    摘要: A method, template, protocol, apparatus, system, and computer software for implementing a binary protocol for session initiation in a wireless communications system. The method for creating, modifying or terminating an IP multimedia session among one or more binary session initiation protocol (B-SIP) entities includes providing a flexible template with at least one mandatory field and at least one optional field, wherein the flexible template has fixed and variable length fields, representing a message type with a template id, and maintaining session specific information in a cache. The message template for creating, modifying or terminating an IP multimedia session among one or more binary session initiation protocol (B-SIP) entities, includes at least one mandatory field and at least one optional field, at least one fixed length field and at least one variable length field, wherein each of said at least one variable length fields is preceded by a length field and each of said at least one optional fields is preceded by an identifier, wherein said at least one mandatory field precedes said at least one optional field and said at least one fixed length field precedes said at least one variable length field.

    摘要: Transmission methods for multicast messages and for signaling message responses thereto in communication systems supporting a multicast mode provide that a number of retransmissions of a multicast message may be changed based on a number of receivers of the message. Signaling messages to the multicast message may be transmitted in response to a fixed number of multicast message transmissions, and receivers that have not received the multicast message after the fixed number of transmissions may request further retransmissions up to an additional given number of times. Further, signaling messages may be transmitted at different times or staggered based on a radio condition of the receivers. For example, a first multicast message may be transmitted, and responses from groups of receivers may be listened to for a given period, after which one of a next multicast message and a portion of the first multicast message may be transmitted to the groups.

    摘要: A method, apparatus, system, and computer software for compressing and decompressing a message for transmission. The method of compressing a text message for transmission may include parsing text strings and encoding numerical values with a binary representation and analyzing values of the text strings and populating a session specific codebook with partial strings from the values. The method of compressing a message for transmission may also include parsing the message with a template and generating at least one substring to be transmitted; parsing the at least one substring with entries in a session specific codebook and generating a first part of the compressed message; populating the session specific codebook with entries for unknown field values; parsing any unmatched substrings with entries from a first static dictionary and generating a second part of the compressed message; parsing any still unmatched substrings with entries from a second static dictionary and generating a third part of the compressed message; compressing a remainder of the substrings with a compression algorithm; and combining the first part, the second part, and the third part of the compressed message to obtain a compressed message for transmission.

    摘要: In the dynamic access priority method, priority classes with different backoff delays are used to prioritize random access over shared channels and to reduce collision in the presence of a surge of random access requests. Service class information for a plurality of service classes is stored at user equipment. The service class information for a service class includes at least one of a maximum and a minimum back off value; the maximum back off value being indicative of a maximum back off interval and the minimum back off value being indicative of a minimum back off interval. At least one of a maximum and a minimum back off value is determined based on a selected service class of the user equipment, and a back off interval is determined based on the determined back off value. The back off interval indicates a period of time the user equipment waits before the user equipment attempts a transmission.

    摘要: System(s) and method(s) that facilitate assignment mismatch recovery are provided. A projected level of resources required to satisfy one or more communication constraints (e.g., inter-cell and intra-cell interference) is generated. The projected resources are contrasted with scheduled resources and a determination is made as to whether a mismatch between assigned and projected resources exists. A mismatch is recovered through an adaptive response that feeds back magnitudes for the communication resources which are compatible with the communication constraints.
