism occurs before the source base station sends the handover command, and is used for allocating the part of the ON subframes originally belonging to the connection to be handed over to other connections of one or more multi-connection users.

Fig. 17 is a schematic diagram of a pattern switch scenario according to an embodiment of the present invention, in which an Ultra Dense Network (UDN) scenario applying a pattern switch operation mode is described. With the development of the future 5G wireless network and the popularization of the wireless broadband application, the scenes of ultra-dense networks (UDNs) will be more and more. The macro base station coverage can provide a wide range of wireless link support, but the quality of the link is influenced to a certain extent due to a long transmission distance; each small base station provides a better wireless link for the terminal for enhancing the capacity of the network. However, with the densification of small cell coverage, the distribution of small base stations is more encrypted and disordered, the interference between small cells becomes very complex, more edge users are generated, and the overall throughput of the entire UDN network is severely limited. In order to coordinate interference between cells under the condition that a backhaul link is not ideal, an interference coordination mode (hereinafter, referred to as a pattern switching mode) in which cell switching is performed according to a pattern is often used, that is, each cell switches cell signals according to a certain pattern, so as to reduce interference between cells. The right side of the figure shows an example of a switching pattern for each small cell. The switching patterns of different small cells are different, but they are synchronized in time and all consist of multiple unit time periods. Each cell may determine its own on-off state per unit time period according to a pattern. The specific switching patterns may be uniformly distributed by the central node, or may be generated by each cell and its neighboring cells through negotiation according to the detected interference condition. The unit time period for cell switching in the pattern may be from one 1 millisecond (ms) subframe to a plurality of 10ms radio frames, and the control duration of the entire pattern (i.e., the entire switching pattern period) depends on the actual length of the switching pattern, and may be from several ms to several tens, hundreds, thousands of ms, or even longer. In this way, the interaction of the related control information among the cells can be performed according to the actual delay condition of the backhaul link, and generate a non-periodic or periodic switching control pattern with a corresponding length.

Fig. 18 is a diagram of multi-connection communication according to an embodiment of the present invention, in which a diagram of multi-connection communication performed by a user is described. Although the pattern switching mode can effectively perform interference coordination under the condition that the backhaul link is not ideal, the peak rate of the user is limited to a certain extent. This is because each cell is in an OFF (OFF) state for a portion of the subframe segment, which the user cannot use for data transmission. To overcome this drawback, a multi-connection data transmission scheme may be adopted, in which a user establishes multiple connections with multiple neighboring cell base stations at the same time, and uses different connections for data transmission at different switch unit times. In fig. 18, user a establishes multiple connections with base stations 2, 3, 4 simultaneously. Since the base stations 2, 3, 4 are switched on and off differently during the same time period, the user a can use different connections for data transmission at different times. Therefore, the user can carry out data transmission in all subframes, and the peak rate of single-user transmission is greatly improved. In fig. 18, user a communicates with base station 2 in subframes #1, #3, # 5; communicating with base station 3 in subframe # 2; and communicating with the base station 4 in subframes #4 and # 6. In addition, because each cell of the UDN uses channels with the same frequency point, the multi-connection time division communication mode can be realized only by using one set of wireless equipment, and the cost of a user terminal is not increased. It is noted that the ON subframe configuration used by each connection of the multi-connection user may be different from the ON subframe configuration in the switching pattern of the peer base station of each connection, and the former may be only a subset of the latter. In the description of this patent, the ON subframes used by a connection between a connected base station and a multi-connected user are referred to as ON subframes belonging to a connection, and the distribution thereof is also referred to as the subframe configuration of the connection provided by the base station.

Fig. 19 is a schematic diagram of an LTE handover procedure according to an embodiment of the present invention. As shown in fig. 19, the process includes the following steps:

in step S1902, a user (i.e., the user equipment and the user terminal) and a source base station first perform measurement and related interaction, and decide to perform cell handover.

Step S1904, the source base station selects a target base station, and performs handover request interaction with the selected base station.

In step S1906, the source base station sends a handover command (RRC connection reconfiguration message) to start an actual user handover procedure, and sends control information and data packets related to the user to the target base station.

In step S1908, the user immediately hangs up the connection of the source base station after receiving the handover command.

Step S1910, the user starts synchronizing with the target base station.

Step S1912, the user sends RRC connection reconfiguration complete message to report completion of handover

Step S1914, the user starts the processing procedure after the handover, including the service flow routing handover procedure of the core network and the resource release of the source base station.

Fig. 20 is a schematic diagram of a first multi-connection handover procedure according to an embodiment of the present invention. As shown in fig. 20, the cooperation mechanism for multi-connection communication in the handover process provided in this embodiment occurs before the source base station sends the handover command, and is used to allocate a part of ON subframes in the subframe configuration of the source base station to be handed over to other connections of one or more multi-connection users. Therefore, the switching mechanism of the multi-connection communication in the pattern switch mode provided by this embodiment is implemented as follows:

step S2002, a certain multi-connection user and a certain source base station perform measurement and related interaction, and decide to perform cell handover on a certain connection.

Step S2004, the source base station and the adjacent base station carry out switching request interaction, and the selection of the target base station and other switching preprocessing processes are completed.

Step S2006, the source base station and other connected base stations of the multi-connection user perform multi-connection handover cooperative interaction: and based ON the switching patterns of all connected base stations, the source base station allocates part of ON subframes in the subframe configuration belonging to the connection to be switched to other connections of one or more multi-connection users, so that the other connections can use the subframes to communicate with the multi-connection users after the switching is started. In addition, the source base station interacts with the switching target base station and informs the switching target base station of the subframe configuration information which can be used by the newly-built connection after the switching is started.

Step S2008, the source base station and the multi-connection user to be switched perform a subframe configuration update notification process to notify the user of updated subframe configuration information of each connection, where the subframe configuration information includes a subframe configuration of a new connection of the target base station and updated subframe configurations of other connections. In fig. 20, the subframe configuration update notification procedure includes a "subframe configuration update notification" message sent by the source base station to the user and a "subframe configuration update confirmation" message sent by the user.

Step S2010, the source base station and the target base station complete a subsequent connection switching process based on the updated subframe configuration information.

Fig. 21 is a schematic diagram of a second multi-connection handover procedure according to an embodiment of the present invention. The whole process is basically the same as that in fig. 20, except that the subframe configuration update information sent to the user is included in the original handover command message (i.e. RRC connection reconfiguration message).

Fig. 22 is a schematic diagram of a multi-connection handover collaboration flow according to an embodiment of the invention. As shown in fig. 22, the specific process of the multi-connection switching cooperative interaction in fig. 20 and 21 is implemented as follows:

in step S2202, the source base station transmits a "multi-connection user subframe configuration update request" message to one or more connected base stations. The message contains position indication information of the ON subframes allocated by the source base station to the other respective connections. These allocated ON subframes are all the ON subframes originally belonging to the connection to be switched.

Step S2204, each connected base station that receives the above message sends a "multi-connection user subframe configuration update response" message. The message includes position indication information of the allocated ON subframe accepted by each connected base station.

Step S2206, the source base station determines the ON subframe configuration of the new connection of the target base station according to the received response, and includes the relevant information in the "multi-connection user subframe configuration notification" message and sends the notification message to the target base station.

Step S2208, the target base station sends a "multi-connection user subframe configuration response" message to confirm the ON subframe configuration used by the newly-established connection after the handover.

For example, when the connection of user a and base station 2 of fig. 18 is switched to base station 1, base station 2 may reconfigure the ON subframes (including subframes #1, #3, #5) originally belonging to his connection with user a. For example: by combining with the switching pattern information of fig. 17, the base station 2 can allocate the #1 subframe to the connection of the base station 3 and the user a, allocate the #3 subframe to the connection of the base station 4 and the user a, and allocate the #5 subframe to the connection of the base station 1 and the user a. In this way, in the handover process, the connected base stations 3 and 4 can use 2 more subframes to serve the user a, so that the change of the user-perceived traffic rate in the whole handover process is small.

In addition, the source base station may also update the service information of each connection by using the above messages, and allocate the service carried by the switched connection to other connections of the multi-connection user, that is, other connected base stations and each connection of the user. In this case, each message further includes parameters and information related to service update. Specifically, the "multi-connection user subframe configuration update request" message may include a service update parameter allocated to each other connection by the source base station; the "multi-connection user subframe configuration update response" message may include service update parameters accepted by each connected base station; the "multi-connection user subframe configuration notification" message may include service parameters that should be supported after the target base station is switched; the "multi-connection user subframe configuration response" message may contain confirmation information of the target base station on the switched service parameters. The service related update information may also be included in the interactive messages of other handover procedures or be delivered in separate messages.

The integrated modules of the present invention may also be stored in a computer-readable storage medium if they are implemented in the form of software functional modules and sold or used as separate products. Based on such understanding, the technical solutions of the embodiments of the present invention may be embodied in the form of a software product, which is stored in a storage medium and includes instructions for causing a computer device (which may be a personal computer, a server, or a network device) to execute all or part of the method of the present invention.

Correspondingly, the embodiment of the invention also provides a computer storage medium, wherein a computer program is stored, and the computer program is used for executing the implementation method provided by the invention.

Through the embodiments of the invention, the user experience in the whole switching process can be optimized in the pattern switch mode, and the influence caused by connection switching is reduced as much as possible. By allocating the ON subframes used by the connection in the switching state to other connections, the other connections can have more ON subframes to communicate with the user. In addition, the multi-connection subframe configuration information adopted by the interaction of the source base station, the target base station and the multi-connection user in the switching process enables the multi-connection user to smoothly interact with the target base station on one hand, and the switching process is completed; on the other hand, the multi-connection user can successfully use other connections for communication in the switching process of a certain connection, and the receiving of the service data of the user in the switching process is ensured. Finally, through the updating of the service information of each connection, the service requirement borne by the source base station connection can be transferred to other connections, and the overall service quality of the user is ensured.
