Description
Technical Field
The present invention relates to, but not limited to, wireless communication technologies, and in particular, to a method, an access network element, a user equipment, and a system for implementing system message update.
Background
Machine to Machine (M2M) communication is a fifth generation mobile communication technology (5G, 5)thGeneration), and is an important application field of future wireless communication. In the M2M topic, the third generation partnership project (3GPP) has proposed a research sub-topic of a narrowband Internet of Things (NB-IoT) system aiming at the characteristics of low-cost and low-throughput type terminals, and aims to construct a system similar to Long Term Evolution (LTE) in a frequency band of 200 kilohertz (KHz) to provide low-throughput wireless communication services for low-cost terminals.
The System Information (SI) is a common message of the cell and is used for indicating the system parameters of the cell, and the User Equipment (UE) residing in the cell must keep consistent with the latest system message; the system messages are typically sent on a broadcast channel of the cell. In LTE and NB-IoT systems, system messages are divided into two categories, namely, a Master Information Block (MIB) and a System Information Block (SIB), and the SIB is subdivided into different numbered system message blocks, namely, SIB1, SIB2, and SIB 3. The blocks of system messages other than the SIB1 constitute one or more SIs. The SIB1 carries scheduling information of the composed SIs, where the scheduling information is used to indicate the number of system message blocks included in each SI, the transmission period, and the time window for the UE to receive the SIs.
Fig. 1 is a schematic diagram illustrating an update of a conventional system message, where as shown in fig. 1, the system message is updated according to a mechanism of a modification period (BCCH modification period, referred to herein as a modification period) of a broadcast common control channel, and when the system message needs to be changed, a base station first carries a UE system message update indication in a paging message (paging message) in a first modification period; then, the UE starts to send the updated system message in the second modification period (the second modification period is a subsequent modification period of the first modification period), and receives the updated system message in the second modification period after receiving the paging message carrying the update indication. In addition to the system messages that need to change rapidly, other system messages remain unchanged during the second modification period. According to the latest 3GPP discussion, the MIB message carries a main system message value tag (main value tag of system information), which is updated when part of the SI or SIB changes, and is used to indicate that at least part of the SI or SIB has been or is about to be updated, and is scheduled and transmitted according to an agreed modification period and time-domain/frequency-domain resources. The SIB1 carries the value tag of each system message SI, and is scheduled and transmitted according to an agreed modification period and time-domain and frequency-domain resources. When the system message is changed, the value tag in the MIB is correspondingly updated; meanwhile, the value tag of the SI in SIB1 is also updated accordingly, that is, the value tag corresponding to the SI that has been changed is updated, while the value tag of the SI that has not been changed remains unchanged. Currently, numerical labels are mainly used in the following two scenarios: when the UE is out of the coverage area of the cell and reenters the cell within the appointed time, the UE compares a value tag value of a system message stored by the UE with a value tag value carried in the current system message to judge whether the system message is changed or not, and when the system message is determined to be changed, the UE reads the system message of the cell again; in a second scenario, if the UE does not receive the paging message in a modification period, the UE needs to read a value tag of the system message in the next modification period, so as to determine whether the system message is changed.
In a narrow-band system of the Internet of things, UE has extreme requirements on power saving; the service life of the terminal can be extended by saving power consumption. According to the existing system message updating method, if the paging message received by the UE contains a system message Modification indication (system Info Modification), the UE needs to re-read the SIB1 and all the system messages to update the system message, which will cause a lot of power consumption of the UE and affect the service life of the UE.

Application example 1
Example of the present application
Fig. 8 is a flowchart of a method for updating system messages according to a first application example of the present invention, as shown in fig. 8, including:
step 800, the access network element sends the update indication information of the system message in a first modification period; here, the first modification period may optionally be a previous modification period of the system message update;
in the present application example, the update indication information includes a main system message value tag and/or a value tag of an SI or SIB that needs to be updated; the update indication information is transmitted through a paging message, a Radio Resource Control (RRC) message, or Downlink Control Information (DCI) carried by a media Control layer (MAC) Control element, or a physical Downlink Control channel (pdcch).
Wherein, if the system message update indication information is sent by using the DCI carried by the PDCCH, the DCI uses a Radio Network Temporary Identifier (RNTI) dedicated for paging or an RNTI agreed by other protocols to perform scrambling.
Step 801, the UE receives the update indication information and updates the local save value tag according to the update indication information.
When the update indication information includes the main system message value tag and the value tag of the SI or SIB that needs to be updated, the main system message value tag and the value tag of the SI or SIB that needs to be updated are written in different positions of the update indication information according to a standard.
Step 802, the network element of the access network sends a system message in a second modification period; the second modification period refers to a next modification period of the first modification period.
Step 803, the UE reads the SI or SIB to be updated from the system message according to the update indication information in the second modification period or the modification period after the second modification period;
in the application example, when the SI or SIB to be updated can be updated according to the scheduling period, that is, the SI or SIB to be updated can be changed when any one is scheduled; that is, the UE reads at the scheduled time of the next corresponding SI or SIB according to the update indication information. For SI or SIB that does not indicate a change, the UE does not need to read, i.e., keep the SI or SIB of the non-updated portion that the UE locally holds to continue to be valid.
Various combinations of the above are within the scope of the invention.
Application example 2
In the application example, the system message to be updated comprises the MIB, the SIB1 and several SIs; the MIB carries a main system message value tag, and the SIB1 carries the value tag of each SI.
In the first modification period (P1), the value of the system message value in the MIB is V-MIB-1, and the values of the SIB1 carrying SI1 and SI2 are V-SI1-1 and V-SI2-1, respectively.
Fig. 9 is a flowchart of a method for updating a system message according to a second application example of the present invention, as shown in fig. 9, including:
step 900, the access network element sends the update indication information of the system message through the paging message in the first modification period; that is, in the present application example, the update indication information is carried in a paging message and sent to the UE, and the sending of the paging message follows the paging message sending rule defined by the system.
The update indication information includes the following parts or all of the contents:
a main system message value tag, and/or value tag information of an SI to be changed, and/or update indication information of an SIB 1; wherein,
in the application example, when the main system message value tag is included, the value tag value is a value tag value V-MIB-2 in the updated MIB.
Value tag including SI to be changed; in the present application example, it is assumed that SI1 is about to be updated, the update indication information carries a value tag information element of SI1, which has a value of V-SI1-2, and V-SI1-2 is the value tag value of SI1 after updating; the UE saves V-SI1-2 as the value tag value of SI 1.
When the update indication information of the SIB1 is included, the update indication information of the SIB1 is defined as an indication whether the UE needs to update the SIB1 message or an indication whether the change occurs in the SIB1 except for the value tag carried in the SIB 1; the UE determines from this information whether to receive the SIB1 message in the next modification period. In the present application example, assuming that the SIB1 message has no other change except for the value tag value carried by the SIB1 message, the system message update indication information indicates that the UE does not need to update the SIB1 message.
Step 901, the UE receives update indication information of the system message; the method for receiving the system message update indication by the UE is different because the access network element uses different sending methods. The prior art or other technical means possible in the future can be applied to the implementation of the method of the invention.
In this application example, if the update indication information includes the primary system message value tag, when the UE receives the update indication information, the UE covers a value of the primary system message value tag that is locally saved according to the update indication information; if the update indication information includes the value tag of the SI or SIB needing updating, the UE receives the update indication information that the value tag value of the corresponding SI locally saved is covered according to the update indication information, in this example, the UE saves V-SI1-2 as the value tag value of system message SI 1.
Step 902, in the second modification period of the system message, the access network element sends the system message; this application example second modification period is the next modification period of the first modification period.
Specifically, the system messages include MIB, SIB1, SI1, SI2, and the like; wherein,
the MIB carries the value tag of the updated whole system message, namely V-MIB-2.
The SIB1 message carries value tag information of the updated SI, namely V-SI1-2 and V-SI 2-1; since SI2 has not been changed, the value tag of SI2 has not been changed.
SI1 is an updated message, and SI2 has no change from P1.
Step 903, the UE updates the system message or the system message block that needs to be updated according to the update indication information in the second modification period or the modification period after the second modification period; in particular, the method comprises the following steps of,
the UE decides whether to receive the SIB1 message according to the update indication information. In this application example, the UE does not update the SIB1 message.
The UE receives the SI message with the change according to the update indication information, in this application example, the UE only needs to receive the SI1 message; since SI2 is not updated, the UE does not need to receive the SI2 message in this application example.
It should be noted that, in the present application example, the paging message carries the primary system message value tag and/or the value tag of each changed SI, the primary system message value tag is carried in the MIB, and the value tag of each SI is carried in the SIB1 as a precondition. If in practical application, the system message is only one of the two value tags, and the update indication information of the application example only needs to carry a corresponding part of the information, so that the purpose of saving power of the UE can be achieved.
For example, in practical applications, the MIB or SIB does not carry the main system message value tag, and the main system message value tag does not need to be indicated in the system message update indication information.
As an optimization example of the above actual application example, SIB1 carries the value tag of each SI, and system information update indication information indicates that SIB1 needs to be updated, so the system information update indication information does not include the value tag of the SI or SIB that needs to be updated and update indication information of each SI or SIB. In this case, the UE can obtain the value tag of each SI by reading the updated SIB1, and further can know the information of the SI that needs to be updated specifically by comparing the value tag of each SI in the received SIB1 with the value tag value of each SI stored locally, thereby achieving the same power saving purpose.
In this optimized use case, if the scheduling information of each SI carried in the SIB1 changes, but the actual SI information content does not change, the value tag of the corresponding SI does not need to be updated.
Although the embodiments of the present invention have been described above, the above description is only for the convenience of understanding the present invention, and is not intended to limit the present invention. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
