Description
[ technical field ] A method for producing a semiconductor device
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for transmitting identification information.
[ background of the invention ]
Multefire (mf) is a radio access technology that extends LTE (Long Term Evolution) to an unlicensed frequency band. In view of the problems of fairly occupying unlicensed band channels and avoiding mutual interference between devices, the MF system introduces a Listen Before Talk (LBT) mechanism, and signals are transmitted only when LBT succeeds. An enhanced Machine Type Communication technology is introduced into the MF system to improve transmission efficiency of data signals, broadcast signals, or other information, and the MF system introduced with the enhanced Machine Type Communication (eMTC) technology may also be referred to as an eMTC-MF system. The signaling procedure of the eMTC-MF system includes anchor channel transmission and data channel transmission, and the entire signaling period is long due to the limitation of LBT mechanism and the repeated transmission of signals.
In the prior art, when a terminal accesses a network, identification information related to the network needs to be acquired to determine whether the terminal is a neutral host and an operator network supported by the terminal. For MF systems that do not introduce eMTC, the network device may carry identification information in a system message of the downlink data signal to send the identification information to the terminal. However, currently, there is no feasible method for transmitting the identification information for the eMTC-MF system.

The embodiment of the invention provides a transmission method of identification information, which is applied to an unauthorized frequency band Communication system (especially a cellular Communication system independently working in an unauthorized frequency band, such as an enhanced Machine Type Communication (eMTC) -MF) introducing eMTC) introducing an enhanced Machine Type Communication technology (eMTC), and in the transmission process of the identification information between a terminal and network equipment.
The mobile communication technology of the present invention may be WCDMA (Wideband Code Division Multiple Access), CDMA2000(Code Division Multiple Access 2000), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access), WiMAX (world wide Interoperability for Microwave Access), LTE/LTE-a (Long Term Evolution/Long Term Evolution-Advanced, Long Term Evolution/enhanced Long Term Evolution), LAA (localized-Assisted Access, radio Access based on authorized frequency band), multimedia, and fifth, sixth, and nth generation mobile communication technologies that may occur subsequently.
For convenience of description, the following embodiments are illustrated using an eMTC-MF system. MulteFire is a radio access technology that extends LTE to unlicensed bands, in which unlicensed band carriers can independently provide services without the help of licensed band carriers. This technology also becomes stand-alone LTE-U (stand-alone LTE-U). In order to fairly occupy the unlicensed band channel and avoid mutual interference between unlicensed band devices and other devices in the unlicensed band (e.g., WiFi devices), the MF physical layer introduces a Listen-Before-Talk (LBT) mechanism similar to the WiFi carrier sensing technique. When the network device or the terminal monitors that the unlicensed frequency band channel is occupied, namely, the LBT fails, the signal transmission is stopped, and when the channel is monitored to be idle, namely, the LBT succeeds, the signal is transmitted. In the MF system, in order to better support the internet of things service, an enhanced machine-type communication technology is introduced into an unlicensed frequency band, which is called an eMTC-MF system in the embodiment of the present invention.
Specifically, the network device refers to a form of a radio station, and refers to a radio Access network device that sends various messages to a terminal through a mobile communication switching center in a certain radio coverage area, and the network device may include a base station, an Access Point (AP), and the like.
The terminal refers to a terminal side product capable of supporting a communication protocol of a land mobile communication system, and a special communication Modem module (Wireless Modem) can be integrated by various terminal forms such as a mobile phone, a tablet computer, a data card and the like so as to complete a communication function.
The Identification information refers to a Neutral Host network Identification (NHN-ID) of the Neutral Host network and/or a provider Identification (PSP-ID) of the Participating service. And the terminal acquires the identification information sent by the network equipment and accesses the network when the identification information supported by the terminal is confirmed. Specifically, the terminal determines whether the host network is a neutral host network supported by the terminal according to the NHN-ID so as to complete cell selection/reselection; and determining whether the carrier is a self-supported carrier according to the PSP-ID so as to access the carrier network.
It should be noted that the number of NHN-IDs in a neutral host network is one, the number of PSP-IDs is M, and M is an integer greater than or equal to 1.
As shown in fig. 1, the method includes:
101. the network equipment sends the system information carrying the identification information to the terminal.
And when the identification information is NHN-ID, the system information is carried in an anchor channel and/or a data channel.
And when the identification information is PSP-ID, the system message is carried in a data channel.
Further, an anchor channel and a data channel are introduced:
the eMTC-MF system is a frequency hopping system working at 2.4 GHz, and has 56 frequency hopping points, an anchor channel is sent between two frequency hopping (namely, data channels), and one signal transmission period comprises one-time transmission of the anchor channel and one-time transmission of the data channels. And due to the limitation of the LBT mechanism and the repeated transmission of the signal, the whole signal transmission period is long.
The Anchor Channel is an english full name and is used to carry a Discovery Reference Signal (DRS), where the DRS includes main downlink broadcast signals including a system message Block (SIB) and a main system message Block (MIB). Specifically, in the embodiment of the present invention, the system message on the bearer and Anchor channel is SIB, and for simplicity and convenience in description, the system message on the Anchor channel is abbreviated as SIB-Anchor, or abbreviated as SIB-a.
The Data Channel, known as Data Channel in english, is used for carrying Data signals, and includes a first system message (SIB1), a second system message (SIB2), and the like. Specifically, in the embodiment of the present invention, the system message on the bearer and the data channel is SIB1 or SIB2, and for simplicity, the first system message on the data channel is abbreviated as SIB1-BR (Bandwidth Reduction), and the second system message on the data channel is abbreviated as SIB 2.
Specifically, the DRS transmitted by the anchor channel is used to schedule the data signal. The MIB contains the scheduling information of SIB1-BR, the system frame number, the subframe offset, the SIB-A size, the period of SIB1-BR, and other information. The SIB-A includes information such as system message change label, channel list, superframe number, paging indication, uplink and downlink subframe configuration, and the number of idle channel detection subframes.
The method for transmitting the identification information provided by the embodiment of the invention carries the identification information in the system message carried on the anchor channel and/or the data channel so as to transmit the NHN-ID and the PSP-ID, and the terminal can receive and access the neutral host and the operator network based on the identification information.
Further, for early transmission of HNH-ID, it is chosen that SIB-a carries NHN-ID, but NHN-ID usually occupies larger resources, and SIB-a does not necessarily have enough space to carry all the information of NHN-ID. Therefore, in combination with the foregoing method flow, when the sent identification information is an NHN-ID, another possible implementation manner of the embodiment of the present invention further provides the following two possible implementation methods for how to send the information with the NHN-ID in step 101.
A first implementation method, in which SIB-a carries all information of NHN-ID, as shown in fig. 2, includes the following steps:
1011. and the network equipment sends a system message SIB-A on an anchor channel to the terminal, wherein the SIB-A carries all information of NHN-ID.
In a first implementation, SIB-A has enough space to carry all the information of NNHN-ID independently.
It should be noted that the terminal may not continue to try the cell corresponding to the NHN-ID that is not supported by the terminal itself after acquiring the NHN-ID through SIB-a. For a specific example, when the terminal performs cell reselection, the terminal finds the DRS of a certain cell on an anchor channel, and directly searches the DRS of the next cell when acquiring that the corresponding NHN-ID does not belong to a previously accessed cell.
The second implementation method, in which SIB-a and SIB1-BR carry all the information of NHN-ID together, as shown in fig. 3, includes the following steps:
1012. and the network equipment sends SIB-A to the terminal, wherein the SIB-A carries the first part information of the NHN-ID.
The first part of the information of the NHN-ID may be a short NHN-ID (e.g., a hash ID or a first half of HNH-ID, etc.).
1013. And the network equipment sends a first system message SIB1-BR on a data channel to the terminal, wherein the SIB1-BR carries second part information of the NHN-ID.
Wherein, the second part of information of the NHN-ID is the residual information of all the information except the first part of information. That is, the first partial information of the NHN-ID and the second partial information of the NHN-ID constitute the entire information of the NHN-ID.
In the second implementation method, the SIB-A in combination with SIB1-BR in the same signal transmission period carries all the information of the NHN-ID. For example, if the size of the NHN-ID is 40 bits, the short NHN-ID of N bits is sent in SIB-A, wherein the short NHN-ID is the first N bit of the NHN-ID, and the NHN-IDs of the remaining (40-N) bits are sent in SIB 1-BR.
It should be noted that the terminal may not continue to try the cell corresponding to the short NHN-ID that is not supported by the terminal itself after acquiring the short NHN-ID through SIB-a. For a specific example, when the terminal performs cell reselection, the terminal finds the DRS of a certain cell on an anchor channel and knows that the corresponding short NHN-ID does not belong to a previously accessed cell, and then directly searches the DRS of the next cell. And if the terminal prestores the NHN-ID supported by the terminal, when the neutral host network is found, the complete NHN-ID can be further acquired by preferentially searching the cell of the short NHN-ID supported by the terminal.
In an eMCT-MF system, the NHN-ID is sent in a carrying way through the two implementation methods, and because the SIB-A and the SIB1-BR have relatively short sending periods, the terminal can acquire the NHN-ID of the neutral host network as early as possible and further judge whether the NHN-ID is supported by the terminal, so that cell reselection can be completed quickly, and time delay and power consumption when the terminal is accessed to the network are reduced.
Further, for early transmission of PSP-IDs, the SIB1-BR would be chosen to carry PSP-IDs, but a neutral host network may have multiple corresponding PSP-IDs, while a SIB1-BR transmitted at one time (within one signaling cycle) may not have enough space to carry all PSP-IDs. Therefore, in combination with the foregoing method flow, when the transmitted identification information is a PSP-ID, another possible implementation manner of the embodiment of the present invention further provides the following three possible implementation methods for how to carry the PSP-ID for transmission in step 101.
The first implementation method, in which all PSP-IDs are carried by a SIB1-BR transmitted at one time, as shown in fig. 4, includes the following method flows:
1014. and the network equipment sends SIB1-BR carrying all PSP-IDs to the terminal.
In the first implementation method, the SIB1-BR transmitted at one time has enough space to independently carry all (i.e. M) PSP-IDs.
The second implementation method, in which SIB1-BR is combined with SIB2 to carry PSP-ID, as shown in fig. 5, includes the following steps:
1015. the network equipment sends SIB1-BR carrying L1 PSP-IDs to the terminal.
1016. And the network equipment sends a second system message SIB2 on a data channel carrying L2 PSP-IDs to the terminal.
Wherein, L1+ L2 ═ M.
In a second implementation, SIB1-BR carries all PSP-IDs in combination with SIB 2.
In a third implementation method, an SIB1-BR transmitted at multiple SIB1-BR transmission time (multiple times, within multiple signal transmission periods) carries several PSP-IDs in turn, as shown in fig. 6, including:
1017. the network equipment sends a carrying k at the sending time of the first SIB1-BR1SIB1-BR of PSP-ID to the terminal.
1018. The network equipment sends a carrying k at the sending time of a second SIB1-BR2SIB1-BR of PSP-ID to the terminal.
1019. And by analogy, the network equipment sends a carrier k at the (N-1) SIB1-BR sending timeN-1SIB1-BR of PSP-ID to the terminal.
1019', the network device transmits a carrier k at the (N) th SIB1-BR transmission timeNSIB1-BR of PSP-ID to the terminal.
Wherein N is>1，k1+k2+…+kN-1+kN≥M，kJ≠0，J＝1、2…N-1、N。
Preferably, k isJThe current SIB1-BR can carry at most the number of PSP-IDs.
When the SIB1-BR carries T PSP-IDs at most and the number of PSP-IDs contained in the current network is M (M > T), the SIB1-BR which is transmitted once cannot carry all the PSP 1-IDs, and the SIB1-BR which is transmitted many times is polled, so that all the PSP-IDs can be transmitted as early as possible. Specifically, for example, the M PSP-IDs are divided into M/T (integer) PSP-ID subgroups according to a cyclic shift manner, and the SIB1-BR alternately carries the PSP-ID subgroups at the transmission time of the SIB1-BR for transmission. It should be noted that, for the change of the PSP-ID transmission sequence in the SIB1-BR, the network device does not need to trigger the connected terminal to re-read the SIB1-BR (for example, by keeping the SIB1-BR change flag unchanged), and no additional power consumption is caused to the connected terminal. It is further noted that in the sub-groups of PSP-IDs carried by the SIB-BRs transmitted at the transmission time of the different SIB 1-BRs, the PSP-IDs may overlap, i.e. the total number of PSP-IDs carried by the different SIB 1-BRs may be greater than M.
In an eMCT-MF system, PSP-ID is sent in a carrying manner through the three implementation methods, because the sending periods of SIB1-BR and SIB2 are relatively short, the terminal can acquire the PSP-ID of the neutral host network as early as possible, and then judge whether the PSP-ID is the PSP-ID supported by the terminal, and the terminal can search the next neutral host network as early as possible when the PSP-ID supported by the terminal does not exist, so that the terminal can quickly complete network access of an operator, and further reduce time delay and power consumption when the network is accessed.
Further, when the three implementation methods are used for carrying and sending the PSP-IDs, and when the SIB1-BR transmitted at one time cannot carry all the PSP-IDs, the network device may further remind the terminal that all the PSP-IDs are not sent through the indication information, so that the terminal continues to receive the system message to obtain the remaining PSP-IDs.
Therefore, in the second implementation method, when SIB1-BR is combined with SIB2 to carry PSP-ID, in a possible implementation process, the SIB1-BR may also carry indication information, where the indication information is used to indicate that the subsequent SIB2 also carries PSP-ID.
In a third implementation method, that is, when the SIB1-BR transmitted by multiple SIB1-BR transmission times carries several PSP-IDs in turn, in a possible implementation process, the SIB1-BR transmitted at the (N-1) th SIB1-BR transmission time may further carry indication information, where the indication information is used to indicate that the SIB1-BR transmitted at the subsequent (N) th SIB1-BR transmission time also carries a PSP-ID, and 1< N ≦ N.
