Embodiment 1

[0058] In order to use the LTE channel to transmit the trunking paging message, so that the trunking user can be paged by the trunking network, so as to realize the call establishment of the trunking service, a new downlink logical channel trunking paging channel (TPCCH) is added to transmit the trunking paging signaling. The trunking terminal needs to know the resource configuration information of the TPCCH, for example, the sending period of the TPCCH and the sending time of the TPCCH, in order to obtain the signaling on the TPCCH. TPCCH common resource configuration information at least includes: TPCCH channel transmission period, TPCCH channel subframe transmission time information.

[0059] In this embodiment, a new system information block type SIBX is defined for carrying TPCCH resource configuration information, and the content of SIBX is specifically as follows:

[0060] {

[0061] TPCCH resource configuration information;

[0062]}

[0063] The TPCCH resource confi...

Embodiment 2

[0083] Random access is an access procedure for a UE before it starts communicating with the network. A physical layer random access channel (PRACH) is used to transmit random access resources, that is, a random access preamble (Random Access Preamble).

[0084] LTE random access procedures can be divided into contention-based (that is, there is a risk of collision) and non-contention-based. In the contention-based random access process, the UE will randomly select a random access preamble to send. Obviously, there is a possibility that multiple UEs may send the same preamble, and the eNB will adopt a conflict resolution process to deal with this problem. In the non-contention-based random access process, eNB can avoid collisions by assigning dedicated preambles to UEs. Obviously, this method is more efficient than contention-based methods, which is an unavoidable problem for handovers with strict time constraints. neglected factors.

[0085] For each cell, there are fixed 6...

Embodiment 3

[0116] When the trunking service and common LTE service are networked in the same cell in the public network environment, the downlink trunking service and downlink common LTE service need to have the concurrent scheduling function. To this end, the system can divide the resource pool into time-frequency resources for scheduling clusters and time-frequency resources for ordinary LTE in a time-division or frequency-division manner. A graph is a scheduling graph.

[0117] When there are only LTE services in the system, the cluster scheduling map is invalid.

[0118] When there is only cluster business in the system, that is, cluster dedicated network, all time-frequency resources in the cluster scheduling map can send cluster business.

[0119] When trunking services and normal LTE services coexist in the system, that is, when common LTE public networks support trunking functions, the base station schedules downlink trunking services and downlink LTE common services according t...

Abstract

The invention discloses a method and apparatus for broadcasting cluster system configuration information. The method comprises that a cluster system broadcasts the configuration information of the cluster system, the configuration information including cluster paging channel resource configuration information, and / or cluster random access resource configuration information, and / or cluster scheduling atlas configuration information, and / or cluster cell reselection parameters, and / or cluster adjacent cell information, and / or system support capability indicating information. The invention provides a method and apparatus for effectively broadcasting cluster system configuration in a broadband wireless communication system. By means of the method and the apparatus, the broadcasting of cluster system configuration information can be achieved and a network can be simultaneously compatible with LTE and cluster service.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for broadcasting configuration information of a trunking system. Background technique [0002] In an LTE (Long Term Evolution, Long Term Evolution) system, system information to be broadcast is divided into a master system information block (Master Information Block, MIB for short) and several system information blocks (System Information Block, SIB for short). Among them, the system information block (SIB) has defined multiple types, including: system information block type 1 (SystemInformationBlockType1, referred to as SIB1), system information block type 2 (SystemInformationBlockType2, referred to as SIB2), and so on, LTE Release (version )11 has been defined to System Information Block Type 15 (SystemInformationBlockType15, referred to as SIB15). The MIB contains a limited number of parameters that are most necessary and frequently transmitted, and...
