Description

Method for realizing multicast broadcast service, communication system, communication device, and terminal

technical field

The present invention relates to a communication method and system thereof, in particular to a method for realizing a multicast broadcast service, a communication system, a communication device and a terminal. the

Background technique

Multimedia Broadcast Multicast Service (MBMS, Multimedia Broadcast Multicast Service) is a broadcast and multicast technology introduced in the sixth version (R6, Release 6) of the third generation cooperation project (3GPP, 3rd Generation Project Partner), which is based on the mobile communication network Provides multicast broadcast functionality. 3GPP also clearly proposes to support enhanced MBMS in its work plan of Radio Access Technology (RAT, Radio Access Technology) Long Term Evolution (LTE, Long Term Evolution) and System Architecture Evolution (SAE, System Architecture Evolution). the

In the structure of the current LTE/SAE system, the access network mainly includes an evolved Node B (eNB, evolvedNode B), which provides a terminal-oriented air interface and is connected to the core network. The core network mainly includes a user plane entity (UPE, User Plane Entity)/mobility management entity (MME, Mobility Management Entity). Among them, the UPE is responsible for user plane data transmission and processing, and the MME is mainly responsible for mobility management. the

The MBMS service is a broadcast multicast service provided in the mobile communication network. When the system is configured with many MBMS services, the extra system spectrum resources are usually configured as dedicated MBMS carrier frequencies, that is to say, the carrier frequencies will not be used To transmit non-MBMS business. In 3GPP R6, the spectrum bandwidth supported by the system is fixed at 5MHz. The MBMS dedicated carrier frequency and the common carrier frequency in the same area are two completely independent spectrum resources, which form adjacent inter-frequency cells. This is called the first type of MBMS Dedicated carrier frequency. In LTE, the system can support spectrum bandwidths ranging from 1.25MHz to 20MHz, and MBMS dedicated carrier frequencies can be adjacent to common carrier frequencies in the same area as in 3GPP R6. Different frequency cells (as shown in Figure 1 ), can also form a continuous frequency band with higher bandwidth together with the common carrier frequency in the same area, so they are different frequency resources in the downlink frequency band of a cell (as shown in Figure 2), which is called the second type of MBMS dedicated carrier frequency. the

In the 3GPP R6 system configured with MBMS-dedicated carrier frequency, that is, in the LTE system configured with the first type of MBMS-dedicated carrier frequency, ordinary terminals can only work at one frequency point at the same time, so if the terminal receives MBMS services, it is impossible to receive non-MBMS carrier frequency information at the same time. In order to receive non-MBMS carrier frequency information, a method in the prior art is to allow a terminal with a lower capability to periodically switch to a common carrier frequency to monitor whether there is a paging message indicating the arrival of other non-MBMS services. However, due to the above method, the terminal with lower capabilities may need to stop receiving MBMS services, so that programs cannot be continuously received, which affects user experience. the

In order to ensure that terminals with lower capabilities will not miss ordinary mobile communication services when using MBMS services, and can use MBMS services uninterruptedly when no other services arrive, the current method is: when the target user is in the paging area When the MBMS dedicated carrier frequency is configured, the user is paged on the MBMS dedicated carrier frequency. the

On the other hand, because the MBMS service allows the terminal to receive it in an idle state, that is, the terminal can receive the MBMS service without sending any instructions to the network, so the network does not know whether the terminal is receiving the MBMS service and working on the dedicated MBMS carrier frequency. Therefore, the prior art solution also simultaneously paging users on non-MBMS dedicated carrier frequencies. the

That is to say, in the prior art solution, in order to take care of possible low-capability terminals, when the MBMS dedicated carrier frequency is configured in the paging area where the target user needs to be paged, no matter whether the terminal is a high-capability terminal or a low-capability terminal, , the system will simultaneously page users on two carrier frequencies dedicated to MBMS and carrier frequencies not dedicated to MBMS. the

However, high-capability terminals can receive data on MBMS-dedicated carrier frequencies and non-MBMS-dedicated carrier frequencies at the same time. Therefore, when users use such high-capability terminals to receive MBMS services on MBMS-dedicated Frequently paging the user causes the user's high-capability terminal to receive two pages simultaneously. This requires the high-capability terminal to be able to recognize that the two pages are the same page, and to perform corresponding operations to avoid repeated processing of the same paging, thus increasing the complexity of the high-capability terminal to process paging messages to a certain extent . Moreover, since high-capability terminals must be able to receive MBMS services from non-MBMS-dedicated carrier frequencies at this time, sending paging messages on MBMS-dedicated carrier frequencies also wastes certain air interface resources in the prior art. the

Detailed ways

The basic principle of the present invention is: in the communication system applicable to MBMS service, the terminal indicates its ability to the network when accessing the network, and the ability is the ability to support simultaneous reception of MBMS dedicated carrier frequency and non-MBMS dedicated carrier frequency. The network side saves this information, and judges based on it whether it is necessary to page the user on the MBMS dedicated carrier frequency. By adopting the above-mentioned technical means, the network can distinguish between high-capability terminals and low-capability terminals, and avoid paging users using high-capability terminals on two MBMS-dedicated carrier frequencies and non-MBMS-dedicated carrier frequencies at the same time. the

A basic embodiment of the present invention is as follows:

A method for realizing a multicast broadcast service is provided, including steps:

When accessing the network, the terminal indicates the capability of the terminal to the network, the capability is the ability to support simultaneous reception of MBMS-dedicated carrier frequencies and non-MBMS-dedicated carrier frequencies;

When the terminal supports simultaneous reception of MBMS-dedicated carrier frequency and non-MBMS-dedicated carrier frequency, the network only pages the terminal on the non-MBMS-dedicated carrier frequency. the

Since the terminal indicates the terminal capabilities to the network, the network can know whether the accessed terminal is a high-capability terminal or a low-capability terminal. When the capability information received by the network indicates that the bandwidth supported by the terminal is equal to or greater than the network bandwidth, or the terminal is at least When two receivers are included, it means that the terminal is a high-capacity terminal that supports simultaneous reception of MBMS-dedicated carrier frequencies and non-MBMS-dedicated carrier frequencies, and does not need to simultaneously page users on MBMS-dedicated carrier frequencies and non-MBMS-dedicated carrier frequencies. The terminal is thus only paged on non-MBMS dedicated carrier frequencies. Reduce the complexity of terminal design and save communication air interface resources. the

The present invention will be described in detail below in conjunction with the embodiments and the accompanying drawings. the

Referring to Fig. 3, the first embodiment of the implementation method of the multicast broadcast service of the present invention includes steps:

301. The terminal searches for a network including an evolved Node B and a mobility management entity. Wherein, the evolved Node B belongs to the access network part, and the mobility management entity belongs to the core network part. the

302. The terminal receives system broadcast information from the searched network, and reads the information necessary for the network attachment process, including whether the network supports: the ability to determine whether to only page users on non-MBMS dedicated carrier frequencies based on terminal capabilities. In this example For yes. the

303. An RRC (Radio Resource Control, radio resource control) connection establishment process is initiated between the terminal and the evolved Node B. the

304. The terminal and the mobility management entity execute a network attachment procedure using a non-access stratum message to access the network. According to the information in the received system broadcast message, the terminal judges whether the network supports the ability to determine whether to page users only on non-MBMS dedicated carrier frequencies based on terminal capabilities. If so, the terminal indicates to the network the capability of the terminal, the capability is the ability to support simultaneous reception of MBMS-dedicated carrier frequencies and non-MBMS-dedicated carrier frequencies, specifically, the capability may be how much bandwidth the terminal supports, whether it is equal to or Greater than the network bandwidth, may also refer to whether the terminal is at least two receivers. the

The specific process is: execute the network attachment process, in the first non-access layer message that the terminal sends to the network, that is, the attach message, whether the carrying terminal supports the ability to receive MBMS-dedicated carrier frequencies and non-MBMS-dedicated carrier frequencies at the same time, in this example For yes. The mobility management entity saves this information in the mobility management context of the user equipment (terminal). the

305. When the network needs to page the user, the mobility management entity judges whether the terminal used by the user supports simultaneous reception of MBMS-dedicated carrier frequency and non-MBMS-dedicated carrier frequency according to the information in the user's mobility management context, and the mobility management entity evolves to When the terminal supports receiving MBMS-dedicated carrier frequencies and non-MBMS-dedicated carrier frequencies at the same time, the paging user message carries an indication that the terminal is paging only on non-MBMS-dedicated carrier frequencies, or the The paging user message only includes the cell identity corresponding to the non-MBMS dedicated carrier frequency in the paging area;

306. When the corresponding paging user message carries an indication that the terminal is paged only on the non-MBMS dedicated carrier frequency, the access network only pages the terminal on the non-MBMS dedicated carrier frequency; the corresponding paging user message only includes the non-MBMS dedicated carrier frequency. In the case of the cell ID corresponding to the MBMS dedicated carrier frequency, the evolved Node B pages the user in the corresponding cell according to the cell ID. the

In step 302, if the network does not support: the ability to determine whether to page users only on non-MBMS-dedicated carrier frequencies based on terminal capabilities, then the network returns a failure response to the terminal in step 304, or at the same time on MBMS-dedicated carrier frequencies and non-MBMS-dedicated carrier frequencies Paging the terminal on the carrier frequency. the

In step 305, if the bandwidth supported by the terminal is smaller than the network bandwidth, or the terminal is a single receiver, that is, the terminal does not support simultaneous reception of MBMS-dedicated carrier frequency and non-MBMS-dedicated carrier frequency, the MBMS-dedicated carrier frequency and non-MBMS-dedicated carrier frequency Simultaneously paging users on MBMS dedicated carrier frequency. This scheme corresponds to the case of low-capability terminals. the

Both the RRC connection establishment process in step 303 and the network attachment process in step 304 belong to the process of terminal accessing the network. the

It can be seen from the above that since the terminal indicates the terminal capability to the network by adding capability information in the non-access stratum message in step 304, the network can know whether the terminal being accessed is of high capability or low capability in step 305. Capability terminal, when the capability information received by the network indicates that the bandwidth supported by the terminal is equal to or greater than the network bandwidth, or the terminal is a dual-receiver, three-receiver or contains more receivers, it means that the terminal is a high-capability terminal, Supports the ability to simultaneously receive MBMS-dedicated carrier frequencies and non-MBMS-dedicated carrier frequencies, and does not need to simultaneously page users on MBMS-dedicated carrier frequencies and non-MBMS-dedicated carrier frequencies, so in step 306 only paging the user on non-MBMS-dedicated carrier frequencies terminal, or only paging the terminal in the cell corresponding to the non-MBMS dedicated carrier frequency. There is no need to consider the problem of avoiding repeated processing of paging messages, reducing the complexity of terminal design, saving communication air interface resources, and avoiding waste. the

Referring to Fig. 4, the second embodiment of the implementation method of the multicast broadcast service of the present invention includes steps:

401. The terminal searches for a network, and the network includes an evolved Node B and a mobility management entity. Wherein, the evolved Node B belongs to the access network part, and the mobility management entity belongs to the core network part. the

402. The terminal receives system broadcast information from the searched network, and reads the information necessary for the network attachment process, including whether the network supports: the ability to determine whether to only page users on non-MBMS dedicated carrier frequencies based on terminal capabilities. In this example For yes. the

403. The terminal initiates an RRC (Radio Resource Control, radio resource control) connection establishment process between the terminal and the evolved Node B, and under certain conditions, simultaneously indicates the terminal capability to the network. Specifically, it means that the terminal sends a radio resource control connection request message carrying the terminal capability information to the access network. The capability is the ability to support simultaneous reception of MBMS-dedicated carrier frequencies and non-MBMS-dedicated carrier frequencies. Specifically, the capability may be how much bandwidth the terminal supports, whether it is equal to or greater than the network bandwidth, or whether the terminal includes at least Two receivers. the

The condition is: according to the information in the received system broadcast message, the terminal judges whether the network supports: the ability to determine whether to page users only on non-MBMS dedicated carrier frequencies based on terminal capabilities. If yes, the terminal indicates terminal capabilities to the network. the

404. The access network reports the terminal capability to the core network. The mobility management entity stores this capability information in the mobility management context of the user equipment (terminal). the

405. When the network needs to page the user, the mobility management entity judges whether the terminal used by the user supports simultaneous reception of MBMS-dedicated carrier frequency and non-MBMS-dedicated carrier frequency according to the information in the user's mobility management context, and the mobility management entity evolves to The Node B of the mobile station sends a paging user message; when the terminal supports simultaneous reception of MBMS-dedicated carrier frequencies and non-MBMS-dedicated carrier frequencies, the paging user message carries an indication that the terminal is paging only on non-MBMS-dedicated carrier frequencies, or the The paging user message only includes the cell identity corresponding to the non-MBMS dedicated carrier frequency in the paging area;

406. In the case where the corresponding paging user message carries an indication that the terminal is paged only on the non-MBMS dedicated carrier frequency, the access network only pages the terminal on the non-MBMS dedicated carrier frequency; the corresponding paging user message only includes the non-MBMS dedicated carrier frequency. In the case of the cell ID corresponding to the MBMS dedicated carrier frequency, the evolved Node B pages the user in the corresponding cell according to the cell ID. the

Apparently, this embodiment has the same technical effect as the first embodiment. the

Referring to FIG. 5 , the present invention also provides a communication system, the first embodiment of which includes a network and a terminal 510 , the terminal 510 includes a capability information generation unit 511 , and the network includes a core network 530 and an access network 520 . The core network 530 includes a terminal capability identification unit 531 and a paging channel selection unit 532 . the

The capability information generation unit 511 is used to generate capability information of the terminal 510 where the capability is the bandwidth supported by the terminal 510 or whether the terminal 510 includes at least two receivers; The capability information of the terminal 510 is generated in a non-access stratum message sent to the core network 530 . The terminal 510 sends the capability information to the network when accessing the network. the

After the core network 530 receives the non-access layer message from the terminal 510, the terminal capability identification unit 531 is used to judge whether the bandwidth supported by the terminal 510 is equal to or greater than the network bandwidth according to the capability information, or to judge whether the terminal 510 At least two receivers are included, and the judgment result is obtained. the

The paging channel selection unit 532 obtains the judgment result of the terminal capability identification unit 531, when the judgment result shows that the bandwidth supported by the terminal 510 is equal to or greater than the network bandwidth, or when the terminal 510 includes at least two receivers The paging channel selection unit 532 is configured to generate in the paging user message an indication of only paging the terminal on a non-MBMS dedicated carrier frequency, or generate only a cell identity corresponding to a non-MBMS dedicated carrier frequency within the paging area. And instruct the core network 530 to send the paging user message carrying the channel indication to the access network 520 . the

When receiving the paging user message, corresponding to the case where the paging user message carries an indication of paging the terminal 510 only on the non-MBMS dedicated carrier frequency, the access network 520 only pages the terminal 510 on the non-MBMS dedicated carrier frequency; Corresponding to the case where the user paging message only includes the cell ID corresponding to the non-MBMS dedicated carrier frequency in the paging area, the access network 520 pages the user in the corresponding cell according to the cell ID. the

In addition, before the terminal 510 sends a non-access stratum message to the core network 530, the terminal 510 receives system broadcast information from the searched network, and reads information necessary for the network attachment process, including whether the network supports: Whether it is only capable of paging users on a non-MBMS dedicated carrier frequency, the terminal 510 may generate terminal 510 capability information in a non-access stratum message sent to the core network 530 when the network supports it. If the network does not support it, no capability information is generated and a non-access stratum message is sent. the

If the core network 530 knows that the bandwidth supported by the terminal 510 is smaller than the network bandwidth, or the terminal 510 is a single receiver, that is, the terminal 510 does not support receiving MBMS-dedicated carrier frequencies and non-MBMS-dedicated carrier frequencies at the same time, the paging The channel selection unit 532 selects to simultaneously page users on MBMS-dedicated carrier frequencies and non-MBMS-dedicated carrier frequencies. the

It can be seen from the above that, since the capability information generation unit 511 is used to add capability information to the non-access stratum message to indicate the capabilities of the terminal 510 to the network, the terminal capability identification unit 531 on the network side can know that the terminal 510 connected Whether it is a high-capability or low-capability terminal, when the capability information received by the network indicates that the bandwidth supported by the terminal 510 is equal to or greater than the network bandwidth, or the terminal 510 includes at least two receivers, it means that the terminal 510 is a high-capability terminal 510 , support the ability to simultaneously receive MBMS-dedicated carrier frequencies and non-MBMS-dedicated carrier frequencies, and do not need to simultaneously paging users on MBMS-dedicated carrier frequencies and non-MBMS-dedicated carrier frequencies, so the paging channel selection unit 532 selects only The terminal 510 is paged on the frequency, or the terminal 510 is only paged in the cell corresponding to the non-MBMS dedicated carrier frequency. There is no need to consider the problem of avoiding repeated processing of paging messages, reducing the design complexity of the terminal 510, saving communication air interface resources, and avoiding waste. the

Referring to FIG. 6 , the second embodiment of the communication system of the present invention is similar to the first embodiment of the above-mentioned communication system, except that: the capability information generation unit 611 generates a terminal in the radio resource control connection request message sent to the access network 620 capability information. When receiving the radio resource control connection request message, the access network 620 is configured to report the terminal capability to the core network 630 . Apparently, this embodiment has the same technical effect as the first embodiment. the

Referring to FIG. 7 , the present invention also provides a communication device 730 , including a terminal capability identification unit 731 and a paging channel selection unit 732 . The terminal capability identifying unit 731 is used to judge whether the terminal supports simultaneous reception of MBMS-dedicated carrier frequency and non-MBMS-dedicated carrier frequency according to the received terminal capability information, and obtain the judgment result. The paging channel selection unit 732 obtains the judgment result of the terminal capability identification unit 731, and when the judgment result shows that the terminal supports simultaneous reception of MBMS-dedicated carrier frequencies and non-MBMS-dedicated carrier frequencies, selects only the non-MBMS-dedicated carrier frequency Page the terminal. In this embodiment, the communication device 730 is a mobility management entity of the core network. the

It can be seen from the above that since the terminal capability identification unit 731 is used to identify whether the terminal being accessed is a high-capability terminal or a low-capability terminal, when the capability information received by the network indicates that the terminal supports simultaneous reception of MBMS-dedicated carrier frequency and non-MBMS-dedicated carrier frequency support When the bandwidth is equal to or greater than the network bandwidth, there is no need to simultaneously page the user on the MBMS-dedicated carrier frequency and the non-MBMS-dedicated carrier frequency, so the paging channel selection unit 732 selects to only page the terminal on the non-MBMS-dedicated carrier frequency. Save communication air interface resources and avoid waste. the

Referring to FIG. 8 , the present invention also provides a terminal 810 , including a capability information generating unit 811 and a channel setting unit 812 . The capability information generating unit 811 is configured to generate capability information of the terminal 810 where it is located. The capability is the ability to support simultaneous reception of MBMS-dedicated carrier frequencies and non-MBMS-dedicated carrier frequencies. When accessing the network, the terminal 810 sends the capability information to the network. After knowing the capabilities of the terminal 810, the network returns a paging user message carrying channel indication information. The channel setting unit 812 is configured to instruct the terminal 810 to receive network paging only on the non-MBMS dedicated carrier frequency when receiving a paging user message from the network indicating that the terminal is paged on the non-MBMS dedicated carrier frequency. the

It can be seen from the above that since the capability information generation unit 811 is used to generate the capability information to indicate the capability of the terminal 810 to the network, when the network knows that the terminal 810 does not need to be paged on the MBMS-dedicated carrier frequency and the non-MBMS-dedicated carrier frequency at the same time, the After receiving the network instruction, the channel setting unit 812 instructs the terminal 810 to receive network paging only on the non-MBMS dedicated carrier frequency. There is no need to consider the problem of avoiding repeated processing of paging messages, which reduces the design complexity of the terminal 810 . the
