Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a cluster paging method, a cluster paging system and a cluster paging device.
Background
At present, part of factory equipment and terminals of a CDMA (Code-Division Multiple Access) 2000 communication system support voice service, data service, and trunking service functions at the same time. In the CDMA2000 communication system, the access system generally employs a time slot paging scheme for paging a terminal, and performs hash calculation on a paging time slot based on an International Mobile Subscriber identity Number (IMSI). In addition, the access system provides non-slotted paging, broadcast paging, for other functions. In a trunking communication system, a plurality of users exist in one group, and one user can belong to a plurality of groups; for the group call establishment process, it is necessary to initiate paging for each user in the group, so that each user accesses the system to complete the trunking service.
A Paging method provided in the prior art is based on user Paging, that is, an access system performs Slot Paging on each user terminal in a group according to a CDMA2000 standard, as shown in fig. 1, a Paging Slot (PGSLOT) of each user terminal is determined by performing hash calculation based on an IMSI of the user terminal, and a Paging Message adopts a General Page Message in the CDMA2000 standard.
However, in the above paging method, the access system initiates the time slot paging to each user in the group one by one, the access system initiates a successful paging, and the total group user access delay, i.e. the time from the 1 st user in the group calling to the access of all users in the group, depends on the user access of the maximum time slot. Therefore, the amount of paging signaling messages required by the method is increased along with the increase of the amount of group users, and the total access delay of the group users is longer.
Another paging method provided in the prior art is based on broadcast paging, that is, an access system performs paging in a slot 0 according to a fixed broadcast period, as shown in fig. 2, the access system sends a trunking paging message in the slot 0, each user in a group receives the same trunking paging message, and a user receiving the trunking paging message determines whether the group to which the user belongs initiates paging.
However, since the paging method performs paging in 0 time slot according to a fixed broadcast period, and the group paging message includes information such as group identification, group access traffic channel, and the like, where the group access traffic channel information includes fields such as BAND _ CLASS, frequency (CDMA _ FREQ), forward/reverse channel radio configuration (FOR _ RC and REV _ RC), FRAME OFFSET (FRAME _ OFFSET), and channel Walsh CODE (CODE _ CHAN), the number of groups that can receive simultaneous group calls on a single paging channel is limited by the load of a single time slot; when the number of groups exceeds this limit, paging messages for redundant groups are scheduled to be sent in subsequent broadcast periods, resulting in a longer access delay for some of the groups.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 3, a flowchart of a trunking paging method according to an embodiment of the present invention includes:
step S301, receiving a trunking paging indication message sent by the access system, where the trunking paging indication message includes group identification information, and the group identification information includes one or more group identifications.
In an implementation manner of the embodiment of the present invention, the access system determines a sending time slot for a paging message of a group that has not been sent on a single paging channel, and then assembles a group identifier and the determined sending time slot into a trunking paging indication message, so that the trunking paging indication message may further include the sending time slot of the paging message of the group corresponding to the group identifier information. The cluster paging indication message belongs to an air interface specification inside a manufacturer, and is sent in slot 0 of a broadcast period and before the paging message of a group, as shown in fig. 4. The cluster paging indication message bears the identification of one or more groups and the sending time slot of the paging message of the group corresponding to the group identification information, and does not contain the information of the group access service channel, so that the group capacity is greatly improved.
In another implementation manner of the embodiment of the present invention, the access system determines, according to the group identification information and according to a predetermined calculation rule, a transmission timeslot of the paging message of the group corresponding to the group identification information in the broadcast period. The embodiment of the present invention does not limit the predetermined calculation rule, for example: rules may be computed for HASH.
Step S302, when the cluster paging indication message is determined to contain the cluster terminal group according to the group identification information, the paging message of the cluster terminal group sent by the access system is received.
After the trunking terminal receives the trunking paging indication message in the 0 time slot of the broadcast cycle, it determines whether the trunking paging indication message contains the group to which the trunking terminal belongs. If the trunking paging indication message does not contain the group to which the trunking terminal belongs, the trunking paging process is ended.
When the trunking terminal determines that the trunking paging indication message contains the group to which the trunking terminal belongs, the trunking terminal receives the paging message of the group to which the trunking terminal belongs, which is sent by the access system. Specifically, the following two methods can be adopted:
(1) if the paging indication message carries the sending time slot of the paging message, the trunking terminal determines the receiving time slot of the paging message of the group to which the trunking terminal belongs according to the sending time slot of the paging message. Then, the trunking terminal receives the paging message of the group to which the trunking terminal belongs, which is sent by the access system, in the determined receiving time slot. Or,
(2) if the paging indication message does not carry the sending time slot of the paging message, the trunking terminal determines the receiving time slot of the paging message of the group to which the trunking terminal belongs according to the group identification information of the group to which the trunking terminal belongs and a predetermined calculation rule, wherein the predetermined calculation rule is the same as the calculation rule adopted by the access system when determining the sending time slot of the paging message of the group corresponding to the group identification information, for example: HASH calculation rules. Then, the trunking terminal receives the paging message of the group to which the trunking terminal belongs, which is sent by the access system, in the determined receiving time slot.
If the access system does not send the trunking paging indication message in the 0 time slot of the broadcast cycle, because the access system still performs the fixed 0 time slot paging of the broadcast cycle, the trunking terminal in the group can also receive the paging message of the group to which the trunking terminal belongs when the trunking terminal in the group does not receive the trunking paging indication message.
After receiving the paging message of the group to which the trunking terminal belongs, the trunking terminal completes the trunking service according to the received paging message.
In the trunking paging method, the access system sends the trunking paging indication message carrying the group identification information, the group identification information comprises one or more group identifications, and the trunking paging indication message does not contain the group access service channel information, so the group capacity of the trunking service is improved, the paging channel resource and the power resource are fully utilized, and the service volume is improved.

the access system 51 is configured to send a trunking paging indication message, where the trunking paging indication message includes group identification information, and the group identification information includes an identifier of one or more groups.
The trunking terminal 52 is configured to receive the trunking paging indication message sent by the access system 51, and receive the paging message of the group to which the trunking terminal 52 belongs, which is sent by the access system 51 when it is determined that the trunking paging indication message includes the group to which the trunking terminal 52 belongs according to the group identification information.
In the embodiment of the present invention, the access system 51 carries group identification information including one or more group identifications in a trunking paging indication message, and sends the trunking paging indication message to the trunking terminal 52 in slot 0 of a broadcast cycle, where the trunking paging indication message is sent before a paging message of a group. After the trunking terminal 52 receives the trunking paging indication message in the 0 timeslot of the broadcast cycle, it determines whether the trunking paging indication message includes the group to which the trunking terminal 52 belongs. If the trunking paging indication message does not include the group to which the trunking terminal 52 belongs, the trunking paging procedure is ended.
If the trunking terminal 52 does not receive the trunking paging indication message in the 0 slot of the broadcast cycle, the trunking terminal 52 will continue to receive the paging messages of the group to which the trunking terminal 52 belongs.
After receiving the paging message of the group to which the trunking terminal 52 belongs, the trunking terminal 52 completes the trunking service according to the received paging message.
In the trunking paging system, the access system 51 sends a trunking paging indication message carrying group identification information, where the group identification information includes one or more group identifications, and the trunking paging indication message does not include group access service channel information, so that the trunking terminal 52 receives a paging message of a group to which the trunking terminal 52 belongs according to the trunking paging indication message.

As shown in fig. 7, the message receiving module 523 may include:
a time slot determination submodule 5231 is used for determining the receiving time slot of the paging message of the group to which the trunking terminal 52 belongs. Specifically, the following two methods can be adopted:
(1) determining a receiving time slot of the paging message of the group to which the trunking terminal 52 belongs according to the sending time slot of the paging message of the group to which the trunking terminal 52 belongs, which is carried by the trunking paging indication message received by the indication receiving module 521; or,
(2) according to the group identification information of the group to which the cluster terminal 52 belongs, the receiving time slot of the paging message of the group to which the cluster terminal 52 belongs is determined according to a predetermined calculation rule, which is the same as the calculation rule adopted by the access system 51 when determining the sending time slot of the paging message of the group corresponding to the group identification information, for example: rules may be calculated for HASH;
