Description

Method for multimedia service transmission, user equipment and network entity thereof

technical field

The present invention relates to a method of multimedia service transmission and its user equipment and network entity, wherein the network entity is used to control information related to multimedia service transmission fed back from a single receiver/transmitter user equipment, so as to adjust multimedia service transmission. The information related to multimedia service transmission is generated in the user equipment. the

Background technique

To be able to detect performance issues in a telecommunication system, or to perform fault diagnosis, or to adjust configurable parameters in a telecommunication system, data cyclic collection techniques are used, in particular statistics and counters. The techniques described above are used in all major terrestrial wide area wireless systems today, such as Global System for Mobile Communications (GSM) or Wideband Code Division Multiple Access (WCDMA) systems. Typically, data collection may be collected from each network node at regular intervals, for example, every 15 minutes. In this way, the data can be post-processed in the operations and maintenance (O&M) system, ie key performance indicators are calculated and possibly operator alerts generated, typically when performance drops below a certain level. Performance reports, read by operators supervising the O&M system, are also generated at regular intervals to trigger manual corrections. In addition, input data can be automatically generated to other systems to support adjustments to the O&M system. Typically, the post-processed data can be used for troubleshooting and network tuning, as well as for determining network resource requirements in various situations, such as determining network resource requirements during initial network installation, or after another equipment expansion Determination of network resource requirements at installation time. This allows performance to be verified and operation corrected after software upgrades, and problems that would otherwise go undetected can be detected. The data collected in the manner described above, and the data used in the techniques described above are hereinafter referred to as counter or statistical data. the

In wireless systems employing the data collection and performance estimation techniques described above, the counters or statistics collected are often associated with successful, unsuccessful or incomplete telecommunication procedures in the call control interface or user interface, e.g. The number of detected random access attempts, the number of successful random accesses, the number of user equipment (UE) session establishments, the number of UE sessions revoked in different UE states, and the like. the

Typically, counters or statistics are maintained per network entity, not actually per session, eg per call, per location area etc. data. Typically, the UE itself does not directly collect or communicate or participate in any of the aforementioned counter collections. Counters related to the radio interface are collected at the end of the network. The UE makes measurements that need to be reported to the network (base station, etc.), but such measurements are usually not used for O&M post-processing and performance estimation. The measurement results of the UE are usually used in an algorithm implemented by a real-time machine, so as to trigger a handover or an uplink switch of a bitrate, etc. All counters or statistics are usually collected from the network (base stations, etc.). In the past, one of the main reasons for avoiding measuring and collecting counters or statistics in the UE was to avoid extra load on the radio interface for reporting. the

Terrestrial broadcasting services used by small mobile devices with smaller antennas, such as mobile television (TV) in mobile phones, have received a lot of attention in the industry, such as multimedia broadcasting and Multicast Service (MBMS). For the CDMA2000 system, similar services are proposed. In addition, independent broadcasting systems such as DVB-H have also been developed. All technologies for terrestrial broadcast services for small (ie, carried by humans) mobile devices and related technologies are hereinafter referred to as MBMS or Multimedia Services. the

In order to facilitate the realization of broadcast services, it is possible to adopt an MBMS system with only downlink unidirectional link transmission, that is, the information stream flows from the base station (BS) to the UE through a wireless interface in a non-duplex communication manner. A unique benefit of DL-only systems is that no radio spectrum resources are required for the uplink (UL). Radio carriers and spectrum resources are only used in DL. Another benefit of a DL-only system is that the radio characteristics of the UL can be ignored. Thus, such a system can develop an efficiency-optimized DL-only base station with high output power and large coverage area. The above-mentioned MBMS system using only wireless DL is subsequently called an MBMS Dedicated Carrier (DC) system or simply a DC system. the

A terrestrial wireless system may be referred to as an MBMS Mixed Carrier (MC) system, or simply a Mixed Carrier (MC) system. The terrestrial wireless system among them has MBMS functionality or technology, and can process UL transmission on the same wireless spectrum resource for DL, or on a wireless spectrum resource paired with the spectrum resource of DL. The UL in MBMS MC systems can be used for UL signaling and/or for non-MBMS services requiring UL, such as unicast services, see below. the

Another type of terrestrial wireless system, hereafter referred to as a unicast capable system or simply a unicast (UC) system. This other one of the terrestrial wireless systems is capable of point-to-point communication between the BS and the UE, which can be uplink or downlink or uplink and downlink communication. Typical UC user services include voice calls, video calls, Internet web browsing, sending short messages, and so on. the

The MBMS DC system is generally deployed to cover the UC network, that is, the geographic coverage of the DC and UC systems overlaps. Overlapping DC and UC systems may use the same/different network devices and network resources or a combination thereof. For example, the deployment scheme of the above-mentioned MBMS DC system can be foreseen in the discussion of 3GPP. In 3GPP, the MBMS DC system usually covers UCGSM, WCDMA, and Long-Term Evolution (LTE) networks, and a typical UE is suitable for use by MCs. Or MBMS service distributed by DC, and UC service. the

As mentioned above, network operators typically initiate network adjustments based on the results of statistical data collection and post-processing. Protocol parameters are optimized to give the best performance for experienced users, radio and antenna parameters are optimized to obtain better coverage, and other optimizations result in an optimized network. In the operation of the network, the above-mentioned network adjustment for optimizing the network is a continuous process. the

Statistics also play an important role in problem detection, for example, if a specific function or a specific resource fails completely, network performance will drop to a low level. Such failures would be difficult to detect by means other than the use of statistical data. the

MBMS DC systems are particularly problematic in this respect mentioned above. For the MBMSDC system, there is no two-way interaction between uplink and downlink on the wireless interface, and there is no statistical data counter in the network to collect information related to user transmission experience. There are no successful, unsuccessful, completed or incomplete procedures in the wireless user interface or control interface to enable counting. the

However, MBMS DC systems have problems with geographical coverage and the need to adjust radio and antenna parameters. In MBMS DC systems, function and resource failures may be difficult to detect. Therefore, it is necessary to provide a function similar to statistical data collection in the MBMS DC system. the

Likewise, for MBMS MC systems, there is little bidirectional interaction over the radio interface in normal operation. Although UL exists, its use in MBMS MC systems is very limited. Therefore, unless a special interaction process is defined for the maintenance of statistical data and counters at the network side, the MBMSMC system has similar statistical data collection problems as the MBMS DC system. the

Practically all unidirectional transmission systems share the above issues and needs to some extent, but they are most pronounced in terrestrial wireless systems where the geography of the land and the implementation/structure of the distributed network complicate the issue. the

Although it is not common for UEs to measure and report statistics, this concept is well known. For 3GPP MBMS Rel-6, after the session is completed, UE can be requested to make a statistical report. This request is embedded in the data received by the UE at service discovery/service notification. Existing mechanisms include reporting of quality metrics such as Corruption Duration, Rebuffering Duration, Initial Buffering, Continuous Loss of RTP Packets, Frame Rate Deviation, and Jitter Duration. Existing mechanisms also include the ability to scale reporting over time so that only a small subset of UEs are requested to report and load peaks are reduced. the

Existing methods for user equipment to collect and report statistical data include the following problems. the

1. The fault diagnosis of the wireless access network is not considered. There is no means in the prior art to correlate radio status with application-level quality issues, nor to correlate application-level issues with specific geographic regions. Only mobile devices actively receiving MBMS transmissions may be requested to report results of statistical measurements. the

2. The load control of the prior art is not sufficient because the load control of the wireless interface is not considered. Furthermore, in the prior art, load control does not change adaptively as the number of UEs in the network changes. the

3. The measurement request is integrated in the service notification/service discovery mechanism. This creates a long lead time for measurement requests relative to the actual session, so requests for immediate or on-demand measurements required for troubleshooting cannot be fulfilled. the

A single receiver/transmitter user equipment as defined in this specification can only receive and/or transmit data on one wireless carrier at any time, but it allows both transmission and reception of signals. Thus a single receiver/transmitter user equipment can both receive and transmit signals. the

A single-receiver/transmitter MBMS UE, i.e. a single-receiver/transmitter user equipment as defined above, is capable of doing the above when receiving MBMS, or when not otherwise receiving MBMS, or while running a UC application The requested MBMS measurement. the

However, since the time required to report measurements is likely to exceed the time between transmission bursts of MBMS data, a single receiver/transmitter UE is reporting Problems arise in the process of measuring results. When only considering the MC scheme of MBMS and UC operation performed on the same carrier, since a single receiver/transmitter user equipment cannot simultaneously receive and transmit signals on the same carrier, it is impossible to report both when receiving MBMS data The measurement result does not interrupt the reception of MBMS data. If you also consider the case where the MBMS DC overlays the UC network via another radio carrier, since the time gap required to leave the DC to perform UC operations (e.g. measurement reports) is larger than on the same carrier (and on the same/similar radio the time gap required to enter the technology), the above-mentioned problems will become more serious. the

Contents of the invention

The main object of the present invention is to provide a method for transmitting multimedia services over a terrestrial wireless network, wherein the information related to the transmission of multimedia services is generated in at least one user equipment with only one receiver/transmitter, in order to transmit multimedia services The transmission is adjusted. the

These above-mentioned features and other advantageous features will be described in detail below. the

The invention will be described in more detail below with reference to the accompanying drawings of preferred embodiments of the device of the invention. the

Description of drawings

Fig. 2 schematically shows another embodiment of the system for multimedia service transmission and statistics report according to the present invention. the

Fig. 3 schematically shows an embodiment of a system according to the present invention, the system is used for multimedia service transmission, statistics report and user equipment measurement control. the

Detailed ways

In the following description, the same reference numerals refer to similar features in different drawings. the

Fig. 1 schematically shows a system for multimedia service transmission and statistical reporting according to the present invention. the

In the present invention, the user equipment performs performance related measurements and maintains counters related to user experience and reception of wireless transmissions of MBMS transmissions in order to generate information related to said multimedia transmissions. The UE will report, ie feed back, results such as statistics and/or counters to the network entities. In this way, when the network itself cannot maintain statistical data for MBMS DC, and MBMS MC does not adopt a special program to maintain statistical data and counters in the network, it is possible to detect, measure and analyze the relationship between user experience and transmission Receiving related issues to enable corrections/adjustments to the radio access network. Preferably, said data is post-processed data in the operation and maintenance system. the

Figure 1 shows that the UE performs statistical measurement and reports to the network. the

As shown in Figure 1, the end receiver of the data is not a wireless node in the wireless network, but a network entity managed by the operator and the tools used by the operator, where the data comes from UE statistical counters and measurements. the

Reference numerals in Figure 1 refer to the following steps:

11. The UE is within the expected coverage of the MBMS. The UE may be receiving MBMS services, or the UE may not be receiving MBMS services. the

12. The UE performs statistical data measurements and maintains statistical counters related to MBMS reception, MBMS service and user experience of MBMS service. the

13. The UE reports statistical measurements and counters to the network. the

14. On the network side, several data post-processing and data conversion processing steps are possible. The radio access network is involved in data post-processing and data conversion in order to make it possible to optimize measurement reports by radio access technology specific compression techniques. the

15. Present the post-processing results to the operator. The result may be a statistical indicator of a combination of measurement results from multiple UEs, or a statistical indicator of a combination of results reported by other nodes, or in a specific time period A statistical indicator for the inner portfolio. In cases of drastic changes, results may be converted into alerts. the

16. Other results of statistical post-processing, such as more detailed geographical information, can be input into support tools, and operators can use support tools for network adjustment and fault diagnosis. the

In the present invention, the UE uses a communication mechanism separate from the MBMS radio bearer or separate from the MBMS system to report statistical measurement results and counters. Specifically, the UC system overlaying the MBMS system can be used to report the results. In particular, this is especially true for MBMS DC systems. In particular, for MC systems, UEs may report results using communication mechanisms related to UC and/or UC services. the

Fig. 2 schematically shows another embodiment of the system for multimedia service transmission and statistics report according to the present invention. the

Figure 2 shows the UE reporting results in different ways. the

As shown in Figure 2, the communication mechanism used by the UE to report the results is separate from the MBMS system. Figure 2 is the same as Figure 1 except that specific details and alternatives are added in steps 23(a,b,c). the

Reference numerals 23a-23c in Fig. 2 refer to the following steps:

23a. The UE may use another unicast-capable wireless network for reporting, eg reporting on another wireless carrier. This replacement is particularly attractive when a DC system is overlaid on a UC network. the

23b. If the MBMS system (MC system) supports it, the UE can use UL resources on the same carrier as the MBMS system. These UL resources may be MBMS-independent UC data transport channels. the

23c. Another non-standardized mechanism, e.g. UE sends a report when accessing the Internet by any means of connectivity. the

When there are alternative measurements and counters, or when there are alternative ways to make/calculate measurements and counters, or when there are alternative ways to report the results, the network entity should control which options will be used. If there are parameters for controlling the above options, the network entity shall be able to determine the setting of the parameters. The UE can propose its recommended options and its settings and provide the network entities with the capabilities of the UE. the

Preferably, the network entity can control UE measurement and counter related to MBMS according to the control information sent by the MBMS carrier. Specifically, the network entity can preferably control MBMS-related UE measurements and counters according to control information not related to control information for MBMS services or sessions. Specifically, the control information can preferably be sent through a conventional control channel of a radio carrier or a conventional control channel for MBMS services, so as to realize that the network entity controls MBMS-related UE measurements and counters. Specifically, the channel may be a normal control channel such as a broadcast control channel (3GPP BCCH) or an MBMS control channel (3GPP MCCH), or the channel may be a dedicated control channel (3GPP DCCH). the

Preferably, the network entity can control UE measurements and counters related to MBMS according to the control information sent by the communication channel instead of the control information sent by the MBMS carrier. Specifically, preferably, the network entity can control MBMS-related UE measurements and counters according to control information that is not related to control information for MBMS services or sessions. Specifically, for MBMS DC deployment, preferably if the wireless network is GSM/EDGE Radio Access Network (GERAN), UMTS Terrestrial Radio Access Network (UTRAN), LTE, CDMA2000, Air Interface Evolution (AIE) , Wireless Fidelity (WiFi), and Worldwide Interoperability for Microwave Access (WiMAX), the control information can be sent through the wireless carrier of the UC wireless network. Specifically, preferably, the control information can be sent through the normal control channel of the UC wireless carrier, or through the normal control channel used for MC MBMS service on the UC wireless carrier. Specifically, the channel may be a normal control channel such as a broadcast control channel (3GPP BCCH) or an MBMS control channel (3GPP MCCH), or the channel may be a dedicated control channel (3GPP DCCH). the

Preferably, the measurement can be triggered by paging or notification to one or several UEs. The control information related to the requested measurement is sent in a paging/announcement message, or the paging/announcement message only triggers the UE to use any of the mechanisms described above to obtain all control information for a particular measurement. the

Fig. 3 schematically shows an embodiment of a system according to the present invention, the system is used for multimedia service transmission, statistics report and user equipment measurement control. the

The UE measurement control shown in Figure 3 can be done in several ways. the

Reference numerals in Fig. 3 refer to the following steps:

31. The operator configures UE statistical measurement options and parameters through the O&M system. The operator can select the control method 33a or 33b according to the situation of use. the

32. The O&M system distributes the above-mentioned control information to the wireless access network. the

33a. UE statistical measurement options and parameters may be sent by the MBMS radio network to the UE when only UEs monitoring MBMS channels are included, or when the MBMS radio network is a UC-capable MC network. Specifically, control information can be sent to UE in the following ways:

a. Common control channels related to radio access technologies, such as broadcast control channels (3GPP: BCCH). the

b. MBMS Control Channel (3GPP: MCCH). the

c. UE dedicated control channel (3GPP: DCCH), only used for MC network configuration. the

d. The application layer control channel is only used for MC network configuration, which is implemented by UC information packet carrying or SMS cell broadcasting. the

e. A paging/announcement message, or a combination of a paging/announcement message and any of the above a-d. the

33b. For the MBMS DC system, when the UE is not currently monitoring the MBMS channel, for example, when it is out of coverage or when the UE is not currently interested (may only perform test transmission or no transmission), it is necessary to set the UE statistical measurement options and parameters Sent to the UE by a non-MBMS network, such as an overlay UC network. the

In particular, control information is sent to the UE in the following ways: 

f. UC common control channel related to radio access technology, such as broadcast control channel (3GPP: BCCH). the

g.MC MBMS control channel, when the UC network supports MBMS MC (3GPP: MCCH). the

h. UC UE dedicated control channel (3GPP: DCCH). the

i. Application layer control channel, which is implemented by UC information packet bearer or SMS cell broadcast. the

j. A paging/announcement message, or a combination of the paging/announcement message and any one of the a-d methods in the above-mentioned step 32a and the f-i methods in this step 33b. the

It should be pointed out that in the application where the UE uses multicast or broadcast services, it is required that the UE can respond to the network. And in the above application where the UE uses multicast or broadcast services, a mechanism similar to that used in statistical measurement reporting is used. the

Apart from statistical data measurement, any interactive TV application such as voting, and UE responsible for bearer layer reconfiguration for MBMS, can be handled in a similar manner as described above. the

The concept of UE statistics measurement can also be applied to UC systems and services. the

According to the invention, the UE shall perform performance related measurements and maintain counters related to user experience and radio transmission reception of MBMS transmissions and report the corresponding results to the network entity. In this way, problems can be detected, measured and analyzed, and corrected in cases where the network itself cannot maintain statistics for the MBMS DC, and in cases where the MBMS MC does not employ special programs to maintain statistics and counters in the network / Tuning of radio access networks where detection, measurement and analysis issues are related to user experience and reception of transmissions. the

According to the present invention, as described above, a network entity can control whether a single receiver/transmitter UE needs to report. In this way, overall, the impact on the MBMS application of the measurement reports can be minimized. First, the network entity tries to obtain the required measurement reports from the duplex receiver/transmitter UE, i.e. the user equipment operates in duplex communication mode, which means that the user equipment can receive and transmit signals at the same time, and only when receiving and transmitting When the transmitted signal is insufficient, the single receiver/transmitter UE needs to report. the

According to the present invention, the UE statistical measurement report can be delayed, ie the UE does not need to send the measurement report immediately when the measurement result is available. Further, reporting of statistical measurements should be timed when the appropriate opportunity arises. In this way, for a single receiver/transmitter UE, the MBMS application for measurement reports can be made e.g. minimal impact. Therefore, the measurement report can also be sent in the same MBMS reception interruption interval, compared with sending the measurement report not related to the UC paging response, the impact on the user as a whole is smaller. In this way, further, the UE statistical measurement report is less dependent on the coverage of the UC network. If the coverage of the UC network is poor, the UE may wait until it moves into better coverage to report. the

Specifically, there are many possible situations, such as user activity when the user switches channels, when the user turns off reception, when the user is muted, etc. the

In practice, statistics measurement reporting can be delayed for a long time in cases where there is a lot of use, for example, for routine performance monitoring. For these cases above, statistical data measurement reporting can be done at the end of the session or when the user turns off the UE. For a single receiver/transmitter UE, this approach minimizes the impact on the MBMS application of measurement reporting to zero. In fact, UEs without WAN wireless uplink, or UEs that are completely out of UL coverage, can report statistical measurements when they get IP connectivity, where the UE is via cable, bluetooth, infrared or similar technology to make IP connections. the

For the case of delayed measurement reporting, the effective measurement time must be defined, and how the UE should manage its internal data storage space must be defined. the

Use cases such as performance monitoring or fault diagnosis, and the operation of post-processing systems should determine the maximum delay time for delayed reporting. The last to report deadline may be configured by the network in the UE, eg the last to report deadline is signaled together with other measurement control information. When the deadline for reporting is exceeded, the UE may discard the measurement results and not report the measurement results. In this way, the UE can be prevented from sending outdated reports that are not used by the network (but discarded), thereby reducing the load generated by useless reports and the use of storage space in the UE. the

When the storage space of the UE is exhausted and more data storage space is needed to store the latest measured data, the oldest stored measurement report data or the data closest to the termination time in time can be overwritten. In this way, the statistical measurement report data in the UE can be reported as much as possible, and will not be deleted due to lack of reporting opportunities within the required time limit. the

Further, the network entity shall control whether the measurement report shall be sent when the maximum allowed delay is approached, or whether the measurement report shall be discarded if there is no suitable sending opportunity, here disregarding the interference of other functions/applications. For some use cases, such as when troubleshooting, and such as when there are not many UEs running, the reporting of statistics needs to be enhanced to ensure that there is data from a sufficient number of UEs, combined with a short maximum delay time. the

Note that for statistics/counters/measurements, the radio access network is not the primary recipient of the measurement results. Primary receivers can be replaced by network entities and O&M post-processing systems. the

In order to deal with the scheme of MBMS DC, the reporting mechanism can adopt various UC radio access technologies, such as GERAN, UTRAN, 3GPP LTE, WiMax, etc. the

Therefore, in order to make the above practically possible, it is important that the impact of supporting UE statistics and measurement reporting functions on the implementation of the radio access network must be minimal. the

In addition, the number of data transformations that need to be performed needs to be minimized in order to enable the O&M statistics post-processing system to process the measurement data from the UE. the
