Description

Service transmission method and apparatus of the present application claims ¹ to March 23, 2011 submitted to the China Patent Office Application No. 201110070864.7, entitled priority to Chinese patent application "Method and apparatus for transmission of business" in its entirety by The citations are incorporated herein by reference. The present invention relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for service transmission. BACKGROUND With the continuous introduction of intelligent terminals and the continuous enhancement of wireless network transmission capabilities, the traffic of video services in wireless networks has experienced explosive growth, accounting for about 30% of network traffic, which has become the T0P2 service in current wireless networks. The quality of service of wireless video services has become an important indicator of the level of wireless network operations.

 Currently, there are two major categories of wireless video services: one is web-based video services, and the other is dedicated server-based real-time video services. Web browsing-based video services deliver video services over standard HTTP (HyperText Transfer Protocol) servers, such as YouTube (which is an Internet site that provides users with services such as watching and sharing video clips), BELL HLS ( BELL HTTP Live Streamin, Bell HTTP Live Streaming) Live live video. In this video service mode, a dedicated TCP (Transmission Control Protocol) connection is established between the client and the server; the client sends an HTTP request message to the server through a dedicated TCP connection, requesting the server to transmit the video file; The dedicated TCP connection sends an HTTP response message, and the video data is transmitted to the client, that is, each user separately establishes a bearer for file transmission. The real-time video service based on the dedicated server is a real-time video broadcast through a dedicated server such as RTP (Real Time Transport Protocol), RTMP (Rea Time Messaging Protocol), etc. During the live broadcast of the video service, The video server always obtains the latest video clips, encodes the appropriate media format, and finally assembles into different transport layer data packets, and sends them to the client, that is, the network allocates independent transmission resources for each live video user, and establishes a dedicated bearer.

In the process of implementing the above-mentioned wireless video service, the inventors found that at least the following problems exist in the prior art: The network allocates an independent transmission resource for each service request. For terminals in the same cell, this allocation Ways have formed a huge waste of air interface resources <

The user allocates the same transport bearer and performs a shared transport. The overall architecture of end-to-end service propagation based on the same transmission is shown in Figure 1.

As shown in Figure 1, the service transmission on the network side can still comply with the existing service transmission mode service, that is, the service is separately transmitted for each terminal through dedicated resources. The ISP (Internet Service Provider) server can be an HLS (HTTP Live Streaming) video server or a YouTube video server; depending on the wireless system, CN (Core Network) can be of different types. Service network element, such as GSM (Global System for Mobi le Communicat ions) or UMTS (Serva GPRS Support Node, J! GPRS support node) Serving with GGSN (Gateway GPRS Support Node), LTE (Long Term Evoluting, 3GPP Long Term Evolution) system GW (Serving GateWay, Service Gateway) and PDN GW. The service identification module PI on the RAN side performs a service identification operation on the service delivered by the ISP server. Depending on the radio system, the RAN network elements that perform service identification are also different, such as the BSC (Base Stat Analyzer) of the GSM system, and the RNC (Radio Network Controller) of the UMTS system. ), an eNodeB (evolved Node B, evolved base station) of the LTE system, or the like.

 The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

 An embodiment of the present invention provides a method for service transmission. As shown in FIG. 2, the method may include:

101. The radio access network element sets the user performing the same service in the same user group.

 The method for the radio access network element to set the user to perform the same service in the same user group may be implemented by, but not limited to, the following method, where the method includes: the radio access network element according to the service request of the user Or the service is identified according to the identification result, and the users performing the same service are set in the same user group; or the users performing the same service are set in the same user group according to the core network trigger; wherein, the core network can pass multiple The mode triggering may be, for example, the radio access network element receiving the group transmission request sent by the core network, and setting the user performing the same service in the same user group according to the group transmission request, which is not used in this embodiment. Make a limit.

 The radio access network elements are also different according to the radio system standard, such as the BSC of the GSM system, the RNC of the UMTS system, and the eNodeB of the LTE system.

 102. The radio access network element allocates the same group transmission resource to a user included in the one user group. The same group transmission resource may be, but not limited to, a group transmission channel resource of a transmission service. Further, when the radio access network element allocates the group of transmission resources, the radio access network element may also perform the QoS (Quality of Service) requirement for each user in the user group. The users included in the user group are allocated the same group transmission resource, but the embodiment of the present invention does not limit this.

 103. The radio access network element broadcasts a service to the user by using the group transmission resource.

In the embodiment of the present invention, the radio access network element sets the users currently performing the same service in the same user group, and allocates the same group transmission resource to the users included in the one user group, and uses the group transmission resource. Xiangshou The user broadcast service can solve the problem of repeated resource allocation, and can improve the utilization of air interface resources in the transmission process of the wireless video service.

 Another embodiment of the present invention provides a method for service transmission. As shown in FIG. 3, the method includes: 201. A radio access network element sets a user performing the same service in a same user group.

 The method for the radio access network element to set the user to perform the same service in the same user group may be implemented by, but not limited to, the following method, where the method includes: the radio access network element according to the service request or service of the user Identifying the service performed by the current user, and setting the user performing the same service in the same user group according to the recognition result; or setting the user of the same service according to the trigger of the core network by the wireless access network element In the same user group.

 It should be noted that, when the radio access network element sets the users performing the same service in the same user group, if there are multiple different services, multiple different user groups are obtained; When users allocate the same group transmission resources, they need to allocate different transmission resources for different user groups.

 202. Determine, according to a predetermined policy, whether to initiate a group transmission mode, where the group transmission mode allocates a transmission mode of the same transmission resource to multiple users. If the group transmission mode is determined according to the predetermined policy, step 203 may be performed; According to the predetermined policy, it is determined that the group transmission mode is not activated, and the transmission resource may be allocated to the user according to an existing service transmission manner.

 For example, the allocation of the transmission resource to the user according to the existing service transmission manner may be: if the user has been allocated a separate transmission resource, the allocated transmission resource is used to transmit the service for the user, if not yet When the user allocates a separate transmission resource, the user is allocated a separate transmission resource, and the newly allocated transmission resource is used to transmit the service for the user.

The predetermined policy may include: according to the network management configuration, for example, for the popular video service, the group transmission mode may be started at the beginning, regardless of how many users are watching under the coverage of the wireless access network element, such as football during the World Cup. The live video service; or, according to the core network trigger, the group transmission directly established when the service is established must be triggered by the core network. The triggering according to the core network is specifically as follows: The core network sends a group transmission request, if the RAN side does not establish a multicast channel for the current multicast service, dynamically allocates a new group transmission channel, and directly assigns the user if it is allocated. On the group channel; or, the group transmission mode can be determined according to the number of users viewing the same video. For example, when the number of users viewing the same video reaches the corresponding preset threshold, the group transmission can be started. The input mode, wherein the preset threshold can be set according to actual needs. It should be noted that, in this case, the number of users viewing the same video under the coverage of the wireless network element may be determined by using a DPI (Deep Packet Inspection) technology or other data packet or data flow detection technology. The specific technology used to determine the number of users viewing the same video covered by the wireless network element is not limited. The DPI technology is an application layer-based traffic detection and control technology, when IP data packets, TCP (Transmitation Control Protocol) or UDP (User Datagram Protocol) data streams Through the bandwidth management system based on DPI technology, the system reorganizes the application layer information in the Layer 7 protocol of the 0SI (Open System Interconnect) by deeply reading the contents of the IP packet payload, thereby obtaining the entire application. The content of the program, and then the traffic is shaped according to the system-defined management policy.

 203. Allocate the same group transmission resource to the user included in the user group according to the QoS requirement of the same service performed by the user included in the one user group.

 The same group transmission resource may be, but not limited to, a group transmission channel resource for transmitting a service, for example, a wireless network temporary identifier or the like may also be included. After the radio access network element allocates the same channel resource to the user included in the user group, the user in the user group can use the group of transmission channel resources to perform the same service transmission. Specifically, the group configuration command corresponding to the allocated group transmission channel resource may be used to indicate that the user included in the user group accesses the group transmission channel resource; specifically, the group included in the user group is included. The user sends an assignment message indicating that the user accesses the group transport channel resource, so that the user in the user group uses the set of transport channel resources to perform the transmission of the same service. The radio access network element may send the group configuration command to each user included in the user group; after receiving the group configuration command, each user accesses the group transmission channel according to the group configuration command. .

 204. When receiving multiple services allocated by the Internet Service Provider (ISP) server for the user group, select one of the multiple services as the same service of the user included in the user group.

 It should be noted that, when receiving the service request sent by the user included in the user group, the ISP server allocates a service to each user included in the user group and sends the service to the corresponding user. The allocation mechanism causes the radio access network element to receive a plurality of services allocated by the ISP server for the user group.

When one of the multiple services is selected as the same service of the user included in the user group, one of the multiple services may be selected as the user included in the user group. Same industry The embodiment of the present invention may also be used to select the same service as the same service of the user included in the user group according to the current network status and the RRM algorithm. This is not restricted, and the user can select it according to the needs.

 205. Broadcast the same service to the user included in the user group by using the group transport channel resource. Further, in the embodiment of the present invention, in a process in which the radio access network element broadcasts a service to the user by using the group transmission resource, the radio access network element may detect a service execution status of the user in real time, if monitoring When a new user needs to join the user group or the user in the user group ends the service, the embodiment of the present invention further includes the following methods:

 If it is detected that the new user performs the same service as the user group, the new user is assigned the same group transmission resource, and the assigned group transmission resource is used to send the service to the new user. It should be noted that, due to factors such as the ability of the new user to perform services or the link quality, the group transmission channel of the user group needs to be reconfigured, and the radio access network element joins the new user to the location. After the user group is further included, determining whether to re-allocate the same group transmission resource for the user included in the user group according to the service capability or link quality of the new user;

 If it is determined that the user included in the user group is reassigned the same group transmission resource, the user included in the user group is reassigned the same group transmission resource, and is sent to each user included in the user group. a group transmission resource reconfiguration command, instructing the user to access the reassigned group transmission resource, to broadcast the service to the user by using the reconfigured same group transmission resource; or

 If it is determined that the same group transmission resource is not reassigned to the user included in the user group, performing the same group transmission resource for the new user, and transmitting the service to the new user by using the assigned group transmission resource .

 If it is detected that the user included in the user group terminates execution of the same service, the group transmission resource assigned to the user that terminates the execution of the same service is revoked.

 If it is detected that all users included in the user group terminate the execution of the same service, the group transmission resource allocated for the user group is released.

If it is detected that the service capability or the link quality of any user included in the user group changes, determining whether to reassign the same group to the user included in the user group according to the changed service capability or link quality. Transmission resource; if it is determined that the user included in the user group is reassigned the same group transmission resource, it is the user The user included in the group reassigns the same group transmission resource, and sends a group transmission resource reconfiguration command to each user included in the user group, indicating that the user accesses the reassigned group transmission resource, so as to utilize The reconfigured same group transmission resource broadcasts traffic to the user.

 Further, it should be noted that, in the process of performing service transmission, the user may not only transmit the same service, for example, when the user also needs to perform transmission of other non-identical services, the method may further include:

 While allocating the same group transmission resource for the same service, the non-identity service may also be allocated a dedicated transmission resource; and the non-identical service is sent to the user by using the dedicated transmission resource. When the dedicated transmission resource is allocated to the non-identical service, the dedicated transmission resource may be allocated to the non-identical service according to the QoS requirement of the non-identical transmission service, but the embodiment of the present invention does not limit this.

 In the embodiment of the present invention, the users currently performing the same service are set in the same user group, and the users included in the user group are allocated the same group transmission resource, and the group transmission resource is used to broadcast to the user. The service can solve the problem of the repeated allocation of resources, and can improve the utilization of the air interface resources in the transmission process of the wireless video service. In the embodiment of the present invention, the radio access network element in the downlink direction is based on the worst link quality. Multiple users included in the user group transmit the same service, which can save more downlink power resources.

 In the embodiment of the present invention, before the radio access network element allocates the same group transmission resource to the user included in the one user group, determining whether to start the group transmission mode according to a predetermined policy, when determining to start the group transmission mode, The user is allocated the same group transmission resource according to the user included in the user group, and then the service is broadcast to the user by using the group transmission resource, so that the application of the same service transmission is flexible.

 Moreover, in the embodiment of the present invention, when a service performed by a new user is the same as a service performed by the user group, the group of transmission resources may be assigned to the new user, and the service is sent to the new user on the group transmission channel. Therefore, the utilization of the air interface resource of the wireless service transmission is further improved, and as the number of users increases, the resource utilization rate of the group transmission mechanism increases linearly.

Another embodiment of the present invention provides a method for implementing the same service transmission based on a universal browser (such as IE) or a terminal embedded browser (such as a safar i browser of an i Phone terminal). The browser is generally used to implement the transmission of the video stream based on the HTTP protocol, such as HTTP real-time streaming (HTTP L ve S treaming). In this embodiment, the video service is taken as an example for description. In this embodiment, the HSDPA transmission mode is taken as an example to describe a group transmission channel establishment process of a video service. In the HSDPA transmission mode group transmission mechanism, the RAN can identify the video service in the serving cell, and according to The predetermined policy decision initiates a group transfer mechanism to switch the users included in the user group to the same HSDPA transmission resource. As shown in FIG. 4, the method may include:

 301. The RAN monitors the video service triggered by the user, sets the user who performs the same video service in the same user group, and determines whether to initiate the group transmission mode according to a predetermined policy.

 The RAN sets the user who performs the same video service in the same user group, and can be implemented by, but not limited to, the following method. The method includes: the RAN monitors a video service triggered by the user, according to the user. The service request or service identifies the service performed by the current user, and sets the user who currently performs the same video service in the same user group according to the identification result; or the RAN performs the same video service according to the trigger of the core network. Users are set in the same user group.

 The predetermined policy may include: according to the network management configuration, for example, for the popular video service, the group transmission mode may be started at the beginning, regardless of how many users are watching under the coverage of the wireless access network element, such as during the World Cup. The live broadcast video service may be determined according to the number of users viewing the same video. For example, when the number of users viewing the same video reaches a preset threshold, the group transmission mode may be started, where The preset threshold can be set according to actual needs. It should be noted that, in this case, the number of users viewing the same video under the coverage of the wireless network element may be determined by using the DPI technology or other data packet or data flow detection technology. The number of users who are viewing the same video is not limited; or is triggered by the core network. For a detailed description of the triggering by the core network, refer to the corresponding description in the embodiment 2, and the embodiment of the present invention will not be repeated here. .

 302. When the RAN determines to start the group transmission mode according to the predetermined policy, allocate, for the user included in the user group, the same group transmission resource based on the HSDPA transmission mode, where the group transmission resource includes at least a group transmission channel resource, according to the The group transmission channel resource setting group configuration command is used to indicate that the user included in the user group accesses the group transmission channel resource, and sends an assignment message to the user to notify the user to access the group transmission channel resource. Transmitting the same service through the group of transmission channel resources.

The RAN may allocate HSDPA group transmission resources to users in the user group according to the HSDPA transmission mode and the QoS requirements of the current video service of the user in the user group, and the transmission resource may be a group H-RNTI (HS- DSCH Rad io Network Temporary Ident I ty, HS-DSCH (High-Speed Downl Ink Shared Channel) Wireless Network Temporary Identifier), HS-SCCH (High-Speed Shared) Control Channel, high-speed shared control channel) group listening channel, uplink control channel HS-PDCCH (High-Speed Dedicated Physical Control Channel), DPCH (Dedicated Physical Channel) channel, etc., for example, Specifically, it can be:

 If the user performs only the same video service, the RAN can schedule the same group HS-DPDCH (High-Speed Dedicated Physical) for the users included in the user group according to the QoS requirements of the current video service of the user in the user group. Data Channel, a high-speed dedicated physical data channel) channel used to transmit the same video data.

 Further, in the downlink direction, the RAN may allocate the same group HS-SCCH (High-Speed Shared Control Channel) as a listening channel for all users included in the user group, for transmitting the group HS-DPDCH channel. Scheduling information. It should be noted that, if the RAN load is light, in the downlink direction, the RAN may also allocate an independent HS-SCCH to all users included in the user group as a proprietary listening channel for transmitting group HS-DPDCH channel scheduling information. ; Assign a dedicated H-RNTI for scrambling the proprietary HS-SCCH channel. When performing service transmission, the respective dedicated control channels of the users in the user group send the same scheduling information for all users included in the user group, and schedule an appropriate group HS-DPCHCH channel for the user group.

 Further, in the uplink direction, the RAN may allocate an independent HS-DPCCH channel for each user, and transmit the unique HARQ (Hybrid Automatic Repeat Request) process receiving information and link quality information. In addition, the RAN may also allocate a separate companion DPCH channel for each user to provide a transmit power reference for the HS-DPCCH channel and the HS-SCCH channel.

 If the user performs other non-identical services while performing the same video service, such as continuing to browse the webpage where the video service is located, in this scenario, the MN can allocate the same group of transmission resources to the user group, and the RAN can also Allocating the non-identical service by allocating a dedicated transmission resource for the non-identical service.

 When the RAN allocates dedicated transmission resources for non-identical services, it may allocate HSDPA (High-Speed Downlink Packet Access) transmission mode or DCH (Dedicated Channel) based on user capabilities. Channel) A dedicated transmission resource for the transmission mode.

The allocating the dedicated transmission resource based on the DCH transmission mode may include: the RAN assigns an independent dedicated DPCH channel to the user for transmitting the non-identical service according to the QoS requirement of the non-identical service. And, at this time, the RAN can provide a power reference for the HSDPA transmission of the same service through the dedicated DPCH channel, replacing the original companion DPCH. channel.

 The allocating the dedicated transmission resource based on the HSDPA transmission mode may include: the RAN allocates the HS-SCCH as the listening channel for the non-identical service, and is used to transmit the user-specific scheduling information; and allocate the dedicated H-RNTI for the user. The intercepted HS-SCCH channel is scrambled; according to the QoS requirements of the non-identical service, the RAN schedules a suitable dedicated HS-DPCHCH transmission resource for the terminal to transmit the non-identical service. The non-identical service of the user may still apply the foregoing HS-DPCCH channel feedback HARQ reception information and link quality information, and apply the foregoing independent companion DPCH channel to provide a transmission power reference of the HS-DPCCH channel and the HS-SCCH channel. It should be noted that, for the HSDPA group transmission mode of the independent HS-SCCH channel and the H-RNTI identifier, the HS-SCCH channel may be a non-identical service and the same service scheduling proprietary HS-PDSCH transmission in a time division multiplexing manner. The resource and group HS-PDSCH transmission resources are fully compatible with the existing HSDPA transmission mechanism. For the HSDPA group transmission mode sharing the HS-SCCH channel and the H-RNTI identifier, the RNC needs to allocate the group H-RNTI and the dedicated H to the terminal at the same time. - RNTI. In this scenario, the HSDPA receiving capability of the terminal needs to be extended.

 303. After receiving the assignment message, the user accesses the group transmission channel, and returns a response to the RAN. The user included in the user group sends an HTTP GET request to the corresponding ISP server to request the latest. Playlist file or ts video file.

 305. Receive an latest playlist file or a ts video file sent by the ISP server for each user included in the user group, and the latest playlist file or the ts video file may be returned by using an HTTP RESPONSE message.

 It should be noted that since the same transmission mechanism does not modify the existing network architecture, the server will return an HTTP RESPONSE message for each user. Each HTTP RESPONSE message carries a playlist file or a ts file requested by the user.

 306. The RAN selects, as the HTTP RESPONSE message of the group, one of the multiple HTTP RESPONSE messages sent by the receiving ISP server, that is, the same video service of the user included in the user group.

In addition, when the RAN receives the multiple HTTP RESPONSE messages from the RANPONSE message, the RAN may also select an HTTP RESPONSE message as the HTTP RESPONSE message of the group according to the current network status and its own RRM algorithm. No restrictions are imposed. 307. The RAN broadcasts the selected HTTP RESPONSE message by using a group transport channel resource, where the HTTP RESPONSE message carries a latest playlist file or a ts video file.

 The RAN broadcasts the selected HTTP RESPONSE message by using the group transmission resource, including: transmitting video service scheduling information on the HS-SCCH channel that the user group listens, and transmitting the selected information on the scheduled group HS-DSCH channel. HTTP RESPONSE message.

 Optionally, in the step 302 of the embodiment of the present invention, when the RAN allocates the same group of transmission resources to the user included in the user group, the RAN may also be performed according to the DCH transmission mode, and the RAN is a user group different from the HSDPA-based transmission mode. The included user allocates the same group transmission resource to the DPCH code channel or the like, and transmits the selected HTTP RESPONSE message on the group DPCH code channel that the user group listens when transmitting the video resource on the group transmission channel. The RAN allocates a group to the user group in the user group according to the DCH transmission mode, which may be:

 If the user only performs the same video service, in this scenario, the same group DPCH code channel is used to transmit the same video data. At this time, the RAN allocates the same group DPCH code channel to the users included in the user group, and transmits the same video data. At the same time, the RAN allocates a dedicated DPCCH channel independently for each user, and transmits control information such as pilot-specific pilot (PILOT), TFCI (Transport Format Combination Indicator), and power control commands. Specifically, as shown in FIG. 5, a specific configuration of a group DPCH transmission channel in the downlink direction is given: where the same group DPCH code channel of the user group only contains the data part DPDCH channel of the DPCH channel; the user-specific DPCH code channel , only the control part DPCCH channel of the DPCH channel is transmitted.

 If the user performs other non-identical services while performing the same video service, such as continuing to browse the webpage where the video service is located, in this scenario, the RAN allocates the same group of transmission resources to the users included in the user group. The RAN also needs to allocate the dedicated transmission resource for the non-identical service to transmit the non-identical service.

 When the RAN allocates a dedicated transmission resource for the non-identical service, the dedicated transmission resource based on the HSDPA transmission mode or the DCH transmission mode may be allocated according to the user capability.

The allocation of the dedicated transmission resource based on the HSDPA transmission mode includes: the RAN allocates the HS-SCCH as a listening channel for the user to transmit the user-specific scheduling information; and allocates the dedicated H-RNTI to the HS-SCCH for the user to listen to. The channel is scrambled. According to the QoS requirement of the non-identical service, the RAN schedules a suitable dedicated HS-DPDCH transmission resource for the non-identical service, and transmits a corresponding non-identical service. In the uplink direction, the RAN allocates dedicated HS-DPCCH channel feedback HARQ reception information and link quality information to the user. At this time, the RAN is no longer for each user group. A user allocates an independent companion DPCH channel for providing a transmit power reference for the HS-DPCCH channel and the HS-SCCH channel, but provides a power reference for HSDPA transmission through the aforementioned dedicated DPCH code channel.

 The allocation of the dedicated transmission resource based on the DCH transmission mode includes: the RAN further, according to the QoS requirement of the non-identical service, assigning an independent dedicated DPCH code channel to the non-identical service, for transmitting the non-identical service. In the channel coding function of the existing WCDMA system, the data of the same CCTrCH (Coded Composite Transport Channe 1, Coding and Synchronization Transport Channel) channel needs to be second interleaved before actually mapping to the physical channel. Therefore, in order to ensure that the same video service and the user-specific service can be transmitted independently, the group transmission mechanism of the service concurrent scenario requires that the terminal user can support the service of the two CCCHCH channels of the DCH type at the same time. At this time, the RAN allocates two types of DCH channels to the application terminal: a dedicated DCH channel and a group DCH channel, which is used to transmit UE-specific services; and a group DCH channel is used to transmit the same video. Each type of DCH channel is mapped to a different CCTrCH channel and a DPCH code channel, respectively. The same group DPCH code channel of the user group only contains the data part DPDCH channel of the DPCH channel; the data part of the DPCH code channel corresponding to the non-same service channel transmits the corresponding non-identical service, and the control part of the proprietary DPCH code channel DPCCH The channel transmits control information such as terminal-specific pilots PIL0T, TFCI, and power control commands.

 Optionally, in step 302 of the embodiment of the present invention, the RAN may also be based on FACH (Forward Access)
