Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a system message sending method and RAN equipment.
Background
With the development of communication technology, in order to meet the requirement of expanding the functions of the communication system, the communication system may be compatible with other communication technologies (e.g., machine-type communication (MTC) technologies, etc.) on the basis of supporting the original mobile communication technology.
Accordingly, Radio Access Network (RAN) devices in a communication system need to have conventional mobile communication functions as well as other communication functions. Terminal devices supporting multiple communication technologies may coexist in a cell managed by the RAN device. Since the terminal device supporting any communication technology needs to configure resources in the same cell, the system message (e.g., System Information Block (SIB)) broadcasted by the RAN device is transmitted for the terminal device supporting each communication technology in the cell. However, the configuration of the system information (i.e., the scheduling period and the update period) of different communication technologies is generally different.
For example, in order to support a cost/coverage enhancement-oriented internet of things terminal, an enhanced machine-type communication (eMTC) technology is introduced into a communication system using a Long Term Evolution (LTE) technology. A cell managed by the RAN device needs to provide access services for a terminal device supporting an LTE technology (hereinafter, may be referred to as an LTE terminal device) and a terminal device supporting an eMTC technology (hereinafter, may be referred to as an eMTC terminal device) at the same time. Aiming at the eMTC technology, the communication system is additionally provided with a set of system information configuration mode which is configured independently from the traditional system information maintenance mode of the LTE technology. Generally, in order to ensure that the eMTC terminal device saves power, values of a scheduling period and an updating period of a system message of the eMTC technology are both large.
Based on the above situation, when the RAN device validates a new system message, both the LTE function and the eMTC function in the RAN device enable resource configuration of the system message, and the RAN device broadcasts the system message in the managed cell. If the RAN device takes effect of the new system message in the system message configuration mode of the first technology, the terminal device supporting the first technology may monitor the system message in the system message configuration mode of the first technology, but the terminal device supporting the second technology may not monitor the system message in the system message configuration mode of the second technology. This results in inconsistency between the time points at which the RAN apparatus side and the terminal apparatus side supporting the second technology take effect of the new system message, and the RAN apparatus and the terminal apparatus supporting the second technology use different resource configurations, which further affects the communication quality of the terminal apparatus supporting the second technology.

In order to better understand the technical solution provided in the embodiment of the present application, a system message configuration manner is described below by taking an LTE technology as an example.
After acquiring the updated resource configuration information and determining that the system message carrying the updated resource configuration information needs to be broadcasted, the RAN device sends a system message change notification and the system message according to a set update period of the system message of the LTE technology. For example, as shown in fig. 1, after acquiring updated resource configuration information, a base station determines an nth update period closest to the current time, and then starts to send a system message at the start time of the nth update period to notify a terminal device supporting LTE technology (hereinafter, referred to as LTE terminal device) in a cell to monitor a new system message in a next update period (i.e., an n +1 th update period). And the RAN takes effect on the configuration of the new system message at the starting moment of the (n + 1) th updating period, namely, performs resource configuration according to the resource configuration information and simultaneously sends the new system message.
Wherein, the sending mode of the system message is broadcast.
It should be further noted that each update period may include m scheduling periods, where m is a preset integer greater than 2. In the nth update period, the RAN device may transmit a system message change notification multiple times according to the scheduling period. During the (n + 1) th update period, the RAN device may transmit a new system message multiple times according to the scheduling period.
And after receiving the system message change notification in the nth update period, the LTE terminal device monitors a new system message in the (n + 1) th update period, and performs resource configuration according to the resource configuration information in the system message after monitoring the new system message. In this way, the RAN device and the LTE terminal device can validate the new system message at the same time, so that the same resource configuration can be used for communication.
In addition, it should be understood that the system message configuration manner of other communication technologies is similar to the system message configuration manner of the LTE technology, and is not described in detail in this embodiment. The only difference is that the size of the update period is different and the number of scheduling periods contained in each update period is different.
In order to more clearly describe the technical solutions of the embodiments of the present application, the following describes the solutions provided in the embodiments of the present application in detail with reference to the accompanying drawings.
Fig. 2 is a schematic diagram illustrating an architecture of a communication system to which the system message sending method provided in the embodiment of the present application is applied, where the communication system supports multiple communication technologies. As shown in fig. 2, the communication system includes a RAN apparatus 201 and a terminal apparatus 202.
The RAN device 201 is responsible for providing a Service related to radio access for the terminal device 202, and implements functions such as a radio physical layer function, resource scheduling and radio resource management, Quality of Service (QoS) management, radio access control, and mobility management. Since the communication system supports multiple communication technologies, accordingly, the RAN device can also support multiple communication technologies.
Alternatively, the RAN device may set a supported communication technology in addition to the basic mobile communication technology. For example, the RAN device may set that the RAN device currently supports or does not support eMTC technology by turning on or off some eMTC function.
The terminal device 202 is a device that accesses a network through the RAN device 201. Terminal devices 202 may be divided into various types depending on the communication technology supported. For example, as shown in fig. 2, the communication system includes a terminal device 202 supporting a first communication technology and a terminal device 202 supporting a second communication technology.
In the communication system, the RAN device 201 and each terminal device 202 are connected by a Uu interface, thereby realizing communication between the terminal device 202 and the RAN device 201.
The embodiment of the application provides a system message sending method. The method may be applied to a communication system as shown in fig. 2. Referring to fig. 3, the specific process of the method includes:
s301: the RAN device obtains the updated resource configuration information.
Optionally, the RAN device may obtain updated resource configuration information input by a user, or obtain the pre-stored resource configuration information.
Note that the resource configuration information is configuration information of radio resources common to all terminal devices (terminal devices supporting all communication technologies) in a cell managed by the RAN device, and examples of the configuration information include: resource allocation and scheduling of an Uplink Random Access Channel (RACH), a Physical Uplink Control Channel (PUCCH), a Physical Uplink Shared Channel (PUSCH), a Channel Sounding Reference Signal (SRS), and Uplink Channel power control information; and resource allocation of a Downlink Broadcast Control Channel (BCCH), a Physical Downlink Shared Channel (PDSCH), and a Paging Control Channel (PCCH).
S302: the RAN equipment determines a target time according to the update cycle of the system messages of the plurality of communication technologies when the RAN equipment determines that the plurality of communication technologies support currently, wherein the target time is a common starting time of the update cycle of the system messages of the plurality of communication technologies.
When the RAN device only supports one communication technology (generally, a mobile communication technology), the RAN device may process according to a conventional system message configuration manner, which may specifically refer to fig. 1, and is not described herein again.
Optionally, the plurality of communication technologies may include a mobile communication technology and at least one other communication technology (e.g., MTC technology). For example, when the communication system is a 4G communication system, the mobile communication technology may be an LTE technology, and the MTC technology may be an eMTC technology.
In addition, in order to ensure that the RAN device can reserve an update cycle to send a system message change notification before the target time for each communication technology, the target time further needs to satisfy the following conditions:
and the difference between the target time and the current time is greater than or equal to a set time threshold, and the value of the time threshold is the maximum update period in the update periods of the system messages of the multiple communication technologies.
Optionally, based on the above-mentioned limiting condition, the RAN device may determine a plurality of candidate time instants satisfying the above-mentioned condition. At this time, in order to improve the efficiency of resource configuration performed by the RAN device and the terminal device in the cell managed by the RAN device, the RAN device may select the candidate time closest to the current time as the target time.
Optionally, the RAN device may perform S302 by:
when the RAN equipment determines that the update cycle of the system message of the first communication technology is integral multiple of the update cycle of the system message of the second communication technology, determining the starting time of the update cycle of the first communication technology as the target time;
wherein the first communication technology is any one of the plurality of communication technologies, and the second communication technology is another one of the plurality of communication technologies other than the first communication technology.
By the above method, in the case that the update cycle of the system message of the first communication technology is an integer multiple of the update cycle of the system message of the second communication technology, the efficiency of the RAN device in determining the target time may be improved.
S303: and the RAN equipment determines the sending time of the system message change notification corresponding to each communication technology according to the update cycle of the system message of each communication technology and the target time.
The RAN device may perform S303 by:
and the RAN equipment subtracts the update period of the system message of each communication technology from the target time to obtain the sending time of the system message change notification corresponding to each communication technology.
S304: and the RAN equipment sends the system message change notification at the sending time of the system message change notification corresponding to each communication technology.
Optionally, when the system message configuration mode corresponding to any one of the communication technologies includes a scheduling period, the RAN device repeatedly transmits a plurality of system message change notifications according to the frequency of the scheduling period between the transmission time of the system message change notification and the target time.
S305: and the RAN equipment performs resource configuration at the target moment according to the resource configuration information and sends a system message, wherein the system message comprises the updated resource configuration information.
Wherein the RAN device transmits the system message in a broadcast manner.
In S305, the RAN device performs resource configuration at the target time, that is, the RAN device validates the system message. In addition, after the RAN device broadcasts the system message at the target time, the terminal device supporting each communication technology in the managed cell may receive the system message, and perform resource configuration according to the resource configuration information carried in the system message.
Optionally, the system message may be generated at any time after S301 and before S305, which is not limited in this embodiment of the application.
In the technical solution of the embodiment of the present application, when determining that a system message needs to be updated, a RAN device currently supporting multiple communication technologies first determines a common starting time of update cycles of the system messages of the multiple communication technologies, and takes effect and sends the system message when the time arrives. Since the RAN device sends the system message at the common starting time of the update cycle of the system messages of multiple communication technologies, by adopting the scheme, the RAN device and the terminal devices supporting multiple communication technologies in the cell managed by the RAN device can take effect of the new system message at the same time. In this way, the RAN device and the terminal device supporting various communication technologies can simultaneously adopt the same resource configuration for communication, thereby ensuring the communication quality of the terminal device supporting various communication technologies.
The following describes an example of system message transmission provided in the embodiment of the present application, by taking an example that RAN equipment in a communication system supports simultaneous support of an LTE technology and an eMTC technology. The system message configuration method of the LTE technology and the system message configuration method of the eMTC technology are respectively shown in fig. 4 (a) and (b).
Currently, in any system message configuration mode of communication technology, the definition of the update period is a default paging period (default paging cycle) and an update period coefficient (modification period coefficient). The default paging cycle may be represented by the number of radio frames (rf).
The system message update cycle of the LTE technology is as follows: t islte＝{rf32,rf64,rf128,rf256}*(2,4,8,16)；
The system message update cycle of the eMTC technology is as follows: t iseMTC＝{rf32,rf64,rf128,rf256}*(2,4,8,16,64)。
In the calculation of the system message update periods of the two systems, the default paging period is the same, and the difference is the update period system. In general, the update cycle coefficient of the eMTC technique is an integer multiple of the update cycle coefficient of the LTE technique, and therefore the update cycle of the eMTC technique is an integer multiple of the update cycle of the LTE technique. As can be seen from fig. (a) and (b), the update period of the eMTC technology is 2 times that of the LTE technology.
In addition, conventionally, the RAN device may calculate the starting time of the update period of the LTE technology by formula one:
system Frame Number (SFN) mod Tlte0 formula one
The RAN device may also calculate the start time of the update period of the eMTC technique by the following equation two:
[ (hyper frame number (HFN) × 1024+ SFN [ ]]mod TeMTC0 formula two
Due to TeMTCIs TlteThe integer multiple of the system information, therefore, after the RAN device acquires the updated resource configuration information, the RAN device may directly determine the target time for sending the system information by formula two. The target time can be guaranteed to be a common starting time of an updating period of the LTE technology and an updating period of the ETMC technology. Wherein the difference between the target time and the current time is greater than or equal to TeMTC。
After the target time is determined, the RAN equipment pushes an updating period of an LTE technology forward from the target time, and the determined first time is used as the sending time of a system message change notification corresponding to the LTE technology; and pushing forward an updating period of the eMTC technology from the target time, and taking the determined second time as the sending time of the system message change notification corresponding to the eMTC technology.
The RAN equipment sends a system message change notification when reaching the second moment; when the first time is reached, sending a system message change notice; and when the target time is reached, performing resource allocation according to the new resource allocation information, and simultaneously sending a new system message carrying the resource allocation information, as shown in fig. (c).
Further, as shown in fig. 4, since the update cycle of the LTE technology includes 6 scheduling cycles, the RAN device may repeatedly transmit the system message change notification 6 times at the frequency of the scheduling cycle between the first time and the target time. Similarly, the update cycle of the eMTC technique includes 4 scheduling cycles, and therefore, the RAN device may repeatedly transmit the system message change notification 4 times between the second time and the target time according to the frequency of the scheduling cycles.
It should be further noted that, the RAN device may repeatedly send new system messages for multiple times in corresponding update periods according to the two scheduling periods, which may specifically refer to the above description, and details are not described here again.
By the above example, when determining that the system message needs to be updated, the RAN device supporting the LTE technology and the eMTC technology first determines a start time common to update periods of the LTE technology and the eMTC technology, and validates and transmits the system message when the time is reached. Since the RAN device transmits the system message at the common starting time of the update cycle of the system messages of the multiple communication technologies, by adopting the scheme, the RAN device, the LTE terminal device and the eMTC terminal device in the cell managed by the RAN device can take effect of the new system message at the same time. Thus, the RAN equipment, the LTE terminal equipment and the eMTC terminal equipment can simultaneously adopt the same resource configuration for communication, and further the communication quality of the LTE terminal equipment and the eMTC terminal equipment can be ensured.
Based on the foregoing embodiments, an embodiment of the present application further provides RAN equipment, where the RAN equipment may be applied to a communication system as shown in fig. 2, and the RAN equipment can implement the system message sending method as shown in fig. 3 and fig. 4. Referring to fig. 5, the RAN apparatus 500 includes: a processing unit 501 and a communication unit 502, wherein:
a processing unit 501, configured to:
acquiring updated resource configuration information;
determining a target time according to the update cycle of the system messages of the plurality of communication technologies when a plurality of communication technologies are supported currently, wherein the target time is a common starting time of the update cycle of the system messages of the plurality of communication technologies;
determining the sending time of the system message change notification corresponding to each communication technology according to the update cycle of the system message of each communication technology and the target time;
control the communication unit 502 to transmit the system message change notification at the transmission timing of the system message change notification corresponding to each communication technology, respectively;
performing resource allocation according to the resource allocation information at the target time, and controlling the communication unit 502 to send a system message, where the system message includes the updated resource allocation information;
the communication unit 502 is configured to: and sending the system message change notification and the system message.
In one implementation, the plurality of communication techniques includes: long term evolution, LTE, technology and enhanced machine type communication, eMTC, technology.
In one implementation, a difference between the target time and the current time is greater than or equal to a time threshold, and a value of the time threshold is a maximum update period among update periods of system messages of the plurality of communication technologies.
In one implementation, when determining the target time according to the update cycle of the system messages of the multiple communication technologies, the processing unit 501 is specifically configured to:
