Description

Configuration method and node supporting multi-carrier paging

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a configuration method and a node for supporting multi-carrier paging.

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). The 5G is urgently required to have an access rate comparable to that of an optical fiber, the connecting capability of billions of devices, a perfect real-time experience, and a wireless broadband access capability anytime and anywhere. 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. In future mobile network applications, the traffic demand, the number of terminals and the types of terminals will all show explosive growth trend. As one of the important scenarios and technical means of 5G, machine Type Communication (MTC) is receiving increasing attention. In the MTC topic, a sub-topic of research on Narrowband Internet of Things (NB-IoT, narrowband-Internet of Things) is proposed for the characteristics of low-cost and low-throughput type terminals: namely, the 200kHZ band is utilized to provide low throughput wireless communication services for NB-IoT low-cost terminals.

In the stage of 3gpp R13, a concept of a Multi-Carrier (Multi-Carrier) cell is proposed, that is, a cell is composed of multiple frequency points, and each frequency point/Carrier occupies a narrow band of 200khz, but only one frequency point carries narrow-band Primary and Secondary Synchronization signals (NB-PSS and NB-SSS, narrow-band-Primary Synchronization Signal/Secondary Synchronization Signal), a narrow-band Physical Broadcast Channel (NB-PBCH, narrow-band-Physical Broadcast Channel), and a System Information Block (SIB), and such frequency points are called Anchor-carriers (Anchor-carriers) or Anchor-PRBs (Anchor-Physical Resource blocks), and are collectively called as the Anchor-carriers in the present invention. The other frequency points are called Non-Anchor carriers (Non-Anchor-carriers) or Non-Anchor PRBs (Non-Anchor-PRBs, non-Anchor-Physical Resource blocks), and are collectively called Non-Anchor-carriers in the present invention, and these carriers do not carry NB-PSS/SSS, NB-PBCH, and SIBs, and only carry channels related to data traffic, such as NarrowBand Physical Downlink Control Channel (NB-PDCCH), narrowBand Physical Downlink Shared Channel (NB-PDSCH), narrowBand Physical Uplink Shared Channel (NB-PUSCH), and NarrowBand Physical Uplink Shared Channel (NB-PUSCH). Therefore, the overhead of the common channel is saved, and the number of the pilot frequency cells is reduced. In the R13 phase, paging (Paging) is carried only on the Anchor-Carrier, which results in a limited capacity for Paging.

The thirteenth embodiment of the present invention is an application example of the present invention, which is described with reference to fig. 5 to 8 on the basis of the above-mentioned embodiments.

In the existing LTE system, if data is to be transmitted to a User Equipment (UE) in an IDLE state (RRC state is RRC-IDLE), a Mobility Management Entity (MME) needs to transmit a paging message to all base stations enodebs in a Tracking Area (TA) registered by the UE, and then the enodebs transmit a paging message to notify the UE, as shown in fig. 5. The UE monitors the Paging message at a corresponding position according to a calculation formula of Paging Opportunity (PO), and initiates an RRC connection request after receiving the Paging message so as to receive downlink data. After the MME sends a paging message once, whether the paging is successfully received by the UE is judged according to whether the UE executes corresponding actions next, and if the paging is not successfully received by the UE, the user is continuously paged in the next paging cycle.

The embodiment of the invention firstly provides a multi-carrier configuration method for paging. As shown in fig. 6, in a cell corresponding to one base station eNodeB of the conventional LTE system, a Non Anchor carrier and an Anchor carrier coexist. The eNodeB informs the Non-Anchor carrier that can be used to send a paging message in the cell to the UE in a form of a Non-Anchor carrier list through broadcasting, for example, the Non-Anchor carrier list may be carried in an SIB message. In addition, the eNodeB needs to store the Non Anchor carrier list information and the Anchor carrier information together, so as to obtain the situation that the UE selects the paging carrier through calculation, for example, the list information in fig. 7 is stored. When the paging message of the UE reaches the eNodeB, the paging message can be accurately sent through the determined paging carrier.

The invention also provides a method for selecting the paging carrier by the UE, such as: the time domain factor can be considered to be added when the UE selects the paging carrier, so that the phenomenon that the UE fixedly selects a certain carrier, and the load of the certain carrier is always heavier and the load of the certain carrier is always lighter can be avoided. After the time domain factor is added, the UE may belong to different carriers in different time domain positions. The time domain factor is selectable, such as a system frame number SFN and a hyper frame number H-SFN, specifically:

when the H-SFN is selected as the time domain selection parameter, the formula for selecting the paging carrier by the UE may be:

P _NB ＝floor((UE-ID+H-SFN)/Y1)modN _NB

or;

P _NB ＝(floor(UE-ID/Y1)+H-SFNmodY2+T _eDRX,H modk)modN _NB

or:

P _NB ＝floor(UE-ID/Y1+H-SFNmodY2+T _eDRX,H modk)modN _NB

or:

P _NB ＝(floor(UE-ID/Y1)+floor(H-SFN/Y3)+T _eDRX,H modk)modN _NB

or:

P _NB ＝floor(UE-ID/Y1+H-SFN/Y3+T _eDRX，H modk)modN _NB

or:

P _NB ＝floor(UE-ID/Y1+H-SFNmodY2+m1)modN _NB

or

P _NB ＝(floor(UE-ID/Y1)+floor(H-SFN/Y3)+m2)modN _NB

Or

P _NB ＝floor(UE-ID/Y1+H-SFN/Y3+m2)modN _NB

Or

P _NB ＝floor((UE-ID+H-SFN)/Y1+T _eDRX,H mod k)modN _NB

When SFN is selected as the time domain selection parameter, the UE selects the paging carrier formula as follows:

P _NB ＝floor((UE-ID+SFN)/Y1)modN _NB

or:

P _NB ＝(floor(UE-ID/Y1)+SFNmodY2+T _eDRX,H modk)modN _NB

or:

P _NB ＝floor(UE-ID/Y1+SFNmodY2+T _eDRX,H modk)modN _NB

or:

P _NB ＝(floor(UE-ID/Y1)+floor(SFN/Y3)+T _eDRX,H modk)modN _NB

or:

P _NB ＝floor(UE-ID/Y1+SFN/Y3+T _eDRX,H modk)modN _NB

or:

P _NB ＝(floor(UE-ID/Y1)+SFNmodY2+m1)modN _NB

or:

P _NB ＝(floor(UE-ID/Y1)+floor(SFN/Y3)+m2)modN _NB

or

P _NB ＝floor(UE-ID/Y1+SFN/Y3+m2)modN _NB

Or

P _NB ＝floor((UE-ID+SFN)/Y1+T _eDRX,H mod k)modN _NB

Optionally, when Y1= N × Ns and Y2=1, k =1, the selection by the UE of the carrier carrying the paging message may be represented as:

the maximum value of nxns in NB-IoT is 4096, so in order for there to be a packet of UEs on each narrowband, then the UE-ID should be extended as: UE-ID = IMSI mod (4096 × k1 × N) _NB ) Wherein k1 is 1 to floor ((10) ¹⁰ -1)/(4096×N _NB ) ) is selected from the group consisting of (i) and (ii).

Optionally, when Y2=1, the ue selects a paging carrier, which may be represented as:

The eNodeB contains two modules:

(2) A paging message sending module: the eNodeB will send the paging message on the calculated paging carrier. The flow of the above calculation and transmission of the eNodeB is shown in fig. 8.

The MME comprises a module:

the sending module of the paging message: the MME needs to send a paging message to all enodebs within a Tracking Area (TA) registered by the UE.

By adopting the method and the system of the embodiment of the invention, the limitation of paging capacity can be reduced on one hand by configuring the Non Anchor carrier which can be used for transmitting the paging message for the user equipment and providing the method for the user equipment to select the paging carrier; on the other hand, the terminals can be distributed on each paging carrier relatively uniformly to monitor the paging messages, so that the purpose of load balancing is achieved.
