The embodiment provides a method for broadcasting cluster system configuration information, and specifically adopts the following technical solutions:

Determining cluster system configuration information, including: cluster paging channel resource configuration information, and/or cluster random access resource configuration information, and/or cluster scheduling map configuration information, and/or cluster cell reselection parameters, and/or cluster neighbors Zone information, and/or system support capability indication information.

The implementation of the technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the features in the embodiments and the embodiments of the present application may be arbitrarily combined with each other without conflict. In the public network of the existing LTE terminal and the cluster terminal, the system information that the system needs to deliver includes the system information required by the LTE terminal and the system information required by the cluster terminal. A normal LTE terminal obtains system broadcast parameter information from an existing SIB, and the cluster terminal acquires system broadcast parameter information from an existing SIB and a newly added SIB. The resource configuration information that can be shared by the LTE terminal and the cluster terminal comes from the existing SIB, and the resource configuration information unique to the cluster communication comes from the newly added SIB. The following is a description of specific embodiments.

Embodiment 1

In order to use the LTE channel to transmit the cluster paging message, the cluster user can be paged by the cluster network to implement call setup of the cluster service, and a downlink logical channel cluster paging channel (TPCCH) is added to transmit the cluster paging signaling. The cluster terminal needs to know the resource configuration information of the TPCCH, for example, the TPCCH transmission period and the TPCCH transmission time to obtain the signaling on the TPCCH. The common resource configuration information of the TPCCH includes at least: a TPCCH channel transmission period, and a TPCCH channel subframe transmission time information.

In this embodiment, a new system information block type SIBX is defined, which is used to carry TPCCH resource configuration information. The content of the SIBX is as follows:

TPCCH resource configuration information; The TPCCH resource configuration information includes: a cluster paging channel transmission period, and/or a cluster paging occasion, and/or an identifier of a trunk paging channel (TPCCH-RNTI), and/or resource information of a trunk paging channel. The specific content of the TPCCH resource configuration information may be different according to the specific implementation scheme of the system, including but not limited to the following cases.

If the TPCCH resource is determined by the transmission period and the paging occasion, and the system sets the TPCCH channel identifier to a known fixed value, the TPCCH resource configuration information includes: a cluster paging channel transmission period, and a cluster paging occasion.

The cluster paging channel transmission period refers to the interval at which the paging message is sent, and the UE judges when it is necessary to monitor the paging channel according to the paging period.

The cluster paging occasion includes radio frame and subframe information for transmitting a paging message.

The TPCCH channel identifier refers to the RNTI value of the TPCCH.

If the TPCCH resource is determined by the sending period and the paging occasion, and the system does not set the TPCCH channel identifier to a fixed value, the TPCCH resource configuration information includes: a cluster paging channel sending period, a cluster paging occasion, and a cluster paging channel identifier. .

If the TPCCH resource is determined in other forms, the TPCCH resource configuration information includes: resource information of the cluster paging channel.

Record the SIBX content as SystemInformationBlockTypeX.

The SI message used to carry the SIBX is the SI message specified by the LTE standard protocol. The format of the SI message remains unchanged. The content of the SIBX is filled in the systemInformation-r8 cell of the SI message, as follows:

In the schedulinglnfoList cell of SIB1, the scheduling information and scheduling period of the SI message for sending the SIBX are filled in, and the format is unchanged. The specific contents are as follows: SI scheduling cycle

SIBX SIB type identifier sibTypeX

Where sibTypeX is the SIB type identifier of SIBX, and sibTypeX cannot be duplicated with the existing SIB type identifier.

SIBX transmission process: first determine the cluster control channel resource information; generate SIBX, include cluster control channel resource information in SIBX; load SIBX into SI message; send SI message on BCCH.

Embodiment 2

Random access is the access process of the UE before starting communication with the network. The Physical Layer Random Access Channel (PRACH) is used to transmit random access resources, that is, Random Access Preamble.

The LTE random access process can be divided into two types based on competition (ie, risk of collision) and non-contention based. In the contention-based random access procedure, the UE randomly selects a random access preamble to transmit. Obviously, there is a possibility that multiple UEs send the same preamble, and the eNB will take the conflict resolution process to deal with the problem. In a non-contention based random access procedure, the eNB can avoid collisions by assigning a dedicated preamble to the UE, which is obviously more efficient than a contention based approach, which is for handovers with strict time constraints. A factor that cannot be ignored.

There is a fixed 64 random access preambles for each cell. For the two random access modes that exist, the 64 preamble sequences can be divided into two parts, one for random access based on contention and the other for random access based on non-contention. The serving cell will inform the UE of the contention-based random access preamble number (numberOfRA-Preambles in SIB2) through the system information broadcast, that is, the 64 number of reambles and the numberOf A-Prambles random access preambles are used for contention-based Random access.

The contention-based random access preamble is further divided into two groups (Group A and Group B) to implicitly carry lbit information by selecting which set of preambles, that is, the transmission required to send the third step message (Message3). Information on the total amount of resources. The UE will judge according to the potential size of the message to be sent in the third step. The preamble sequence is selected from the packet, and the system can determine the possible size of the message 3 according to the packet in which the preamble sent by the UE is located, so as to avoid waste of resources by allocating too many uplink resources to the UE. The serving cell will inform the UE of the configuration of the preamble packet by using the system information broadcast: sizeOfRA-PreamblesGroupA( in SIB2) indicates the number of preambles in the GroupA, and the sequence number of the preamble included therein is [0, sizeOf A-PreamblesGroupA - 1 ]. The remaining reamble [sizeOfRA-PreamblesGroupA, numberOfRA-Prambles - 1] are in GroupB.

messageSizeGroupA( in SIB2 ) indicates whether the UE chooses GoupA or GroupB. That is, if the length of Message3 to be sent is less than the threshold, then GroupA is selected, otherwise, GroupB is selected.

messagePowerOffsetGroupB ( in SIB2 ) indicates the offset of the power that selects GroupB to send Message3 (the message is relatively large) relative to the power of the regular size Message3.

maxHARQ-Msg3Tx ( in SIB2 ) indicates the maximum number of times to retransmit Message3.

The random access process of the LTE terminal and the random access process of the cluster terminal are concurrently existed on the public network. To distinguish the random access of the LTE terminal and the random access of the cluster terminal, the cluster terminal needs to be randomly connected. The resources of the incoming process are distinguished from the resources used for the random access procedure of the normal LTE terminal. The division of random resources for normal LTE access and for cluster access can be distinguished over a range of Preamble codes. The 64 random access preambles are divided into three parts: one part is used for LTE terminal based on random access; the other part is used for cluster terminal based on random access; the remaining part is used for non-contention based Random access. According to the LTE protocol, the LTE terminal is configured in the SIB2 based on the contention of the random access resource configuration information, and the first numberOfRA-Prambles (in SIB2) of the 64 preambles starting from the sequence number 0 is used. Therefore, the first numberOfRA-Prambles of the 64 preambles have been occupied by the LTE terminal random access, and the non-contention based random access preamble and the cluster random access preamble are required to be in the remaining (64-numberOf A- Prambles) is allocated in a preamble. The cluster random access resource configuration information is also configured in the system information broadcast. The cluster random access resource configuration information may include: the number of the group random access Preamble, the starting sequence number of the cluster random access Preamble, the number of Preamble used by the cluster for GroupA, and the maximum number of transmissions of the cluster Message3.

In this embodiment, a new system information block type SIBX is defined, which is used to carry a cluster random. Access to public configuration information, the contents of SIBX are as follows:

Cluster random access resource configuration information;

The cluster random access resource configuration information includes one or any combination of the following: a preamble number for the cluster in the contention-based random access preamble, and a preamble start number for the cluster in the contention-based random access preamble. The preamble end number for the cluster in the contention-based random access preamble, the number of GroupA for the cluster based on the contention of the random access preamble, the threshold of the size of the cluster Message3, and the power of the Group3 to send the Message3 relative to The offset of the power of the regular size Message3 and the maximum number of retransmissions of the cluster Message3.

The specific content of the cluster random access resource configuration information varies according to the specific implementation scheme of the system, including but not limited to the following.

If the first half of the remaining (64-numberOfRA-Prambles) preambles are used for cluster random access and the second half is used for non-contention based random access, the cluster random access resource configuration information includes: The number of preambles used for the cluster in the random access preamble.

If the first half of the remaining (64-numberOfRA-Prambles) preambles are used for non-contention based random access and the second half is used for cluster random access, the cluster random access resource configuration information includes: The number of preambles used for the cluster in the random access preamble, and the preamble start number for the cluster in the contention-based random access preamble.

In addition, the base station may also allocate a segment of the remaining (64-numberOfRA-Prambles) preambles to the cluster random access, and the cluster random access resource configuration information includes: a contention-based random access preamble The preamble start number used for the cluster, and the preamble end number used for the cluster in the contention-based random access preamble.

The allocated cluster random access preamble can be further divided into two groups, GroupA and GroupB. To this end, the cluster random access resource configuration information further includes: a preamble number for the cluster in the contention based random access preamble, and/or a preamble start for the cluster in the contention based random access preamble The number, and/or the preamble end number for the cluster in the contention based random access preamble, and the number of GroupA for the cluster based on the contention based random access preamble. For the cluster random access preamble that is assigned GroupA and GroupB, the threshold of the Message3 size that the cluster terminal chooses to use GroupA or GroupB can use the same value as the LTE terminal. That is, the configuration value in SIB2 can also be set differently. At the same time, the offset of the power of the Message3 sent by the cluster GroupB relative to the power of the regular size Message3 can be the same as that of the LTE terminal, that is, the configuration value in the SIB2 can also be set differently. The maximum number of retransmissions of the cluster Message3 can be the same as that of the LTE terminal, that is, the configuration value in the SIB2 is used, and the setting may be different. To this end, the cluster random access resource configuration information includes: a preamble number for the cluster in the contention-based random access preamble, and/or a preamble start number for the cluster in the contention-based random access preamble. And/or based on the preamble end number for the cluster in the contention-based random access preamble, and/or the threshold for the number of GroupA in the contention based on the contention of the random access preamble, and/or the size of the cluster Message3 And/or the offset of the power of Message3 sent by the GroupB to the power of the regular size Message3, and/or the maximum number of retransmissions of the cluster Message3.

Record the SIBX content as SystemInformationBlockTypeX.

Embodiment 3

When the trunking service and the normal LTE service are in the same cell network in the public network environment, the downlink trunking service and the downlink common LTE service need to have concurrent scheduling functions. To this end, the system can divide the resource pool into the time-frequency resources of the scheduling cluster and the time-frequency resources of the scheduled LTE according to the time division or the frequency division. The distribution of the time-frequency resources of the cluster time-frequency resources and the common LTE in one scheduling period The diagram is the scheduling map.

When there is only LTE service in the system, the cluster scheduling map is invalid.

When there is only cluster service in the system, that is, the cluster private network, all time-frequency resources in the cluster scheduling map can send cluster services.

When the cluster service and the common LTE service coexist in the system, that is, when the common LTE public network supports the cluster function, the base station separately schedules the downlink cluster service and the downlink LTE common service according to the predefined time-frequency resource information in the map, and the terminal follows the map. The pre-defined time-frequency resource information respectively receives the downlink cluster service and the downlink LTE normal service. The system tells the terminal to schedule the graphics information through the system information broadcast.

The scheduling map is pre-defined, and the graphic design is given in the form of a sequence number index.

In this embodiment, a new system information block type SIBX is defined, which is used to carry the cluster scheduling map configuration information, and the content of the SIBX is as follows:

{

Cluster scheduling map configuration information;

The cluster scheduling map configuration information is a scheduling graph sequence number, each sequence number represents a map, and the graph information corresponding to the sequence number is predefined, and the map information indicates the time-frequency resource used for the cluster service in a scheduling period. Distribution information of time-frequency resources in LTE services.

Embodiment 4

When the UE completes the cell selection and camps on the corresponding cell, it will routinely search for a better cell according to the cell reselection criteria. If such a cell is found, the UE will select the cell.

To assist the UE in cell reselection in the idle state, the serving cell configures relevant reselection parameter information (SIB3~SIB8) in the system information broadcast. The UE performs the cell reselection process only for the carrier frequency configured in the system information broadcast and having the corresponding priority. The UE determines the candidate cell according to the candidate carrier frequency list configured by the system and the corresponding reselection priority, and then detects whether the cell meets the reselection criterion.

The cluster call setup is completed. During the trunk terminal call, the non-calling user's handover does not require the eNB to participate. Similar to the LTE terminal's idle cell reselection process, it is an autonomous handover. Non-rights To complete the autonomous handover, the user needs to obtain the cell handover related parameters, including the handover threshold configuration parameters, in order to perform the handover decision. The cluster terminal may obtain the cell reselection parameter of the LTE from the existing SIB and complete the autonomous handover according to the LTE cell reselection standard. On the other hand, in order to adapt to the characteristics of the cluster communication, a cluster cell reselection standard different from LTE can also be designed to complete the autonomous handover. For this purpose, the system needs to configure the cluster-specific cell reselection parameters and/or cell handover parameters and broadcast to the cluster terminal. .

The cluster terminal cell reselection process needs to acquire neighboring cell information to determine an alternative cell. The cluster terminal can obtain the neighbor information through the existing SIB of LTE, including the information of the same frequency neighboring area and the inter-frequency neighboring area. On the other hand, in the public network of the existing LTE terminal and the cluster terminal, the neighboring zone carried in the SIB delivered by the system may support the cluster service or the cluster service. Cluster terminal The neighbor information learned from the existing SIB does not indicate whether the neighbor supports the cluster. To do this, you can add cluster neighbor information to the system broadcast.

In this embodiment, a new system information block type SIBX is defined, which is used to carry the cluster cell reselection parameter, the cluster cell handover parameter, the cluster co-frequency neighbor information, and the cluster inter-frequency neighbor information. The content of the SIBX is as follows:

{

Cluster cell reselection parameters;

Cluster cell handover parameters;

Cluster same frequency neighbor information;

Cluster inter-frequency neighbor information;

}

The cluster cell reselection parameter refers to a threshold configuration different from the cluster cell reselection and the normal LTE cell reselection. Record the SIBX content as SystemInformationBlockTypeX.

Embodiment 5

For terminals that support both LTE and cluster functions, whether LTE services or cluster services can be performed depends on the networking conditions of the system, that is, the system support capabilities. The system support capability indication information may be carried in the SIB message, and broadcasted to the terminal through the SI message to let the terminal know.

The cluster system parameter information described in the above embodiments 1 to 5 can be placed in the same SIB according to similar properties. You can define only one SIBX, put all cluster system parameter information as a cell into the SIBX, or define multiple SIBXs, and put the cluster system parameters in the SIBX according to similar properties. The similarity may be as follows: according to the influence range of the parameter, such as which layer of the LTE protocol stack the parameter works; or, according to the role of the parameter, such as radio resource configuration, mobility management, and the like.
