Problems solved by technology

[0003] CDMA (Code Division Multiple Access, Code Division Multiple Access) 2000 professional trunking system paging transmission method is based on the terminal IMSI (International Mobile Subscriber Identification Number, International Mobile Subscriber Identification Number) to hash, select a specific time slot to send, in the group When there are many monitoring users in the group, the amount of paging is large, and the IMSI needs to be brought to the BSC (Base Station Controller, Base Station Controller) by the PDS (PTT Dispatch Server, PTT Dispatch Server), and the BSC needs to have a certain amount of overhead for saving

Embodiment 1

[0071] This embodiment describes a method for sending cluster paging in an LTE system, such as figure 1 shown, including the following steps:

[0072] Step 10, the base station receives the group paging request;

[0073] Step 11: Send a paging message to the trunking terminal in the cell at a predetermined paging time slot, and the paging message includes the group ID of the group that needs to be paged.

[0074] For the cluster service, the paging message monitored by each terminal in the group is the same, and there is no need to send a paging message separately for each terminal. Therefore, the design of this application includes the group identifiers of all groups that need to be paged in a paging message, which can reduce the number of paging message transmissions, reduce the header overhead of each protocol layer when paging is sent in a distributed manner, and improve system capacity , to reduce the complexity of system implementation.

Embodiment 2

[0090] This embodiment describes a method for sending cluster paging in an LTE system, such as image 3 shown, including the following steps:

[0091] Step 20, the trunking terminal monitors the paging message;

[0092] Step 21, after listening to the paging message, judging that the group identifier contained in the paging message is the same as the group identifier of the group to which the terminal belongs, then accessing the group service and sending a paging response to the base station, Either not sending a paging response to the base station, or judging whether to send a paging response to the base station according to the paging response identification information in the paging message.

[0093] By performing different processing on the way in which the terminal sends the paging response, different system requirements can be met.

[0094] If it is judged that the group identifier contained in the paging message is different from the group identifier of the terminal, ...

application example 1

[0111] Such as Figure 4 As shown, in this example, the calling party and the called party are not in the same cell, and the called trunking terminal is in an idle state. Send a paging response immediately, including the following steps:

[0112] Step 101, the base station determines the trunking paging time slot and notifies the trunking terminal (such as notifying the terminal in the SIB, but not limited to the SIB);

[0113] The trunking paging time slot is used for trunking terminals to monitor trunking paging.

[0114] Step 102, when the group call is established, the base station combines the paging messages that need to be sent to each group in the cell, and sends them to the trunking terminals in the cell in the determined trunking paging time slot. The paging message carries Group ID (GroupID, or group number) of the group to be paged;

[0115] Preferably, the paging message may also carry other group information, such as T-RNTI (Trunking-RadioNetwork Temporary Ide...

Abstract

The embodiments of the present invention disclose a method and a corresponding apparatus for sending and receiving the trunking paging in a LTE system. The method for sending the trunking paging includes: after receiving a group paging request, a base station sending a paging message to trunking terminals in a present cell in a predetermined paging time slot, wherein the paging message includes a group identification of a group needing to be paged. A base station for sending the trunking paging includes a receiving module and a sending module. A method for receiving the trunking paging includes: after monitoring a paging message, when determining that a group identity included in the paging message is the same as a group identity of the group to which the present terminal belongs, a trunking terminal accessing the group service, and sending a paging response to base station, or not sending a paging response to base station, or judging whether to send a page response to the base station or not according to paging response identification information in the paging message. A trunking terminal for receiving the trunking paging includes a monitoring module, a judging module and a group service processing module.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and a corresponding device for sending and receiving group paging in an LTE (Long Term Evolution, long-term evolution) system. Background technique [0002] LTE is a 3GPP long-term evolution project and the largest new technology research and development project launched by 3GPP in the past two years. The core technology can be regarded as "quasi-4G" technology. The main advantages of LTE are high peak rate, low system delay, and support for flexible configuration of bandwidth. For example, a spectrum bandwidth of 20MHz can provide a peak rate of 100Mbps downlink and 50Mbps uplink, and the internal one-way transmission delay of the user plane is less than 5ms. It supports flexible configuration of bandwidth from 1.25MHz to 20MHz. Carrier aggregation technology can also be used to further improve cell capacity. LTE has broad application prospects. ...
