Description

Resource processing indicating method and device

Technical Field

The present invention relates to wireless mobile communication technologies, and in particular, to a method and an apparatus for indicating resource processing.

Background

The worldwide Interoperability for microwave access (WiMAX) has entered the scale test and even the commercial stage in countries such as europe, america, japan and korea due to its features of large coverage, high transmission rate, high spectrum efficiency, fast network construction speed, low construction cost, etc. WiMAX is based on the IEEE802.16 family of standards. Here, IEEE802.16-2004 (also referred to as IEEE802.16d) and IEEE802.16-2005 (also referred to as IEEE802.16e) in the IEEE802.16 series of standards are two of the most successful standards at present, and particularly, the release of IEEE802.16e is a milestone in the field of broadband mobile communication. Wherein, the IEEE802.16d supports fixed and nomadic line-of-sight (LOS) and non-line-of-sight (NLOS) transmission, namely, under the line-of-sight environment, the IEEE802.16d can work in a frequency band of 10 GHz-66 GHz; under the non-line-of-sight environment, the device can work in a frequency band less than 11 GHz. And IEEE802.16e supports the switching and roaming functions, can be applied to the vehicle speed mobile environment, and mainly works in the frequency band less than 6 GHz.

With the development of future Mobile streaming media services, the flow of multicast Service on a Mobile terminal (MS) is likely to be significantly higher than that of unicast Service to meet the demand of streaming media services in the future market, based on which, the IEEE802.16 series standard provides Multicast Broadcast Service (MBS), which may also be referred to as enhanced multicast broadcast (E-MBS) Service, similar to the Multimedia Broadcast and Multicast (MBMS) Service established by 3GPP and the broadcast and multicast (BCMCS) Service established by 3GPP2, and also provides support for multimedia broadcast and multicast functions.

IEEE802.16e defines MBS access modes: single Base Station (BS) access and multi-BS access. The single BS access is implemented by multicast broadcast Connection in a BS, that is, a radio Connection Identifier (CID) carrying MBS service and Security Association (SA) parameters corresponding to the Connection are the same for all MSs in the BS. Each participating MS receives and processes data corresponding to the CID through the MAC layer. In the multi-BS access mode, a plurality of BSs form an MBS Zone (MBS _ Zone or E-MBS _ Zone), and each MBS _ Zone has a unique Zone identifier (MBS _ Zone _ ID). Each BS in the same MBS _ Zone synchronously transmits multicast broadcast data, and transmits the content of a certain service stream by using the same multicast site identification (MSTID) and stream identification (FID), thereby forming the macro diversity effect on the participating MS. The MS acquires MBS _ Zone information from the broadcast information (E-MBS configuration indicators) of the BS. It should be noted that one base station may belong to multiple MBS _ zones simultaneously. In the multi-BS access mode, a macro diversity mode may be used to improve the reception performance. The method requires that the BS of the same MBS _ Zone synchronously sends the same data by adopting the same frequency, symbol, subchannel and modulation mode at the same time, so that the MS can simultaneously receive the MBS service from a plurality of BSs, and the receiving reliability and the receiving quality are further ensured.

Based on this, if a receiving end wants to subscribe to and watch a certain E-MBS service (also called MBS service), the following procedures are executed:

step 1, a receiving end sends an AAI _ DSA-REQ message to a base station, wherein the AAI _ DSA-REQ message carries the information of the E-MBS service requiring subscription.

And step 2, the base station sends an AAI _ DSA _ RSP message to the receiving end to confirm that the receiving end can subscribe the E-MBS service, and simultaneously, the base station provides a carrier identifier and an E-MBS region identifier of the E-MBS service.

And step 3, the receiving end receives the AAI _ EMBS _ CFG message periodically broadcasted by the base station (here, the receiving operation can also be executed before the step 2), decodes the message, and obtains the information of the E-MBS Mapping (MAP) of the area where the E-MBS service to be subscribed is located, the size, the modulation coding mode, the scheduling interval (MSI) and the like from the AAI _ EMBS _ CFG message through the known E-MBS area identifier.

And 4, the receiving end receives the E-MBS MAP information from the obtained E-MBS MAP position and decodes the E-MBS MAP information.

And step 5, the receiving end matches the subscribed E-MBS service identifier in the E-MBS MAP information. If the matching is successful, the position, the size, the modulation coding mode and the like of the subscribed E-MBS service are found.

And step 6, the receiving end judges whether the AAI _ E-MBS-CFG Change indication is 1 in the E-MBS MAP information, if so, the AAI _ EMBS _ CFG message changes, and the next AAI _ EMBS _ CFG message needs to be received, and the receiving end executes the step 3 at the appointed time because the AAI _ EMBS _ CFG message is sent according to the appointed time.

Step 7, it should be noted that, when the receiving end matches the subscribed E-MBS service identifier in step 5, if the matching is successful, the step 8 is also required. If the matching is not successful, the receiving end may also receive the next E-MBS MAP message since the E-MBS MAP message is sent periodically, i.e. go to step 4 above.

And 8, the receiving end receives and decodes the E-MBS service at the position where the subscribed E-MBS service is found. Since the E-MBS MAP message is sent periodically, the receiving end may receive the next E-MBS MAP message later, i.e. go to step 4 above.

The order of step 5 and step 6 described above may be reversed.

In the prior art, a receiving end subscribing the E-MBS service cannot predict that the E-MBS service identifier of the subscribed E-MBS service is successfully matched with the E-MBS service identifier contained in the E-MBS MAP information, so that the receiving end has to receive each E-MBS MAP information and match the E-MBS service identifier of the subscribed E-MBS service with each E-MBS service identifier in each E-MBS MAP information to determine where to receive the E-MBS service subscribed by the receiving end, which obviously causes the problems of large calculation amount, power consumption and the like. Also, in future E-MBS services, the above problem is amplified in Discontinuous Transmission (DTX) techniques, because: due to the non-continuous transmission, this will result in some, even several continuous E-MBS MAP messages not containing the E-MBS service identifier of the E-MBS service subscribed by the receiving end, so, according to the above-mentioned flow, during the transmission of E-MBS MAP information of E-MBS service identifiers which do not contain subscribed E-MBS service, the receiving end receives and matches each E-MBS service identifier in each E-MBS MAP information, finds that there is no E-MBS service which needs to be received by itself after all matching is completed, waiting for the next E-MBS smap message to be received, such an operation of matching the reception of all E-MBS service identifiers in each E-MBS MAP message would require a large amount of computation and power consumption of the receiving end, and, the consumption increases as the number of E-MBS services in the E-MBS MAP information increases.

Disclosure of Invention

An indication method of resource processing comprises the following steps:

a, a sending end sends information for indicating the resource allocation of enhanced multicast broadcast E-MBS service, wherein the information comprises a resource processing instruction related to an E-MBS service indicator needing to be processed or a resource processing instruction for indicating that the information is not processed;

B. after receiving the information, the receiving end judges whether the information contains a resource processing instruction which indicates that the information is not processed, if so, the receiving end does not process the received information; otherwise, when the information contains the resource processing indication related to the E-MBS service indicator needing to be processed, processing the currently received information according to the resource processing indication.

A method for indicating resource handling, the method comprising the steps of:

a, a sending end sends information for indicating E-MBS service resource allocation, wherein the information comprises a resource processing indication related to an E-MBS service indicator needing to be processed; or a resource handling indication indicating that the next information is not to be handled;

and B, after receiving the information, the receiving end carries out corresponding recording according to the condition of matching the E-MBS service in the received information and the resource processing instruction contained in the information, and processes the corresponding next information according to the corresponding recording.

A receiving end, after receiving the information, the receiving end judges whether the information contains a resource processing instruction for indicating not to process the information, if yes, the receiving end does not process the received information; otherwise, when the information contains a resource processing instruction related to the E-MBS service indicator needing to be processed, processing the currently received information according to the resource processing instruction; or,

after receiving the information, according to the matching condition of E-MBS service in the received information and the resource processing instruction contained in the information, making corresponding record, and processing the corresponding next information according to the corresponding record.

A sending end, said sending end sending information for indicating resource allocation of enhanced multicast broadcast E-MBS service, wherein said information includes resource processing indication related to E-MBS service indicator needing to be processed or resource processing indication indicating not to process said information; or,

sending information for indicating E-MBS service resource allocation, wherein the information comprises a resource processing indication related to an E-MBS service indicator needing to be processed; or include a resource handling indication that the next information is not to be handled.

According to the technical scheme, when the sending end sends the information for indicating the E-MBS service resource allocation based on the E-MBS service subscribed by the receiving end, the sending end judges whether the current information to be sent has the E-MBS service indicator which is not indicated in the last sent information, if so, the resource processing indication related to the E-MBS service indicator which is not indicated is added in the current information to be sent and sent to the receiving end, and if not, the resource processing indication which shows that the information to be sent is added in the current information to be sent and sent to the receiving end or the resource processing indication which shows that the current information to be sent is not processed is sent to the receiving end independently. Note that the above-described resource handling indication may also be added to the information transmitted last and transmitted to the receiving side. That is, in the present invention, the receiving end processes the information depending on the resource processing instruction in the received information, rather than blindly processing the E-MBSMAP information as in the prior art, which obviously reduces the consumption of the receiving end and reduces the computational complexity of the receiving end.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As described in the background art, the E-MBS MAP information is used to indicate the E-MBS service resource allocation information, specifically including the E-MBS service identifier and the service resource allocation information, and the receiving end finally obtains the subscribed E-MBS service resource allocation information according to the E-MBS service identifier and the service resource allocation information in the E-MBS MAP information. In order to avoid the energy consumption of a receiving end for acquiring the resource allocation information of the subscribed E-MBS service in the prior art, the invention provides an indication method for resource processing. It should be noted that the method is not limited to the E-MBS MAP information, but is also applied to other information having a function similar to the E-MBS MAP information, where the E-MBS MAP information is taken as an example for convenience of understanding the technical solution provided by the present application, and a person skilled in the art can fully apply the method by making corresponding modifications according to actual situations.

Referring to fig. 1, fig. 1 is a basic flow chart provided by an embodiment of the present invention. As shown in fig. 1, the process may include the following steps:

step 101, a sending end sends E-MBS MAP information for indicating E-MBS service resource allocation, wherein the E-MBS MAP information comprises a resource processing indication related to an E-MBS service indicator needing to be processed or a resource processing indication indicating that the E-MBS MAP information is not processed.

Step 102, after receiving the E-MBS MAP information, the receiving end judges whether the E-MBS MAP information contains a resource processing instruction which indicates that the E-MBS MAP information is not processed, if so, the receiving end does not process the E-MBS MAP information; otherwise, when the E-MBS MAP information contains a resource processing instruction related to the E-MBS service indicator needing to be processed, processing the currently received E-MBS MAP information according to the resource processing instruction.

Thus, in the embodiment of the present invention, the receiving end may process the E-MBS MAP information according to the resource processing indication in the E-MBS MAP information sent by the sending end, instead of blindly processing the E-MBS MAP information as in the prior art, where the processing of the E-MBS MAP information by the receiving end according to the resource processing indication in the received E-MBS MAP information may specifically include: the received E-MBS MAP information is not processed, a part of E-MBS service indicators in the received E-MBS MAP information is processed, all E-MBS service indicators in the received E-MBS MAP information are processed, and the like, which will be described in detail below. Therefore, the invention can ensure that the receiving end processes the E-MBS MAP information in a targeted way, and can not cause the problems of calculation, power consumption and the like caused by blindly processing all E-MBS MAP information in the prior art.

It should be noted that, when the step 101 is implemented specifically, the method may include:

a11, when the sending end sends the E-MBS MAP information used for indicating the E-MBS service resource allocation based on the E-MBS service subscribed by the receiving end, judging whether the E-MBS MAP information to be sent currently has the E-MBS service indicator which is not indicated in the E-MBS MAP information sent last time, if so, executing the step A12, otherwise, executing the step A13;

a12, determining the resource processing indication related to the E-MBS service indicator needing to be processed according to the number of the E-MBS service indicator not being indicated and the bit number allowed to be occupied by the resource processing indication, adding the determined resource processing indication related to the E-MBS service indicator needing to be processed in the current E-MBS MAP information to be sent and sending the E-MBS MAP information to a receiving end or sending the determined resource processing indication related to the E-MBS service indicator needing to be processed to the receiving end separately;

a13, adding a resource processing instruction which represents no processing information in the current E-MBSMAP information to be sent, and sending the E-MBSMAP information to a receiving end; or an indication indicating that the information is not to be processed may be sent to the receiving end separately.

When the operation of adding the resource processing indication related to the E-MBS service indicator to be processed to the E-MBS MAP information to be currently sent in step a12 is specifically implemented, the existing E-MBS MAP information may be expanded. Referring to fig. 2a, fig. 2a is a diagram illustrating an existing E-MBS MAP message. In fig. 2a, the E-MBS MAP information includes an E-MBS service identifier list (E-MBS _ DATA _ IE), where the E-MBS _ DATA _ IE includes 8 bits For indicating the number of E-MBS services, and a plurality of E-MBS service identifiers and corresponding service resource allocation indication information thereof, and here, in order to facilitate the receiving end to process the E-MBS service identifiers, the plurality of E-MBS service identifiers and corresponding service resource allocation indication information thereof may form a 'For' cycle, where each E-MBS service identifier in the 'For' cycle is formed by an MSTID and an FID, and occupies 16 bits. Based on this, step a12 may add a resource handling indication (denoted as mode 1) related to the E-MBS service indicator to be handled before the E-MBS _ DATA _ IE of the E-MBS MAP information to be currently sent, or outside the 'For' loop formed by multiple E-MBS service identifiers and corresponding service resource allocation information, where the resource handling indication occupies M bits, as shown in fig. 2 b. Preferably, as another embodiment of the present invention, step 102 may also add a resource processing indication (denoted as manner 2) related to the E-MBS service indicator to be processed within the above-mentioned 'For' cycle included in the E-MBS _ DATA _ IE in the E-MBS MAP information to be currently sent, and in a specific implementation, a bit may be added after each non-indicated E-MBS service indicator to indicate that the E-MBS service indicator is information that is not indicated by the previous E-MBS MAP information, as shown in fig. 2 c. The above are only examples of the present invention and are not intended to limit the above two embodiments.

The method provided by the embodiment of the invention is described in detail in the following manner 1, taking E-MBS MAP information as an example. The working principle and application of the mode 2 will be fully understood by those skilled in the art from the detailed description of the mode 1.

Referring to fig. 3a, fig. 3a is a flowchart of sending E-MBS MAP information by a sending end according to an embodiment of the present invention. In this embodiment, a resource processing indication field (hereinafter referred to as an indicator) may be added to the E-MBS MAP information, and the indicator may occupy M bits, which is slightly different from the method 1, as another embodiment of the present invention, instead of adding the indicator to the E-MBS MAP information, an indicator may be added to other messages independent of the E-MBS MAP information, even an individual transmission indicator, for example, an individual transmission indicator using a pseudo random code, etc., but it is required to ensure that a time interval for transmitting the indicator is equal to a transmission interval of the E-MBS MAP information, that is, the MSI, to ensure that the receiving end can process the received E-MBS MAP information according to the indication of the indicator. Taking the example of adding the indicator in the E-MBS MAP information, as shown in fig. 3a, the process mainly includes the following steps:

step 301a, when a sending end sends E-MBS MAP information, judging whether an E-MBS service indicator which is not indicated in the previous E-MBS MAP information exists in the E-MBS MAP information to be sent currently, if so, executing step 302 a; otherwise, step 305a is performed.

That is, when the sending end sends the E-MBS smap information based on the request of the receiving end for subscribing the E-MBS service, the sending end first compares the E-MBS MAP information to be sent currently with the E-MBS service indicator in the last E-MBS smap information sent, and if the former has the E-MBS service indicator that the latter does not have, then step 302a is executed; otherwise, step 305a is performed.

Step 302a, determining the number x of E-MBS service indicators which are not indicated in the last E-MBSMAP information and exist in the E-MBS MAP information to be sent currently.

Here, the number of the E-MBS service indicators that are not indicated in step 302a is determined in advance by the system according to its own requirements and practical situations, and step 302a does not perform relevant scheduling, but only obtains the number x.

Step 303a, determining the number of the E-MBS service indicators to be processed according to the number x of the E-MBS service indicators which are not indicated and the bit number allowed to be occupied by the indicators.

Here, the number of the E-MBS service indicators to be processed in step 303a is an implementation manner of the above-mentioned resource processing indication related to the E-MBS service indicators to be processed, and preferably, the resource processing indication related to the E-MBS service indicators to be processed may also include other manners, and those skilled in the art may make corresponding modifications according to actual situations. Wherein, the operation of step 303a is:

the transmitting end may indicate Pi at most if based on the number of bits the indicator is allowed to occupy_maxAn E-MBS service indicator, then,

pi when based on the actual conditions or conventions of the system_maxPi is always greater than or equal to the number x of the E-MBS service indicators which are not indicated_maxThe non-indicated E-MBS service indicator can be indicated without being transferred, and based on the fact, the number of the E-MBS service indicators needing to be processed can be determined to be more than or equal to the non-indicated E-MNumber of BS service indicators, and is less than or equal to Pi_maxPlacing the x E-MBS service indicators which are not indicated at the appointed position in the E-MBS MAP information to be sent currently;

when Pi is determined according to the actual conditions or conventions of the system_maxPi is less than the number x of the E-MBS service indicator which is not indicated_maxEscape to the number x of E-MBS service indicators not indicated (Here, Pi_maxSee later embodiments for details of being escaped) based on which if Pi_maxWhen the number of the E-MBS service indicators needing to be processed is less than x, the number of the E-MBS service indicators needing to be processed is determined to be the number x of the E-MBS service indicators which are not indicated or the total number of all E-MBS service indicators in the current information to be sent, at this time, the x E-MBS service indicators which are not indicated can be placed at the specified position in the current E-MBSMAP information to be sent, wherein Pi is_maxWhen the number x of the E-MBS service indicators which are not indicated is less than the number x of the E-MBS service indicators which are not indicated, the x E-MBS service indicators which are not indicated are also placed at the appointed position in the E-MBSMAP information to be sent currently, so that two types of receiving ends can conveniently eliminate the E-MBS service indicators which do not need to be matched, and the consumption is saved. For example, when x is 6, Pi_max＝4，Pi _max22, when the total number of the E-MBS service indicators in the E-MBS smap information to be currently sent is 100, the sending end places the 6E-MBS service indicators that are not indicated at the appointed position agreed in the E-MBS MAP information to be currently sent, and assumes that the appointed position is the foremost end of all information (i.e. the foremost position after 8 bits for indicating the number of E-MBS services in the E-MBS MAP information) so that, for a certain receiving end, when it receives the E-MBS MAP information, if the E-MBS service indicator subscribed to it is not in the last E-MAP information, it sequentially matches each E-MBS service indicator starting from the foremost end of all information in the E-MAP information currently received, for example, when it matches the 6 th E-MBS service indicator at the appointed position, the E-MBS service indicator subscribed by the receiver can be found, so that the receiver can quickly find the needed E-MBS service indicator, and the consumption is saved. At the same time, for another classThe receiving end, if the E-MBS service indicator that it needs to receive exists in the last E-MBS MAP information, actually it does not need to match the first x E-MBS service indicators, then according to the appointed position convention, it can match the E-MBS service indicator outside the appointed position, such as directly from Pi_max2+1, namely starting to match backwards at the 3 rd E-MBS service indicator, or starting to match forwards from the rearmost end until the 3 rd E-MBS service indicator, without matching the first 2E-MBS service indicators, which is convenient for the receiving end to eliminate the E-MBS service indicators which do not need to be matched, thereby saving consumption. Wherein the transmitting end may also indicate Pi based on the number of bits the indicator is allowed to occupy_max2E-MBS service indicator, Pi_max2The number of the E-MBS service indicators which can be indicated by the sending end is only less than Pi_maxThe numerical value of (c).

Of course, as another embodiment of the present invention, when Pi_maxAnd when the number x of the E-MBS service indicators is less than the number x of the E-MBS service indicators which are not indicated, the appointed position does not need to be appointed.

It should be noted that the specified position may be the foremost position of all information, the rearmost position of all information (i.e., the rearmost position after 8 bits that do not contain the E-MBS service identifier list in the E-MBS MAP information) or other positions that can be clearly known by the receiving end.

Step 304a, adding the number determined in step 303a into the indicator in the E-MBS MAP message to be sent currently, and sending to the receiving end.

Step 305a, adding the parameter value which represents no processing in the indicator in the E-MBS MAP information to be sent currently, and sending to the receiving end.

Preferably, as another embodiment of the present invention, when the determination result in step 301a is negative, only the parameter value indicating that the processing is not performed may be sent to the receiving end separately without occupying the resource of the E-MBS MAP information, and the specific situation is specifically analyzed, which is not limited herein. In the following, the example of adding a parameter value indicating no processing to the E-MBS MAP information is given.

So far, the operation of the sending end sending the E-MBS MAP information to the receiving end is realized through the above operation, which can be embodied by the schematic diagram shown in fig. 4.

The following describes the operation of processing the E-MBS MAP information by the receiving end in conjunction with a specific embodiment.

Referring to fig. 3b, fig. 3b is a flowchart of a processing of the receiving end according to an embodiment of the present invention. In this embodiment, when the receiving end receives the E-MBS MAP information in fig. 4 embodying the procedure in fig. 3a, as shown in fig. 3b, the procedure may include the following steps:

step 301b, if the receiving end does not match the E-MBS service subscribed by the receiving end in the last E-MBS MAP information, step 302b is executed; if the E-MBS service subscribed by itself has been matched in the last E-MBS MAP information, then step 304b is executed.

Step 302b, the receiving end judges whether the indicator in the E-MBS MAP information received currently contains a parameter value which represents that the E-MBS MAP information is not processed, if so, the E-MBS MAP information is not processed; otherwise, step 303b is performed.

Step 303b, the receiving end determines the number of indicators contained in the E-MBS MAP information, and performs corresponding processing according to the determined number.

Here, the performing the corresponding processing according to the determined number in step 303b may specifically include:

if the determined number is the total number of all E-MBS service indicators in the E-MBS MAP information, matching the E-MBS service indicator of the subscribed E-MBS service with the E-MBS service indicator in the currently received E-MBS MAP information until the matching is successful or all the E-MBS service indicators are matched to obtain the position information of the subscribed E-MBS service, wherein the matching range is all the E-MBS service indicators in the currently received E-MBS SMAP information; in addition, if the appointed position is appointed in the currently received E-MBS MAP information, the E-MBS service indicator should be matched according to the sequence of firstly appointing the position and then forwards or backwards along the appointed position; if the determined number is not the total number of all E-MBS service indicators in the E-MBS MAP information, only the E-MBS service indicator of the subscribed E-MBS service needs to be matched with the E-MBS service indicator at the specified position in the currently received E-MBS MAP information so as to obtain the position information of the subscribed E-MBS service.

And step 304b, the receiving end matches the E-MBS service indicator which is positioned outside the appointed position in the currently received E-MBS MAP information. That is, according to the indicator in the E-MBS MAP message and the convention of the designated location, the receiving end can know which locations definitely place the E-MBS service indicator that is not indicated in the previous E-MBS smap message, and further can determine to match the E-MBS service indicator outside the location.

Since the E-MBS service indicator existing at the designated location of the currently received E-MBS MAP information is not indicated by the last E-MBS MAP information, it is obvious that the receiving end needs to match the E-MBS service indicator located outside the designated location.

It should be noted that, as a specific example, if a receiving end subscribes to at least two E-MBS services, one of the E-MBS services has been successfully matched in the previous E-MBS MAP information, in order to avoid missed detection of the E-MBS service, the receiving end needs to process all E-MBS service indicators in the E-MBS MAP information to be currently received.

In order to make the embodiment of the present invention clearer, the flow shown in fig. 3a and 3b will be described in combination with several embodiments.

Taking the example of adding the indicator in the E-MBS MAP information, wherein the number of bits M occupied by the indicator added in the E-MBS MAP information is a positive integer, M may have various forms in specific implementation, for example, M may be 1, 2 or other values, and the following description will take M as 2 and M as 1 as examples.

Taking M as 2 as an example, the indicator may take four values of "00", "01", "10" and "11", and if M is 2, the indicator may indicate at most P3E-MBS service indicators, and the corresponding relationship between the value of the indicator and the number of indicated E-MBS service indicators that need to be processed by the receiving end may be as follows: when the indicator is '00', corresponding to not processing any E-MBS service indicator in the E-MBS MAP information, namely '00' is a parameter value which represents not processing; when the indicator is '01', corresponding to P1E-MBS service indicators in the E-MBS MAP information; when the indicator is '10', corresponding to P2E-MBS service indicators in the E-MBS MAP information; when the indicator is '11', it corresponds to processing P3E-MBS service indicators in the E-MBS MAP information.

Preferably, as an extension of the present invention, it is not assumed that P1 < P2 < P3, and P1, P2 and P3 may be discontinuous, and when the number of the non-indicated E-MBS service indicators determined in step 302 is x and P1 < x < ═ P2, it may be determined that the number of the E-MBS service indicators required to be processed is P2, and P2 corresponds to "10", and the value of the indicator is set to "10". That is, when the number of the E-MBS service indicators processed by the indicator is not exactly equal to the number of the non-indicated E-MBS service indicators determined in step 302a, the indicator may indicate that the number of the E-MBS service indicators processed by the indicator is a larger value, so as to avoid missed detection, that is, the number of times of matching is insufficient, but when the receiving end receives the corresponding E-MBS MAP information, if the E-MBS service indicator that it needs to receive exists in the previous E-MBS MAP information, in order to avoid missed detection, in step 304b, the E-MBS service indicator needs to be matched from a smaller value close to the larger value. For example, if the number of the non-indicated E-MBS service indicators determined in step 302a is x, and P1 < x ≦ P2, the indicator may be "10", and when the receiving end receives the E-MBS MAP information, if the non-indicated E-MBS service indicator is placed at the front end, when the E-MBS service subscribed by the receiving end is successfully matched in the last E-MBS MAP information, the receiving end does not match the E-MBS service indicator backward from the value corresponding to "10", i.e., P2, but starts to match the E-MBS service indicator backward from the last value of P2, i.e., P1, which is the value corresponding to "01", which obviously can avoid missing detection.

Here, P1, P2, and P3 (collectively, Pi, i is a positive integer) are positive integers, Pi may be set to i at the simplest, and Pi may be set to f (i), where f (i) is a mathematical function, and f (i) and i have a one-to-one correspondence, which may be a linear relationship or a nonlinear relationship: for example, f (i) ═ 2 × i, or f (i) ═ 2 × i-1, or f (i) ═ 2ⁱ-1, or f (i) 2ⁱAnd so on. Note that, depending on the specific application, the above Pi value may be ambiguous, for example, if the receiving end is further required to process 4, 5 or more E-MBS service indicators in the E-MBS MAP information, and the indicator can indicate at most 3E-MBS service indicators accurately, it is required for this case that the P3 in the indicator is ambiguous to process at least P3E-MBS service indicators in the E-MBS MAP information, or even ambiguous to process all E-MBS service indicators in the E-MBS MAP information. It should be noted that, in this embodiment, as long as the value of the indicator corresponds to the number of the E-MBS service indicators in the E-MBS MAP information that needs to be processed by the receiving end, it is not necessary to require that the indicator takes the minimum value of "00" to only definitely indicate that the E-MBS MAP information is not processed, and it is also not necessary to require that the indicator takes the maximum value of "11" to only definitely indicate that P3 or at least P3 or all E-MBS service indicators in the E-MBS MAP information are processed, and the specific setting may be limited according to the actual situation.

Taking Pi as 2 × i as an example, in step 302b, when the receiving end receives the E-MBS MAP information, if the indicator in the E-MBS MAP information takes the value of "00", it is not necessary to match the E-MBS service identifier in the E-MBS MAP information, and it is only required to directly wait for receiving the next E-MBS MAP information; if the information indicator is set to '01', which means that P1 is P1, that is, 1E-MBS service identifier, only one E-MBS service identifier at the head of the service identifier list needs to be matched to check whether it is a required service, and if so, further obtain resource allocation information corresponding to the required service; if not, directly waiting for receiving the next E-MBS MAP information; if the information indicator is set to '10', indicating that P2 is 2E-MBS service identifiers, it only needs to match the top 2E-MBS service identifiers in the service identifier list, check whether there is a service required by it, and if so, further obtain the corresponding resource allocation information; if not, directly waiting for receiving the next E-MBS MAP information. If the information indicator is set to '11', which means that P3 is P3, that is, 3E-MBS service identifiers, it is only necessary to match the top 3E-MBS service identifiers in the service identifier list, check whether there is a service required by the service identifier list, and if so, further obtain corresponding resource allocation information; if not, directly waiting for receiving the next E-MBS MAP information. If the information indicator is set to '11' and represents all E-MBS service identifiers, matching is required to be carried out in all E-MBS service identifier ranges in the whole service identifier list until the matching is successful or all E-MBS service indicators are matched, namely whether the required services exist is checked, and if the required services exist, corresponding resource allocation information is further acquired; and if all the service identifiers are found not to match the required service identifiers, waiting for receiving the next E-MBS MAP information.

The above description describes the correspondence between the information indicated by the indicator and the operation of the E-MBS MAP information processing required to be processed by the receiving end, taking M as an example 2, and the simplest case, that is, taking M as an example, is described briefly below, where when M is equal to 1, the value of the indicator may be "0" or "1", and the correspondence between the value of the indicator and the number of the indicated E-MBS service indicators required to be processed by the receiving end may be as follows: when the indicator is '0', corresponding to not processing any E-MBS service indicator in the E-MBS MAP information; when the indicator is "1", it corresponds to processing P4E-MBS service indicators in the E-MBS MAP information, or at least P4E-MBS service indicators, where P4 represents the total number of all E-MBS service indicators in the E-MBS MAP information, or a default value other than 0, such as 1, 2, or 3. For the receiving end which has matched the E-MBS service subscribed in the last E-MBS MAP information, the receiving end should match all E-MBS service indicators except the 1 st E-MBS service indicator at the appointed position in the currently received E-MBS MAP information, because it can not determine that several E-MBS service indicators at the appointed position are not appointed.

As described above, when the determination result in step 301a is negative, only the resource processing indication indicating that the E-MBS MAP information is not processed may be sent to the receiving end alone, without occupying the resource of the E-MBS MAP information. If the above applies to the above case, '00' or '0' may not correspond to not processing any one E-MBS service indicator in the E-MBS MAP information but may correspond to processing P0E-MBS service identifiers, with P0 being a positive integer.

It should be noted that, in the above example where M is 2 or 1, all the E-MBS service indicators in the E-MBS MAP information are processed, which is not necessarily the case, for example, in an application, the number of the E-MBS service indicators that are not indicated in the last E-MBS MAP information existing in the E-MBS MAP information to be currently sent in step 302a, that is, the maximum value of X, is limited, and is assumed to be X₁And the maximum value X₁The indicator not greater than the E-MBS MAP information can indicate the number of processed E-MBS service indicators, namely the maximum value Pi in the Pi_maxIn the process, obviously, all E-MBS service indicators in the E-MBSMAP information do not need to be processed, so that how to set the corresponding relation between the value of the indicator and the number of the indicated E-MBS service indicators needing to be processed by the receiving end can be seen, and the processing is completely carried out according to the requirements and the actual conditions of the system.

It should be noted that, in the embodiment of the present invention, the receiving end processes the received E-MBS MAP information according to the indication of the indicator, and the indication of the indicator depends on the comparison result of the E-MBS service indicator in the E-MBS MAP information to be sent and the last E-MBS MAP information sent when the sending end sends the E-MBS MAP information, and if the sending end sends the E-MBS MAP information for the first time after the E-MBS zone is established, there is no last E-MBS MAP information, so that, in order to save the sending end resources, the E-MBS MAP information can be processed according to the existing manner.

It should be noted that, the above is to determine the indication of the indicator according to the comparison result between the currently sent E-MBS MAP information and the last sent E-MBS MAP information, and preferably, as an extension of the embodiment of the present invention, other manners may be adopted instead, such as: the method comprises the steps that a sending end sends information for indicating E-MBS service resource allocation based on an E-MBS service subscribed by a receiving end, namely when the information to be sent is currently sent, part or all E-MBS service indicators of the next unsent information are scheduled at the same time, wherein the next unsent information can be scheduled by the sending end such as a base station, and is not limited; and then, judging whether the next message has an E-MBS service indicator which is not indicated by the current message to be sent, if so, adding a resource processing indication related to the E-MBS service indicator which needs to be processed in the current message to be sent, and sending the message to a receiving end, and if not, adding a resource processing indication which indicates that the next message is not processed in the current message to be sent, and sending the message to the receiving end. That is to say, in this embodiment, the E-MBS smap information sent by the sending end includes a resource processing indication related to an E-MBS service indicator that needs to be processed; or include a resource handling indication that the next information is not to be handled. It should be noted that, if the sending end sends the last E-MBS MAP message, it may process the message according to the existing method in order to save the sending end resources because there is no next E-MBS MAP message.

Preferably, in this alternative, adding the resource processing indication related to the E-MBS service indicator to be processed to the current information to be sent may be specifically performed in the above-mentioned adding manner, and is not limited herein. Wherein, the alternative is different from the processing of the receiving end in the above-mentioned scheme, and is described below.

In this alternative, when receiving information, the receiving end performs corresponding recording according to the condition that the E-MBS service is currently matched in the received information and the resource processing instruction included in the information, and processes the corresponding next information according to the corresponding recording, which may specifically include:

if the received information is received for the first time, matching the E-MBS service subscribed by the user in the information, if the matching is unsuccessful, and when the received information contains a resource processing instruction which indicates that the next information is not processed, recording that the next information is not processed, namely, the next information is not received, or when the next information is received, the received information is not required to be decoded; when the received information contains a resource processing instruction related to the E-MBS service indicator needing to be processed, recording the number of the E-MBS service indicator needing to be processed contained in the resource processing instruction; if the matching is successful, when the received information contains a resource processing instruction which indicates that the next information is not processed, recording the next information to be processed (because the matching is successful in the currently received E-MBS service indicator, but not the E-MBS service indicator which is not indicated in the currently received information and exists in the next information, therefore, when the next information is received, the information needs to be processed), and when the received information contains the resource processing instruction related to the E-MBS service indicator which needs to be processed, recording the number of the E-MBS service indicators which need to be processed and are contained in the resource processing instruction;

then, if the record is that the next information is not processed, the next information is not received, and the corresponding record is deleted; otherwise, when the next information is received, processing the next information according to the record corresponding to the next information; or, when the next message is received, if the record is that the next message is not processed, and the record is deleted; otherwise, the next information is processed according to the record corresponding to the next information.

Wherein, processing the next information according to the record corresponding to the next information specifically includes:

if the record is to process the information, processing the currently received information, and after the processing is finished, updating the record to a record corresponding to the resource processing instruction in the currently received information;

if the number included in the resource processing indication is recorded, for the receiving end which is not successfully matched in the previous information, if the determined number indicates the total number of all E-MBS service indicators in the currently received information, and the receiving end appoints a specified position in the currently received information, the E-MBS service indicator of the E-MBS service subscribed by the receiving end is matched with the E-MBS service indicator at the specified position; when the appointed position is not appointed, matching the E-MBS service indicator of the E-MBS service subscribed by the E-MBS service with all E-MBS service indicators in the currently received information until the matching is successful or all E-MBS service indicators are matched; and if the determined number does not represent the total number of all E-MBS service indicators in the currently received information, only matching the E-MBS service indicator of the subscribed E-MBS service with the E-MBS service indicator at the specified position in the currently received information. And for the receiving ends successfully matched in the last information, the operation is performed according to the determined number and with reference to the step 304 b. And after processing, updating the record to the record corresponding to the indicator in the currently received message according to the actual condition of the receiver.

Thereafter, when the next information arrives, if the record has been deleted, the operation is performed as when the information is first received, or the record is treated as the maximum number that the resource handling instruction can contain. If there is a record, the operation is performed in accordance with the above-described method of processing the next information.

The method provided by the embodiment of the invention is described above, and the device provided by the embodiment of the invention is described below. The device provided by the embodiment of the invention comprises a sending end and a receiving end, wherein, the information sent by the sending end, such as E-MBS MAP information, can be realized in various ways, and the following two ways are described:

the first mode is as follows: a sending end sends information for indicating the resource allocation of enhanced multicast broadcast E-MBS service, wherein the information comprises a resource processing instruction related to an E-MBS service indicator needing to be processed or a resource processing instruction for indicating that the information is not processed;

the second mode is as follows: sending information for indicating E-MBS service resource allocation, wherein the information comprises a resource processing indication related to an E-MBS service indicator needing to be processed; or include a resource handling indication that the next information is not to be handled.

The apparatus at the transmitting end is detailed below for two different ways.

Referring to fig. 5a, fig. 5a is a structural diagram of a first sending end according to an embodiment of the present invention. The sending end may specifically be a base station, and as shown in fig. 5a, the sending end includes:

In fig. 5a or fig. 5b, when the resource processing indication related to the E-MBS service indicator to be processed is added to the current information to be sent by the first sending unit 502a or the second sending unit 502b, the method may be implemented as follows, for example: adding a resource processing indication field related to an E-MBS service indicator needing to be processed before a service identifier list E-MBS _ DATA _ IE contained in the current information to be sent, or outside a 'For' cycle formed by a plurality of E-MBS service identifiers in the E-MBS _ DATA _ IE and service resource allocation information corresponding to the E-MBS service identifiers, as shown in FIG. 2b in the method; or, a resource processing indication field related to the E-MBS service indicator to be processed is added in a 'For' cycle formed by a plurality of E-MBS service identifiers and service resource allocation information corresponding to the E-MBS _ DATA _ IE in the current information to be transmitted, as shown in fig. 2c in the method.

In a specific implementation, the first sending unit 502a or the second sending unit 502b may include:

an adding subunit 5022, configured to add the number determined by the determining subunit 5021 into the resource processing indication field in the information to be currently sent.

Here, Pi can be indicated if the number of bits that the resource handling indication field is allowed to occupy is at most_maxAn E-MBS service indicator, then,

determining subunit 5021 as Pi_maxWhen greater than or equal to the total number of the E-MBS service indicators which are not indicated, if Pi_maxIf not, determining that the number of the E-MBS service indicators needing to be processed is more than or equal to the total number of the E-MBS service indicators which are not indicated and is less than or equal to Pi_max(ii) a When Pi_maxIf Pi is smaller than the total number of the E-MBS service indicators which are not indicated_maxIf the E-MBS service indicator can be transferred, determining the number of the E-MBS service indicators needing to be processed as the total number of the E-MBS service indicators which are not indicated or the total number of all the E-MBS service indicators in the current information to be sent;

based on this, the adding subunit 5022 may also place the corresponding non-indicated E-MBS service indicator at a specified position in the current information to be sent according to the number of the E-MBS service indicators determined by the determining subunit 5021 to be processed; or,

at Pi_maxMore than or equal to the total number of the E-MBS service indicators which are not indicated, the E-MBS service indicators corresponding to the number of the E-MBS service indicators which are not indicated are placed at the appointed position in the current information to be sent according to the number of the E-MBS service indicators which are determined by the determining subunit 5021 and need to be processed; at Pi_maxAnd when the total number of the E-MBS service indicators which are not indicated is less than the total number of the E-MBS service indicators which are not indicated, not placing the E-MBS service indicators corresponding to the determined number of the E-MBS service indicators which need to be processed at the specified position.

Correspondingly, the invention also provides another indicating device structure for resource processing, which is specifically shown in fig. 6. Referring to fig. 6, fig. 6 is a structural diagram of a receiving end according to an embodiment of the present invention. The receiving end may be an MS, as shown in fig. 6, after receiving the information, the receiving end determines whether the information includes a resource processing instruction indicating that the information is not to be processed, and if so, does not process the received information; otherwise, when the information contains a resource processing instruction related to the E-MBS service indicator needing to be processed, processing the currently received information according to the resource processing instruction; or,

In specific implementation, the receiving end may include:

a receiving unit 601, configured to receive information that is sent by a sending end based on a self-subscribed E-MBS service and used for indicating resource allocation of the E-MBS service; here, the information may be, for example, E-MBS MAP information or other information with similar functions, and the embodiment is not limited in particular.

A processing unit 602, configured to process the information according to the resource processing instruction in the information received by the receiving unit 601. As shown in fig. 6, the processing unit 602 may include:

a first determining subunit 6021, configured to determine, when the E-MBS service subscribed by the apparatus is not matched in the previous information, whether a resource processing instruction indicating that the information is not to be processed is included in the currently received information;

a first processing subunit 6022 for not processing the received information when the judgment result of the judgment subunit 6021 is yes; when the judgment result of the judgment subunit 6021 is negative, determining the number contained in the resource processing indication field in the currently received information, and processing the currently received information according to the determined number;

a second processing subunit 6023, configured to match the E-MBS service indicator outside the specified location in the currently received information when the E-MBS service subscribed by the apparatus has been matched in the previous information.

Here, the processing of the currently received information by the first processing sub-unit 6022 based on the determined number includes:

if the determined number is the total number of all the E-MBS service indicators in the currently received information, matching the E-MBS service indicator of the E-MBS service subscribed by the E-MBS service provider with the E-MBS service indicator at the specified position when the specified position is agreed in the currently received information, for example, matching the E-MBS service indicator in the sequence of first specifying the position and then forward or backward along the specified position, which may specifically refer to the description of the relevant reception in step 303 b; when the appointed position is not appointed in the current received information, matching the E-MBS service indicator of the E-MBS service subscribed by the E-MBS service with all E-MBS service indicators in the current received information, wherein the matching range is all E-MBS service indicators until the matching is successful or all E-MBS service indicators are matched;

and if the determined number is not the total number of all E-MBS service indicators in the currently received information, only matching the E-MBS service indicator of the subscribed E-MBS service with the E-MBS service indicator at the specified position in the currently received information.

Preferably, as shown in fig. 6, the processing unit 602 may also be replaced with:

a second determination subunit 6024 for determining, upon receipt of the information, if the information is first received,

matching the E-MBS service subscribed by the user in the information; for operating as when the information is first received if the record has been deleted when the next information arrives for the next information in the processing subunit 6026 (6024 n).

A recording subunit 6025, configured to record not to process the next information when the resource processing indication in the received information indicates not to process the next information when the matching is unsuccessful, and record the number included in the resource processing indication when the resource processing indication in the received information is related to the non-indicated E-MBS service indicator; when the matching is successful, recording and processing the next information when the resource processing instruction in the received information indicates that the next information is not processed; when the resource processing indication in the received information is related to the E-MBS service indicator which is not indicated, recording the number contained in the resource processing indication;

a processing sub-unit 6026 for directly controlling the receiving unit 601 so as not to receive the next information if it is recorded as not to process the next information when the next information arrives; or is configured to, when receiving the next information, mark the next information as currently received information, and process the currently received information according to the record corresponding to the currently received information in the record subunit 6025.

Wherein, when the record is not to process the currently received information, the processing subunit 6026 does not process the currently received information and deletes the record; when the record is used for processing the currently received information, and after the processing is finished, updating the record into a record corresponding to an indicator in the currently received information according to the actual condition of a receiver; when the record is the number contained in the resource processing indication, for the receiving end which is not successfully matched in the previous information, if the determined number represents the total number of all E-MBS service indicators in the currently received information, matching the E-MBS service indicator of the E-MBS service subscribed by the receiving end with the E-MBS service indicator at the specified position when the specified position is appointed in the currently received information; when the appointed position is not appointed, matching the E-MBS service indicator of the E-MBS service subscribed by the E-MBS service with all E-MBS service indicators in the currently received information until the matching is successful or all E-MBS service indicators are matched; and if the determined number does not represent the total number of all E-MBS service indicators in the currently received information, only matching the E-MBS service indicator of the subscribed E-MBS service with the E-MBS service indicator at the specified position in the currently received information. And for the receiving ends successfully matched in the last information, the operation is performed according to the determined number and with reference to the step 304 b. And after processing, updating the record to the record corresponding to the indicator in the currently received message according to the actual condition of the receiver.

When the next information arrives, if the record is deleted, the record is regarded as the maximum number that the resource processing instruction can contain (6026 n). If there is a record, the operation is performed in accordance with the above-described method of processing the next information. Of these, 6024n and 6026n only select one of them to operate.

Thus, the description of the apparatus provided in the embodiment of the present invention is completed.

According to the technical scheme, when a sending end subscribes an E-MBS service to send information for indicating E-MBS service resource allocation, such as E-MBS MAP information, based on a receiving end, the sending end judges whether an E-MBS service indicator which is not indicated in the previous information exists in the current information to be sent, if so, a resource processing indication related to the E-MBS service indicator which is not indicated is added in the current information to be sent, and the resource processing indication is sent to the receiving end, so that the receiving end processes the indication processing information according to the resource processing indication in the P information sent by the sending end. The resource handling indication may also be added to the last transmitted information to be transmitted to the receiving end. According to the above description, the receiving end may specifically process the information according to the resource processing instruction in the received information, including: not processing the received information, processing a part of E-MBS service indicators in the received information, processing all service indicators in the received information, etc. Even still include: the information is not received, i.e. not decoded. That is, in the present invention, the receiving end processes the indication processing information depending on the resource in the received information, rather than blindly processing the E-MBS MAP information as in the prior art, which obviously reduces the consumption of the receiving end, and reduces the computational complexity of the receiving end, and improves the working efficiency of the system.

Furthermore, in the embodiment of the invention, the service identifier which is not indicated by the previous information is indicated at the specified position of the information such as the E-MBS MAP information, so that the receiving end can easily eliminate the E-MBS service indicator which does not need to be matched, thereby saving the consumption;

furthermore, the receiving end processes the indication processing information depending on the resources in the information, and does not process the information blindly as in the prior art, which can better support discontinuous transmission and better support the receiving end in a dormant state; and the advantages are more prominent when the number of services in the multicast broadcast service area is large.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
