A method for acquiring a multicast service by a user equipment, UE, comprising: receiving a user service description, USD message, the USD message including at least one frequency of a multicast service of interest to the UE; performing a search for other frequencies when the at least one frequency included in the USD message is not a current frequency, the search for other frequencies comprising: determining that a system information message is received, determining frequencies commonly included in the USD message and the system information message when the system information is received, determining that the common frequencies are neighboring cell frequencies, for an i-th common frequency, i = 1 to N, wherein N is a total number of common frequencies, and until the multicast service is acquired successfully, the search for other frequencies further comprising: setting a priority of the i-th common frequency to a highest priority, measuring a signal strength of the i-th common frequency, performing a cell reselection determination procedure based on the signal strength of the i-th common frequency, performing cell reselection to a cell of the i-th common frequency based on a result of the cell reselection determination procedure, acquiring the multicast service in the cell of the i-th common frequency when the cell reselection is performed, and determining if the multicast service is acquired successfully; and receiving the multicast service when the multicast service is acquired successfully. receiving a user service description, USD message, the USD message including at least one frequency of a multicast service of interest to the UE; performing a search for other frequencies when the at least one frequency included in the USD message is not a current frequency, the search for other frequencies comprising: determining that a system information message is received, determining frequencies commonly included in the USD message and the system information message when the system information is received, determining that the common frequencies are neighboring cell frequencies, for an i-th common frequency, i = 1 to N, wherein N is a total number of common frequencies, and until the multicast service is acquired successfully, the search for other frequencies further comprising: setting a priority of the i-th common frequency to a highest priority, measuring a signal strength of the i-th common frequency, performing a cell reselection determination procedure based on the signal strength of the i-th common frequency, performing cell reselection to a cell of the i-th common frequency based on a result of the cell reselection determination procedure, acquiring the multicast service in the cell of the i-th common frequency when the cell reselection is performed, and determining if the multicast service is acquired successfully; and determining that a system information message is received, determining frequencies commonly included in the USD message and the system information message when the system information is received, determining that the common frequencies are neighboring cell frequencies, for an i-th common frequency, i = 1 to N, wherein N is a total number of common frequencies, and until the multicast service is acquired successfully, the search for other frequencies further comprising: setting a priority of the i-th common frequency to a highest priority, measuring a signal strength of the i-th common frequency, performing a cell reselection determination procedure based on the signal strength of the i-th common frequency, performing cell reselection to a cell of the i-th common frequency based on a result of the cell reselection determination procedure, acquiring the multicast service in the cell of the i-th common frequency when the cell reselection is performed, and determining if the multicast service is acquired successfully; and setting a priority of the i-th common frequency to a highest priority, measuring a signal strength of the i-th common frequency, performing a cell reselection determination procedure based on the signal strength of the i-th common frequency, performing cell reselection to a cell of the i-th common frequency based on a result of the cell reselection determination procedure, acquiring the multicast service in the cell of the i-th common frequency when the cell reselection is performed, and determining if the multicast service is acquired successfully; and receiving the multicast service when the multicast service is acquired successfully.
