Description

Method and device for transmitting and receiving specific service related system messages

Technical field

The present invention relates to the field of communications technologies, and in particular, to a method and apparatus for transmitting and receiving information of a specific service-related system.

Background technique

In the LTE (Long Term Evolution) system, the system information to be broadcasted is divided into a Master Information Block (MIB) and a System Information Block (SIB), where the main information block is included. The most important information (downstream bandwidth, PHICH (Physical HARQ Indicator Channel) information, and SFN (System Frame Number)) required by the UE (User Equipment or Terminal) to access. During transmission, the primary information block is transmitted in the BCH (Broadcast Channel), and its location is fixed; and the SIB is included in the SI Message (System Information Message) in the DL-SCH (Downlink Shared Channel). In transit. The mapping relationship between the SIB and the SI message (i.e., in which SI message each SIB is included) is given by the Scheduling Info List in SIB1. Each SIB can only be included in one SI message. If multiple SIBs have the same period, then these SIBs can be included in the same SI message. At the same time, multiple SI messages with the same period can exist at the same time. In SIB, the transmission of SIB1 uses a fixed period with a period of 80 ms and repeats in the 5th subframe of all radio frames satisfying SFN mod 2 =0. Other SI messages are also periodically transmitted in the time domain window (Si-Window). Each SI message has its own SI-Window, and the SI-Window of different SI messages does not overlap. Within a SI-Window, only the corresponding SI messages are transmitted. Within an SI-Window, an SI message can be sent multiple times. The terminal uses the System Information Radio Network Temporary Identifier (SI-RNTI) to receive the PDCCH (Physical Downlink Control Channel) to obtain the resource configuration of the system message, where the value of the SI-RNTI is fixed to FFFF. .

In the LTE-based broadband wireless trunking communication system, in order to implement cluster communication, it is necessary to implement broadcast of cluster system parameters. The inventor of the present application finds that the current LTE system message does not include the cluster information, and if the field is added directly to the LTE existing system message in the 3GPP framework, Can cause compatibility problems, making non-clustered terminals unable to access the cluster network.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

Example 1

This embodiment describes a method for receiving a service-related system message, as shown in FIG. 1, including the following steps:

Step 101: A user equipment (UE) receives a system message by using an SI-RNTI.

The UE in this step may 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, the UE performs the subsequent process according to the existing technology, and supports the specific service. After receiving the system message, the UE performs step 102.

The UE receives the system message by using the SI-RNTI, and the method includes: 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 by the SI-RNTI), If there is an authorization for the SI-RNTI, the UE receives the system message for the physical resource authorized for the SI-RNTI (ie, the physical layer resource scheduled in the PDCCH physical layer signaling scrambled by the SI-RNTI).

Step 102: The UE supporting the specific service determines whether the current cell supports a specific service by using the system message, and if the UE determines that the current cell supports the specific service, receives a system message related to the specific service.

The above specific services (or referred to as scheduled services) include, but are not limited to, trunked communication services.

A method for a UE supporting a specific service to determine whether a current cell supports a specific service by using a system message includes: a UE supporting a specific service passes an IE (Information Element, in a system message) The value of the cell is judged. When the value of the IE satisfies the pre-agreed rule, it is determined that the current cell supports a specific service. The above IE includes but is not limited to one or more of the following IEs:

"csg-Identity" IE in SIB1; "csg-Indication" in IE1; IE; "PLMN-Identity" in SIB1 IE; "in SIB9" hnb-Name (home base station name) "IE.

The pre-agreed rule includes: all or part of the value of the IE is the same as a preset value, where the preset value is a fixed value or a configurable value. The value of the IE is the same as the preset value. It means that the value of the IE part field is the same as the preset value. The part field can be a fixed field or a non-fixed field. A possible case where the preset value is a fixed value is that the fixed value is specified by the protocol. A possible case where the preset value is a configurable value is that the configurable value is previously saved by the UE, but may be configured in the SIM card by other means (for example, non-access stratum signaling or carrier unified configuration in the SIM card) Etc.) Dynamic modification.

If the terminal determines that the current cell supports the specific service and receives a system message related to the specific service, the pre-agreed RNTK is used herein as a Particular SI-RNTI (PSI-RNTI for short), and the PSI-RNTI is dedicated to scheduling specific A special RNTI of the service, which may be the same as or different from the value of the SI-RNTI. (Note: The system message structure scheduled by the PSI-RNTL SI-RNTI when the PSI-RNTI and the SI-RNTI are the same value. The definitions also need to be the same or compatible (and that system messages for specific services are carried by compatibility extensions on the original system message structure). When there are multiple specific services in a cell, different specific services may share one PSI-RNTI, or different specific services may use different PSI-RNTIs. One implementation of PSI-RNTI is: 16 bits long, with a range of [0001, FFFC] (hexadecimal).

In the foregoing step 102, the UE receives the system message related to the specific service by using the PSI-RNTI, including: the UE monitors the PDCCH, and determines whether there is an authorization for the PSI-RNTI on the PDCCH (that is, whether the CRC of the physical layer signaling on the PDCCH is utilized. The PSI-RNTI performs scrambling. If there is authorization for the PSI-RNTI, the UE receives a system message related to the specific service at the physical resource authorized for the PSI-RNTI.

After receiving the system information related to a specific service for the first time, the UE supporting the specific service may periodically receive the system message through the SI-RNTI, and receive the system message related to the specific service through the PSI-RNTI. It can be seen that the UE uses the PSI-RNTI to receive a system related to a specific service. At the same time, the SI-RNTI can still receive system messages, and the reception of messages of different service systems does not affect each other, effectively avoiding the occurrence of compatibility problems.

A system message related to a specific service may be composed of one or more specific system information blocks (for example, PSIB1, PSIB2, PSIB3, PSIB4, etc.); or may be composed of one or more SIBs, which may include existing used SIB (such as SIB2, SIB3, etc.) or including reserved SIBs (such as SIB19, SIB20, etc.). For the case of using multiple specific system information blocks:

A method for receiving a system message related to a specific service is: the UE first receives the PSIB1 in a transmission period of the PSIB1, and acquires scheduling information of other specific system information blocks from the PSIB1 (in addition to the scheduling information, the PSIB1 may carry other specifics. Business related information), according to the obtained scheduling information to obtain other specific system information blocks.

Among them, the transmission of PSIB1 uses a fixed period and repeats in a subframe that satisfies certain conditions. For example: A certain condition may be: SFN mod 8 = the 5th subframe of the radio frame of X, where X is a predetermined value, and may be an integer between 0 and 7. After reading the PSIB1, the UE acquires other information blocks according to the scheduling information therein.

Another way to receive system messages related to a specific service is: PSIB2 or PIB3 or PSIB4 is also transmitted in a fixed transmission time mode similar to PSIB1, that is, the UE receives each specific system in a transmission cycle corresponding to each specific system information block. Information block, at this time, PSIB1 no longer carries scheduling information, but system information related to a specific service.

For the case of using SIB: The transmission of SIB messages still uses the existing transmission mechanism.

The system message scheduled by the SI-RNTI and the system message related to the specific service scheduled by the PSI-RNTI may have the same or different message structure definitions (ie, different ASN.1 codecs), specifically, After the SI-RNTI receives the system message, the UE performs decoding according to the message structure specified by the 3GPP protocol (defined according to the ASN.1 message structure). After receiving the system message related to the specific service through the PSI-RNTI, the UE performs codec according to the message structure of the specific service definition. The message structure of a specific service definition may be identical to, identical to, or completely different from the message structure defined by the 3GPP.

In a preferred embodiment, after determining that the current cell supports a specific service, the UE may further enter a Steps use the content in the system information to determine whether they have the right to use the specific service of the current cell. The UE may first determine whether it has the right to use the specific service of the current cell. When the UE determines that it has the right to use the specific service of the current cell, the UE may receive the system information related to the specific service. Alternatively, the UE may also receive the specific service related information. System information, and then determine whether they have access to the specific business of the current cell.

Specifically, the system message may be used to determine whether the current cell-specific service IE is used to determine whether the value of the IE satisfies the pre-agreed rule. This includes but is not limited to one or more of the following IEs:

"csg-Identity" IE in SIB1; "csg-Indication" IE in SIB1; "PLMN-Identity" IE in SIB1; "hnb-Name" IE in SIB9.

The pre-agreed rules are the same as above, and include: all or part of the value of the IE is the same as the preset value, where the preset value is a fixed value or a configurable value.

Here, it is judged whether the UE has the right to use the IE range used by the current cell-specific service, and is the same as the IE range used to determine whether the current cell supports a specific service. Preferably, the two judgments select different IEs and/or rules.

Example 2

The above system messages related to a specific service are composed of one or more PSIBs; or, the system messages related to a specific service are composed of one or more SIBs. When a system message related to a specific service includes a plurality of PSIBs, the network side device broadcasts a system message related to a specific service in a cell supporting a specific service using a predetermined specific RNTI in one of the following ways:

In a first mode, the network side device uses a transmission resource (a resource indicated by the PDSCH in the PDCCH) used by the specific system information block authorized by the specific RNTI in the PDCCH supporting the cell of the specific service, where the first specific system information block is fixed. a transmission period transmission, where the first specific system information block includes scheduling information of other specific system information blocks;

The transmission period of the first specific system information block is a fixed subframe in the radio frame that satisfies the predetermined condition. For example, the predetermined condition is: SFN mod 8 = X, where X is an integer between 0 and 7, and the fixed subframe is the fifth subframe.

Manner 2: The network side device uses a transmission resource used by a specific system information block authorized by a specific RNTI in a PDCCH supporting a specific service cell, and the plurality of specific system information blocks are transmitted by using a fixed transmission period, where the multiple The transmission period of a particular system information block is the same or different.

In a preferred embodiment, the network side device may also indicate, by the content in the system message, whether the UE has the right to use the specific service of the current cell. Specifically, the UE may be instructed to use the specific service of the current cell by using the value of the IE in the system message, and set the IE in the system message block sent to the UE when the UE is entitled to use the specific service of the current cell. The value meets the pre-agreed rules. For the value range and rules of IE, refer to the related description in Embodiment 1.

The message structure of the system message sent by the first sending module 401 can use the message structure specified by the 3GPP protocol; the message structure of the second sending module 402 sending the system message related to the specific service can use the message structure defined by the specific service, the specific service The defined message structure is identical, partially identical or completely different from the message structure specified by the 3GPP protocol.

System messages related to a specific service may consist of one or more SIBs, or one Or a plurality of PSIB components; if composed of a plurality of PSIBs, the second sending module 402 can broadcast system messages related to the specific service in one of the following ways:

In a first mode, the second sending module 402 uses the transmission resource used by the specific system information block authorized by the specific RNTI in the PDCCH supporting the cell of the specific service, where the first specific system information block is transmitted by using a fixed transmission period, the first specific The system information block contains scheduling information of other specific system information blocks; or

Preferably, the transmission period of the first specific system information block is a fixed subframe in a radio frame that satisfies a predetermined condition. For example, the fifth subframe in the radio frame satisfying SFN mod 8 = X, where X is an integer between 0 and 7.

In the second mode, the second sending module 402 uses the transmission resource used by the specific system information block authorized by the specific RNTI in the PDCCH supporting the cell of the specific service, and the plurality of specific system information blocks are transmitted by using a fixed transmission period, and multiple The transmission period of a particular system information block is the same or different.

In a preferred embodiment, the first sending module 401 is further configured to indicate, by using the content in the system message, whether the UE is authorized to use the specific service of the current cell. Specifically, the first sending module 401 can indicate whether the UE is entitled to use the specific service of the current cell by using the value of the IE in the system message. When the UE is entitled to use the specific service of the current cell, the first sending module 401 sets the direction. The value of the IE in the system message block sent by the UE meets a pre-agreed rule. The scope and rules of the IE are described in Embodiment 1.

The receiving apparatus of the above embodiment 3 and the transmitting apparatus of the fourth embodiment can be combined into one transmitting and receiving system.

The following describes the method of the foregoing embodiment by taking a specific service as a cluster service as an example.

Application example 1

As shown in Figure 5, the following steps are included:

Step 501: The UE uses the SI-RNTI to receive the system message in the cell, and the system information is used.

Coding in the manner specified by the 3GPP protocol;

Step 502: After reading the system message, the UE determines whether the value of the IE "hnb-Name" in the SIB9 is "cluster network", and whether the IE "csg-Identity" in the SIB1 is included in the UE. In the saved white list "whitelist", if the UE satisfies the above two conditions, and performs step 503, if any of the conditions are not satisfied, the UE does not use the PSI-RNTI to read the cluster service related system information; Step 503: The UE considers this The cell supports the cluster service and starts to receive the cluster related system message by using the PSI-RNTI (which is a value of FFF0);

In this example, the system message received by the UE using the PSI-RNTI is different from the system message structure received by the SI-RNTI, so the UE performs ASN.1 codec on the messages received on different RNTIs by using different decoding functions.

When judging the value of the IE "hnb-Name" in SIB9, the possible ways are as follows: Determine whether the information corresponding to the first 8 bytes in the "hnb-Name" string is "cluster network"; judge "hnb-Name" Whether the string contains "cluster network" 4 words;

The system information block related to the cluster service includes PISB1, PSIB2, and PSIB3, wherein the transmission of the PSIB1 is fixed for a fixed period of 80 ms, and is repeated in the fifth subframe of the radio frame satisfying the SFN mod 8 =1. The scheduling information of the PSIB2 and PSIB3 system information blocks may be included in the PSIB1. After reading the PSIB1, the UE acquires the PSIB2 and the PSIB3 according to the scheduling information therein; or, the PSIB2 and the PSIB3 may also use the fixed transmission timing similar to the PSIB1. the way.

The IE used in the system message to determine whether to support a specific service may also be a combination of one or more of the following IEs:

IE "csg-Identity" in SIB1;

IE "csg-Indication" in SIB1;

IE "PLMN-Identity" in SIB1;

IE "hnb-Name" in SIB9;

Among them, the rules agreed in advance include but are not limited to one or a combination of the following:

The value of IE is a special value agreed in advance;

The value of a part of the field in the IE is a special value agreed in advance, or the IE contains a special field; the value of the IE matches the information locally saved by the UE.

Application example 2 As shown in Figure 6, the following steps are included:

Step 601: The UE receives the system message by using the SI-RNTI in the cell, where the system information is encoded by using a method specified by the 3GPP protocol.

Step 602: After reading the system message, the UE determines whether the "PLMN-Identity" carried in the SIB 1 meets the pre-agreed value condition (for example, all 0s, all 1s, or a predetermined special value, etc.) If not satisfied, the UE considers that the cell does not support the cluster service, and performs step 604, if the step 603 is satisfied;

Step 603: If the UE determines that the system message satisfies the foregoing condition, the UE determines that the cell supports the cluster service, and further determines whether the value of the IE "csg-Indication" in the SIB1 is "true" (True); if the value is "True" " , then step 605 is performed, otherwise step 604 is performed;

Step 604: The UE does not use the PSI-RNTI to read cluster service related system information.

Step 605, further determining whether the IE "csg-Identity" is included in the white list "whitelist" saved by the UE. If not, the UE considers that it does not have the right to use the cluster service of the cell, and performs step 604; if included, enters Step 606;

Step 606: The UE considers that it has the right to use the cluster service of the cell and starts to use the SI-RNTI to receive the cluster-related system message (that is, the value of the PSI-RNTI is the same as the value of the SI-RNTI).

When acquiring the cluster system message by using the SI-RNTI, the UE first acquires the PSIB1 at a fixed time point (the transmission time of the PSIB1 is previously agreed by the standard, and the fixed period is 80 ms, and the fifth of the radio frames satisfying the SFN mod 8 =1 The subframes are repeated; and the system information blocks such as PSIB2 and PSIB3 are obtained according to the scheduling information in PSIB1.

Note: At this time, the network side needs to ensure that the scheduling time of the PSIB and the traditional SIB does not overlap.

Note: The system message received by the UE using the PSI-RNTI is different from the system message structure received by the SI-RNTI. Therefore, the UE uses different decoding functions to perform ASN.1 encoding and decoding on messages received on different RNTIs.

Note: The UE determines whether it has the right to use the cell and the UE through the "csg-Identity" and the "csg-Indication" to determine whether the cell supports the cluster service. The UE may first determine whether it has the right to use the cell. Then, it is determined whether the cell supports the cluster service, and then listens to the PSI-RNTI to obtain the cluster system message when both are satisfied. Among them, the system information block related to the cluster service includes PISB1 and PSIB2. The transmission of PSIB1 is fixed for a period of 80 ms, and is repeated in the fifth subframe of the radio frame satisfying SFN mod 8 =1. PSIB2 also uses a fixed period of 80 ms and repeats in the 5th subframe of the radio frame satisfying SFN mod 8 = 3.

The IE used in the system message to determine whether to support a specific service is not limited to

"PLMN-Identity" can also be a combination of one or more of the following IEs:

IE "csg-Identity" in SIB1;

IE "sgg-Indication in SIB1;

IE "PLMN-Identity" in SIB1;

IE "hnb-Name" in SIB9;

The value of IE is a special value agreed in advance;

Application example 3

As shown in Figure 7, the following steps are included:

Step 701: The UE receives the system message block 1 (SIB1) in the cell by using the SI-RNTI, and the system information is encoded in a manner specified by the 3GPP protocol.

Step 702: After reading the system message block 1 (SIB1), the UE determines the "csg- carried in the SIB1.

Whether the value in "Indication" is "True", if the value is "True", then go to step 703, otherwise execute 704;

Step 703, further determining whether the IE "csg-Identity" is included in the white list "whitelist" saved by the UE, if not, the UE considers that the cell does not support the cluster service, and performs step 704; if included, according to the white list If the information is that the cell supports the cluster service, step 705 is performed. Step 704: The UE does not use the PSI-RNTI to read the cluster service related system information.

Step 705: The UE uses the SI-RNTI (that is, the value of the PSI-RNTI is the same as the value of the SI-RNTI) or The PSI-RNTK is different from the SI-RNTI value, and receives a cluster-related system message, where the cluster-related system message can be carried by an existing SIB message (such as SIB2, SIB3, etc.) or used. The reserved SIB carries (such as SIB19, SIB20, etc.), wherein the transmission of the SIB message follows the existing transmission mechanism.

Among them, the IE used in the system message to determine whether to support a specific service is not limited to "csg-

Indication" and "csg-Identity" can also be a combination of one or more of the following IEs:

IE "csg-Identity" in SIB1;

IE "csg-Indication" in SIB1;

IE "PLMN-Identity" in SIB1;

IE "hnb-Name" in SIB9;

The value of IE is a special value agreed in advance;

Application example 4

As shown in Figure 8, the following steps are included:

Step 801: The UE uses the SI-RNTI to receive the system message block 1 (SIB1) in the cell, and the system information is encoded in a manner specified by the 3GPP protocol.

Step 802: After reading the system message block 1 (SIB1), the UE determines the information carried in the SIB1.

Whether the "PLMN-Identity" meets the pre-agreed value conditions (for example, all 0s, all 1s, or a special value specified in advance). If the UE determines that the system message cannot meet the above conditions, the UE considers that the cell is not Supporting the cluster service, performing step 803; if the UE determines that the system message satisfies the above condition, the UE determines that the cell supports the cluster service, and performs step 804;

Step 803: The UE does not use the PSI-RNTI to read the cluster service related system information.

Step 804, further determining whether the IE "csg-Identity" is included in the white list "whitelist" saved by the UE. If not, the UE considers that the UE does not have the right to use the cluster service of the cell. Step 803; if yes, proceed to step 805;

Note: The UE uses "csg-Identity" and "csg-Indication" to determine whether it is authorized to use the cell and the UE to determine whether the cell supports cluster services without a clear sequence.

The above step 804 is optional, and the process proceeds directly to step 805 from step 803.

Step 805: The UE receives the cluster-related system message by using the SI-RNTI (that is, the value of the PSI-RNTI is the same as the value of the SI-RNTI) or the PSI-RNTI (that is, the value of the PSI-RNTI is different from the value of the SI-RNTI).
