Description

Method for accessing service guide announcement channel, terminal and server

technical field

The invention relates to the technical field of broadcast and multicast services, in particular to a method for accessing a service guide announcement channel, a terminal, and a broadcast and multicast service server.

Background technique

In Multimedia Broadcast Multicast Service (MBMS, Multimedia Broadcast Multicast Service), it is necessary to implement region-based broadcast services, that is, terminals need to receive different broadcasts in different geographic regions.

In the MBMS area-based broadcast service, the terminal needs to receive the service guide information of the area where it is located. Since the broadcast content is different in different areas, the service guide information that the terminal needs to receive in different areas is also different.

At the same time, since the terminal accesses the broadcast bearer channel through the temporary mobile group identity (TMGI, Temporary Mobile Group Identity) of the MBMS broadcast bearer channel, and the MBMS broadcast network broadcasts and sends service guide information on the service guide announcement channel, therefore In order to obtain service guide information, the terminal needs to access the service guide announcement channel; and in order to access the service guide announcement channel, the terminal needs to know the TMGI for accessing the service guide announcement channel.

In addition, as mentioned above, the terminal needs to receive different service guide information in different areas, so the terminal needs to know the TMGI of the service guide announcement channel in the area where it is currently located.

In the prior art, when a terminal roams to a certain area, there are two schemes for obtaining the TMGI of the service guide announcement channel of the area:

Solution 1: Preset the TMGI information of the service guide announcement channel of each area on the terminal, and when the terminal roams to a certain area, access the service guide announcement channel of the area based on the preset TMGI information. This solution requires the terminal to embed the TMGI information of the service guide announcement channel for each area. If the area granularity is small, the terminal needs to embed a large amount of information, making this solution difficult to be adopted in practical applications. And adopting this solution requires the terminal to have the ability to know the area where it is currently located.

Solution 2: Use the same bearer channel as the service guide announcement channel in all areas to broadcast and send service guide information. That is, the TMGI of the service guide announcement channel in all areas is the same, so when the terminal roams to a certain area, it can access the service guide announcement channel of the area based on the unified TMGI information. Since the service guide information broadcast in different areas is different, and the same bearer channel requires the same session control, so adopting this solution needs to implement different service guide information broadcast to different areas in the same session. This solution needs to modify the standard protocol, and needs to modify the wireless network equipment to support it.

To sum up, in order to enable the terminal to correctly access the corresponding service guide announcement channel in different areas, in the prior art solutions, it may be necessary to build the TMGI information of the service guide announcement channel for each area in the terminal, and The terminal needs to have the ability to know the area where it is currently located; or it needs to modify the wireless network equipment to support it. That is, the solution in the prior art either has the problem of increasing the complexity of the terminal equipment, or has the problem of needing to modify the wireless network equipment.

Detailed ways

The scheme for accessing the service guide announcement channel proposed by the embodiment of the present invention is as follows: the network side and the terminal side pre-agreed on the structure of the service guide announcement channel identifier, and the network side assigns an identifier to each bearer channel based on the agreed structure, and broadcasts and sends each bearer channel The identification of the channel: based on the agreed structure, the terminal side selects the identification of the service guide announcement channel conforming to the agreed structure from the received identifications of the bearer channels, and accesses the service guide announcement channel.

The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

Figure 1 is a flow chart of a method for accessing a service guide announcement channel proposed by an embodiment of the present invention, and the specific process is described as follows:

Step 11: Based on the preset structure of the service guide announcement channel identifier, the network side assigns an identifier with the preset structure to the service guide announcement channel, and assigns an identifier that does not have the preset structure to other bearer channels except the service guide announcement channel. logo;

The MBMS service server and the terminal agree on the structure of the service guide announcement channel identifier. The MBMS service server specifies a channel identifier with the agreed structure for the service guide announcement channel of each MBMS service domain according to the agreed structure, and assigns a channel identifier with the agreed structure for each MBMS service domain. The bearer channels other than the channel announced in the service guide specify channel identifiers that do not have the agreed structure.

For example, the MBMS service server and the terminal agree on an identification prefix used only for the service guide announcement channel. When a certain value is agreed upon as the identification prefix of the service guide announcement channel, other service bearer channels will not be able to use this prefix to identify the channel. Assuming that the prefix of the service guide announcement channel identifier is agreed to be "1", and the bearer channel identifier is 3 bytes, the MBMS service server can assign identifiers "101", "102" and "103" to the service guide announcement channel, and other bearer channel identifiers The channel ID can be "201", "202", "304" and so on.

In the following embodiments of the present invention, the service guide announcement channel identifier is illustrated by taking an identifier with a preset prefix as an example. Of course, the identifier of the service guide announcement channel can also be an identifier with a preset suffix, or a preset prefix and a preset suffix identification, etc. For example, the MBMS service server and the terminal agree on an identification suffix that is only used by the service guide announcement channel. When a certain value is agreed upon as the identification suffix of the service guide announcement channel, other service bearer channels cannot use this suffix to identify the channel. Assuming that the suffix of the service guide announcement channel identifier is agreed to be "12", and the bearer channel identifier is 3 bytes, then the MBMS service server can assign identifiers "112", "212" and "312" to the service guide announcement channel, and other bearer channel identifiers The channel ID can be "101", "202", "304" and so on. For another example, the MBMS service server and the terminal agree on the identification prefix and suffix used only for the service guide announcement channel. When a certain value is agreed to be the identification prefix and suffix of the service guide announcement channel, other service bearer channels will not be able to use this A combination of prefix and suffix to identify a channel. Assuming that the prefix of the service guide announcement channel identifier is agreed to be 1, the suffix is agreed to be "12", and the bearer channel identifier is 5 bytes, then the MBMS service server can assign identifiers "10012", "10112", "11212" to the service guide announcement channel ", etc., and the identifiers of other bearer channels may be "10111", "20012", "30144" and so on.

Step 12, the network side broadcasts and sends the identification of each bearer channel including the service guide announcement channel;

The structure of the MBMS system is shown in Figure 2. When the MBMS service server needs to broadcast service guide information to a certain MBMS service area, it first specifies a service guide announcement channel for a certain MBMS service area, that is, naming the service guide announcement channel as agreed Then initiate a session start message to establish a service announcement channel, and carry the named service guide announcement channel identifier and the corresponding multicast address and port number of the service guide announcement channel in the session start message. The process of establishing a session is shown in Figure 3, and the specific process is described as follows:

Step S31: the broadcast multicast service center (BM-SC) sends a session start request message (MBMSSession Start Request) to the gateway GPRS support node (GGSN, Gateway GPRS SupportNode); after GGSN receives the session start request message, according to the session in the message attributes, establish an MBMS bearer context, and send back a session establishment request response message (MBMS SessionStart Response) to the BM-SC; then the GGSN will use the Serving GPRS Support Node (SGSN, Serving GPRS Support Node) list and business information in the session start request message Scope (SA, Service Area) parameter, initiate and establish corresponding GPRS Tunneling Protocol (GTP, GPRS Tunneling Protocol) tunnel, and session start request message (MBMS Session Start Request) is sent to all required SGSNs.

Step S32: After receiving the session request message, the SGSN creates the MBMS bearer context, and returns the GTP tunnel parameters to the GGSN through the session establishment request response message (MBMS Session Start Response); , Radio NetworkController) sends a session start request message (MBMS Session Start Request);

Step S33: After the RNC receives the session request message, it sends back a session establishment request response message (MBMS Session Start Response) to the SGSN, and writes the MBMS bearer information into the multimedia broadcast multicast point-to-multipoint control channel (MCCH, MBMS Point-to -Multipoint Control Channel), for the terminal to read; the MBMS bearer information includes identification information of each bearer channel.

Step S34: RNC establishes necessary radio resources (RAN ResourceSetup) for MBMS bearer.

As described in step S33, in the embodiment of the present invention, it is illustrated by taking the network side broadcasting and sending the identification of each bearer channel including the service guide announcement channel through the MCCH channel as an example. Certainly, the identification of each bearer channel may also be broadcasted to the terminal side through other channels.

A method for accessing a service guide announcement channel proposed by an embodiment of the present invention will be introduced below with reference to FIG. 1 .

Step 13: Based on the preset structure of service guide announcement channel identifiers, the terminal side selects the identifiers of service guide announcement channels with the preset structure from the received identifiers of bearer channels;

When the terminal roams to an MBMS service area, it reads a list of all broadcast bearer channel IDs from the MCCH channel, and uses the channel IDs that satisfy the pre-agreed prefixes as the service guide to announce the channel IDs according to the pre-agreed prefix.

Step 14, based on the screened identifier, the terminal side accesses the service guide announcement channel;

Step 15, after the terminal side accesses the service guide announcement channel, obtains the service guide information broadcast and sent by the network side on the service guide announcement channel;

After generating corresponding service guide information according to the service information, the network side broadcasts and sends the service guide information on the service guide announcement channel with the specified identifier.

After the terminal side accesses the service guide to announce the channel, it uses the corresponding multicast address and port number (the terminal can have a built-in service guide to announce the corresponding multicast address and port number of the channel, and the service guide in different regions announces the corresponding multicast address and port number of the channel. number can be the same) to read the service guide data stream to obtain service guide information.

Step 16, when the terminal side fails to obtain the service guide information on the service guide announcement channel, request the service guide information from the network side in a point-to-point manner;

When the terminal cannot obtain the service guide from the service guide announcement channel, the terminal connects to the General Packet Radio Service (GPRS, General Packet Radio Service) network and requests the service guide in a point-to-point manner.

In the following, a specific embodiment is used to illustrate the solution of the present invention. In this embodiment, the service guide announcement channel identifier is illustrated by taking an identifier with a preset prefix as an example; the network side broadcasts and sends the identifiers of each bearer channel through the MCCH channel As an example to illustrate.

FIG. 4 is a schematic diagram of the specific flow of the network side in the method for accessing the service guide announcement channel proposed in Embodiment 1 of the present invention. The flow is described as follows:

Step 41, the MBMS terminal and the MBMS service server agree on the rules for the identification of the service guide announcement channel;

If the prefix of the service guide announcement channel identification is agreed to be "1", other service bearer channels will not be able to use this prefix to identify the channel;

Step 42, the MBMS service server assigns an identifier to the service guide announcement channel in each area according to the agreed service guide announcement channel identification rules;

The MBMS service server assigns an identifier with a special prefix to the service guide announcement channel of each service area according to the agreed naming rules for the service guide announcement channel identifier with a special prefix.

If there are two areas, area A and area B, assuming that the bearer channel identifier is 3 bytes, the MBMS service server assigns the identifier "101" to the service announcement channel in area A, and the identifiers of other bearer channels in area A can be It is: "201", "202", "203", "204"; the identifier designated by the MBMS service server for the service announcement channel in area B is "102", and the identifiers of other bearer channels in area B can be: "205" , "206", "207", "208";

Step 43, when sending the service guide, the MBMS service server inserts the identification list of each bearer channel including the service guide announcement channel into the control information on the MCCH channel, and then broadcasts and sends it;

When the MBMS service server broadcasts and sends the corresponding MBMS information in different areas, it first allocates the bearer channel identifier according to the above rules, and then initiates a session start message; after receiving the session start message, network devices such as GGSN, SGSN and RNC allocate resources, and The MBMS bearer session is established, and the bearer channel identification list is placed in the MBMS control channel MCCH, and the bearer channel identification list includes the identification of the service guide announcement channel. After the session is established, the MBMS service server sends the service content according to the established session, and the MBMS service server specifies the service guide information to be sent and the corresponding multicast IP address and port number of the service guide (the MBMS service server can have a built-in service guide announcement channel The corresponding multicast IP address and port number, the corresponding multicast address and port number of the service guide announcement channel in different regions can be the same), after the service guide information sent in a certain area forms a data stream, the service guide announces the channel Send on broadcast.

Correspondingly, the embodiment of the present invention proposes a method for notifying bearer channel identifiers, that is, the network side assigns an identifier with a preset prefix to the service guide announcement channel, and assigns an identifier that does not have a preset prefix to other bearer channels except the service guide announcement channel. The identification of the preset prefix; and notifying the terminal side of the identification allocated for each bearer channel including the service guide announcement channel.

Preferably, the network side broadcasts the identification of each bearer channel to the terminal side on the MCCH channel.

FIG. 5 is a schematic diagram of the specific flow of the terminal side in the method for accessing the service guide announcement channel proposed in Embodiment 1 of the present invention. The flow is described as follows:

Step 51, the terminal user equipment (UE, User Equipment) reads the MCCH channel;

Step 52, the UE reads the list of bearer channel identifiers from the MCCH channel, for example: the identifier list read by the UE in area A can be: channel one "101"; channel two "201"; channel three "202" , channel four "203", channel five "204";

In step 53, the UE screens out the identifier with the agreed prefix "1" from the read identifier list, that is, channel one "101"; if there is no identifier with the agreed prefix "1" in the identifier list read by the UE mark, then go to step 56 to continue execution, otherwise continue to execute step 54;

Step 54, the UE accesses the service guide announcement channel (namely, channel 1) based on the screened out identifier "101";

When the terminal enters a certain area, in order to obtain MBMS services, it needs to read the list of all bearer channel identifiers from the MCCH channel, and determine the service guide announcement channel according to the pre-agreed service guide announcement channel identification rules.

Step 55, after the UE accesses the service guide announcement channel, obtain the service guide data stream according to the multicast IP address and port number of the service guide data stream, and read the service guide information; if the UE fails to read the service guide information, continue to execute Step 56, otherwise the process ends.

In step 56, the UE connects to the GPRS network and requests a service guide in a point-to-point manner.
