Description

Method for receiving service, method and device for sending service

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method for receiving a service, a method for sending a service, and an apparatus for sending a service.

Background

The narrowband Internet of Things (NB-IoT) working phase (Work Item, WI) is passed and started in the 3GPP Release 13(Release 13) phase. The goal of the WI phase of the narrowband Internet of Things is to standardize the wireless access of the Cellular Internet of Things (CIoT). The technology is extended based on Long Term Evolution (LTE)/LTE evolution (LTE-a), and the network characteristics/goals mainly considered are: the indoor coverage is enhanced, the access of a large number of low-speed devices is supported, the delay sensitivity is low, the device cost is reduced, the device power consumption is reduced, the network architecture is optimized, and the like.

Some of the characteristics that may exist for currently recognized narrowband internet of things (NB-IoT) communications are:

NB-IoT terminals have low mobility;

the data transmission between the NB-IoT terminal and the network side has low real-time requirement on the data transmission;

NB-IoT terminals are energy limited, requiring extremely low power consumption;

only small data volume information transmission is carried out between the NB-IoT terminal and the network side;

NB-IoT terminals have low implementation complexity, and so on.

An actual NB-IoT terminal may have one or more of the characteristics described above.

To mitigate cell loading, NB-IoT supports multi-carrier operation. Under multi-carrier operation, the carriers are divided into a main (anchor) carrier and a non-anchor carrier. The terminal on the anchor carrier can receive NPBCH (narrowband physical broadcast channel)/NPSS (narrowband primary synchronization signal), NSSS (narrowband secondary synchronization signal) and SIB (in-band signaling) transmission, and the R13 terminal on the non-anchor carrier currently only expects NB-PDCCH (narrowband physical downlink control channel)/NB-PDSCH (narrowband physical downlink shared channel) and/or NB-PUSCH (narrowband physical uplink shared channel) transmission.

NB-IoT terminals cannot operate on multiple carriers simultaneously due to limited capabilities. In R13, random access can only be initiated on an anchor carrier, and when a connected UE is configured as a non-anchor carrier, the UE will subsequently operate on the non-anchor carrier until entering an idle state, or it is necessary to initiate random access in a connected state, or it is allocated to another carrier.

Idle UEs in R13 only support camping on an anchor carrier, and subsequent enhancements may allow receiving pages or even camping on a non-anchor carrier.

In LTE, Multicast services can be transmitted in MBMS (Multimedia Broadcast/Multicast Service) and SC-PTM (Single Cell Point To Multicast) modes.

In the MBMS mode, all cells participating in MBMS in a certain MBSFN (Multimedia Broadcast multicast service Single Frequency Network) area transmit the same content on the same time and Frequency domain resources. The logical channels of the MBMS include an MCCH (Multicast Control Channel) and an MTCH (Multicast Traffic Channel). The MBSFN area identity and the corresponding MCCH configuration information are broadcasted in SIB 13. The MCCH signaling carries the ongoing MBMS service information of the current cell and the corresponding radio resource configuration. And the UE receives the MBMS transmitted on the MTCH by receiving the MCCH. MCCH message update is similar to the concept of a system message modification period, and the MCCH can be updated only at the boundary of the MCCH modification period. And the MCCH message updating indication is notified through the PDCCH scrambled by the M-RNTI.

In the SC-PTM mode, multicast service is transmitted in a single cell, and a base station is responsible for scheduling. The base station can flexibly schedule the transmission of multicast service and unicast service on a certain cell. The logical channels of the SC-PTM include an SC-MCCH (Single Cell multicast Control Channel) and an SC-MTCH (Single Cell multicast transport Channel). SC-MCCH and SC-MTCH are transmitted on DL-SCH, UE obtains specific scheduling information on corresponding DL-SCH through PDCCH scrambled based on specific RNTI (RNTI corresponding to SC-MCCH is SC-RNTI which is a fixed value, RNTI corresponding to SC-MTCH is G-RNTI, each MBMS corresponds to G-RNTI one by one and is configured in SC-MCCH). The SIB20 broadcasts configuration information of the SC-MCCH. The SC-MCCH provides the MBMS service information and corresponding scheduling information of the current cell, the SC-PTM condition provided by the adjacent cell and the like. The modification period concept is also used when updating SC-MCCH as well as MCCH. And the SC-MCCH updating indication is notified through the PDCCH scrambled by the SC-N-RNTI. And after the UE receives the SC-MCCH updating indication, receiving the updated SC-MCCH in the same subframe.

NB-IoT supports multi-carrier operation, but NB-IoT terminals can only operate on one carrier at the same time. If the multicast service is transmitted only on the anchor carrier, and the UE is currently operating or camping on a non-anchor carrier, how the terminal receives the multicast service at this time has not been studied yet.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, a first embodiment of the present invention provides a method for receiving a service, which is applied to a terminal side, and includes:

step 11, receiving the configuration of the network side, and enabling the terminal to work on the auxiliary carrier configured by the network side;

step 12, reporting the identifier of the preset multicast service which is interested by the terminal to the network side so that the network side can acquire the information of the preset multicast service which is interested by the terminal;

step 13, receiving first indication information sent by a network side according to the information of the preset multicast service which is interested by the terminal, and switching to a preset main carrier wave which is configured in advance according to the indication of the first indication information to receive the preset multicast service which is interested by the terminal; or, step 14, receiving the data information of the preset multicast service, which is sent by the network side in a unicast manner, on the secondary carrier configured by the network side.

Accordingly, as shown in fig. 2, a second embodiment of the present invention provides a method for sending a service, which is applied to a network side, and includes:

step 21, configuring an auxiliary carrier for the terminal so that the terminal works on the auxiliary carrier;

step 22, receiving an identifier of a preset multicast service which is reported by a terminal and is interesting to the terminal, and acquiring information of the preset multicast service which is interesting to the terminal according to the identifier of the preset multicast service;

step 23, sending first indication information for indicating that the terminal is switched to a preset main carrier wave configured in advance to receive the preset multicast service which the terminal is interested in to the terminal according to the information of the preset multicast service; or, step 24, sending the data information of the preset multicast service, which is interested by the terminal, to the terminal in a unicast manner on the secondary carrier.

In the above embodiments of the present invention, the narrowband internet of things supports multi-carrier operation; and under the multi-carrier operation, the carriers are divided into a main carrier (anchor carrier) and a non-anchor carrier (non-anchor carrier). The terminal can work on the pre-configured main carrier after accessing the network, and when the network side configures the auxiliary carrier for the terminal, the terminal is switched to the auxiliary carrier so as to work in the auxiliary carrier. It should be noted that, in the process that the terminal operates on the secondary carrier, if the network side cancels the configuration of the secondary carrier, the terminal returns to the primary carrier to operate or reside.

Specifically, the preset multicast service that the terminal is interested in may be understood as a preset multicast service that the terminal needs to receive or a preset multicast service that the terminal wants to receive.

In the above embodiment of the present invention, the terminal working on the secondary carrier reports the multicast service that the terminal is interested in to the network, and during the transmission of the multicast service that the terminal perceives, no other service data is transmitted on the secondary carrier, so before the service starts or when the service has started but has not ended, the terminal switches from the secondary carrier to the primary carrier according to the indication of the network side, and receives the multicast service on the primary carrier; or the data information of the preset multicast service sent in a unicast mode is directly received on the auxiliary carrier, so that the multicast service is received by the terminal working or residing on the auxiliary carrier.

Further, in the first embodiment of the present invention, since the terminal is switched to the primary carrier in step 13 to receive the preset multicast service, after the specific step 13, the method provided in the first embodiment of the present invention further includes:

Accordingly, after step 23 in the second embodiment of the present invention, the method provided in the second embodiment of the present invention further includes:

Namely, after the service is finished, switching back to the auxiliary carrier according to the indication of the network side; the terminal in the method for receiving the service can dynamically switch between the main carrier and the auxiliary carrier to receive the multicast service, thereby not only realizing the flexibility of service reception, but also improving the effective utilization rate of network infinite resources.

Further, in the foregoing embodiment of the present invention, the terminal may or may not have a unicast service that needs to be transmitted on the secondary carrier within the transmission time period of the preset multicast service that is interested in.

Specifically, for a case where there is a unicast service to be transmitted on an auxiliary carrier, the embodiment of the present invention provides two processing manners:

in a first mode, step 13 in the first embodiment of the present invention includes:

step 131, if the terminal has a unicast service to be transmitted on an auxiliary carrier configured on the network side within the transmission time period of the preset multicast service that the terminal is interested in, switching to a preset main carrier configured in advance according to the indication of the first indication information to receive the preset multicast service that the terminal is interested in and receiving the unicast service to be transmitted on the auxiliary carrier on the main carrier.

Accordingly, in the second embodiment of the present invention, step 23 includes:

step 231, if the network side finds that there is a unicast service to be transmitted on the secondary carrier within the transmission time period of the preset multicast service in which the terminal is interested, sending, to the terminal, first indication information for indicating that the terminal switches to a pre-configured primary carrier to receive the preset multicast service in which the terminal is interested and indicating that the terminal receives the unicast service to be transmitted on the secondary carrier on the primary carrier according to the information of the preset multicast service.

In this way, when a network side (base station) finds that a terminal is interested in a preset multicast service transmission time period, the terminal has service data transmission on an auxiliary carrier configured on the network side, but the network side still decides to convert the terminal to a main carrier to receive the multicast service; when receiving the multicast service which the terminal is interested in on the main carrier, the network side (base station) sends the unicast service which is originally required to be transmitted on the auxiliary carrier to the terminal on the main carrier in a unicast mode; that is, the terminal receives the preset multicast service on the terminal main carrier within the transmission time period of the preset multicast service, and at the same time, the terminal also transmits other service data (service data that originally needs to be transmitted within the transmission time period of the preset multicast service) on the terminal main carrier.

In a second mode, step 14 in the first embodiment of the present invention includes:

step 141, if the terminal has a unicast service to be transmitted on an auxiliary carrier configured on the network side in a transmission time period of a preset multicast service in which the terminal is interested, the terminal receives data information of the preset multicast service sent by the network side in a unicast manner on the auxiliary carrier configured on the network side in the transmission time period of the preset multicast service and receives the unicast service to be transmitted on the auxiliary carrier.

Accordingly, step 24 in the second embodiment of the present invention comprises:

step 241, if the network side finds that there is a unicast service to be transmitted on the auxiliary carrier within the transmission time period of the preset multicast service in which the terminal is interested, sending the data information of the preset multicast service in which the terminal is interested to the terminal on the auxiliary carrier in a unicast manner, and sending the unicast service to be transmitted on the auxiliary carrier to the terminal on the auxiliary carrier.

That is, when the network side finds that the terminal has service data transmission on the secondary carrier configured on the network side in the transmission time period of the preset multicast service in which the terminal is interested, the network side decides not to convert the terminal to the primary carrier to receive the multicast service

In this way, when a network side (base station) finds that a terminal is interested in a preset multicast service transmission time period, the terminal transmits service data on an auxiliary carrier configured on the network side, so that the network side decides not to convert the terminal to a main carrier to receive the multicast service; after the multicast service which the terminal is interested in starts to be transmitted, the network side (base station) schedules the data information of the preset multicast service in a unicast mode and sends the data information to the terminal; that is, the terminal receives the data information of the preset multicast service, which is sent by the network side in a unicast manner, on the auxiliary carrier configured on the network side in the transmission time period of the preset multicast service, and at the same time, the terminal also transmits other service data (service data which needs to be transmitted in the transmission time period of the preset multicast service originally) on the auxiliary carrier.

For the case that there is no unicast service to be transmitted on the secondary carrier, the present invention provides a processing method, where step 13 in the first embodiment of the present invention includes:

step 132, if there is no unicast service to be transmitted by the terminal on the secondary carrier configured on the network side within the transmission time period of the preset multicast service that the terminal is interested in, switching to the preset multicast service that the terminal is interested in on the pre-configured primary carrier according to the indication of the first indication information.

step 232, if the network side does not find that there is a unicast service to be transmitted on the secondary carrier within the transmission time period of the preset multicast service that the terminal is interested in, sending first indication information for indicating that the terminal switches to a pre-configured primary carrier to receive the preset multicast service that the terminal is interested in to the terminal according to the information of the preset multicast service.

In this way, when the network side (base station) finds that the terminal is interested in a preset multicast service transmission time period, the terminal does not transmit service data on the secondary carrier configured on the network side, so that the network side decides to convert the terminal to the primary carrier to receive the multicast service without considering the reception or transmission of other service data.

Further, in the first embodiment of the present invention, the method includes, before step 12:

step 121, acquiring information of one or more multicast services according to a configuration file of the multicast services acquired in advance;

and step 122, selecting a preset multicast service which is interested by the terminal from the one or more multicast services.

Specifically, the terminal acquires information of one or more multicast services supported by the network based on a configuration file of the multicast service acquired in advance, finds a service in which the terminal is interested, and reports an identifier of the service in which the terminal is interested to the network side, and the network side can determine a start time and an end time of a preset multicast service in which the terminal is interested according to the identifier of the multicast service in which the terminal is interested and the configuration file of the multicast service.

Specifically, the information of the multicast service includes an identifier of the multicast service, a service area of the multicast service, a start time of the multicast service, and an end time of the multicast service.

Accordingly, in a second embodiment of the present invention, step 22 comprises:

And the information of the preset multicast service comprises an identifier of the preset multicast service, a service area of the preset multicast service, the starting time of the preset multicast service and the ending time of the preset multicast service.

Further, the transmission timing of the first indication information and the content of the first indication information in the above embodiment of the present invention are described in two cases, which are respectively: the current system time is positioned before the starting time of the preset multicast service; and the current system time is positioned between the starting time and the ending time of the preset multicast service.

In the first case: the current system time is positioned before the starting time of the preset multicast service; step 13 in the first embodiment of the present invention comprises:

step 133, if the current system time is before the starting time of the preset multicast service, receiving first indication information sent by the network side before the starting time of the preset multicast service;

step 134, according to the indication of the first indication information, switching from the starting time of the preset multicast service to a preset multicast service that is interested by the receiving terminal on a pre-configured main carrier; and the starting time of the preset multicast service is determined by the network side according to the information of the preset multicast service which is interested by the terminal.

Accordingly, step 23 in the second embodiment of the present invention comprises:

step 233, determining the starting time of the preset multicast service in which the terminal is interested according to the information of the preset multicast service;

step 234, if the current system time is before the starting time of the preset multicast service, sending a first indication message to the terminal before the starting time of the preset multicast service; the first indication information is used for indicating the terminal to switch from the starting time of the preset multicast service to a preset multicast service which is configured in advance and is interested by the receiving terminal on a main carrier.

That is, the network side instructs the terminal to switch to the primary carrier to receive the service of interest before the service starts.

In the second case: the current system time is located between the starting time and the ending time of the preset multicast service, namely the service is started but not ended; step 13 in the first embodiment of the present invention comprises:

step 135, if the current system time is between the starting time and the ending time of the preset multicast service, receiving first indication information sent by a network side at the current system time;

step 136, switching from the current system time to a preset multicast service which is of interest to a receiving terminal on a pre-configured main carrier according to the indication of the first indication information; and the starting time and the ending time of the preset multicast service are determined by the network side according to the information of the preset multicast service which is interested by the terminal.

step 235, determining the starting time and the ending time of the preset multicast service which is interested by the terminal according to the information of the preset multicast service;

step 236, if the current system time is between the starting time and the ending time of the preset multicast service, sending a first indication message to the terminal at the current system time; the first indication information is used for indicating the terminal to switch to a preset multicast service which is in the interest of the terminal on a pre-configured main carrier from the current system moment.

That is, the terminal is instructed to switch to the primary carrier from the current time to receive the service of interest.

Further, in the above embodiment of the present invention, the step of receiving the multicast service of interest on the primary carrier in the above two cases (i.e. step 13) includes:

After receiving the first indication information of the base station, the terminal switches the radio frequency transceiver to the main carrier to receive a multicast control channel (MCCH or SC-MCCH) to acquire service configuration information, and then receives data information of a preset multicast service, which is transmitted on a multicast service channel (MTCH or SC-MTCH), on the main carrier based on the service configuration information, where the preset multicast service is of interest to the terminal.

Preferably, in the above embodiments of the present invention, the terminal receives the first indication information and/or the second indication information by receiving radio resource control signaling (i.e. dedicated RRC signaling). Namely, the network side sends the first indication information and/or the second indication information to the terminal through dedicated RRC signaling.

step 53, the network side knows the start and stop time of the service in which the terminal is interested based on the service configuration file;

step 54, the network side finds that the terminal has other service data in the non-anchor carrier wave for transmission, so that the terminal is not determined to be switched to the anchor carrier wave;

step 65, after receiving the indication from the network side, the terminal switches the radio frequency transceiver to an anchor carrier to receive a (SC) -MCCH channel to acquire service channel configuration information, and then receives service data transmitted on a (SC-) MTCH channel based on the configuration information; meanwhile, the terminal also receives other service data which needs to be transmitted in the non-anchor carrier at the anchor carrier;
