Description

A group paging method, system and device

technical field

The embodiments of the present invention relate to the technical field of communications, and in particular to a group paging method, system and device.

Background technique

At present, equipment and terminals of some manufacturers of the CDMA (Code-Division Multiple Access) 2000 communication system already support voice service, data service, and trunking service functions at the same time. In the CDMA2000 communication system, the access system generally adopts the time slot paging scheme for paging the terminal, and calculates the paging time slot based on the hash calculation of the user IMSI (International Mobile Subscriber Identification Number, global mobile subscriber identification number). In addition, the access system provides non-slot paging and broadcast paging methods for other functions. In the trunking communication system, there are multiple users in a group, and a user can belong to multiple groups; for the group call establishment process, it is necessary to initiate paging for each user in the group, so that each user can access the system , to complete the cluster business.

A paging method provided by the prior art is based on user paging, that is, the access system performs time slot paging for each user terminal in the group according to the CDMA2000 standard. As shown in Figure 1, the paging of each user terminal The paging slot (PGSLOT, Paging Slot) is determined based on the hash calculation of the IMSI of the user terminal, and the paging message adopts the General Page Message in the CDMA2000 standard.

However, in the above paging method, the access system initiates time slot paging for each user in the group one by one, and the access system initiates a successful paging, the total access delay of the group users, that is, from the group The time taken by the first user in the group to connect all users in the group depends on the user access in the largest time slot. Therefore, the amount of paging signaling messages required by this method increases with the increase of the number of group users, and the total access delay of group users is relatively long.

Another paging method provided by the prior art is based on broadcast paging, that is, the access system performs paging at slot 0 (slot 0) according to a fixed broadcast cycle. As shown in Figure 2, the access system performs paging at slot 0 Each user in the group receives the same group paging message, and the user who receives the group paging message determines whether the group to which the user belongs initiates paging.

However, since the above-mentioned paging method performs paging at time slot 0 according to a fixed broadcast cycle, and the group paging message includes information such as a group identifier and a group access service channel, wherein the group access service channel information includes Frequency band (BAND_CLASS), frequency point (CDMA_FREQ), front and reverse channel wireless configuration (FOR_RC and REV_RC), frame offset (FRAME_OFFSET), channel Walsh (Walsh) code (CODE_CHAN) and other fields, so a single paging channel The number of groups that can accept simultaneous group calls is limited by the bearer load of a single time slot; when the number of groups exceeds this limit, paging messages for redundant groups will be scheduled to be sent in subsequent broadcast cycles, causing some groups to access The delay is long.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

As shown in Figure 3, it is a flow chart of the cluster paging method in the embodiment of the present invention, including:

Step S301, receiving a cluster paging indication message sent by an access system, the cluster paging indication message includes group identification information, and the group identification information includes identifications of one or more groups.

Wherein, in an implementation manner of the embodiment of the present invention, the access system determines the sending time slot for the paging message of the group that has not yet been sent on a single paging channel, and then assembles the group identifier and the determined sending time slot into a cluster The paging indication message, therefore, the cluster paging indication message may further include the sending time slot of the paging message of the group corresponding to the group identification information. The cluster paging indication message belongs to the manufacturer's internal air interface specification. The cluster paging indication message is sent in slot 0 of the broadcast cycle and before the group paging message, as shown in Figure 4. The group paging instruction message carries the identification of one or more groups, and the group identification information corresponds to the sending time slot of the paging message of the group, and does not include the group access service channel information, so that the group capacity is greatly improved. promote.

In another implementation manner of the embodiment of the present invention, the access system determines the time slot for sending the paging message of the group corresponding to the group identification information according to a predetermined calculation rule within the broadcast period according to the group identification information. The embodiment of the present invention does not limit the predetermined calculation rule, for example, it may be a HASH (hash, hash) calculation rule.

Step S302, when it is determined according to the group identification information that the trunking terminal's group is included in the trunking paging instruction message, the paging message of the group to which the trunking terminal belongs is received from the access system.

After the trunking terminal receives the trunking paging indication message in time slot 0 of the broadcast period, it judges whether the trunking paging indication message includes the group to which the trunking terminal belongs. If the trunking paging indication message does not include the group to which the trunking terminal belongs, the trunking paging process ends.

When the cluster terminal determines that the cluster paging indication message includes the group to which the cluster terminal belongs, the cluster terminal receives the paging message of the group to which the cluster terminal belongs sent by the access system. Specifically, the following two methods can be used:

(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 sent by the access system in the above-mentioned determined receiving time slot. or,

(2) If the paging instruction message does not carry the sending time slot of the paging message, the trunking terminal determines the paging time slot 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 according to a predetermined calculation rule. For the receiving time slot of the message, 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 rule. Then, the trunking terminal receives the paging message of the group to which the trunking terminal belongs sent by the access system in the above-mentioned determined receiving time slot.

If the access system does not send the trunking paging indication message in time slot 0 of the broadcast cycle, since the access system will still perform paging in fixed time slot 0 of the broadcast cycle, the trunking terminals in the group will not receive the trunking paging indication When receiving a paging message, the trunking terminal in the group can also receive the paging message of the group to which the trunking terminal belongs.
