Description

Cluster paging method, device, cluster terminal, network equipment and storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a trunking paging method, a trunking device, a trunking terminal, a network device, and a storage medium.

Background

The cluster communication system is a special wireless communication system developed for meeting the demands of industry command and dispatch and applied to various industries, and is widely applied to the fields of public safety, transportation, petrochemical industry, business and military. With the continuous development of the fifth generation mobile communication (the 5 ^th generation, 5G), the trunking system also evolves so as to better meet the requirements of industry users on the novel broadband multimedia trunking service.

The cluster function is added on the basis of 5G, so that the 5G private network has the advantages of large bandwidth, wide connection, low time delay, high safety and the like. The trunking group call service is a point-to-multipoint service, including trunking voice group call service and trunking video group call service, and is a very important service in trunking communication systems, and industry users are required to realize rapid call establishment. The 5G requires that User Equipment (UE) in any of radio resource control (Radio Resource Control, RRC) states be able to answer the group call, and thus cluster paging is an indispensable procedure in the establishment of the group call.

In addition, when the group call of the trunking communication system starts, because part of users of the called group cannot receive the group call paging message because of not being in a service area or being powered off, and the like, all terminals in the group of each group call cannot be ensured to be accessed once. The delay access is used as a very important function in the trunking communication system and is used for joining the call again by the terminal which fails to access when the call starts, wherein the delay access function can periodically send the group calling paging message and the group calling service establishment request message until the group calling is released, and the users of the trunking group can join the group calling communication later.

Table 1 comparison of three paging messages

Currently, in a 5G New air interface (NR) communication system, a paging application scenario includes paging initiated by a core network, paging initiated by a base station (Next Generation Node B, gNB), and notification of system message update initiated by the gNB. As shown in table 1, paging initiated by the core network is applicable to a UE in a radio resource control IDLE state (Radio Resource Control IDLE, rrc_idle), and the paging range is a tracking area where the UE is currently registered; the gNB initiated paging is applicable to the UE in a radio resource control INACTIVE state (Radio Resource Control Inactive, RRC_INACTIVE), and is triggered when new downlink data or signaling is sent to the UE; the notification of the system message update initiated by the gNB is applicable to UEs in any RRC state (rrc_idle, rrc_inactive or rrc_connected), where the update of the system message is called a short message in the RRC protocol, RRC information is contained in a physical downlink control CHannel (Physical Downlink Control chnnel, PDCCH) CHannel, and the PDCCH CHannel carrying these three paging messages scrambles a common paging radio network temporary identity (Paging Radio Network Temporary Identifier, P-RNTI) configured in the cell. In addition, the paging message initiated by the core network and the paging message initiated by the gNB may include a plurality of paging records, where each paging record includes a paging message for a UE.

The transmission mechanism of paging messages is specified in The third generation partnership project organization (The 3 ^th Generation Partnership Project, 3 GPP) 5G related protocol. To reduce UE power and increase battery usage time, 5G paging supports discontinuous reception (Discontinuous Reception, DRX).

Each wake-up period is called a DRX cycle, there are multiple Paging frames (PAGING FRAME, PF) in one DRX cycle, one PF corresponds to multiple Paging Occasions (POs), and one UE receives a Paging message on one PO, where i_s is a number of one PO corresponding to the PF, for example, i_s of the UE is used to instruct the UE to receive the Paging message in the i_s+1th PO in the PF.

The 5G protocol calculates PF and i_s using equations (2) and (3):

(SFN+PF_offset)modT＝(TdivN)*(UE_IDmodN)(2)

i_s＝floor(UE_ID/N)mod Ns (3)

Wherein, T represents paging cycle, N represents PF number in paging cycle T, PF_offset represents radio frame offset, SFN represents frame number of radio frame corresponding to PF, UE_ID represents identification of UE, value is 5G-S-TMSI mod 1024, ns represents PO number in PF, and values are 1, 2 and 4.

In 5G, the PF represents a system radio frame, but the POs is no longer included in the PF, but one PF corresponds to a plurality of POs, and all PDCCH listening occasions between two PFs are PDCCH listening occasions that make up the POs. The paging search space parameter indicates a corresponding paging monitoring occasion (Paging monitoring occasion, PMO) for the UE, and CORESET of the PDCCH receiving the P-RNTI scrambling is determined according to the control resource set (Control Resource Set, CORESET) corresponding to the search space parameter.

Thus, paging occasions of the UE in the 5G communication system are related to the user equipment identity (User EquipmentIdentity document, ue_id). If paging related parameters of all UEs in the cell are configured to be the same value, but the 5G temporary mobile subscriber identity (the 5 ^th generation S-Temporary Mobile Subscriber IDentity, 5G-S-TMSI) of each UE is different, the ue_ids calculated according to formulas (2) and (3) are different, and paging occasions corresponding to each UE are also different; if the existing 5G paging transmission mechanism is directly used to page all UEs in the cluster group, the overall paging time is too long and the overhead of air interface resources is too large.

In summary, in a 5G communication system, paging occasions of UEs are related to ue_id, and an existing 5G paging transmission mechanism is used to page all UEs in a trunking group, so that the overall paging time is too long, the overhead of air interface resources is too large, and how to implement trunking group paging and late access functions based on the 5G trunking communication system becomes a problem to be solved urgently.
