Description

PROCEDURE FOR CONFIGURING RESOURCES FOR SEMI-PERSISTENCE PLANNING OF GROUPINGS, BASE STATION AND TERMINAL FIELD OF THE INVENTION The present invention relates to the field of trunk communication linkage and, specifically, to a method of configuring backbone semi-persistence planning resources, a base station and a terminal.

BACKGROUND OF THE INVENTION A trunk link system plays an irreplaceable role in the field of professional communication of a digital communication system, due to its massive response characteristics. The existing digital trunk link communication systems mainly include: a Trunk Terrestrial Linking Radio (TETRA) system, an Integrated Enhanced Digital Network (DEN) system, a Global Open Trunk Linking (GoTa) system and a GT800 system, etc.

The existing technology of Long-Term Evolution (LTE) is a system based on single-user services, and trunk-link services based on calls from multiple users are not formulated specifically. In addition, a voice service is the most important service in the trunk link system, and therefore the voice service has its own important features, for example, a data packet is small and a transmission period is set. In the existing LTE system, the characteristics of Semi-Persistence Planning (SPS) are comparatively suitable for planning voice services.

In the LTE system, the SPS refers to an evolved NodeB (eNB) allocating fixed uplink and downlink resources for a User Equipment (UE) in a fixed period, and the UE periodically uses the resources allocated for perform data transmission. By means of the SPS, only when the SPS is activated, the SPS is reactivated and the SPS is deactivated, the eNB sends the information Downlink Control (DCI) of the carrier to the UE, by a Dedicated Downlink Control Physical Channel (PDCCH), and thus the resources of Control Channel Elements (CCE) in the PDCCH can be saved, improving by This is a resource utilization rate of the entire system.

An important feature of the trunk linking system is the lagged access of the users; lagging access refers to the fact that, in a process of establishing a trunk link service, since there is a large number of called user terminals, it is difficult to guarantee that all users of the trunk link can achieve access at the same time. each call, or the users of the trunk link can not access due to reasons such as starting and shutdown, etc., the system can postpone calling again after a certain period of time, that is, the access delay delayed, and repeat the process until the group service is released, ensuring that all group users of the trunk link can access the group successfully. However, in a case where an establishment of the trunk linking system is successful, after the service is started, once the planning is with the SPS service, only when the SPS is activated, the SPS is reactivated and the SPS is deactivated, the DCI information is sent to the UE in the SPS planning of the existing LTE technology, and a lagging access UE can not acquire planning information from the SPS in time.

Detailed descriptions will be made by the specific embodiments below.

Specific realization 1 In a dedicated trunk trunk network, a trunk trunk group makes a voice call. 1) Activation of semi-persistence planning For online users: (1) Among the users of a certain current trunking group, a plurality of them are in a quiescent state, and a plurality of trunk trunking terminals are performing data services; When a group call is established, these trunk trunk group users join the group. (2) When a user with the right to speak in the group needs to perform voice services, the base station establishes an SPS carrier for the group user, the base station allocates TSPS-RNTI resources and SPS configurations during the establishment process, it is assumed that a TSPS-RNTI value is 100, and that the configuration information includes, but is not limited to, a period of 20 ms configured by the SPS, and logical channel information to perform the SPS trunk binding services. (3) After the SPS establishment of the group has been successful, the base station immediately packages the TSPS-RNTI and the SPS configuration information into a trunk-link control channel, and a Binding Control-Channel Identifier The trunk is extended over a retention value of a logical channel in the existing LTE protocol. (4) The TSPS-RNTI and the SPS configuration information are sent to the group users through the trunk link control channel; and the group users acquire the data upon receiving the data from the trunk link control channel. (5) When there is voice data sent by the logical channel configured by the SPS, a scheduler of the base station performs the planning, encrypted by the TSPS-RNTI, and sends voice data packets, and indicates to activate the SPS service in the DCI, in the planning information; and upon receiving the DCI, the trunk linking users activate the SPS service and receive the planned voice data packets. (6) The base station will plan the voice services through the SPS logical channel with a period of 20 ms, and send them to the trunk link users on resources indicated by the DCI of the activation; the users of trunk link will also realize the reception of voice data by the logical channel of SPS, on the resources indicated by the DCI. In the process of periodically sending the data, the base station will not send the DCI, which saves the resources of the PDCCH to send the DCI. (7) When the base station activates the SPS service, the base station scheduler will send an indication of semi-persistence planning resources, in the DCI generated during activation, to a layer of RRC, the layer of RRC packages the information, and the TSPS-RNTI and SPS configuration information, in the trunk-link control channel, and the trunk-link control channel shall make a periodic sending according to a configuration period, wherein a period of the trunk link control channel may be configured in the sector of the base station, and a suitable configuration period is selected according to the actual situation.

(2) Since the base station sends the DCI to perform the activation when it activates in the group, and then does not re-send the DCI to perform the activation, these late access users can not acquire the DCI to perform the activation . (3) The base station periodically sends a TSPS-RNTI and an indication of semi-persistence planning resources in the DCI generated when an SPS carrier is activated, and SPS configuration information, by a trunk link control channel , and when these late access users receive the data from the trunk link control channel, they can acquire the TSPS-RNTI and the semi-persistence planning resources indicated in the DCI generated when the SPS carrier is activated, and the information of SPS configuration. (4) Users of delayed group access can periodically receive voice services sent by the SPS logical channel. (5) The base station will continue to make periodic shipments, according to a configuration period, by the trunk link control channel, wherein a period of the trunk link control channel can be configured in the sector of the base station, and a suitable configuration period is selected according to the actual situation. 2) Reactivation of semi-persistence planning For online users: (1) When changing the condition of a radio channel of the trunk linking group, the time and frequency resource information during the original activation can not satisfy the current condition of the radio channel, and therefore the station is required base reactivate the SPS service at this time. (2) The base station performs the reactivation operation on the group and reassigns the semi-persistence planning resources information, a base station scheduler performs the planning, encrypted by the TSPS-RNTI, and sends data packets from voice, and indicates reactivating the SPS service in the DCI in the planning information; and upon receiving the DCI, the trunk link users reactivate the SPS service and receive the planned voice data packets. (3) The base station will plan voice services over the SPS logical channel with a period of 20 ms, and send them to the trunk link users on resources indicated by the DCI of the reactivation; and the trunk link users will also perform the reception of voice data through the SPS logical channel, with the semi-persistence planning resources indicated in the DCI generated during the reactivation. In the process of periodically sending the data, the base station will not send the DCI, which saves the resources of the PDCCH to send the DCI. (4) When the base station reactivates the SPS service, a planner of the base station will send an indication of semi-persistence planning resources, in the DCI generated during reactivation, to a RRC layer, the RRC layer packages the information, and the TSPS-RNTI and SPS configuration information, in a trunk-link control channel, and the trunk-link control channel will perform periodic sending according to a configuration period, where a channel period The trunk link control can be configured in the sector of the base station, and a suitable configuration period is selected according to the actual situation.

For late access users: (1) Certain users of a trunk linking group do not join the group on time when the trunk linking group is established, due to the following reasons, including, but not limited to, the absence of signal and shutdown, and after these users have signals or start, join the group. (2) Since the base station sends the DCI to perform the activation when performing the activation in the group, and then does not forward the DCI to perform the activation, these late access users can not acquire the DCI to perform the activation. (3) The base station periodically sends a TSPS-RNTI and a semi-persistence planning resource indication, in the DCI generated during the reactivation, and SPS configuration information, for a trunk link control channel, and when these late access users receive the data from the trunk link control channel, they can acquire the TSPS-RNTI and the semi-persistence planning resources indicated in the DCI generated during the reactivation, and the SPS configuration information. (4) Users of delayed group access can periodically receive voice services sent by the SPS logical channel. (5) The base station will continue to make periodic shipments, according to a configuration period, by the trunk link control channel, wherein a period of the trunk link control channel can be configured in the sector of the base station, and a suitable configuration period is selected according to the actual situation. 3) Deactivation of semi-persistence planning (1) When the semi-persistence planning of the group reaches a deactivation condition, where the condition includes, but is not limited to, that a voice call terminates and that a silent period time is too long, a base station deactivates the group's SPS service. (2) When the base station deactivates the SPS service, DCI is sent, encrypted by a TSPS-RNTI, to notify trunk-linking users to deactivate the trunk-link SPS. (3) Trunk link users receive the DCI of the deactivation, deactivate the SPS service of the trunk link users, disable the SPS configuration information and no longer receive voice data periodically. the logical channel of SPS. (4) A scheduler of the base station informs an RRC layer of the deactivation information, and the RRC layer stops sending the TSPS-RNTI and the semi-persistence planning resources indicated in the DCI generated during the activation , and the configuration information of SPS, by the trunk control control channel, or the RRC layer stops sending the TSPS-RNTI and the semi-persistence planning resources indicated in the DCI generated during the reactivation, and SPS configuration information, through the trunk link control channel.

Specific realization 2 In hybrid network training, between a trunk link network and a public LTE network, a base station sends periodic media information to group users.
