Problems solved by technology

The inventors of this application found that the current LTE system message does not contain cluster information, and if a field is directly added to the existing LTE system message under the 3GPP framework, it may cause compatibility problems, making it impossible for non-cluster terminals to access the cluster network

Embodiment 1

[0068] This embodiment introduces a method for receiving specific service-related system messages, such as figure 1 shown, including the following steps:

[0069] Step 101, user equipment (UE) receives system information through SI-RNTI;

[0070] The UE in this step can be a UE that supports a specific service, or a UE that does not support a specific service. For a UE that does not support a specific service, after receiving the system message, it performs the follow-up process according to the existing technology. For a UE that supports a specific service After receiving the system message, the UE executes step 102.

[0071] The UE receives system messages through the SI-RNTI, including: the UE monitors the PDCCH and determines whether there is an authorization for the SI-RNTI on the PDCCH (that is, whether the CRC of the physical layer signaling on the PDCCH is scrambled with the SI-RNTI). If there is a grant for the SI-RNTI, the UE receives the system message on the phys...

Embodiment 2

[0093] This embodiment introduces a method for sending system messages related to specific services, such as figure 2 shown, including the following steps:

[0094] The network side device broadcasts a system message using the system information radio network temporary identifier (SI-RNTI), and indicates whether the current cell supports a specific service through the content in the system message;

[0095] The network side device broadcasts a system message related to the specific service in a cell supporting the specific service by using a predetermined specific RNTI.

[0096] The aforementioned network side device carries the grant for the SI-RNTI and the grant for a predetermined specific RNTI in the physical downlink control channel (PDCCH), so that the UE can receive it.

[0097] In a preferred embodiment, whether the current cell supports a specific service can be indicated in the following manner: indicate whether the current cell supports a specific service through ...

Embodiment 3

[0106] This embodiment introduces a device for receiving system messages related to specific services. The device is located in a UE supporting specific services, such as image 3 As shown, the device includes a first receiving module 301 and a second receiving module 302, wherein:

[0107] The first receiving module 301 is configured to receive system messages through SI-RNTI;

[0108] Specifically, the first receiving module 301 monitors a physical downlink control channel (PDCCH), determines if there is an authorization for SI-RNTI on the PDCCH, and then receives system information on the physical resource authorized for SI-RNTI. The first receiving module 301 decodes the system message according to the message structure stipulated in the 3GPP protocol.

[0109] The second receiving module 302 is configured to judge whether the current cell supports a specific service through the system message received by the first receiving module 301, and if it is judged that the curren...

Abstract

A transceiving method and device for system information related to a specific service. The receiving method comprises: a user equipment (UE) supporting a specific service receiving a system message through a system information radio network temporary identifier (SI-RNTI) (step 101); and the UE judging whether the current cell supports the specific service through the system message, and if the UE judges that the current cell supports the specific service, receiving the system message related to the specific service (step 102). The transmitting method comprises: a network-side device using an SI-RNTI to broadcast a system message, and indicating whether the current cell supports a specific service through the content of the system message; and the network-side device using a specific predetermined RNTI to broadcast the system message related to the specific service in a cell supporting the specific service.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for sending and receiving system information related to specific services. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, the system information that needs to be broadcast is divided into a master information block (Master Information Block, referred to as MIB) and a system information block (SystemInformation Block, referred to as SIB), and the master information block contains UE The most important information (downlink bandwidth, PHICH (Physical HARQ Indicator Channel) information and SFN (System Frame Number)) required for (user equipment or terminal) access. During transmission, the main information block is transmitted in the BCH (Broadcast Channel, broadcast channel), and its position is fixed; while the SIB is included in the SI message (SystemInformation message) and transmitted in the DL-SCH...
